critical density meaning in English
临界密度
Examples
- If its density is equal to the critical density
最后若密度和临界值一样，便会得出一个 - If the mass density is larger than the critical density , then the universe will eventually stop its expansion and start to collapse
的数值，引力便足以使宇宙停止膨胀，并令它重新收缩，这称为 - If the density of matter and energy in the universe is less than the critical density , the space curvature will be negative
事实上，宇宙中暗物质和暗能量的多寡决定了宇宙的几何结构。假若宇宙中的物质和能量的总密度低于临界密度，它是一个空间曲率 - As an extension of the big bang theory , inflation theory predicts the universe density is rather close to the critical density . thus , the universe is flat
根据为改进大爆炸理论而发展出来的暴胀理论，宇宙密度必定接近于临界密度，所以宇宙应是平坦的。 - The reflected light spectrum from interaction of uv laser with solid plasma was measured to investigate the frequency shift due to doppler effect of expanding critical density
测量了紫外超短脉冲激光等离子体中的光谱频移，分析表明是有质动力和等离子体热压力共同作用的结果。
