查询词典 inversion point

First, basing on point halving, this thesis proposed a new efficient algorithm of computing kP lQ on an elliptic curve over the finite field with characteristic 2 and analyzed the computational efficiency. When the ratio I/M of inversion to multiplication cost is small, this new algorithm is about 5%～30% faster than the traditional algorithms.

In view of crosswell and 3D VSP layout, we use high resolution Radon transform based on Cauchy distribution to perform Radon transform for hole data. In this process, we study discrete dip overlay operator, improve damping factor that affects Radon energy convergence in order to let Radon energy converge, 6 resolve leggy in Radon data, and decouple smoothing effect among each energy group, we use Cauchy distribution to regularize data, let energy focus on one point, and improve Radon resolution. All these work well in wavefield separation. Finally, by inversion results and model trial, we verify the feasibility and stability of this method.

在Radon变换原理分析基础上，采用基于柯西分布的高分辨率线性Radon变换对井孔数据进行Radon变换，其间通过对离散倾角叠加算子求取的研究，及对影响Radon能量收敛的重要参数阻尼因子算法的改进，使数据在Radon域以能量团的形式呈现，得到很好的收敛效果，基本解决了Radon域数据的一定程度的拖尾现象，消除了各能量团之间的平滑效应，采用柯西分布来规则化数据，提高了Radon域的分辨率，Radon域能量也收敛到一个点上，有利于上下行波或纵横波波场分离。

Economy determines ethic only in the final analysis and if we make economy as the ethical starting-point it will inevitably get rid of the humanity nature of ethics and make the subject free of moral responsibility and bring about economical conciliarism. Although convention has same origins as ethics in etymon, content and function, it's difficult for it to qualify as the ethical starting-point for it lacks the spiritual essence that ethics has. Religious love-knot of ethics is just an artificial ultimate hypothesis of the rationality of value, but the religion's nature of inversion of man and God make it unable to be the ethical starting-point.

经济只是在"归根结底"的意义上"决定"伦理，若把经济作为伦理始点必将抹煞伦理的人文本性，消解主体的道德责任，导致经济至上主义；习俗尽管在词源、内容、功能上与伦理有诸多渊源，但由于习俗缺乏伦理的精神内涵而难以成为伦理始点；伦理的宗教情结不过是对价值合理性的虚拟的终极设定，宗教人神倒置的本质决定它无法成为伦理始点。
