00:00:00,000 --> 00:00:02,490
那么下一个图就是
1
00:00:02,780 --> 00:00:05,530
图16.13这个图了
2
00:00:06,350 --> 00:00:08,120
那么这个图的话
3
00:00:09,370 --> 00:00:11,400
它是派生了一个
4
00:00:12,940 --> 00:00:15,450
排空残渣的需求
5
00:00:16,490 --> 00:00:20,162
因为前面只是说蒸馏水嘛
6
00:00:20,162 --> 00:00:21,010
这个水
7
00:00:21,980 --> 00:00:22,702
沸腾
8
00:00:22,702 --> 00:00:24,146
然后蒸发上去
9
00:00:24,146 --> 00:00:25,590
然后冷凝下来
10
00:00:26,330 --> 00:00:29,910
并没有提到这个残渣的事情
11
00:00:31,560 --> 00:00:32,373
然后呢
12
00:00:32,373 --> 00:00:34,270
这里有个DS.7
13
00:00:35,070 --> 00:00:36,370
这个需求
14
00:00:38,320 --> 00:00:39,760
就蒸馏器
15
00:00:43,130 --> 00:00:45,284
煮沸这个需求
16
00:00:45,284 --> 00:00:47,200
它就派生出了一个
17
00:00:47,520 --> 00:00:49,370
残渣移除这个
18
00:00:50,320 --> 00:00:51,320
需求
19
00:00:53,430 --> 00:00:57,830
蒸馏器应包含一个移除蒸馏过程中
20
00:00:58,110 --> 00:01:00,750
产生的残渣的机制
21
00:01:01,480 --> 00:01:02,060
22
00:01:02,400 --> 00:01:04,490
下面给出来理由
23
00:01:05,830 --> 00:01:07,720
挥发物质
24
00:01:07,720 --> 00:01:09,400
沉淀物如果不移除
25
00:01:09,400 --> 00:01:11,080
会在蒸馏器内聚集
26
00:01:11,080 --> 00:01:11,290
27
00:01:11,290 --> 00:01:12,550
这些
28
00:01:14,200 --> 00:01:15,270
也就是说
29
00:01:15,550 --> 00:01:17,610
我们需要添加一条
30
00:01:18,760 --> 00:01:20,140
新的需求
31
00:01:20,830 --> 00:01:21,171
32
00:01:21,171 --> 00:01:24,240
派生它，添加一个理由
33
00:01:26,940 --> 00:01:30,760
那这里面，你看这里，这个图是一张新的图
34
00:01:31,040 --> 00:01:31,230
35
00:01:31,230 --> 00:01:32,940
它在一张新图上面描述
36
00:01:32,940 --> 00:01:33,700
也就是说，把
37
00:01:35,600 --> 00:01:36,760
这个
38
00:01:37,140 --> 00:01:38,190
元素
39
00:01:38,570 --> 00:01:41,590
这个需求单独拿出来
40
00:01:44,580 --> 00:01:47,270
在图上单独画
41
00:01:49,580 --> 00:01:50,500
图
42
00:01:50,780 --> 00:01:52,810
跟那个模型元素
43
00:01:53,090 --> 00:01:55,321
是多对多的，一个模型元素
44
00:01:55,321 --> 00:01:57,350
可以出现在很多张图上
45
00:01:58,060 --> 00:02:01,710
图可以看作是模型元素的一个视图嘛
46
00:02:01,710 --> 00:02:02,140
对吧
47
00:02:04,610 --> 00:02:08,360
所以呢，你看DS.7这条需求
48
00:02:09,320 --> 00:02:11,360
在之前的图上
49
00:02:13,480 --> 00:02:14,790
可以存在
50
00:02:15,340 --> 00:02:16,720
也可以怎么样
51
00:02:17,610 --> 00:02:19,770
在别的图上也可以存在
52
00:02:21,980 --> 00:02:23,270
还是它
53
00:02:27,980 --> 00:02:31,440
那针对这个图我们也评点一下
54
00:02:31,720 --> 00:02:34,270
第一个，命名的问题了
55
00:02:34,550 --> 00:02:34,872
56
00:02:34,872 --> 00:02:39,058
这个图的名称叫排空残渣派生
57
00:02:39,058 --> 00:02:40,990
这个派生是
58
00:02:43,910 --> 00:02:44,115
59
00:02:44,115 --> 00:02:47,190
这个后面不要的
60
00:02:48,340 --> 00:02:49,770
因为你想想
61
00:02:53,790 --> 00:02:54,700
B
62
00:02:54,980 --> 00:02:56,030
派生A
63
00:02:56,310 --> 00:02:57,170
对吧
64
00:02:57,930 --> 00:03:00,400
那你说B是派生
65
00:03:01,410 --> 00:03:03,554
A是那个
66
00:03:03,554 --> 00:03:03,822
或者说
67
00:03:03,822 --> 00:03:04,894
B是儿子
68
00:03:04,894 --> 00:03:05,966
A是父亲
69
00:03:05,966 --> 00:03:06,502
对吧
70
00:03:06,502 --> 00:03:10,523
但实际上有没有别的会派生B
71
00:03:10,523 --> 00:03:12,400
很可能C又派生B
72
00:03:13,850 --> 00:03:14,454
对不对
73
00:03:14,454 --> 00:03:16,469
这时候B就变成了父亲
74
00:03:16,469 --> 00:03:17,880
C就变成儿子了
75
00:03:18,660 --> 00:03:20,820
所以，这个派生呢只是一个
76
00:03:21,110 --> 00:03:21,833
关系
77
00:03:21,833 --> 00:03:23,520
或者只是一个角色
78
00:03:24,010 --> 00:03:25,606
不是说你就是派生
79
00:03:25,606 --> 00:03:26,493
你就是儿子
80
00:03:26,493 --> 00:03:27,380
81
00:03:27,800 --> 00:03:30,227
你在和他的关系中扮演儿子
82
00:03:30,227 --> 00:03:33,060
但是你在和他的关系中扮演父亲
83
00:03:33,500 --> 00:03:33,683
84
00:03:33,683 --> 00:03:35,155
它只是一个角色
85
00:03:35,155 --> 00:03:36,810
结果他把它放到这个
86
00:03:37,510 --> 00:03:39,376
这个上面来，不用的
87
00:03:39,376 --> 00:03:41,710
你就说排空残渣就行了
88
00:03:41,710 --> 00:03:42,410
这里
89
00:03:43,150 --> 00:03:45,628
派生这个就已经说明问题了
90
00:03:45,628 --> 00:03:47,344
你这里给一个派生
91
00:03:47,344 --> 00:03:49,060
相当于把那个角色给
92
00:03:49,460 --> 00:03:51,490
移到那个
93
00:03:51,850 --> 00:03:52,813
名称上来了
94
00:03:52,813 --> 00:03:53,970
这个不对的
95
00:03:58,870 --> 00:03:59,860
第二个
96
00:04:00,160 --> 00:04:02,410
这个词尽量要统一
97
00:04:02,750 --> 00:04:03,014
98
00:04:03,014 --> 00:04:07,250
但是这也是我们很多做需求的人
99
00:04:08,500 --> 00:04:10,310
经常出现的问题
100
00:04:10,630 --> 00:04:12,470
因为他说的是废话
101
00:04:13,410 --> 00:04:15,000
但是呢，他为了
102
00:04:16,190 --> 00:04:18,363
掩盖自己说的废话
103
00:04:18,363 --> 00:04:19,450
他故意换词
104
00:04:19,940 --> 00:04:20,670
你看
105
00:04:20,950 --> 00:04:22,810
这里用排空残渣
106
00:04:25,720 --> 00:04:26,680
这里呢
107
00:04:27,400 --> 00:04:29,300
这是排空残渣
108
00:04:29,300 --> 00:04:31,200
这是残渣移除
109
00:04:33,170 --> 00:04:34,952
这两个有什么区别吗
110
00:04:34,952 --> 00:04:35,348
没有
111
00:04:35,348 --> 00:04:35,546
112
00:04:35,546 --> 00:04:36,932
但是他通过换词
113
00:04:36,932 --> 00:04:37,922
换了一个词
114
00:04:37,922 --> 00:04:39,110
好像有个创新
115
00:04:39,970 --> 00:04:40,166
116
00:04:40,166 --> 00:04:42,135
但这个是没有必要的
117
00:04:42,135 --> 00:04:44,300
但我们经常很多人拿这个
118
00:04:44,920 --> 00:04:47,560
换一个近义词
119
00:04:48,640 --> 00:04:51,848
好像我做了进一步思考了
120
00:04:51,848 --> 00:04:52,450
比如说
121
00:04:52,880 --> 00:04:54,240
我们前面也讲过
122
00:04:54,240 --> 00:04:55,090
取款机是吧
123
00:04:55,620 --> 00:04:56,950
取款机
124
00:04:57,230 --> 00:04:57,506
125
00:04:57,506 --> 00:04:59,720
为什么有取款机
126
00:04:59,720 --> 00:05:02,210
因为他要取款
127
00:05:02,500 --> 00:05:04,045
为什么要取款呢
128
00:05:04,045 --> 00:05:05,370
因为他要取钱
129
00:05:05,650 --> 00:05:06,270
130
00:05:07,350 --> 00:05:14,458
因为他需要用到现金
131
00:05:14,458 --> 00:05:15,880
反正就是
132
00:05:16,170 --> 00:05:17,340
就说来说去
133
00:05:17,340 --> 00:05:20,148
就是车轱辘话，换了几个词
134
00:05:20,148 --> 00:05:22,020
像这种，我们要警惕
135
00:05:22,300 --> 00:05:23,339
这个的话
136
00:05:23,339 --> 00:05:26,042
我在我写的那个系列文章里面
137
00:05:26,042 --> 00:05:27,289
伪创新
138
00:05:27,289 --> 00:05:28,537
批评领域驱动设计
139
00:05:28,537 --> 00:05:31,240
伪创新文章里面
140
00:05:32,040 --> 00:05:34,000
经常提到这个问题
141
00:05:34,430 --> 00:05:36,510
伪创新经常用什么
142
00:05:36,790 --> 00:05:37,940
换词
143
00:05:39,620 --> 00:05:40,287
然后呢
144
00:05:40,287 --> 00:05:42,290
叠词，就把几个词并在
145
00:05:42,570 --> 00:05:45,180
并在一起，叠词
146
00:05:46,340 --> 00:05:48,000
或者改变词序
147
00:05:48,590 --> 00:05:50,500
比如说，这个排空残渣
148
00:05:51,340 --> 00:05:53,595
再来一个残渣排空
149
00:05:53,595 --> 00:05:54,158
150
00:05:54,158 --> 00:05:55,850
调换那个词序
151
00:05:56,800 --> 00:05:59,040
但实际上这种就是废话来着
152
00:05:59,850 --> 00:06:01,290
我们要了解这一点
153
00:06:02,620 --> 00:06:04,877
实际上这里面移除
154
00:06:04,877 --> 00:06:06,520
用了一个新词
155
00:06:06,800 --> 00:06:07,050
156
00:06:07,050 --> 00:06:08,300
没有必要
157
00:06:08,880 --> 00:06:10,250
我们要尽量统一
158
00:06:10,250 --> 00:06:11,450
我们的用语
159
00:06:13,910 --> 00:06:14,229
好
160
00:06:14,229 --> 00:06:18,700
那下面，我们就来添加上这个图了
这篇关于什么是系统工程（字幕）26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！
