An optimal filter is designed specially for dq transform used in the voltage mea-surement of transfer switch,which is composed of lower-order notch filter and lower-order low pass filter with higher cut-off frequency in series.Its transfer function is presented by theoretical derivation.If the order is same,it is better in measuring the positive sequence of fundamental amplitude than the average filter and the low-pass filter.

针对转换开关电压检测法——dq变换设计了优化滤波器，该滤波器是利用低阶陷波滤波器和较高截止频率低阶低通滤波器串联形成的，通过理论推导给出了该滤波器的传递函数，在相同的滤波阶数下，该优化数字滤波器在提取基波正序幅值的性能比较中，优于平均值滤波法及低通数字滤波器法等。

The representation of sequences is very helpful for the research of their linear complexity,so this paper we first research trace representation of periodic sequences,and the trace representation of a New Generalized Cyclotomic Sequence of order two of length pq is given,then for 2~mp~n period binary sequences,where p is an odd prime and 2 is a primitive root modulo p~2,we present a relation-ship between the linear complexity and the minimum value k for which the k-error linear complexity is strictly less than the linear complexity and have the upper bound and lower bound of the value k, finally we discuss the k-error linear complexity of legendre sequences,also have the upper bound and lower bound of the value k,and discusses the situation where the linear complexity drop again for some Legendre sequences.

序列的表达形式对于其线性复杂度的研究是十分有帮助的，本文我们首先研究的是周期序列的迹表示，给出了2阶pq长度的扩展分圆序列的迹表示，然后讨论了周期为2~mp~n(m≥2)序列的线性复杂度与使得线性复杂度变小的最小的k值的关系，给出了k值的上界和下界，这里p为奇素数，2是模p~2的本原根，并通过例子讨论了其线性复杂度的稳定性，最后对Legendre序列k-错线性复杂度进行了分析，也给出了k值的上界和下界，并对某些Legendre序列讨论了线性复杂度再次下降的情况。

The four well-known skeleton hydro-power stations of West-East Electricity Transmission Project, named Xiangjiaba, Xiluodu, Baihetan and Wudongde from the lower reaches of Jinshajiang River to upriver reaches, are all distributed in this area. Based on the analysis of the resource exploitation and industry sustainable development status, current problems and future scenarios, the main conclusions go as follows:(1) There are abundant and varied agricultural resources, widely distributed mineral resources with valuable predominant minerals, potential tourism resources, but some main problems such as lower level of exploration and development, serious waste and pollution, restraints of financing and transportation and eco-environmental frangibility still call for immediate solution;(2) Regional economy develops fast but the overall level is low-farming and animal husbandry industries, In which crop-plantation takes the main part, dominates in the sectional structure of economy, and forestry and specialty industries need to be further developed. The existed restraints such as unbalanced structural and regional economic distribution, acute structural deficiency and low economic efficiency need to be cleared out, of the way to a sustainable future.

西电东送骨干工程的向家坝、溪洛渡、白鹤滩、乌东德四大水电站均分布在这一江段通过对该区域资源开发和产业发展的现状、问题和发展前景进行分析，得到如下主要结论：(1)该区域农业资源丰富多样，矿产资源分布广泛且优势矿种地位突出，旅游资源待开发潜力巨大，但是资源开发却面临着勘探开发程度不够、浪费污染严重、资金交通制约和生态环境脆弱等几大问题；(2)区域产业经济发展迅速但总体水平低，部门结构中以种植业为主的农牧业占主导，林牧业和特色产业有待进一步开发，产业发展面临着部类和区域不均衡、结构矛盾突出以及效益低下等问题的困扰。
