多负载非接触电能传输系统传输效率方程

为研究非接触电能传输（Contactless Power Transfer,CPT）技术,针对简化CPT模型的适用范围问题,将美国学者KIANI的工作推进到多负载系统.首先分别利用电路理论(Circuit Theory, CT)和耦合模理论(Coupled Mode Theory, CMT)得到两线圈感应连接的能量传输效率方程,结果显示这两种理论求出的传输效率方程是一致的.这个结论对3个线圈,4个线圈,……,n-1个线圈都成立.最后对单负载和双负载的结论进行物理验证.结果表明, 在系统的谐振频率处,多负载CPT系统CMT下的效率计算公式与CT下的计算公式完全等效.

和谐社会视野下关于农民负担问题的思考

农民问题是“三农”问题的核心,农民负担过重问题一直困扰着我国农村经济社会的稳定持续发展,成为构建社会主义和谐社会的一个重要制约因素。造成我国农民负担过重的主要原因有:城市偏向政策和制度;乡镇机构臃肿;一些地方政府搞形式主义,实施“政绩工程”。给农民真正落实“国民待遇”;改革乡镇机构,精简乡镇机构人员;完善农业农村立法,强化监督;建立维护农民合法权益的组织,是当前减轻农民负担的主要对策。

录像机重放系统中的伪时基校正原理

在录像机中，录放两种状态的头带相对运动不可能做到完全一致，因而重放的视频信号中必定存在时基误差，这将使图像彩色的不失真重现受到影响，用伪时基校正的方法可以从一定程度上消除这种影响．

The effect of deloading tape on medial gastrocnemius muscle fascicle behaviour during dynamic exercise

This study examined the effect of diamond deloading tape on medial gastrocnemius (MG) muscle behaviour during exercise in healthy adults (n = 27). A randomised cross-over trial assessed the effect of tape (no-tape, sham-tape and deload-tape) on ankle and MG fascicle kinematics during three heel raise-lower exercises [double leg (DL), single leg (SL) and loaded single leg (LSL)]. There was no effect of tape on standing fascicle length (FL) or pennation angle (PA), or ankle or knee joint angle. There was a significant effect of tape on ankle kinematics for all exercises. Both the deload-tape and sham-tape resulted in less ankle plantar flexion but had no effect on dorsiflexion. There was a significant effect of tape on FL change for the SL and LSL exercise. Compared to no-tape, the deload-tape resulted in less fascicle shortening during ankle plantar flexion, and more fascicle lengthening during ankle dorsiflexion. For the LSL exercise, deload-tape caused MG fascicles to operate at longer lengths, for a given joint angle. Diamond taping, with or without added tension, has only a small effect on ankle and MG fascicle kinematics during the heel raise-lower exercise. With the exception of the LSL exercise, both tape conditions resulted in similar changes in the FL-angle relations.     

Bar velocities capable of optimising the muscle power in strength-power exercises

This study aimed at testing whether there are mean propulsive velocities (MPVs) capable of maximising the mean propulsive power (MPP) during the execution of bench press (BP), bench throw (BT), half squat (HS) and jump squat (JS). Additionally, we assessed the differences in MPP/MPV between ballistic and traditional exercises. Seventeen male rugby sevens players performed MPP tests in BP, BT, HS and JS and maximum isometric force (MIF) tests in HS and BP. The JS presented higher MPP (977.4 ± 156.2 W) than the HS (897.9 ± 157.7 W) (P < 0.05); the BP (743.4 ± 100.1 W) presented higher MPP than the BT (697.8 ± 70.4 W) (P < 0.05). Ballistic exercises presented higher optimum MPV (JS = 1.02 ± 0.07 m·s^?1; BT = 1.67 ± 0.15 m·s^?1) than traditional exercises (HS = 0.93 ± 0.08 m·s^?1; BP = 1.40 ± 0.13 m·s^?1) (P < 0.05). The optimum MPP in the JS, BT, HS and BP occurred at 28.2 ± 5.79, 23.3 ± 4.24, 32.4 ± 9.46 and 27.7 ± 5.33% of the MIF, respectively. The coefficient of variation (CV) of MPV at optimum MPP ranged from 7.4% to 9.7%, while the CV of %MIF ranged from 18.2% to 29.2%. The MPV is a more precise indicator of the optimum loads than the percentages of MIF due to its low inter-subject variability as expressed by CV. Therefore, MPV can be used to determine the optimum power load in the four investigated exercises.
