简答2. 简述节流式流量计的工作原理。
流体流过管道中的节流件时,会发生流速的改变,在节流件的前后会产生差压。在一定条件下,流量与这一差压有单值确定的关系。
计算8.如图所示,用差压变送器测量液位,是否考虑零点迁移?迁移量是多少?如果液位在之间变化,求变送器的量程。

在此处作答:
请看下面的代码
1.StringBuffer sb = new StringBuffer(“abc”);
2.String s = new String(“abc”);
3.sb.append(“def”);
4.s.append(“def”);
5.sb.insert(1,”zzzz”);
6.s.concat(sb);
7.s.trim( );
下面说法正确的是:

要在一个单向链表中p所指向的结点之后插入一个s所指向的新结点,若链表中结点的指针域为next,可执行 p->next=s; s->next= p->next;的操作。
设有一个链栈,栈顶指针为hs,现有一个s所指向的结点要入栈,则可执行操作。hs=s;
s-> next=hs;
设有n阶对称矩阵A,用一维数组s压缩存储A的下三角元素,s的下标从零开始,元素 s[26]相应于A中的元素为a 7,5。
