3 　INTRODUCTION 引言

　　本项除课题意义外, 主要涉猎前人研究情况的评述及本研究的目的, 后两者有时分别列出。兹分述如下:

　　3.1 　REVIEW OF PREVIOUS WORK 以往研究评论

　　还有用其它题目的, 例如: REVIEWOFLITER2ATURE(文献评述) , LITERATURE CITED (文献引述) , PRIOR RESEARCH ( 以前的研究) , SOME PAST DESIGNS(过去的某些设计) , BACK -GROU-ND ( 背景材料), 等等。而这些资料引文的重点要放在引述与本文有关的以往研究的结果, 否则会喧宾夺主。句式常有Sb. et al. tested (reported , gave , car2 ried out experiment on .; Sb found (showed .) that ..还有若干不同的其它表达方法, 写在下边: our exper2 iments show that .; The present study was undertaken toidentify ., Date are presented that suggest ., Our results supported .; The distribution has reported by.; Our laboratory has undertaken a reexamination of.; This article (paper) documents .; We trace (evi2 dence) .This model extends .; Our findings demon2 strate .; We reasoned that .; The effect .were evalu2 ated by means of .; The present results add some fur2 ther elements to .A recent study analyzed he effect of aspirin ( ASA) on primaryhemostasis in uremia , measuring bleeding time (BT). ItwasfoundthatthesamedoseofASApro2 longedBTmorein uremicthat incontrol subjects, sug2 gesting platelets were more susceptible to the inhibitory2 of ASA. This might be due to different ASA pharma2 cokinetics and bioavailability that might be influenced by the uremic condition. 新近一项研究分析了乙酰水扬酸对尿毒症第一期出血的影响, 测定了出血的时间。我们发现, 同样剂量的ASA 均可延长出血时间, 而尿毒症受验者比对照受验者要多。这提示尿毒症的血小板对ASA 的抑制更具敏感性。这可能是由于ASA 的药物动力学和生物可用性不同所致。
