比立

结果表明：球磨加工的矿渣粉比立磨加工的矿渣粉颗粒尺寸分布宽、圆形度高；

The result shows that slag powder by ball mill has wider particle size distribution and higher circularity than that by vertical mill ;

在矿渣粉比表面积相近（约430m~2/kg）时，球磨矿渣水泥的强度比立磨矿渣水泥的强度高。

And that the strength of slag cement by ball mill is higher than that by vertical mill when the specific surface area of slag powder are similar ( about 430 m ~ 2 / kg ) .

制定一个实际些的目标难道不是更好吗？制定一个我们能确保完成的目标，比如说穿上近期买的牛仔裤能够刚好合身，会比立誓在短短几个月减去五十磅（即二十三公斤）好很多吧。

Isn 't it better to be realistic , and set goals that we can be reasonably sure of accomplishing , such as being able to fit into those mom jeans that we bought recently , rather than vowing to lose 50 pounds ( 23 kilograms ) in a few months ?
