  convection current
We also carried out drying experiments of bead packings saturated with ethanol, at four different velocities of the boundary convection current, and with bead size ranging from 4.5 to 100 μm.
      
A recent investigation of the isospin forbidden electromagnetic transition of40Ca indicated that the convection current calculated in the shell-model should be modified by an "effective charge" to reproduce the transverse form factor.
      
It is shown that the findings of the present experiment are consistent with the interpretation that nuclei are excited by the new M1 mode through the convection current part of the M1 operator.
      
It is shown how the convection current contribution may be evaluated within the restrictions of gauge invariance.
      
Joule heating in this depletion layer and the ensuing temperature gradient, as well as the concentration gradient, give rise to buoyant forces which may create a turbulent convection current.

Inspects the flow pattern of natural convection in a building interior space in which two faced walls are heated and cooled,and the Rayleigh number varies from 10~10 to 10~11 .There are two Vortexes have been found.It conflicts with most theoretic and numeral studies before.There must be some unknown parameters to be further studied.

对建筑物内自然对流气流形态进行了可视化研究。实验在一长方形房间内进行 ,相对的两个壁面分别加热和冷却 ,顶部和底部隔热 ,使Ra数达到 10 10 - 10 11范围 ,实验发现顶部和底部出现了两个旋涡。此现象与过去大多数理论研究和数值计算结果不同 ,其未知因素有待进一步研究。

Biochemical terror patterns in public large space buildings include firing to produce poisonous gas,exploding gas bomb to spread poisonous materials and artificial distributing poisonous materials directly.The analysis showed that the fire smoke diffusion is driven by the thermodynamic buoyancy,the smoke-layer obviously appears in the upside of the building,and the smoke-layer will descend slowly or be controlled by the natural ventilation or mechanical ventilation.Besides the peripheral partial region of the explosion point,for explosive gas bomb to spread poisonous materials,the diffusion of poison gas mainly attribute to the upward inducement effect of the produced hot airflow,as well as the concentration grads.Without considering the convective movement of the indoor airflow,the poison gas was produced by artificial distributing poisonous materials mainly driven by the concentration grads.For various terror attacks,the motion of poisonous gases is basically affected by the convection airflow.Therefore,appropriate ventilation method can reduce the concentration of poisonous gas,and control the diffusion and conveyance process of poisonous gas indoor.The further research on the ventilation ratio,airflow distribution and control method of ventilation system is necessary for certain ventilation system can be used for different terror attacks.

公共大空间建筑生化恐怖模式主要有制造火灾产生毒性气体、爆炸毒气弹分散毒性物质和人工直接布洒毒性物质。分析表明:火灾烟气受热浮力作用,在建筑物上部出现明显的烟气层,采用自然或机械排烟能有效地减缓或控制烟气层下降;爆炸分散毒性物质,除了爆炸点周边区域外,毒气扩散受热气流诱导,以及浓度差引起的运动;不考虑室内对流气流的影响,人工布洒毒性物质产生的毒性气体,其扩散主要是由浓度差引起的。不同类型恐怖袭击产生的毒性气体受室内对流气流的控制,合适的通风方式能够控制毒性气体的扩散和输运过程。但能否采用某一形式的通风系统兼备防范不同类型的恐怖袭击,需要对通风系统的通风量、气流组织和控制方式做更深入的研究。
