时效

The results show that the corrosion rate of the aged alloy increases with aging time until1 193 h and thenceforwards decreases again. The T4 alloy shows the lowest corrosion rate, and the F alloy exhibits the highest corrosion rate.

结果表明，时效时间为193小时之前，合金的腐蚀速率随时效时间增加而增加，之后有所降低；T4态合金的耐蚀性最好，F态最差。

In respect of the nature of guarantee period, there are a few views in the theory and practice field including period of prescription, period of exclusion, and period of divesting of right. Guarantee period does not conform to the features of period of prescription and period of exclusion, guarantee period should be "the period of divesting of right clause" promised by the guarantee contracting parties.

关于保证期间的性质，理论界与实务界有种种观点，包括诉讼时效说、除斥期间说、失权期间说，保证期间不符合诉讼时效与除斥期间的特征，保证期间实质上为保证合同中当事人约定的&失权条款&上的期间。

The results show: TiC particulates can act as nucleates of α-Al and enter into α-Al during solidification. They also can act as nucleates of S' phase during ageing, there are a lot dislocations around TiC particalates, which accelerate ageing process of 2024/TiC composites.

研究表明：TiC颗粒能作为α—Al形核核心，在凝固过程中进入α—Al基体；在时效过程中，TiC颗粒可以作为S′相的衬底，其周围存在大量位错，加快了复合材料的时效进程。

A new model is presented for the physically-consistent description of plastic instabilities referred to PLC effect. The model takes account of two competing processes during the DSA on micro-scale: the additional pinning of diffusing solute atom on mobile dislocations and the unpinning of the mobile dislocation with the aid of thermal activation.

建立了一个基于动态应变时效过程中热激活机制和二阶应变梯度空间耦合方式的宏观唯象模型，该模型刻画了材料内部在微细观尺度上彼此协同和相互竞争的两个过程：溶质原子对可动位错的时效钉扎和可动位错在热激活辅助下的挣脱。

The tensile properties of under-aged 3J21 alloy at room and low temperatures were studied on a universal tensile teat machine. Moreover, a metallographic microscope and X-ray diffractometer were used to analyze the metallographic structure and physical phase of the alloy in a cold rolled and under-aged state. By employing a transmission electron microscope the structure of the alloy under the above-cited two states was observed and the X-ray diffraction results being verified.

在万能拉伸机上对欠时效态3J21合金室温及低温条件下的拉伸性能进行研究，并采用金相显微镜、X射线衍射仪对冷轧状态和欠时效态的金相组织及物相进行分析，采用TEM观察两种状态的组织和结构，验证了X射线衍射结果。

Mg-3Zn-xY alloys become age-harden as aging time rises. As Y content increases, MgZn phase precipitated in the Mg-3Zn-xY alloys decreases gradually.

时效处理过程中，随着时效时间的延长，Mg-3Zn-xY合金中均出现了时效析出现象；随着Y含量的增加，Mg-3Zn-xY合金中MgZn析出相逐渐减少。

The results show that the damping capacity of Zn-22%Al remains constant for ageing temperature below 80℃, the warm rolling temperature. Traces of Ce and La can improve the damping capacity of water quenched and warm rolled Zn-22%Al, and decrease the reduction of the damping capacity of Zn-22%Al during ageing at 150℃.

结果表明，经水淬后80℃温轧的Zn-22%Al合金在低于温轧温度下时效时，其阻尼性能保持稳定；微量Ce，La的加入，提高了经水淬后80℃温轧的Zn-22%Al合金的阻尼性能，减缓了经150℃时效后阻尼性能的降低。

抗辩权产生主义的立法模式在法律逻辑上可行，但难以充分发挥诉讼时效的债权信用保障功能，与诉讼时效的理论基础不完全吻合，仍然可能对交易安全构成伤害。

The legislative models of legal effect of limitation of action of producing right of defense is good in theory and logical, but in this model limitation of action can＇t play a full game in maintaining debt trust,and it is not accord with the theory foundation of limitation of action.

抗辩权产生主义的立法模式在法律逻辑上可行，但难以充分发挥诉讼时效的债权信用保障功能，与诉讼时效的理论基础不完全吻合，仍然可能对交易安全构成伤害。

Ti element is found to aggregate, forming an ultra-fine reaction layer in the active filler metal-ceramic joint after 260℃/24hr aging treatment. Two different-color intermetallic compounds are observed in the interface of active filler metal-copper. One is Cu6Sn5 , which is closer to active filler metals;the other is Cu3Sn, which is closer to the copper substrate.

接合后之试片，经260℃/24hr时效反应后，发现Ti元素聚集於焊料与陶瓷界面处形成一层极薄的反应层且发现在焊料与铜之反应界面有了明显颜色不同之两层介金属层生成，靠近焊料端的介金属层为Cu6Sn5，Cu片端的是Cu3Sn；而Cu6Sn5化合物从原本未时效10μm成长为25μm。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
