Twelve portions of samples above mentioned were added into 50mL colorimetric tubes, 10.0g of each sample was weighed. Then they were divided into 6 groups. The final series of concentrations of the samples were 0, 5.0, 10.0,20.0, 50.0, and 100.0 mg kg-1(2 parallel per sample). At the same time, the same method above was also employed with S. The results for the determination of O in these samples were listed in Table 1. From Table 1 we concluded that a good agreement between U and S when the content of sample was below 20.0 mg kg-1, however, the results of U were superior to those of S when the contents were above 20.0 mg kg-1. 分別取10.00g 上述樣品12份，分6組加入到50mL比色管中，加入O標(biāo)準(zhǔn)溶液使測(cè)定的O濃度分別為0、5.0、10.0、20.0、50.0、100.0mg/kg（每組2份平行）；同樣取10.00g 上述樣品12份，分6組采用S方法提取，加標(biāo)方法同U方法。 兩種方法比對(duì)數(shù)據(jù)見表1。測(cè)定結(jié)果表明，當(dāng)測(cè)定結(jié)果≤20.0mg/kg時(shí)，兩種提取方法均能滿足分析要求，無明顯差異；當(dāng)測(cè)定結(jié)果＞20.0mg/kg時(shí)，U方法測(cè)定的結(jié)果優(yōu)于S方法。 |

請(qǐng)樓上的朋友幫忙修改，下面是詳細(xì)的內(nèi)容，需要修改的是英語，中文僅供參考，深表感謝！ Twelve portions of simulation soil standard samples above mentioned were added into 50mL colorimetric tubes, 5.0000g of each sample was weighed. Then they were divided into 6 groups. The final series of concentrations of the simulation soil standard samples were 0, 5.0, 10.0, 25.0, 50.0, and 100.0 mg kg-1(2 parallel per sample). At the same time, the same method above was also employed with Soxhlet extraction. The results for the determination of petroleum oils in these simulation soil standard samples were listed in Table 1. From Table 1 we concluded that a good agreement between ultrasonic solvent extraction and Soxhlet extraction when the content of simulation soil standard sample was below 25.0 mg kg-1, however, the results of ultrasonic solvent extraction were superior to those of Soxhlet extraction when the contents were above 25.0 mg kg-1. 取上述模擬標(biāo)準(zhǔn)土壤樣品5.00g 共12份，分成6組分別加入到50mL比色管中。然后加入石油類標(biāo)準(zhǔn)溶液，使測(cè)定的模擬標(biāo)準(zhǔn)土壤樣品中石油類濃度分別為0、5.0、10.0、25.0、50.0、100.0mg/kg（每組做2份平行）；另取同樣的質(zhì)量和分?jǐn)?shù)的樣品，分成6組采用索氏提取法，加標(biāo)方法與超聲波萃取法相同。兩種方法比對(duì)數(shù)據(jù)見表1。測(cè)定結(jié)果表明，當(dāng)測(cè)定結(jié)果≤25mg/kg時(shí)，兩種提取方法均能滿足分析要求，無明顯差異；當(dāng)測(cè)定結(jié)果＞25mg/kg時(shí)，超聲波萃取法測(cè)定的結(jié)果優(yōu)于索氏提取法。 |

| Add 5.0000g each simulation soil standard sample mentioned above and petroleum oil standard solutions into 50mL colorimetric tubes to make final simulation soil standard samples with concentrations of 0, 5.0, 10.0, 25.0, 50.0, and 100.0 mg.kg-1(2 parallel samples per concentration). The final simulation soil standard samples were then treated with ultrasonic solvent extraction and Soxhlet extraction and petroleum oils in these simulation soil standard samples were determined thereafter. The results of petroleum oils in these simulation soil standard samples were listed in Table 1 and it can be concluded that similar extraction effects can be achieved through both ultrasonic solvent extraction and Soxhlet extraction methods when the concentrations of simulation soil standard sample was below 25.0 mg.kg-1 while the extraction effects of ultrasonic solvent extraction were better than those of Soxhlet extraction when the concentrations were above 25.0 mg kg-1.即使你改過的中文還是讓人不太明白！怎么加樣量又成5g了？你到底怎么做的？以上翻譯是按我理解弄的，你看看是否符合本來面貌。有問題再說吧 |
