后平衡

The current signals were gathered in the tests, and processed by wavelet package transform. A characteristic vector was constructed by the energy of different frequency segment, which was calculated by using the coefficient of wavelet package transform of the current signals. The vector shows that the energy of low frequency segment is of the majority of the total energy, and becomes larger as the interelectrode gap decreasing.

在线采集真实电解加工过程中的电流信号，用对实测信号进行小波包分解和重构后的小波系数计算各频段的能量，构造一个由不同频段能量组成的特征向量，发现特征向量的低频分量占总能量的大部分，随着平衡间隙的减小，低频分量能量增大。

Results show that: productivity of Chinas service industry is overall increasing and shapes inverse U curve; technical progress is the primary increase factor of service industry's productivity and technical efficiency is the key constraint of service industry's productivity increase in China; regional development of service industry productivity in China is extremely unbalanced and east region has more increase advantage comparing with middle and west region.

研究结果表明，中国服务业的生产率总体上处于增长趋势，并呈现出先增后降的倒U型特征；技术进步是服务业生产率增长的主要因素，而技术效率则成为制约服务业生产率增长的关键原因；服务业生产率的区域发展极不平衡，东部地区具有明显的增长优势，而中西部地区的大多数省份发展滞后或缓慢。

Simultaneously, when the volume fractions of coexisting three-liquid-phases are converted into mass densities, it is also found that the coexisting curve of temperatures versus mass densities of phases is also standard inverse "S" type curve.

实验结果表明，在平衡共存三液相中，水、环己烷和二乙二醇丁醚的体积分数随温度改变的变化曲线分别是倒"S"型，正"S"型，"结"型；将共存三液相的体积分数转化为对应的相密度后，相密度随温度改变的变化曲线也是规整的倒"S"型；而且，3条"S"曲线形状均表现出不对称的特性。

In this paper, the conventional isopiestic technique have been modified and extended to multicomponent unsaturated mixed solvent solutions, each containing two or three volatile solvents and two unsaturated solutes, and multicomponent saturated aqueous solutions, each containing two unsaturated solutes and one or two saturated solutes. Isopiestic measurements have been conducted systematically for the first time for two mixed solvent electrolyte solutions, two quaternary saturated aqueous solutions and three quinary saturated aqueous solutions and the experimental results have been compared with the ideal-like solution model.

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。
