The changes of the microstructure (using PAM treated with CH���COOH) and the thermal decomposition mechanism of PbO〓 electrodes during formation were first studied. The oxidation model for leady paste particles was proposed and the thermal decomposition mechanism was found to be consistent during different stages of formation.

采用CH〓COOH处理活性物质，首次研究了化成过程中PbO〓电极微观结构及热分解机理的变化，建立了铅膏粒子的氧化模型，得出化成不同阶段PbO〓热分解机理的一致性。

In the paper four strains Leu.1, Leu.2, Lact.l and Lact.2 were isolated from many sorts of pickles for their excellent characteristics in acid production and fermentation flavor. With API 50 CH system, Leu.l and Leu.2 were identified as Leuconostoc mesenteroides subsp.

本论文从多种泡菜中筛选出四株产酸较快、发酵风味好的乳酸菌Leu.1、Leu.2、Lact.1和Lact.2，经API 50 CH标准系统鉴定，Leu.1和Leu.2为肠膜明串珠菌肠膜亚种Leuconostoc mesenteroides subsp。

As the translation "song lyric" suggests, tz'u (or ch'-tzu-tz'u ,"words to songs") are verses in irregular line-lengths, often stanzaic, written—or, literally,"filled in"—so that they could be sung to existing melodies.

就宋词的译语而言，&词&，也称&曲子词&（ch'-tzu-tz'u），是一种句式参差不齐的韵文。它由不同的节填制而成，所以它是可以被用来演唱出悦耳的音调的。
