[Methods] According to General Rules of Part IV of Chinese Pharmacopoeia, applicability tests were conducted on microbial limit test methods for the above two traditional Chinese medicine preparations by the plate method. [Results] The established methods showed recovery values in the range of 0.5-2.0 for both experimental strains, and the control bacteria could be detected in the experimental group, but not in the negative control group. [Conclusions] The microbial limit test methods were reliable for the two traditional Chinese medicine preparations and could be used for quality control.展开更多

The scanning Hartmann test setup is formed by modifying the Hartmann screen of the conventional Hartmann test setup. With the rotation of the scanning Hartmann screen and the improved hole arrangement, the whole information of the lens to be tested in the full aperture can be obtained. The measurement accuracy of the aberration is improved and the local error of the lens can be got. In the method, no change of the Hartmann screen is needed for measuring the lenses of different aperture sizes. Experimental results of aberration measurements of two lenses are given to verify the usefulness of the setup.展开更多
