So, the blowhole defective belongs to a technology difficult in the session of casting, and has a lot of values for research.

本论文以在KW造型线上生产的4100QB机体作为研究对象，详细介绍了4100QB机体产生的侵入性气孔的形成机理。

According to the research of the paper, the "migmatite" of the Sizishan Formation, Xingdong Group distributed in northern Xiao Hinggan Mountains should be a suit of gneissic quartz monzonitegranite intrusions. Their whole rockmineral Rb-Sr isochronic dating is (482±19) Ma, indicating that an Caledonian magmatic events existed in the giant granitic belt of the Xiao Hinggan Mountains.

研究表明，分布于小兴安岭北部金林林场的兴东群四子山组"混合岩"为一套片麻状石英二长岩-花岗岩侵入体，岩石全岩-矿物Rb-Sr等时线年龄为(482±19) Ma，这表明小兴安岭巨型花岗岩带中存在早古生代岩浆事件。

The supersession of the new and old root was related with the peak of the second stage juvenile (J2). The temporal and spatial dynamics of invasion for the SCN had closely related with the soybean root development.

首次提出大豆胞囊线虫二龄幼虫高峰的出现与大豆根系新老更替密切相关的观点，并研究了线虫的侵入和分布与根系发育的时空动态。

The yield of mulberry leaves were influenced by the total branch length per tree and the number of Meloidogyne arenaria in root system.

研究表明，分布于小兴安岭北部金林林场的兴东群四子山组&混合岩&为一套片麻状石英二长岩-花岗岩侵入体，岩石全岩-矿物Rb-Sr等时线年龄为(482±19) Ma，这表明小兴安岭巨型花岗岩带中存在早古生代岩浆事件。

Results show that the heavy rainfall event occurred under the favorable environmental conditions, resulted from the interaction of mid-and low-latitude systems. The mesoscale convergence and the mesoscale low triggered the occurrence of the heavy rainfall. Rain clusters bringing the heavy rainfall were related to meso-β systems. The meso-β mesoscale rain clusters appeared to the north of the cyclone center on 1000 hPa after filtering and to the south of the meso-α convergence line on 850 hPa.

分析表明：暴雨发生在高低空流场及中低纬系统配置非常有利的天气背景下，是多种尺度天气系统相互作用的结果；在对流性不稳定层结中，冷空气沿等熵面侵入到中尺度辐合系统中，激发了中尺度低涡的迅速发展，在孟加拉湾和南海源源不断输送的水汽配合下，导致了暴雨的发生；中β尺度对流雨团发生在滤波后1000 hPa 等压面的低涡中心北侧和850 hPa 中α尺度辐合线南侧，呈现暖式切变的降雨特征。

This paper researches on 4100QB Cylinder-block of the KW moulding line , particularly introduces the forming mechanism of blowholes on 4100QB Cylinder-block.

They often had more matrix regions more than one which were different in electron dense, infection thread wall thickness and bacterial number.

根瘤的形成十分复杂，首先是根毛受细菌的影响·发生卷曲，形成形状不同的侵入线[5]，随后侵入线进入植物根部，激活。。。。。。

Formation of infection thread and nodules at early symbiotic stage between 2-33 and A. sinicus were monitored in situ by using laser confocal scanning microscope and fluorescent microscope.

利用激光共焦扫描显微镜和荧光显微镜原位监测了标记菌株2-33与紫云英早期共生结瘤阶段的侵入线与根瘤形成过程。

Infection of legume roots begins with attachment of rhizobia to the root surface Biochemical signals are exchanged between the partners and then rhizobia invade the root hairs through an infection thread.

根瘤菌先接触被侵染的作物根的表面，互相交换生化信号后，根瘤菌通过侵入线侵入根毛。
