(5) occasionally occur where the flow of particles greatly increases and the interplanetary magnetic field becomes much stronger. These substorms are frequently visible on the Earth because they increase the intensity of the polar lights. Recently, five identical probes were blasted into orbit in a...
The grinding fragment which possesses the size which is smaller than the cavity of the formation type which is used for those productions the precusor alumina grinding particle of formation closed die forging, at least majority of these precusor grinding particles by exposing to the drying ...
aThe compression stroke serves to break up the fuel into even smaller particles. This happens due to the sudden swirling and churning of the mixture as it is compressed. 破坏燃料的压缩冲程服务更小的颗粒。 当它是压缩的,这发生由于突然打旋和搅动混合物。[translate] ...
A high early strength pozzolan cement includes larger sized pozzolan particles and smaller sized hydraulic cement particles which contain tricalcium silicate (e.g., Portland cement). Particles larger than 10 μm are predominantly (50%, 65%, 75%, 85% or 9
A new study shows that Americans are consuming as many as 121,000 particles each year. Measuring 50 to 500 microns in length, microplastics come from a variety of sources, including large plastics that break down into smaller and smaller pieces. Therefore, much remains unknown...

“To study these nuclei, we can’t just find them naturally on Earth,” said Spyrou. “We have to make them. And that is the specialty of FRIB—to get stable isotopes that we can find, accelerate them, fragment them, and then produce these exotic isotopes, which might only live for ...
a In general, when the motion was discontinuous, as is the case in a repeated braking action, smaller wear particles are generated. 一般来说,当行动是不连续的,象案件在一次重覆的刹车的行动,更小的穿戴微粒引起。[translate] awilliams believes that as the generations move through the corporate world...
