為了進一步加強國內外軸承工業的技術交流與合作，加快新產品新技術推廣，推動軸承工業的發展，經國家主管部門批準，由中國北京機械工程學會主辦北京世紀佳業展覽有限公司承辦的「 2006中國北京國際軸承工業展覽會」於2006年8月30日9月1日在北京中國國際展覽中心舉辦。 -
The concrete used in testing bridge is monitored and some performance at definite age including compressive strength, splitting fensile strength, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure by mercury porosimetry are tested. these performances are compared with that of concrete which designed by traditional method. the results show that mechanical properties of concrete designed by high durability concrete proportion and traditional method meet require ment at any age, however, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure of the former are better than the latter, so high durability concrete is economic benefit
對試驗橋用混凝土的質量進行監控，並成型試件測量所需齡期內的抗壓強度、劈裂強度與抗凍融、抗鹽凍、氯離子擴散系數（ dcl - ） 、抗碳化等耐久性能指標及孔結構，並與傳統混凝土進行對比研究，結果表明:高耐久性混凝土及按傳統配合比設計的混凝土的力學性能均能滿足相應齡期的要求，但前者的抗凍融性能、抗鹽凍性能、抗碳化性能、 dcl -和孔結構明顯優於後者，並具有明顯的社會經濟效益。 -
After the batch tests, geotechnical characteristics of cation contaminated clay are studied. it is found that adsorbed cation can induce significant changes in the mechanical properties of clay. : to determine diffusion parameters of cations through clay, some laboratory tests are carried, out via horizontal and vertical diffusion tests
在粘土吸附性的基礎上，對粘土吸附污染物離子后的基本土工特性（塑性、滲透性、強度等）進行試驗研究，總結了粘性土在滲濾液的長期作用下其土工特性的變化趨勢。 -
Under the careful retrospection and analysis on the previous and recent experiments about mechanical behavior of nanocrystalline metals performed by almost main investigators, the dislocation and atomic diffusion is believed to contribute hardly to the deformation of nanocrystalline alloy, and a model based on thermal activation process was applied to fit the experimental data of nanocrystalline ag
結果表明，納米晶金屬ag的不僅具有比粗晶ag高2 - 6倍的拉伸和壓縮強度，而且在大范性形變階段顯示了極低的加工硬化和應變速率敏感性。結合位錯理路和非晶合金形變特徵，提出納米晶金屬ag的塑性變形主要由於晶界滑移貢獻。 -
In this thesis, a semi - classical model of the force on an atom is used to describe the motion of a two - level atom interacting with a standing wave laser field. the velocity dependent force and momentum diffusion are derived through optical bloch equations by using the matrix form of the continued fraction technique. by investigating the dynamic properties of atoms in laser field, we can control and manipulate the mechanical motion of an atom
本文利用半經典理論，從二能級原子在激光駐波場中所滿足的運動方程出發，推導出密度矩陣元所滿足的遞推關系，利用矩陣連分數方法求解出密度矩陣元，從而求出依賴于原子運動速度的光壓力與動量擴散系數，通過討論原子在激光場中的動力學行為，為原子在激光場中被囚禁、形成原子列陣以及可控制的量子態，從而為量子信息處理提供理論基礎。 -
As experiments reveals, the moisture diffusion, heat conduction and mechanical response in polymers are mutually affecting behaviors
有試驗發現，高聚物中濕分、溫度和應力是相互影響的。 -
Some previous experiments have showed that cavities had more efficient gettering than p - diffusion, mechanical damage and ion implantation. most of studies about cavities gettering are concentrated on the peculiarity of cavities gettering metal impurities intentionally into silicon wafer from the viewpoint of basic study. this technique especially applied to low - contamination process, how ever, has not been carefully studied, which should be important to the semiconductor manufacturing
而過去的工作多集中在從基礎研究的角度研究氦微孔對有意摻入金屬雜質的矽片的吸除特性，對無意引入的低濃度金屬雜質的器件吸雜效果的研究卻非常少，這方面的研究是氦微孔技術走向實際應用的必經之路。 -
It is indicated that mechanical milling dramatically enhances the activity of the powder and thus making the solid state diffusion between the two elements much easier. on the other hand, green samples made of deep milled powders are hard to sinter to their densification
實驗結果表明，機械研磨由於顯著提高粉體活性而促進ni ， ti元素間的擴散相變，研磨程度越深，對固態反應相變的促進作用越大。
