In OWE-SOJ test, a fluffy colony without clamp connection formed in the A=B≠ mating interaction where nuclear migration occurs, while a barrage colony without clamp connection formed in A≠B= interaction where nuclear migration do not occur. The two colonies could be distinguished clearly each other.

Prestack time migration is a key technology that can image steep dip angle formation and complex fault system. It yields accurate velocity field and definite fault compared to poststack time migration.

叠前时间偏移技术是一项解决地层倾角大、断层复杂成像的关键技术，可以求取准确的速度场，偏移后断层清晰。

Different non-directional cell migration,but migration of cells in the same direction is constant.

不同的细胞有不定向的迁移，但同一个细胞的迁移的方向是恒定的。

For the oxidation channel from OH group migration to O atom insertion,the activation energy barriers for OH migration are 58.4,65.3, and 79.2 kcal/mol,respectively,whereas those for O atom insertions beginning with directly destroying Si_a-Si_s backbonds by a foreign H_2O molecule are much lower,the respective values are 19.0,16.7,and 24.8 kcal/mol.

对于先经过OH迁移致使O原子插入Si_a-Si_s backbond的氧化途径，OH迁移所克服的能垒依次为58.4、65.3和79.2 kcal/mol，而H_2O以O原子进攻Si_a位来打开Si_a-Si_s键进而使O原子插入的能垒则相对较低，仅为19.0、16.7和24.8 kcal/mol。

By comparing and analyzing the migration results of single directional beamtet and beamlets with different windows and directions, we demonstrate the validity of the prestack depth migration with Gaussian beamlets method.

通过对单个，以及多个小波束源偏移结果对比分析，验证了Gaussian小波束叠前深度偏移方法的有效性。

According to migration and accumulation model, fined that the fan body controls the pool scale and the unconformity or the fault plays the hydrocarbon migration path role and shading function, therefore, fan body directly contacted with the source rock is the exploration goal to find the pool of generation and accumulation hydrocarbon by itself, or the fan body communicated source rock with unconformity or fault is the structure-lithological pool.

根据成藏模式，发现扇体控制着油藏的规模，不整合或断层起着油气运移通道作用和遮挡作用，因此与烃源岩直接接触的扇体是寻找自生自储岩性油气藏的勘探目标，通过断层或不整合与烃源岩沟通的扇体是寻找构造—岩性油气藏的目标。

In this paper, preliminary FDS fire chamber to simulate the flue gas generated through the corridor adjacent to the room near the migration laws, an analysis of indoor air flow field and the movement of smoke layer, and through the simulation of fire scenes, in a simple form of visual dynamic display of the entire process of fire, in the simulation process to obtain more accurate fire-related parameters such as temperature distribution, gas flow and heat radiation, and analysis of simulation results through the fire chamber of the flue gas migration characteristics, results showed that the chamber in the absence of fire smoke control measures, the process of the spread of smoke filled the first chamber is at the top, with the passage of time, the proliferation of slowly downward until the entire chamber is full, and then through the corridor smoke quickly spread to the nearby chamber.

本文运用FDS初步模拟了腔室火灾产生的烟气通过毗邻的走廊向附近房间迁移的规律，分析了室内空气流场和烟气层运动状况，并通过对火灾场景的模拟，以简单直观的形式动态显示出火灾发生的全过程，在模拟过程中获得较准确的火灾相关参数，如温度场分布，烟气流动及热辐射等，并通过模拟结果分析腔室火灾的烟气迁移特性，结果表明着火腔室在无防排烟措施的情况下，烟气扩散的过程是首先充满腔室顶部，随着时间的推移，慢慢向下扩散，直至将整个腔室充满，然后烟气通过走廊快速向附近腔室蔓延。

In the present study, patch-clamp whole-cell recording, transwell migration assays and organotypic cerebellar slice cultures were used to examine the effect of melatonin on granule cell migration.

在这篇研究中，我们使用膜片钳、Transwell迁移分析法和小脑脑片培养方法，观察MT对颗粒细胞迁移的影响。

When cutting tool roaled of spindle's hole by manipulator or other ways,the pull nail behind of knife hilts is sent to ahead of tension bar of spindle. When receives the clamps signal, the pressure oil is passed over the oil cylinder left cavity of the spindle rear part, the piston to the right migration ,tension bar also to right migration by small dish shape spring function, the stell ball of ahead circumference of the tension bar shrink the distribution diameter by spindle's cone hole's force, holds on the knife hilts and pull nail colsely.

当刀具由机械手或用其他方法装到主轴孔后，其刀柄后部的拉钉便被送到主轴内拉杆的前端，当接到夹紧信号时，将压力油通入主轴尾部的油缸左腔，活塞向右移动，拉杆在碟形弹簧的作用下也向右移动，其前端圆周上的钢球在主轴锥孔的逼迫下收缩分布直径，将刀柄拉钉紧紧拉住。
