The principle of circuit is presented , and also the principle a ~ nd design consideration of the flyback converter . to establish the foundation of following design , the paper deduces the calculative formulas of the main ciituit parameters 分析了电路的工作原理,对反激变换器的原理与设计做了详细的介绍,推导了电路主要参数的计算公式,为下一步设计奠定了基础。
Thorough study has been done to solve the problems . a fast cct calculative method was suggested which could satisfy the precision need , the method was applied in the preventive control of the generator outputs 本文正是着眼于上述问题,进行了大量的研究工作,提出了一种快速的能满足精度要求的临界切除时间的计算方法,并将该方法应用于发电机出力的预防控制之中。
Abstract : in this paper , put forward the integrated calculate of layout element in the common curve layout method , simplified calculative process of layout element , layout method was adopted agilely , and needless recalculate layout element 文摘:提出了曲线常用测设方法的测设元素的一体化计算,简化了测设元素的计算过程,使测设方法能灵活采用,不需重新计算测设元素。
While the chinese ancient maths culture is on the culture layer of application and skills ? the material culture layer . in terms of the thinking pattern , the characteristics of chinese maths is practical , calculative , inductive and modelized 就思维模式来说,中国数学的特点是实用性、计算性、归纳性及模型化;西方数学的特点是演绎性、抽象化、公理化及思维创造性。
