sc1矿机计算器

A. 硅片清洗工序中，sc-1 sc-2化学清洗液PH值怎样算

标准RCA 溶液配比浓度大：SC1氨水：双氧水：水=1：1：5-1：2：7
SC2氯化氢：双氧水：水=1：1：6-1：2：8
氯化氢浓度37% 氨水浓度27% 双氧水30%

B. 我的计算器是这样的如何计算标准差

用EXCEL就是啦

C. java中Class.forName().newInstance()显示有错误

((Common)Class.forName(tool).newInstance()).calculateTime();

D. c语言编程

#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语言求大神有好评在线等

这个我就按照要填写的内容用序号来标注：
第一空：%f %f %f %f, &sc1,&sc2,&sc3,&sc4（这个是输入语句的格式，书本上最好看下概念）
第二空：( ( sc1 + sc2 + sc3 + sc4)/4 ) >= 80.0 （这个就是一个条件与酸腐语句的一部分，前面括号中表示的是求四门课的平均成绩，然后与80比较，后面部分的？表示的是进行判断，当满足大于等于80 的时候，结果是问号后面的是，反之则为否；
第三空：( (sc1>= 80.0) &&(sc2>=80.0)&&(sc3>=80.0)&&(sc4>=80.0)) ，同样的分析，只不过这个地方的&&表示的是逻辑运算符，表示的是且，就是同时的意思；
第四空：( (sc1>= 80.0) ||(sc2>=80.0)||(sc3>=80.0)||(sc4>=80.0)),将前面的且换成或，也就是说只要这四个之中满足一个就可以了，如果是真，则结果取问号后面第一个答案，反之去否；
第五空：没有一门大于等于80，则说明，四门课同时小于80，答案是( (sc1<80.0) &&(sc2<80.0)&&(sc3<80.0)&&(sc4<80.0))

F. JAVA代码运行不了 图形计算器

你这个怎么可能会看到你想要的效果呢，就新建了一个对象而已。要调用你的Main方法才会执行的。main函数里面应该是 System.out.println(new Main().Main());

G. 求VB计算器代码

H. Java循环,输入一个数，计算1到这个数的和

StringBuffer，循环完毕剪掉最后一个字符。用string也可以，但是费资源。
或者你写成
Scanner sc1 = new Scanner(System.in);
System.out.print("输入任意一个数:");
int c = sc1.nextInt();
System.out.print(1); //先打印处必定有的第一个数1
for(int i = 1;i<=c;i++){
System.out.print("+"+i);....//倒过来写就成了
