In this research the lime-fly-ash bound macadam was joined with glass fibers in lab tests. 玻璃纤维掺入到二灰碎石基层中,对其强度和刚度进行试验。
After analyzing the results of the above mentioned experiments, a new process etching glass micro-spheres with 248 nm excimer laser was introduced, and successfully carried out in lab experiments. 通过试验摸索出了一种有效的准分子激光刻蚀玻璃材料的工艺方法,成功地在玻璃片上进行了刻蚀试验;
