allowed for 什么意思(装催化剂)? 原句: the weight of material rejected during screening must be recorded and allowed for. = the weight of material rejected during screening must be recorded + the weight of material rejected during screening must be allowed for. 后来看到在screening 这部分讲到:筛出的细粉量不得大于1%。(推测可能是从cat购买价和机械强度方面来考虑的)。 因此这里应该应该是楼上各位所言的:并且(筛掉的cat重量)必须在容许范围内。 此帖到此结束,多谢各位。 查看更多
