Using lag\|correlation analysis method, in terpretative variances analysis method,phrase comparing method to the wavelet an alysis result,we not only gained the variation at different scales of the globa l temperature and El Nino signals,the location of the jump points and latent sca le of these series,but also indicated the magnitude,extent of the effect of exte rnal forcing factors on ...

利用小波分析方法，辅之以滞后相关分析、解释方差分析及位相对应比较方法，得到了气温变化及ENSO活动在各尺度层次上的变化，突变点位置及特征尺度，并确定了太阳活动、火山活动和温室效应等外强迫因子对气温及ENSO的影响尺度、幅度及响应时间。

During drilling process, forward and backward redressing can be played the role to repair and maintain the wall of a well, making trajectory of borehole as far as possible to achieve ideal leading to drilling difficultly because of hole shrinkage, and so on, at the moment , the forward and backward redressing of this stabilizer can be played cutting, to eliminate hole shrinkage phenomenon, thus saving time and cost for drilling.

可在钻起过程中起到休整井壁的作用，使井眼轨迹尽量达到理想状态，防止出现狗腿现象。特别是在起钻过程中，往往由于井眼缩径等原因导致起钻困难，此时，该稳定器上的倒划眼齿可起到切削作用，以消除缩径等现象，从而为钻井节省大量时间和费用。
