However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT, therefore physical origins of spontaneous oscillations in the gyro-TWT are analyzed and characterized.

The animal model of this method system have, the characteristics of the high fat, high leptin, high Ins, and match with the characteristic of clinical and the pathologic of simple obesity. This studies showed: The acupuncture can obviously reduce the vaule of intaking food and water of the fat rats, and lower the body weight and fat; The acupuncture can urge the diameter, area, physical volume of white fat cell contract, Brown fat tissue of fat rat group surroundings vascular containing large quantity of white fat cell, the acupuncture group was less. this showed: The acupuncture enhanced the white fat cell metabolism, and promotesed the white fat cell to convert to brown fat cell; The frequency of spontaneous electric of nerve cell of pvn of the fat rat is high, the acupuncture counld depress the spontaneous electric of nerve cell of pvn, This showed: the acupuncture can depress the appetite passing to adjust function of pvn nerve; The monoaminergic neurotransmitter of inside of the fat rat brain is disfunction, the acupuncture can rectify this disfunction, and adjust level of 5-HT, and affect appetite, and improve metabolism; The level of leptin and Ins of fat rat increased high, The level of it of acupuncture group decreased, compared with the fat group p.001, This showed: the fat rats have the defeat of leptin and Ins in the body, The acupuncture can lowering this defeat, The level of leptin and Ins of the fat rat in the brain is less than the normal group, The level of leptin of the acupuncture group is high than the fat group, This showed: the acupuncture can increase the transportation of leptin from blood to brain.

本方法所制肥胖大鼠模型具有高体重、高脂、高leptin和高Ins血症的特点，符合人类单纯性肥胖病的临床和病理特征；实验研究显示：针灸能明显减少肥胖大鼠的摄水、摄食量及降低其体重、体脂；针灸能促使白色脂肪细胞直径、面积、体积缩小，减少肥胖大鼠棕色脂肪组织血管周围白色脂肪细胞数量，显示：针灸增强了白色脂肪细胞的代谢，促进了白色脂肪细胞向棕色脂肪细胞的转化：肥胖大鼠PVN神经细胞自发放电频率增加，脑内单胺递质紊乱，针灸通过抑制PVN亢奋的自发放电，调整5-HT水平，达到影响食欲，改善代谢的作用；肥胖大鼠血中leptin及Ins水平增高，与正常组大鼠比有明显差异，提示大鼠体内存在leptin及Ins抵抗，针灸后肥胖大鼠随着体重体脂的下降，血中leptin、Ins水平降低，与肥胖组比均有显著性差异，而针灸后大鼠脑内leptin增加，与肥胖组比P.05，提示：针灸具有改善leptin、Ins抵抗及增加leptin脑内转运的作用。
