Examples
- Top quality products get a lot of word of mouth promotion , and poor quality products suffer from the same sort of word of mouth
顶尖质量的产品会得到许多达到口头促销目的的溢美之词，而质量不好的产品也会得到与它相应的评价。 - However , the tradition minutiae - matching algorithm will extract many spurious minutiae when processing fingerprint images with low quality , especially from old people . it is because some creases exist in the fingerprint . as a result , the recognition ratio will be decreased
然而对于指纹质量不好的人群如老年人群，由于在指纹中存在断纹，导致了众多虚假细节点的产生，使得识别率降低，制约了指纹识别的推广应用。 - In this paper , tio2 films as ecological self - clean glass material prepared by magnetron sputtering method were discussed in the following aspects : the preparation technology of tio2 films by magnetron sputtering method , the control of the surface microstructure , the effect of the surface microstructure on the photocatalytic activity and the optical performance of tio2 films . sem was used to observe the surface topography . xrd was used to explore the crystal form , and crystal size
为了解决以往溶胶?凝胶法制备的tio _ 2薄膜膜层质量不好的缺点，本论文对磁控溅射法在玻璃表面制备tio _ 2薄膜作为生态自洁净玻璃材料进行了一系列探索与应用基础研究，包括tio _ 2薄膜的磁控溅射法制备工艺、表面微观结构的控制、表面微观结构对tio _ 2薄膜光催化性能、透光性影响等。 - 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。
