Construction of the homologous arms directing the homologous recombination For the sake of seeking for the more efficient integrating strategy to make the foreign gene insert in the specific site and don't destroy the host expressional and regulatory elements such as promoters and introns, we experimented targeting the Bombyx morl fibroin heavy-chain exon II with the green fluorescent protein gene by homologous recombination technology.

为了探索一条更为有效的整合策略，使外源基因能定点整合到靶位点，又不破坏宿主基因的启动子、内含子等表达调控元件，令外源基因对宿主生理功能的影响达到最小，我们以丝素重链基因2号外显子为整合靶位点，以便将外源基因定点整合其间。

The results show that with the content of the synthetic compound increasing, the surface resistivity of PVC materials was decreased. When the content of the synthetic compound reached 4.5%, the surface resistivity of PVC materials was reduced below 3.0×108 ?.

结果表明：随合成长链季铵盐的添加量增大，PVC材料的表面电阻率降低，较小的添加量(4.5%)即可使材料的表面电阻率降低至3.0×108 Ω以下，达到了煤矿行业对高分子材料抗静电性能的要求。

Treatment of small bone flap craniotomy and recombinant streptokinase integrated the virtue of minor injured operation and genetic medicine,and is a simple and effective method for hypertensive cerebral hemorrhage.

小骨窗加重组链激酶引流治疗高血压脑出血，结合了微创手术和基因药物的优点，是简便有效的治疗方法。

Treatment of small bone flap craniotomy and recombinant streptokinase integrated the virtue of minor injured operation and genetic medicine,and is a simple and effective method for hypertensive cerebral hemorrhage.

小骨窗加重组链激酶引流治疗高血压脑出血，结合了微创手术和基因药物的优点，是一种简便有效的治疗方法。

The relative small o-Ps lifetime (1.48—1.63ns) can beexplained by the rigidity and high packing density of molecule chain, due to theintrachain and interchain hydrogen bond interaction respectively, whereas in 〓-containing chitosan, the grafted 〓 that play a significant chemical inhibition andquenching role on positronium formation and annihilation is first observed.

CS的相对小的尺寸和较低的自由体积浓度归因于氢键作用而致分子链较为致密的堆砌，在〓-CS中首次发现了〓基团对正电子素湮没的抑制和猝灭作用，此时〓和〓不再直接对应于自由体积尺寸和浓度。

Using the smallest density projection may clearly demonstrate the internal earandmay obtain the auditory bone chain and the internal ear three dimensional three-dimensional image using ssd-3d.

运用最小密度投影可以清楚显示内耳骨迷路及膜迷路，运用ssd-3d可以得到听骨链及内耳骨迷路的三维立体影像。

An improved chemical method for the determination of the molar substitution degree of hydroxyethyl guar gum has been described.

本文用模型小分子一缩二乙二醇的醚键断裂实验证明了可行性，羟乙基瓜尔胶上的羟乙基链段与过量对甲苯磺酸-乙酸酐在130℃下反应14hr，醚键完全断裂生成酯，并在pH=11条件下煮沸1hr使酯完全水解，转变为乙二醇。

This is a minor event chain that describes the religious revival in ante-bellum USA.

这是一个描述美国内战前的宗教复兴的小事件链。

The depressing ability of the macromolecule organic depressants can be improved by the increase of their D.S.. The high D.S. CPVA and CPEG show strong depressing ability to calcite, while CPEG indicates strong depressing ability to diaspore, and HPAM to pyrite.The depressing mechanism of organic depressants was confirmed by the measurements of zeta potential, contact angles, adsorption capacity and IR spectrum.

利用动电位、接触角、吸附量和红外光谱等测试方法和手段，探讨了抑制剂的作用机理：苯氧乙酸类小分子抑制剂与方解石之间可发生较强的化学作用，可以选择性地吸附在方解石表面，使捕收剂发生解吸或阻止捕收剂在矿物表面的吸附而使矿物受到抑制；大分子抑制剂则主要是依靠亲固基吸附在矿物表面，再利用其长链的强亲水性而使矿物受到抑制。

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。
