查询词典 rolling

A meso mechanical analysis has been conducted on a hot-rolling steel of 16MnR toinvestigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under the maximum normal stresses with various directions. The analysis results show that, when the elongated voids due to the decohesion of the inclusions from base material are loaded subsequently, the local high stress and strain concentration around the voids and their interactions promote the growth of voids.

对热轧钢中的长条形初始损伤孔洞承受不同方向最大正应力时的后续损伤演化和断裂过程的细观有限元力学分析研究表明：热轧钢中的长条形夹杂物与基体剥离后形成的长条形孔洞在后续加载中，其周围产生的局部高应力应变集中及其相互作用，使孔洞长大。

A method of path planning based on rolling windows with function of normal distribution density for mobile robot was presented in this paper.

在原有滚动窗口路径规划方法基础上，提出基于正态密度函数的滚动窗口路径规划方法。

The mountains and the colors are not infected vicissitudes of life are still stubborn with green green; silly eastward of the river has not only failed to become like a mirror-like bright and quiet, but autumn in the rolling dry moving slightly turbid; river plants desolately miserable miserable all day Wangziningmou Although there is no yellow autumn bleak Akigusa decay, the situation could be a cheerless place a layer of more people unnecessarily autumn coolness.

群山并没有染上沧桑的颜色，依然固执着苍翠的青绿；痴心东流的河流不但没有变得如镜般明亮宁静，反而在连绵的秋雨中稍显浑浊燥动；河边的水草凄凄惨惨，终日枉自凝眸，虽无秋风惨淡秋草黄的衰败，可冷冷清清的境地更使人徒添一层秋的凉意。

最后通过退火清净性、润湿性能、储存稳定性及轧机实验，对产品综合性能进行了考察与评价。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
