运用测量剩余电阻的方法,研究了4.2K温度时不同纯度的铍中剩余相的分解与其溶解动力学。结果表明:时效有效温度取决于金属中含有杂质的数量,随杂质数量的增加而提高;高纯度铍(～99.94%)如微合金一样也具有时效倾向;应用剩余电阻概念研究纯铍内部结构转变是非常有效的方法,它可记录时效过程初始阶段的变化(如400℃铍中扩散分解),这些变化用微观观察或X射线衍射分析很难得到。

研究NiTi形状记忆合金在应力下等温保温过程中的应变变化。为了研究可恢复应变,对Ni_(51)Ti_(49)和Ti_(40.7)Hf_(9.5)Ni_(44.8)Cu_(5)合金进行3种制度的保温处理,分别是:应力下冷却后在应力下保温(制度1);无应力和载荷下冷却后在应力下保温(制度2);具有双向形状记忆效应的样品在应力下保温(制度3)。结果表明,所有制度中,在应力下保温后样品均会发生应变变化。该应变在后续热处理或卸载后能恢复,因此表明应变变化是由等温马氏体相变引起的。这种等温应变取决于合金的化学成分、等温保温制度、应力和保温温度。Ti_(40.7)Hf_(9.5)Ni_(44.8)Cu_(5)合金(制度1)和Ni_(51)Ti_(49)合金(制度2)的最大等温应变分别为3.4%和6.1%。制度3中的保温伴随着较小的应变(小于0.3%)。讨论储存弹性能对等温马氏体相变的影响,结果表明,当相变伴随着较小的储存弹性能时,等温应变较大。

We propose the generalization of Einstein’s special theory of relativity (STR). In our model, we use the (1 + 4)-dimensional space G, which is the extension of the (1 + 3)-dimensional Minkowski space M. As a fifth additional coordinate, the interval S is used. This value is constant under the usual Lorentz transformations in M, but it changes when the transformations in the extended space G are used. We call this model the Extended space model (ESM). From a physical point of view, our expansion means that processes in which the rest mass of the particles changes are acceptable now. In the ESM, gravity and electromagnetism are combined in one field. In the ESM, a photon can have a nonzero mass and this mass can be either positive or negative. It is also possible to establish in the frame of ESM connection between mass of a particle and its size.

This work aims to establish a scientific and engineering background in the production of cast multicomponent alloys and metalmartix composite (MMCs) via Self-Propagating High Temperature Synthesis (SHS, combustion synthesis) which is a novel process technique regarding fast and low-cost production ability. We carried out the search for reactive systems and process parameters that would ensure preparation of cast multicomponent materials in a single process. The principles and methods of the SHS thermite-type reaction processes have been investigated under high-gravity values applying loads up to 1000 g with special centrifuge set-up. In this way we expected to improve the yield of target product, remove gaseous byproducts, diminish the grain size in the product, and make product composition more uniform. The obtained results can be expected to make a theoretical background for industrial-scale manufacturing of heat-resistant intermetallic alloys, master alloys, catalysts, MMCs etc.

In the bone marrow, B cells and bone-resorbing osteoclasts colocalize and form a specific microenvironment. How B cells functionally influence osteoclasts and bone architecture is poorly understood. Using genetically modified mice and highthroughput analyses, we demonstrate that prolonged HIF-1α signaling in B cells leads to enhanced RANKL production and osteoclast formation. In addition, deletion of HIF-1α in B cells prevents estrogen deficiency-induced bone loss in ***, estrogen controls HIF-1α protein stabilization through HSP70-mediated degradation in bone marrow B *** stabilization of HIF-1α protein in HSP70-deficient bone marrow B cells promotes RANKL production and *** of HSP70 expression by geranylgeranylacetone(GGA) administration alleviates ovariectomy-induced ***, RANKL gene expression has a positive correlation with HIF1 A expression in human B cells. In conclusion, HIF-1αsignaling in B cells is crucial for the control of osteoclastogenesis, and the HSP70/HIF-1α axis may serve as a new therapeutic target for osteoporosis.
