采用等温蒸发法研究了四元体系K+、Na+∥CO32-、HCO3--H2O 35℃相平衡及平衡液相的密度、电导率、折光率和pH值，测定了该四元体系在35℃条件下平衡溶液的浓度及物化性质。

In addition, the maximum velocity in larvae was significant higher than those in pupae and adults. In vitro inhibition studies of larvae AChE indicated that the I50 values of 20-d larvae were higher than those of 10-d larvae when treated with eserine, malaoxon and carbaryl, respectively, suggesting that AChE in 20-d larvae was less sensitive to the inhibitors.

通过对幼虫AChE离体抑制作用测定表明，毒扁豆碱、马拉氧磷和西维因对20d龄幼虫的抑制中浓度I50均高于10d龄幼虫，说明20d龄幼虫体内的AChE对3种抑制剂的抑制作用更不敏感。

The effects of different temperature and initial gasses ratio in Si-rubberbag on celery storage were studied,quality parameters including weight loss rate,etiolation rate,decay rate,respiration rate,changes of the concentration of oxygen and carbon dioxide in Si-rubberbag,cell membrane permeability and coarse-fiber contents were mensurated.

研究了不同温度以及硅窗袋内不同初始气体浓度比例对芹菜贮藏效果的影响，测定了芹菜贮藏过程中失重率、黄化率、腐烂率、呼吸强度、袋内O2、CO2含量、细胞膜透性、粗纤维含量等指标的变化，结果表明：温度对芹菜贮藏效果影响显著，但15℃与5℃环境下芹菜贮藏效果相差不大。

In order to test the anesthetic effect of Eugenol to Cyprinus carpio Linnaeus,Eugenol was dissolved in the water and diluted in different concentrations for the test.

为测定丁香酚对鲤Cyprinus carpioLinnaeus的麻醉作用效果，将丁香酚溶于水配制成不同浓度溶液进行试验研究。

The characteristic and difference of flow in porous media between the pseudo-plastic fluids and the expansile fluids was described in detail. The experimental pressure drop measurements were made in a packed bed under a variety of conditions, and the variation of the friction factor with the Reynolds number was obtained. Corresponding to the flow resistance in a nonporous channel, the flow resistance in porous media can be divided into Darcy resistance and Forchheimer resistance as well. The experiment data was divided into Darcy regime, transitional regime and Forchheimer regime in accordance with the Reynolds number.

实验测定了不同浓度聚丙烯酰胺溶液在五组填充多孔介质中流动的压降-流量关系，绘出了阻力因子随Reynolds数变化的关系曲线；按照将流动阻力分为层流粘性阻力和惯性阻力的观点，将多孔介质流动阻力分为Darcy阻力和Forchheimer流动阻力；参考有关文献，将实验区域按Reynolds数范围分为Darcy流动、过渡流动和Forchheimer流动。
