light mass

基本解释

The sphere, for instance, represents how space is bent around a star or other mass - light passing through this warped space bends in an effect called gravitational lensing.
作为例子，这个球面代表了恒星或其他质量附近的空间是怎样弯曲的 - 光通过这个扭曲空间所引起的弯曲称为引力透镜效应。
Comparing the calculated mass and the total mass of the light-emitting galaxies in the galaxy cluster would determine the amount of dark matter that exists in the galaxy cluster.
把计算出的质量和星系团中发光星系的总质量相比较，就能确定出星系团中存在多少暗物质。
The viscosity reducing rate will reach over 99% or more when augmenting light oil mass of water-free heavy oil well, lower temperature will lead to better performance of viscosity decrease.
不含水稠油井的降粘率随掺稀质量的提高而增大，其值可达99%以上，温度越低降粘效果越好。

Tony Tyson and David Wittman, who work at Lucent Technologies' Bell Laboratories, in New Jersey, and their collaborators have proposed building a telescope that estimates the distribution of mass in the past by analysing these deflected light-waves, a technique known as three-dimensional mass tomography.

In an article entitled "Missile Defense at Last" ( see attached), Mr. Krauthammer calls attention to the absurdity of the present situation -- in which even the Clinton Administration acknowledges the need for deployment of anti-missile defenses in light of the burgeoning proliferation of missile-borne weapons of mass destruction, yet it proposes to afford the Russians a veto over any such deployment.
