英文
nuclear state vector-
This should be an incentive to apply the rrpa method with non - linear effective lagrangians to study other systems such as unstable nuclei near drip lines. for nuclei with the extreme value of n / z, low - lying collective excitations are found in isovector dipole modes, which are mainly due to the particle - hole excitation of weakly bound states near fermi surface and the isospin mixture effect
將相對論無規位相近似理論推廣應用到奇特核集體激發態的研究，發現對于奇特核的同位旋矢量激發模式在很低能量下會出現軟模式的巨偶極共振，這主要是由於費米面附近粒子-空穴激發所形成的。The relativistic random phase approximation ( rrpa ) is a relativistic extension of the random phase approximation for studying microscopically nuclear dynamical excitations and giant resonances. the consistency of rrpa calculations requires two aspects : first, it demands that the relativistic mean - field wave " function of nucleus and the particle - hole residual interactions in the rrpa are calculated in a same effective lagrangian. second, the consistent treatment of rrpa within rmf approximation requires the configurations including not only the pairs formed from the occupied fermi states and unoccupied stat es but also the pairs formed from the dirac states and occupied fermi states
自洽的相對論無規位相近似理論的自洽性要求有兩方面的內容：第一，描述原子核的激發態性質和基態性質時必須從同一個有效的拉矢量出發；第二，相對論無規位相近似計算，不但要考慮正能的粒子-空穴組態的貢獻，而且還要考慮從fermi海核子態到dirac海負能核子態形成的對激發的貢獻。A new all - digital fuzzy direct torque control servo system of pmsm based on dsp ( tms320lf2407a ) is designed and constructed, in which the traditional space voltage vector selector is replaced by an analytic fuzzy control state selector
摘要提出在pmsm直接轉矩控制系統中，採用解析模糊控制狀態選擇器替代傳統的空間電壓矢量選擇器的新型控制方法，設計完成了基於dsp （ tms320lf2407a ）為核心的全數字模糊直接轉矩控制系統。
