Objective:To improve the value of multi-slice spiral CT in the diagnosis and treatment of small intestinal lymphomas.

目的：应用多层螺旋CT动态强化扫描对小肠淋巴瘤患者进行前瞻性研究，旨在提高多层螺旋CT在小肠淋巴瘤诊治中的价值。

The majority of keratin mutations are dominant acting and mostly involve mis-sense or small insertion/deletion mutations clustering at the ends of the rod domain of the keratin molecule.

目前报道的基因突变点集中在角蛋白1A螺旋起始区和2B螺旋末端的高度保守区，基因突变方式多数为错义突变，偶有小片段插入或缺失突变。

Under the excitation of 488 nm light beam of argon ion laser source, single suprahelical species could be observed with the aid of a common microscope due to the strong scattered light emitted by the suprahelical species. By capturing the RLS images of the single suprahelical species with a cooled charge coupled device camera, and analyzing the RLS data, herein an RLS imaging method of DNA was proposed based on the linear relationship between the counts of suprahelical species in the detection focus plane and the concentration of DNA in nanograms.

在488nm 氩离子激光光源的激发下，单个超螺旋聚集体的散射光可以通过普通显微镜观察到，用冷却型电荷耦合器对此单个粒子的RLS信号进行成像和分析，发现在聚焦平面上检测到的超螺旋粒子的个数与溶液中纳克级的DNA浓度成正比，基于此建立了一种测定DNA的方法。

Independent front suspension was by coil springs and wishbones, while at the rear the rigid axle was suspended on coil springs with radius arm location.

独立前悬架是由螺旋弹簧和叉，而在后方刚性车轴中断了螺旋弹簧与半径手臂的位置。

This paper presents the separate resolution of free rigid body motion into tree wrench motion s.

Enter asymmetric spiral turning to the left. If you have enough energy to loop, enter SAT to the right at the moment you would do the loop. Using the asymmetric spiral as lead in to tumbling results in very powerful tumblings (the pilot is passing the glider vertically after first turn over the canopy).

方法二：：先进入左侧的非对称螺旋，当你具有足够的能量进入筋斗的时候，向右侧进入土星此时即进入后筋斗；使用非对上方称螺旋进入的后筋斗非常有力，飞行员可以垂直的从伞的上方翻越

This kind can assign easy arrangement of transaxle of welling versed in etc..

由于偏移距正的存在，使主动齿轮螺旋角大于从动齿轮螺旋角(图5—4)。

You have isolated a plasmid DNA that is a closed circular molecular 1050 bp in length with 5 negative supercoils.

请问这个DNA分子的连接数、螺旋数、扭曲数、以及超螺旋密度是多少？

The 60s helix spaned from Glu-61 to Tyr-67 in imidazole cytochrome c while it spaned from Glu-61 to Glu-69 in cytochrome c.

与cyt c中的60s螺旋延伸到Glu-69情况不同，在Im·cyt c中60s螺旋仅延伸到Tyr-67。
