水成作用

In this paper the authors reviewed the characteristics in the different phases in the life cycle of ferns. Special attentions were given to the effect of light, plant growth regulators, water and temperature on the fern gametophyte development, and the effect of antheridiogen, light, calcium and other plant growth regulator on the formation and differentiation of fern sex organ.

作者概述了蕨类植物生活周期中不同发育阶段的特点，并着重介绍了光、植物生长调节物质、水和温度等因素对蕨类植物配子体发育的影响以及成精子囊素、光、钙离子和其它植物生长调节物质在性器官形成和分化过程中的作用。

It is suggested that the emulsify is formed when the oil on the water is stretched and stacked repeatedly by the wave, during which the water is mixed with the oil and entrain into the oil; particle asphaltene forms machinery protection film between oil and water, which stabilizes the water in the oil; the asphaltene film is formed through the accumulation when the water cohere; the resin of high viscosity can intensify the film.

通过对文献资料数据和不同观点进行分析及油水运动特点的实验观察，对溢油乳化物形成机制提出新的见解认为：乳化物是原油在波浪作用下反复拉伸和堆积中发生油水混合、水被夹带入油中而形成；颗粒态沥青质在水滴外形成机械保护膜将其稳定，它是水滴凝聚受阻时在油水界面积累而成，胶质的高粘性强化保护膜起到辅助作用。

Combining ion exchange process and silicon hydrolyze process Silicon dioxide mother nuclide with a specific particle size was prepared from sodium silicate through the dropwise technique , then the large particle size , high concentration and stable silica sol was prepared . The stability of silica sol also can be improved by enwrap .

和"单质硅一步溶解法"相结合的方法，用离子交换法制备晶种，并采用滴加工艺制备一定粒径大小的二氧化硅作为母核，在催化剂和分散剂共同作用下水解单质硅的方法使二氧化硅母核颗粒进一步增长成大粒径的二氧化硅颗粒，并另外还采用水溶性高分子对纳米SiO_2粒子进行"原位表面包覆"提高其稳定性，制备了大粒径，高浓度，稳定的纳米硅溶胶。

This dissertation aims to: improvement in regularity of ladderlike polysiloxane through strong H-bonding template and"half-water-hydrolysis"methods; synthesis of several functional polysilsequioxane with ethoxyl, hydro and aminopropyl groups respectively; and the preparation of nanoporous film with good mechanic properties from ladderlike functional polysilsesquioxane with intermolecular porogen via micro-phase separation process.

本论文旨在利用强氢键模板作用和"半水水解-脱氯化氢缩聚"的改进方法，提高反应性的梯形聚硅氧烷的规整度；合成乙氧基封端、含氢基和氨丙基的几种功能性梯形聚硅氧烷；以及探索利用含分子内成孔剂的梯形聚倍半硅氧烷通过微相分离制备低介电常数二氧化硅纳米微孔膜。

In order to test the anesthetic effect of Eugenol to Cyprinus carpio Linnaeus,Eugenol was dissolved in the water and diluted in different concentrations for the test.

为测定丁香酚对鲤Cyprinus carpioLinnaeus的麻醉作用效果，将丁香酚溶于水配制成不同浓度溶液进行试验研究。

Working principle is the power that uses water pump to serve as loop and sparge, the one side in gush room or 3 form Shui Lian, sparge is formed inside gush fog chamber, the Qi Wu of the generation when spray paint or burnish or dir

工作元理是使用水泵作为循环与喷雾的前进力，在喷房的一边或者三面产生水濂，在喷雾房内产生喷雾，喷涂或者磨擦时型成的漆雾或者尘士，在强效抽风作用以及影晌下经过水濂时随水势到水池内，剩余的通过喷雾室重新冲冼由排风机抽走，进而使排到室外的空气air达到和实现最好的诘白作用，满意环境保护请求。

The variant most likely to show pI values different from that of HbA when run on an isoelectric focusing gel.

在跑IEF时最有可能表现出与HbA不同pI的变种。浪花带的成岩作用或渗滤作用是影响同生碇酸盐的起盐囱水变化的另一个因素。

We have presented a practical method for the preparation of propargylic alcohols from terminal alkynes and carbonyl compounds promoted by KOH in the presence of 18-crown-6,and subsequent efficient cyclizations of propargylic alcohols with 2-naphthol catalyzed by InCl_3·4H_2O under the solvent-free ball-milling conditions.Ball milling exhibits its superiority over the reported methods in the preparation of propargylic alcohols and naphthopyran derivatives.

采用机械研磨方法进行了连续的两步固相化学反应的研究：首先，在氢氧化钾和18-冠-6的作用下，端基炔和羰基化合物在机械研磨条件下反应可以高效地生成相应的炔醇化合物；其次，在四水合三氯化铟的催化作用下，生成的炔醇化合物和2-萘酚在机械研磨条件下环加成生成相应的萘并吡喃产物。

The research result about abnormal pressure shows insufficiency of compaction disequilibrium as the sole cause of high pore fluid pressures, and tectonic compression, aquathermal expansion, diagenesis, hydrocarbon generation etc also can be the generating mechanisms.

一般认为欠压实是最主要的异常高压成因机制。由于构造挤压引起压应力的改变，由于水热膨胀、成岩作用、烃类生成等引起体积的膨胀，或由于流体流动和浮力作用也可产生异常超压。
