4、厚度表示方法 Representation method of thickness
薄膜厚度的标称值用薄膜厚度中心值（整数值，如 3、7、10、15…）加尾数（小数点后一位）或其代码表示。本公司 MPP 膜厚度标称值为重量法厚度（WMV）；RPP/RRPP 膜厚度的标称值为机械法厚度（MMV）(十层法)。
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 ).
