The several accuracies of a part include the accuracy of scale, shape, and appearance relative to each other's position.

常常查验的是尺度、圆柱度、圆度、平面度、直线度、同轴度、平行度、笔直度、跳动等项目。依据维修特点，有时不是寻求单个零件的几许尺度，而是要求相对合作精度。

The items often checked are scale, cylindricity, roundness, flatness, straightness, coaxiality, parallelism, straightness, and runout. According to the maintenance characteristics, sometimes it is not seeking a few scales of individual parts, but rather requiring relative cooperation accuracy.

零件的外表质量包含外表粗糙度，外表有无擦伤、腐蚀、裂纹、剥落、烧损、拉毛等缺点。

The appearance quality of the parts includes surface roughness, whether there are defects such as scratches, corrosion, cracks, peeling, burning, and burrs on the surface.

零件的物理力学功能 除硬度、硬化层深度外，对零件制作和修正过程中构成的功能，如应力状况、平衡状况、弹性、刚度、振动等也需依据‘状况恰当进行检测。

The physical and mechanical functions of parts, in addition to hardness and depth of the hardened layer, also require appropriate testing of the functions formed during the production and correction process of parts, such as stress status, balance status, elasticity, stiffness, vibration, etc., based on the condition.

零件的荫蔽缺点 包含制作过程中的内部夹渣、气孔、疏松、空泛、焊缝等缺点，还有运用过程中发生的微观裂纹。

The shading defects of the parts include internal slag inclusion, porosity, looseness, hollowing, and welding seams during the manufacturing process, as well as micro cracks that occur during the application process.

零部件的质量和静动平衡 如活塞、连杆组之间的质量差，曲轴、风扇、轴、车轮等高速转动的零部件的静动平衡。

The quality and static and dynamic balance of components, such as the quality difference between pistons and connecting rod groups, and the static and dynamic balance of high-speed rotating components such as crankshafts, fans, shafts, and wheels.

零件的资料性质如零件合金成分、渗碳层台碳量、各部分资料的均匀性、中石墨的拆出、橡胶资料的老化变质程度等。

The data properties of the parts, such as alloy composition, carbon content of the carburized layer, uniformity of each part of the data, removal of graphite, aging and deterioration degree of rubber data, etc.

零件表层资料与基体的结合强度 如电镀层、喷涂层、堆焊层和基体金属的结合强度，机械固定联合件的联合强度，轴承合金和轴承座的结合强度等。

The bonding strength between the surface data of the parts and the substrate, such as the bonding strength between the electroplating layer, spraying layer, surfacing layer, and substrate metal, the bonding strength of mechanical fixed joint components, the bonding strength of bearing alloy and bearing seat, etc.

组件的合作状况 如组件的同轴度、平行度、啮合状况与合作的严密性等。

The cooperation status of components, such as coaxiality, parallelism, meshing status, and tightness of cooperation.
