The main findings of the empirical analysis include: 1 The decisions concern the choices of auto ownership, mode to work, and auto use were made simultaneously and interrelatedly. 2 The decline in correlation between the choices of auto ownership and use as the number of vehicle increase indicated that to own multi-vehicles in not necessary due to the demand for auto use. 3 Both price elasticity and income elasticity for auto ownership are low. This evidence implies that auto has become a kind of necessity for household. Therefore, the effect of decreasing the tendency of auto growth by means of increasing the cost of owning auto would not be significant. The price elasticities of auto use are between -0.48 and -0.78. 4 There are same underlying factors influencing auto ownership, mode to work, and auto use including: parking time at residential location, accessibilities to work location by auto and transit, auto use unit cost, and the percentage of auto use for work. These factors indicate a direction for the formatting of future automobile policies.

本研究以台湾地区之家户个体资料从事实证分析，实证分析之主要结论如下：1小汽车持有数量、工作者工作运具选择、与小汽车使用量等选择间确有相关与联立性存在；2小汽车持有数量选择与小汽车使用量选择间之相关性会随小汽车持有数量的增加而降低，显示选择持有多部小汽车并非完全基於小汽车使用之需要；3小汽车持有之价格弹性与所得弹性均偏低，显示小汽车已成为民生必需品，欲以提高小汽车持有成本之价格手段来抑制小汽车持有，并无法竟其功，小汽车使用需求之价格弹性则在-0.48与-0.78间；4影响小汽车持有数量、工作者工作运具、与小汽车使用量等选择主要之相关或共同因素包括：家户附近停车状况、私人运具与大众运输工具之工作可及性、小汽车单位使用成本、与小汽车工作使用比率等，以上这些影响因素可为日后小汽车相关政策的研拟提供一方向。

Mg-Al oxide catalysts were prepared by co-precipitation method, used ammonia as the precipitating agent. The catalytic performances of these materials were investigated in the gas-phase Aldol condensation of acetone to isophorone. The structure and surface properties of the catalysts were characterized by means of XRD, XPS, ICP, TG-DTA and TPD.

Interaction of 8B7 spectrin with Dynactin(P62),Stathmin,Emerin, Lamin A and found Lamin A was examined by means of co-immunoprecipitation test by me.

我藉免疫共沉淀检测了8B7血影蛋白与Dynactin(P62)、Stathmin、Emerin及LaminA间的关系，结果只见8B7和LaminA可以在体外共沉淀。

The silicon-acrylic latices with core-shell structures were prepared by means of a"two-stage"emulsion copolymerization. The effect of constituents and proportion of core and shell parts on the properties of latex film were investigated, and their applications in water-borne wood coatings and elastic coatings were explored. The results indicate that wood coating and elastic silicon-acrylic coatings with good performance and zero VOC content can be prepared by suitable design of structure of silicon-acrylic latex particles.

通过&两段&乳液聚合的方法合成了具有芯／壳结构的硅丙乳液，研究了芯／壳乳液粒子结构及组成比例对聚合物漆膜性能的影响，并探讨了芯／壳乳液在水性木器涂料及弹性涂料中的应用，结果表明，通过对硅丙乳液粒子的结构设计，可以获得性能优良的零VOC含量的木器涂料和弹性硅丙涂料。

This paper deals with the surge protection of a 220kV H—GIS and analyzes the effects of metal oxide surge attesters on reducing the incoming lightning overvolrages by means of numercal method Meanwhile, there is a kind of over-voltagey which may be rather critical for GIS, e·g·the switching surges with extremely high frequeuly produces by GIS-G switching-off of some loadless duses.

本文讨论220kV混合式GIS变电站过电压保护，用数值计算方法分析氧化锌避雷器对降低过电压的作用，并讨论了有一种类型的过电压可能对GIS要求更为严格，即在主回路中用GIS隔离开关切除空母线引起某些高频操作过电压，因此在绝缘配合时要相应考虑。

It has been found that the cation exchange on diffusivity may play the role in different ways for different zeolites. When the diameter of the diffusant molecule is much smaller than the pore or cage size of the zeolite, the influence of exchanged cations is mainly by way of altering the electric field intensity (or the density of electric charge), the large the Z/r of the exchanged cations, the smaller the diffusivity; while the diameter of the molecule is apporsi- mately equal to the pore or channel size of the zeolite, the exchanged cations may affect the diffusivity by means of blocking up or narrowing the channels of the zeolite.

金属阳离子交换对扩散的影响表现为：当扩散分子的直径比分子筛孔道直径小得多时，交换阳离子以改变分子筛内部电场强度或电荷密度的方式影响扩散速度，阳离子的Z/r越大，扩散系数越小；当扩散分子直径与分子筛孔道直径相近时，交换阳离子则因堵塞或窄化孔道而改变分子的扩散速度。
