After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.

在证明了理想滤波器的不可实现性之后，得知通过选择适当的窗函数可获得很好的滤波函数，经过两个实际滤波器的效果对比，我们选取了较好的"巴拿马帽"形滤波函数，同时也介绍了一个有效的提高重建质量的线性内插函数，概要地叙述了平行射束图象重建的计算机具体实现步骤后，对几个物体的模拟投影数据进行了重建：投影角为180°，每视角下有100个平行投影数据点，在386微机上重建尺寸为64×64，时间约为40秒；在486/33MHz微机上只用了12秒，图象的象点精度是0.31mm。

As the mine accidents happen frequently in recent years, the detecting technology for microseism becomes much more important. However, there is no advanced microseism detecting system at home. It's pretty important for microseisms denoising and Reversion. A wavelet denoising method is presented here to process microseism signal, and the microseism record can get high signal to noise ratio. Meanwhile based on the software of LabVIEW, s design of real-time detecting system for microseism based on virtual instrument is presented. The advantage of the virtual instrument was sufficiently exerted to achieve the real-time detecting and analyzing of the microseism.

以往基于DSP或其他单片机的微震系统，其资源的有限性很难达到理想的采集效果，同时也难以完成先进算法的实现，而对微震信号的去噪与还原在监测系统中起着很重要的作用；在深入分析小波变换的信号去噪方法基础上，对微震信号进行了处理，得到高信噪比的微震记录，实现了对噪声的有效抑止；同时在LabVIEW平台软件设计的基础上，实现了一种基于虚拟仪器微震实时检测的设计方案，充分发挥了虚拟仪器的优势，结果表明基于LabVIEW的微震系统能很好地完成实时监测及其分析。

A model of temperature field in surface layers during sliding was set up based on the law of heat conduction. And, a computer simulation for thermometric data which were real-time recorded by a thermal video system was carried out by using a mini-computer according to the model. There was an ideal fit between the measured data and the calculated curve.
