The results show that the quaternary ammonium cations C12 TA(superscript + and C14 TA(superscript +) with short alkyl chain only react with the hydration cation in the interlamerllar space of hydrobiotite, while those with long chain C16 TA(superscript + and C18 TA(superscript +) first react with the hydration cation, then with the kalium cation in phlogopite interlayer.

结果表明：较短链长的季铵盐阳离子C12TA(上标+， C14TA只与水黑云母蛭石晶层中的水合阳离子发生反应；而长链季铵盐阳离子C16TA(上标+， C18TA先同蛭石晶层的水合阳离子交换反应，再与云母晶层中的钾离子发生交换反应。

We used two different intercalation agents to treat clay:the phosphonium saltand the ammonium salt.

我们使用两种不同的插层剂改质黏土：磷盐与胺盐。将黏土预先在水中分散后再用插层剂进行插层。

The purpose of this paper is to synthesize some phosphonium salts with PPh3 and some chiral quaternary ammonium salts with L-Valine. And we also use L-Valine and L-Phe-OMe to synthesize a new type catalyst —2,5-diketopiperazine , the simplest compound of cyclo-peptide.

本文利用廉价易得的三苯基磷和手性L-缬氨酸作为起始原料，合成了几种普通季鏻盐和手性季铵盐，并且利用L-缬氨酸与L-苯丙氨酸甲酯反应，合成了一种新型的相转移催化剂——2，5-二酮哌嗪环类的化合物。

The result shows that the primary cause producing pockmark is low quality heating salt and nsuitble deoxizing operations,high oxygen po tential during salt-ath heat treatm et,or nonhomogeneous protective atomosphere in furnace when carburizing or dual-eating gears and SO on,which all belong to corrosions caused by in complete oxidation.

结果表明，"麻点"产生的主要原因是因为盐浴热处理时加热盐的质量和脱氧操作不当、齿轮渗碳或二次加热时炉内保护气氛氧势高或不均匀及炉罐漏气等，它们都属于不完全氧化所产生的腐蚀。

Based on a lot of experiments, the polarizable effect of water is considered as the main reason for the voltage distribution of insulator of HVDC transmission lines, and not only the salt density.

对于直流绝缘子表面电位分布的解释，传统的解释为由于盐密的影响和电导的作用。通过大量的实验总结，认为起主要作用的是水的极化作用，其中不只是盐密电导的作用。

This kind of organic salts can polymerize under peroxide radicals forming poly-salt particles that impart reinforcing effect to elastomer.

不饱和羧酸盐用于橡胶的补强是20世纪80年代末兴起的新型橡胶补强方法，这种有机盐在过氧化物作用下生成了聚盐粒子发挥了补强作用。

The results show that the tiller number, biomass accumulation, contents of soluble sugar and proline, and activity of SOD isozyme of E+ plants were significantly higher (P.05), but malondialdehyde content significantly lower (P.05), than those of F- plants. In conclusion, endophyte infection improved the salt tolerance of wild barley under outside pot conditions.

结果表明：在高盐浓度300 mmol L^(-1下内生真菌显著提高了宿主野大麦分蘖能力、生物量积累、可溶性糖含量、脯氨酸含量、SOD酶活性(P.05)，同时降低了丙二醛含量，说明内生真菌的侵入有利于提高宿主野大麦在室外盆栽条件下的耐盐性。
