1·In the first part of the experiment, students will subject an ordinary steel reinforcing rod to a tension test using a testing machine designed specifically for that purpose.

在第一部分，学生要用为此特制的实验仪器对一根普通预应力钢杆做拉力实验。

2·As testified by engineering practice, the reinforcing effect is good. It opens a new approach of the application of small scale anchor rod.

实践考验证明，加固效果良好，为今后小型锚杆的应用开辟了新的途径。
