旋转荷电球体外部引力场中引力效应

以实验粒子的短程线方程为出发点，计算了由旋转参量与电荷参量所引起的近日点进动效应．当粒子绕行方向与场源旋转方向一致时，与Kerr场中情况相比修正项将使进动效应增大．此外，通过引入局域洛伦兹空间截面，可给出该场中运动物体上加速度．显然在随动系中（vⁱ=0），从极轴方向和赤平面粒子均不能到达场源，而是分别停滞在r＝k＋(k²+4m²a²)^1/2/2m和r=k/m处．此时可以计算对星系尘埃的吸积作用，即尘埃的分布状况．最后还讨论了赤平面上作圆周运动物体（仅v³≠0）的类柯里奥利加速度 关键词：     

Cosmic Neutrino Oscillation or Separation

Current experiment results show that neutrinos have non-zero masses and that different neutrino flavours may mix and undergo a transformation to each other. Neglecting matter effects for simplicity and by solving the Friedmann-Robertson-Walker geodesic equations of the time-like particle, we preparatively investigate the vacuum oscillation or separation of neutrinos on the cosmic scale.     

A Possible Mechanism for the Origin of Ultrastrong Magnetic Field of Magnetars

Growing observations reveal that soft gamma-ray repeaters and anomalous x-ray pulsars are magnetars. Their magnetic fields may achieve 10^14 - 10^15G. We explore the origin of the superstrong magnetic field by considering the magnetization of the ^3P2 superfluid neutrons inside neutron stars （NSs）. By solving the Tolman-Oppenheimer-Volkov equations together with the equation of state adopted by Elgaroy it et al. [Phys. Rev. Lett. 77 （1996） 1428] in the calculation of the neutron pairing gap, we specifically calculate the NS internal structure, the permissible region for ^3P2 superfluid neutrons inside the NS, and the total magnetic moment contributed by the orderly arranged neutron vortexes. The result shows that the induced magnetic field may cover a wide range, which is consistent with the magnetic field predicted by the standard magnetic dipole radiation for pulsar spindown.     

水杨基萤光酮-溴化十六烷基三甲铵高灵敏分光光度法测定微量锰

近年,以非离子表面活性剂增溶,用吡啶偶氮类显色剂在水相测定微量锰的光度法获得了较好的结果。用水杨基萤光酮-表面活性剂体系光度法测定微量锰的研究尚未见报导。本文探讨了用水杨基萤光酮-溴化十六烷基三甲铵体系光度法测定锰的最佳条件。试验表明,在pH8.6～9.8范围内,锰与水杨基萤光酮和溴化十六烷基三甲铵生成可溶于水的蓝紫色络合物,最大吸收波长为562nm,摩尔吸光系数高达1.31×10~5,是目前水相介质中光度法测定锰灵敏度最高的体系。
