Laser digitizing measurement has been applicated in reverse engineering widely for its high measure speed and extensive applicable area.

激光数字化测量因其测量速度快，适应范围广，在反求工程中获得了越来越广泛的应用。

The only way of enlarging the applicable area is to study and produce new cooling material of constant temperature with high quality coefficient.

扩大应用范围的唯一途径是研究新型高优质系数的常温致冷材料。

This paper researches the different testing methods of soil resilient modulus, and primarily evaluates their merits and shortcomings, applicable area and mend measure.

本文通过对不同土基回弹模量测试方法的研究，初步评价了其优缺点、适用范围及改进措施。
