By means of simulink of Matlab, it is known that the method that electric field is strengthened and two damp holes are turned on can lead to transfer ratio of force to be fallen during the phase of low frequency; on the other hand, the method that electric field is weakened and two damp holes are turned off can lead to transfer ratio of force to be fallen during the phase of high frequency.

通过Matlab仿真计算可知，振动物体在低频阶段，加大电场和开启两阻尼孔能使力传递率较低；而在高频时，关闭电场和阻尼孔，其力传递率较小。

3 All lead competition routes shall be climbed on lead with the competitor belayed from below.

所有先锋比赛路线选手应以先锋攀登，下方确保为之。

A Lead: Routes are climbed on lead, with the competitor belayed from below, each quickdraw is clipped sequentially and the longest distance along the line of the route determines a competitor's ranking.

先锋赛：选手采先锋攀登，由下方确保。各个快扣根据规定事先依序挂上。选手沿路线之轴线的最大距离，决定其该场之名次。

A Lead: Routes are climbed on lead, with the competitor belayed from below, each quickdraw is clipped sequentially and the height attained (or, in the case of traverse or roof sections, the greatest distance along the line of the route) determines a competitor's ranking.

先锋赛：选手采先锋攀登，由下方确保。各个快扣根据规定事先依序挂上。选手以达到之高度（在横渡或天花板部份，沿其路线之轴线的最大距离）决定其该场之名次。

The method made lead and lag errors boil down to GPS errors, which could be emendated by map data on the basis of the observability of GPS errors along the vertical direction. A general Kalman filtering was constructed to process the information of corrected GPS and DRS later, Which decreased lead and lag errors in the integrated navigation system.

该方法是将超前滞后误差归结力为GPS误差，先利用GPS沿道路垂直方向上误差的可现测性进行GPS误差校正，再得校正的GPS信息与DRS信息进行卡尔曼滤波，从而喊少组合导航系统超前滞后误差。

The results showed that the extractive could increase the expelling lead,decrease the content of bone and live lead.

结果表明，绿豆提取物可以增加铅中毒大鼠的铅排出量，降低骨铅和肝铅。

The game flip-flopped. In Game 1 we played very well in the first half and had a one-point lead and I though they played very well in the first and had only a one-point lead.
