加油!有志者事竟成答卷时应注意事项1、拿到试卷,要认真仔细的先填好自己的考生信息。

2、拿到试卷不要提笔就写,先大致的浏览一遍,有多少大题,每个大题里有几个小题,有什么题型,哪些容易,哪些难,做到心里有底;3、审题,每个题目都要多读几遍,不仅要读大题,还要读小题,不放过每一个字,遇到暂时弄不懂题意的题目,手指点读,多读几遍题目,就能理解题意了;容易混乱的地方也应该多读几遍,比如从小到大,从左到右这样的题;4、每个题目做完了以后,把自己的手从试卷上完全移开,好好的看看有没有被自己的手臂挡住而遗漏的题;试卷第1页和第2页上下衔接的地方一定要注意,仔细看看有没有遗漏的小题;5、中途遇到真的解决不了的难题,注意安排好时间,先把后面会做的做完,再来重新读题,结合平时课堂上所学的知识,解答难题;一定要镇定,不能因此慌了手脚,影响下面的答题;6、卷面要清洁,字迹要清工整,非常重要;7、做完的试卷要检查,这样可以发现刚才可能留下的错误或是可以检查是否有漏题,检查的时候,用手指点读题目,不要管自己的答案,重新分析题意,所有计算题重新计算,判断题重新判断,填空题重新填空,之后把检查的结果与先前做的结果进行对比分析。

亲爱的小朋友,你们好! 经过两个月的学习,你们一定有不小的收获吧,用你的自信和智慧,认真答题,相信你一定会闯关成功。

7.2.2包装袋的清洗将制备好的包装袋表面的污物先用毛刷、去污剂进行清洗,然后再用10mL 丙酮、10mL 四氯化碳、20mL 乙醇清洗,最后用清水淋洗干净,晾干。

干燥完全后称量包装袋质量g 1。

7.2.3测定将98%噻虫嗪原药约80g 加入7.2.2中处理好并称重的包装袋中,封口后,将包装袋置于一配套的小纸桶中,盖好桶盖,将小纸桶置于(54±2)℃的电热鼓风干燥箱中2周。

试验结束后,将被试物倒出,按7.2.2的程序对包装袋进行清洗。

干燥完全后称量包装袋质量g 2。

7.2.4空白样本测定用7.2.1中制备的未接触98%噻虫嗪原药的相同尺寸、相同材质的包装袋样本(对照品),称量样本质量w 1。

然后按7.2.2的程序进行清洗。

干燥后称量样本质量w 2。

7.2.5 计算腐蚀损失率X 按下式计算:式中:X——腐蚀损失率(%);g 1——试验前包装材料样本的质量(g ); g 2——试验后包装材料样本的质量(g ); w 1——清洗前空白样本的质量(g ); w 2——清洗后空白样本的质量(g )。

7.3 试验结果将试验完的样品从包装袋中倒出,清洗包装袋,观察包装袋:第20130507批样品中的包装袋光滑,未见腐蚀斑痕,无明显变化,没有孔蚀,变色等现象。

第20130509批样品中的包装袋光滑,未见腐蚀斑痕,无明显变化,没有孔蚀,变色等现象。

第20130513批样品中的包装袋光滑,未见腐蚀斑痕,无明显变化,没有孔蚀,变色等现象。

表6腐蚀损失率(X)结果8.爆炸性试验日期:2013-11-06试验温度:24.0℃相对湿度:60%8.1 爆炸性筛选(热稳定性测试)试验8.1.1试验方法: GB/T 22232-2008 化学物质的热稳定性测定差示扫描量热法8.1.2试验方法概述在差示扫描量热仪中,将待测样品和参比样品置于相同条件的坩埚中,放置在温度感应台上,在保护气氛下,坩埚和感应平台被密闭与隔热空间内,在升温过程中,待测样品与参比样品会产生不同的焓变化,通过差示扫描量热仪来确定发生焓变的温度,计算焓(热)。

8.1.3仪器和设备DZ 3335差示扫描量热仪(自带数据处理系统)分析天平:AUW120D,灵敏度0.01mg8.1.4试验步骤8.1.4.1基线扫描将称量并记录质量的空样品坩埚和参比坩埚置于温度感应台上,通入保护氮气,流速控制在30mL/min,置换10min,密闭。
