迁移

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成"前体腔上皮"，经再分化形成新的体腔上皮。

The comparison of time spent on MSA migration in deeper glacier ice of Antarctic Peninsula and that in the surface infiltration congelation ice of mid latitude glacier suggests that the quick formation of interlinked network of veins in ice, higher temperature and more water content of the ice probably may sever as the promoting factors for the MSA migration.

南极半岛 MSA迁移过程需要很长时间，而表层渗浸-冻结冰层中 MSA迁移过程很快出现，说明冰中脉状纹理的加快形成、较高冰川温度和冰层中的较大含水量等因素会对 MSA"迁移"进程起促进作用。

Results of experiment and theoretical analysis indicate that free water movement in wood under floating pressure consists of two parts, one is mass movement caused b capillary pressure, the other is the movement of water vapor produced by evaporation or ebullition of free water, and the latter dominates the moving process of free water.

试验结果和理论分析显示，在真空－浮压干燥过程中自由水的输运由两部分完成，一部分为毛细管压力下液体的团块迁移；另一部分为在压力梯度下，由于压力波动而引起自由水的蒸发或沸腾后所产生的水蒸气的迁移，且后者在自由水的迁移过程中占主导地位。

Electrokinetic transport process could promote effectively the desorption and migration of phenol and 2,4-dichlorophenol in soil; electromigration and electroosmosis were the main mechanisms; and the .

结果表明，电动力学过程能有效地促进土壤中苯酚及2，4-二氯酚的解吸附和迁移，电渗析和电迁移是其主要的作用机理，其迁移效果与电动力学形式、污染物类型、土壤酸碱性质和电极反应等密切相关，可以采用适当的电动力学工艺修复含酚类化合物的污染土壤。

In order to complete the investigation, impersonality feasible experiment solutions and devices are designed independently to systemically investigate on activation and transfer characteristic of soil heavy metal under acid rain effect. Primary results are shown as followings:1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation.The result has substantial differences with that gotten by most of investigationers in similar work before.

这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。2、酸雨对盐基离子活化迁移产生的影响勿庸置疑，但是，在盐基离子活化迁移的过程中，并没有出现预想中的重金属元素活化迁移现象，表明土壤中的重金属元素并不如理论分析的那样对酸雨沉降反应敏感。

With simplified assumption made for the modal trial mass ratio and the linear response characteristic of the holobalancing technique, the transfer matrix corresponding to a certain correction plane then is extended to the trial set transfer matrix, which is related to a certain order of modal trial mass set. The number of trial runs necessary for the balancing operation is reduced and the balancing efficiency is improved.

借鉴Darlow混合法中模态试重组的思想，通过对模态试重比的简化假设，利用迁移矩阵的线性可叠加性将对应于某单一平衡面的迁移矩阵扩展为对应于某阶模态试重组的迁移矩阵，从而减少了平衡高阶不平衡量所需的试重起车次数，提高了现场平衡效率，且平衡效果良好。

The studies of this field focus on two principal problems: one is why to migrate, and the other is how to migrate.

该领域的相关研究主要围绕两大问题展开：一是为何迁移，二是怎样迁移，前者即迁移的机理与动因，后者即迁移成本、收益、特点及趋势。

The research of training transfer has been the focus of the training domain in recent 20 years. After the previous research summarized, individual characteristic factors and training transfer climate can influence training transfer most. However, many research results are different and there is a lack of pivotally common variables influencing different trainings and transfer situations.

关于培训迁移的研究是最近20年来培训领域的研究热点，总结以往的研究可以发现，培训迁移气氛和个人特征因素这二大类因素对培训迁移的影响最大，但是许多的研究结果并不一致，缺少影响不同培训和迁移情境的关键的共同变量。

Some experiments have been done by simulating in-situ hydrate formation system by gas migrating in seepage system in a glass bubble cell.The phenomena in experiments indicate that gas migration can change the quality of mass and heat transfer of the interface between gas and liguid when hydrate is forming,and it's a moving process of equilibrium curve.There wil...

在鼓泡透明玻璃反应釜里模拟渗漏系统气体穿越多孔隙砂层形成水合物的过程实验，分析了气体迁移对气体水合物形成时气液界面的传质传热性质影响，表明实验中气体迁移形成水合物的过程是一种相平衡曲线动态移动的过程；在形成水合物的气—液界面存在具有一定厚度的过渡层，只要过渡层内气体达到饱和即可形成水合物；气体在迁移中不断形成水合物并在孔隙中形成过压，导致地层骨架的力学破裂和失稳；必须建立一个新的水合物相图以适应气体迁移形成水合物过程的这种新特性。

The conclusions of the study were as follows: 1 Prompts to self-explain promoted procedural learning, procedural near transfer, procedural far transfer. But prompts to self-explain didn"t promoted students" success on the conceptual assessment. 2 Direct instruction on a correct procedure and the cause lead to greater procedural learning, procedural near transfer, procedural far transfer than direct instruction on a correct procedure only. The difference was remarkable. But it didn"t promote students" success on the conceptual assessment. 3 Self-explanation promoted the invention and using of various correct procedures. The subjects, which under direct instruction on a correct procedure and the cause condition, made further use of correct procedures and more averagely. Both self-explanation and instruction of the cause strengthened correct procedures and weakened incorrect procedures.
