sc1礦機計算器
A. 矽片清洗工序中，sc-1 sc-2化學清洗液PH值怎樣算
標准RCA 溶液配比濃度大：SC1氨水：雙氧水：水=1：1：5-1：2：7
SC2氯化氫：雙氧水：水=1：1：6-1：2：8
氯化氫濃度37% 氨水濃度27% 雙氧水30%
B. 我的計算器是這樣的如何計算標准差
用EXCEL就是啦
C. java中Class.forName().newInstance()顯示有錯誤
((Common)Class.forName(tool).newInstance()).calculateTime();
D. c語言編程
#include <stdio.h>
#include <math.h>
int main()
{short int a1,b1,a2,b2;
scanf("%3hd%4hd%3hd%4hd",&a1,&a2,&b1,&b2);
a1+=b1;
a2+=b2;
if(a2>9999){a1++;a2-=10000;}
printf("a+b=%hd%04hd ",a1,a2);
return 0;
}
E. C語言求大神有好評在線等
這個我就按照要填寫的內容用序號來標註：
第一空：%f %f %f %f, &sc1,&sc2,&sc3,&sc4（這個是輸入語句的格式，書本上最好看下概念）
第二空：( ( sc1 + sc2 + sc3 + sc4)/4 ) >= 80.0 （這個就是一個條件與酸腐語句的一部分，前面括弧中表示的是求四門課的平均成績，然後與80比較，後面部分的？表示的是進行判斷，當滿足大於等於80 的時候，結果是問號後面的是，反之則為否；
第三空：( (sc1>= 80.0) &&(sc2>=80.0)&&(sc3>=80.0)&&(sc4>=80.0)) ，同樣的分析，只不過這個地方的&&表示的是邏輯運算符，表示的是且，就是同時的意思；
第四空：( (sc1>= 80.0) ||(sc2>=80.0)||(sc3>=80.0)||(sc4>=80.0)),將前面的且換成或，也就是說只要這四個之中滿足一個就可以了，如果是真，則結果取問號後面第一個答案，反之去否；
第五空：沒有一門大於等於80，則說明，四門課同時小於80，答案是( (sc1<80.0) &&(sc2<80.0)&&(sc3<80.0)&&(sc4<80.0))
F. JAVA代碼運行不了 圖形計算器
你這個怎麼可能會看到你想要的效果呢，就新建了一個對象而已。要調用你的Main方法才會執行的。main函數裡面應該是 System.out.println(new Main().Main());
G. 求VB計算器代碼

H. Java循環,輸入一個數，計算1到這個數的和
StringBuffer，循環完畢剪掉最後一個字元。用string也可以，但是費資源。
或者你寫成
Scanner sc1 = new Scanner(System.in);
System.out.print("輸入任意一個數:");
int c = sc1.nextInt();
System.out.print(1); //先列印處必定有的第一個數1
for(int i = 1;i<=c;i++){
System.out.print("+"+i);....//倒過來寫就成了
