Standard test method for analytical procedure determining transmissivity , storage coefficient , and anisotropy ratio from a network of partially penetrating wells 测定不完整渗透井网络过滤系数储藏系数和各向异性比率的标准试验方法
And then , we specially study the effect of spin interaction ' s anisotropy on the critical temperature tc . from what we have observed we suggest that the critical temperatur tc grows as the anisotropy intensifies , while the system magnetization becomes weaker . the system becomes id if the anisotropy ratio r goes to infinity , and its equilibrium state keeps zero magnetization at any finite temperature , which confirm that there is no observable transition for id system 其后,着重研究了自旋相互作用的各向异性程度r对其临界温度t _ c的影响,总结出:随着系统各向异性程度的增强,系统的临界温度向高温转移,而系统的磁化强度在不断的减弱;当r趋近于无穷大时,系统演变为一维系统,系统在任何有限温度下达到的平衡态始终保持磁化强度为零,这也证实了一维系统不发生相变
