SOLID-STATE BATTERY WITH POLYACETYLENE ELECTRODE

The Li/LiI/(CHIy)x battery was fabricated by using fast ionic conduclor—LiI as the solid electrolyte has not been reported. The battery exhibited an open circuit voltage of 3.1~v and an initial short circuit of 7ma/cm~2. (CHIy)x can be used in the Li/I_2, battery as the roleof charge transfer complex. Experimental enemy density of 110Wh/kg was obtained based on the weight of (CH)x film (weight of (CH)x electrode: ca. 4mg, doping level:y=0.11).     

MULTI-FACET HOLOGRAPHIC LENS WITH PARALLEL AXES

The chara cteristics and manufacture method of multi-facet holographic lens with parallel axes are presented. with this lens some experiments have been carried out: a laser beam is converged simultaneously at multiple predetermined points, and an object is imaged simultaneously in the multiple positions. The lens can be used in following aspects: the manufacture of grating with multiple orientations, precise measuring of wavefront curvature of a laser beam. secret storage and communication, laser welding and drilling, multi-channel degenerate fourwave mixing and other interference techniques.     

DOUBLE-LAYER CHANNEL ROUTING WITH IRREGULAR BOUNDARIES

In the layout design of LSI chips, double-layer channel routng is used frequently. Usually the boundaries of a channel are parallel straight lines, But sometimes because of different sizes of cells, the boundaries have indentations. We hope some nets can be put into indentation areas to decrease the width of the channel.Two kinds of problems will be discussed in this paper. For one kind, the height of indentations is fixed; for the other kind, the height of indentations is adjustable. We propose two different algorithms for them.The algorithms were coded in PASCAL and implemented on VAX 11/780 computer. The computational results are satisfactory. Since some nets are laid inside indentations, the width of the channels decreases.

BIOPULPING OF WHEAT STRAW WITH PHANEROCHAETE CHRYSOSPORIUM

INTRODUCTIONThe trend of preservation of native forest and theincreasing consumption of paper and paper boardpromote both the use of recycled paper and thesearch of alternative non-wood virgin fibers. The useof wheat straw as a raw material for pulping andpapermaking seems to be an attractive alternative forcountries that have large plantations of wheat strawand are lack of forest resource.More and more interests are focused on thebiological treatment in the pulping process[1,2], whichis a…

SYNTHESIS OF PLASTIC PIGMENT WITH MULTIHOLLOW STRUCTURE

INTRODUCTIONIn recent years, seeded emulsion polymerization was often used to synthesis polymer/polymer composite particles used in many industrial field, such as in painting, print, coating and so on. Moreover, recently ,attention has been focused on the latex particle possessing hollow structure(1～4). For example, P(St -MAA) polymer particles was changed to those having hollow structure by alkali treatment, following by being cooled to room temperature, which was named as alkali/cool…     

高分子量尿激酶的放射免疫测定

本文介绍了高分子量尿激酶放射免疫分析方法的具体程序以及人尿中高分子量尿激酶的测量结果。标记采用Hunter等改进的氯胺T氧化法。碘化前,高分子量尿激酶用二异丙基氟磷酸失活,以避免生物机体中干扰物质带来的不良影响。失活的高分子量尿激酶与lmci~(125)Ⅰ反应2分钟,反应液全部上Sephadex G—50柱层析,经鉴定,标记率为35—40％。高分子量尿激酶放射免疫测量程序为:反应管中加入一定体积的缓冲液,30μl~(125)Ⅰ标记的高分子量尿激酶(约2×10~4cpm),标准品或待测样品,反应抗体。总体积0.3ml,摇匀,4℃保温24小时,然后力口入20μlSPA菌体试剂,混匀后于37℃保温0.5小时,3500rpm离心10分钟,测量沉淀放射性。用本法测定5例正常成人尿中高分子量尿激酶值为14.6±6.1iu/ml,灵敏度为0.8iu/ml尿。

酶法改性对蛋白质结构性质的影响及与酶特异性的关系——实验研究

研了酶作用对改性蛋白质结构性质的影响。实验结果充分表明:改性蛋白质的平均分子量与其水解度成反比关系。等电溶解度随水解度的增加成对数函数规律增加,极性与平均分子量成反比关系,柔性与平均分子量成负指数函数关系。这些均与理论研究结果一致。同时,憎水性随水解度的增加而呈反比例关系减小,而且与平均分子量成正比关系。根据以上结果,作者认为:改性蛋白质的平均分子量,极性,柔性和憎水性与酶作用之间存在明显的定量关系,可用来作为描述改性蛋白质结构性质的指标。
