For the accuracy and complexity of different complexity analysis method are different, firstly, the ultimate strength of pressure hull is mathematically analyzed and calculated by ANSYS, and then the empirical formulation is modified according to the modified factors, which are gotten by the accurate model of ANSYS. So that the calculation accuracy will be improved and the calculation time will be reduced after the analysis model of pressure hull structure is integrated.

In this paper, we use FEM software ANSYS to simulate. Using FEM to evaluate the strength of pressure hull, the FEM model of outer covering and stiffeners can use shell element to establish, but it may waste much computing time to calculate. Therefore, in this paper, we can evaluate more easier by making use of the idea of effective-width, and considering the stiffener/plating combined moment of inertia.
本文采用有限元素分析软体ANSYS进行求解,在有限元素分析的模拟上,外壳与环肋均可用壳元素建立一实体模型来分析,但是在模型的建立上过於复杂,在解析上也需要更多的时间来计算,因此本文采用有效幅度的观念,考虑环肋与壳板间之组合惯性矩,将环肋部分取梁元素来模拟,如此一来可简化建立模型的困难度,且大大的缩短分析的时间。

From thermal analysis, weight loss occurs pronouncedly at temperatures above 300 oC in air and the residual weight increases with the reaction temperature. The particle size decreases with the increasing ethanol concentration., while the BET surface area decreases when the concentration of water is increased. Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.

A virus strain was isolated from the arthrosis of broiler chickens.The virus was shown to have spherical particles with isometric symmetry,no envelope,double deck capsids,with outer capsid of 75nm,inner one of 50nm in diameter by electron microscopy.The virus was not sensitive to aether,acid and heat.The virus could multiply on the chick embryo fibroblastcell,and could cause syncytial pathologic change with the appearance of cytoplasm inclusion bodies.The challenged chickens of one-day old by nasal,oral,intramuscular and pulvillus injection displayed obvious clinical symptom of severe arthritis and accompanied with pathological changes of malabsorption and necrosis.Meanwhile,four avian reovirus isolates CL,S1133,YH and YB were examined in the cross-neutralization test.
