A POLYNOMIAL CORRECTION TECHNIQUE USING RhKα COMPTON PEAK IN X-RAY FLUORESCENCE SPECTROMETRY

Compton scattering radiation of an X ray tube target line is widely used for matrix absorption correction in X-ray fluorescence analysis of heavy trace elements in light matrix samples,Compton scatter ing internal standard technique has been a routine method in geological samples since Reynolds recommended the method in 1963.     

船舶领域理论：发展现状及其MASS时代机遇

船舶领域理论近10年来得到了长足的发展，广泛应用于船舶避碰、航行安全决策和海上交通工程等领域的研究。随着MASS(Maritime Autonomous Surface Ships)概念和相关法规的提出，船舶智能化、自主化的进程将会加快，而船舶领域理论也将在这一趋势下朝着新的方向发展。综述了当前船舶领域的发展现状，包括现有的定义和建模方法，并讨论了船舶领域模型的实际应用场景；总结了MASS发展现状及其在未来革新过程中可能面临的挑战；针对MASS时代的需求，提出了未来船舶领域理论的发展和应用方向。

AN ANALYSIS OF DYNAMIC PERFORMANCE OF BACK REST OF WEAVING MACHINERG

Periodic variations of warp tension during a weaving cycle results in corresponding variationsof back rest position.However,the oscillation of back rest,in turn,shows effect on the variation ofdynamic warp tension.As a force transfer medium,warp yarn,with specific dynamic performances,is certainly one of the factors influencing the movement of back rest.In this paper,warp yarn istreated as a viscoelastic medium in studying the dynamic behaviours of back rest.A mathematicalmodel of a back rest system is developed based on the automatic control theory.Several factors arelisted,which show influences on the performances of the back rest system.Analytical work is car-ried out to identify the effects on the frequency response of the back rest systen resulting from vari-ations of such parameters as the modulus of elasticity,of both fast-elastic and slow-elasticdeformations,and viscosity coefficient.

80001 The Maximum Wave Force on Piers Qiu DahongIn this paper, the probability distribution of the maximum values ofirregular wave force on piers is discussed. Methods to estimate the ultimate maximum wave force under the action of a certain sea condition for a certaintime duration t and the maximum wave force of a certain cumulative probabi-lity are given here.In this discussion, we suppose that: 1) the Morison's equation is validhere; 2 ) the distribution of the water surface elevation un…
