On the basis of shock wave characteristic of the supersonic projectile and the detailed analysis of measured datas,a method of decomposing and reconstructing the trajectory shock wave signal and muzzle blast wave signal is proposed and the characteristic parameters for positioning sound source and calculating trajectory vector with regular tetrahedron detection array are extracted.

根据空气动力学原理，在阐述超音速弹丸的弹道波特性的基础上，通过详细分析实测的声信号，提出了弹道波信号和枪口冲击波信号的小波分解和重构方法，提取了利用正四面体探测基阵进行声源定位和弹道矢量计算的特征参数，获得了满意的实验结果。

High precision format, unstructured dynamic mesh with a large displacement and multi-species gas flows were computationally expensive, the problem of resourceless and inefficient of single computer appeared. Parallel arithmetic based on PC-Cluster system for the oblique detonation wave flow and the muzzle flow include high speed projectile were discussed. The results proved that the rationality of parallel arithmetic provided a new method to simulate the complex chemical reaction flows. The present code represents a validated, efficient and versatile tool developed for the simulation of hypersonic multi-species chemical non-equilibrium flows.

高精度计算格式、化学反应源项的刚性和大位移的运动边界处理都给计算和存储带来了沉重的负担，单机资源不足和计算时间长的问题凸现，利用PC机和局域网资源建立分布存储式并行计算系统，并基于非结构动网格和分区算法开发了复杂化学反应流场数值模拟的并行计算程序，对高速飞行实验弹丸诱导的斜爆轰波流场和含有大位移动边界的膛口燃气射流场进行了并行模拟，有效地缩短了计算时间，扩展了计算规模，为复杂化学反应流数值模拟研究提供了新的手段。

Once George had gone out to the kitchen and made a ham-and-egg sandwich "to go" that a man wanted to take with him. Inside the kitchen he saw Al, his derby hat tipped back, sitting on a stool beside the wicket with the muzzle of a sawed-off shotgun resting on the ledge.
