programmed pressure

The impact pressure on the surface of product and the flowing velocity were calculated by hydromechanics theory, and the calculation process was programmed by language C.

同时，运用流体力学原理，对冷却管路系统进行了理论计算，得到了喷嘴出口处的水流速度以及作用于钢板表面的冲击压力。此外，利用标准C语言对计算过程编制程序。

Based on systematical study of the response characteristics of thermal conductivity detector ( TCD) at reduced pressure, a newly designed TCD was constructed and evaluated in temperature programmed capillary gas chromatography.

根据对负压下热导检测器的响应特性与检测器参数的系统研究，研制出适用于程序升温毛细管气相色谱的热导检测器（TCD）。
