随机方向
Examples
- The normal stress acting in any random direction can be obtained in the following way .
作用于任意方向的正应力可按下列途径来求得。 - How about each time you hit the ball , it speeds up and goes in a random direction
每次你击球,它加快速度并向一个随机的方向移动怎么样? - Shoving large numbers of electrons around is imprecise ? some shoot out in random directions , wasting energy ? and it creates lots of collisions , which produce heat
把大量的邻近电子撞开,是很不精确的:有些电子会凌乱地弹开,而浪费能量;同时也会产生许多碰撞而发热。 - As explained by the following figure , gas in low pressure and low density will alter the light that passes through it . it is because the gas will absorb light at some particular wavelengths and re - radiate it in random directions . thus , after passing through the low pressure gas , the spectrum of the original white light will have dark lines , called
并不是所有光谱都是黑体辐射光谱,如下图所示,低压下的低密度气体会改变通过它们的光线,这是由于气体会吸收特定波长的光波并随机向不同方向把所吸收的光线辐射出来,结果光线在通过低压气体后,原本的光谱上会出现很多称为 - In the inner region of the sun , a photon can travel for only about 1 cm or less before absorbed by materials mainly electrons and nuclei and later on re - emitted in random directions as one or more photons . in this way , the number of photons increases and the energy of each resultant photon is decreased
光子走了不足一厘米后,便会被其他物质主要是电子和其他原子核吸收,这些物质会把吸收的能量以多颗光子的形式释放出来,这些随机向四方发射的光子会较原本的光子有更长的波长,亦即能量亦较低。
