vertex power

基本解释

This paper describes the error in focimeters, the principle of selection on curvature of inside face for vertex power of standard lenses and the method for measuring them.
本文敘述了焦度計的誤差，頂焦度標準鏡片內表麪彎度的選擇原則，以及標準鏡片的測量方法等。
A common property of many large networks is that the vertex degrees follow a scale-free power-law distribution, The BA model features two generic mechanisms: the networks expanding and the pref.
實際網絡中節點分佈的一個廣泛特征是度的無標度冪率分佈，BA模型認爲形成這種特征的兩個主要因素是網絡增長和節點間的偏好連接。
It is found that different types of real-world networks the vertex vanishment follows a strong degree preference, the vanishment rate of degrees also follows a scale-free power-law distribution.
通過對不同類型的實際網絡中節點消退情況的統計分析發現，實際網絡中節點的消退有很強的度偏好，不同度的節點的消退率同樣具有冪率分佈特征。
