There are five courses we can conclude from the investigation. Firstly, the dissemination for gymnastics is infirm. Secondly, gymnastics was deleted from the national physical exercise standard in 1982. Thirdly, neither teachers nor students want anybody to be injured. Fourthly, the only children's risk consciousness are decreasing day by day. Fifthly, parts of teachers disregard that the request of gymnastics has been changed and just follow rules docilely.

湖北省高校体育院系体育教育专业本科体操普修课教学中的主要劣势是教学质量的滑坡，其成因主要有：国家与高校体育院系对体操的宣传力度不够；1982年国家锻炼标准中除去体操内容；体操教师及学生求平安思想；独生子女冒险意识减弱；部分教师不顾社会对体操需求发生变化的事实，存在着"以不变应万变"的思想。

The technology of water washing can remove all above-mentioned harmful impurities except of P〓O〓 in crystal lattice. However, the feasibility of water washing technology may rely on the ability in investment as the initially required investment size is big. Also, this technology may cause a secondary pollution as the process generates large amount of waste water. Organic matters can be removed by a floating technology. Lime may be used as a neutralizing agent which transforms watersoluble P〓O〓, F〓 into salts of low solubility. Grinding can improve the crystal morphology and the gradings of PG. A combined technology of neutralization with grinding may have the advantages of both.

水洗可除去除共晶P〓O〓以外的所有杂质，但存在一次性投资大、工艺复杂、污水排放造成二次污染等问题；浮选可除去磷石膏中的有机物；石灰中和使有害态的可溶磷、氟转化为惰性的难溶盐；适当的球磨可有效改善磷石膏的颗粒形貌与级配；筛分可除去有害杂质含量特别高的部分，提高磷石膏品质；球磨与石灰中和结合的预处理工艺，既消除了主要有害杂质的影响，又改善了磷石膏颗粒结构与级配。
