The following results have been obtained mainly from Monte-Carlo simulation studies using SR8000 (VPP500) at KEK and VPP700 at RIKEN: (1) full QCD : International collaboration with DESY and ITEP groups has begun. Preliminary data shows monopole density is much higer than that in the quenched case. (2) pure SU (3) QCD: Almost perfect monopole action for constrained three monopole currents is fixed. The static potential, the string tension and the glueball mass are evaluated. (3) Gauge (in) dependence of abelian dominance: Gauge independence of the monopole physics are studied using various block-spin transformations with various gauges. (4) Flux of electric field and magnetic current around Abrikosov vortex is measured in SU2 QCD and results are consistent with those of the dual Meissner effect.(5) Simulations of DGL theory: The electric-field flux distribution is measured in DGL theory numerically which looks similar to that of QCD. (6) T≠0 QCD: From the simulations on anisotropic lattice, monopole actions showing the continuum scaling are obtained. The Coulomb-gas picture of monopoles can describe well non-perturbative effects in the high temperature phase of QCD.(7) Blocking from the continuum theory is performed successfully. The obtained lattice action is shown to be compatible with that derived numerically.

以下结果主要是从Riken的Kek和VPP700的SR8000（VPP500）的Monte-Carlo模拟研究中获得的：（1）完整的QCD：与DESY和ITEP组的国际合作已经开始。初步数据显示，单极密度远高于淬火情况。 （2）纯SU（3）QCD：固定了约束三个单极电流的几乎完美的单极作用。评估了静态电势，弦张力和粘合球质量。 （3）Abelian优势的量规（IN）依赖性：使用各种仪表的各种宽旋转转换研究了单极物理学的规格独立性。 （4）在SU2 QCD中测量了Abrikosov涡流周围的电场和磁电流的通量，结果与双Meissner效应的结果一致。 （5）DGL理论的模拟：在数值上以DGL理论测量电场通量分布，该理论看起来与QCD相似。 （6）t≠0 qCD：从各向异性晶格上的模拟中，获得了显示持续缩放的单极作用。单孔的库仑气体图片可以在QCD的高温阶段描述良好的非扰动效应。（7）从继续进行的理论中阻止了持续的理论。所获得的晶格作用显示与数值衍生的作用兼容。
