| | An experiment of digital processing for seismic surface wave dispersion has been, carried out on the machine model 108-B. It consists of: (1) numerical filtering of both constant and variable parameters; (2) techniques of measuring group velocities by using "moving window" and "multiple filtering"; (3) cross-correlation method of measuring phase velocities. Fast Fourier transform has been applied for computing the cross-correlation of seismic surface waves for records at two stations. Beside the benefits of... | | 在108-乙型数字计算机上进行了地震面波频散处理方法的试验。包括:(1)参数固定的和可变的数值滤波;(2)测定群速度的“移动窗”和“多重滤波”技术;(3)测定相速度的互相关法。应用了快速傅氏变换计算两个台记录的地震面波的互相关函数。使用数字处理技术分析地震面波频散,除了提高计算速度和便于处理之外,还可扩大测量周期的范围至20—70秒,从此可作出对地壳参数性质的更可靠的测定。 | | 文摘来源 | | Transport of the sediment of Huanghe River into the sea and distribution of surface Suspended Sediment in the Bohai Bay have been studied, by using computer image Processing, and the observed sediment data. We came to the following conclusions that:1.Most of the sediment emptied into the sea from Huanghe river is settled down near the estuary, only a small amount of it is transported toward the sea.2.There is a clear water circulation near the 119°03′E, 38°N, it stops the suspended Sediment transporting tow... | | 本文利用计算机图象处理技术、NOAA卫星影象资料和实测泥沙含量资料,对黄河入海泥沙的扩散特征和渤海湾表层悬沙分布情况进行了分析,经研究后发现: 1.黄河入海的大部分泥沙沉积在口门附近,只有一小部分向外海运移,扩散。 2.在119°03′E,38°N处经常存在一个清水环流,它起着阻挡黄河泥沙北移的作用。 3.渤海湾表层悬沙的分布,夏季与冬季有明显差别,特别是在黄河口附近海域,冬季由于风浪造成的浅滩掀沙,泥沙等值线与等深线基本一致;夏季则在5号桩附近的外海清水紧靠岸边,阻挡黄河泥沙北移。 | | 文摘来源 | | In this paper a new physical modelling technique of tidal current is presented in which discharge regulators automatically control discharge on three boundaries, while the boundary discharge is determined by mathematical model of tidal current. The rotation characterisics of tidal current in estuarine water area is successfully reproduced in the model. By using hydrogen gas bubble trace lines combined with real time image capture technique, the difficulty of measuring low velocity and variable current direc... | | 本文以灌河口外航道整治物理模型试验为依据,介绍在国内率先运用由数学模型提供边界流量条件后,通过物理模型三面开边界实行全自动控制边界流量,成功地复演了河口口外水域旋转流流场特性的一种新型试验方法.模型中应用氢气泡示踪线结合计算机视频图像处理技术,较好地解决了口外开敞式水域流场低速、流向瞬变的测试难题,提高了量测精度. | | 文摘来源 | |   | | << 更多相关文摘 |
