You can choose the big ball or smaller ball, the biger ball need more point. you must get to more then 100 point you can get the next level.

你可以选择使用球体的大小，越大消耗的分数越多，只有超过100分才能过关。

The results showed that the austenite recrystallization occurs in a temperature range biger than thenormal quenching temperature and there is an optimum temperature range for the grain refining.

结果表明，奥氏体的再结晶发生在钢的正常淬火温度以上的一个温度范围，并在该范围内存在晶粒细化效果最佳的温度区域；

The results of study also shown that the biger difference of refractivity between two kinds of materials, the wider of the bandgap for two electromagnetic modes, and easier to produce full bandgap.

另外，研究结果表明组成光子晶体的两种材料的折射率差别越大，两种电磁模的禁带越宽，越容易产生完全光子禁带。
