Further more, to make the hybrid microspheres with good dispersibility in aqueous media, 3-propyl triethoxysilane was added to copolymerize with St and DVB, and after hydrolization the microspheres with silanol groups on the surface were obtained, which can be well dispersed in water and used for cell imaging.

进而将3-甲基丙烯酰氧基丙基三甲氧基硅烷作为共聚单体，得到了表面硅羟基功能化的聚苯乙烯荧光微球，改善了微球在水相中的分散性，并将此类荧光功能微球成功用于细胞成像。

Because adenine methylation does not occur endogenously in most eukaryotes, it provides a unique tag to mark protein interaction sites.

由于腺嘌呤甲基化不在大部分的真核细胞中内源性发生，它提供了一个单一的tag来标记蛋白质相互作用位点。

Gimelbrant et al. determined the proportion of human genes that can be expressed monoallelically, in patterns that are epigenetically stable (for example, chemical modifications of DNA, such as cytosine methylation, that do not alter the sequence but are heritable within cell populations).

Gimelbrant等确定部分人类基因，能够单等位基因性表达，在表达模式上，后生同类物稳定（例如，化学修饰的DNA ，如胞嘧啶甲基化，不改变序列，但内细胞群是可遗传的）。

In this paper, we analyzed the larch extract tannin, aminom ethylation of larch extract tannin, quaternization of cationic larch extract tannin and amphoteric larch extract tannin (sulfonation of the larch extract tannin quaternary ammonium) by infrared spectral analysis, confirmed the quarternization and sulfonate groups, and measured its water treatment properties such as flocculation, scale inhibition, results showed that quaternization of larch extract tannin and amphoteric larch extract tannin have better water treatment ability, can realize the multifunction.

本论文采用红外光谱法对落叶松单宁、胺甲基化落叶松单宁、阳离子落叶松单宁季胺盐、两性落叶松单宁进行了化学结构分析，并对其水处理剂性能如絮凝、阻垢进行了检测。实验结果表明：落叶松单宁季胺盐和两性落叶松单宁均具有较佳的水处理能力，是性能良好的一剂多效工业水处理剂。
