预作用

Gz exposure might produce ischema-reperfusion effect on rat brain and the function of repeated +Gz exposure was similar to that of ischemia prestimulation.

Gz暴露可对大鼠脑产生类似缺血再灌注的作用（Glaister，1988），反复+Gz暴露可对大鼠脑产生类似缺血预刺激的作用。

DS is a safe and effective pretreatment, which can mobilize HSC, but also vocate niches for transplanted HSC homing.

DS是一种安全、有效的预处理方案；DS对造血干细胞既有动员作用又有促进龛位腾出以供移植干细胞回巢的作用。

Meanwhile, we discuss the deinking mechanism:solvent treatment dislodges most ink particles, then enzyme removes part of unconnected ink particles from the fibers so as to improve deinking effect of mixed office waste paper.

同时 我们对其脱墨机理进行初步研究，可以认为其作用机理为：先用溶剂预处理，将大部分油墨粒子从纤维上分离下来，然后再辅以酶的作用，将部分未与纤维分离的油墨粒子从纤维上剥离下来，从而大大地提高了混合办公废纸的脱墨效果。

The experimental results suggested that this process of pretreatment can get good results, The act of breaking lignin is so distinctness that it is more propitious to the e...

试验结果表明，通过超剪切粉碎机粉碎后，物料的粉碎细度良好，同时对木质素的包裹也有明显的破坏作用，更加有利于酶的作用，并减少了预处理阶段的成本。

Our results indicated that (1) aortic rings with and without endothelium precontracted by NE to decreased pH induced a relaxation; aortic rings with and without endothelium to increased pH induced a contraction; there is no significant difference in presence and absence of endothelium .(2)NO levels had no significant change in isolated aortic rings presence and absence of endothelium to decreased pH and increased pH ;(3)sulfite levels in isolated aortic rings with endothelium reduced to decreased pH and increased pH. sulfite levels in aortic rings without endothelium had no remarkable change.

结果：①NE预收缩后，pH值降低对内皮完整和去除内皮胸主动脉血管环呈舒张作用；pH值升高对内皮完整和去除内皮胸主动脉血管环呈收缩作用；内皮完整组与去内皮组相比无显著性差异；②pH降低和升高对内皮完整和去除内皮血管环中NO含量无显著性影响；③pH降低和升高均可使内皮完整血管组织中亚硫酸盐含量减少，对去内皮血管中亚硫酸盐无显著性影响。

Objective: We have studied Baizhus effects of suppressing tumors and anti-metastasizing during our pretests. In order to discuss the mechanism further, we have respectively studied its effects from three aspects.

目的：预试验对于白术抑瘤及抗肿瘤侵袭和转移的作用进行了研究，确定白术具有抑瘤及抗肿瘤转移的作用，为进一步探讨其机理所在，本研究从三方面作了更细致的研究。

It is found that great difference between testing results was generated by little difference of air-void in rutting specimens.

该模型可预估不同空隙率混合料在不同轮载作用次数下的车辙深度，也可对不同空隙率试件在不同轮载作用次数下的车辙深度进行转化。

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。
