In this lecture, we will start from the general relative motion concepts introduced in lectures D11 and D12. and then apply them to describe the motion of 2D rigid bodies. We will think of a rigid body as a system of particles in which the distance between any two particles stays constant. The term 2-dimensional implies that particles move in parallel planes. This includes, for instance, a planar body moving within its plane

系统最优化分配按照 Wardrop第二法则,即使得路 网中总行驶时间最小进行交通量分配。 该方法适用于最大限度地使用现有道路系统的场 合。从径路选择角度,该分配方法与用户均衡分配法 中用户一直选择时间上的最短径路不同,它有必要让 用户选择最短径路以外的径路。从此种意义上说,是 道路规划者或道路管理者所希望的分配原则,尤其在 智能交通系统获得广泛应用之后

Determining wastewater flowrates and constituent mass loadings is a fundamental step in initiating the conceptual process design of wastewater treatment facilities. Reliable data for existing and projected flowrates affect the hydraulic characteristics, sizing, and operational considerations of the treatment system components. Constituent mass loading, the product of constituent concentration and flowrate

第一节计算机数据采集系统发展概况 采用计算机对生产过程进行监视和测量的系统,一般称 为数据采集系统(Data Acquisition System简称DAS),或称为 计算机安全监视系统、计算机信息处理系统、数据采集监视 和处理系统等

process can occur spontaneously is that the entropy changes of chemical reactions are not readily measured. Furthermore, the criterion of sponta- neity given in equation 2 requires that both the entropy change of the surroundings and that of the system of interest be known. These difficul- ties are obviated by using different thermodynar function called the free energy, which is denoted by the symbol G (or F, in the older literature)
