什么是系统工程（字幕）43

本文主要是介绍什么是系统工程（字幕）43，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

0
00:00:02,230 --> 00:00:03,473
怎么修改呢

1
00:00:03,473 --> 00:00:05,711
那我们就要看这个

2
00:00:05,711 --> 00:00:07,950
图16.24这个地方

3
00:00:10,500 --> 00:00:11,430
那

4
00:00:12,730 --> 00:00:15,157
主要的改动是这么几个

5
00:00:15,157 --> 00:00:17,180
一个是添加了一个分区

6
00:00:17,720 --> 00:00:17,972

7
00:00:17,972 --> 00:00:18,980
这个地方

8
00:00:19,990 --> 00:00:22,560
多了一个泳道

9
00:00:22,910 --> 00:00:27,220
叫做分流器装配

10
00:00:29,610 --> 00:00:30,317
然后呢

11
00:00:30,317 --> 00:00:32,440
这里又添加了个活动

12
00:00:33,870 --> 00:00:35,680
叫分流给水

13
00:00:38,060 --> 00:00:38,690

14
00:00:38,690 --> 00:00:40,160
拖上来就是a5

15
00:00:41,650 --> 00:00:42,543
然后呢

16
00:00:42,543 --> 00:00:44,330
这里多了一个

17
00:00:46,820 --> 00:00:48,930
这个端口

18
00:00:49,550 --> 00:00:50,840
或者说引脚

19
00:00:52,070 --> 00:00:55,350
这个分流就直接从这里出去了

20
00:00:56,050 --> 00:00:56,780

21
00:00:58,470 --> 00:01:01,350
起名叫旁路

22
00:01:02,850 --> 00:01:06,337
允许过热的水，温度过高的水

23
00:01:06,337 --> 00:01:07,773
因为它没有办法

24
00:01:07,773 --> 00:01:09,210
刚才那个公式嘛

25
00:01:10,140 --> 00:01:13,340
冷凝器就解决不了了

26
00:01:13,770 --> 00:01:15,062
那么像这样的水

27
00:01:15,062 --> 00:01:16,170
我们就把它给

28
00:01:16,610 --> 00:01:17,660
直接就

29
00:01:17,940 --> 00:01:19,330
排出系统外

30
00:01:20,970 --> 00:01:23,891
那就多了这样几个地方

31
00:01:23,891 --> 00:01:24,790
要改进的

32
00:01:25,280 --> 00:01:28,417
那么这个画图怎么改进的过程

33
00:01:28,417 --> 00:01:31,330
怎么把这个图改成这个的过程

34
00:01:32,080 --> 00:01:33,670
我们就不

35
00:01:34,760 --> 00:01:35,765
一一展示了

36
00:01:35,765 --> 00:01:38,380
因为前面我们已经画了很多了

37
00:01:38,380 --> 00:01:40,190
操作都是一模一样的

38
00:01:40,820 --> 00:01:43,520
这是一张

39
00:01:44,710 --> 00:01:44,984

40
00:01:44,984 --> 00:01:49,923
修改后的蒸馏器行为的图

41
00:01:49,923 --> 00:01:51,843
加这么一张图

42
00:01:51,843 --> 00:01:52,392
对吧

43
00:01:52,392 --> 00:01:52,666

44
00:01:52,666 --> 00:01:53,490
然后呢

45
00:01:53,840 --> 00:01:55,710
把这个改上去

0
00:00:01,110 --> 00:00:03,540
这个就是画好的

1
00:00:03,820 --> 00:00:07,130
修正蒸馏器行为的图

2
00:00:08,310 --> 00:00:08,617

3
00:00:08,617 --> 00:00:11,380
这个，跟我们刚才这个

4
00:00:12,220 --> 00:00:13,806
可以对比一下

5
00:00:13,806 --> 00:00:14,260
对吧

6
00:00:16,130 --> 00:00:18,331
你看这个地方

7
00:00:18,331 --> 00:00:20,807
它是直接给分区

8
00:00:20,807 --> 00:00:23,284
就直接命了一个名

9
00:00:23,284 --> 00:00:24,660
没有从这个

10
00:00:26,690 --> 00:00:28,370
这个部件里面

11
00:00:28,930 --> 00:00:29,362

12
00:00:29,362 --> 00:00:30,660
来取

13
00:00:32,040 --> 00:00:34,990
所以我们这里就照做了

14
00:00:36,390 --> 00:00:37,090

15
00:00:37,680 --> 00:00:39,010
这个地方

16
00:00:42,280 --> 00:00:45,722
然后这里你看，热的污水本来直接过来嘛

17
00:00:45,722 --> 00:00:46,330
现在呢

18
00:00:46,610 --> 00:00:49,060
先到分流给水这里

19
00:00:50,570 --> 00:00:52,020
到这里之后

20
00:00:52,390 --> 00:00:54,485
你看，它分成两路

21
00:00:54,485 --> 00:00:56,880
一路是直接出去的

22
00:00:57,160 --> 00:00:59,100
这个叫of2a

23
00:01:00,080 --> 00:01:02,900
另外一路从这里出来

24
00:01:03,180 --> 00:01:03,647
过来

25
00:01:03,647 --> 00:01:05,050
这是of2b

26
00:01:07,060 --> 00:01:07,360

27
00:01:07,360 --> 00:01:08,560
分成两路

28
00:01:10,770 --> 00:01:12,243
相当于分流了

29
00:01:12,243 --> 00:01:14,698
进来一个，出去两个

30
00:01:14,698 --> 00:01:15,680
分流给水

31
00:01:16,910 --> 00:01:17,960
在这里

32
00:01:19,240 --> 00:01:21,370
这里也多了一个

33
00:01:21,750 --> 00:01:23,850
新的引脚

34
00:01:23,850 --> 00:01:24,200
对

35
00:01:24,770 --> 00:01:26,640
旁路的一个出口

0
00:00:00,000 --> 00:00:04,480
接下来呢，就是要修改蒸馏器的内部结构了

1
00:00:05,720 --> 00:00:08,240
那要改几个地方

2
00:00:09,600 --> 00:00:11,470
就这个IBD里面

3
00:00:11,840 --> 00:00:13,240
改几个地方

4
00:00:13,580 --> 00:00:15,270
一个就是

5
00:00:16,030 --> 00:00:17,960
多了一个新的部件

6
00:00:18,270 --> 00:00:18,510

7
00:00:18,510 --> 00:00:20,430
就这个分流器

8
00:00:23,290 --> 00:00:27,650
那么它的类型是一个三通接头

9
00:00:27,930 --> 00:00:28,215

10
00:00:28,215 --> 00:00:31,360
也就是说，用三通接头来扮演

11
00:00:31,650 --> 00:00:33,390
分流器的角色

12
00:00:35,400 --> 00:00:36,490
这个地方

13
00:00:41,760 --> 00:00:42,013

14
00:00:42,013 --> 00:00:43,280
类型在这里

15
00:00:44,360 --> 00:00:45,545
第二个呢，多了

16
00:00:45,545 --> 00:00:47,520
另外一个部件，就是一个

17
00:00:47,800 --> 00:00:51,843
给水，类型是阀门

18
00:00:51,843 --> 00:00:56,510
用一个阀门来扮演这个给水的

19
00:00:57,210 --> 00:00:58,580
这样的一个角色

20
00:00:59,990 --> 00:01:02,850
那你看，阀门这里用了两遍

21
00:01:02,850 --> 00:01:04,756
这有个阀门

22
00:01:04,756 --> 00:01:05,710
是排污的

23
00:01:06,450 --> 00:01:07,790
这是给水的

24
00:01:11,990 --> 00:01:14,150
然后这里多了一个

25
00:01:15,170 --> 00:01:17,030
流体端口

26
00:01:17,410 --> 00:01:17,834

27
00:01:17,834 --> 00:01:19,531
出去的

28
00:01:19,531 --> 00:01:20,380
旁路

29
00:01:22,870 --> 00:01:27,590
那我们接下来就要根据这个图来修改了

30
00:01:28,650 --> 00:01:31,941
那这里只是显示IBD

31
00:01:31,941 --> 00:01:32,490
但实际上

32
00:01:33,940 --> 00:01:36,010
它这个图只是一个结果

33
00:01:36,850 --> 00:01:38,838
你里面还要做很多事情

34
00:01:38,838 --> 00:01:40,430
你看，这个三通接头

35
00:01:40,730 --> 00:01:42,110
之前就没有

36
00:01:42,480 --> 00:01:43,598
没有出现过

37
00:01:43,598 --> 00:01:44,270
对不对

38
00:01:46,650 --> 00:01:48,290
那这个是一个新的

39
00:01:48,290 --> 00:01:51,160
所以呢，我们还不能直接在这里画

40
00:01:52,110 --> 00:01:53,680
还要回到

41
00:01:54,360 --> 00:01:55,740
那个

42
00:01:56,140 --> 00:01:57,520
块定义图那里

43
00:01:57,930 --> 00:01:58,262

44
00:01:58,262 --> 00:01:59,590
给它添加

45
00:01:59,930 --> 00:02:01,240
这些块

46
00:02:01,520 --> 00:02:01,760

47
00:02:01,760 --> 00:02:03,440
还有添加它们的

48
00:02:04,660 --> 00:02:05,960
组合关系

49
00:02:06,240 --> 00:02:07,290
等等

50
00:02:07,570 --> 00:02:09,380
那下面我们来画一下

这篇关于什么是系统工程（字幕）43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！
