The objective of the current study is to investigate the importance of entropy generation and thermal radiation on the patterns of velocity,isentropic lines,and temperature contours within a thermal energy storage device filled with magnetic nanoencapsulated phase change materials(NEpCMs).The versatile finite element method(FEM)is implemented to numerically solve the governing *** effects of various parameters,including the viscosity parameter,ranging from 1 to 3,the thermal conductivity parameter,ranging from 1 to 3,the Rayleigh parameter,ranging from 102 to 3×10^(2),the radiation number,ranging from 0.1 to 0.5,the fusion temperature,ranging from 1.0 to 1.2,the volume fraction of NEpCMs,ranging from 2%to 6%,the stefan number,ranging from 1 to 5,the magnetic number,ranging from 0.1 to 0.5,and the irreversibility parameter,ranging from 0.1 to 0.5,are examined in detail on the temperature contours,isentropic lines,heat capacity ratio,and velocity ***,the heat transfer rates at both the cold and hot walls are analyzed,and the findings are presented *** results indicate that the time taken by the NEpCMs to transition from solid to liquid is prolonged inside the chamber region as the fusion temperatureθf ***,the contours of the heat capacity ratio Cr decrease with the increase in the stefan number ste.

次氯酸钠可作为棘球绦虫的杀虫卵剂

内蒙古畜牧科学 1990年第3期11卷 45-46页

作者： p.s.craig 朱兴全

过去已进行了大量的研究试图寻找能杀灭棘球绦虫虫卵及其它带科绦虫虫卵的有效化学试剂(Nosik,1952;Meymarian & schwabe,1962;parnell,1965;Laws,1967;Owen & stringer,1984)。schwabe(1984)这样概述:棘球绦虫虫卵(以及相关的带科绦虫卵)对所有常用的杀菌剂如福尔马林、来苏尔、次氯酸钠、碘化合物等均有较强的抵抗力。但是,Boray(1954)观察到10%,5%及1%的次氯酸钠溶液能迅速杀灭细粒棘球绦虫虫卵(parnell,1965年引用)。Meymarian & schwabe(1962)及 Laws(1967)
