不变钢

On this theory, a framework is designed which can change the spinal position but to fix the ring position to have a fixedness balloon heightness, through which the spinning tension can keep stability ,at the same time, all kinds problem during spinning course can be reduced and the yarn quality can be assured.

在这个理论基础上，我们设计了一套通过改变锭子位置而钢领板位置不变的装置来使气圈的高度不变，从而达到纱线张力的稳定，从而减少成纱过程中因为张力问题而产生的各种问题，减少断纱，提高了成纱品质。

There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums, since, if the length of a pendulum changes, its time of vibration changes.

不过也有一两个例外，例如有一种钢叫做殷钢(从"invariable"一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

There are one or two exceptions. There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums , since, if the length of a pendulum changes, its time of vibration changes.

The experiments of light-weight steel frames with four types of different semirigid joints were carried out.

在钢框架分析和设计中，一般都假定梁柱之间没有相对转动，梁柱之间夹角不变的完全刚接或者梁柱之间不能传递弯矩，只能独立发生转动的理想铰接。

This article describes the design on work roll wobbler of hot strip tandem mill, by finite element optimization analysis, in the case of without change of motor power, the material of work roll is change from steel roll to malleable cast iron, the strength of wobbler can reach the design requirement.

介绍热带钢连轧机工作辊扁头的设计，通过有限元优化分析，在电机功率不变，工作辊材质由钢辊改为可锻铸铁的情况下，扁头强度满足设计要求。

By the experimental results obtained from both dilatometric and magnetic methods, it has been found that addition of 1～2% C_o maymarkedly enlarge the temperature range of low expansion coefficient forinvar steel.

根据膨胀试验和磁性试验的结果，加入1～2％的钴会显著的扩大不变钢最低膨胀系数的温度范围。

Carbon, excellent carbon steel systems, low-alloy system (including high-built steel), bridges, steel non-tax price of lowered 200 yuan / ton, container steel system does not tax price of lowered 150 yuan / ton, ship plate prices remain unchanged.

普碳、优碳钢系统、低合金系统、桥梁钢不含税价下调200元/吨，容器钢系统不含税价下调150元/吨，船板价格不变。

There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums, since, if the length of a pendulum changes, its time of vibration changes.

不过也有一两个例外，例如有一种钢叫做殷钢(从&invariable&一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.

由于提取钢圈轮廓比提取车轮橡胶轮廓容易，而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆，所以在本文中，我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影，然后利用射影变换保持交比不变的性质求出车轮轮廓。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
