Supercritical conditions can enhance the conversion of isooctane but lower the alkene selectivity simultaneously.

During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.

一般含有0.2%~2.0%的丁二烯，其在烷基化反应中，可生成一种分子量很高的粘稠重质迭合物，使烷基化油的干点升高，辛烷值降低，并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯，同时，将部分1-丁烯异构化为2-丁烯，以提高烷基化油的辛烷值。

We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。

This paper will analysis and research the webpage with its layout and methods, the visual elements and design principles, web standards, the traditional form layout and DIV+CSS layout and so on, in order to find out those criteria which are followed by a good web page on the aspects of design of layout and visual elements. This paper can give people some references when they are doing some design in the future, at the same time, explores new technology of the web page layout, to make the web page layout simple, convenient, easy to operate, increase the readability and alterability of the code, to reduce the redundancy of code program, to increase efficiency of the persons who are producing the web.

本论文将就网页的布局及方法、网页视觉构成要素及设计原则、Web标准、传统的表格布局及DIV+CSS布局等方面进行分析与研究，从而寻找网页布局、视觉构成要素设计等方面所遵循的一些准则，给今后人们在进行网页设计时以一定参考的同时，探究网页布局的新技术，使网页的布局简单、方便、易于操作、增加代码的可读性和可改性，降低程序代码的冗余性，提高网页制作人员的工作效率。

Since microspore mother cells showabortion during the first meiotic divison,it is suggested thatthe early male abortion is frequently associated with variousdegrees of impairment to the fertility to the female〓amate.

研究的27个杂种第一代中，有11个组合的产量超过对照或与对照持平，占总组合数的40.74%。在强优势组合中，不育细胞质带来的负效应不足以使F1产量的显著降低，而且通过杂优补偿作用可比对照有所提高。
