The WHO neurosis screening schedule is the best in both sensitivity and specificity of validity, but its practice is time-consuming and laborious, which limits its application. SCL-90 and CMI are imperfect in sensitivity of validity, and they cannot screen out the mental disorder in more than a half of the subjects. In a group test, they can hardly serve as a screening tool. UPI can screen out most of the mental disorder, and its sensitivity of validity reaches 83.1%. Additionally, the UPI questionnaire contains fake-test items, which could retest those who were missed due to untruly or not conscientiously answer the questionnaires. An acceptable way to obtain a true screening test is to give the individuals a propaganda of mental health and explain the questionnaires for 30 minutes before the test, which helps the examinee to understand the procedure and accept the questionnaires, so that the results of the test could be more reliable. In conclusion, UPI is a valuable screening tool to be recommended.

WHO神经症筛选表的灵敏度特异度都是最好的，但其操作费时费力，故适用性受限；以SCL-90和CMI二者的灵敏度很不理想，约一半以上的患者被筛漏，难以用团体测验方式作为筛选工具；UPI的灵敏度达83.1%，绝大多数病患可被发现，量表有测伪项目，可将不真实、不认真填写而遗漏的病患进行重测补救，且测前有30min时间进行心理卫生宣传和介绍防治人员服务内容、联系方法，使存在问题的人主动应询，从而可避免遗漏，是值得推荐的筛选工具。

In this paper we study the biodegradation of petroleum wastewater by microorganisms with a new way.For the chain alkyl hydrocarbon in crude oil, strains were isolated by screening and acclimatizing at the existence of diesel oil and kerosene. For the aroma hydrocarbon in crude oil, strains were isolated by screening and acclimatizing at the existence of phenol.

本试验我们针对石油中的链烷烃，分别以柴油和煤油为代表物进行筛选得到以降解链烷烃为主的菌种：针对石油中的芳香烃，以苯酚为代表物进行筛选得到以降解芳香烃为主的菌种：针对石油中的环烷烃，以环己烷为代表物进行筛选得到以降解环己烷为主的菌种。

Once this WMI filter is deleted, the other GPO's will not process until this filter is disassociated from them.

一旦此 WMI 筛选器被删除，其他 GPO 的筛选器将不进行处理，直到此筛选器与它们的关联被断开。

Once this WMI filter is deleted, the other GPO's will not process until this filter is disassociated from them.

一旦此 WMI 筛选器被删除，其它 GPO 的筛选器将不操作，直到此筛选器与它们的关联被断开。

In the present study, a gradated-combinatorial screening for antitumor -active microbial strains was carried out by the gradated combination of a 96-well plate lethality bioassay using brine shrimp and a flow cytometric bioassay using mouse tsFT210 cells.

为探索如何快速获取活性菌株的筛选模式，组合使用海虾生物致死法和tsFT2 10细胞的流式细胞术筛选模型，对从青岛前海和胶州湾潮间带海泥、动植物样品中分离的 162株海洋微生物，进行了抗肿瘤活性的分级组合筛选。

At the same time ,the cap of filter paper was used for improving transformation ratio. Leaf discs were transferred onto the media MS+ NAA(1mg/L)+6-BA(3mg/L)+Km(30mg/L)for regeneration resistant selction. Shoots from selection medium were cultured on medium MS +NAA(1mg/L)+6-BA(3mg/L)+Km(50mg/L) for selection again,and then on the media 1/2MS+NAA(0.2mg/L)+IBA(0.2mg/L)+Km(25mg/L)for rooting selectin.

共培养后把叶盘转入MS+ NAA(1mg/L)+6-BA(3mg/L)+Km(30mg/L)培养基上进行分化筛选培养。30天后可分化出不定芽，把不定芽转到MS +NAA(1mg/L)+6-BA(3mg/L)+Km(50mg/L)培养基上进行抗性芽的筛选，转到1/2MS+NAA(0.2mg/L)+IBA(0.2mg/L)+Km(25mg/L)培养基上进行生根筛选。

The objectives of the research were to screen molecular markers of sorghum resistant gene to the physiological strain No.3 of head smut with SSR. Bulked Segregation Analysis was applied in the study. Two segregation populations, restorer line population R population 2381R/Aisi and maintain line population Tx622B/7050B, were used in the research. The amplification bands of 94 pairs primers from 109 ones were clear and stable.

为了筛选高粱丝黑穗病抗病基因的SSR标记，以高粱抗病亲本(7050B、2381R)和感病亲本（Tx622B、矮四），及其杂交组合后代为材料，用CTAB法从叶片中提取高粱基因组DNA，通过SSR技术对高粱丝黑穗病3号生理小种抗性基因进行了初步筛选，结果表明：供试109对SSR引物中筛选出扩增条带清晰且稳定的引物94对。

If you click AutoFilter again to turn filtering back on, the previously set filters will be reapplied.

如果再次单击&自动筛选&以打开筛选功能，就会重新应用以前设置的筛选。

What makes these filters special is that they are based on the system clock so my "last month" filter will always filter to the previous month when the filter is reapplied.

这些筛选选项的特殊之处就在于它们是以系统时间为基础的，所以当我们选取&上个月&时，筛选的总是筛选功能运行时的上个月。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
