Laser confocal scanning microscopy is a new technology combining modern optics and electronics. The unique feature of point light source and point detecting eliminates out-of-focus blur and spots. Therefore, the axial and lateral resolution of the system is superior and 3-D imaging can be realized by scanning point by point of the object profile. Because of its advantages, confocal measurement technology is widely applied in many fields, such as medical treatment, biology, configuration of substances and micro-electronics.

When proceeding pump testing, we collect a good many parameters, and figure out the pump gross head, pump shaft power, NPSH and other parameters. Different units of those parameters are used in different countries, and sometimes the customer asks for the test data of special media. Making a test of every medium of the same pump is not realistic, and the costs will be increase, so we convert the units of the data, and figure out the testing data according to different customer's special requirements. We reduced costs and got good remarks from the corporation through the application of unit conversion technology.

水泵试验时，要采集诸多参数，并且根据这些参数计算出扬程、轴功率、NPSH等数值，不同国家这些参数采用的单位不同，企业必须能够按照客户要求的单位提供试验数据；并且有时客户要求得到水泵在特殊介质下进行试验得出的试验数据，同一台泵在每种介质下都做一遍试验不太现实，而且会提高企业的生产成本，提出将采集的数据进行单位换算，根据不同国家或者客户的特殊要求求出泵的试验数据，在实际应用中节省了试验成本，得到了企业的好评。
