1. In the field of information security, CPK is the abbreviation of "combined public key", which is called combined public key in Chinese. It is an encryption algorithm, which can generate large-scale keys with very few resources.

2. CPK (creatine phosphokinase) generally refers to creatine kinase, which is higher in skeletal muscle, myocardium and smooth muscle, followed by brain tissue, gastrointestinal tract, lung and kidney.

3、? CPK (process capability index) generally refers to the process capability index, which refers to the degree to which the process capability meets the requirements of product quality standards (specification scope, etc.). ), also known as the post process capability index, refers to the actual processing capability of the process in a controlled state (stable state) within a certain period of time.

Extended data

There is a great relationship between process capability index and process capability index. The greater the value of process capability index, the smaller the allowable range of product dispersed phase for technical standards, so the higher the process capability. The smaller the value of process capability index, the larger the relative tolerance range of product deviation, so the lower the process capability.

Therefore, the capability can be judged from the numerical value of the process capability index. From the requirements of economy and quality, the value of process capability index is not the bigger the better, but should be taken in a suitable range.

The study of process capability is to confirm the degree to which these characteristics conform to the specifications, so as to ensure that the unqualified rate of finished products is above the required level and serve as the basis for continuous process improvement. When the measuring system passes Gager &; After the R test, you can start the test of Cpk value.
