When gas superficial velocity was about equal to liquid superficial velocity, the probability density function of liquid holdup had a twin-peaked, when liquid superficial velocity was constant, one of the peaks would fade out and disappear with the in crease of gas superficial velocity. Through using the characteristics, the relative size of gas and liquid superficial velocity can be set initially.
在段塞流动中,当气相折算速度和液相折算速度相差不大时,持液率概率密度函数呈双峰分布;当液相折算速度不变时,随着气相折算速度的增大,持液率概率密度函数第2峰值逐渐减小,直至消失而变为单峰分布;利用这一特征可初步确定段塞流动中气、液相流量相对大小。

The solitary wave can be generated considering Goring and Raichlen's movement of a paddle. The proposed original linear solution for the solitary wave generation is expressed in the hypergeometric function. Two disadvantages of the original solution with large trailing wave and skewed wave profile are found by comparing with the theory of solitary wave derived from Boussinesq's equation. The difference between the original linear solution and the solitary wave theory results from the nonlinearity and dispersion of generated waves in the flume.
本文并以弱非线性的孤立波造波问题做为解析之对象,由於孤立波造波板速度为一超越函数,造成解析上的困难;本文以 hypergeometric 函数推求常微分方程式之全解,并与理论波形解比较后,发现由於未考虑非线性及分散性过强等问题,使得线性暂态解较理论波形拉长与歪斜,可能无法有效描述孤立波造波问题,故针对线性之分散关系做出修正。

The caculation results of Pubugou high rockfill dam under the action of design earthquake travclling wave show: in few cases, the seismic response under travelling wave input is less than that under routine input; but in many cases, the former surpasses the latter, and the rate of increase of few components has doubled and redoubled; the strengthened areas of seismic response under the action of travclling wave are in the direction which travelling wave has gone; compared with acceleration and displacement, dynamic stress is even more sensitive to travelling wave input; compared with the direction along river, the effects of travelling wave in the direction cross river are even more intense.

And by applying the linear dispersion relation of wave, all the properties of wave refraction including wave rays, constant phase lines, phase function and crest lines etc., can be expressed in explicit functions. By introducing an orthogonal curvilinear coordinate along the wave ray and the constant phase line, and with an estimated scale factor, the refraction coefficients along any wave ray can then be determined. The present results are verified by ordinary wave ray theory and some previous numerical results.

The shoaling wave height is related to wave steepness. Comparing with wave theories the shoaling coefficient of small amplitude wave theory_ which is not related to wave steepness, disagrees with experimental reset. The experimental result has the trend with Stokes third order shoaling theory, but Stokes wave theory overestimates the shoaling coefficient .

The earliest change of ERG in birdshot chorioretinopathy was the prolongation of cone ERG implicit time. Followed by the decrease of dark-adapted b wave amplitude. The b wave amplitude of cone ERG decreased later. The duration of the disease correlates with the amplitude of b wave in the same patient. The a wave was the last affected and the decrease of the a wave amplitude was disproportionate compared to that of b wave, revealing a typical negative type ERG.
