迁移

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。

Nearly 80% of total Cr drained from outfalls of the factory can be reduced by sulfides and tannic acid originally in the wastes before they ent

实验结果进一步证实了胶州湾娄山河口及沿岸海域中铬的可能的迁移机制为Cr_水~→Cr_水~→Cr_水~→Cr_底质~(酸溶→Cr_~总，并为这一过程作了定量估算，提出了胶州湾娄山河口海域铬的迁移模式图。

The tracer migration test in horizontal assembly is an important part of the field tracer migration test of nuclides in aquifer.

在水平组件中的迁移试验是核素在含水层迁移试验的重要组成部分。

"We found the bird flu virus H5N1 is now also in migrating geese, ducks and other wild fowl and probably moving across the world as flocks migrate beyond the area of the center of current avian flu epidemic," he added.

他进一步的说明：「我们目前也在一些迁移的鹅、鸭和其他野鸟禽类身上发现H5N1禽流感病毒。而这些病毒，也可能由目前的禽流感流行中心区域，伴随著鸟群的迁移，扩散到全世界其他的地方。

Particularly in east Africa, the loss of land to national parks, game reserves, hunting blocks and conservation severely restricts pastoral mobility as much of this land either consists of critical dry- or wet-season grazing or cuts across seasonal migration routes.

特别是在非洲东部，国家公园、猎物繁殖保护区、狩猎区及保护区侵占了大量的土地，从而使游牧迁移受到了严重的限制，因为这些土地不仅包括旱季和雨季主要的放牧区，而且还切断了季节性迁移的必经之路。

The results are in good agreement with the literature′s results which are calculated either from transport number obta...

计算结果与文献中采用经验公式计算迁移数得出的结果和文献中根据电化学电池法测定迁移数得出的结果相符。

The appearance of electronic conductivity makes the ionic transference number is smaller than unity. Therefore the corresponding mole entropy of oxygen ions decreases with the oxygen partial pressure.

由于电子空穴和电子电导的出现，使得氧离子的迁移率小于1，由此计算出的氧离子迁移的部分摩尔墒随氧分压的减小而减小。

The experiment results showed that the addition of ZSM5 could improve the lithium ion transference number and enhance the ionic conductivity of PEO-LiClO4 at the same time.

利用交流阻抗-稳态电流相结合的方法对CPE的锂离子迁移数进行了测定，结果表明掺入ZSM5后锂离子迁移数明显升高。

The analysis of polymer structure indicates that the non-crystalline phase is the majority of the agglomerate structure and the crystalline phase is the minority, the highest crystal value only reaches the level of 0.1646;There is a definite interactionadditives and PVA, which not only reduces the crystal value of ASPE to make amorphous areas enlarge but also improve the ability of segmental motion by destroying the well-regulated and orderly character of polymer chain, meanwhile restricts the mobility of potassium cation and enhances the anionic transference number of hydroxide ions, all these improve the ionic conductivity;The ionic conductivity occurs essentially within the amorphous phase of the ASPE;The structure of ASPE doesnt change in the range of our test temperature, this means, the temperature only takes effect on degradation of complex in certain compositions, ionic mobility and segmental motions of the polymer chain.

聚合物结构分析表明：碱性固体聚合物电解质中凝聚态结构以非晶态为主，仅有少量的晶态，结晶度最大为0.1646；添加的各组分与PVA之间都有一定的相互作用，这种作用不仅破坏了聚合物链段的规整性，能够降低聚合物的结晶度，增大无定形区域，提高链段运动的能力，同时这种作用限制K~+离子的运动，提高OH~-的迁移率，从而提高离子电导率；碱性聚合物电解质的离子传导主要发生在无定形区；在本实验测试离子电导率温度范围内，聚合物内部的结构不会发生变化，即温度只会影响电解质内部络合物解离程度和载流子迁移以及聚合物链段运动的情况。

As pollutant migrated into the capillary zone,capillary tension restricted the vertical movement.The pollutant must overcome the entrapment pressure of oil-water interface before entering the capillary zone, and pollutant accumulated on the top of the capillary zone to become pressurized.The pore pressure of pollutant exceeded the entrapment pressure of oil-water interface,and pollutant entered the capillary zone and formed a lens above the groundwater level.

当污染物迁移到地下毛细管区后，其向下的运动将整体受到毛细张力的阻碍，污染物要想进入毛细饱和带必须克服油-水界面的进气压力，这时污染物在毛细饱和带顶部聚集以期获取压力，同时将产生以水平方向为主的迁移，最终随着污染物的压力超过其进气压力，导致污染物进入毛细饱和带，在地下水水位上形成一个透镜体。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
