覆层

As with series resonance, the greater the resistance in the circuit the lower the Q and, accordingly, the flatter and broader the resonance curve of either line current or circuit impedance.

黑色金属极易受到氧化或其他化学作用的侵蚀，因此必须用某种方式加以保护。一种常用的办法就是通过称为电镀的处理过程使金属表面覆上一层锌。

This course will introduce the systematic design methodology of the SiP technologies, partitioning, integration, Flip-Chip, wire bonding, muti-stacks, high density sticking, measurement. Moreover, the signal and power integrity analysis will be introduced here.

介绍SIP生产中使用的系统设计技术，分割、整合、覆晶、线接合、多层堆叠、高密度黏著技术和量测方法；再介绍讯号与电源完整分析。

"It requires a positive, a core made of refractory material and an outer layer of wax."

用耐火材料做成实心的正像，外面覆以蜡层。

One trend to minimize the risk associated with this issue is to use closures coated or laminated with fluorocarbon film.

趋势之一，要尽量避免与此相关的问题是要利用封包覆或层压氟碳膜。

The coating time of slurry, the annealing temperature, and the adsorption of merbromin have significant influence on the optical transmittance of nanoporous film.

浆料涂覆次数、退火温度、汞溴红吸附对纳米多孔膜层的光学透过率影响显著。

It is discovered that the oxide thickness increases as the starting titanium iso-propoxide increases while other parameters are kept exactly unchanged, and accordingly, the peak redshifts initially and then blueshifts; Moreover, as the mass of silver nitrate increases, the peak redshifts and the absorption band goes wider; the synthetic temperature exerts no effect on the final shape and size of the prepared nanoparticles, only tolengthen the needed reaction time.

结果表明：二氧化钛壳层的厚度随异丙醇钛量的增加而不断增加，其紫外一可见吸收峰先红移，然后蓝移；随着硝酸银的质量的增加，银核的直径增加，并可观察紫外一可见吸收峰的红移，峰宽也逐渐变宽；合成温度的变化对包覆纳米颗粒的大小及形状没有明显的影响，只是改变了合成所需要的时间。

Autumn morning, you see, there is a thin layer of frost covered in the above, like wrap a layer of granulated sugar.

秋天的早晨，你去看，有薄薄的霜覆在上面，像裹了一层砂糖。

In comparison with the conventional method of coating on the tool surface, carbide powders were coated with boehmite sol when dispersed in the mixture of boehmite sol and ethanol. The coated powders were then dried, separated, and hot-pressed. The sol preparation techniques were optimized in experiments and the property of the sol was studied at the same time.

本文从提高硬质合金刀具的耐磨性、探索新型刀具涂层方法入手，突破了在刀具表面进行涂层的传统方法，提出了用溶胶－凝胶法在硬质合金碳化物粉末表面涂覆一薄层氧化铝陶瓷制成复合粉末，然后热压制备刀具材料的新方法，开发成功一类新型的陶瓷涂层硬质合金复合刀具材料。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
