雲母試樣是用劈裂的方法制備的，因此可以達到原子級的平滑程度。It is the main purpose of this paper to calculate the energy splitting of ground state and excited states induced by thermally assisted quantum tunneling. first, a brief introduction is given for the theoretical and experimental studies on the magnetic macroscopic quantum effects. then, spin tunneling in a uniaxial ferromagnetic particle in transverse magnetic field is converted to a pseudoparticle moving in effective double - well potential with the help of the effective potential description of quantum spin systems developed by ulyanov and zaslavskii. finally using the periodic instanton method we evaluate the transition amplitude, energy shift and prefactor of wkb exponential and the energy splitting of ground state and the tunneling rate for excited states induced by thermally assisted quantum tunneling are obtained
文章首先對磁性宏觀量子效應的理論和實驗方面作了簡單介紹，然後藉助于ulyanov和zaslavskii發展的一種等效勢描述方法，把外磁場沿難磁化軸方向時的自旋隧穿約化成在等效雙勢阱中運動的粒子，利用瞬子方法給出基態能級劈裂，最後利用周期瞬子方法分別計算了隧穿幅、能級移動以及wkb前因子，從而給出由於熱助量子隧穿引起的激發態的隧穿率。In the account and analyses, we take into account the temperature stress in the cases : the base course is not cracking and the base course has been cracked. according to case of the base course cracked, the stress intensity factor of crack tip has been counted. according to case of the base course not cracked, the bend experimentation, the snap experimentation, the fatigue experimentation and the compress experimentation have been done, in addition, according to the latter, the finite element analyses have been done to demonstrated the temperature stress and the prime location of the glasgrid
在分析計算中，主要考慮基層開裂前和基層開裂后兩種情況下的溫度應力場，對基層開裂后，裂縫尖端的應力強度因子進行了計算；對基層開裂前的溫度應力場進行了室內小梁彎曲實驗、劈裂實驗、疲勞實驗、壓縮實驗，結合有限元分析結果，論證了基層開裂前的溫度應力場及格柵的最佳鋪設位置；研究成果在寧夏古王路上進行了驗證。
