临界

Experimental results indicate that there is a critical value of carbon fiber weight fraction which effects the electrical properties of SCF/NBR.When carbon fiber weight fraction comes to this critical value,volume specific electrical resistance and static ...

通过实验发现，碳纤维的含量对短碳纤维／丁腈橡胶（ShortCarbonFiber／NitrileButadieneRubber）电性能的影响，存在一个临界值，当碳纤维的含量达到此临界值时，SCF／NBR的体积比电阻和静电电压都得到显著的降低。

The article covers the full research on such aspects as mathematic description, numerical analysis method and their practical applications. The diphase heating surface is divided into a hot water section, a evaporation section and a micro overheat section , the problems of model switching are avoided successfully between subcritical and supercritical working condition in the model of The diphase heating surface, and the model can be used for between subcritical and supercritical working condition without causing the model stiff infinity prick up problem. The mathematical model and dynamic characteristic account is unified and predigested for the diphase heating surface of once—through boiler under subcritical and supercritical pressure, and propose that the working conditions at phase change point could be used as divide criterion between water region and steam region under supercritical pressure, the problems are solved successfully between water and steam phase change point under supercritical pressure.

Using the opened thermosiphon of 38x3 as experimental element and water as working fluid,the characteristics of dynamic low load boiling,stable severe boiling heat transfer coefficient and critical heat flux are gotten for the opened thermosiphon at the pressure of 0.02-0.1MPa and 0.1-0.8MPa respectively,which makes up the drawback that the opened thermisiphon has not yet accurate boiling heat transfer relationship formulas.

In contrast to the situation for a homogeneous isotropic neo-Hookean sphere, it is shown that not only there exists a secondary turning bifurcation point on the cavitated bifurcation solution which bifurcates locally to the left from trivial solution, and also the critical load is smaller than that for the material with no perturbations, as the parameters belong to some regions.
