ERH end-quenching method was us ed to determine the hardenability of four kinds hot-forging die steels with dee p-hardening and hence the order of their hardena
晶粒白云岩是川西坳陷雷口坡组四段上亚段最好的储集岩,其厚度大、分布广且孔隙度、渗透率高。区内晶粒白云岩成岩作用类型多样,主要有白云石化作用、压实作用、溶蚀作用、压
1 前言用电子计算机进行“透镜自动设计的方法”,作为光学设计工作的工具来说,现在感到是完全成熟了。这种自动设计方法,自从电子计算机出现以来,不仅仅作为单纯的计算工具,而且在设计过程中,可以频繁地观察计算机,所以也可以说由于积极灵活运用使重复工作得以自动化,结果,从设计周期的缩短、光学系统精度的提高、复杂化、多样化以及紧凑
