查询词典 potential difference

This paper is composed of three chapters, which respectively discusses the following impulsive delay difference equations with discrete variables and continuous variables:In chapter 1, we investigate the oscillation and nonoscillation of equation and some sufficient conditions for oscillation and nonoscillation are obtained. Consequently we extend these results to the difference equations with several delays and with nonlinear impulsive perturbations and with variable delays respectively.

Tailored exercise programs and yoga have been shown to reduce pain and prevent relapses in patients with chronic LBP.186–190 In randomized,clinical trials, osteopathic manipulation has been shown to provide moderate relief for LBP patients,191,192although one study showed no difference between the benefits afforded by true and sham manipulation.193 Acupuncture has also been shown in randomized trials to provide significant benefit in patients with chronic LBP.194–196 However, similar to manipulation, one of the largest and most methodologically sound studies found no difference between true and sham acupuncture.197

简易体操和瑜伽被证实在LBP患者中能减轻疼痛防止复发。在随机对照临床研究中，整骨推拿显示可以轻度缓解LBP患者的症状，但是一项研究显示真正和假的推拿对比后结果之间无差别。在一项随机研究中，针灸似乎也可以缓解LBP的症状，但是像推拿一样，一项大样本，方法更科学的研究认为真正和假的针灸结果并无差别。

Results:① there was significant difference in all personality traits except stableness and shrewdness among the three groups,(p 05). compared to the standardization samples, military pentathlon athletes were more outgoing, more dominant, more happy go lucky, bolder, tenser, but less suspicious, less apprehensive, and less self sufficient.② there was significant difference in the personality traits of outgoingness, happy go lucky and self sufficiency among the three grades of athletes (p 05). but the international master athletes scores of the personality traits varied little.
