The results showed an increased mean jitter value, fiber density and abnormal percentage both in EDC and AT muscles in group 1 and II diabetic patients comparing to the normal controls. These findings suggest an impaired or immatured neuromuscular junctions and an evidence of reinnervation through axonal sprouting in the diabetic patients either with or without nerve conduction abnormalities. In conclusion, the changes of axonal degeneration and reinnervation are the main pathophysiological mechanism of diabetic neuropathy, and the SFEMG is more sensitive than routine nerve conduction study in the diagnosis of diabetic neuropathyKeyword Axonal degeneration , diabetes mellitus , neuropathy , single fiber electromyography

结果显示两组糖尿病病患的连续间值差异，肌纤维密度及不正常比率比对照组显著增加(t试验，依序p.01)，在第一组糖尿病患中，伸指总肌的连续波间值差异比第二组高(p.05)，而连续波间值差异与纤维密度之间也成线性相关的增加(伸指总肌，r=0.471，p.01；胫前肌，r=0.386，p.02)，在伸指总肌测得的连续波间值差异上，第一组糖尿病患有75%不正常，第二组有33.3%不正常，而在胫前肌的连续波间值差异上，第一组糖尿病患有83.3%的不正常，第二组有75%不正常，在肌纤维密度的测定中，第一组糖尿病患的伸指总肌有27.8%不正常，胫前肌有58.3%不正常，第二组病患的伸指总肌有25%不正常，胫前肌有41.7%不正常，此结果表示糖尿病神经变造成的神经肌像交接处不稳定及有神经轴再生的重分布现象，因此也证实糖尿病神经病变的主要病理机转为神经的退化所致，而在诊断上单纤维肌电图检查的敏感度也比运动神经传导速度检查为高。

Methods Seventy-eight adult female PVGrats were divided into experimental group (n=60) and control group (n=18), intraneural injection technique was used to supply three kinds of NO donors with different half-life(DETA NONOate, DPTANONOate and Spermine NONOate) or saline into the rat sciatic nerve subperineurally under light microscope. At the 1th,2th,3th,7th,and 14th day of duration after sciatic nerve injection, a segment of injected sciatic nerve was taken out and embedded it in TAAB resin after tissue processing. Then it was cut into thin layers (1μm) and the histological changes were observed under high power microscope, meantime the number of degenerated axons were counted.

摘 要：利用Instron1342型电液伺服材料试验机，采用单轴压缩试验和双扭常位移松弛试验对大理岩、上盘二辉橄榄岩、下盘二辉橄榄岩、矿石、混合岩5组岩石的试件进行力学参数测试，获得相应的抗压强度、Ⅰ型断裂韧度等试验数据。

It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.

利用ASAP软件模拟每个透射面作为部分透射、部分反射的表面，对变焦光学系统非轴上光进行分析，模拟出变焦系统的光学元件表面和光机内壁，实行实际光线追迹，然后以像面为研究对象，进一步实施实际光线追迹，模拟出全部散射光在像面上的能量分布，找出鬼像形成的原因，并在此基础上通过改变二次反射所在面的曲率或改变所在面的折射率两种方法对变焦光学系统进行优化，减小鬼点数目，以提高系统的成像质量。
