During overpassed 20 more years, as a kind of new experimental technology, small punch test for measuring small size specimens has been developed to evaluate the material mechanical properties of in-service equipments. It is already used to determinate the elastic modulus, yield stress, plastic properties, endurance strength, ductile-brittle transition temperature, fracture toughness, creep properties, plasto-viscous properties and so on.

20多年以来，采用小型试件的小冲杆试验技术来测量在役设备材料的各种力学参数已经取得了很大进展，这个方法已经用来确定材料的弹性模量、屈服强度、塑性性能、抗拉强度、韧－脆转变温度、断裂韧度、蠕变性能和黏塑性性能等各种力学性能。

OA was caused in the rabbit by resecting the cartilage between diaphsis and condyle of proximal tibia.

针对临床中大量的继发性膝关节OA病例，孟和教授强调了生物力学在病因学、病理学及治疗学中的重要地位：&尽管有酶类及免疫反应的参予降低了关节软骨的屈服强度，但要磨损到骨质外露却离不开应力的作用&。

Silicon alloy of silicon is also a good agent, in steel by adding an appropriate amount of silicon can increase the steel yield strength, flexibility and acid-fast performance; if the content is too high, then reduce the plasticity and toughness.

3硅硅也是一种较好的合金剂，在钢中加入适量的硅能提高钢的屈服强度、弹性及抗酸性能；若含量过高，则降低塑性和韧性。

Although all the codes note that the angel range between strut and tie has significant influence on the designing and checking result, and corresponding specifications of angle between strut and tie have been made, yet none of the specifications relate such factors as the ratio of web reinforcement, stirrup yield strength and the compress strength of concrete, etc.

虽然各规范都认识到拉、压杆之间的夹角取值对设计和验算结果的影响，并对此做了相应的规定，但都没有明确地将腹板的配筋率，腹板钢筋的屈服强度和混凝土的极限抗压强度等因素联系起来，因此有必要对此做进一步深入的研究。

The thermally stable capability and mechanical property of the deuterated foam above were analyzed by the differential scanning calorimetry, dynamic mechanical analysis, stress-strain behavior analysis, and other methods. The results showed that the glass temperature or the decomposed temperature for the prepared foams is 100℃-120℃,or about 400℃, respectively. However, there was the irreversible change in the foams at between 50℃ and 100℃.

结果表明：1泡沫玻璃化温度在100℃-120℃，裂解温度在400℃左右；2在50℃-100℃之间和一定作用力下，泡沫存在不可逆的形变；3室温下(22℃)，随着密度增大，泡沫弹性模量增大，损耗因子减小；在泡沫密度为20 mg/cm3-160 mg/cm3时，弹性模量为2MPa-10MPa，屈服强度为0.01MPa-0.12MPa，破裂形变为5%-35%。
