超距作用

试论超距作用

Exposition about action at a distance

信息能瞬时通过宇宙传播的这个思想被称为超距作用。

The idea that information can travel across the universe instantaneously is called action at a distance .

此外，它还具有超距作用和反转录活性。

In addition , it possesses " action-at-a-distance " and reverse transcriptase activity .

牛顿的重力理论假设了超距作用，明显违反了相对论原理。

Newtonian gravity assumes action at a distance , in clear violation of the principle of relativity .

但是不存在后来牛顿的万有引力说里讲的那种超距作用。

But there is no action at a distance , as later in Newton 's theory of gravitation .

爱因斯坦和其他很多科学家都被超距作用所困扰，因为它意味着信息可以传播得比光还快。

Einstein and many other scientists were troubled by action at a distance because it means that some information can travel faster than light .

我们知道，牛顿的万有引力定律认为，一切有质量的物体均相互吸引，这是一种静态的超距作用。

We know that Newton 's law of gravity that all objects have the quality of both the mutual attraction , which is a static role of ultra-distance .

磁力研磨加工是利用辅助磁场对自由松散的磁性磨料的超距作用，导入磁场和电场来实现工件表面精密研磨的加工方法。

It is a finishing method which utilizing the action at a distance between magnetic pole and incompact magnetic abrasive to finish work piece by introducing the magnetic and electric fields .

本文概述了超距作用概念的历史发展，讨论了超距作用和近距作用概念之间的争论。

This paper discusses the historical development of the concept of action at a distance , and the issue between the idea of action at a distance and action through the medium .

信息能瞬时通过宇宙传播的这个思想被称为超距作用。功不是在某一瞬时或某一点定义的，而是在一段距离上定义的。

The idea that information can travel across the universe instantaneously is called action at a distance . Work is defined not at an instant or at a point but over an interval .

这种物理现象意味着，相隔甚远的物体之间可以相互影响，曾被爱因斯坦称为“鬼魅般的超距作用”。他否认了这种可能性，拒绝相信无论离得有多远的物体之间都可能相互影响。

Einstein referred to this physical phenomenon , which suggests that objects separated by great distances can affect one another , as " spooky action at a distance . " He rejected the possibility , refusing to believe that objects could influence each other no matter how far apart they were .

如果把负群速度看成是某种能量的传播，那么超光速出现在负群速度开始时的瞬间，因而它是超距作用，违反能量守恒或动量守恒。

If the negative velocity were regarded as that of some energy , superluminal propagation would occur at the beginning instant of the negative group velocity propagation so that it is an action at distance which would violate causality and energy ( or energy flow ) conservation laws .
