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。

The results of the experiment show that the main non-enzymatic browning reactions are Maillard and caramelization reaction, and VC or polyphenol does not play an important role in the color formation.

结果显示：美拉德反应和焦糖化是主要的非酶褐变反应，VC、多酚类物质对颜色形成不起主要的贡献作用；果糖和蔗糖在非酶褐变反应中起重要的作用，葡萄糖的作用几乎可忽略不计。

In the first way, the other five medicines except Radix sophorae flavescentis against NDV was better. In the second way, the effect of Herba houttuyniae, Patrinia villosa juss, Rhizoma polygoni cuspidati and Radix isatidis to NDV was better, but Radix sophorae flavescentis and Folium isatidis had little effect. In the third way, Radix isatidis, Herba houttuyniae, Patrinia villosa juss were more effective than Folium isatidis, Rhizoma polygoni cuspidate. In short, the effects of Radix isatidis, Patrinia villosa juss and Herba houttuyniae on NDV were higher.The first of three more satisfactory complex composites obtained from the experiment was Folium isatidis, Herba houttuyniae, Rhizoma polygoni cuspidati, Patrinia villosa juss and Radix sophorae flavescentis.

在第一种加药方式中：只有苦参没有产生作用，其余五种药物抗NDV的作用均较强；在第二种加药方式中：鱼腥草、败酱草、虎杖、板蓝根效果较好，而苦参及大青叶则几乎不起作用；在第三种加药方式中：板蓝根、鱼腥草、败酱草有较强的作用，大青叶、虎杖次之，由以上结果可以看出在三种方式中，板蓝根、败酱草和鱼腥草抗NDV的作用较强。

There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.

人及哺乳动物体内有四种结构及药理学性质略有差异的异物体，分别为ET-1、ET-2、ET-3、ET-β，而在人主要是ET-1，在生理条件下，ET-1在血浆中含量较低，约为5ng〓，故ET-1不是一个循环激素，而是局部合成释放，局部起作用的活性物质，半衰期约1小时，ET-1是目前已知的最强的血管收缩剂，对静脉的作用比动脉强，在血管床，ET受体有A、B两型，A型主要分布在平滑肌细胞，B型主要分布在内皮细胞，它可以通过旁分泌途径刺激内膜增生，具有有丝分裂原效应，可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩，使静止期SMC进入增殖期，还可以通过信号传导途径，与bFGF、GTF-β、PDGF等生长因子协同作用，起共有丝分裂原作用。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
