By taking the energy integral as Lyapunov function, it is proved that nonlinear transverse vibrations of the beam undergoing uniform extension or retrieval are stable when there are not controlling moment in the central rigid body and driving force on the beam, according to the partial stable theorem.

利用能量积分构造Lyapunov函数，根据部分变量稳定性定理，证明等速伸展或收缩梁的横向非线性振动稳定。

Compliance with the postcorrection abduction bracing protocol is crucial to avoid recurrence of a clubfoot deformity treated with the Ponseti method.

对于接受Ponseti方法处理的畸形足患儿，其对于矫正后伸展器械的顺应性是最重要的因素。

Recurrence, defined as the need for any subsequent operatie treatment, was analyzed with respect to the seerity at presentation, the time of presentation, the number of casts needed to obtain the initial correction, any family history of clubfoot, ethnicity, and the compliance with postcorrection abduction bracing.

我们仔细分析了作为需要接受另外手术处理的标志的复发情况，主要包括症状出现的严重情况、症状出现的时间、达到初始矫正疗效的处理的次数、畸形足的家族史、种族倾向以及矫正后的伸展器械使用情况等几个方面。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
