电 流: 电荷的定向移动叫做电流。电路中,电流常用I表示。电流分直流和交流两种。电流的大小和方向不随时间变化的叫做直流。电流的大小和方向随时间变化的叫做交流。电流的单位是安(A),也常用毫安(mA)或者微安(uA)做单位。1A=1000mA,1mA=1000uA。 电流可以用电流表测量。测量的时候,把电流表串联在电路中,要选择电流表指针接近满偏转的量程。这样可以防止电流过大而损坏电流表。

这是用于线性方程组求解的ILUK预处理算法的实现。在VC++编译通过。矩阵采用压缩稀疏行格式存储(CSR),采用如下结构存储:struct Distmatrix {double **ma int **ja,dimension,*nnzrow } 很容易移植到自己定义数值计算软件包中。经本人测试计算效率比Fortran写的高很多(比如与Sparskit2比较)。

hibernate一对多双向关联映射 一对多双向关联映射的方法 在"一"一端的集合中使用<key>标签,在对方表中加入一个外键指向"一"端 在"多"的一端采用<many-to-one> 注意:<key>标签指定的外键字段必须和<many-to-one>指定的外键一至,否则引用字段的错误 inverse和cascade inverse是关联关系的控制方向; cascade操作上的连锁反应
