同时，由于鲜水断裂带不同断裂间的相互作用，发生地震的断裂在其相邻的断裂上产生同震库仑应力增加，使下次地震发生于其相邻的断裂上，这也可能是鲜水河断裂带地震沿带南北迁移的重要物理机制。

Most patients' death arise from the metastatic spread of primary tumors There is an urgent need for the finding of novel anti-tumor and anti–metastatic drugs to improve the quality of life and survival rate of patents Justicia procumbens is an herb and used to reduce fever inflammation and canker in Taiwan We've detected that 0 3 μM JA could effectively inhibit the proliferation of oral cancer cells OC-2 and HSC3 but not normal oral keratinocytes in MTS assay JA-treated OC2 underwent apoptosis as suggested by increased sub-G1 DNA contents condensed nuclear morphologh and DNA fragmentiation The migration activity of OC-2 was also significantly reduced by treatment with low concentration of JA The expression of ?

大部分的口腔癌病患死於原位癌的转移和扩散，寻找有效抗癌和抗转移的药物疗法来增进病患的生活品质和存活率，对治疗口腔癌而言非常重要。爵床草是台湾民间常用草药，常被用来消炎止热和治疗口疮、乳瘤。我们利用MTS分析，发现处以0 3 μM的JA 48小时，即可有效抑制口腔癌细胞OC-2和HSC3的增生，但不影响正常口腔上皮细胞生长。OC-2经JA处理后，其sub-G1的DNA含量增加，并可观察到DNA固缩和梯度断裂的现象，说明JA可使OC-2走向细胞凋亡。除此之外，0 3 μM的JA亦可有效降低OC-2的迁移能力。

The biometallogenesis system of Jinya gold deposits consists of the following procedure: pre-concentration of gold and metallogenic matter in living organisms in Luodian-Danchi rift depositional basin; solution, absorption and concentration of metallogenic matter in organic matter and organic thermal fluid generated from organisms during lithogenesis; migration of gold and metallogenic matter in organic fluid from basin to Lingyun underwater carbonate platform and concentration at its boundary convex (palaeo-blind-mountain) during basin compaction ; metallization due to depth thermal fluid making organic fluid thermal degradation and forming new fluid which riches in gold and sulfur, and the fluid migrating upward and depositing in upside ore-controlling structures because of absorptions by organic carbon and atc.

通过研究金牙金矿作用的生物成矿系统内容为：在早、中三叠世罗甸—丹池裂谷盆地接受沉积时，生物对金等成矿物质就存在预富集作用；在成岩过程中，生物转化为有机质及有机热流体，对生物及沉积物中的金等成矿物质存在溶解、萃取、富集作用；在盆地压实成岩作用中，盆地中有机热流体向凌云水下碳酸盐台地运移，并在台地边缘外凸部位集中，此过程流体携带大量成矿物质，对金等成矿物质存在迁移集中作用；深部热流上侵使有机流体发生降解和释放金的热作用、形成高含金的有机热液，含金热液上移在构造通道中沉积并被有机碳再次吸附，最终形成金矿床，对金存在成矿作用。

Especially, sulfide has significant positive correction and negativecorrection with unsteady fractions (acid soluble fraction and reducible fraction)andsteady fractions (oxidable fraction and residual fraction)of Cu and Zn in MSW,respectively. Simulation computation results from Visual MINTEQ showed that Cu~(2+)was mainly associated with humus and migrated from lose association (FA_1-Cu) totight association (FA_2-Cu), while Zn~(2+) was mainly presented with complexation withS~(2-) which was strengthened as the reducing environmental surrounding in landfillgradually.

Visual MINTEQ模拟计算结果表明，渗滤液中Cu大部分为腐殖质络合态，并逐渐由与松结合态富里酸络合态(FA_1-Cu)向稳结合态富里酸络合态(FA_2-Cu)转变；Zn则主要表现为与S~(2-)的络合，其络合程度随模拟填埋场内还原性环境形成而加剧，生物反应器填埋场的渗滤液长期回灌能促使Cu和Zn逐步形成络合沉淀而使其在填埋垃圾内的迁移行为减缓。

Human movement,especially the destruction of vegetation,influenced the propagation environment of the intermediate host of paragonimus,which resulted in the transference of territory of wild animal and the marked decrease of the density and the infection rate of the intermediate host.

人类活动使并殖吸虫中间宿主滋生的微生态环境发生改变，特别是植被破坏，造成野生动物活动范围的迁移，是导致中间宿主密度和感染率下降的主要原因。

Signalling through CXCR4 mediates actin polymerization and pseudopodia formation in cells, and induces chemotactic and migration to target organs. In addition, CXCR4-SDF-1 axis can promote tumor angiogenesis and growth.

CXCR4在肿瘤组织中的表达明显高于正常组织，而肿瘤常见转移部位均为CXCR4的配体基质细胞衍生因子-1(stromal cell derived factor-1，SDF-1)表达丰富的器官，SDF-1与CXCR4结合后可使细胞肌动蛋白丝聚合，形成伪足，从而定向诱导肿瘤细胞迁移到特定的靶器官；此外，CXCR4与其配体SDF-1相互作用可以促进局部新生血管作用，利于肿瘤生长。

For obtaining maximal yield of hydrogen how to make glycolysis to produce large amount of NADH at TCA cycle and also to reoxidize FADH2 through electron transport chain by oxygen or other electron acceptors were chief introduced .

文中着重介绍了如何通过 TCA cycle使葡萄糖酵解产生大量的 NADH(还原型二磷酸吡啶核苷酸)，抑制 NADH脱氢酶络合物的电子迁移链而得到最高氢气产量。

In this particular case, absconding is not caused primarily by colony mismanagement: it is a form of the bees' genetic behaviour which enables them to evade attacking enemies and to migrate to other foraging areas during dearth periods.

在这种特定情况下，潜逃不是管理不善造成的，主要由殖民地：它是蜜蜂的遗传行为的形式，使他们逃避打击敌人，并在迁移期间缺乏其他觅食区。

The method has such advantages as easy operation, stable process and no pollution. The product, when used for fatting leather, can improve the quality, softness and toughness of leather, and can tightly bond with leather fibers. The bonded fatting agent does not transfer in leather, and has such advantages as rapid permeation and uniform distribution, thus can make leather soft and moist.

本发明操作简便，工艺稳定，无环境污染；用本发明制备的产品对皮革进行加脂，不仅能增加成革的丰满性、柔软性、柔韧性，而且能与皮革纤维结合牢固，结合的加脂剂在皮革中不易发生迁移，还具有渗透快，分布均匀等特性，可使皮革柔软、滋润、经久而不枯板。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
