Accordingly, in an attempt to stabilize the water current, to make fish migration easy, and to help shrimp to crawl over the check dams to upstream to breed, it is considered to add a porosity filtering on the main body of fishway (hereuinafter referred as improved fish-bone-type fishway).

但水流在鱼骨型鱼道中流况非常紊乱，故考虑在鱼骨型鱼道之主要支干上加一多孔隙滤材(本文称改良后鱼骨型鱼道)，使水流较趋於稳定，水中鱼类更易於上溯外，更让虾类藉以攀爬至防砂坝上游繁殖。

In the aspect of shrimp migration test, the finding reports that shrimp would use the porosity filtering to crawl towards upstream when the flow rate is at 0.001cms, and do so on the bottom of the fishway when the flow is even less.

试验结果显示，在水理试验方面，改良后鱼骨型鱼道水位皆比原鱼骨型鱼道高，流量则比原鱼骨型鱼道低，显示多孔隙滤材能有效改善流况；排砂试验方面，泥砂约於时间第30分钟即达到输砂平衡，排砂率在97％以上，残留於鱼道之泥砂为3％以下，证明增设多孔隙滤材并不影响其排砂率；鱼类上溯试验方面，粗首鱲於试验时间内，上溯率达73％以上，皆比原鱼骨型鱼道为高，显示改良后鱼骨型鱼道更适於鱼类上溯；而溪虾上溯试验方面，发现溪虾於流量0.001时，藉由多孔隙滤材向鱼道上游攀爬，再由量更小的情况下，溪虾便由鱼道渠底向上游攀爬。

During treatment of soft soil subgrade located in large regional fault zone, model of floating bridge above water is adopted. Based on characteristics of subgrade soil with large porosity and loose, consolidation grouting method is used to raise load capacity of subgrade which can combine underground reinforced concrete raft foundation with steel pipe friction micropile to improve integrity strength of special heavy traffic soil subgrade.

摘要］ 阐述在区域性大型断层带的软基处理中运用"水上浮桥"的建模思维方式，根据路基岩土体孔隙率大、松散的特点，采用固结灌浆从挖掘岩土体本身的潜力提高地基承载力，固结灌浆岩土体使准连续配筋混凝土地下筏板基础与摩擦型钢管微桩有机结合，以此提高运煤特重交通路基的整体强度。

Regular porosity in about 38 nanometer size was observed using atomic force microscopy. Excitation and Emission spectrum were obtained by using F-4500 fluorometer.

用F-4500型荧光分光光度计测量其三维荧光谱，与未经氧化的铝片作对比，发现前者的激发谱在280 nm~340 nm有一个较宽的谱带，并且在253.8 nm附近有一个肩峰，发射谱有一个以417.4 nm为峰值的较宽谱带，而后者却无任何明显的发射峰和激发峰。
