升巨散对实验性血小板减少症的治疗作用研究

采用水提醇沉法将升巨散制成冲剂,对实验性血小板减少症的治疗,表明升巨散具有升高外周血小板数量之功效,差异显著(P<0.15).相继在出血时问、凝血时间和24h 血块收缩实验中,也间接证实本品有升高外周血小板数量之作用。又在骨髓象检查中,发现升巨散能提高骨髓之巨核细胞及血小板数量,差异显著。本品 LD_(50)及95%可信限为70.88±2.62g/kg。

Study on Approach for Computer-Aided Design and Machining of General Cylindrical Cam Using Relative Velocity and Inverse Kinematics

Cylindrical Cam Mechanism which is one of the best eq uipments to accomplish an accurate motion transmission is widely used in the fie lds of industries, such as machine tool exchangers, textile machinery and automa tic transfer equipments. This paper proposes a new approach for the shape design and manufacturing of the cylindrical cam. The design approach uses the relative velocity concept and the manufacturing approach uses the inverse kinematics concept. For the shape desig n, the contact points betw...     

动力总成悬置支架拓扑优化研究

采用结构拓扑优化方法,对动力总成悬置支架进行了优化.在最优拓扑结构的基础上进行结构修改后,一阶固有频率明显提高,而重量有所减小.从加强筋的优化结果来看,在平行于一阶弯曲振型方向上布置加强筋,可获得较好的效果.研究表明,在产品的概念设计阶段采用拓扑优化方法,能给产品的详细设计提供一个很好的基础.

The Development and Application of Combined Thermoregulatory Mathematical Models

Thermoregulatory mathematical models have being developed for more than half a century and obtained more and more wide application. Among them, the "engineering-physiological" thermal models, which correlated closely to the man-machine-environment system, are the ones that developed most rapidly and have been widely accepted by thermal physiologists and environmental control engineers.This paper attempts to outline briefly the development and application of such kind of thermal models, discusses how to further develop and apply various combined thermal models in practice, and puts forward four respects of suggestions for establishment and modification of combined thermal models of man-clothing-cabin environment.     

河南的红菇科真菌资源的研究（Ⅱ）

红菇属（Ｒｕｓｓｕｌａ）是红菇科（Ｒｕｓｓｕｌａｃｅａｅ）的一个重要的属。本文依据在河南山区采集的标本,鉴定、整理出红菇属的种类有３１种,其中食用菌２４种、药用菌４种、毒菌５种。此外,它们多是菌根菌,与林业有着密切的关系,还有不少种类的子实体中含有抗癌物质,具有抑制肿瘤的作用。
