Standard practice for determining the consistency of refractory castable using the ball - in - hand test 通过手中球试验测定耐火浆料坚实度的标准实施规程
Precast concrete products - test method for glass - fibre reinforced cement - measuring the consistency of the matrix - ' slump test ' method 预制混凝土制品.玻璃纤维增强水泥的试验方法.基质坚实度的测量. "坍塌"试验方法
The dominant frequency increased as increase of the pear firmness , and decreased as increase of the pear mass 经分析,主响应频率随坚实度的增加而变大、随质量的增加而变小,主响应频率与质量、坚实度有较好的相关性。
As a result of the analysis , the dominant frequency was significantly affected by the pear firmness and mass , while the excitation point , detected point , excitation intensity and impacting material did not 结果表明,不同测点、材料、激励点和速度对响应主频率没有较大影响,而质量、坚实度的影响则显著。
