【正文】 observed. With increasing ER, the lower temperature peak was found to shift to higher temperature. The corresponding shift in the higher temperature peak was much less. It is shown that these peaks originate in the melting of crystalline species having different degrees of crystal disorder and stereoblock character. 此例回答了如下四個問題：回答做了什么? （研究工作范圍） ——用DSC 研究聚丙烯的熔融行為回答怎樣做的? （實驗要點）——固體拉伸取向回答結(jié)果如何? （主要結(jié)論）——兩個熔融峰及其隨拉伸比的變化回答原因何在? （結(jié)果的解釋,結(jié)論）——存在不同晶體6 常用句式（1）研究范圍（to be）carried out / performed / made / conducted(to be) studied / investigated(to be) described / deal with / elucidated / given / presented / developed / employed / derived / prepared / synthesized / monitored / determined / measured / observed / recorded / examined / characterized / identified / tested / calculated / proposed / used to study / used to establish / evaluated / discussed(2) 實驗要點（to be） prepared by the reaction of … with …synthesized via reacting obtained via condensationby means of / by using / by the use of / using … as …over a wide range of … / over a broad position range / over most of the range of …/ over the entire … range / covered the ranges from … to … / in the range of … / in the temperature range from … to … / with a variety of … contents /containing … percent or more … / in the presence of …/ in the absence of …（3）主要結(jié)論用That 從句或由It 引起的that 從句表示實驗結(jié)果：The results indicated that … / The results show that … / The results demonstrated that … / The results reveal that …It was shown that …It can be seen that …It was found that …It was discovered that …It was concluded that …It has been demonstrated that …It was clarified that … It was revealed that …It is considered that …It was confirmed that …It is suggested that …It was supposed that …It has bee apparent that …以… to be 后的表語成分表示測定、計算等的結(jié)果The rate constant of the catalytic reaction was calculated to be cm3 mol1s1.The theoretical equation was proved to be correct by the experimental results.表示具有某種影響，以及數(shù)量的依賴、增減關(guān)系… 與 … 有關(guān)… （to be）correlated with …associated with …related to …dependent upon …independent of …in relation to …in a linear relationship with …proportional to …inversely proportional to …… depends on …The dependence of … on …… increase with the increase of …… decrease with the increase of …（不）相符的表示方法… (to be) in good agreement with… (to be) found to agree well with …… (to be) consistent with …… (to be) essentially identical with …… (to be) found to coincide essentially with …… (to be) closely
