Our previous studies demonstrated the ultrasound-induced skin optical clearing enhancement with topical application of optical clearing agents on in vitro porcine skin and in vivo human *** objective of this study was to investigate the possible mechanisms of the enhanced skin optical clearing by ultrasound *** clearing effects of ex vivo guinea pig abdomen skin topically applied with 60% glycerol or the combination of 60% glycerol and ultrasound were studied by optical coherence tomography(OCT).Microstructure of skin surface was examined by scanning electron microscopy(SEM).Ultrasound with a frequency of 1MHz and a power of 0.75W over a 3-cm probe was simultaneously applied with glycerol solution for *** combination of 60% glycerol and ultrasound results in a 19% increase in OCT 1/e light penetration depth after 30min,which is much better than 60% glycerol *** images demonstrated that changes in skin microstructure due to the tight order of the lipid bilayers in the stratum corneum disrupted and the separation of keratinocytes by the application of ultrasound contribute to the ultrasound-enhanced intact skin optical clearing effects.

A reinterpretation of the well-known formula of the 'mass-velocity relation' is exactlyderived from a new viewpoint with new concepts, such as the finiteness of the transmitting velocityof force (TVF), effective action, and the coupled effect of the TVF for two EM fields, etc. Then, atrue meaning hidden in the Lorentz factor is exploited : i.e., when a charged particle is moving at aspeed v under an EM field, the effective action exerted on it by the field varies inversely with thespeed ratio β= v / U, where U is the TVF, which probably is equal to the propagation velocity ofEM field. The actual reduction of the effective action gives a false impression of mass ***, it is a major mistake in orientation to ascribe the (genuine) electrodynamics of movingbodies to any observation, or to any motion of an observer, while disregarding the facts of mutualaction.

关键词： Relativity Electrodynamics of moving bodies Mass-velocity relation, Lorentz factor Transmitting velocity of force, Effective action Coupled effect.

战火纷飞的抗美援朝战场,敌人对朝鲜北部京义线铁路运输咽喉“317”地段实施疯狂地“绞杀战”,我英勇的志愿军铁道兵战士为保障“铁血大动脉”的畅通,正在敌机狂轰滥炸的间隙,用自制的“超越打桩机”紧张地抢修线路。这个战地发明的高效器械吸引了来前线采访的战地记者,他打开随身的画夹,抽出速写本画了起来。“突然周围腾起烟尘,泥石飞溅,一串机关炮扫射,之后听见敌机俯冲拔高时炸雷似的巨响,我下意识地摸摸自己的头手脚都在,懵出一身冷汗,这时战友们来救我,人完好,只是画夹角被射穿”。
