什么是学科分类号MASS 或 PACS
MASS 学科分类号 例如:
110 数学 110.11 数学史 110.14 数理逻辑与数学基础 110.1410 演绎逻辑学(亦称符号逻辑学) 110.1420 证明论(亦称元数学) 110.1430 递归论 110.1440 模型论 110.1450 公理集合论 110.1460 数学基础
PACS 物理学和天文学分类方案 ,即“Physics and Astronomy Classification Scheme”.如:
00—General(通用学科)
01. Communication, education, history, and philosophy(通讯、教育、历史和哲学)
02. Mathematical methods in physics(数理法)
10—The Physics of Elementary Particles and Fields(基本粒子物理学与场)
11. General theory of fields and particles(General theory of fields and particles(场和粒子的一般理论)
PACS 总分类标号如下(注:2010年始):
00—General
10—The Physics of Elementary Particles and Fields
20—Nuclear Physics
30—Atomic and Molecular Physics
40—Electromagnetism, Optics, Acoustics, Heat Transfer, Classical Mechanics, and Fluid Dynamics
50—Physics of Gases, Plasmas, and Electric Discharges
60—Condensed Matter: Structural, Mechanical and Thermal Properties
70—Condensed Matter: Electronic Structure, Electrical, Magnetic, and Optical Properties
80—Interdisciplinary Physics and Related Areas of Science and Technology
90—Geophysics, Astronomy, and Astrophysics
c语言 当一个数位数超过11位 怎么输入输出
#include <stdio.h>
void main()
{
__int64 a,n,N=1;//结果不超过18位的话可以用int64这个是64位的
__int64 sn,an;
printf("请输入a和n
");
scanf("%I64d%I64d",&a,&n);
printf("a=%I64d,n=%I64d
",a,n);
sn=an=0;
while(N<=n){
an=an*10+a;
sn=sn+an;
N++;
printf("%I64d %I64d
",an,sn);
}
printf("sn=%100I64d
",sn);
}
