The aerodynamic characteristics of the cuted tip rhombus wing and double-delta wing of middling sweepback angle and aspect ratio about sixty type are investigated by a numerical method based on Eular equations.

采用Euler数值计算方法，对60多种中等后掠角及展弦比的切尖菱形机翼、双三角机翼纵向气动力特性进行了计算、分析和比较，从中筛选出16种切尖菱形机翼、14种双三角机翼进行了全机高速风洞实验研究，给出了机翼的展弦比、前缘后掠角、根梢比及几何扭转变化对全机升力、阻力及俯仰力矩的影响曲线和数据分析，在此基础上提出了用于定量估算两类机翼纵向气动力特性的关系式及修正因子。

Computer was used to analyze the possible secondary cleavage sites on HPV11 E2 mRNA and to predict the secondary structures of substrate and ribozymes. According to the theory of Symons headhammer ribozyme, there are 32 sites to targetting sequences.

遵循Symons锤头状核酶结构和GUX剪切位点原则，靶序列存在32个剪切位点，通过计算机软件分析核酶的最佳剪切位点，并对底物及核酶的二级结构进行预测及进行相应基因生物学功能和基因同源性分析，筛选出2个锤头结构核酶。

The results show that this classifier has better efficiency performance in processing the flour and talcum powder in the range of 49 μm(300 mesh)-84 μm(180 mesh).

结果表明，该筛分机对处理粒度为49μm(300目)-84μm(180 目)的面粉和滑石粉具有较高的分级效率。

RT-PCR was used to detect the expressions of COL1A1 mRNA in 20 patients with idiopathic congenital talipes equinovarus.

采用半定量RT-PCR方法检测20例单纯性马蹄内翻足患儿下肢肌肉及肌腱组织中COL1A1基因mRNA的表达，根据COL1A1基因转录调控区-1 031 bp~+30 bp及第1内含子的序列，设计8对引物， PCR扩增后，采用变性梯度凝胶电泳技术筛查突变并测序。

The genetic diversity of 165 accessions of tartary buckwheat from 14 different geographical regions was analyzed using 20 informative primer pairs of AFLP markers.

Many patient taxonomist s from several European countries and America then sieved through litres of muddy gravel with microscopes and pairs of tweezers to see what treasures had been captured.

来自欧洲几个国家和美国的许多分类学家耐心地用显微镜和镊子对数以升计、沾满烂泥的沙砾进行筛分，来看看什么样的宝贝被铲了上来。

PGD is good for screening for specific genetic disorders such as cystic fibrosis and Tay-Sachs disease, and also can be used to select gender.

PGD适用于特殊遗传病的筛查，如囊性纤维化和神经节苷脂病，而且PGD也可以用于性别选择。

Just as Tay-Sachs has almost been wiped out in the decades since Ashkenazi Jews have tested themselves for the gene, a universal carrier screen, combined with preimplantation genetic diagnosis for carrier couples who want biological children, will eliminate a hundred others.

正如在Ashkenazi犹太人对自己进行基因试验后，Tay-Sachs疾病在数十年间几乎就被全部消灭一样，一种普遍的携带者筛查并结合那些希望获得亲生子女的夫妇们进行植入前遗传诊断将消灭众多其它遗传疾病。
