提高抽送黄河水用泵寿命的重要途径

从保证抽送黄河水用泵（以下简称抽黄泵）的寿命和工作可靠性出发，提出了抽黄泵性能参数选择的原则：限制抽黄泵的单级扬程Ｈ；限制抽黄泵单级扬程Ｈ与转速ｎ的乘积Ｈｎ值。并给出抽黄泵性能参数的Ｈ·ｎ－Ｑ关系曲线和泵的比转速ｎ＿ｓ与单级扬程Ｈ的关系曲线。     

多片生成元集分形介质层的波反射

该文研究了多片任意生成元集（即更加广义的Ｃａｎｔｏｒ集）分形介质层的垂直入射及斜入射的反射透射谱，给出了这种情况下的一般自相似递推谱算法．这种算法能得到任意级次、任意结构及任意入射角条件下的振幅谱．文中所给出的一类反射谱是一种准周期自相似谱，有望在电子对抗、薄膜光学及光电器件等重要领域获得应用．     

Evaluation of the hepatotoxicological effects of a drug in an in vivo/in vitro model

Both in vivo and in vitro models have certain disadvantages for the study of the chronic hepatotoxicity of drugs. The aim of this work was to evaluate a new approach based on an in vivo/in vitro model. After chronic in vivo treatment of rats with Vincamine and Vindeburnol (an eburnamenine derivative which exhibits hepatotoxic properties in man) liver cells were isolated, and functional and metabolic disorders (metabolic utilization of fructose and protein biosynthesis) were studied to determine injury. The results showed no modification of blood parameters, but a direct relationship between the dose of Vindeburnol administered in vivo and the metabolic disorders observed in vitro, evidencing the high sensitivity and reliability of this model.     

Adrenocortical metabolism and plasma corticosterone in soman intoxicated rabbits

Summary The organophosphate neurotoxin soman produced impairments in adrenocortical RNA and protein metabolism. Fasciculate and reticular cell RNA and protein contents were supporessed with sublethal to acutely lethal dosages (20, 30 and 40 g/kg, s.c.) during the acute excitatory phase of intoxication and at 6–8 h post injection. All three dosages produced ca 90% inactivation of plasma cholinesterase. A transient elevation of plasma corticosterone occurred with 20 g/kg soman whereas there was a protracted increase with 30 g/kg. Corticosterone was not significantly elevated with 40 g/kg, but death occurred at 13±4 min. Thus, the magnitude and/or nature of soman-induced metabolic impairments does not appear to prevent adrenal activation.Supported by US Army Medical Research and Development Command Contract DAMD 17-81-C-1202.
