多环节冲击测量系统方波响应时间的计算

实际的冲击高电压测量系统，通常由多个不同特性的环节组成．作者以最简洁的数学推导式，表达了多环节测量系统方波响应时间的计算方法。借助于这一计算方法．讨论了方波源波形非理想时，它对实际方波响应时间测量值的影响。所提出的反映原始方波质量的技术指标，可比“上升时间”更易确定，而且实用性强．

THE TRANSFER BEHAVIOUR OF SOME CATIONS AT WATER／NITROBENZENE INTERFACE BY SEMIDIFFERENTIAL CYCLIC VOLTAMMETRY

The transfer of Sr~(2+) and Ba~(2+) ion, facilitated by 18-Crown-6 present in the aqueous phase, and of succinylcholine ion at w/nb interface were investigated by semi-differential cyclic voltammetry. A good polarographic curve of succinylcholine ion dissolved in water was obtained in the system of 0.01 mol/l LiCl (w)——0.01 mol/l TBATPB (nb). The peak current is directly proportional to the concentration of SC~(2+) ion. It can be used for the determination of SC and the detection limit is 1.05×10~(-5) mol/l.The apparent D~w and D~(nb) have been estimated. The transfer of Sr~(2+) and of Ba~(2+) at the interface are facilitated by 18-Crown-6 present in the aqueous phase and the peak current is directly proportional to the concentration of 18-Crown-6 in water. This method can be used for the determination of the complexing agent and for the stability constant of the complex formed in the aqueous phase.All the experimental results are in keeping with the theoretical.

MFRG-DPIR FOR THE DISORDERED TRANSVERSE ISING MODEL

A new approximate scheme which is combined by the mean-field renormalization group theory (MFRG) with the discretized path-integral renormalization (DPIR) is employed in the study of the disordered tranverse Ising model (TIM). The critical properties of random-bonds Ising systems on a d-dimensional lattice are calculated with this new approximate scheme.
