The effect of load specimen surface roughness and test deviation amendment on microhardness of aeronautical noble metal (alloy) wires and sheets was studied in this paper.
研究了加载负荷、试样表面粗糙度及测量偏差修正对航空用贵金属（合金）丝材和薄片显微硬度测量的影响。
Under a certain load level, flourescent penetrant is injected into the crack of specimen.
把试件加载至不同的载荷水平后，向裂纹注入荧光渗透剂；
For a given specimen and notch configuration, maximum load is always dependent on the crack length and independent of the material.
对于特定的试样和裂口几何形状，最大荷载与裂纹长度有关，而与材料无关。
