Genetic diversity among 7 populations of Trillium tschonoskii were analyzed by using inter SSR and amplified fragment length polymorphism molecular markers. The results were as follows:(1)ISSR: 12 out of the 100 primers showed consistent banding patterns and amplification, a total of 135 bands were produced with an arrange of 250-2500bp, 46 of which (34.07%) were polymorphic.

应用锚定SSR和限制性片段多态对7个延龄草居群的遗传多样性进行了分析，结果如下：从100个引物中筛选出12个ISSR引物，在250-2500bp之间共扩增出的135个条带，其中多态性带为46，占34.07％。

The sorter can accurarely grade pearl rice,normal rice,big crushed rice and small crushed rice by their particle,special structure and plane rotary movement of the sieve,It can improve the trimness degree of the rice so that the commodity can get higher value,It is also suited to other grain mqterial.

该机利用大幅度的平面回转运动，利用整米和碎米在粒度上的差异和独特的机体结构。配备精确的冲孔筛板将白米中的特一米、一般米、大碎米、小碎米准确分离，提高白米的整齐度，创造更高的商品价值。

By the damage evolving relation proposed the flexural process of the trisection specimens of wet-sieved and fully-graded concrete was numerically simulation.

根据本文提出的损伤模型和损伤参量演化关系，分别对湿筛混凝土和全级配混凝土试件进行了三分点加载数值模拟。

Abnormal chromosome was detected in 17 fetuses. Among them, trisome 21, trisome 18, trisome 13, Turner syndrome, Klinefelter syndrome, short arm deletion of chromosome 18, and inverted chromosome 9 were detected in 8, 3, 1, 1, 1, and 2 fetuses, respectively. Abnormal chromosome was found in 5 out of 8 fetuses who received serum screening. Ultrasound showed abnormal chromosome in 11 fetuses.

共诊断17例胎儿染色体异常，其中21三体8例，18三体3例，13三体1例， 1 Turner综合征1例，Klinefelter综合征1例， 18染色体短臂微缺失1例，9号染色体臂间倒位2例(1例来源于母亲)。17例中有8例进行了唐氏儿血清学筛查，5例异常，11例超声检查胎儿有结构异常。

The ultrasound prenatal screening of trisomy 18 has important clinical value.

产前超声筛查对诊断18三体综合征具有重要的临床意义。

Prenatal ultrasound is effective at detection of fetuses with trisomy 18 and find out those who need further genetic testing.

超声检查是一项安全、无损伤的产前检测技术，近年来在产前筛查和出生缺陷领域广泛应用。

It turned out that 7 cases were found with trisomy 21.4 cases among the 9916 negative-screening cases were born with trisomy 21, according to the analysis of the chromosome karyotypes in peripheral blood.

在筛查阴性的9916例中，出生DS患儿4例，经外周血染色体核型分析证实为21三体。

Micrognathia also was more common defects in trisomy 18. The vast majority of fetus with trisomy 13 and 18 can be detected by routine ultrasound examination.

小下颌、叠指畸形也是较常见的畸形，见于18三体。18三体和13三体的畸形在超声筛查中检出率较高。
