求翻译：C1--游隙符合标准规定的1组，游隙小于2组。C2--游隙符合标准规定的2组，游隙小于0组。C0--游隙符合标准规定的0组，代号中省略，不表示。C3--游隙符合标准规定的3组，游隙大于0组。C4--游隙符合标准规定的4组，游隙大于3组。C5--游隙符合标准规定的5组，游隙大于4组。 轴承内部游隙是指一个轴承圈相对于另一个轴承圈径向移动的总距离（径向内部游隙）或轴向移动的总距离（轴向内部游隙）。工作游隙是指轴承实际运转条件下的游隙。原始游隙是指轴承未安装前的游隙。游隙值根据大小分三组，一组是基本组（或者叫普通组）、小游隙组（C2)、大游隙组(C3、C4）。有专门的CM组（电机专用游隙）。另补充一点日常应用的举例：正常的工作条件下，宜优先选择基本组；大游隙组适用于内、外圈配合过盈量较大、或者内外圈温度差大、深沟球轴承需要承受较大轴向负荷或者需要改善调心性能、或者需要提高轴承极限转速和降低轴承摩擦力矩等场合小游隙组适用于较向高的旋转精度、需要严格控制外壳孔的轴向位移、以及需要减小振动和噪音的场合。测量轴承的游隙时，为得到稳定的测量值，一般对轴承施加规定的测量负荷。因此，所得到的测量值比真正的游隙（称做理论游隙）大，即增加了测量负荷产生的弹性变形量。但对于滚子轴承来说，由于该弹性变形量较小，可以忽略不计。安装前轴承的内部游隙一般用理论游隙表示。是什么意思？

1 group C1--clearance in accordance with the prescribed standards, clearance is less than the 2 groups. C2--comply with the standards of 2 groups of clearance, clearance is less than 0. C0--clearance complies with standard 0 group, omitted from the code, does not mean that. 3 Group C3--clearance in accordance with the prescribed standards, clearance is greater than 0. C4--comply with the standards of 4 groups of clearance, clearance is greater than 3. C5--clearance in accordance with the prescribed standards of 5 group, clearance is greater than 4. Bearing internal clearance is a bearing ring relative to the total distance of another ring-radial moving (radial internal clearance) or axial movement of the total distance (axial internal clearance). Work clearance refers to the bearing clearance under actual operating conditions. Original clearance refers to the bearing without clearance. Clearance values according to the size in three groups, one group is the fundamental group (or normal), small groups of clearance (C2), large groups of clearance (C3, C4). CM Group has special (motor specific clearance). Another supplementary is daily application of for example: normal of work conditions Xia, Yi priority select Basic Group; large tour gap group applies Yu within, and outer ring tie had Ying volume larger, and or inside and outside ring temperature difference large, and deep groove ball bearing need bear larger axis to load or need improve adjustable heart performance, and or need improve bearing limit speed and reduce bearing friction moment, occasions small tour gap group applies Yu more to high of rotating precision, and need strictly control shell hole of axis to displacement, and and need reduces vibration and noise of occasions. When measuring the clearance of the bearing, to get stable measurement values, generally under measuring load imposed on the bearings. Therefore, the resulting measurements than real clearance (called theoretical clearance), which increases the measuring elastic deformation of the load. For roller bearings, however, due to the elastic deformation of small, negligible. Bearing internal clearance before mounting the general theory of clearance.
