片剂硬度过小会引起（）
A．裂片
B．松片
C．黏冲
D．色斑
E．片重差异超限
参考答案：B
解析：
本题考察片剂压片过程中易出现的问题及其原因。裂片是由于压力分布不均、粘合剂选择不当或用量不足、细粉过多、压力过大和冲头与模圈不符造成。松片是由于压力大小不当造成。颗粒不够干燥或药物易引湿，这可造成粘冲，片剂硬度过小会引起松片颗粒粗细相差悬殊或颗粒流动性差时会产生色斑。颗粒粗细不均匀、颗粒流动性差、下冲升降不灵活、加料斗装量时多时少都可造成片重差异超量。故答案选C、B、E、D。

At one point along an open highway, I __5__ a crossroad with a traffic light.I was alone on the road by now, but as I __6__ the light, it turned red and I braked to a stop.I looked left, right and behind me. Nothing.Not a car, no suggestion of headlights, but there I sat, waiting for the light to __7__, the only human being for at least a mile in any __8__. I started __9__ why I refused to run the light.I was not afraid of being __10_, because there was obviously no policeman around, and there certainly would have been no __11__ in going through it. Much later that night, after I __12_ a group of my friends in Lewisburg and climbed into bed near midnight, the question of why I'd stopped for that light __13__ me, I think I stopped because it's part of a contract (合同) we all have with each other.It's not only the __14__, but it's an arrangement we have, and we trust each other to __15__ it: we don't go through red lights.Like most of us, I'm more likely to be __16_ from doing something bad by the social convention that __17_ it than by any law against it. It's amazing that we ever __18__ each other to do the right thing, isn't it? And we do, too.Trust is our __19__ preference. I was so __20__ of myself for stopping for the red light that night. | ||||
