The intersection and interpenetrate of life science and engineering science are the conspicuous character of recent development of science and tenology. Envoluation, as an important self-adapt method drawn from life phenomena, has been generally recongnized and widely applied to problem solving. But the current evolving models have a common deficiency: they can not well reflect that the evoluation of the system is in fact the co-evolution under numerous local reciprocity.

生命科学与工程科学的相互交叉、相互渗透和相互促进是近代科学技术发展的显著特点之一，进化行为作为从生命现象中抽取的重要的自适应机制已被人们普遍认识并得到了广泛的应用，然而现有的进化模型存在一个共同的不足——未能很好地反映出一个普遍存在的事实：多数情况下，整个系统复杂的自适应进化过程，事实上，是一个构成系统的众多子系统局部相互作用的协同进化过程。

This research design each intersection offset by relative offset, and derive a "the expected value of progressive intersection number model". This research is for the sake of improving the traditional bandwidth method which is unable to accord with progression demand of every intersection to assign the progression ability effectively, and know the vehicles' real progression ability in the arterial system.

由於群组划分后各子系统路口时差以「绝对时差」进行设计，将无法直接进行相异周期之群组间路口时差最佳化求解，本研究遂以「相对时差」进行各路口间时差设定，并推导一「续进路口数期望值」模式，以改善传统绿灯带宽法无法依据各路口续进方向之交通需求量，有效分配各路口双向续进能力，且无法由绿灯带宽得知系统内车辆真实的续进能力之问题。

The possible use of a sub-system acquiring data from several wireless sensors with minimal intrusiveness is both worth investigating and achievable.

In this method, an interim variable is defined by combining one variable of each subsystem. The interim variable is used to construct the sliding-mode function and the total control law can be derived to guarantee the equilibrium point is reachable in finite time. Using LaSalle invariance theorem, it can be proved further that the equilibrium field only includes one equilibrium point and the equilibrium point is asymptotically stable.

该方法将各个子系统的一个变量进行组合定义成一个中间变量，然后从这个中间变量出发构造滑模函数，通过求取总的控制量保证中间变量在有限时间内收敛到平衡点；进一步利用LaSalle不变性原理证明该收敛域内只有一个平衡点且是渐近稳定的。

Based on this notion and the invariance principle, a condition is proposed and proved, under which an invariant set of states of a switched system with Lyapunov stable subsystems can be stabilized by state feedback.

In order to solve these problems, this paper combines control technology and transducer technology to research constant pressure water supply system. Two independent sub-systems are irrespectively built with water place sensor and pressure sensor.

为了解决这些问题，本文采用控制技术和变频调速技术相结合的方法来研究恒压供水系统，该系统与现场液位传感器、压力传感器一起组成了两个独立的闭环控制子系统。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
