Accordingly with the ZSM-5 zeolite the turning point happened at the conversion of about 55%,the respective contributions were about 20% and 80%, and dealkylation of about 10% of alkylbenzene present in the feed was helpful to form benzene.

在ZSM-5分子筛催化剂上，从芳烃迁移反应向芳烃生成反应的过渡大约发生在转化率55%附近，芳烃迁移和芳烃生成反应对苯生成的贡献分别约为20%和80%，原料中约10%的烷基苯会发生脱烷基反应生成苯。

With the Y zeolite the turning point from aromatics shift to aromatics generation happened at the conversion of about 30%.The respective contributions to benzene formation from aromatics shift and aromatics generation were about 36% and 64%, and the dealkylation of about 5% of alkylbenzene present in the feed was also helpful to form benzene.

We are interested in the molecular mechanisms underlying neuronal migration and our work published in 1999 indicates that there are diffusible molecules in the brain which can guide the direction of migrating neurons; specifically, a secreted protein called Slit is repulsive to neurons and its concentration gradient guides neuronal migration.

我们在分子水平对这个问题进行了研究。1999年发表的结果给出这样一个答案：脑内存在导向性分子，可以指导神经细胞的迁移方向；具体的发现是，一个叫Slit的分泌性蛋白质，对神经细胞有排斥性作用，它的浓度梯度指导神经细胞迁移的方向。

This research is with Jiangxi province exemple, in G IS support falls, build environment of weak modes of life and relation to their environment to evaluate quota system through compose, computational zoology environment is spent flimsily, use the core that migratory model calculates centre of gravity to spend grade flimsily migratory direction and distance.

本探究以江西省为例，在G IS支持下，通过构建脆弱生态环境评价指标体系，计算生态环境脆弱度，利用重心迁移模型计算脆弱度等级的重心迁移方向和距离。

Researches to the gold-bearing quality of sedimentary and magmatic rocks show that most of these rocks have more gold content than the average of the upper crust. Further evidences are quoted to support the view that fluids exist in shallow crust have the ability resolve some gold. Moreover, in the convergent compression, deep melting of the lower lithosphere can bring some Au and mineralization materials and move up to upper crust. Regional faults, which formed in geosynclinal and diwa periods, controlled the partial distribution of intrusions and gold mineralization belts, i.e.

区域地层和岩浆岩的含金性表明，岩浆岩和大部分地层均具较高的金异常含量，而进一步的研究表明浅部地壳的流体对地层中的金具一定的溶解和搬运迁移能力；而在汇聚挤压构造体制下由深熔作用生成的岩浆可以从岩石圈深部携带部分金和其它成矿物质并迁移到地表浅部，地槽期和地洼期形成的区域断裂构造共同控制了中新世岩浆的侵入和金成矿带的分布。

The result shows that the migration ability and distance of U are very limited in the geological, hydrogeological environmental conditions.

初步认为，在当地的地质、水文地质等环境条件下，铀的迁移能力有限，迁移距离较小。

If an upper incisor migrates labially the lower lip may come to lie lingual to the incisal edge of the tooth and produce further migration.

如果前牙迁移labially下唇可能会说谎舌的牙齿切缘和生产进一步迁移。

The causes of them include non-linguistic interference, negative intralingual and interlingual transfer.

导致失误的原因有：非语言因素干扰、语内负迁移及语际负迁移。

These errors could be attributed to negative transfer of Chinese, intralingual transfer and incomplete knowledge of rules concerning subordinate clauses.

从语料分析的角度探讨了语言石化的形成原因，认为语内迁移、语际迁移和文化移入都可以导致语言石化的形成，并分析了这些因素在词汇、语法、句子结构和语篇组织等层面上对中国学生英语写作产生的影响。

By the infiltration test of soil column, the author concludes that Cr and As has the following migration patterns by dynamic researches. 1 The absorption and migration of Cr and As in loessial soil relate to content of mucilaginous grain.

4通过土柱淋滤试验，从动态角度研究得出铬、砷在黄土中具有以下迁移规律及特点：①Cr、As在黄土中的吸附和迁移与土壤中的粘粒含量有关。
