Using the method we calculate the 〓 elasticdifferential scattering cross section, excitation differential scattering crosssection, and excitation cross section of electron collision with 〓 We transform the electron and molecule problem into electron problemby Born-Oppenheimer approximate. Mr Rossi, Dr. the Flinders University ofSouth Australia, calculated electron collision with molecule, but theexchange term he used become bigger and bigger as incident energyincreases, it is unreasonable, besides, the potential of electron and nucleus heused is somewhat rough. At present we correct these two terms. The potentialconsists of static potential, exchange potential, polarization potential.

电子与分子的碰撞过程的相互作用势主要是由静态势、交换势和极化势三部分决定的，这里对这三部分在动量空间中进行分波展开，推导出易于计算的表达形式，根据这些公式，并参考Rossi的弹性碰撞程序编写了计算电子与分子碰撞激发截面的程序，利用程序计算出势能矩阵元，通过求解Lippmann-Schwinger方程求得T矩阵元，便可求得散射截面。

In Zhong Shan's artworks,"Double images" art has man's appearance and figure as the subject, and expresses in the form of "diptych". The two works are placed side by side, and can be compared and observed, expressing the meaning of two in one and the relationship between concepts such as the internal and the external, ego and alter ego, real image and virtual image, sense and sensibility, spirit and material, double image and corresponding and so on. His art shows that the artist is reflecting the contemporary society from a special view angle and that the symbols bearing the weight of human social and historical culture and contemporary ideology occur in various changing characters, showing the colorful world of today.

在艺术家钟山的艺术中，"双相艺术"是指以人物等容貌、外形为表现主体，以双联成对形式这种新的阐释方式呈现，它们相互并列对置，可进行比较、审视，共同表达一体两面、内在与外在、本我与异我、实象与虚象、理性与感性、精神与物质、双像与对应等理念的关系，传达出艺术家以另类视角审视当代社会，体现那承载着人类社会和历史文化脉络及当代流行意识形态的符码，形形色色交织演绎在万千变化的形象上，展现着今天这个缤纷万象的世界。

The standard applied modes of geometric flatness in new GPS(geometrical product specification),including the duality principle and common operation technology in new GPS system,and the expression,algorithm,data processing issues of the theoretical,specification and verification model,were investigated.

The dominant male sterility was expressed normally in the new Taigu genic sterile wheat carrying the intergenomically translocated Ms2, and the female fertility mechanism in its male sterile plants was normal as well. Observation of the chromosome configuration at meiosis of pollen mother cells of the young ears of the sterile plants showed that they were euploid plants (2n=42). No configurations different from those of the Taigu geneic sterility gene located at the original locus were noticed of the Ms2 intergenomically translocated back into the common wheat.

所获携带易组Ms2基因的新型太谷核不育小麦其显性雄性不育特性表达正常，且雄性不育株的雌性可育机制正常，对不育株幼穗花粉母细胞减数分裂期染色体构型的观察可见其为整倍体(2n=42)，尚未发现回归普通小麦的易组太谷核不育基因与原位点的太谷核不育基因有不同的表型。

The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.

①单纯球囊损伤可成功建立典型家兔血管狭窄模型，操作方法简单，经济实用；②以VSMC增殖、迁移为主的内膜增厚以及以ECM降解、合成与再分布所致的血管重构是导致受损血管狭窄的根本原因；③通心络能明显抑制VSMC的增殖、迁移和ECM降解、合成，阻止血管内膜增生和血管重构，防止受损血管狭窄；该作用可能与其减少和阻止PDGF-BB的产生和活性，以及抑制MMPs的表达和恢复MMPs/TIMPs平衡有关；④通心络能显著抑制球囊损伤后血管内膜增生和血管重构，可能与其保护血管内皮，改善内皮功能，增加血清NO含量有关；⑤通心络抑制内膜增生和血管重构，减轻受损血管狭窄，还可能是通过抑制NF-κB的活化途径而起作用的。

The GFAP is a specific marker of astrocyte, its expression is more higher in the activity astrocyte, and finally the GFAP become the main composition of scar formations. The S -100 is a kind of acidity, dissolubilites, low molecular quantity and calcium hydronium conjugated protein, and it is mainly existed in neuroglial cell and schwann cell. It can promote the growth of axon, glial hyper-plasia and nerve divide and calcium's stability inside of cell, thus regulatin g the shape and metabolism of astrocyte . The quantity of S -100 protein and the degree of ischemia have direct proportion .

胶质纤维酸性蛋白是星形胶质细胞的特异性标记物，在活性星形胶质细胞中GFAP的表达相对更高，且最后GFAP成为胶质疤痕的主要成份。S-100蛋白是一种酸性、可溶性、低分子量的钙离子结合蛋白，主要存在于胶质细胞和雪旺细胞中，它可促进轴突生长、胶质增生、神经分化和细胞内钙的稳定，从而调节星形胶质细胞的形态和代谢。S-100蛋白与缺血的程度是成正比的。

No man was ever so poor that he could express all he has in him by words, looks, or actions; his true knowledge is eternally incommunicable, for it is a knowledge of himself; and his best wisdom comes to him by no process of the mind, but in a supreme self- dictation, which keeps varying from hour to hour in its dictates with the variation of events and circumstances.

没有人是永远这么差，他可以用文字表达他所有，他也期待，或行动，他的真正的知识是永恒的静默，因为这是对自己的知识，以及他的最佳智慧来给他的过程中没有心，但在最高法院自默，这可防止小时不等小时在其与事件和情况的变化驱使。

(1) The skull slot needling integrated with language training and single language training showed improvement on lingual function and neural function patients with aphasia following the apoplexy, however, the skull slot needling combined with language training group seemed more effective than the single language training group;(2) The skull slot needling treatment can obviously improve the scores in clinical neural function, and prompt the ability of speaking language expressing, accelerate the comeback of audition comprehension, enhance the ability of iterance, quicken the reading speed and improve the veracity of reading;(3)The comeback of lingual function can be benefit for the intercourse between patients and doctor and family numbers, can build up the self-confidence of conquerring diseases, can cooperate with doctors, all these factors can affect morbid curative effect and prognosis.
