The structural and mechanical properties of ring-spun yarn have been studied comprehensively. The relationships between yarn linear density, yarn twist, and the relative yarn structural and mechanical properties have been obtained. Through statistical analysis of yarn linear density, twist, and strength of 200 groups of pure cotton yarn, and considering some influence factors, such as carded or comed, application of long-staple cotton, experiential functions of yarn relative strength with yarn linear density and twist have been obtained.

对环锭纱结构力学性能进行系统研究，得出环锭纱的相关力学性能参数与纱线线密度和捻度的关系；通过对从工厂收集的200组纯棉纱线线密度、捻度、强力等数据的统计分析，并综合考虑纱线线密度、是否精梳、是否使用长绒棉等因素，得出了线密度和捻度与纱线强力相对值的经验函数关系。

Web-based application system of geometric error compensation aims to broaden error compensation technology by using network. SMART-CNC machine tool has been chosen as the object of experiment.

"Mimas looks like, ah, a natural version of the Death Star in Star Wars because one of its surfaces is almost completely dominated by a giant crater. Ah, had...the object which caused the crater been slightly bigger, Mimas would have been totally destroyed, and by now, it would have been assimilated into Saturn's rings."

"土卫一看上去简直就像是电影星际《星球大战》中的死星的原型，因为它的其中一面几乎完全被一个巨大的陨石坑所占据，如果造成这个坑洞的物体再大一点的话，土卫一就会完全被摧毁并被吸入土星的光环中。"

BACKGROUND: Several cardiac ion channel genes have been implicated in monogenic traits with a high risk of sudden cardiac death. Mutations or rare variants in these genes have been proposed as potential contributors to more common forms of SCD, but this hypothesis has not been assessed systematically.

背景：数种心肌离子通道基因和高危心源性猝死的单基因特性有关，这些基因的罕见突变被认为是SCD更常见的潜在促进因素，但是这一假说没有被系统的评价过。
