It is higher demand of slip casting engineering of imperious curtain of municipal refuse landfill , because its coarse grain and higher sweating rate when its concretion and its antacial poor stability of cement cumulates, its difficult to meet the design specification of antiseepage by the onefold cement slip casting.

城市垃圾卫生填埋场对防渗帷幕注浆的要求较高，单纯的水泥注浆，由于水泥颗粒较粗、水泥浆液凝固时的析水率较高、水泥固结体抗酸稳定性较差，很难满足设计对防渗的要求。采用粘土水泥固化浆液相关性能均能满足垃圾填埋场防渗帷幕的要求。

However, at present, the majority of aluminum alloy casting has been applied online degassing and filtering device, casting temperature is still above the concept is not quite complete and correct.

但是，目前，铝合金铸件大部分已应用于在线脱气和过滤装置，铸造温度仍高于这一概念是不够全面和正确的。

That is to say, it is the moment before the sunset, the golden sunrays irradiate upon the Biji Archway from the west, casting its inverted image to the east street. At the same time, the moon has just rises from the east, its silver moonlights reflecting the Jinma Archway, casting the inverted image to the west street. With the movement of the sun and moon, the shadows of the two archways gradually draw closely, finally totally connected.

就是有那么一天，太阳将落未落，金色的余辉从西边照射碧鸡坊，它的倒影投到东面街上；同时，月亮则刚从东方升起，银色的光芒照射金马坊，将它的倒影投到西边街面上；两个牌坊的影子，渐移渐近，最后互相交接。
