Experiment research on continuous brake of passenger car;

The continuous brake control system with engine brake, exhaust brake and retarder is put forward in order to deal with the problem of low brake torque with engine brake and exhaust brake of bus.

Taking Taiyuan City as the example,this paper expounds the features of the ecological environment for the garden plants,and puts forward some strategies and methods for the sustainable control of the garden plants pests.

Different levels of intermediate cutting intensities for the stands have different sustainable control effects of T.

The result showed that the sustainable management of Nosema locustae to grasshopper was apparent.

, a new set of techniques by mainly applying the microsporangium Nosema locustae and sometimes cascade (one of the acylurine chemicals having acdysis inhibition activity) in addition for sustainable management of the locust disaster originally from abandoned land wa.

Feedforward and feedback optimal control for linear large-scale systems with state time-delay affected by persistent disturbances;

Optimal tracking control for nonlinear systems with persistent disturbances;

Feedforward and feedback optimal control for linear systems with persistent disturbances;

The two theorems are improved with respect to partial uniformly asymptotic stability and partial asymptotic stability under continuous perturbation by lowering dimension of vectors, which improves and generalizes the existed conclusions in relevant literatures.

The strong stability and strong asymptotic stability of differential equations under continuous perturbation on partial variables are studied by using Liapunov functions.
