查询词典 migration

One year later, Slit was confirmed as the ligand of Robo and the Slit-Robo signaling is know involved in the repulsive effect of the commission axons crossing the mid-line, and also involved in the repulsive effect of the guidance of neuronal migration and leukocyte migration as well.

而对 Slit 功能展开的研究起于1998年，先是发现其受体 Robo突变型果蝇的中线处交叉神经元的导向发生缺陷。1999年的一系列遗传和生化的研究又发现，分泌性因子 Slit 正是 Robo 的配体， Slit － Robo 信号起到了排斥一些轴突，使之无法穿过中线的作用。

值得注意的是：CFP道集和CRS道集偏移速度建模为我们提供了两种新的偏移速度分析方法。

In this paper, we present a new migration velocity analysis method-synthetic source record interactive residual migration velocity analysis method based on controlled illumination.

提出了一种新的偏移速度分析方法－基于控制照明的合成震源记录交互剩余偏移速度分析方法。

So we can use any 2D prestack procedure to process them, such as time migration, depth migration and velocity analysis.

它通过投影变换的方法，将三维叠前数据体投影为一系列的径向二维叠前数据体，从而将三维叠前问题转化为一系列的二维叠前问题来进行求解，使得三维叠前资料的偏移成像可以在中小型计算机上进行。

The muffle kiln was used in the small scale experiment of sintering, and the atomic-absorption spectrophotometer was used to determine the contents of heavy metals in the samples. This study investigated the migration characteristics of 6 heavy metals in the sintering process of MSWI fly ash, and analyzed the influence of temperature, residence time, modeling pressure, additive and etc. onto the migration characteristics of heavy metals.

首先，采用高温箱式电炉对垃圾焚烧飞灰进行了小型烧结实验，使用原子吸收光谱仪对烧结前后样品中重金属含量进行测试，考察飞灰烧结过程中6种重金属(Cd、Pb、Cu、Ni、Cr和Zn)的迁移情况，并分析烧结温度、时间、成型压力、添加剂等因素对各种重金属迁移特性的影响。

In about a century' s time, their livelihood of swidden agriculture has been changing greatly along with the natural and social environment change. Before 1950s, as a minor group frequently move in the subtropical mountainous area characterized by scarce arable land, high forest coverage rate and sparse population, Kemu people has long been engaged in swidden agriculture which was simple, called for no sophisticated production tools and was suitable for frequent movement. At that time, they adapted to the environment change mainly by moving frequently from one place to another, and their livelihood was featured by complete dependence on environment, frequent movement and swiddening without continuous cultivation. From 1950s to early 1970s, their way of adaptation changed into migration within defined territory and shortterm fallow featured by complete dependence on environment, migration within limited area and short fallow. In early 1970s, they leaned from outside to cultivate irrigated fields and plant cash forest and their livelihood was featured by complete dependence on environment and agro-forestry.

近一个世纪以来，随着其所处自然环境和社会环境的变迁，其刀耕火种的生计方式在不断地变化：20世纪50年代以前，作为频繁迁徙于山多地少、森林覆盖率高、人烟稀少的热带、亚热带山区的弱小族群，以开发容易，便于流动作业不需要复杂生产设施的刀耕火种为其传统的生计方式，主要以迁徙的方式对环境变迁进行调适，其刀耕火种生计方式的特征表现为完全依赖型、随意迁徙型、无轮作型；20世纪50年代至70年代，其主要以固定区域内迁徙和短期轮作的方式对环境变迁进行调适，其刀耕火种生计方式的特征表现为完全依赖型、在固定区域迁徙型、短期轮作型刀耕火种；20世纪70年代初，其主要以外文化——开拓水田及人工造林的方式对环境变迁进行调适，其刀耕火种生计方式的特征表现为部分依赖型、粮林轮作型刀耕火种；20世纪80年代以后，其主要以发展橡胶种植业对环境变迁进行调适，其刀耕火种生计方式的特征表现为暂时依赖型刀耕火种。

Can reverse JA-induced migration inhibition JA-treated cells also showed significantly higher adhesion to laminin In conclusion these results indicate a novel anti-tumor role of JA via reducing reorganization of cytoskeleton increasing integrin 3 expression and adhesion ability to inhibit tumor cells migration Furthermore immunofluorescence staining of phalloidin/actin indicated that JA-treated cells exhibited cytoskeleton rearrangement and significant decreases in the number and length of filopodia Activity of Rho-family small GTPases was detected by a GST-pull down assay and showed that GTP-loaded Cdc42 and Rac were decreased in JA-treated cells In the future we hope these findings will be helpful to further understand the mechanisms underlying tumor progression in oral cancer and subsequently improve the cancer prevention and treatment

以抗体阻断integrin ？3可以有效使OC2恢复被JA所抑制的迁移能力。细胞贴附实验指出JA能提高OC-2在laminin环境下的贴附能力。当我们进一步以免疫萤光染色观察细胞，发现在JA处理下的OC-2，其外形、细胞骨架和细胞边缘的filopodia的密度和长度明显减少，利用GST-pull down assay侦测到Cdc42-GTP和Rac-GTP的表现量降低。推论爵床素A可能透过刺激口腔癌细胞大量表现integrin ？3，使细胞贴附能力增加或是透过改变细胞骨架来降低细胞迁移能力。希望本研究对於JA所做的抗癌及抗转移效应评估能提供口腔癌治疗在研发上一些帮助。

That's what makes this mod unique.

这也正是这个MOD独特。

I now feel furious and want to do something.

现在我觉得非常气愤，想做点什么。
