The thin film TE material resistivity measurement system which is designed in the thesis bases on the principle of four-probe method and doublepulse technology.
本论文依据四探针法的基本原理并结合双脉冲技术，设计并制造适用于薄膜温差电材料的电阻率测试系统。

Using this method, some useful conclusions have been made for analyzing orifice and double inlet pulse tube refrigerators.
将该方法运用到小孔型及双向进气型脉管制冷机的分析，得出了一些有益的结论。
