However, the flexural strength of UHPC decreases a little as fly ash from incinerator or water-quenched slag from plasma for part replacement of quartz powder increases.

在制作添加10%或15%水淬熔岩或垃圾焚化飞灰之UHPC水沟盖其载重强度均可达到10公吨要求，但水沟盖表面因添加垃圾焚化飞灰而呈现腐蚀现象。

Fly ash from incinerator and water-quenched slag from plasma for part replacement of cement or quartz powder was used as ultra-high performance concrete which might be manufacturing UHPC ditch cover being under discussion.

近年来因经济与工商业的迅速发展，同时衍生出许多问题，一方面是钢铁需求量逐年增加，其钢铁价格不断向上攀升，使得道路上的水沟盖也不断地遭偷窃；另一方面为废弃物处理的问题，预估每年平均会产生200万吨的一般垃圾，其垃圾大部分均使用焚化炉来处理，但经焚化炉处理后仍有许多的焚化灰渣需要掩埋，所以本研究针对以上两大问题，探讨以超高性能混凝土添加水淬熔岩或垃圾焚化飞灰来取代超高性能混凝土中之水泥或石英粉，并制作水沟盖进行相关研究。

Under the plastic-mulched ridge and furrow cultivation, the average soil water content of furrow (12.7%) was significantly higher than that of ridge (9.1%) at the soil depths of 20-100 cm. The locally compacted ridge served as a water flow barrier and a rainfall collection area under locally compacted ridge and furrow cultivation, and the water content of furrow was significantly higher than that of ridge in the same soil depths, which was similar to the characteristic of soil water distribution under plastic-mulched ridge and furrow cultivation. No significant differences were found in soil water content of furrow between locally compacted ridge and furrow cultivation and plastic-mulched ridge and furrow cultivation, with the same efficiency of water collection.

相对于自然垄沟，膜垄的集雨效果明显，沟中土壤平均含水量显著高于垄中，20～100cm土层范围内平均土壤含水量分别为12.7％和9.1％；成垄压实土壤水分在剖面分布状况与盖膜垄沟的水分分布相似，水分向沟内集中，沟中土壤水分含量显著高于同一土层深度处垄中土壤含水量，且与盖膜垄沟处理下沟中土壤水分含量无显著差异，在集水和聚水方面表现出和膜垄的相似性。

To Clean: Inspect or replace worn valve disc, disconnect control pipe and unscrew bonnet from valve body using blunt tool and hammer on bonnet lugs.

清洗：检查或更换磨损的阀门阀瓣，断开控制管道，用钝工具和锤打阀盖塞顶部，从阀体上旋下阀盖。

He also sealed with a valve rod packing case, packing box, including a series of packing rings, gland, or guide cover.

他也用填料盒密封阀芯杆，填料盒包括一系列的填料环、压盖或导向盖。

Bellows Seal Valve Cover: Use the bellows to prevent leakage around the closure element connecting rod of a valve cover.

波纹管密封型阀盖：使用波纹管来防止截流元件连接杆周围泄漏的一种阀盖。

The seal test Test the stem and the valve cover seal sealing performance of the test, Deputy Shell Test Such as the valve body and valve cover is made of the valve housing connected to the pressure test.

上密封试验检验阀杆与阀盖密封副密封性能的试验壳体试验对阀体和阀盖等联结而成的整个阀门外壳进行的压力试验。

The trap body and cover shall be manufactured out of cast iron, the diaphragm cover shall be forged brass, the diaphragm shall be duplex phosphor bronze type with stainless valve cone, the condensate valve and seats shall be hardened stainless steel and the float shall be manufactured out of seamless copper.

这种疏水阀的阀体和阀盖应该采用铸铁制造，隔膜盖应该采用锻造黄铜，这种隔膜应该是双磷青铜类型并配置不锈钢阀芯，凝结水阀和阀座应该采用硬化不锈钢，浮子应该采用无缝铜制造。

The airfoil (18) includes a tip cap (32) extending between the pressure (20) and suction (22) sidewalls; and spaced-apart suction-side (34) and pressure-side tip (36) walls extending radially outward from the tip cap (32) to define a tip cavity (38) therebetween.

在压力侧壁(20)和抽吸侧壁(22)之间延伸着一个顶端盖(32)，从该顶端盖(32)沿径向向外延伸着互相间隔开的抽吸侧顶端壁(36)和压力侧顶端壁(34)，在它们之间形成一个顶端凹腔(38)。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
