By adding an equivalent harmonic impedance in the branch circuit of power grid, this HAPF could force all the harmonic currents flow into passive power filters, which resulting in eliminating harmonic contamination more effective. And using the capacitive feature of PPF in the fundamental frequency, this HAPF could compensate fixed-capacity reactive power without increasing APF's burden. Moreover, in order to decrease APF's cost, the fundamental voltage will largely be endured by capacitor in view of the series resonance circuit tuned at the fundamental frequency, so the APF just bears little harmonic voltages.

其基本工作原理是：有源部分等效于在电网支路中串联了一个谐波阻抗，该谐波阻抗对基波电流不起作用，而对谐波电流产生很大阻碍作用，迫使谐波电流流入无源滤波器，从而达到滤除谐波的目的；同时新型注入式混合有源滤波器还充分利用了无源滤波器的无功补偿功能，在不增加有源部分容量的前提下，可以提供一定容量的无功功率；由于有源部分承受的电网基波电压不大，也没有基波电流流入，因此逆变器容量小，初期投资较小。

Thus,in combination with neutron,resistivity and density logging,this paper reconstructs feature parameters K1,K2and establishes K1-K2 pattern which can qualitative evaluate gas AOF.Additionally,in the light of different reflection toward gas between neutron and density logging,a relation between test nonresistance outflow and gas-bearing content which varies with different neutron and density logging is built,thus the gas AOF can be quantitative evaluation.

objectiveto evaluate the result of using rectangular advacement flaps for repairing the eyelid defects at the edges of palpebra.methodswe have used rectangular or double rectangular advacement flaps to repair the defects of theantieror margin of eyelid in 36 cases.to repair the posterior margin defects ,when the defects of thetarsal plates were shorter than 5mm,the tarsal plates were closed directly , longer than 5mm ,sliding tarsal palpebral conjunctive flaps were to be used.resultsin 36 cases all of the flaps were survived with primary healing, slight scar, no absence of eyelashes, no notch deformity at the edge of palpebra, no trichiasis.

目的：探讨应用矩形推进皮瓣修复睑缘眼睑缺损的效果。方法：对36例睑缘肿物切除的眼睑缺损患者，采用矩形或双矩形推进皮瓣修复眼睑前层缺损。眼睑后层睑板缺损小于5mm者，采用直接缝合法；睑板缺损大于5mm者，采用睑板睑结膜瓣移行法。结果：36例患者皮瓣全部成活，切口ⅰ期愈合，手术瘢痕轻微﹑睫毛无缺失﹑无倒睫﹑睑缘圆滑无切迹畸形。

The results show that with the sea level rise, amphidromic point in this sea area tends to move to the southeast, and then coastal tidal ranges change present consequently different features ,that is,at the left side and bayhead coast near the amphidromic point they change evidently, and little at the right side and bayhead coast far away from amphidromic point.

将南黄海概化为一等深矩形海疆，初阶研究了在海平面上升3m 和 5m 前提下该海疆扭转潮波体系的演化趋势，继而剖析了沿岸潮差厘革特性。初阶分析研究剖明：跟着海平面上升，该海疆 M2 分潮的无潮点有向东南标的目的偏移的趋势，受此影响，沿岸潮差泛起差此外厘革特性，接近无潮点的左侧及湾顶海岸厘革较着，而阔别无潮点的右侧及湾顶海岸则厘革不年夜。
