青海高原春小麦籽粒蛋白质积累规律研究

分析了阿勃,青春５３３,青农４６９、青农４５２等四个春小麦品种（品系）在青海西宁地区籽粒蛋白质相对含量的变化规律和蛋白质绝对含量的积累进程,结果表明,从开花至成熟,籽粒蛋白质相对含量的变化呈“Ｕ”型曲线,并以花后籽粒发育初期含量最花,花后３１天左右是该地区春小麦籽粒中蛋白质相对含量最低的时期。不同品种在花后不同时期蛋白质相对含量各不相同;籽粒蛋白质绝对含量的积累过程呈“Ｓ”形曲线,可用概率转换方程     

Stimulation of glucagon and inhibition of insulin secretion evoked from carotid baroreceptors.

The influence from carotid baroreceptors on portal immuno-reactive glucagon and insulin levels and on arterial plasma glucose concentration was studied in vagotomized cats by sectioning of the sinus nerves. Such a complete elimination of the afferent baroreceptor discharge caused a prompt and pronounced increase in the glucose and glucagon levels, whereas the insulin concentration significantly decreased. The role of vascular barorecptors in the hyperglycemic response to hemorrhage is discussed.     

Genetic control by the HLA region of the immune response to factor VIII in hemophilic patients]

In 10 sibships of haemophilic A patients, every one including 1 haemophilic brother with an antibody to factor VIII and 1 haemophilic brother without antibody, pattern of HLA segregation was analysed. All sibships were HLA haploidentical or different and not HLA identical. This fact suggested a linkage between the major histocompatibility complex and an "Ir" gene to factor VIII.     

Effect of insulin on immunological phagocytosis by macrophages.

It was shown that, in physiological concentrations, insulin enhances, in vitro, the immunological phagocytosis of sensitized sheep erythrocytes by cultured mouse peritoneal macrophages. Insulin seems to stimulate macrophage phagocytosis as a cholinomimetic agonist by increasing the intracellular levels of cyclic GMP.     

Pyrogen fever in rabbits pretreated with p-chlorophenylalanine or 5, 6-dihydroxytryptamine.

The hyperthermic effect of a bacterial pyrogen has been studied in rabbits pretreated or not with p-chlorophenylalanine or 5, 6-dihydroxytryptamine. The results obtained indicate that a selective reduction of cerebral 5-hydroxytryptamine levels by these drugs do not significantly affect pyrogen hypertermia.     

计算机辅助螺纹钢孔型设计系统的开发及应用

型钢孔型设计是制定型钢轧制工艺的重要内容之一.传统孔型设计过程以人工经验为主,其计算繁琐,原材料消耗大.为提高生产效率,通过对螺纹钢延伸孔型系统、精轧孔型系统及成品孔型的构成和设计方法的分析,结合螺纹钢孔型系统的基本设计理论和实际生产经验,对以往孔型设计过程中所使用的数学模型、经验公式等进行了修正,并以结构化程序设计方法为基础,采用可视化编程工具Visual Basic6.0建立了计算机辅助螺纹钢孔型设计系统.试用效果表明,缩短了新产品的设计周期,降低了轧机能耗和生产成本.     

高硅沸石中二元物系表面扩散系数的预测

用动力学蒙特卡罗（Kinetic Monte Carlo，KMC）方法模拟客体分子单组分及双组分混合物在高硅沸石（Silicalite）分子筛中的扩散，与分子动力学（Molecular Dynamics，MD）方法的模拟结果及Maxwell-Stefan（M-S）方程计算对比说明KMC方法的合理性，而由真实的体系性质获得正确的跳跃频率值及合适的晶格模型是获得正确计算结果的关键，且一旦由单组分研究获得正确的跳跃频率值及晶格模型，便可直接移用至多组分体系的KMC模拟中。     

白马鸡配对期两性行为的比较

2003年4月和2004年4月在四川省稻城县著杰寺采用瞬时扫描取样法对野生白马鸡(Crossoptilon crossoptilon)配偶行为进行了研究.结果表明,白马鸡配偶中雌、雄个体全天伴随活动,无特殊情况不会分离.在不受其他个体干扰的情况下,配偶移动时雌性多在前并控制移动方向.雌、雄鸟间距离平均为(1.75±0.03)m,在雄性驱逐其他个体时间距最大.在全天行为记录中,雄性警戒的时间最多,之后依次为取食、移动、驱逐、站立、休息和其他行为.雌性在一天中行为时间分配依次为取食、移动、休息、站立、警戒和其他行为.驱逐行为完全由雄性承担.两性共有行为中雄性用于警戒的时间显著高于雌性(P<0.05),用于取食、休息的时间显著低于雌性(P<0.05),用于移动和站立的时间与雌性差异不显著(P>0.05).
