加热和充电的结合释放出电子, 电子通过真空管加速撞击到对面充满正电的电极上。
The combination of heat and charge releases electrons, which accelerate through the tube and strike a positively charged electrode at the other end.
加热和充电的结合释放出电子,电子通过真空管加速撞击到对面充满正电的电极上。
The combination of heat and charge releases electrons, which accelerate through the tube and strike a positively charged electrode at the other end. The rays are created by the energy of the impact.
这与早先认为的小行星的撞击实际上加速了结冰期的来临这一说法相矛盾。
This contradicts previous ideas which suggest the impact of the asteroid actually precipitated a period of glaciations, Gostin says.
所以在撞击的过程中,平均加速度,只有。
So therefore the average acceleration during the impact 5/ divided by one quarter...
在上世纪70年代,加速器能够增强速度,因此也能给粒子增强能量,但仅能使粒子撞击到一个固定目标上。
In the 1970s accelerators were capable of ramping up the speed and thus the energy of particles, but could only smash them into a stationary target.
宇宙射线撞击地球,携带着大量的高能粒子;其能量是现存最大加速器所产生能量的4千万倍以上。
Cosmic rays bombard the Earth from space and include particles of astounding energy, 40m times more powerful than anything that physicists can create in the world's biggest accelerators.
这些粒子一遇到地球的磁场,便会加速朝两极而去,并在飞行途中撞击大气分子。
When the particles meet with the earth's magnetic field, they accelerate toward the poles, crashing into air molecules as they go.
由于撞击夹刀块的能量包括爆炸气压和冲块的动能两项,所以夹刀块能获到很大的初始加速度。
Since the energy which strikes the tool holder includes the explosive gas pressure and the kinetic energy of the moving plunger, thus a high initial acceleration of the tool holder is obtained.
本文介绍了用测量大锤撞击作用下的力和加速度以确定桩的静态轴向承载力的凯司(case)法。
A method named CASE method is presented for determining the statical axial bearing capacity of piles from dynamic measurements of force and acceleration performed under the impact of a large hammer.
其中一个实例(在NHTSA 撞击测试己经测试)亦有加速表、迴转仪、和其他感应器测量废气、燃油里数…等资料。
One of the units (being tested for use in NHTSA crash studies) also has accelerometers, gyros, and other onboard sensors to measure emissions, fuel mileage, etc.
