orbit of tea-processing arm has been obtained, and the difference orbit of the different processing procedure has been compared. Length parameter of each member hasobtained, L_(OA) = 50 ～ 115mm, L_(OB) = 200 mm, L_(BC)= 645 mm.
The Influence of 《P--Delta》Effect on Nonlinear Dynamic Earthquake Responses——An Analysis of Stiffness of Bar Members in Consideration to the Nonlinearity and the Geornetrical Nonlinearity of Materials under Conditions of a Large Deflection
It introduces basic mode of cross section of inherent stress concrete member bar,discusses rigidity and strength of different inherent stress, and illustrates basic design principle of cross section of inherent stress concrete member bar,which to extend application of inherent stress concrete structure.
Finite-element method of large deflection springback for material is established on the potential energy theory and residual energy theory of large deflection springback for member bar and straight beam.
On the principle of energy variation, a stiffness matrix of bar members is here presented, including the influence of shear deformation of the member itself, and taking the nonlinearity and the geometrical nonlinearity of materials into conside- ration. Two kinds of implication of the 《P--Delta》 effect are analyzed. The working condition of the bar member at the elasto plastic stage has been rather comprehensively represented.
Compounds 5 and 8 with seven-member C ring were more active than etofylline and caused 100% relaxation of both the histamine and acetycholine pre-contracted guinea pig tracheal chain.
Ring signature allows specifying a set of possible signers without revealing which member actually produces the signature.
In this paper we report several 3D-preserved rare star-like fossils with finely preserved soft tissues which were recovered from the Kuanchuanpu Member of the Dengying Formation in South Shaanxi, China in 2003.
HNULP1, a new member of the basic helixloop-helix transcription factors, contains a DUF654 domain in its C-terminus and is highly conserved from Drosophilae, yeast, zebrafish to mouse.
Deniable ring authentication allows a member of an ad-hoc sunset of participants to authenticate a message without revealing which member has issued the signature, and the verifier cannot transfer the signature to any third party.
