The results showed that under the given experimental conditions,the surface layer with richiron and poor copper was formed in the surface worn region of the semimetallic friction material,the depth of organic ingredient pyrolysis caused by friction heat in worn surfaces was atout 0.35mm; the semimetallic friction material containing 15%-20%of Cu had better wear-resistance,and can form a even and continuous transfer film of copper; crack peeling was the importantmechanism of the counterpart.

半金属摩擦材料具有摩擦系数稳定，耐磨性好，对环境污染小和对偶件表面损伤小等优点，但其在摩擦热和界面应力等因素作用下，表层会发生弹性变形，塑性变形，元素扩散，组分转移和摩擦化学反应等现象，因此，利用扫描电子显微镜X射线能量色散谱和差热－热重分析，对铜纤维增强的半金属摩擦材料与灰铸铁滑动摩擦表面层的特性作了分析研究，考察了表面层特性对摩擦损行为的影响。

Joint Time-Frequency Analysis is a new-style theory in Signal-Analysis, which combines the signals' characters in time domain with those in frequency domain. For reflecting the integral character, JTFT possesses good effect in analyzing unstationary or time-changing signals.

联合时频分析方法是一种新型的信号分析理论，它结合了信号在时间域与频率域的特性，反映了信号频率随时间变化的综合特性，在分析非稳定、时变信号方面具有很好的效果。

Natural marble have lamination to be different with their ventilative, characteristic of ink completely.

天然大理石因其具有纹理各异，透气，透水的特性，使人造地板砖无法替代和比拟，因而倍受推崇，然而这种透气透水的特性，也使天然大理石泛黄，泛碱的通病无法彻底根治。

Objective To determine the oviposition responses of Anopheles sinensis to bacteria A4, Aeromonas sp. and Enterobacter sp. and whether or not the three strains attracted the mosquitoes, providing theoretical and experimental evidence for the application of the three bacteria in the intervention of malaria. Methods Blood?fed and held for 48-60 h, copulated female An.

目的 具吸引作用的细菌或其挥发物能提高按蚊与杀虫或抗疟工程细菌接触的机会，为此，拟测定中华按蚊对A4细菌、气单胞菌和肠杆菌的产卵反应特性，以明确3种细菌对中华按蚊是否具有吸引特性，为应用这3种细菌开展阻断疟疾传播研究提供理论和实验依据。

In addition to these etch pits,it is also found that there is another kind of etch pit for both Schaake and Chen etchants,but neither of them threads the HgCdTe epilayer.

除了穿越位错外，在两种腐蚀方法揭示出的腐蚀坑中都还存在着一种不具备穿越特性的腐蚀坑，两者在密度分布以及界面处密度增值方面具有相同的特性，但前者在宏观缺陷附近密度出现明显的增

It has been proved that surface confined quinones can greatly impove the electrocatalytic activity for ORR.

本论文中研究的氨基蒽醌聚合物修饰电极，与其它方法得到的醌类修饰电极比较，具有性质稳定、制备过程简单、活性点位浓度高等优点，而且同时具有类似聚苯胺的长链结构和蒽醌官能团的特性，为制备具有高氧还原催化活性的蒽醌修饰电极的研究提供了新的思路。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
