论文研究目的完全可以作为引言的结尾。也可以简单介绍一下文章的结构及每一部分的主要内容，从而起到画龙点睛的作用，使读者了解文章的轮廓和脉络。
至于研究结果，在引言中完全可以不写。研究结果是结论部分最主要的组成部分。例29是引言的结尾，介绍文章的结构。
例29
…Before examining in detail the optimum control strategy for the drivetrain, Section 2 defines the hybrid arrangement under study. A description of the optimization process using an appropriate cost function is then presented in Section 3 followed by a method of translating the resulting control structure into a sub-optimum algorithm capable of being implemented in real time.www.cooyu.net. Using the optimum control structure the effect of component ratings on the vehicle's performance is evaluated in Section 4, while Section 5 discusses the practical implementation of an overall vehicle control algorithm. Finally, in Section 6, an indication of the vehicle's potential for substituting petroleum fuel by electricity is given.
在介绍全文的结构时，要避免使用同一个句型结构，如，Sections l describes…Section2 analyses…Section3 discusses…Section 4 summarizes…这样，每句话用同样的词开头，句型结构显得单调、枯燥乏味。 www.cooyu.net.
