82B线材脆性断裂原因分析

82B线材在终轧后冷速过快导致表层出现马氏体是引起脆性断裂的原因之一.心部成分偏析导致奥氏体过冷,从而使马氏体出现在轴心部位,在拉拔过程中轴心马氏体断成竹节状,变成脆性断裂的裂纹源.大型脆性的夹杂物也是引起线材脆性断裂的起源.     

Influence ofβ-cyclodextrin as an encapsule and as an inclusion complex dopant on conducting polyaniline

An investigation on the effect ofβ-cyclodextrin (CD) in both free and inclusion-complexed forms with a guest anionic metal complex, dioxalatodiaquochromate(III) (DDC), on the characteristics of conducting polyaniline (PANI) is carried out. Four materials, PANI (i.e. PANI-SO ₄ ²⁻ ), PANI-DDC, PANI-CD and PANI-CD + DDC were prepared byin situ chemical oxidative polymerization in aqueous H ₂SO₄ at pH 1 and subjected to electrical conductivity and spectral (IR and UV-vis bd measurements. DDC and CD when separately incorporated, reduce the conductivity of PANI by about half whilst their inclusion complex CD + DDC enhances it. Spectral characterization reveals that DDC as a dopant and CD as an encapsule exhibit their effects through adverse interaction with imine-amine N centres and benzenoid moiety of PANI. The inclusion complex CD + DDC, on the contrary, functions as a dopant by lying in between the chains and seems to promote the extended conformation of PANI chain and hence theπ -electron delocalization. Exposure of the material to methanol vapour causes a decrease in conductivity in PANI and PANI-CD while an increase in PANI-CD + DDC. This study makes explicit the distinct role of CD as an encapsule and CD + DDC inclusion complex as a dopant in altering the electrical property of PANI.     

An elliptical disc anchor in a damage‐susceptible poroelastic medium

A flat rigid elliptical anchorage located in a damage‐susceptible fluid‐saturated poroelastic medium is subjected to an in‐plane load, which induces a pure translation in the plane of the anchor. This paper develops computational estimates for the time‐dependent displacement of the disc anchor for the classical problem that involves Biot consolidation and compares the results with situations where the porous skeleton can experience micro‐mechanical damage that leads to an alteration in both its elasticity and fluid transport characteristics.

A Boy and Two Mothers: New Variations on an Old Theme or a New Story of Triangulation? Beginning Thoughts on the Psychosexual Development of Children in Nontraditional Families.

The author examines the ways in which a psychoanalytic perspective may illuminate the underlying developmental dynamics of children of lesbian parents. Families headed by gay and lesbian parents demand reconsideration of a theory of oedipal development based on heterosexual parents. If triangulation, the move from dyadic to triadic object relationships, depends on 2 primary processes--the child's acceptance of the immutability of generations and the child's recognition that children are excluded from the world of adult sexuality--parental gender or sexual orientation assumes less importance. The emergence of conscience from multifaceted processes of identification is consistent with this view of triangulation as a developmental phase. Children of gay and lesbian parents must be offered theories of healthy development that include them. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
