不迁移的

Firstly, system model depicted by TSIOA is transformed into an USTGSS (untimed stable label transition graph of symbolic state) which does not contain abstract time delay transitions. Then, the testing methods based on LTS are used to the generate transition sequences from USTGSS according to structural coverage criteria. Finally, a process of constructing and executing the test cases is given, in which object functions of time delay variables are imported, and time delay variables used in the transition sequences are solved dynamically by linear programming techniques.

该方法首先将时间安全输入/输出自动机描述的系统模型转换为不含抽象时间延迟迁移的稳定符号状态迁移图(untimed stable transition graph of symbolic state，简称USTGSS)；然后采用基于标号迁移系统(labeled transition system，简称LTS)的测试方法来静态生成满足各种结构覆盖标准的包含时间延迟变量迁移动作序列；最后，给出了一个根据迁移动作序列构造和执行测试用例的过程，该过程引入了时间延迟变量目标函数，并采用线性约束求解方法动态求解迁移动作序列中的时间延迟变量。

Measurements and Main Results: ATRA stimulated NB4 cells to transmigrate toward the A549 cells in a time- and dose-dependent manner. Replacement of A459 condition medium by its original medium abrogated this transmigration.

测量与结果：全反式维甲酸会刺激 NB4 细胞迁移至 A549 细胞，并且具有时间与剂量之效应，若是以单纯的培养液取代 A549 细胞之条件培养液，则 NB4 不会有迁移的作用。

The results showed that HGF not influenced the proliferation and osteogenic differentiation of bone marrow-derived mesenchymal stem cells.

结果表明，重组人HGF不影响骨髓间充质干细胞的增殖和向成骨细胞的分化，但可明显促进骨髓间充质干细胞的迁移并抑制anoikis诱导的细胞凋亡；PI-3K和MAPK途径参与了HGF促进细胞迁移的作用。

Furthermore,the adsorption of acetylene on the Ni(111)surface is investigatedby DV-Xα method,as well as its migration pathway from the aligned bridgesite,the favorite adsorption site for ethylene,to the cross-bridge site.Afterstudying several reaction pathways of C2H2 on Ni(111),we find that acetylene,as the product of dehydrogenated ethylene,will migrate from the alignedbridge site to the cross-bridge site with a very small energy barrier,0.02eV.

给出了乙炔在各个吸附位的吸附结构，并在假定乙烯在脱氢前没有迁移的基础上，对各种可能的反应途径作了模拟研究，发现乙炔在平行桥位的吸附结构不稳定，通过1.24的平移和30度的旋转的耦合，迁移到垂直桥位，迁移过程中只有0.02eV的势垒。

So the same-intensity hurricane today wreaks all sorts of havoc that wouldn't have occurred had human beings not migrated.

因此，如今，同样强度的飓风能造成重大破坏，如果人口不迁移，破环就不会这么大。

Just why they took so long to travel north is not clear, but many researchers have suggested that the bone-dry Sahara Desert was a major barrier to migrations from the south.

至于人类究竟为什么在这么长时间之后才开始朝北迁移，原因尚不清楚。然而，许多研究人员提出，极为干燥的撒哈拉沙漠是自南向北迁移的主要障碍。

In OWE-SOJ test, a fluffy colony without clampconnection formed in the A=B≠mating interaction where nuclear migration occurs, whilea barrage colony without clamp connection formed in A≠B= interaction where nuclearmigration do not occur. The two colonies could be distinguished clearly from each other.

而在OWE-SOJ试验中，发生核迁移的A=B≠交配反应形成无锁状联合的绒毛状菌落，而不发生核迁移的A≠B=反应形成无锁状联合的栅栏型菌落，两种菌落可以清楚地区别开来。

Different non-directional cell migration,but migration of cells in the same direction is constant.

不同的细胞有不定向的迁移，但同一个细胞的迁移的方向是恒定的。

International Phonetic Alphabet to master pronunciation of English not good, hard American accent or English accent. 3 unfamiliar grammar structures, do not know how the combination of the laws of English sentences. 4 a lack of listening skills and do not know how to listen to only the most effective. 5 the lack of positive and effective English thinking, do not understand the use of Chinese thinking on the English-speaking听说读写译especially great to hear a negative transfer effect. 6 psychological barriers exist, do not know the owner of that happy state of good full confidence and strong desire to make listening better listening comprehension.

对英语国际音标发音掌握不好，分不清美国口音还是英国口音。3语法结构不熟，不懂得英语句子的组合规律。4听力技巧缺乏，不懂的如何听才最有效。5缺乏积极有效的英语思维，不懂的运用汉语思维会对英语的听说读写译特别是听的产生很大的负迁移的效应。6存在心理障碍，不懂的拥有愉快的心情，良好的状态充分的自信和强烈的听音欲望会使听力理解的效果更好。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
