    To obtain the tomograph of body tissues by ultrasonic echoes and then to improve the quality of images by digital processing method is one of the important techniques of medical diagnosis. The digital processing methods of ultrasonic medical images are reviewed in this paper. (a), Digital filtering technique. The accumulative average, low-pass, high-pass, notch filtering and band-pass of the medical ultrasonic informations may be realized by linear digital filters. The real time processing can be realized by using the Discrete Fourier Transformation (DFT) and the Fast Fourier Transformation(FFT). The distortion of the ultrasonic informations produced by the filtering effect of the body tissues may be corrected by inverse filtering or deconvolution. Algorithm with "template" is a convenient and flexible method. In addition, non-linear filtering technique such as homomorphic filters may also be used to improve the quality of the images. (b), Image enhancement technique. Histogram equalization, non-linear stretching, interpolation, pseudo-coloring methods etc. may be used for image-enhancement. In addition, it is possible to raise the diagnostic precision by using the edge detection and contour tracing methods. (c), Ultrasonic Computerized-Tomograph (UCT). This is a new ultrasonic image processing method. While still in the laboratory stage, it calls for close attention.

    利用超声回波作人体组织的断层显象并用数字处理方法提高成象质量是诊断医学的重要技术之一。本文综述了超声图象的数字处理方法。(一)数字滤波技术。采用线性数字滤波器可以实现对超声图象信息的累加平均、低通、高通、陷波和精通。采用离散宫氏变换(DFT)及快速富氏变换(FFT)可进行实时处理。应用反滤波或反卷积可以使超声信息受人体组织作用产生的畸变得到校正。采用模板运算是一种方便、灵活的方法。此外,还可以采用如同形态滤波器等非线性滤波技术来改善图象质量。(二)图象增强技术。可以采用直方图均衡、非线性伸展、内插补技术、伪着色等方法以增强图象。此外还可以采用边沿测量及轮廓追述的方法来提高确诊率。(三)应用计算机的超声断层显象。这是一种新的超声图象处理方法,尚在实验室研究阶段,但值得重视。

    First of all, this paper described composition modes of a Kalman filter in inertial navigation systems.Accorting to physical realizability of control, state variabls are divided, and by utilizing closed-loop feedback and open-loop compensation methods, Kalman filtering formulas with the hybrid structure are derived, such that the errors of the state estimation equals to optimal estimation crrors, whereby performance specifications of system are optimal. Previous derivation is applicable for navigation systems, and has phsical significance for many control systems.Furthermore, the statistical characteristics of the errors of primary components are discussed. Finally, by utilizing this Kalman filtering technique, a visualized realized program for statistical optimization in inertial navigation systems with selfcourse base is given.

    本文首先论述了卡尔曼滤波器在惯性导航系统中的构成方式。根据物理上实现控制的可能性,对导航系统的状态变量进行了划分,利用闭环反馈及开环补偿方法,推导出一种具有混合结构的卡尔曼滤波公式,使状态的估计误差等于最优估计误差,从而使系统的性能是最优的。上述推导不仅对导航系统是适用的,对很多控制系统亦具有实际意义。此外,还讨论了在惯性导航系统中主要元件误差的统计特性。最后,应用这种卡尔曼滤波技术,给出了具有自身航向基准的惯性导航系统统计最优化的一个具体实施方案。作者对中国科学院数学研究所关肇直教授及王恩平同志的帮助表示感谢。

    In order to study the structure of the crust and the upper mantle in the Xizang plateau, we have developed a set of analog magnetic tape recording system. Each seismograph consists of three 2Hz seismometers of type LS-1, three amplifiers of type DDF-5, three modulators and one magnetic tape recorder of type DCJ-1, a quartz clock, a timing circuit and a radio.The frequency band of the seismograph is 2Hz to 20Hz. Time error is less than 0.1 second. Being improved by the flutter compensation and filtering techniques, the S/N radio of the system is about 50 db. The amplitude error of the system is less than 10%.The field operation and the data analysis proved that this instrument could meet the needs for deep explosion seismic sounding. The analog tape can be converted to digital magnetic tape by using an A/D converter, and then data processing can be done on computer.
