应用高速离心快速中和吸收法检验混合斑中精斑血型物质

本文介绍了应用高速离心与快速中和吸收相结合的方法,检验混合斑中的精斑血型物质。试验证明,只要精斑与阴道分泌物斑的混合比例不小于1∶4,就能正确检出精斑的血型物质。一般情况下,本法可排除阴道分泌物血型物质干扰。

氯气吸收装置的改造

氯气吸收装置是加氯车间必备的装置,改造前的氯气吸收装置在使用过程中存在吸气量小、结晶阻塞、暴管喷溅碱液等不足之处,经过多次试验,在该装置吸入口加装引风机,并对喷淋设备进行重新设计焊装,改造后运行效果良好。

一种简便实用的型煤固硫效果测定法

提出了一种简便实用、易于实施的测定型煤固硫效果的方法——管式炉燃烧吸收中和法。测定结果重现性较好。此外,作者还研制了一种型煤用复合固硫剂,在1000℃下,其固硫率可达66%以上,助燃效果可达5～7%,且成本又不高,值得推广。

Modeling Chemically Reactive Flow of Sutterby Nanofluid by a Rotating Disk in Presence of Heat Generation/Absorption

In this article we investigate the flow of Sutterby liquid due to rotating stretchable disk. Mass and heat transport are analyzed through Brownian diffusion and thermophoresis. Further the effects of magnetic field, chemical reaction and heat source are also accounted. We employ transformation procedure to obtain a system of nonlinear ODE's. This system is numerically solved by Built-in-Shooting method. Impacts of different involved parameter on velocity, temperature and concentration are described. Velocity, concentration and temperature gradients are numerically computed. Obtained results show that velocity is reduced through material parameter. Temperature and concentration are enhanced with thermophoresis parameter.
