In the first two years, different topics on lattice field theories were studied in each group organized by the participants of this project. Main results are the following :1) Large-scale Monte-Carlo simulations using very large paralell super computers were done in the lattice quantum chromodynamics (QCD). Hadron masses and matrix elements, heavy quark system, finite-temperature transition of QCD were studied. It is to be emphasized that Tsukuba group has clarified the features of finite-temperature transition of QCD with Wilson fermions.2) Monopole condensation and color confinement were studied using Monte-Carlo simulations of lattice SU (2) and SU (3) QCD.The role of monopoles and the relation between monopoles and instantons were clarified by Kanazawa and Hiroshima groups. New idea and technique using block-spin transformation on the dual lattice were proposed and almost renormalized trajectory is found in terms of monopoles.In the last years, all the fund is devoted to organize Yukawa International Seminar on Non-perturbative QCD-Structure of the QCD vacuum- held at Institute of Theoretical physics at kyoto University from December 2 till December 12,1997.. Many members of the participants of this project were involved in the organizing commitee. The seminar is composed of 50 long talks and 38 short talks. In addition, three discussion hours were organized on color confinement and monopoles and instantons, renormalization transformation, hadron physics. The number of the total registered participants is 143.

在最初的两年中，在该项目的参与者组织的每个小组中研究了晶格场理论的不同主题。主要结果是：1）在晶格量子铬动力学（QCD）中完成了使用非常大的Paralell超级计算机的大规模蒙特卡洛模拟。研究了强子质量和基质元素，重夸克系统，QCD的有限温度过渡。需要强调的是，Tsukuba Group阐明了QCD与Wilson Fermions的有限温度过渡的特征。2）使用晶格SU（2）和SU（3）QCD的蒙特卡洛模拟单极凝结和QCD的蒙特卡洛模拟。提出了在双晶格上使用块旋转转换的新想法和技术，并在单孔方面找到了几乎重新归一化的轨迹。在过去的几年中，所有基金都致力于组织Yukawa International International研讨会，非扰动QCD QCD QCD实施QCD真空吸尘器的QCD QCD QCD QCD的QCD QCD QCD QCD QCD QCD QCD的许多成员在Kyototical Instriction 7中的成员持有。该项目参与组织委员。该研讨会由50场长时间的演讲和38个简短的演讲组成。此外，还组织了三个小时的讨论小时，并在颜色限制和单孔和激体孔中，重新归一化的转化，强子物理学。总注册参与者的数量为143。
