什么是系统工程（字幕）05

58
00:02:44,727 --> 00:02:46,290
首先我们把

59
00:02:47,620 --> 00:02:50,350
建模工具的布局说一下

60
00:02:51,500 --> 00:02:52,990
这个浏览器

61
00:02:54,300 --> 00:02:55,932
本来你安装好之后

62
00:02:55,932 --> 00:02:57,973
它本来在左边这边的

63
00:02:57,973 --> 00:03:00,218
我现在把它调到右边来

64
00:03:00,218 --> 00:03:03,280
我习惯的，或者我推荐的做法是

65
00:03:03,560 --> 00:03:04,490
在这里

66
00:03:05,040 --> 00:03:05,993
都可以拖动

67
00:03:05,993 --> 00:03:07,710
把它摆在

68
00:03:07,990 --> 00:03:09,007
各自的位置

69
00:03:09,007 --> 00:03:10,228
浏览器在这里

70
00:03:10,228 --> 00:03:12,060
然后属性框在这里

71
00:03:12,360 --> 00:03:14,170
工具箱在这里

72
00:03:17,840 --> 00:03:19,860
那在往下建模之前

73
00:03:20,930 --> 00:03:23,070
我们要调整一下

74
00:03:23,590 --> 00:03:26,896
我们建模环境的字体

75
00:03:26,896 --> 00:03:27,369
字体

76
00:03:27,369 --> 00:03:28,786
包括颜色等等

77
00:03:28,786 --> 00:03:30,676
因为调好看一点的话

78
00:03:30,676 --> 00:03:32,329
你模型好看一点

79
00:03:32,329 --> 00:03:35,400
所以呢，我们这里调一下

80
00:03:40,800 --> 00:03:44,400
首先，主题这里，我们就用这个

81
00:03:46,590 --> 00:03:49,275
单色主题，黑白就行了

82
00:03:49,275 --> 00:03:53,181
其他花花绿绿，不喜欢

83
00:03:53,181 --> 00:03:53,670
因为

84
00:03:54,030 --> 00:03:55,120
我们

85
00:03:56,460 --> 00:03:58,310
后面那个

86
00:03:58,590 --> 00:04:01,424
教材上的图就是黑白的嘛

87
00:04:01,424 --> 00:04:01,940
对吧

88
00:04:05,550 --> 00:04:06,530
黑白的

89
00:04:08,030 --> 00:04:08,634
然后呢

90
00:04:08,634 --> 00:04:09,842
字体在这里（口误）

91
00:04:09,842 --> 00:04:11,452
这个已经挑好了

92
00:04:11,452 --> 00:04:13,667
就选这个就行

93
00:04:13,667 --> 00:04:14,875
如果不是的话

94
00:04:14,875 --> 00:04:16,083
可以改成这个

95
00:04:16,083 --> 00:04:18,096
当然，如果你喜欢花花绿绿

96
00:04:18,096 --> 00:04:20,110
你可以选其中某一个

97
00:04:20,390 --> 00:04:21,260
自己挑

98
00:04:21,960 --> 00:04:23,250
然后是字体

99
00:04:24,930 --> 00:04:27,523
这里，元素的字体

100
00:04:27,523 --> 00:04:28,820
这里，默认

101
00:04:29,470 --> 00:04:29,726

102
00:04:29,726 --> 00:04:31,780
我们可以把它改成

103
00:04:32,650 --> 00:04:35,060
好看一点的字体，微软雅黑

104
00:04:35,340 --> 00:04:35,541

105
00:04:35,541 --> 00:04:36,345
大一点

106
00:04:36,345 --> 00:04:37,350
14号

107
00:04:38,580 --> 00:04:39,500
这样来

108
00:04:42,360 --> 00:04:44,140
微软雅黑14号

109
00:04:44,510 --> 00:04:45,190
这样来

110
00:04:45,690 --> 00:04:45,873

111
00:04:45,873 --> 00:04:47,895
只要调这两个就行了

112
00:04:47,895 --> 00:04:48,630
一个这个

113
00:04:50,040 --> 00:04:51,560
一个这个字体

114
00:04:56,960 --> 00:04:57,850
好

115
00:04:58,720 --> 00:05:00,010
那首先呢

116
00:05:00,290 --> 00:05:01,760
我们就要来

117
00:05:02,920 --> 00:05:04,510
给它建一个

118
00:05:05,010 --> 00:05:05,986
包了

119
00:05:05,986 --> 00:05:08,590
我们给它建一个包

120
00:05:13,900 --> 00:05:15,400
我们的那个

121
00:05:16,670 --> 00:05:17,620
根目录的包

122
00:05:17,620 --> 00:05:18,570
我们可以叫

123
00:05:21,140 --> 00:05:22,540
你看我们这个

124
00:05:23,040 --> 00:05:24,679
这个包图嘛，对吧

125
00:05:24,679 --> 00:05:27,724
这个包图叫蒸馏器模型，对吧

126
00:05:27,724 --> 00:05:29,130
那我们这个就照搬

127
00:05:29,410 --> 00:05:32,040
蒸馏器

128
00:05:35,180 --> 00:05:36,170
模型

129
00:05:38,080 --> 00:05:38,295

130
00:05:38,295 --> 00:05:41,100
这里面叫项目，蒸馏器项目

131
00:05:42,900 --> 00:05:43,145

132
00:05:43,145 --> 00:05:43,880
在这里

133
00:05:45,030 --> 00:05:45,735
然后呢

134
00:05:45,735 --> 00:05:46,910
在这下面呢

135
00:05:47,820 --> 00:05:49,595
你看，它有这么几个包

136
00:05:49,595 --> 00:05:51,370
那这几个包，我们来把它

137
00:05:54,700 --> 00:05:56,538
中文翻译一下

138
00:05:56,538 --> 00:05:57,851
蒸馏器需求

139
00:05:57,851 --> 00:06:01,790
蒸馏器用例、蒸馏器行为、蒸馏器结构

140
00:06:02,170 --> 00:06:05,034
项类型、值类型、工程分析

141
00:06:05,034 --> 00:06:07,040
还有一个ISO 80000

142
00:06:07,740 --> 00:06:08,120

143
00:06:08,120 --> 00:06:09,640
80000

144
00:06:13,300 --> 00:06:16,016
当然，像这个前面都带一个蒸馏器

145
00:06:16,016 --> 00:06:18,151
这个显然有点废话

146
00:06:18,151 --> 00:06:18,927
可以删掉

147
00:06:18,927 --> 00:06:19,510
但是呢

148
00:06:20,220 --> 00:06:23,640
我们为了尊重原来的教程

149
00:06:23,970 --> 00:06:25,657
我们就不删了

150
00:06:25,657 --> 00:06:26,970
直接按照这个来

151
00:06:27,380 --> 00:06:31,180
那这有个项类型，item这个

152
00:06:32,060 --> 00:06:34,760
这个项，这里指的是那个

153
00:06:35,140 --> 00:06:37,166
将来我们要用到的

154
00:06:37,166 --> 00:06:38,180
比如说，在

155
00:06:38,460 --> 00:06:39,520
两个

156
00:06:40,070 --> 00:06:42,960
block之间传递

157
00:06:43,310 --> 00:06:45,250
信息的，通过流

158
00:06:45,530 --> 00:06:45,814

159
00:06:45,814 --> 00:06:48,090
端口流进来，流出来

160
00:06:48,370 --> 00:06:50,340
那流入（流出）的那个东西

161
00:06:50,690 --> 00:06:51,004

162
00:06:51,004 --> 00:06:52,260
我们叫项

163
00:06:53,960 --> 00:06:56,760
主要用来表达类似这样的东西

164
00:06:57,470 --> 00:07:00,117
但这里我们叫项，不叫数据项

165
00:07:00,117 --> 00:07:02,562
因为我们做的不是信息系统

166
00:07:02,562 --> 00:07:05,210
它流动的不是数据

167
00:07:05,210 --> 00:07:06,432
它可能是水流

168
00:07:06,432 --> 00:07:07,450
可能是热流

169
00:07:07,450 --> 00:07:08,672
可能是电流

170
00:07:08,672 --> 00:07:09,080
对吧

171
00:07:09,800 --> 00:07:10,673
不是数据流

172
00:07:10,673 --> 00:07:12,246
如果你做的是信息系统

173
00:07:12,246 --> 00:07:13,120
那是数据流

174
00:07:15,240 --> 00:07:15,980
这个

175
00:07:17,410 --> 00:07:20,074
那下一个是工程分析

176
00:07:20,074 --> 00:07:21,850
这个包呢，主要是放

177
00:07:22,310 --> 00:07:23,640
一些那个

178
00:07:24,020 --> 00:07:25,600
分析性能的

179
00:07:26,370 --> 00:07:26,682

180
00:07:26,682 --> 00:07:28,555
包括约束块

181
00:07:28,555 --> 00:07:31,364
包括我们的参数图

182
00:07:31,364 --> 00:07:33,550
参数模型，等等

183
00:07:36,130 --> 00:07:41,664
那么这个ISO 80000，就是外部的一个模型库了

184
00:07:41,664 --> 00:07:43,830
要导进来的

185
00:07:44,580 --> 00:07:49,580
ISO量和单位的，定义好的一些标准

186
00:07:51,890 --> 00:07:53,130
一个模型库

187
00:07:53,460 --> 00:07:55,060
我们把它导进来

188
00:07:56,650 --> 00:07:59,142
那首先呢，我们就来操作一下

189
00:07:59,142 --> 00:08:01,220
就是，怎样来导入这个

190
00:08:01,880 --> 00:08:03,530
ISO这个库
