OBJECTIVE To study on diversity of quality of Forsythia suspense collected from different regions. METHOD The hundred-seed weight of shucks was analyzed by the method of hundred grain mass. The thousand-seed weight of seeds was analyzed by the method of thousand grain mass. The contents of the active components in shucks and seeds were determined by HPLC.(More)
Bilayer material systems find wide application in Micro ElectroMechanical systems (MEMS)., especially serving the reflective surface roles in optical MEMS. Unlike the bilayer with fully covered additional layer, the stress related deformation of bilayer with patterned additional layer has been rarely studied. In this paper, we present the out-of-plane(More)
OBJECTIVE To sift the main effective factors of active component of Forsythia suspense. METHOD The active component of F. suspense was mensurated by HPLC, and the contents of nutrition in soil was determined by conventional methods. The active component of F. suspense and the nutrition of soil collected from different regions was analyzed by SPSS 11.0 for(More)
In the present paper, the analysis of the content of CP, NDF and ADF in the whole dry hay of oats was carried out by using near infrared reflectance spectroscopy (NIRS) technique, and in combination with the partial least square (PLS) regression algorithm the calibration analysis was performed at the same time. The results showed that the calibration models(More)
