The results indicate that the synthesized xerogel was mesoporous material. The mean diameter of pores and the largest specific surface area of the xerogel were 3nm and 901 m^2g^(-1), respectively.

测试结果表明：合成的硅基干凝胶为平均孔径3nm左右、最大比表面积901平方公尺g^(-1)的介孔结构。

At present the two systems has passed the 72 h test as the output of the No.1 mill is 164 t/h and that of the No.2 is 160t/h, the specific surface of the product is 320-330 m^2/kg and the temperature of the cement coming out of the mill is 70℃, all of which reached or exceed the design index.

这两套水泥磨粉磨系统目前均已顺利通过72h的性能考核测试，其中：平均台时产量分别为164t/h（1磨）和160t/h（2磨）；比表面积为320-330平方公尺/kg；出磨水泥温度约70℃，均达到并超过设计指标。
