In this note, we shall give the direct product decomposition of a molecular lattice using the concepts of molecules, then we shall discuss the structure of a generalized order homomorphism. About the concepts and notations in this note, refer to [1—7]. L(M) denotes a molecular lattice (i. e. a completely distributive lattice) with M as the set of molecules in L. Let {L_i:i∈I} be a family of mo- 展开更多

F is a U(m)-invariant polynomial of degree k【m definod on the Lie algebra u(m), F(Ω) is a characteristic form of M defined by F. Let σ be arbitrary closed (2m—2k)-form M.

It has negative feedback actions to the secretion of pituitary follicle stimulating hormone (FSH). In 1976, DeJong et al. demonstrated that bovine follicular fluid showed inhibin activity. This aroused great interest in inhibin, study. Since then, inhibin has been purified from rete testis fluid of human, ovine, rat and follicular fluid of human, bovine, ovine and pig. It has been gradually learnt that it has 展开更多

INTRODUCTIONThough advances in Li battery research have been made in recent years, people still pay enough attention to high energy density battery, and also develop ultra-thin Li battery at the same time. This kind of battery finds wide use in cards such as the ID, IC, credit, radiation, radio, computer as well as all card-shaped instrument. 展开更多
