屈强

By mechanical test of the steel strip and simulation of strip deformation in tension leveling using finite element method,characteristic features of the strip were obtained,such as;high yield stress,high yield ratio and low plastic elongation as the basic reason of difficulty in tension leveling and shape control.

通过对全硬钢的力学性能的测定和拉矫变形行为的有限元仿真，发现屈服应力大、屈强比高以及断裂时塑性延伸小等特性是造成镀锌后全硬带钢拉矫困难和板形难以控制的根本原因。

Results show that the actual location of the cooling curve of the steel can be adjusted by regulating the strength of the steel and the yield strength ratio of the steel can be adjusted by controlling the cooling rate o...

分析认为调节钢的实际冷却曲线位置可调节钢的强度，调节钢在铁素体相变区内的冷却速率来调节钢的屈强比。据此对控冷工艺进行优化，使产品力学性能和组织符合技术要求和用户的要求。

The results indicate that finishing temperature and coiling temperature have more affects on yield ratio of HP345 steel.Yield ratio will increase when finishing temperature and coiling temperatrue reduced;It is obviously decreased when coiling temperature is equal to 650℃;it is obviously increased while coiling temperature is reduced to 580℃;it is lower and has less variation while coiling temperature is between 610℃ an...

结果表明，终轧温度和卷取温度对HP345钢的屈强比都有较大的影响，降低终轧温度和卷取温度，均使HP345的屈强比升高；卷取温度为650℃时，屈强比明显降低；而卷取温度降至580℃时，屈强比明显升高；卷取温度在610℃~630℃区间变化时，屈强比较低而且变化不大，同时钢具有较高强度。

Myopia: As axial length is too long, due to refractive eye refractive power of the system is too strong, resulting in 5 meters away from the formation of the parallel light rays focus before the retina.

近视眼：由于眼轴过长，由于眼球屈光系统的屈光力过强，以致5米以外的平行光线在视网膜之前形成焦点。

It is pointed out that for construction and supervision companies, they should study related specification, and recheck the yieldstrength ratio during sampling detection for steel bars.

施工单位和质量监督部门对受力钢筋的屈强比值在认识上存在误区，认为钢筋强度越高质量越好，忽略了钢筋的变形性能在钢筋混凝土结构中的作用。

The results show that: with the increase of tempered temperature, the quenched martensite transforms into the tempered martensite, tempered martensite + tempered sorbite and tempered sorbite; the strength of samples decreases continuously but yield ratio increases a little.

结果显示：随回火温度的升高，其组织由淬火马氏体逐渐转化为回火马氏体、回火马氏体+回火索氏体及回火索氏体；试样的强度连续下降，屈强比略有上升。

The steel selected for this investigation is spring steel 50CrVA for automobile in this paper,the appropriate duplex microstructure of lower bainite and martensite was obtained through isothermal quenching and low temperature tempeing heating treatment,then the effect of duplex microstructure and tempered troostite on strength-toughness of spring steel 50CrVA is compared.

以汽车用弹簧钢50CrVA为研究对象，通过等温淬火+低温回火热处理工艺获得适当比例的回火马氏体和下贝氏体的复合组织，并在此基础上比较复相组织和回火屈氏体对弹簧钢50CrVA 强韧性的影响。试验结果表明：在弹簧要求的HRC硬度在50~54范围内，在910℃保温30 min+360℃等温20 min淬火+300℃保温60 m in回火工艺得到复相组织的强韧性最好

However, because of greater increasing gradient of yield strength, higher material yield-strength ratio is achieved.

但由于其屈服强度增加的梯度大于抗拉强度增加的梯度，从而导致材料的屈强比升高。

Accelerated cooling (60℃/s) to 400℃ refines the allotriomorphic ferrite grain but retards the nucleation of intragranular ferrite with its distribution on prior austenite grain boundary as well as the volume fraction of bainite increased, and the strength increased but the elongation decreased and yield ratio became much higher on the steel.

当冷速增加到60℃/s且卷取温度为400℃左右时，铁素体在晶内形核受到抑制，铁素体沿原奥氏体晶界分布，晶粒得到细化，贝氏体体积分数增加，强度有较大的提高，但延伸率较低，屈强比较高。

There are secondary inflexions, particularly for the strong neuter singular and irregular nouns among other contexts, which are not described here.

这张表当然不是详尽的(哥德语存有次要屈折，尤其是对於强中性名词和不规则名词的次要屈折，它们在此不被讲述)，关於哥德语详尽的结尾的种类，如下所示。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
