9.The temperature distributions of the flow field measured by two-platinum lawrencium thermocouple certify that the heating scheme by counter flow mixi...
10.This method was applied to the determination of a ferroniobium certified reference material and the results compare favourably with the certified values.
11.Based on the new method, a criterion of determining overconstrained mechanisms was presented and a new four-loop planar overconstrained mechanism was certified.
12.Certified reference material of the high-purity silicasol was prepared by removing impurity ions from the high purity silicasol according to the ion exchange resin.
