Cement-based piezoelectric composite, has been widely used as a kind of smart material in structural health monitoring and active vibration control. However, transient dynamic loads such as impact loads may cause serious damage to the composite. Considering the electrode layer effect, this paper aimed to investigate the theoretical response of a 2-2(More)
As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent(More)
Cement-based piezoelectric materials are widely used due to the fact that compared with common smart materials, they overcome the defects of structure-incompatibility and frequency inconsistency with a concrete structure. However, the present understanding of the mechanical behavior of cement-based piezoelectric smart materials under impact load is still(More)
Hawthorn (Crataegus oxyacantha), which is wildly distributed in northern China, has a long history as a medicinal substance, for the treatment of digestive ailments, dyspnea, kidney stones and cardiovascular disorders, etc. Today, it is currently used for the juice production and is used as the raw material for hawthorn wine and vinegar production. However,(More)
