频率63赫、强度122分贝的振动作用于家免的左后脚掌,发现大脑右顶部软膜的小动脉(特别是直径小于30微米的小动脉)痉挛,大多数痉挛保持的时间很长,有些以后转变为微血管扩张;随小动脉直径增大则痉挛减少。振动作用引起小静脉明显扩张。可见,局部振动作用下微循环床的改变可能
The frequency of 63 Hz, the intensity of 122 db of vibration on the role of home-free left hind paw and found the right top of the soft membrane of the right parietal artery (especially smaller than 30 microns in diameter arterioles) spasm, most of the spasm to maintain a long time, some After the change into microvascular dilatation; spasm decreases with the increase of arteriolar diameter. Vibration caused a significant expansion of small veins. Can be seen under the local vibration of the microcirculation bed changes may be
