1 首先是自动计算质数ACCESS的主窗体视图；2 其中Here input the upper number，表示输入所计算的数值范围上限，查找100以内的质数，或是1000以内，甚至10000以内；The quantity of prime number，表示统计出在计算范围内质数的数量；Prime表则汇总数值范围内所有的质数合集；我们在计算上限内输入200，点击Calculate按钮，...
Prime number：质数，又称素数，指在大於1的自然数中，除了1和该数自身外，无法被其他自然数整除的数（也可定义为只有1与该数本身两个因数的数）。例如，5是个质数，因为其正因数只有1与5，而6则是个合数，因为除了1与6外，2与3也是其正因数。算术基本定理确立了质数於数论里的核心地位：任何大...
