可靠性筛选 meaning in English

reliability screening

All fiber channels , fiber interface components is chosen and filtered by abortive method
所有光路，光纤接口经过精心选型，可靠性筛选等措施。
We find that there usually exist peaks in the electric derivative curve and optic derivative curve of high power semiconductor laser , these two kinds of peaks are related properly , the peaks with reliability of device . while the peaks with relation with the reliability of device , while the peaks with same direction are usually related to the inner defects , same directin are usually related to the inner defects , carrier leakage and current leakage , so , the device with same direction peaks is usually unreliable one
( 2 ) m 、 h值大， b值小的器件是质量和可靠性不好的器件( 3 )导数曲线上的峰与光导数曲线上的峰相对应，反向峰通常与器件的可靠性无关，而同向峰的存在于器件的质量和可靠性密切相关，有同向峰的器件通常是质量不好的器件，这类器件老化后特性明显变差，这意味着导数曲线上的同向峰可以作为高功率半导体激光器可靠性筛选的一个辅助判据。
