0
00:00:00,740 --> 00:00:03,200
但是呢，我们往后面看

1
00:00:04,100 --> 00:00:08,920
刚才我们讲到那个说，应该是组合关系

2
00:00:08,920 --> 00:00:09,522
对吧

3
00:00:09,522 --> 00:00:11,330
不是泛化关系

4
00:00:12,520 --> 00:00:13,671
但是往后面看

5
00:00:13,671 --> 00:00:15,783
为什么它用泛化关系

6
00:00:15,783 --> 00:00:18,278
实际上它也是一个无奈的选择

7
00:00:18,278 --> 00:00:19,430
因为我们后面

8
00:00:20,130 --> 00:00:23,646
画到约束块的时候

9
00:00:23,646 --> 00:00:25,990
我们看那个约束块上

10
00:00:28,080 --> 00:00:29,770
如果你定义

11
00:00:30,050 --> 00:00:31,770
它的类型是

12
00:00:32,950 --> 00:00:35,790
参数类型是实数、整数

13
00:00:36,740 --> 00:00:37,730
然后呢

14
00:00:37,730 --> 00:00:40,370
你把这个值

15
00:00:40,710 --> 00:00:44,070
把它绑定到那个参数上面去的话

16
00:00:46,850 --> 00:00:49,740
那如果说要能够使这个公式能够

17
00:00:51,430 --> 00:00:52,800
运行的话

18
00:00:53,470 --> 00:00:56,310
确实是必须说水温是

19
00:00:57,770 --> 00:00:59,310
实数的一种

20
00:01:00,730 --> 00:01:01,015

21
00:01:01,015 --> 00:01:01,870
所以呢

22
00:01:02,150 --> 00:01:03,560
它这里面的话

23
00:01:04,470 --> 00:01:05,870
就会存在这个问题

24
00:01:06,210 --> 00:01:09,738
那另外一种就是，一会我们也会讲到

25
00:01:09,738 --> 00:01:11,620
就是说，如果你那个

26
00:01:12,630 --> 00:01:14,010
约束块上

27
00:01:15,860 --> 00:01:19,122
你定义那个参数类型不是实数

28
00:01:19,122 --> 00:01:23,389
而是就是一个温度的值类型

29
00:01:23,389 --> 00:01:23,640

30
00:01:24,020 --> 00:01:25,860
是一个值类型

31
00:01:26,350 --> 00:01:28,380
有意义的值类型

32
00:01:29,500 --> 00:01:33,063
那么在这里就可以用刚才那个了

33
00:01:33,063 --> 00:01:36,850
因为我们直接就跟那个水温就挂上了

34
00:01:41,480 --> 00:01:43,780
所以呢，这个我们一会

35
00:01:44,530 --> 00:01:46,824
还会再看这个问题

36
00:01:46,824 --> 00:01:49,825
就是说，它为什么前面我们讲应该是这样

37
00:01:49,825 --> 00:01:52,120
但是呢，它涉及到另外一个问题

38
00:01:52,400 --> 00:01:55,100
就是我们一会画那个约束块的时候

39
00:01:56,110 --> 00:01:58,920
怎么表达约束块的参数的问题

40
00:02:01,360 --> 00:02:05,161
那现在我们先把其他的几个给加上去

41
00:02:05,161 --> 00:02:06,950
其他几个给加上去

42
00:02:09,940 --> 00:02:11,490
比如说，还有什么

43
00:02:11,770 --> 00:02:12,145

44
00:02:12,145 --> 00:02:14,400
我们来看这个

45
00:02:18,310 --> 00:02:20,390
刚才我们有了一个

46
00:02:26,080 --> 00:02:27,620
温度，对吧

47
00:02:28,920 --> 00:02:29,960
然后呢

48
00:02:30,600 --> 00:02:31,750
摄氏度

49
00:02:32,700 --> 00:02:33,273
然后呢

50
00:02:33,273 --> 00:02:36,140
我们认为它那个是描述温度的

51
00:02:38,200 --> 00:02:39,951
那我们还需要什么

52
00:02:39,951 --> 00:02:42,141
先把单位给加上

53
00:02:42,141 --> 00:02:44,550
比如说，我们一个一个加上

54
00:02:45,950 --> 00:02:49,540
这个，温度这里有了

55
00:02:49,900 --> 00:02:52,493
下来，我们看，比热，对吧

56
00:02:52,493 --> 00:02:52,781

57
00:02:52,781 --> 00:02:54,510
比热这是一个

58
00:02:56,610 --> 00:02:57,275
比热

59
00:02:57,275 --> 00:02:59,270
单位是多少来着

60
00:03:00,520 --> 00:03:02,900
比热单位是

61
00:03:05,430 --> 00:03:06,340
卡

62
00:03:06,620 --> 00:03:07,140

63
00:03:07,140 --> 00:03:09,740
每克·摄氏度

64
00:03:13,240 --> 00:03:14,034
然后呢

65
00:03:14,034 --> 00:03:15,622
符号是这个

66
00:03:15,622 --> 00:03:17,210
那我们同样

67
00:03:17,530 --> 00:03:18,360
加一个

68
00:03:18,730 --> 00:03:19,880

69
00:03:19,880 --> 00:03:21,030

70
00:03:23,180 --> 00:03:25,985
我们把这些放到右边来

71
00:03:25,985 --> 00:03:26,920
免得一会

72
00:03:27,200 --> 00:03:28,600
施展不开

73
00:03:32,890 --> 00:03:33,900

74
00:03:34,710 --> 00:03:35,128
好

75
00:03:35,128 --> 00:03:36,800
再来

76
00:03:37,900 --> 00:03:39,470
单位是

77
00:03:42,920 --> 00:03:43,165

78
00:03:43,165 --> 00:03:44,390
我们用中文

79
00:03:49,280 --> 00:03:50,260
卡

80
00:03:56,320 --> 00:03:57,100
克

81
00:03:58,180 --> 00:03:59,894
中文应该是个点

82
00:03:59,894 --> 00:04:01,180
不是那个

83
00:04:01,600 --> 00:04:03,553
不是那个星号

84
00:04:03,553 --> 00:04:04,390
摄氏度

85
00:04:10,900 --> 00:04:11,293
好

86
00:04:11,293 --> 00:04:13,260
然后呢，这个

87
00:04:15,100 --> 00:04:16,950
符号是

88
00:04:21,280 --> 00:04:23,770
cal

89
00:04:40,730 --> 00:04:41,250
好

90
00:04:41,250 --> 00:04:42,290
这是

91
00:04:42,580 --> 00:04:47,370
单位，那同样，这个是

92
00:04:47,770 --> 00:04:50,340
描述的是比热

93
00:04:59,050 --> 00:04:59,810
好

94
00:05:00,960 --> 00:05:01,930
下一个

95
00:05:08,990 --> 00:05:10,303
这个传热速率

96
00:05:10,303 --> 00:05:11,804
这个不是水的

97
00:05:11,804 --> 00:05:12,180
这是

98
00:05:13,190 --> 00:05:13,994
另外一个的

99
00:05:13,994 --> 00:05:15,442
我们先把水给搞定了

100
00:05:15,442 --> 00:05:15,924
潜热

101
00:05:15,924 --> 00:05:16,890
下一个是潜热

102
00:05:18,140 --> 00:05:18,836
潜热

103
00:05:18,836 --> 00:05:19,880
然后呢

104
00:05:20,260 --> 00:05:21,910
卡每克

105
00:05:51,350 --> 00:05:53,430
然后这个符号

106
00:06:03,540 --> 00:06:08,520
是gm，潜热这个

107
00:06:08,820 --> 00:06:10,500
这个是

108
00:06:10,780 --> 00:06:12,290
cal/gm 

109
00:06:25,310 --> 00:06:25,654
好

110
00:06:25,654 --> 00:06:27,030
这是潜热

111
00:06:27,580 --> 00:06:29,510
还有一个是

112
00:06:29,920 --> 00:06:31,930
跟水相关的

113
00:06:33,180 --> 00:06:34,368
这个卡每秒

114
00:06:34,368 --> 00:06:35,320
这个不是

115
00:06:37,080 --> 00:06:37,266

116
00:06:37,266 --> 00:06:38,943
还有这个质量流率

117
00:06:38,943 --> 00:06:40,620
质量流率跟水相关的

118
00:06:40,900 --> 00:06:41,140

119
00:06:41,140 --> 00:06:41,620
这个

120
00:06:44,580 --> 00:06:46,690
是克每秒

121
00:06:49,860 --> 00:06:50,820
小一点

122
00:07:20,390 --> 00:07:22,490
实际上符号应该是什么

123
00:07:22,910 --> 00:07:25,642
应该是g/s这样的

124
00:07:25,642 --> 00:07:28,871
但是呢，书上这样写就拉倒了

125
00:07:28,871 --> 00:07:29,368

126
00:07:29,368 --> 00:07:31,851
你既然是符号了

127
00:07:31,851 --> 00:07:33,093
怎么还用

128
00:07:33,093 --> 00:07:36,074
还用这个gm什么之类的

129
00:07:36,074 --> 00:07:38,310
应该就g/s这样就行了

130
00:07:49,250 --> 00:07:51,880
而这个描述的是

131
00:07:52,160 --> 00:07:53,470
质量流率

132
00:08:04,890 --> 00:08:05,197
好

133
00:08:05,197 --> 00:08:06,425
这是水的

134
00:08:06,425 --> 00:08:09,190
还有一个是描述这个

135
00:08:10,150 --> 00:08:12,640
蒸馏器的

136
00:08:12,920 --> 00:08:13,178

137
00:08:13,178 --> 00:08:14,210
蒸馏器的

138
00:08:15,550 --> 00:08:17,350
叫传热速率

139
00:08:17,750 --> 00:08:20,500
单位是卡每秒

140
00:08:49,970 --> 00:08:51,836
卡每秒

141
00:08:51,836 --> 00:08:52,770
这个是

142
00:08:56,790 --> 00:08:57,276
是

143
00:08:57,276 --> 00:08:58,250
我看

144
00:09:00,220 --> 00:09:01,900
卡每秒

145
00:09:03,820 --> 00:09:05,460
cal 

146
00:09:06,110 --> 00:09:07,000
second 

147
00:09:10,520 --> 00:09:10,772
好

148
00:09:10,772 --> 00:09:12,540
单位就这样了

149
00:09:13,560 --> 00:09:15,400
那接下来，我们把

150
00:09:16,480 --> 00:09:17,991
那个值类型

151
00:09:17,991 --> 00:09:20,510
值类型放上去

152
00:09:22,410 --> 00:09:23,677
就这边的了

153
00:09:23,677 --> 00:09:25,199
这边的命名了

154
00:09:25,199 --> 00:09:28,241
水温，质量流率了

155
00:09:28,241 --> 00:09:29,002
质量流率

156
00:09:29,002 --> 00:09:30,270
然后这个是

157
00:09:32,370 --> 00:09:33,520

158
00:09:34,640 --> 00:09:35,830
潜热

159
00:09:36,230 --> 00:09:36,518

160
00:09:36,518 --> 00:09:38,830
传热速率，就这样

161
00:09:43,030 --> 00:09:44,620
那我们就

162
00:09:45,160 --> 00:09:46,680
把这个给

163
00:09:49,950 --> 00:09:53,960
加上，一个一个加上

164
00:09:55,910 --> 00:09:58,385
水温，下来是比热，是吧

165
00:09:58,385 --> 00:09:58,660

166
00:09:58,660 --> 00:09:59,210
比热

167
00:10:00,330 --> 00:10:01,990
一个值类型

168
00:10:03,150 --> 00:10:04,560
叫比热

169
00:10:09,890 --> 00:10:12,490
同样，这里设置它的

170
00:10:17,600 --> 00:10:19,720
这个就是比热了

171
00:10:21,180 --> 00:10:22,210
单位

172
00:10:23,300 --> 00:10:25,010
单位是

173
00:10:26,230 --> 00:10:28,240
卡/克·摄氏度

174
00:10:29,270 --> 00:10:30,350
这个是吧

175
00:10:31,760 --> 00:10:33,686
然后组合到这里

176
00:10:33,686 --> 00:10:34,650
但是我们

177
00:10:35,470 --> 00:10:37,450
考虑到一会的

178
00:10:37,730 --> 00:10:39,080
约束块的话

179
00:10:39,080 --> 00:10:40,430
我们这里就干脆

180
00:10:40,800 --> 00:10:41,390

181
00:10:41,670 --> 00:10:43,750
还是遵从那个

182
00:10:44,780 --> 00:10:48,850
指南里面的用法，泛化

183
00:10:49,610 --> 00:10:50,695
但刚才也说了

184
00:10:50,695 --> 00:10:51,600
这个实际上是

185
00:10:53,480 --> 00:10:55,350
不合理的

186
00:10:57,120 --> 00:10:57,790
这样

187
00:11:02,070 --> 00:11:02,508

188
00:11:02,508 --> 00:11:04,700
比热，下来是

189
00:11:05,510 --> 00:11:07,283
潜热，质量流率

190
00:11:07,283 --> 00:11:07,790
潜热

191
00:11:19,180 --> 00:11:19,890

192
00:11:20,520 --> 00:11:22,240
单位是

193
00:11:22,870 --> 00:11:23,440

194
00:11:24,270 --> 00:11:25,390
卡每克

195
00:11:34,270 --> 00:11:34,672
好

196
00:11:34,672 --> 00:11:37,090
还有质量流率

197
00:11:54,100 --> 00:11:55,950
是克每秒

198
00:12:03,650 --> 00:12:05,270
这些都是实数

199
00:12:07,020 --> 00:12:07,950

200
00:12:08,390 --> 00:12:10,790
还有一个是

201
00:12:12,220 --> 00:12:13,500
传热速率

202
00:12:14,070 --> 00:12:16,150
传热速率，我看，它怎么命名的

203
00:12:18,790 --> 00:12:19,910

204
00:12:21,460 --> 00:12:22,490
这个

205
00:12:25,120 --> 00:12:27,010
这个q1

206
00:12:27,890 --> 00:12:30,190

207
00:12:31,640 --> 00:12:32,550

208
00:12:33,410 --> 00:12:34,820
就这个，是吧

209
00:12:36,690 --> 00:12:38,730

210
00:12:41,680 --> 00:12:48,494
那它就叫dq/dt，这是它的名字

211
00:12:48,494 --> 00:12:49,630
是这个，然后这个

212
00:12:50,830 --> 00:12:51,686
的名字

213
00:12:51,686 --> 00:12:53,398
应该是这个

214
00:12:53,398 --> 00:12:55,324
那我们就以这个命名

215
00:12:55,324 --> 00:12:56,823

216
00:12:56,823 --> 00:12:58,535
就不是这个了

217
00:12:58,535 --> 00:13:01,960
这个命名我们按照这上面来

218
00:13:02,240 --> 00:13:04,080
dq是微分

219
00:13:06,560 --> 00:13:07,410
dt

220
00:13:10,050 --> 00:13:10,750

221
00:13:15,630 --> 00:13:15,894

222
00:13:15,894 --> 00:13:19,062
这个质量流率，搞错了

223
00:13:19,062 --> 00:13:19,326

224
00:13:19,326 --> 00:13:21,174
质量流率，搞错

225
00:13:21,174 --> 00:13:22,230
质量流率

226
00:13:23,130 --> 00:13:23,344

227
00:13:23,344 --> 00:13:24,630
再来一个这个

228
00:13:35,380 --> 00:13:36,050
好

229
00:13:38,580 --> 00:13:39,320

230
00:13:40,320 --> 00:13:41,710
这个是

231
00:13:41,990 --> 00:13:43,300
卡每秒

232
00:13:57,450 --> 00:13:57,788
好

233
00:13:57,788 --> 00:14:00,160
这样的话，我们的

234
00:14:00,510 --> 00:14:02,840
这个值类型有了

235
00:14:04,380 --> 00:14:08,388
那上面这个是水的，那我们就跟刚才一样

236
00:14:08,388 --> 00:14:10,510
把它拖到水里面去

237
00:14:13,980 --> 00:14:16,720
还是跟之前的操作一样

238
00:14:18,160 --> 00:14:18,443

239
00:14:18,443 --> 00:14:20,141
拖进来就行了

240
00:14:20,141 --> 00:14:20,424

241
00:14:20,424 --> 00:14:21,840
那几个是水的

242
00:14:22,340 --> 00:14:23,530
潜热

243
00:14:34,910 --> 00:14:35,970
比热

244
00:14:42,130 --> 00:14:42,428

245
00:14:42,428 --> 00:14:43,620
质量流率

246
00:14:53,730 --> 00:14:55,040

247
00:15:01,970 --> 00:15:03,480
然后回到这里

248
00:15:04,360 --> 00:15:04,660

249
00:15:04,660 --> 00:15:06,760
水有四个值

250
00:15:06,760 --> 00:15:07,360
对吧

251
00:15:14,410 --> 00:15:16,530
那这是

252
00:15:18,730 --> 00:15:19,990
这个了

253
00:15:22,600 --> 00:15:23,766
那我们来看

254
00:15:23,766 --> 00:15:24,700
你看，这里

255
00:15:25,650 --> 00:15:27,490
还需要建一个什么

256
00:15:29,300 --> 00:15:31,793
这样一个

257
00:15:31,793 --> 00:15:33,040
你看它是

258
00:15:33,320 --> 00:15:36,372
叫初始蒸馏器分析这样一个block

259
00:15:36,372 --> 00:15:40,733
block里面有一个初始蒸馏器，这样的一个蒸馏器

260
00:15:40,733 --> 00:15:42,260
然后里面有main1

261
00:15:44,140 --> 00:15:45,370
什么什么什么

262
00:15:46,180 --> 00:15:47,260
这个

263
00:15:47,920 --> 00:15:49,588
我们之前都没有

264
00:15:49,588 --> 00:15:50,840
要从头建

265
00:15:53,550 --> 00:15:55,728
要建一个block，要什么

266
00:15:55,728 --> 00:15:56,600
但是

267
00:15:57,020 --> 00:16:00,020
你要只是模仿这张图的话

268
00:16:00,300 --> 00:16:03,716
另外一个方法就是，你直接放一个property

269
00:16:03,716 --> 00:16:06,492
我们看简易的模仿

270
00:16:06,492 --> 00:16:07,132
怎么模仿

271
00:16:07,132 --> 00:16:08,200
放一个property

272
00:16:08,200 --> 00:16:11,190
然后就直接敲这些字就可以了

273
00:16:12,720 --> 00:16:14,620
那我们先

274
00:16:15,310 --> 00:16:17,294
展示一个简易方法

275
00:16:17,294 --> 00:16:18,617
然后再展示

276
00:16:18,617 --> 00:16:20,601
如果说要严格的方法

277
00:16:20,601 --> 00:16:22,365
怎么做

278
00:16:22,365 --> 00:16:24,350
那先解决这个问题

279
00:16:25,630 --> 00:16:27,448
那下面我们来解决这个问题

280
00:16:27,448 --> 00:16:28,510
约束这个问题

281
00:16:30,300 --> 00:16:30,503

282
00:16:30,503 --> 00:16:31,930
约束块这个问题

283
00:16:32,890 --> 00:16:35,680
先把这个约束块给建起来再说

284
00:16:35,680 --> 00:16:36,110
对吧

285
00:16:37,000 --> 00:16:39,620
那我们来建一下这个约束块
