In this paper,acetanilide,adipic acid and potassium hydrogen phthalate were chosen as additives to advance polyvinyl chloride to crystallize. The effects of compress mold,annealing temperature and time,additive property and loading on the crystallization,microscopicmorphology and mechanical properties of PVC were studied by means of wide angle X-ray diffraction,differential scanning calorimetry,fourier transform infrared spectrophotometer,scanning electron microscopeand tensile test.

The structures, functions and anticoagulant mechanisms of anticoagulation factors ACF I and ACF II from the venom of Agkistrodon acutus have been investigated. Both ACF I and ACF II form a 1:1 complex with activated coagulation factor X in a Calcium ion-dependent fashion which prevents the interaction of FXa with other proteins in the coagulation process, therefore ACF I and ACF II have marked anticoagulant activity.
