本文利用二维冰雹云模式,给出了相应的流场,设计了一个二维冰雹增长运行模式,分别对三种流型的冰雹增长运行轨迹作了模拟研究,结果表明:1.大雹的增长运行总是沿着相对水平风速零线旋转进入主上升气流区;轨迹距零线越近,冰雹长得越大;一旦远离零线,不是吹出云外,就是向下降落。2.冰雹的增长运行轨迹沿零线的上下旋转是形成冰雹多层结构的主要原因。3.形成大雹的雹胚起始出发点是位于主上升气流区外沿水平相对风速为零的区域内。

Canonical Katzenelson algorithm is presented by L.O.Chua in the references[1]. It's a well known algorithm for solving pieeewise-lincar resistive networks.In the iterative process,the solution curve from the starting point(x~(0) converges to a solution,but the starting point must be in the area where Jacobian matrix satisfies det J>0. In this paper,we present the criterion for solution curve from one area to another.We can select the starting point in any area also.When one solution is got,we can go on to get...

规范化Katzenelson算法是L.O.Chua在文献[1]中提出的,它是规范化分段线性化电阻网络著名的迭代算法。它需选Jacobain矩阵行列式大于零的区域的内点为初始值.迭代过程形成的解曲线,从初始值开始经过若干个区域终止于某个解点.本文推导出解曲线从一个区域进入邻域的完整的判别式,可选任何区域的内点为初始值,解曲线到达某个解点后可以继续前进,以寻找其它的解,故也适合于多解网络的求解。

f-k filtering for linear noise removal is one of usual methods for removing noisein seismic data processing. However, the ill use of f-k filtering will result in de-structive effect, namely, causing new linear noises in the seismic section whose o-riginal linear noise has been reduced. The reason why the new noises appear liesthat the oversuppression of original noises in f-k domain makes noise energy unbal-anced.

f-k filtering for linear noise removal is one of usual methods for removing noisein seismic data processing. However, the ill use of f-k filtering will result in de-structive effect, namely, causing new linear noises in the seismic section whose o-riginal linear noise has been reduced. The reason why the new noises appear liesthat the oversuppression of original noises in f-k domain makes noise energy unbal-anced. A high S/N ratio seismic section without linear noise and its f-k spectrumare taken as examples to show the difference between full suppression of noise ener-gy and partial suppression of noise energy. It can be easy seen that neither strongnoise belt nor zero noise belt occurs in the f-k spectrum of the former case. Accord-ingly, the conception of noise energy equilibrium is advanced to remove linear nois-es, receiving quite good effect.

用f-k滤波消除地震剖面的线性干扰,是地震资料处理最常用的去噪手段之一,如果应用不当则会产生负面效应,使去噪后的剖面产生新的线性干扰。究其原因,主要由于在f-k域内过分压制干扰能量,使干扰波能量之间不均衡所致。本文以一高信噪比无线性干扰的剖面和它的f-k谱为例,说明完全压制干扰能量与部分压制干扰能量的区别。从中不难发现,在前者的f-k谱上,既无明显的强干扰能量带,也无干扰为零的区域,据此提出“噪音能量均衡”的概念。应用平衡噪音能量的方法去除线性干扰,可获得较好的效果。
