We established abstract functional spaces, proved that the plastic deformation power rate functional is strict convex and the friction power rate functional and the tensional stress power rate functional are convex. So, strict convexity of the total power rate functional 〓 can be obtained. Further, By nonlinear analysis theory, we proved the existence and uniqueness of minimal point of functional 〓.

本文首先建立了抽象的泛函空间,证明了塑性变形功率泛函是严格凸泛函,摩擦功率泛函和外力功率泛函是凸泛函,从而得到总能耗率泛函的严格凸性,进一步地,利用非线性分析的理论,得到总能耗率泛函有唯一的极小值点。

In the first part, we will first deal with the strong Bonnesen-style inequality (2.1.3) for closed convex curves in the plane (the numbers of formulae and references are those of them in the context below). Bonnesen had first proved the weaker inequality (2.1.2) in [12] and several years later, he outlined in his monograph [13] various Bonnesen-style inequalities including (2.1.3), he considered, however,(2.1.3) as a direct consequence of Kritikos theorem for convex bodies in higher dimensional Euclidean spaces,. Here, we will give an independent proof of the existence for inequality (2.1.3), and by the way, give an estimate on the width of the bi-enclosing annulus of closed convex curves in the plane.

具体地讲,在第一部分中,首先讨论平面上闭凸曲线的强Bonnesen型不等式(2.1.3)(公式的编号和参考文献的编号引自后面的正文),Bonnesen在文[12]中先证明了较弱的不等式(2.1.2),几年以后,在他的著作[13]中,讨论了多种Bonnesen型不等式,其中包括不等式(2.1.3),不过,他把(2.1.3)作为高维欧氏空间中凸体的Kritikos定理的直接推论,我们这里对不等式(2.1.3)给出独立的存在性证明,并且还对平面闭凸曲线的bi-enclosing环的宽度给出了一个估计。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.
