在单片机应用系统中，输出控制是单片机实现控制运算处理后，对控制对 象的输出通道接口。单片机主要输出三 种形态的信号：数字量，开关量和频率 量

4.3.1参数根轨迹一除K*之外其他参数变化时系统的根轨迹(s+a)/4 例2系统开环传递函数G(s)=2a=0→∞变化,绘制根轨迹;ξ=1时,(s)=?

Styles of kinematic GPS Kinematic GPS techniques go by a number of names with features that are often receiver specific Kinematic GPS: Early term which implies that there is no loss of lock while the receiver is moving. In survey mode, if loss of ock occurs the antenna must be returned to a point of know ocation

Symbol table: major inherited attribute and major data structure in a compiler Principal operations: – Insert: store the information provided by name declarations when processing these declarations – Lookup: retrieve the information associated to a name when that name is used in the associated code

Market Efficiency - Market Failures Recall that: Adam Smith’s “invisible hand” of the marketplace leads self￾interested buyers and sellers in a market to maximize the total benefit that society can derive from a market

一、 无进刀切削的制动控制 1. 动作示意图 工作台——电动机驱动工作台前进到位位置 工作台的原点 2. 动作过程 操作者的操作下，工作台自动从位置A运动到B，在B处停留一段时间后再回到A而停止

Generate executable code for a target machine that is a faithful representation of the semantics of the source code Depends not only on the characteristics of the source language but also on detailed information about the target architecture, the structure of the runtime environment, and the operating system running on the target machine

共价结合是靠两个原子各贡献一个电子，形成所谓的共价键。 元素周期表中第 IV 族元素 C( Z = 6 )、Si、Ge、Sn (灰锡)等晶体，属金刚石结构，为共价晶体。 共价键的现代理论以氢分子的量子理论为基础。 两个氢原子 A 和 B，在自由状态下时，各有一个电子，其归一化波函数： A B ϕ and ϕ 每个氢原子中的电子满足薛定谔方程：
