Clinical Detection and Feature Analysis on Neuro Signals

Research on neuro signals is challenging and significative in modern natural science. By clinical experiment, signals from three main nerves (median nerve, radial nerve and ulnar nerve) are successfully detected and recorded without any infection. Further analysis on their features under different movements, their mechanics and correlations in dominating actions are also performed. The original discovery and first-hand materials make it possible for developing practical neuro-prosthesis.

饮用水消毒剂的特点及杀菌技术的研究

阐述了几种消毒方式的特性及其应用前景,通过对比臭氧,ClO2,微波,KMnO4及紫外线的消毒效果,确定了取代液氯消毒饮水的最佳方案.影响消毒剂效果的主要因素有温度、pH值及作用时间.消毒剂浓度与作用时间的关系可用ct(mg*min/L)值来表示,代表消毒剂的杀菌能力,对大肠杆菌,当pH为6～7时,臭氧、ClO2、氯的ct值分别为0.02,0.40～0.75,0.034～0.050.升高温度会加强消毒剂的灭菌效果,要保持原来的消毒效果就需要延长作用时间或增大消毒剂的剂量.     

Radiosensitivity of β-elemene on rabbit VX2 renal transplant carcinoma model

Objective To investigate the effects of low dosage ofβ-elemene on the radiosensitivity of rabbit VX2 renal transplant carcinoma model. Methods We took the rabbit VX2 renal transplant carcinoma as the model. Experimental rabbits were divided into three groups： the control group, the radiation group, and the radiation ＋β-elemene （radiosensitivity） group. The change of tumor was observed by Spiral CT and B ultrasound to compare its regrowth period. The tumor was measured by light microscopy and electron microscopy. Results The tumor in radiosensitivity group was restrained obviously and the sensitization enhancement ratio （SER） of β-elemene was 1.89. Different apoptosis was observed under transmission electron microscopy. Conclusion Low dosage β-elemene can enhance the radiosensitivity of rabbit VX2 renal transplant carcinoma model and induce the apoptosis of tumor cells, but the mechanism needs further study. It promotes apoptosis in mechanisms in vitro.

焊接残余应力对环肋圆柱壳水下声辐射影响研究

文章重点研究了焊接残余应力对环肋圆柱壳水下声辐射的影响。通过运用热弹塑性有限元法数值模拟环肋圆柱壳对接焊接过程,得到厚板环形焊缝的三维残余应力场和应变场,然后对含有残余应力的环肋圆柱壳动力特性进行研究,并运用有限元法和边界元法分析了低频激励下其水下声辐射的特点。研究结果表明焊接残余应力对环肋圆柱壳声辐射有较明显的影响,不仅使声辐射功率曲线和外场声压曲线向低频移动,而且使在大部分激励频率上含有焊接残余应力结构的声辐射功率和外场声压均大于无焊接残余应力结构。
