The main contents of this thesis are:(1) The new phase segregated current differential protection based on distributed parameter is proposed. The new protection can calculate the current at the fault point in real time, so its performance is hardly affected by distributed capacitance of transmission line.

本论文主要内容包括以下几个方面：(1)提出了基于分布参数的分相电流差动保护新原理，该原理本质在于实时计算线路的故障点电流，因此其性能基本不受分布电容的影响。

We also used diffusion equation to solve curren-time relation of ion diffusion under certain boundary conditions.

Unstable electric current and voltage are the most two environmental killers for IC board,"High stable IC board" means having the ability to resist compression toward disorderliness electric current and voltage.

一片优质的IC板不仅具备多项功能，更重要的是具有『高稳定性』；IC 板的外在环境头号杀手是不稳定的电流、电压，『高稳定性』乃是指对紊乱的电流、电压有抗干扰性。

ERPs were recorded using oddball paradigm. In both high risk groups, P300 was reduced as compared to their sex/age matched normal controls. Reduction of P300 cortical current density was observed in temporal region with left dominancy in SPD subjects. The siblings of schizophrenia showed reduction of P300 cortical current density in the right frontal region.

与性别 /年龄相匹配的正常人群相比，这两组高危人群的 P300 减少，分裂型人格障碍人群的左侧优势半球颞区的 P300 皮层电流密度减少，而分裂症同胞则右侧额叶区 P300 皮层电流密度减少。
