透水的

Considering the difference of runoff characteristics on different underlying surface in the area of plain tidal river network, four kinds of surface is divided,namely, waters paddy field-, dry land and central urbanized area,and suitable method is adopted separately in each surface to simulate runoff process. Xinanjiang Model usually applicable for mountain areas is introduced to river network area, furthermore, the paper researches runoff calculation of central urbanized area, the underlying surface is divided into pervious and imperviousness areas.In perviousness areas, Hoton Infiltration formula and corresponding spatial infiltration rate curve are used to establish the relationship between infiltration rate and soil moisture in order to decide the infiltration. According to practical situation.

In recent years, the forever-lasting Taiwan and green architecture have become a major topic in our country. In order to resolve the runoff of rainwater resource, to prevent the spoliation of ecology and to reduce the effect of heat island, to search for the suitable mix design of the pervious concrete for Taiwan is not a small issue. Pervious concrete pavement is air permeable and water permeable, the soil underneath can be kept wet and rainwater can quickly filter into ground, so the groundwater resources can renew in time. It improves the environment of road pavement and also possesses many other advantages that improve city environment at drainage, sound absorption and skid resistance, and is suitable for the rainy and humid environment in Taiwan area. However, its high air voids results in low strength, the surface layer of highway pavement was seldom used pervious concrete due to heavy traffic loading.

近年来国内以打造永续台湾与绿建筑为未来努力的方向，为解决雨水资源流失、环境生态破坏及热岛效应扩张，研发本土透水混凝土实有其重要性，透水混凝土铺面可以使空气与水自由地有效的渗入，地下土壤可保持湿润，雨水也能够快速渗入地面至地下水，地下水资源或水位能即时更新，它改善道路铺面的环境，其它的优点尚包括具有良好排水、噪音吸附与车辆抗滑能力，适合铺设於台湾多雨多湿之环境，由於透水混凝土孔隙率较高，其强度低於一般混凝土，应用於重交通量公路面层因此受到局限。

The effect of N-phosphoamino acids on plant cells'membrane permeability was investigated by osmotic method. It was found that in all N-phosphoamino acids, only some phosphoryl polar amino acids such as DIPPSer, DIPPThr, DIPPHis, DIPPAsp, DIPPGlu, DIPPAsn and free serine, threonine could increase the water permeability in plant cell membrane. For example, after 20min. treatment by 1. 5mM DIPPSer, the deplasmolysis time of onion cells was shortened 50%.

三、通过透性实验研究了N-磷酰化氨基酸对洋葱、豌豆等植物细胞膜水透性及溶质透性的影响，发现在所有的N-磷酰化氨基酸及自由氨基酸中，仅有部分N-磷酰极性氨基酸和自由的丝、苏氨酸对植物细胞膜上水透性有增强作用，如1.5mM N-磷酰化丝氨酸可使洋葱细胞质壁复原时间缩短一半以上。

Then through combining the experiment data with the existing calculation formula for barrier-discharge, an empirical formula that can be used to calculate local head loss coefficient of pile permeable groins in the non-submerged condition is obtained.

而后利用已有的桩柱透水丁坝阻水流量计算公式结合试验资料，得到了计算单个桩柱透水丁坝在非淹没状态下局部水头损失系数的经验公式，该公式计算值与实测值符合良好，可为透水丁坝水力特性的进一步研究提供参考依据。

It is concluded that no matter what roadbed is in steady seepage or unsteady seepage, it is more avail to drain of roadbed using better penetration materials (such as no-fines concrete etc) than using weak penetration material s.

另外，推导了设置护坡的路基的地下水渗流方程，分析了设置不同护坡时路基中的浸润线高度及其变化，认为无论路基处于稳定渗流还是非稳定渗流，用强透水材料作护坡比弱透水材料作护坡对路基地下水的排出更为有利。
