Abnormally accelerated particle in pseudospark discharging 贗火花放電產(chǎn)生的異常加速高能粒子
The most obvious application of the relativistic force of an ultraintense laser beam is to accelerate particles 超強雷射光束這種具相對論效應的力量,最明顯的應用當屬粒子的加速。
If we could accelerate particles far more quickly than is allowed by the electrical breakdown limit, the accelerator could be made more compact 如果我們可以比電場崩潰極限所允許的還更快加速粒子,加速器就可以做得更小。
Investigators concluded decades ago that the generation of a voltage driving a simple, single current could not heat the solar atmosphere quickly enough or produce a flux of accelerated particles that is sufficient to make a flare 研究人員數(shù)十年前的結(jié)論認為,單單由電壓驅(qū)動電流,無法很快加熱太陽大氣,或產(chǎn)生足以形成日焰的加速粒子流量。
Although light waves in the regime of classical optics can have electric fields as strong as those near bolts of lightning, these fields are not effective for accelerating particles on their own, because they oscillate transversely 在古典光學中,雖然光波的電場有可能大到如閃電雷擊的程度,但因為電場是以橫向振蕩的,所以無法有效用來加速粒子。
"sound " related therapies ultrasonotherapy uses 20, 000hz or high ultra sound to accelerate particles in cells and soften tissue, functioning like a " micro massage . " it can also have a heating effect at the interface of different tissues to accelerate the absorption process 超聲療法ultrasonotherapy使用頻率高于20,000赫茲的超聲波進行治療,使細胞內(nèi)的質(zhì)點獲得加速度而產(chǎn)生碰撞,造成對細胞之微細按摩作用,如此,不僅能軟化較硬的組織,且可在不同組織界面處起溫熱作用,而增進細胞膜的吸收過程。
