鉆井泥漿被泵入鉆桿內部，從鉆頭的噴嘴流入環(huán)形空間www.13色哟哟。

The three patches of receptive field existed a few overlapping areas and also had separate area. When the intensity of mechanical stimulation was controlled to evoke only one T cell excited, the simultaneous intracellular recordings with four microelectrodes (one in AP cell and the other three in three T cells respectively) could shown that under natural conditions AP cells can positionally discriminate the area of the mechanical stimulation on a single annulus with the postsynaptic potential.

將機械刺激強度控制在只激活一個T細胞時，利用四根胞內微電極同時記錄（三根電極在三個T細胞內，第四根電極在AP細胞內）久操黄片，結果表明AP細胞在自然條件下對單個體環(huán)上的機械刺激區(qū)域確實具有突觸后電位的部位分辨功能。

Furthermore,the beam quality on far field is discussed.Temperature rise,thermal deformation,wavefront distortion and beam quality of fused quartz(SiO_2) window and white bijou(Al_2O_3) window irradiated by the annulus beam are simulated as examples.
