電 流: 電荷的定向移動叫做電流。電路中,電流常用I表示。電流分直流和交流兩種。電流的大小和方向不隨時間變化的叫做直流。電流的大小和方向隨時間變化的叫做交流。電流的單位是安(A),也常用毫安(mA)或者微安(uA)做單位。1A=1000mA,1mA=1000uA。 電流可以用電流表測量。測量的時候,把電流表串聯在電路中,要選擇電流表指針接近滿偏轉的量程。這樣可以防止電流過大而損壞電流表。

這是用于線性方程組求解的ILUK預處理算法的實現。在VC++編譯通過。矩陣采用壓縮稀疏行格式存儲(CSR),采用如下結構存儲:struct Distmatrix {double **ma int **ja,dimension,*nnzrow } 很容易移植到自己定義數值計算軟件包中。經本人測試計算效率比Fortran寫的高很多(比如與Sparskit2比較)。
