For example, Russia still needs foreign capital assistance from Europe and the US in a bid to resurrect its economy and stabilize development. According to Russian customs' statistical data, trade with the EU stood at 36.1% of that with the rest of the outside world in 2003, making the EU Russia's current largest trading partner. Furthermore, Russia is the EU's main source of oil and natural gas in line with its diversification policy on the importation of energy sources. The two sides have gone as far as to discuss four "common spaces" during a high level summit in Rome last November. The four areas of cooperation under consideration include economics, judicial, humanitarian and internal security, education and research and external security.

不过，自从冷战结束后，双方亦建立起紧密的经济合作关系，譬如：俄国在追求经济复苏、稳定与发展之过程中仍须欧美外资之助益；依据俄罗斯海关统计数据显示，二○○三年俄国对欧贸易占其对外贸易总额之三六E一％，欧盟已成为俄罗斯目前第一大贸易夥伴，而欧盟亦视俄罗斯之石油与天然气供应为其能源进口多元化政策的主要来源之一；双方甚至於去年十一月的罗马高峰会上已讨论到建立四个「共同空间」：经济、司法及人道与内部安全、教育及研究、外部安全。

This paper, aiming at the topology structure of voltage-source shunt APF with filter-injecting circuit, advances a rigid output inductance calculation method based on harmonic current analysis which can work out the optimum output inductance values according to different compensation objectives.

本文尚有如下值得磋商之处：1、在许多APF应用场合，谐波负荷并不是稳定的三相全桥整流感性负载，各次谐波的幅值和相位都是变化的，其最大电流变化率难以确定，此时如何设计其输出电抗器？
