For the requirement of instantaneity, an implicit real-time discretisation is used, and the equations are integrated in a fictitiously pseudo time. This approach allows the real-time step to have two-order accuracy and accelerates the speed of convergence. Based on the theory of Mr. John K. Dukowicz and the algorithm of Mr.

在非定常计算中，本文同时采用当地和虚拟时间步，即双时间推进，在每个真实时间步上采用虚拟时间进行定常迭代，从而不但使时间迭代具有二阶精度，并使计算时间大大缩短，这样程序与定常程序在算法思想上一脉相承。

Bolt body has several spiral grooves on its outside surface which collect the dust and fouling from inside the receiver, and thus greatly improve reliability of the gun under field conditions.

螺栓机构已在其外部的表面，收集来自接收器内的尘埃和污垢数螺旋槽，从而大大提高野战条件下的枪的可靠性。

The mathematical programming formulation and related solution procedure are established by the traditional BEM. Through the discretization of space and time, the elastoplastic stress simulation method and reduce-basis technique are adopted to construct the self-equilibrium stress field. The numbers of variables and constraint equations in the resulting mathematical programming formulation are reduced greatly and then the dimension obstacle of computation in 3-D limit and shakedown analysis is overcome.

On the aspect of error compensation, the system using the geometric average sound pressure instead of the arithmetic average sound pressure to get the sound pressure of the measurement point. This method not only reduces the high frequency error in the sound intensity measurement, which compensates the finite difference approximation error, but also greatly reduces the computation of the sound pressure spectrum.

误差补偿方面，课题采用几何平均声压代替通常的算术平均声压来计算双传声器法的声场声压值，这样不仅可以有效的减少声强测量中的高频误差，对有限差分误差起到了补偿作用，而且还大大减小了声压谱计算中的计算量。
