Compared with that of magnetic Fe3O4 liquid, the magnetization saturation of the ferrum magnetic liquid is increased by more than 21%.

复合磁性液体的饱和磁化强度比Fe3O4磁性液体的饱和磁化强度提高21%以上。

The result makes clear: EThe tensile strength of TFE film increases somewhat along with the addition of drawing speed, and rupture outspread rate reduces;ETFE to succumb filmily somewhat along with the addition of drawing speed the addition that intensity follows drawing rate and increase somewhat, but the 2nd succumb intensity increases not big;ETFE to succumb filmily meet an emergency follows drawing rate increase somewhat, the 2nd succumb the amount of tangent and stretch model that meet an emergency reduces;ETFE film somewhat and model of the 2nd flexibility measure those who follow drawing rate to increase show downtrend, quantity of secant flexibility model and quantity of the 3rd stretch model do not have apparent change.

结果表明：ETFE薄膜的抗拉强度随拉伸速度的增加略有增加，而断裂延伸率随拉伸速度的增加略有减小；ETFE薄膜的屈服强度随拉伸速度的增加而有所增加，但第二屈服强度增加不大；ETFE薄膜的屈服应变随拉伸速度的增加略有增加，第二屈服应变则略有减少；ETFE薄膜的切线弹性模量以及第二弹性模量随拉伸速度的增加呈下降趋向，割线弹性模量和第三弹性模量则没有明显的变化。

API specification states that the yield strength of body of oil line pipe is evaluated by flated sample cut from pipe.

API标准规定，采用管体取样压平试样的屈服强度，表征输油管管体屈服强度。

For UOE tube with low springback stress,the Bauschinger Effect makes the yierld strength of flated specimen be lower than that of UOE tube body which received expanding process.In this case,Using plated sample as the body representation is safe and conservative.

对UOE管，由于其弹复应力低，包申格效应使压平试样的屈服强度低于经强力扩径强化的管体屈服强度，因而这种表征是偏于安全的。

The result s indicate that there are synergy effect s between pile and foam under flatwise compressive st rength and fabric piles f ractured under flatwise compression. The flatwise compressive and shear st rength decrease with increasing of the pile height . The flatwise compressive st rength increases as exponent with increasing of the foam density.

结果表明，三维间隔连体织物泡沫夹层结构复合材料承受平压载荷时，芯柱和泡沫存在协同效应；平压载荷作用下主要发生芯柱断裂破坏；随着芯柱高度增加，平压、剪切强度均减小；随着泡沫密度增加，平压强度近似呈指数增长。

The results showed the change of residual flexural strength was controlled by oxidation of carbon phase.

结果表明，残余抗弯强度的变化受C相的氧化控制，残余抗弯强度与失重率之间的变化规律符合指数关系。

利用TaqDNA聚合酶的 5' 3'核酸外切酶活性降解特异性杂交于模板上的荧光标记探针，导致荧光强度的改变，通过检测荧光强度分析PCR扩增产物。

Heat treatment of steel is a manufacturing process commonly used to transform a relatively inexpensive, low strength and formable steel into a high strength material.

前言 在将价格相对低廉、强度较低的可成型钢转变为高强度材料过程中，钢材热处理是一种普遍采用的制造工艺。

Based on the Peterson type formula and the Topper type formula, two formule of effective stress concentration factor are developed.

本文考虑了材料、受载形式、尺寸、错位量、焊接残余应力以及焊趾根部短裂纹对错位板节点疲劳强度的影响，在Peterson公式和Topper公式的基础上，分别建立了两个估算这类节点疲劳强度的有效应力集中系数的公式。

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。
