使表面粗糙

When the minority carrier life of PS decreases, the irradiative centers on surface of PS increase, which lead to decreasing of photoluminescence efficiency.

另外，原子力显微照片表明长时间的腐蚀使多孔硅表面层被化学腐蚀，从而降低了多孔硅表面的粗糙度。

Such failure is due to the accumulation of toner than age at first, so that the toner can not produce a position to enter the toner, and the waste toner in粉仓will continue to "squeeze" caused by "powder leakage" phenomenon, Then, as the toner contains纸灰, fiber and other filth, more rough, and long cartridge friction, and more tight, the pressure increases, eventually the surface of photosensitive film cartridge has been worn away, cartridge will be ruined.

产生这种故障的原因是起先废粉堆积过满，使再产生的废粉无法进入废粉创仓，而废粉仓中的废粉也会不断"挤"出来而产生"漏粉"现象，接着，由于废粉中包含着纸灰、纤维等脏物，较粗糙，与硒鼓长时间摩擦，而且越来越紧，压力越来越大，最终将硒鼓表面的感光膜磨掉了，硒鼓就损坏了。

By sanding the split leather surface to roughen it up.

是通过打磨分割层皮革的表面，使它变粗糙而得到的。

Normally some coarseness will happened after sandblast treated ,which help to enhance the adhesive power.

通常喷砂处理均会使金属表面产生一定程度的粗糙度，这对漆层附着力的增强有很大的帮助。

Research show titanomagnetite with fine grain high magnetic coercitive force is mian mineralogy of binding sinter mix,and magnetic force between sinter mix and roughened surface improve to bind sinter mix on the sifting bar.

研究表明：高矫顽力、细粒级的钛磁铁矿是粘结物料的主要矿相，它们与粗糙表面的筛杆之间的磁相互作用使粘结程度日益加重。

The product of Resmax Skin Series uses pure natural plant Yuanbao essential oil, and contain bioactivators like Vitamine E which can keep skin celluar soft, spring and active, and all kinds of trace elements and so on, which can substitute new-born cell for dead cell constantly; it accelerates metapolism and strengthens secretion of epithelial cells and improves tarnish, tough skin, maintains completeness of intercelluar substances; desalts splash, eliminates wrinkle, and makes skin tightened, smooth and high resiliance.

Finally, the experimental setup of MR intelligent boring bar was built on the CA6140 type lathe. The experimental results show that the method can suppress the chatter efficiently and can improve the surface quality of workpieces significantly, whose roughness has decreased from 10 μm to 1.5 μm.

最后，在车床CA6140上搭建了磁流变智能镗杆的颤振抑制实验系统，实验结果表明，变结构刚度方法能够快速高效地抑制镗削过程中产生的颤振，并且使加工表面的粗糙度Ra从10μm降至1.5μm，大幅度提高了加工表面质量。

The electroformed copings and interfacial area were examined by SEM and EDS analysis. Results: Surface roughness increased by sandblasting, O content had not been greatly improved by preoxidation, the coping surface formed a porous structure after applying gold bonder. The gold and porcelain combined tightly, mechanical chimera and simple diffusion of Al, O elements were observed in interfacial area.

结果：喷砂可以增加金沉积表面的粗糙度，预氧化没有使氧元素含量得到很大提高，涂布金黏结剂后金沉积表面形成了多孔样的结构：金瓷结合紧密，可见明显的机械嵌合结构，金瓷界面出现了铝、氧元素的单纯扩散。

It can create a natural sebum membrane on the surface of the skin with only one, to avoid dryness and external stimulation to the skin, to adjust the regeneration period of the skin and make the skin moisturized and elastic, to defy the oxidation of the sebum and prevent veins, dim complexion and roughness of the skin, to reduce the harm to the skin causing by the active oxygen created by the ultraviolet radiation, to soften the front end of whelks and unblock the drainage of the sebum in the pores.

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
