5、10.830.860.920.969.檢驗(yàn)新方法是否可行，即檢驗(yàn)新方法是否有系統(tǒng)誤差，這里采用秩和檢驗(yàn)。求出各數(shù)據(jù)的秩，如下表所示：n=9,n2=9,n=18R1=156.591112141518=91.5R2=79.5對于a=0.05,查臨界值表得：T1=66,T2=102。則,<#0,故新方法與舊方法的數(shù)據(jù)無顯著性差異,即新方法與舊方法的數(shù)據(jù)無顯著差異，即新方法無系統(tǒng)誤差。10.格拉布斯檢驗(yàn)法：、檢驗(yàn)62.2計(jì)算包括62.2在內(nèi)的平均值為69.947,即標(biāo)準(zhǔn)差2.7853,查表得G(0.05,10)=2.176所以G(0.05,10)s=6.06則|dp|=|Xp69.947|=7.

6、747>6.06,故62.2這個(gè)值應(yīng)被剔除。(2)、檢驗(yàn)69.49用同樣的方法檢驗(yàn)得，應(yīng)被剔除。(3)、檢驗(yàn)70.370.3不應(yīng)被剔除。第二章1.Re|2.3.入8.308.258.208.158.108.058.006.16.0,5.9-5.8-5.7_5.6-5.5一5.4-5.3-5.202468發(fā)酵時(shí)間/dpn值殘?zhí)橇?(g/l)pg/(量糖殘42086422221111o186._吸附量(mg/g)DA-201NKA-9AB-8D-4006D-101S-8NKA-H)9m1量壞吸樹脂型號5.6.比例/%/通用格式/通用格式 橡膠工業(yè) 合成表面活性劑 潤滑油（脂） 肥皂及洗滌劑
