Test box
检测盒───Test box
E – light aperture center to inside of test box.───电灯开口中心到测试箱的内部.
proved by FEM analysis that the proposed shape and structure of the test box can avoid resonance with the model soil.───在选定模型箱结构的外形与构造时，借助有限元分析论证了可不与模型土发生共振的箱体构造；
There are several ways in students operation: link circuit on test box; weld circuit on schematic panel, and this paper emphasizes on the latter one.───学生实践操作的方法有：实验箱上搭接电路和在印刷板上焊接电路，并重点介绍了后一种方法。
This paper introduces a optimum seeking design method for high - low temperature test - box.───介绍了一种高低温试验箱的优化设计方法.
H – top of lamp housing to inside of test box.───电灯外壳的顶部到测试箱的内部.
G – luminaire height ( bottom inside of test box to top of permanently attached parts ).───灯具高度 ( 测试箱内底部到永久附件之间的距离 ).
Methods: 7 common-used nonmetal materials were burned in the combustion test box; and qualitative analysis was done by detective apparatus and GC-MS.───方法：将7种常用非金属材料在燃烧试验箱中燃烧，用检测仪器和GC - MS进行定性分析。
