METHODS: We systematically searched for placental miRNAs in maternal plasma to identify miRNAs that were at high concentrations in placentas compared with maternal blood cells and then investigated the stability and filterability of this novel class of pregnancy-associated markers in maternal plasma.

我们系统收集了母体血浆中胎盘miRNAs，鉴别出那些胎盘中浓度比母体血细胞中浓度高的miRNA来，然后研究母体血浆中这种新型妊娠相关标志物的稳定性和可滤过性。

The Huabiao brand T-1804 Middle Distillate Flow Improver ( diesel oil pour- point depressant ) was jointly developed by Beijing Organic Chemical Plant and Chin- ese Research Institute Of Petroleum Processing in1976 , it is manufactured by high pressure polymer processing , it is effective to depress cold filterability pour point .

我公司生产的"华表"牌T-1804柴油流动改进剂是北京有机化工厂与中国石油化工科学研究院于1976年开始联合研制开发的，采用高压聚合生产工艺，产品能有效降低柴油的凝固点和冷滤点。

Therefore, in the changing history of Chinese empire, blood ties, private relationship along with face could be deemed as filterable virus which hampers the fairness of official selection in every dynasty, and also trigger the occurrence of corruption unavoidably flourish in official selection.

因此，在中华帝国的历史更迭中，血缘以及由此推展开去的私人关系和"面子"是妨碍我国历代官员选拔公正性的痼疾，它像一种滤过性的病毒，使我国历朝历代的官员选拔无一例外地滋生弊端和腐败。

尽管噬菌体属于病毒，但"噬菌体"这个称呼仍然泛指某些特殊的可滤过的感染性病原体。

In the unsterilized soil, the colonization of JMC1402P was affected by the physical and chemical factors of soil, and the aboriginal microbe would compete with it.The safety of releasing JMC1402P to the surrounding was tested, the design was as follows: mixing JMC1402P and R. huakuii JS5A16L, JMC1402P and Pseudomonas fluorescens Pf.X16L2 in filterable membrane, sterilized soil and unsterilized soil.

JMC1402P标记菌株释放环境的安全性研究表明，当JMC1402P与华癸中生根瘤菌JS5A16L、荧光假单胞菌Pf.X16L_2混合培养在微孔滤膜上、灭菌盆装土及田间三个环境中时，未检测到华癸中生根瘤菌JS5A16L和荧光假单胞菌Pf.X16L_2中有gfp基因编码的绿色荧光蛋白的存在，在X-GlucA作用下亦没有带有gusA基因的发光菌落。
