接合

The engagement of engine and transmission means the linkup between engine and drivetrain to transfer the engine power to the driving axles and wheels .

发动机和变速器的连接就是发动机和传动系统的接合，并以此把发动机动力输送至驱动轴和车轮。

Taking advantage of a rDNA mutant,rdna-A3,which is of paromomycin resistance marker and has replication predominance over wild type r dna+,we demonstrated that among 10 000 copies of rDNA in the old macronucleus no ne could "leak" into the developing new macromucleus during conjugation.

本文以1种具有强大复制优势而且是抗药性的rDNA分子，rdna-A3，为指标，证明在接合过程中旧大核内上万个rDNA分子没有1个能进入新大核，从而在基因分子水平上证明旧大核的退化是极为彻底的。

Fruit globose to ellipsoid, rounded at both ends, slightly compressed laterally, mericarp nearly rounded in cross section, commissural face constricted, glabrous; ribs 5, prominent, acute; vittae 1 in each furrow, 2 on commissure.

果球状到椭圆形，在两末端圆形，侧面稍压扁，分果爿近圆形在横断面上，接合面缢缩，无毛；棱5，突出，锐尖；油管每棱槽1，在合生面上2。

Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent. Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways. First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of"higher"primary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法：本文将镁与无水甲醇直接反应制得甲醇镁；"更高级"的醇（比如C≥ 2的醇）在无催化剂的条件下无法直接和镁进行反应，本文以CCl4为催化剂将无水乙醇与镁直接反应制得乙醇镁，但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应；不论是以CCl4为催化剂还是以原甲酸三乙酯为催化剂，丙醇均无法与镁直接反应。

In this research we discovers that mortise and tenon joint, dovetail joint, tongue joint, finger joint, and dowelled joint are very interesting and functional joint methods.

本研究发现传统的木式结构的对接、搭接、榫接和拼接等的技法是非常有趣和极具功能性的接合方式。

A click member is held vertically movably in the stepped hole of the case band and is urged toward the engaging portion of the bezel composed of a plurality of serrations.

棘爪构件可垂直移动地保持在表环的台阶孔内并推向由多个锯齿部组成的表框接合部位。

This vinyl acrylic copolymer was designed to bond synthetic films, such as polyvinyl chloride, Mylar and cellophane.

这种乙烯基的丙烯酸共聚物是专为粘接合成胶膜而设计的，例如聚氯乙烯、聚酯薄膜和玻璃纸等。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
