It is shown that under the supervision of the monitoring functions, the switching of control signal will stop after a finite number of switching and the tracking error will converge to a residual set that can be made arbitrarily small by choosing some design parameters sufficiently small.

进而证明，当被控对象相对阶大于1、高频增益符号未知时，在监控函数的监测下，相关控制信号经至多有限次切换后将停止切换，跟踪误差将收敛到一个残集内，且该残集可通过减小某些设计参数而变得任意小。

Lastly,we present an algorithm to isolate real roots of a univariate spline, i.e., computing asequence of disjoint intervals such that each of them contains exactly one real root of agiven spline function, which is primarily based on the use of Descartes\' rule of signs withits B-spline coefficients and de Casteljau algorithm of B?

最后，基于B-样条系数的Descartes符号准则和Bézier曲线的de Casteljau算法，我们给出了一元样条实根分离算法，也就是计算出一列不相交区间，使得每个区间恰好只包含此样条函数的一个实根。

Finally, taking these dates and using it as the functions of genetic program, and using the standard arithmetic operation as the terminals of GP. The object in this algorithm is the chiller consumption energy. Through the option of GP which contains 'crossover'、 'reproduce' and 'mutation' to iterant compute the population is composed of functions and the terminals of GP. Finally, we would find the consumption energy model of chiller.
