Impervious surface is a character of urban areas. The ratio of imperviousness and total area becomes a significant urban ecological index in the research of urban hydrology, water pollution, urban vegetation mapping and so on.

不透水面是城市地区的典型特征，它与城市总用地面积的比值--不透水率作为一个重要的城市生态指数常出现于城市水文、水质、面源污染以及城市植被制图等研究中。

Scientists have attached importance to the imperviousness, an integrated watershed health indicator, and this article make an introduction together with a brief comment on it.

不透水地面作为流域健康状况的综合指示因子，已经受到国际上普遍重视。本文对国际上不透水地面的研究做了简要评述。

A lab test apparatus was developed into evaluating the noise reduction of the porous cement concrete. A constant head permeameter was developed to ascertain the water permeability of porous cement concrete, the influence of the porosity and pore size on the water permeability was studied.

另外，对多孔水泥混凝土的透水性能进行了研究，通过建立有效孔隙率、孔径大小与渗透系数的关系，结合其实际透水性能，得出了满足一般排水性路面排水要求的有效孔隙率范围和级配。

Pervious concrete is of good perviousness,it can release the problems of highway seeper and urban environment,so it is a sort of environmental protection concrete. Through comparison test of performance of mixtures with different single particle size,the result indicates that mixing single particle size mixtures is of a good many advantages.

透水混凝土具有良好的透水性，能够缓解公路积水和城市环境问题，是一种环保型的混凝土，通过对不同单粒径混合料的性能进行比较试验，结果表明，将单粒径混合料进行混合具有很多优点。

The experiment used Four kinds of farmland common herbicides (Fenoxaprop、Clethodim、Glyphosate、Fenoxaprop-p-ethl),MDA content、Leaf cell menbrane permeability、Chlorophyll content were tested under three treaments of different medicaments and combined with the growth index.The results showed:(1) When they were used in normal concentration,growth and the others physiological indexes had obviously different under four kinds of herbicides treatments.According to effects of four herbicides on Zanthoxylum bungeanum Maxim ,the effect of Glyphosate randed first,the rest ones were Clethodim、Fenoxaprop-p-ethl and Fenoxaprop.

以农田中常用的6.9%骠马水乳剂、24%收乐通乳油、88.8%飞达红水溶性粒剂、6.9%威霸水乳剂等四种除草剂为供试对象，通过对各药剂的三种浓度处理下花椒叶片中丙二醛含量、叶片中叶绿素含量、叶片中细胞膜通透性的测定，再结合生长量指标进行分析研究，结果表明：(1)在常用浓度下，四种除草剂对花椒生长量及各生理指标的影响有很大差异，飞达红影响最大，依次为收乐通、威霸、骠马。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.
