It builds the whole liquid-cooling system mainly by the design of the liquid-cooling decalescence boxes(improve its bottom material from aluminium alloy to pure copper, enlarge its volume, better cooling effects, and strengthen pressurization), by the operations of cooling effect about the heat exchanger worked by its temperature adjustability of the ribs(diffuse the heat fleetly owing to the excellent diathermancy of the material of the ribs ,make effective diathermancy owing to ribs outside areas, and drive the heat of the ribs away by the fans), and by the water pump made up of the piezoelectric ceramic with the excellent performance-no electromagnetism interference, little cubage, little noise, light exterior, light weight, low consume, high flux, replacing the mechanical pump.

在液冷散热器的研究中，主要通过对液冷吸热盒设计不断地改进(使吸热盒底部的材料从铝合金变为纯铜材料，其整个体积有所变大，但其散热效果明显变好，且密封性得到了极大地加强)，综合地运用换热器中肋片的壁面温度调节作用产生的散热效果(肋片材料优良的导热性，快速地扩散了热量：肋片较大的与流体接触的表面积，使传热更加充分，对流热阻大大减小；再利用风扇对肋片上的热量进行吹散)，利用性能优良的压电陶瓷泵(该泵机电性能稳定，具有无电磁干扰、体积小、噪音小、外型轻薄、重量轻、低能耗。、高扬程等优点。)代替机械泵作为驱动源，搭建了整个散热系统。

For the COG joint subjected to thermal storage test at 80 oC for 1000hours, the resistance raises from 0.48 to 1.26Ω while in the sample, the resistance raises from 0.73 to 1.52Ω; all test results fit the reliability requirements. But the reason of increment is not only NCF material degradation cause, but also the bump is elastically. Therefore elastic bump resile caused the resistance to increase after pressing. Consequently I used another two samples which is not thermal aging compared to test samples, the results were show bump resistances increasing about 65%, its come form elastic bumps itself.

COG试片经过80oC约1000小时之后观察电阻上升情形，一片约从0.48Ω上升至1.26Ω另一片从0.73Ω到1.52Ω也符合可靠范围内，但是上升的原因不完全是胶材劣化导致，因为凸块本身具有弹性，所以在压合之后还会回弹造成电阻上升，因此会使用另两片未热时效的试片来比较，得知结果大概65％的电阻上升是来自本身具弹性导致。

The changes mentioned above make the hard membranous sac, the nerve root, the vertebral artery and the gangliated nerve stressed and stimulated, which produces a series of clinical symptom and form the cervical spondyolsis; On diagnosis, the CT is superior to the plain film of X-ray, but the latter is still the foundation and the preference.

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。

At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.

针对大庆油田扶、杨特低渗透油层砂岩孔隙喉道的大小和形态以压实再生型片状、弯片状喉道分布较广，压实、缩小型细喉道型，微孔不可流动的孔隙体积所占总孔隙体积的比例较大的特点；及储层泥质含量高，注水开发中压力敏感性强、微孔隙欠饱和及水锁效应显著，导致流体渗流阻力增大的问题，本文采用室内实验、理论推证和矿场应用相结合的方法，研究、分析了流体非线性渗流特征，更深刻地揭示出小孔包围大孔的机理及产生原因，并提供了改善开发效果的新的技术方法，取得如下成果：选择不同渗透率的低渗透、特低渗透岩心，进行了气、水和油单相渗流实验，揭示出当岩心渗透率不同时，油层内的流体呈现出拟弹性流变、过渡流变、塑性蠕变三种流变区，从而打破了岩心的绝对渗透率与通过岩心流体性质无关的观点；同类特低渗透岩心的水驱油两相渗流实验表明，两相渗流区较窄。
