An effective medium method is developed for the slightly compressible elastic media permeated with air-filled bubbles, according to the nonlinear oscillation of the bubble, which happens when compressional wave travels through the porous media.
      
We examine the problem of finding the generatrix shape of a body of revolution which travels at supersonic speed and has minimum wave drag.
      
The amplitude of both fast and slow waves increases when the wave travels upward and diminishes when the wave travels downward.
      
The nonlinearity of the wave (i.e., the parameter characterizing the deviation of the wave from sinusoidal form) diminishes in the case of fast magnetoacoustic waves when the wave travels upward and increases when the wave travels downward.
      
It is noted that the ignition begins at a point and there is subsequent transition of the complete surface of the catalyst to the high-temperature region by a combustion wave that travels along the catalyst.

Based on the relation that the light intensity I, obtained when a light travels and returns through modulation crystals having pokle's effect is a periodic function of distance D, this paper introduces the principle of measuring phase delay with variable light-path. Taking for example the variable light-path by using optical incremental circle as shift sensor, this paper discusses the design principel and derives a system of practical equations to evaluate measuring distance under the condition of setting...

Based on the relation that the light intensity I, obtained when a light travels and returns through modulation crystals having pokle's effect is a periodic function of distance D, this paper introduces the principle of measuring phase delay with variable light-path. Taking for example the variable light-path by using optical incremental circle as shift sensor, this paper discusses the design principel and derives a system of practical equations to evaluate measuring distance under the condition of setting up frequency with indirect decimal system and replacing measuring phase with measuring length. Also introduced are logical circuits for parforming mathematical calculation and linking up the five equations.

The discrepancies between the measured values and the calculated ones of LF propagation delay have been analysed by Mr.shigetake Hjima(Japan) on the corrections of the receiver and transmitter co- ordinates and on the antenna delay of receiver.In this paper we tried to discuss this problem from the timing control of emission and the de- lay of the receiver.The data is from the results of three times of clock travel experiments which were carried out by Shaanxi Astronomical Observatory in China from 1978 to 1981,the results of the time compari- sion experiment between France and China via satellite symphony from June 18 to June 27 1979,and the data of clock travel experiment publis- hed by Mr.shigetaka Hjima in 《Time and Frequency in Japan》.The co- incidance (diviation≤1μs) and the discrepancies (diviation>2μs) bet- ween the measured value of LF propagation delay and the calculated nes had been analysed based on those experiments.The discrepancies are considered as the effect of the leading of the current's phase of trans- mitter antenna to the phase of the matter clock sigaals,we have also analysed the measured value of LF timing receiver and the adopted va- lue as well as their influence on the precisions of the timing control at transmitting station and the precision of the synchronization by me- ans of the LF time signals.The significance of measuring the time de- lay of the LF timing receiver are emphasized lastly.

关于 LF 电磁波传播时延实测值与计算值不一致性的问题,日本 Shigetaka Hjima 先生从收、发两地坐标改正和分析 LF 定时接收机天线时延的角度作过论述,本文试图从授时控制 LF 定时及接收机设备时延两个方面进行探讨。根据1978~1981年三次搬钟实验结果,上海天文台、陕西天文台利用“交响乐”卫星和巴黎天文台进行时间比对的结果(1979年6月18日~27日)以及 Shigetaka Hjima 先生在《日本的时间与频率》一文中所公布的搬钟实验资料。分析这几次实验所反映的 LF 地波传播时延实测值与理论计算值的一致性(偏差小于1μs)与不一致性(偏差大于1μs)的情况和其中的原因,认为这种不一致性的主要原因是由于 LF 时号的发射天线电流相位超前于主钟秒詹号。本文讨论了 LF 定时接收机时延采用值和实测值问题,及其对授时台控制和时间同步准确度的影响.强调了正确测定 LF 定时接收机系统时延值的重要性。

A simula ted test of travel via MX1502 satellite surveyor is presen- ted in this paper.The results of the test have been tested will TV co- mparison method and show that the accuracy of synchronization is of the o der o microsecong for short distances(~30km).Besides,the resulte of date processing show that the square root error of the data is 50 ns.

本文介绍了利用 MX1502卫星测量仪进行模拟搬钟试验。试验结果表明:在短距离内(30km 左右),通过电视比对进行检验,其同步精度为微秒量级,数据经过处理,中误差为50ns 量级
