The above-cited computer system has been used for a real-time simulation study of a destroyer exhaust steam and deareator pressure control system.

1引言 近年来，随着数字机特别是微机在工程上的普及，数一模混合仿真已为人们普遍采用，其优点不言而喻。

In A/D conversion, a part of shock signal especially peak value would be lost.

众所周知，在测量的数模转换过程中，必然伴随有一部分信号损失，尤其是峰值损失较大。

Firstly in this paper human mandibula was scanned by spiral CT. Then the data from CT was import into software (MIMICS 7.10) to reconstruct 3-D digital model. Software (Surfacer 10.5) was used to remove useless points , smooth the curves and output the STL file. The file was input into the rapid prototyping system, and was converted to slice format.

本研究首先用螺旋CT扫描离体人下颌骨，得到断层图像数据不经任何转换直接输入MIMICS软件进行三维重建，得到CAD三维数模，输入Surfacer软件除去杂点干扰，平滑曲面后，保存为STL文件，输入SLS快速成形系统通过激光烧结精铸蜡粉所制作的人下颌骨复制体，其形态、大小及结构与下颌骨实体标本基本一致。
