We also introduced spectrophotometer into the analysis of sulfamate type electrolete to measure the content of nickel sulfamate for the first time. This method is much easier than the conventional chemistry titration, it can be accomplished within one minute. Furthermore, it enhances significantly the precision of the measurement.

在电铸液分析中，我们首次将分光光度法应用于氨基磺酸盐型镍电铸液中氨基磺酸镍的测定，该方法较传统的化学滴定法操作更简单，它可以在1分钟内完成氨基磺酸镍浓度的测定，且大幅提高了分析结果的精确度，样品的消耗量仅为原来的千分之一。

Methods:Human CD80 cDNA was transfected into B16 melanoma cells by lipofectin-mediated gene transfer before the expansion of tumor cells were tested by MTT method in vitro;C57BL/6 mice were inculated subcutaneously either mock-transfected B16 cells (B16-neo)or CD80-transfected B16 cells (B16-CD80),then the latency,survival times and tumor mass growth were investigated.The lymphocytes were examined for both proliferation indices and specific cytotoxic activity by MTT method and improved LDH-releasing method,after syngenic Mixed Lymphocyte tumor cultures.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
