  • But when computing deep subcritical system , it has some difficulty inevitably . the reason is studied from both ration calculation and qualitative analysis
    作参数的尝试插值法是计算通常采用的方法,计算精度较高,但在深次临界情形下存在难以避免的困难。
  • But the theoretical computation of a eigenvalue has some special difficulty . the iteration procedure is likely to diverge in deep subcritical system and lead to calculation failure
    但的理论计算存在特殊的困难,尤其是对于深次临界情形,容易发生迭代过程不收敛情况,导致计算失效。
  • As a elementary explore , three sn programs are written in this paper to compute a eigenvalue in deep subcritical system using different methods . the k indirect method is a common method to compute a and it has the advantage of high precision
    本文编制了采用三种不同计算方法独立计算本征值的多群s _ n (离散纵标)程序,且用这三种程序初步计算了深次临界情形下的本征值。
  • The conclusion is that when , the energy group g will be supercritical , so the iteration will not converge and the computation will fail . it ' s not appropriate to set - to the left side of neutron transport equation when computing in deep subcritical system . the r indirect method deals with / v according to actual situation
    本文从定量计算和定性分析两方面研究了深次临界情形下本征值计算存在困难的原因,指出当满足关系_ ( t , g ) + / _ g _ ( s , g g )时,对该能群来说可能会处于单能群意义上的超临界,导致迭代发散,计算失效。
  • When a < 0 , move / v to the right side and look upon it as source term . the calculation result shows that the r indirect method can compute deeper than k indirect method in subcritical system . but the y indirect method has no inner iteration , it ca n ' t ensure the convergence of neutron flux and it will also fail in deep subcritical
    作参数的尝试插值法把/分情况处理,当由插值法得到的新值大于零时,仍将/放在输运方程左端作为吸收项,若0 ,则将其移至右端作为源项处理计算表明,该方法比作参数的尝试插值法算得的次临界度深一些,但由于没有内迭代过程,不能保证通量收敛,在深次临界情形下同样会失效。
  • In this paper , we mainly discuss the topological structure of several classes of special fourth polynomial differential systems with the first and the third critical singular point . as in paper [ l ] , mr han yuliang have discussed the system in the first critical case and the system in the third critical case ( where b , a30 0 in system ( l ) and ( 2 ) ) here , we use the tools and method of paper [ l ] , to study the system where , 040 , b04r - { 0 } , where , 640 , ao4r - { 0 } , 631 , 622513 , b04er for the system ( 3 ) and ( 4 ) , because of their only one finite singular points , and they are saddle - nodes , we can easily give the result that there is no limit cycle in their phase portrait
    本文主要是研究在第一及第三临界情形下的几类特殊四次多项式微分系统的全局拓扑结构,在文献中,韩玉良主要考虑了第一临界情形下的系统及第三临界情形下的系统的全局结构,并画出它们所有可能的全局相图, (在( 1 ) , ( 2 )中, b : a _ ( 30 ) 0 )本文根据文献的工具和方法,考虑系统:其中,以及系统其中,这样,由于等号右端多项式次数的增加,极限环的存在性问题变简单了,但讨论系统的全局结构时,特别是作全局相图时,难度增大了。
