 A computor method for slit-height correction is described, in which the experimental X-ray small angle scattering curve is represented by aFourier series. The pressure gradient was assumed to be an arbitrary function of time mathematically describable by aFourier series.

The bottom friction plays an important role in the interaction between tidal constituents. To study the interaction of the constituents through the friction, the quadratic bottom friction term is expanded into a Fourier series form. Many useful results are obtained.Starting from the nonlinear momentum equations, we obtain the mechanical energy equation. The balance of the mechanical energy in the Bohai Sea is discussed with the mechanical energy equation. By using the above Fourier series, a method to calculate the average drag coefficient CD in a certain area is deduced from the mechanical energy equation. This method is applied to the Bohai Sea and an estimate of CD=0.0013 is obtained. 在潮波动力学中,底摩擦在潮波之间的相互作用中起着很大的作用。本文将与速度平方成正比的底摩擦项展成一个Fourier级数,并讨论了底摩擦引起的潮波之间的相互干扰。 由非线性动量方程,我们得到机械能方程。利用以上的 Fourier级数,本文由机械能方程给出一种求解某一区域上平均拖曳系数C_D的方法。将此方法应用于渤海,求得该海区的拖曳系数C_D=0.0013。 In the case of one dimension, Sato  has given a uiform estimate of the remainder of Fourier series, Sn(f)-f.It follows that a test for unif(?)rm convergence for some Sn(f) is obtained. In this paper, the uniform estimate is extended to the case of many dimensions. 在一维的情况下,Sato给出了一个Fourier余项S_n(f)-f的一致估计,从而可得出某些S_n(f)的一致收敛的相应的判别条件。本文把这种一致估计推广到多维情形。 For f∈L' (T),Let Sn(t) be n—th partial sum of the Fourier series of f.Let {R(n)} be an O—regularly varying sequence.It was proved in this paper that if f∈L'(T),1n_0,then ‖S_n(f)-f‖_(L'(T))=0(1)n→∞ if and only if (?)(n)lg|n|=0(1),|n|→∞.This is an extension of the result obtained in reference.It was also given the proof of stanojivi(?)'s necessary and sufficient condition of L'(T)-convergence of Fourier series for((?),p)-reqularly varying sequece.therefore a class of...
