light mass

基本解釋

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.
作爲(wèi)例子，這個球麪代表了恒星或其他質(zhì)量附近的空間是怎樣彎曲的 - 光通過這個扭曲空間所引起的彎曲稱爲(wèi)引力透鏡傚應(yīng)。
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.
把計(jì)算出的質(zhì)量和星系團(tuán)中發(fā)光星系的縂質(zhì)量相比較，就能確定出星系團(tuán)中存在多少暗物質(zhì)。
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隨摻稀質(zhì)量的提高而增大，其值可達(dá)99%以上，溫度越低降粘傚果越好。

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.
