炸药质量的好坏,对于爆破效率及其安全是有密切关系的,因此,在爆破以前,应该对炸药的性能进行试验,检查其质量是否符合于规定标准或技术规范。目前在本局尚未拟定炸药的标准检验方法以前,本期所发表的两篇关于炸药的试验方法是可以供各单位有关部门参考的,希望有关单位加以研究并提出意见,以便充实这一检验方法。——编者—— Explosive quality is good or bad, for blasting efficiency and its safety are closely related, therefore, before blasting, the performance of explosives should be tested to check whether the quality of its compliance with the prescribed standards or technical specifications. At present, before this Council has formulated a standard test method for explosives, two test methods for explosives published in this issue can be used for reference by relevant departments of various departments. We hope relevant departments will study and give their opinions so as to enrich this test method. --editor--
