pencil of planes

In this parper, we correct a mistake in paper[1], and introduce a plane pencil equation of two parameters, and so overcome the limitation to solve problems by using the plane pencil in paper [1].

本文纠正了文[1]中一处错误求解,并介绍了含有两个参量的平面束方程,从而克服了文[1]利用平面束解题的局限性。

And combining with theory of plane pencil, the 8 CDF biotthogonal wavelet different from Cohen s paper are obtained.

应用文中提到的算法一,给出了Cohen文中原来三组CDF型小波中,每组内的小波顺次逐一提升的关系;再用算法一结合平面束理论得到与Cohen文中12个CDF型小波不同的8个小波;还给出了算法二,并讨论了寻求两个已知CDF型小波之间提升算子S(ω)的问题。

Its main ideas are as follows: (1) dividing the quartic implicit algebraic surface into several patches; (2) computing the intersection curves of each surface patch with a pencil of planes rotated successively along a certain fixed axis; (3) parametrizing the curves.

首先对四次代数曲面进行分片 ,然后对每一个分片曲面利用一组同轴平面束与其求交线 ,通过对求得交线的参数化来完成对整个分片曲面的参数化 。

On the base of the Westervelt equation, this paper studied the acoustic field of the second harmonic of a collimated beam of sound, in particular the directional characteristics.

以Westervelt方程为理论基础,推导了平面波束二次谐波的声压和声强分布,得出平面波束的二次谐波的指向特性主要与波束的尺寸和波长的相对比值、波束的频率有关,高频时也会有旁瓣出现,但在所有频率范围以内都有较尖锐的指向特性。

In a narrow plot,ground can be hypothesized a planar plane,so the planar constraint can be used to acquire planar points.
