筛选

It's very important to remember that a screening test is not diagnostic.

这是非常重要的要记住，筛选试验是不是诊断。

On the base of the principal factors selected from natural, social and economical conditions in Shenyang, 230 varieties virescence plants are analyzed and ranked, the paper picks out diaphysis trees, basic trees, ongoing expansion trees, adequately retained trees and selective trees from them, and the selection and adjustment program of basic trees and diaphysis trees.

在此基础上，采用园林专家咨询评价的方法，结合前人的研究成果及园林工作的实践总结，从生态适应性、观赏性、生态效能等方面全面系统的建立了沈阳市绿化植物的评价应用的综合指标体系，并根据沈阳市的自然条件和实际情况确定了主要的指标因子对沈阳市常见的230种绿化植物进行了综合评判和分级，筛选出最适宜的骨干树种和适宜的基本树种及宜继续推广的、可适当保留的或应淘汰的种类，提出了沈阳市绿化基调树种和骨干树种选择和调整的方案。

According to concerned papers ,we have chosen the way in which diquat dibromide is synthesized from 2,2-bipyridyls and ethylene dibromide. This paper makes further research into its technology, thus obtaining better synthesizing conditions.

本文在查阅大量文献的基础上，采用以2，2'-联吡啶和1，2-二溴乙烷为原料合成敌草快二溴盐的合成路线，并对其合成工艺进行了深入的研究，筛选出较佳的工艺条件。

R Dickey put together a team of electrical and chemical engineers and, together, they started looking at metals and metal alloys that are soft at room temperature.

ickey博士组织了一个由电气工程师和化学工程师组成的团队，然后他们开始筛选在室温下有着柔软特性的金属或金属合金。

At present, most genes were isolated by screening the cDNA or DNA library with theprobes homologous to sequences of dicot plants, and their functions were identified by themorphology of floral organs in transgenic plant.

目前研究手段主要是利用双子叶植物的同源序列来筛选水稻的cDNA文库，获取相关基因，然后根据转基因植物花器官的表型来验证该基因的功能。

In addition, we studied the ring-closing metathesis of the diene intermediates to access helicenes by screening a wild reaction condition.

我们还对RCM反应关环得到螺旋化合物的方法进行了研究，筛选得到温和的RCM反应条件。

To test the respirators fitness, we used quantitative fit test system to measure the fitness of the three models of new respirators worn by real person. The testing method is to use a differential mobility analyzer to select the particles of 40nm in diameter. N95 respirators are capable of filtering out almost all 40nm particles, therefore, the 40 nm particles measured within the respirator would be considered due to the leakage caused by poor fitness.

口罩密合度是使用定量密合度测试组合系统以真人分别配戴三款五年口罩A、B与C和同样型号新口罩来测试其密合度，测试方法主要是利用差异电移动度分析仪筛选粒径为40nm的微粒，而N95口罩的特性几乎可以完全过滤40 nm的微粒，所以口罩内量测到40nm粒径的微粒可被认定是泄漏造成。

Objective To search a new and effective method for screening differential expression genes based on microarray expression data.

目的 基于微阵列表达数据，探索差异表达基因筛选的新的有效方法。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
