Simulation and experimental results indicate that for the SPWM inverter based on instantaneous output voltage feedback control,the fundamental open circuit output voltage incr...

仿真和实验结果表明，对于采用瞬时输出电压反馈控制技术的SPWM逆变器，其输出电压在空载时随着死区时间的增加而增加，负载电流超过临界电流后其输出电压随死区时间增加而下降；其阻性负载时的外特性曲线是一条先下降后上升的曲线。

The soil cutting experiment indicates that the interior friction angle and the shear intensity of soil is reduced;and the maximum principal stress is decreased due to the vibration load;it induces the decrease of digging resistance.

从理论上研究了振动掘削岩土的减阻机理，土壤剪切试验结果表明，振动载荷能够使土壤的内摩擦角变小、抗剪强度下降、最大主应力值减小，从而导致挖掘阻力降低；对土壤在静态载荷和振动载荷作用下的失效过程进行了对比仿真实验研究，可知土壤在振动加载的条件下强度显著下降，并提前于相同条件的静态加载而破坏，同时跟踪X方向的载荷发现，振动掘削最大掘削阻力可降低50%。

Analysis and simulation results show that tail distribution is very different from Gaussian; the effects of passive intermodulation interference on communication systems are mainly in the region of low bit error rates.

分析和数值结果表明：互调产物的幅度一般来说随阶数的增加而下降；高阶互调产物的下降行为本质上与传递函数的类型有关。

The results showed that the rural residential land become fragmentized during the years 1995-2010. The indices of number of patches, area-weighted mean shape, mean fractal dimension of landscape structure in Suining county gradually increased. Interspersion and Juxtaposition index and Shannon's diversity index were decreased.

结果表明：1995~2010年徐州市睢宁县的农村居民点景观格局呈破碎化趋势，土地利用斑块数增加，斑块平均面积下降，面积加权平均形状指数上升，平均分维度小幅上升，散布与并列指数和香农多样性指数均在下降。

The sibelium 100μg intervenient group began to decrease a t reperfusion 24 h,and slowly fell but no reaching to the lowest level all along.

西比灵100 μg干预组于再灌注24小时开始下降，并于以后各时相继续缓慢下降并始终未达谷底。

In addition, the reagent in O-T method are more toxic and irritative, so GOD method adopted in this paper.The stability of INS in digestive secretion was investigated. The results show that the degradation rate in gastric solution was so fast that any pharmaceuticalmodification and adding enzyme inhibitors could not protect it.

在肠道吸收部位的研究中发现，INS溶液在大肠处给药可有微量吸收，但能引起动物血糖的明显下降，INS的水溶液和微乳液的吸收与药效无明显差异；在小肠处，INS溶液不能吸收，也不能引起大鼠血糖的降低，而制成微乳液后，可经小肠粘膜吸收，并引起血糖的明显下降。

"Our study shows that this decrease is not a transitory phenomenon, but persists and grows over time," Dr. de Jager and colleagues wrote in their analysis.

de Jager博士及其同事在分析中写道："我们的研究表明，这种下降并非一过性现象，而是持续存在，并随时间会继续下降。"

The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

胰岛素耐受实验和胰岛素敏感指数表明OP动物的胰岛素敏感性较OR动物下降，而OP大鼠血清中游离脂肪酸、酮体、肝脏总胆固醇和甘油三酯水平显著升高；但是，OP与OR大鼠血清中总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白和空腹血糖等的水平并无显著性差异；⑶肥胖易感与肥胖抵抗大鼠血清、尿液和肝脏组织提取物中代谢物的比较研究表明：①OP与OR大鼠的血清、尿液和肝组织提取物中多种氨基酸的含量存在显著差异，并以肝组织中的差异氨基酸数量为最多，包括各种生酮和生糖氨基酸水平在OP组的升高，说明氨基酸代谢的差异是两种体重表型大鼠之间存在的重要差异特征之一；②OP与OR动物肝脏和血清差异代谢物中包含多种饱和长链脂肪酸的升高如十四烷酸、十六烷酸、硬脂酸等和多不饱和脂肪酸的下降如亚油酸和花生四烯酸，说明两种体重表型动物的肝脏脂肪酸代谢存在明显差异；③长期高脂饮食喂养后，动物的尿液代谢物分析表明OP与OR动物体内的肠道菌群结构存在差异，这些菌群上的差别可能在动物体重增长的调节上产生影响；④与OR动物相比，OP动物尿液代谢物中儿茶酚胺类递质的代谢终产物如高香草酸、扁桃酸和4-羟基苯乙酸明显升高。

The Lace-up group's center of pressure displacement quantity is bigger than other two groups,therefore its balance ability is also bad, therefore suggested the athlete when wearing ankle braces sports should inquire specialized doctor and the protection suggestion avoids injury.

人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时， Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果，但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象，造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大，著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大，且Lace-up组在著地期压力中心偏移量也较其他两组大，故其平衡能力也有差异，故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
