| 1. | Transverse field of rotor 转子横向场 |
| 2. | The dependence of the curie temperature on the thickness of the film , the surface interaction and the transverse field are investigated 研究了居里温度与薄膜厚度、表面赝自旋交换相互作用强度及横场的关系。 |
| 3. | But influence of the crystal field on critical transverse fields of two different sublattices is very similar if the value of the crystal field increases to a certain degree 而当晶场增大到一定程度时,它对两个子格的影响就基本相同。 |
| 4. | Furthermore , when spin - 1 / 2 and spin - 1 sublattiees are of the different transverse fields and trimodal random distributions , they play a very different role 进一步的研究发现自旋1 2子格和自旋1子格中的横场不同并伴有随机分布时对系统的相变特性的影响是不同的。 |
| 5. | However the magnitude of the longitudinal components is less than 1 % of the transverse field , when the size of cpw ' s is very small . so we can approximately consider the field in cpw ' s as tem wave 但是在一定条件下(主要是减小导带宽度) ,场的纵向分量很小,共面波导中的电磁场可近似看大连海事大学博士学位论文成是tem波。 |
| 6. | The existence a smaller crystal field can magnify magnetic ordering region at low temperatures and can depress one at high temperatures . the existence of a lager transverse field can a lso assist the occurrence of reentrant phenomena 在随机横场作用下的平方格子中,较小晶场的存在能使系统低温时的磁有序相范围增大;而较大的横场也有助于重入现象的出现。 |
| 7. | It is found that the enhancement of the long - range interaction will result in the increment of the phase transition temperature , the increase of the critical transverse field and the decrease of the critical size 采用超越平均场理论计算了长程相互作用对铁电薄膜的物理性质的影响,发现长程相互作用的增强将使铁电薄膜的居里温度升高、临界横场增大、临界尺寸下降。 |
| 8. | The dependence of the curie temperature and the critical transverse field on the long - range exponent is obtained . long - range effects on the pyroelectric coefficient and susceptibility of a ferroelectric bilayer with a ferroelectric interfacial coupling are investigated by use of the transverse ising model within the framework of mean field theory 同时还考察了长程相互作用对居里温度和临界横场的影响;界面、长程相互作用及横场对铁电双层膜的热电性质和介电性质的影响在本文的第三部分我们作了较为详细的研究。 |
| 9. | In the honeycomb lattice with random transverse field , a smaller crystal field cannot change the percolation threshold of critical transverse field . the reentrant phenomena shall appear at the range of certain random concentration when the transverse field takes a larger value , while the reentrant phenomena do not occur and when the transverse field take a smaller value 随机横场作用下的蜂窝格子中,较小晶场的存在并不能改变临界横场阈值;取较大横场值时在某些随机浓度范围内出现重入相变现象,而取较小横场值时则没有重入现象产生。 |
| 10. | We also find that the strong long - range interaction , the large transverse field and weak interfacial coupling can lead to the disappearance of some of the peaks of the pyroelectric coefficient and susceptibility of the ferroelectric bilayer . we believe that it is the reason why these phenomena always take place in the experimental studies 我们还发现,较强的长程相互作用,较大的横场以及相对较弱的界面耦合作用将会导致铁电双层薄膜的热电系数和介电极化率的某些峰消失,这可以用来解释在实验中常常观测不到热释电系数和介电极化率的某些峰值的原因。 |
