1. For a class of quasi - one - dimensional cluster , we study the effect of side spins on the spin - spin correlation on chain , our calculations show that the side spins added in the same sublattice can effectively strengthen the spin - spin correlation in large distance region and make the change tend to flat
   計算證明，側(cè)自旋加進相同的子格中能有效地加強自旋關(guān)聯(lián)使得它在長距離范圍內(nèi)的變化趨于平緩，而周期性地加入側(cè)自旋可以在基態(tài)中建立磁性長程序。
2. The calculation determined the main point defect under different cd pressure and the reaction enthalpies and entropies and the equilibrium constants in ( cd , zn ) te according to the quasi - chemical equations written for cdte sublattice . also the recipe of two - zone annealing process for cd0
   根據(jù)計算結(jié)果，確定了不同氣氛條件下cd _ ( 1 - x ) zn _ xte ( x = 0 . 05 )晶體中占主要地位的點缺陷和相關(guān)偽化學(xué)反應(yīng)式的反應(yīng)焓、反應(yīng)熵及平衡常數(shù)，給出了兩溫區(qū)本征退火的具體參數(shù)。
3. In this dissertation , we characterize the congruences on a strong semilattice of semigroups by the congruences on those semigroups and prove that a sublattice of the direct product of the lattices of congruences on those semigroups is isomorphic to a sublattice of the lattice of congruences on the strong semilattice of semigroups
   本文，我們主要利用一族半群上的同余刻劃其強半格上的同余，并討論這族半群的同余格的直積的子格與其強半格上的同余子格的關(guān)系。
4. The study shows that the former is main reason of the reentrant phase transition of system , while the later is not contribute to reentrant phase transition . on the other hand , when the crystal field is small , magnification of the range of magnetic ordering phase at low temperatures come from the contribution of spin - 1 sublattice , while the result is not discovered in spin - 1 / 2 sublattice
   晶場存在時，前者是系統(tǒng)重入相變的主要原因，而后者對重入相變沒有貢獻；另一方面在較小晶場存在時低溫區(qū)磁有序相范圍的擴大來自于自旋1子格中橫場及隨機的作用，而自旋1 2子格沒有發(fā)現(xiàn)類似現(xiàn)象。
5. In two - component model of hydrogen - bonded chains , the system with nonlinear and linear coupling between proton sublattice and heavy - ion sublattice is investigated . fast - mode soliton pair and slow - mode soliton pair are obtained . as for fast - mode soliton the effective mass of the kink in the proton sublattice decreases due to the nonlinear coupling and increases due to the linear coupling . for slow - mode soliton , the thing is quite opposite to that of fast - mode soliton
   在氫鍵鏈二分量模型中，研究質(zhì)子子晶格和重離子子晶格相互作用項中同時含有非線性耦合和線性耦合兩部分的系統(tǒng)，得到快模孤子偶和慢模孤子偶.對于慢模孤子而言，非線性耦合降低了質(zhì)子子晶格中孤子的有效質(zhì)量，而線性耦合增加了質(zhì)子子晶格中孤子的有效質(zhì)量；對于快模孤子而言，情況正好相反
