数控直流稳压电源源程序 本设计由两个电路模块构成：直流稳压源电路（+15V,+5V,-15V），程控电路。并且巧妙得反置使用D/A变换器。使程控输出电压0-9.9手动可调，步距为0.2V。并可预置电压值，采用LED同步显示。-NC DC power source circuit of the design of two modules: the source DC circuit (+15 V,+5 V,-15V), program-controlled circuit. And clever use of a reversal of D/A converter. So that the output voltage programmed manually adjustable 0-9.9, step to 0.2V. And preset voltage value, shows that the use of LED synchronization.

观察自然频率对振动模态的影响（固定阻尼系数），可对有强迫振动项 的情形进行观察，将阻尼系数和自然频率固定，选择一种 的形式，观察 对振动模态的影响。 2、对由方程刻画的单自由度阻尼系统做动画仿真，观察阻尼系数，固有频率以及强迫振动项 对弹簧振动的影响，并和振动曲线图进行对比，写出你的观察结论。 -1、To observe the natural frequency of the vibration mode of (fixed damping coefficient), may have forced vibration of items to observe the situation, the damping coefficient and natural frequency is fixed, choose a form of observation of the impact of vibration mode. 2, characterized by the equation of a single degree of freedom to do animated simulation of damping system to observe the damping coefficient, natural frequency and vibration forced vibration of the impact of spring items, and to compare and vibration curve, write your observations conclusions.

树是由n(n≥0)个结点组成的有限集合T。n=0的树称为空树；对n>0的树，有:(1)仅有一个特殊的结点称为根结点，根结点没有前驱结点；(2)当n>1时，除根结点外其余的结点分为m(m>0)个互不相交的有限集合T1,T2，…，Tm，其中每个集合Ti本身又是一棵结构和树类似的子树。 -Tree is n (n ≥ 0) consisting of nodes finite set T. n = 0 of the tree known as the empty tree for n> 0 of the tree, there is: (1) has only one special node called the root node, root node there is no precursor node (2) when n> 1 when, with the exception of root node except the node is divided into m (m> 0) a finite set of mutually exclusive cross-T1, T2, ..., Tm, one of each set Ti is itself a structure and are similar subtree tree .
