Windows环境下光伏水泵报价系统的实现

该文介绍了在Ｗｉｎｄｏｗｅ３．１环境下．利用ＭｉｃｒｏｓｏｆｔＣ（＋＋）及其基本类库（ＭＦＣ）开发光伏水泵报价系统的方法。该方法采用了面向对象技术，使软件具备可重用性。同时，ＭＦＣ类库的使用使复杂的Ｗｉｎ－ｄｏｗｓ应用程序的编程接口变得更容易。该方法对其它工程报价问题也具借鉴意义。     

样条能量配点法分析高层框架结构

本文利用样条能量配点法来分析高层框架结构。先将框架模拟成等效性质的正交异性连续体,然后选取样条函数与连续函数的乘积来构成该连续体位移函数,最后用能量配点法来求解。     

Induction of hemopoietic chimerism in the caprine fetus by intraperitoneal injection of fetal liver cells

Summary Intraperitoneal injection of allogeneic liver cells from 43-day-old male fetuses into normal 60-day female goat fetuses resulted in persistent hemopoietic chimerism in surviving recipients without clinical evidence of graft-versus-host disease. Transplantation of normal fetal liver cells into preimmunocompetent goat fetuses affected with -D-mannosidosis may provide an alternative strategy for evaluating hemopoietic stem cell transplantation in the treatment of human lysosomal storage diseases.     

A new indolic antiauxin, α-(5,7-dichloroindole-3-)isobutyric acid: its chemical synthesis and biological activity

Summary A new potent antiauxin, -(5,7-dichloroindole-3-)isobutyric acid has been synthesized and shown to inhibit auxin-mediated elongation ofAvena coleoptiles and to stimulate root growth of rice seedlings. Its activity is stronger than -(p-chlorophenoxy)isobutyric acid and is comparable to that of 2,3,5-triiodobenzoic acid, which are typical antiauxins.     

切削刀具倒棱刃口挤压力的理论计算

根据试验观察．揭出了刀具刃口带负倒棱时的切削模型。在此模型中,刀具刃口 存在一个“金属死区”。以新模型为基础．采用能量法,对高温、高应变率下刀具刃 口的挤压力进行了理论计算。所做工作的特点是：１）在材料变形分析中计入了挤压 层金属绕过刀具刃口时的过剩变形;２）进行有关材料变形与物理特性的计算时,考 虑了温度与应变率的影响。利用新研制的压电式切削测力仪进行验证试验,其结果表 明,理论计算值与实测数据较好一致。     

空间机构的位置分析

本文以“基本方向”确定空间机构中各构件的位置,并基于“基本方向”之间的关系以及机构的环路封闭条件,建立了机构位置分析的数学模型。将优化技术和求解非线性方程组迭代技术结合起来,提高了解决问题的可靠性及效率。     

The contents of the pygidial gland of the primitive antNothomyrmecia macrops (Hymenoptera:Formicidae)

Summary The principal constituent of the pygidial gland ofNothomyrmecia macrops is 3,7-dimethyloct-6-en-2-one, a substance not previously identified in insects. Also identified were 2,6-dimethylhept-5-enal, 2-nonanone, indole, -dodecalactone, and the hydrocarbons pentadecane, heptadecane, heptadecene and heptadecadiene, all in low nanogram quantities.
