本论文利用HERMES实验装置上的27.6GeV纵向极化正电子束与固定不极化质子靶的深度非弹散射的实验原始数据，重建了10060个Λ超子候选事例，对该过程中核子内被撞击的u夸克在碎裂过程中转移到Λ超子的自旋S〓进行了分析。

The various effective interactions'(including DDME1,TW99,NL2,TM1,TM2,GL85 and GL97) influence on the constitute, equation of state and mass of neutron star are studied in the framework of relativistic mean field theory considering the interacting nucleons, hyperons and mesons system at finite temperature (T=20 MeV).

从相对论平均场（Relativistic Mean Field，RMF）理论出发，考虑核子、超子和介子的相互作用，研究了一定温度（T=20 MeV）下，各种不同相互作用参数组（DDME1、TW99、NL2、TM1、TM2、GL85和GL97）对中子星物质的粒子组成、状态方程和质量等的影响。

The pairing correlation is treated by BCS method and the isospin dependent pairing forces have been used.

For the first time, we studied isospin effects on the two particle correlation functions, the light particle multiplicity and their ratio in HIC''s at intermediate energies, and find they are sensitive probes for the density dependence of the symmetry energy.

在国际上首次研究了重离子碰撞中两核子关联函数和轻粒子产生的多重性及比率的同位旋效应，发现它们敏感于核物质对称能的密度相关性。

Jawbones metastasis is difficult to diagnose only by clinical examination. Past medical history, blood survey, radiographic and bone scintigraphic examinations can give us clue for differential diagnosis.

颚骨内转移癌不易单藉临床检查来诊断，在作切片检查之前，可藉著患者病史、放射学检查、血液生化检查、核子医学检查等等进行鉴别诊断。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
