0
00:00:00,000 --> 00:00:01,617
那这里没有出现
1
00:00:01,617 --> 00:00:04,448
我们可以把它从这里再拖上来
2
00:00:04,448 --> 00:00:06,267
但是这个地方不够
3
00:00:06,267 --> 00:00:08,491
我们把这个地方放大一点
4
00:00:08,491 --> 00:00:11,928
但是你看，现在拖住这个是没法放大的
5
00:00:11,928 --> 00:00:13,950
你首先得选中这个框
6
00:00:13,950 --> 00:00:15,365
它这个有点
7
00:00:15,365 --> 00:00:16,781
操作有点迷惑
8
00:00:16,781 --> 00:00:19,409
你点这里是出不来什么东西的
9
00:00:19,409 --> 00:00:20,420
出来是图的（属性）
10
00:00:20,420 --> 00:00:22,240
它把这个框，跟这个图
11
00:00:23,420 --> 00:00:23,695
12
00:00:23,695 --> 00:00:25,900
你看，这个是框
13
00:00:27,810 --> 00:00:29,362
你看，隐掉框
14
00:00:29,362 --> 00:00:30,915
但是图还在哦
15
00:00:30,915 --> 00:00:31,950
这个是图
16
00:00:33,600 --> 00:00:34,750
这个是框
17
00:00:38,110 --> 00:00:38,362
18
00:00:38,362 --> 00:00:39,370
这出来了？
19
00:00:39,650 --> 00:00:41,031
出来就出来了
20
00:00:41,031 --> 00:00:42,413
这有点迷惑
21
00:00:42,413 --> 00:00:45,350
我们调一下那个框大小
22
00:00:48,620 --> 00:00:48,913
23
00:00:48,913 --> 00:00:51,851
右键点这个框
24
00:00:51,851 --> 00:00:53,320
它这个有点
25
00:00:53,600 --> 00:00:54,760
迷惑性
26
00:00:56,870 --> 00:00:57,086
27
00:00:57,086 --> 00:00:58,820
点到这个框这里
28
00:00:59,760 --> 00:01:00,767
点这个图
29
00:01:00,767 --> 00:01:01,775
这个不对
30
00:01:01,775 --> 00:01:03,790
点这个框，这有点
31
00:01:03,790 --> 00:01:07,820
这时候，这个框就可以变大变小了
32
00:01:10,350 --> 00:01:10,663
33
00:01:10,663 --> 00:01:11,290
这样
34
00:01:11,870 --> 00:01:14,030
那把这个挪到这边来
35
00:01:14,030 --> 00:01:15,110
这边净水
36
00:01:15,690 --> 00:01:16,443
废热
37
00:01:16,443 --> 00:01:17,950
你看它位置
38
00:01:20,400 --> 00:01:21,580
净水废热
39
00:01:21,580 --> 00:01:22,760
在右下角
40
00:01:23,570 --> 00:01:24,830
这里
41
00:01:25,110 --> 00:01:26,070
下来一点
42
00:01:27,560 --> 00:01:28,542
然后呢
43
00:01:28,542 --> 00:01:30,180
这个外部热
44
00:01:31,030 --> 00:01:33,580
左上角，下来一点
45
00:01:35,230 --> 00:01:36,020
这样
46
00:01:36,880 --> 00:01:37,660
对吧
47
00:01:40,360 --> 00:01:41,220
好
48
00:01:44,890 --> 00:01:45,640
那
49
00:01:46,360 --> 00:01:49,410
这个时候，我们还差一个什么
50
00:01:50,580 --> 00:01:52,132
接下来是这个
51
00:01:52,132 --> 00:01:53,020
这里有个
52
00:01:54,650 --> 00:01:56,770
stream，就是这个
53
00:01:58,140 --> 00:02:00,470
流这样一个概念
54
00:02:01,030 --> 00:02:02,227
那这个什么意思
55
00:02:02,227 --> 00:02:02,740
就是说
56
00:02:03,240 --> 00:02:04,520
表示说
57
00:02:06,710 --> 00:02:10,520
一个持续的，在行为持续过程中
58
00:02:12,090 --> 00:02:16,022
它依然可以有这个输入进来的
59
00:02:16,022 --> 00:02:17,410
不断的进来的
60
00:02:20,130 --> 00:02:21,639
如果没有这个的话
61
00:02:21,639 --> 00:02:22,582
意味着什么
62
00:02:22,582 --> 00:02:24,092
它是一次一次送的
63
00:02:24,092 --> 00:02:25,790
送完这个，消耗完之后
64
00:02:26,320 --> 00:02:29,857
这个相当于一个加工机
65
00:02:29,857 --> 00:02:31,184
这个输入进来
66
00:02:31,184 --> 00:02:33,837
它在里面加工，吐出这个输出
67
00:02:33,837 --> 00:02:34,280
对吧
68
00:02:35,870 --> 00:02:37,130
如果没有这个
69
00:02:37,130 --> 00:02:39,020
意味着，这批进来之后
70
00:02:39,810 --> 00:02:42,002
加工完了，再进下一批
71
00:02:42,002 --> 00:02:42,490
对吧
72
00:02:43,410 --> 00:02:46,203
等这里面这些操作
73
00:02:46,203 --> 00:02:47,999
嘎嘎嘎嘎嘎嘎搞完了
74
00:02:47,999 --> 00:02:49,995
到这里，再进下一批
75
00:02:49,995 --> 00:02:51,192
而这个是说什么
76
00:02:51,192 --> 00:02:52,390
在这个过程中
77
00:02:53,190 --> 00:02:56,153
比如说，我现在处在这一点上
78
00:02:56,153 --> 00:02:58,270
依然可以不断地进入
79
00:02:58,620 --> 00:02:59,146
这样来
80
00:02:59,146 --> 00:03:00,550
所以这个有个这个
81
00:03:00,850 --> 00:03:02,310
那这个在哪里呀
82
00:03:02,310 --> 00:03:03,770
也是参数里面的
83
00:03:05,410 --> 00:03:09,450
这个地方，在下面
84
00:03:10,650 --> 00:03:11,760
往上一点
85
00:03:13,090 --> 00:03:13,980
这里
86
00:03:15,140 --> 00:03:15,361
87
00:03:15,361 --> 00:03:16,690
这个地方选上
88
00:03:18,970 --> 00:03:22,920
但是呢，它这里要变成一个
89
00:03:24,040 --> 00:03:25,540
这种
90
00:03:27,410 --> 00:03:29,620
像它这样的一个显示
91
00:03:30,830 --> 00:03:31,752
怎么显示
92
00:03:31,752 --> 00:03:33,411
这个我就不知道了
93
00:03:33,411 --> 00:03:35,809
这个大家可以自己琢磨一下
94
00:03:35,809 --> 00:03:37,100
怎么在这里设置
95
00:03:38,610 --> 00:03:39,470
好
96
00:03:40,390 --> 00:03:41,350
这是
97
00:03:41,730 --> 00:03:43,020
这个活动的
98
00:03:43,510 --> 00:03:44,450
参数
99
00:03:49,130 --> 00:03:52,340
那么，接下来我们就来描述里面的
100
00:03:53,240 --> 00:03:54,156
这个了
101
00:03:54,156 --> 00:03:55,760
a1、a2、a3这个
102
00:03:56,500 --> 00:03:58,630
那a1是
103
00:03:59,050 --> 00:04:00,527
加热水，对吧
104
00:04:00,527 --> 00:04:02,300
这个是煮沸水
105
00:04:02,580 --> 00:04:05,155
那这些也同样是什么
106
00:04:05,155 --> 00:04:06,300
也同样是
107
00:04:06,580 --> 00:04:07,870
它的参数
108
00:04:08,470 --> 00:04:09,320
对不对
109
00:04:10,250 --> 00:04:10,536
110
00:04:10,536 --> 00:04:13,968
也就是说，加热水有一个参数
111
00:04:13,968 --> 00:04:18,830
也是这个冷水脏水
112
00:04:23,100 --> 00:04:23,411
113
00:04:23,411 --> 00:04:26,210
这个是
114
00:04:27,850 --> 00:04:30,470
加热水的那个热
115
00:04:31,550 --> 00:04:34,540
这个是热的脏水
116
00:04:35,220 --> 00:04:35,970
对吧
117
00:04:38,880 --> 00:04:39,606
然后呢
118
00:04:39,606 --> 00:04:40,090
这个
119
00:04:40,520 --> 00:04:43,290
是煮沸水的热
120
00:04:43,980 --> 00:04:45,721
然后热脏水进来
121
00:04:45,721 --> 00:04:46,717
然后煮沸
122
00:04:46,717 --> 00:04:48,210
然后蒸汽出来
123
00:04:48,630 --> 00:04:48,933
124
00:04:48,933 --> 00:04:50,756
蒸汽出来，对吧
125
00:04:50,756 --> 00:04:55,618
那我们先把这个东西的参数给加上
126
00:04:55,618 --> 00:04:56,530
水，热，水
127
00:04:56,810 --> 00:04:57,410
对吧
128
00:04:57,860 --> 00:04:58,720
在这里
129
00:04:58,720 --> 00:05:00,440
那就说明这个东西
130
00:05:01,300 --> 00:05:03,590
加热水这个活动
131
00:05:04,340 --> 00:05:06,389
就有这个参数了
132
00:05:06,389 --> 00:05:07,670
加热水在哪里
133
00:05:09,060 --> 00:05:09,860
这里
134
00:05:10,140 --> 00:05:13,600
同样，跟刚才一样的，添加参数
135
00:05:15,010 --> 00:05:16,040
叫什么
136
00:05:16,660 --> 00:05:16,931
137
00:05:16,931 --> 00:05:18,560
也是冷脏水
138
00:05:19,560 --> 00:05:22,020
冷的污水
139
00:05:24,010 --> 00:05:25,210
进来
140
00:05:26,930 --> 00:05:27,547
然后呢
141
00:05:27,547 --> 00:05:29,194
它的类型一样的
142
00:05:29,194 --> 00:05:31,870
跟刚才是一样的
143
00:05:38,430 --> 00:05:38,741
好
144
00:05:38,741 --> 00:05:40,300
这是进来的
145
00:05:41,910 --> 00:05:43,440
还有一个是
146
00:05:46,100 --> 00:05:48,550
加热水的热量
147
00:05:52,360 --> 00:05:53,850
同样是热
148
00:06:21,380 --> 00:06:22,300
好
149
00:06:22,860 --> 00:06:24,890
还有一个是输出的
150
00:06:25,510 --> 00:06:26,970
热的污水
151
00:06:33,430 --> 00:06:35,120
热的污水
152
00:06:36,880 --> 00:06:38,010
污水
153
00:06:43,110 --> 00:06:43,381
154
00:06:43,381 --> 00:06:45,010
这同样也是水
155
00:06:56,340 --> 00:06:59,377
但是这个是，这里
156
00:06:59,377 --> 00:07:01,200
这个是输出的
157
00:07:03,390 --> 00:07:03,657
好
158
00:07:03,657 --> 00:07:04,725
这个有了
159
00:07:04,725 --> 00:07:07,130
你看，我们把它拖上来
160
00:07:10,750 --> 00:07:11,085
161
00:07:11,085 --> 00:07:12,760
这就是一个
162
00:07:13,070 --> 00:07:14,395
调用，加热水
163
00:07:14,395 --> 00:07:16,250
然后把它的那个
164
00:07:16,590 --> 00:07:21,026
这个问，你要不要把它里面包含的结构给加上
165
00:07:21,026 --> 00:07:23,920
那都加上，这几个参数都带上了
166
00:07:24,200 --> 00:07:25,090
OK
167
00:07:26,260 --> 00:07:26,538
好
168
00:07:26,538 --> 00:07:28,210
你看，这里就有
169
00:07:31,300 --> 00:07:32,744
加热水，对吧
170
00:07:32,744 --> 00:07:35,343
冷的污水，对应在这里
171
00:07:35,343 --> 00:07:37,365
然后呢，往上挪
172
00:07:37,365 --> 00:07:38,810
热的污水
173
00:07:39,170 --> 00:07:40,130
在这边
174
00:07:40,130 --> 00:07:42,290
热的污水在哪边
175
00:07:42,840 --> 00:07:45,110
这边的中间这里
176
00:07:45,390 --> 00:07:45,664
177
00:07:45,664 --> 00:07:47,037
加热水的热
178
00:07:47,037 --> 00:07:48,410
对着这个
179
00:07:49,370 --> 00:07:51,680
这样刚好一会我们就
180
00:07:52,390 --> 00:07:53,644
对着过来
181
00:07:53,644 --> 00:07:54,062
182
00:07:54,062 --> 00:07:54,690
对着过来
183
00:07:55,410 --> 00:07:56,500
加热水
184
00:08:01,490 --> 00:08:02,280
这篇关于什么是系统工程（字幕）23的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
