甲公司于1995年获得国家专利局颁发的9518号实用新型专利权证书，后因未及时缴纳年费被国家专利局公告终止其专利权。1999年3月甲公司提出恢复其专利权的申请，国家知识产权局专利局于同年4月作出恢复其专利的决定。2000年3月，甲公司以专利侵权为由对乙公司提起民事诉讼。诉讼过程中，乙公司向专利复审委员会提出请求，要求宣告9518号专利权无效。2001年3月1日，专利复审委员会作出维持该专利有效的审查决定并通知乙公司。

1992年9月4日修正的《专利法》对专利权的恢复未作出任何规定，假设被告在诉讼中提出“恢复专利权的行为属于合法的自由裁量行为”，你认为是否成立为什么( )。

A．被告在诉讼中提出“恢复专利权的行为属于合法的自由裁量行为”的观点不成立

B．按照依法行政原则中职权法定的要求，行政行为必须有明确的法律授权

C．由于法律对被告没有恢复专利权的授权，所以其行为不属于合法的行政自由裁量行为

D．被告在诉讼中提出“恢复专利权的行为属于合法的自由裁量行为”的观点成立

     The first thing that man invented for sports was the ball.

     In ancient Egypt, everywhere, throwing stones was the game that children loved most. But it was bad

to hurt a child throwing a rock. While looking for something less dangerous to throw, the Egyptians made

the first ball.

     At first, balls were made of grass of leaves held together by vines  (藤条). Later they were made of

pieces of animal skin sewed together and filled with feathers.

    Even though the Egyptians were warlike, they found time for peaceful games, each with its own set of

计算题

为了节约林木资源，近几年兴起石头纸．石头纸可用沿海水产养殖中产生的大量废弃贝壳制得．为了测定某种贝壳中碳酸钙的质量分数，取贝壳15克，加入150克7.3%的盐酸溶液，充分反应后，称得剩余物质的总质量为159.72克．（假设贝壳中其它物质不与盐酸反应）有人认为，根据上述实验数据，可按如下方案计算：根据“150克7.3%的盐酸溶液”，得出参加反应的氯化氢质量，然后根据反应原理求得碳酸钙的质量，最后求出贝壳中碳酸钙的质量分数．

（1）以上方案是否正确？　                                          　．

（2）计算贝壳中碳酸钙的质量分数．
