4、厚度表示方法 Representation method of thickness
薄膜厚度的標稱值用薄膜厚度中心值（整數(shù)值，如 3、7、10、15…）加尾數(shù)（小數(shù)點后一位）或其代碼表示。本公司 MPP 膜厚度標稱值為重量法厚度（WMV）；RPP/RRPP 膜厚度的標稱值為機械法厚度（MMV）(十層法)。
The nominal value of the film thickness is indicated by the central value (integer value, such as 3, 7, 10, 15.) of film thickness plus mantissa (one point after decimal point) or its code. Our nominal value for MPP film thickness refers to WMV, the nominal value for RPP/RRPP film thickness refers to MMV( ten layer method ).
