0
00:00:00,670 --> 00:00:01,582
如果不加图

1
00:00:01,582 --> 00:00:02,130
怎么加

2
00:00:02,130 --> 00:00:03,225
我们来看一下

3
00:00:03,225 --> 00:00:03,590
你看

4
00:00:03,980 --> 00:00:06,720
右键点这个，添加元素

5
00:00:07,380 --> 00:00:07,960

6
00:00:08,500 --> 00:00:09,800
这里选

7
00:00:10,400 --> 00:00:13,100
系统工程，SysML

8
00:00:13,480 --> 00:00:13,781

9
00:00:13,781 --> 00:00:17,700
然后SysML 1.5，块定义

10
00:00:18,000 --> 00:00:18,167

11
00:00:18,167 --> 00:00:20,005
这里默认就已经是block了

12
00:00:20,005 --> 00:00:22,010
那我们首先加第一个是什么

13
00:00:22,860 --> 00:00:23,620
这个

14
00:00:27,300 --> 00:00:29,150
蒸馏器系统上下文

15
00:00:30,570 --> 00:00:33,820
直接敲蒸馏器系统

16
00:00:34,540 --> 00:00:35,920
上下文

17
00:00:39,420 --> 00:00:41,080
你看，这就多了一个

18
00:00:41,080 --> 00:00:41,495
对吧

19
00:00:41,495 --> 00:00:42,948
然后可以继续加

20
00:00:42,948 --> 00:00:44,608
你看那个界面还在

21
00:00:44,608 --> 00:00:45,231
对不对

22
00:00:45,231 --> 00:00:47,722
我们一个一个加，水源，蒸馏器

23
00:00:47,722 --> 00:00:49,174
水分配系统，热源

24
00:00:49,174 --> 00:00:49,590
对吧

25
00:00:50,270 --> 00:00:52,420
水源

26
00:00:56,010 --> 00:00:57,390
蒸馏器

27
00:00:59,320 --> 00:01:02,160
水分配系统

28
00:01:08,830 --> 00:01:10,130
热源

29
00:01:12,970 --> 00:01:13,220
好

30
00:01:13,220 --> 00:01:13,970
还有吗

31
00:01:13,970 --> 00:01:14,720
我看看

32
00:01:15,520 --> 00:01:17,100

33
00:01:17,730 --> 00:01:18,078

34
00:01:18,078 --> 00:01:19,470
就这几个

35
00:01:20,060 --> 00:01:20,392
好

36
00:01:20,392 --> 00:01:23,720
这是这几个结点上那个block了

37
00:01:24,020 --> 00:01:28,291
也就是说，结点上这个block每个代表一个什么

38
00:01:28,291 --> 00:01:29,640
代表一个系统

39
00:01:29,640 --> 00:01:30,090
对吧

40
00:01:30,370 --> 00:01:31,470
所以这个

41
00:01:32,140 --> 00:01:36,136
块内部图的抽象级别是在什么级别

42
00:01:36,136 --> 00:01:39,910
它是系统之间的交互

43
00:01:44,340 --> 00:01:44,654
好

44
00:01:44,654 --> 00:01:45,910
这里没了

45
00:01:47,070 --> 00:01:50,190
那接下来，就来加这个了

46
00:01:50,650 --> 00:01:52,630
中间这个流动

47
00:01:52,630 --> 00:01:53,950
这个热、水

48
00:01:53,950 --> 00:01:54,610
这个

49
00:01:56,280 --> 00:01:58,772
你看，这后面是类

50
00:01:58,772 --> 00:02:01,014
这后面是那个类

51
00:02:01,014 --> 00:02:02,510
或者类元，这是那个

52
00:02:03,060 --> 00:02:05,028
实例的名字，对吧

53
00:02:05,028 --> 00:02:05,310

54
00:02:05,310 --> 00:02:07,278
冒号右边是类型

55
00:02:07,278 --> 00:02:08,403
左边实例

56
00:02:08,403 --> 00:02:09,810
所以我们是

57
00:02:10,130 --> 00:02:10,990
先

58
00:02:11,490 --> 00:02:12,595
加这个类型

59
00:02:12,595 --> 00:02:13,921
一个水，一个热

60
00:02:13,921 --> 00:02:15,911
后面什么污水净水呀

61
00:02:15,911 --> 00:02:17,680
这个是它的那个

62
00:02:18,190 --> 00:02:19,670
实例的名字

63
00:02:19,950 --> 00:02:22,250
或者说，角色的名字

64
00:02:24,050 --> 00:02:24,997
加在哪里

65
00:02:24,997 --> 00:02:27,130
那这个是放在值类型

66
00:02:28,670 --> 00:02:30,390
这个包这里

67
00:02:32,440 --> 00:02:33,890
这里我们可以

68
00:02:35,000 --> 00:02:37,153
添加两个block，一样的

69
00:02:37,153 --> 00:02:38,349
跟刚才一样

70
00:02:38,349 --> 00:02:40,742
你可以不用画图都可以

71
00:02:40,742 --> 00:02:40,981

72
00:02:40,981 --> 00:02:41,460
添加

73
00:02:41,740 --> 00:02:42,790
一个是

74
00:02:43,070 --> 00:02:44,020
水

75
00:02:49,420 --> 00:02:50,620
一个是热

76
00:02:54,770 --> 00:02:55,570
好

77
00:02:56,470 --> 00:02:57,790
这两个有了

78
00:03:01,690 --> 00:03:03,190
那接下来

79
00:03:03,900 --> 00:03:05,793
就是要画这个图了

80
00:03:05,793 --> 00:03:07,450
你看，这个图是什么

81
00:03:08,420 --> 00:03:13,470
这个蒸馏器系统上下文这个block的什么

82
00:03:13,750 --> 00:03:16,570
IBD，就是内部块图

83
00:03:17,790 --> 00:03:19,050
它名字叫

84
00:03:19,630 --> 00:03:21,650
context，上下文

85
00:03:22,400 --> 00:03:23,240
这是它的名字

86
00:03:23,240 --> 00:03:24,753
那我们就来画一下

87
00:03:24,753 --> 00:03:25,090
你看

88
00:03:26,110 --> 00:03:28,570
针对这个上下文

89
00:03:29,220 --> 00:03:30,048
画图嘛

90
00:03:30,048 --> 00:03:31,430
右键点它

91
00:03:31,970 --> 00:03:34,040
添加一个这个

92
00:03:35,180 --> 00:03:35,860
对吧

93
00:03:36,140 --> 00:03:37,270
添加这个

94
00:03:38,460 --> 00:03:38,756

95
00:03:38,756 --> 00:03:40,830
图的名字，上下文

96
00:03:44,360 --> 00:03:45,812
怎么1.4

97
00:03:45,812 --> 00:03:47,103
我们不要1.4

98
00:03:47,103 --> 00:03:47,910
我们1.5

99
00:03:48,230 --> 00:03:49,310
添加

100
00:03:49,880 --> 00:03:51,530
添加图

101
00:03:51,870 --> 00:03:53,070
然后呢

102
00:03:53,070 --> 00:03:53,870
这个

103
00:03:56,060 --> 00:03:57,320
SysML

104
00:03:57,910 --> 00:03:58,900
1.5

105
00:03:59,560 --> 00:04:00,180

106
00:04:01,230 --> 00:04:02,030
这个

107
00:04:02,470 --> 00:04:04,370
然后改名叫上下文

108
00:04:07,890 --> 00:04:08,157
好

109
00:04:08,157 --> 00:04:10,560
你看，对应一下这个

110
00:04:11,570 --> 00:04:13,410
IBD block 

111
00:04:13,850 --> 00:04:15,930
蒸馏器系统上下文，上下文

112
00:04:16,760 --> 00:04:20,113
IBD block，蒸馏器系统上下文

113
00:04:20,113 --> 00:04:20,831
对吧

114
00:04:20,831 --> 00:04:21,310
好

115
00:04:21,310 --> 00:04:21,790
接下来，我们就要来

116
00:04:23,830 --> 00:04:25,020
把这些

117
00:04:25,790 --> 00:04:27,210
放上去了

118
00:04:27,720 --> 00:04:29,740
那这些浏览器里都有了嘛

119
00:04:29,740 --> 00:04:30,144
对吧

120
00:04:30,144 --> 00:04:31,760
我们就把它拖上来

121
00:04:35,010 --> 00:04:36,270
第一个要拖的

122
00:04:36,270 --> 00:04:37,110
就是那个

123
00:04:38,140 --> 00:04:39,170
水源

124
00:04:39,530 --> 00:04:41,340
这里，拖上来

125
00:04:42,990 --> 00:04:47,269
然后这里选property，表示这是它的一个属性

126
00:04:47,269 --> 00:04:49,623
它默认就property，属性

127
00:04:49,623 --> 00:04:51,120
还有其他选项

128
00:04:51,120 --> 00:04:52,618
先不用管它

129
00:04:52,618 --> 00:04:54,116
就这个，属性

130
00:04:54,116 --> 00:04:55,186
实际上这一步

131
00:04:55,186 --> 00:04:56,470
跟我们在那个

132
00:04:57,750 --> 00:05:00,454
块定义图里面画那个组合关系

133
00:05:00,454 --> 00:05:01,910
是一样的

134
00:05:02,190 --> 00:05:04,836
只不过我们这里没有画那个块定义图组合关系

135
00:05:04,836 --> 00:05:06,160
如果你画了组合关系

136
00:05:07,020 --> 00:05:10,240
说我这个上下文组合了一个水源

137
00:05:10,900 --> 00:05:12,100
那么这个

138
00:05:12,510 --> 00:05:15,995
上下文这里，你看，这里就出现一个属性嘛

139
00:05:15,995 --> 00:05:16,815
你看

140
00:05:16,815 --> 00:05:17,020

141
00:05:17,020 --> 00:05:20,095
你在块定义图里面画一个组合关系

142
00:05:20,095 --> 00:05:22,145
它也可以起到这个效果

143
00:05:22,145 --> 00:05:23,990
它也是一个属性

144
00:05:24,560 --> 00:05:26,786
因为我没有画块定义图嘛

145
00:05:26,786 --> 00:05:28,608
我们直接在块内部图

146
00:05:28,608 --> 00:05:31,240
内部块图这里操作了

147
00:05:32,270 --> 00:05:35,299
所以这里，那这个名字就不要了

148
00:05:35,299 --> 00:05:36,380
这名字不要

149
00:05:36,380 --> 00:05:37,030
因为它

150
00:05:39,350 --> 00:05:41,937
那个图上这里就没有名字嘛

151
00:05:41,937 --> 00:05:42,335
对吧

152
00:05:42,335 --> 00:05:43,530
这里没有名字

153
00:05:43,990 --> 00:05:47,040
左边这个实例名没有

154
00:05:47,440 --> 00:05:50,820
还有，接下来，下一个就是那个蒸馏器

155
00:05:55,620 --> 00:05:57,300
也同样不要名字

156
00:05:59,620 --> 00:06:00,630
还有什么

157
00:06:01,350 --> 00:06:02,670
水分配系统

158
00:06:12,110 --> 00:06:13,865
还有操作人员

159
00:06:13,865 --> 00:06:16,280
那从用例那里拖过来了

160
00:06:16,600 --> 00:06:17,420
放这里

161
00:06:26,380 --> 00:06:28,670
还有什么，热源

162
00:06:39,530 --> 00:06:43,100
还有一个小人是用水人员

163
00:06:50,970 --> 00:06:52,070
这样

164
00:06:52,350 --> 00:06:54,150
我们对齐一下

165
00:07:09,700 --> 00:07:10,730
小一点

166
00:07:11,530 --> 00:07:11,822
好

167
00:07:11,822 --> 00:07:12,990
往下一点

168
00:07:48,280 --> 00:07:49,220
好

169
00:07:50,080 --> 00:07:51,130
这样来

170
00:07:52,000 --> 00:07:55,290
那接下来，你看，这里有一个

171
00:07:55,850 --> 00:07:56,793
多重性

172
00:07:56,793 --> 00:07:59,386
表示这个属性的多重性

173
00:07:59,386 --> 00:08:00,330
这个得先

174
00:08:00,820 --> 00:08:02,100
设置了

175
00:08:04,390 --> 00:08:05,201
那多重性在哪里设置

176
00:08:05,201 --> 00:08:07,230
就选中这个

177
00:08:09,170 --> 00:08:12,010
然后在property这里

178
00:08:12,410 --> 00:08:13,090

179
00:08:13,630 --> 00:08:14,945
然后往下走

180
00:08:14,945 --> 00:08:16,260
你看有多重性

181
00:08:17,930 --> 00:08:20,094
然后这个是多少来着

182
00:08:20,094 --> 00:08:21,297
一到多，对吧

183
00:08:21,297 --> 00:08:22,740
所以下限是1

184
00:08:23,190 --> 00:08:24,820
上限是多

185
00:08:27,650 --> 00:08:28,270

186
00:08:29,340 --> 00:08:29,583

187
00:08:29,583 --> 00:08:31,528
你看，这就出来了

188
00:08:31,528 --> 00:08:33,230
这个呢，是多少

189
00:08:33,510 --> 00:08:36,750
这是0到多

190
00:08:37,740 --> 00:08:39,195
下限是0

191
00:08:39,195 --> 00:08:40,650
上限是多

192
00:08:42,880 --> 00:08:43,154

193
00:08:43,154 --> 00:08:44,250
这样来

194
00:08:44,880 --> 00:08:46,005
搞小一点

195
00:08:46,005 --> 00:08:47,580
这个太大了

196
00:08:57,930 --> 00:08:59,150
下面也是一样

197
00:08:59,860 --> 00:09:00,061

198
00:09:00,061 --> 00:09:01,070
都搞小一点

199
00:09:12,430 --> 00:09:12,846
好

200
00:09:12,846 --> 00:09:14,510
这搞定了

201
00:09:15,310 --> 00:09:17,355
但是这里有个小人

202
00:09:17,355 --> 00:09:19,401
这个就搞不定了

203
00:09:19,401 --> 00:09:20,310
这搞不定

204
00:09:20,310 --> 00:09:21,220
因为那个

205
00:09:21,710 --> 00:09:22,801
这里没有小人

206
00:09:22,801 --> 00:09:24,257
你要小人可以

207
00:09:24,257 --> 00:09:25,531
你把小人拖上来

208
00:09:25,531 --> 00:09:26,440
你看怎么做

209
00:09:26,440 --> 00:09:28,260
如果你不想要这个

210
00:09:28,260 --> 00:09:29,534
你想要小人呢

211
00:09:29,534 --> 00:09:30,080
拖上来

212
00:09:30,520 --> 00:09:30,723

213
00:09:30,723 --> 00:09:33,159
但这里就不要Property了

214
00:09:33,159 --> 00:09:34,580
这里选实例

215
00:09:34,940 --> 00:09:35,670
这里

216
00:09:36,740 --> 00:09:37,836
这样可以

217
00:09:37,836 --> 00:09:39,590
但是这样可以的话

218
00:09:39,590 --> 00:09:42,880
这边就没有这个方框了

219
00:09:44,260 --> 00:09:47,460
所以我们这里，这小人就不管它了

220
00:09:51,410 --> 00:09:51,686
好

221
00:09:51,686 --> 00:09:53,900
接下来呢，就是轮到

222
00:09:54,630 --> 00:09:57,750
各个block之间的那个

223
00:09:58,590 --> 00:10:01,140
应该说各个属性之间的那个

224
00:10:01,750 --> 00:10:02,630
关系了

225
00:10:02,630 --> 00:10:03,510
那个连接

226
00:10:03,510 --> 00:10:06,810
那这里面的连接，实际上就一个，就是那个

227
00:10:08,750 --> 00:10:14,981
项，item的这个流，item这个流的关系

228
00:10:14,981 --> 00:10:17,813
实际上是一种动态的关系

229
00:10:17,813 --> 00:10:18,380
我有

230
00:10:19,140 --> 00:10:20,910
水流到你那里

231
00:10:22,700 --> 00:10:24,130
那这个怎么画

232
00:10:25,310 --> 00:10:28,047
我们的那个水、热是在哪里

233
00:10:28,047 --> 00:10:29,415
水、热在这里嘛

234
00:10:29,415 --> 00:10:29,871
对吧

235
00:10:29,871 --> 00:10:30,100

236
00:10:32,430 --> 00:10:33,673
然后画过来

237
00:10:33,673 --> 00:10:37,653
显然这个三角这个，就是哪一个

238
00:10:37,653 --> 00:10:38,400
就这个

239
00:10:39,390 --> 00:10:43,010
项流这个，你看怎么画

240
00:10:43,010 --> 00:10:44,820
选中这个，画过来

241
00:10:46,150 --> 00:10:46,800

242
00:10:47,080 --> 00:10:48,520
然后添加

243
00:10:48,960 --> 00:10:50,588
我们是水嘛

244
00:10:50,588 --> 00:10:51,240
对吧

245
00:10:51,950 --> 00:10:52,770
确定

246
00:10:53,170 --> 00:10:54,920
然后这里添加上这个

247
00:10:58,370 --> 00:10:58,598
好

248
00:10:58,598 --> 00:10:59,738
这样过来

249
00:10:59,738 --> 00:11:01,334
我把它过来一点

250
00:11:01,334 --> 00:11:01,562

251
00:11:01,562 --> 00:11:02,930
有点窄了

252
00:11:06,850 --> 00:11:07,152
好

253
00:11:07,152 --> 00:11:08,060
接下来

254
00:11:09,900 --> 00:11:14,340
但是这个跟我们这个图上不是一致的哦

255
00:11:15,660 --> 00:11:17,809
图上是说，你看，水是水

256
00:11:17,809 --> 00:11:19,720
它前面有个说脏水

257
00:11:20,290 --> 00:11:20,658

258
00:11:20,658 --> 00:11:22,500
也就是说，水

259
00:11:24,610 --> 00:11:25,640
是一个

260
00:11:26,000 --> 00:11:27,020
大的类型

261
00:11:27,020 --> 00:11:29,060
下面又分脏水

262
00:11:29,530 --> 00:11:30,550
净水

263
00:11:31,710 --> 00:11:33,780
那这个脏水怎么表达

264
00:11:34,570 --> 00:11:34,751

265
00:11:34,751 --> 00:11:36,925
不可能说我把水改成冒号

266
00:11:36,925 --> 00:11:37,830
这不行

267
00:11:37,830 --> 00:11:39,280
另外一种就是什么

268
00:11:39,890 --> 00:11:44,330
一种做法是在这上面添加一个污水的

269
00:11:45,690 --> 00:11:46,530
Block

270
00:11:46,890 --> 00:11:49,950
它是这个水的一个

271
00:11:50,780 --> 00:11:52,470
子类

272
00:11:52,750 --> 00:11:55,420
或者子block，一个泛化关系

273
00:11:56,720 --> 00:11:56,888

274
00:11:56,888 --> 00:11:58,574
污水去继承这个水

275
00:11:58,574 --> 00:12:00,260
但这里说的不是继承

276
00:12:00,260 --> 00:12:02,790
而是说什么，冒号说的是一个实例
