A novel multi-probe micro-fabrication apparatus was developed based on the friction-induced fabrication method. The main parts of the apparatus include actuating device, loading system, and control system. With a motorized linear stage, the maximum fabrication area of 50 mm × 50 mm can be achieved, and the maximum sliding speed of probes can be as high as 10 mm/s. Through locating steel micro balls into indents array, the preparation of multi-probe array can be realized by a simple and low-cost way. The cantilever was designed as a structure of deformable parallelogram with two beams, by which the fabrication force can be precisely controlled. Combining the friction-induced scanning with selective etching in KOH solution, various micro-patterns were fabricated on Si(100) surface without any masks or exposure. As a low-cost and high efficiency fabrication device, the multi-probe micro-fabrication apparatus may encourage the development of friction-induced fabrication method and shed new light on the texture engineering.

对设计强度为10MPa的混凝土立方体试件进行三轴压缩试验,系统研究了等围压条件下混凝土的强 度和变形特性,围压分别为0,4,8,12,16MPa5个量级;同时研究了不等围压条件下混凝土强度变化特性, 试验表明,随着围压增加,混凝土的极限抗压强度有明显增强的趋势;随着小主应力的增加,中主应力的影响 有减弱的趋势;峰值应力处应变随围压增加幅度显著。得出了在不同恒定围压下混凝土的应力应变全过程曲线; 通过与当前文献资料的对比分析,指出了在混凝土结构计算中适用的强度及变形表达式,为工程实践提供了 依据。

Kawai型碳化钨多面砧压机的压力突破 Review

在众多领域中都需要扩大Kawai型碳化钨(tungsten carbide, WC)多面砧压机的压力范围,尤其是在地球科学领域。然而,40年来,在压力产生方面没有取得重大进展。我们最近的研究已经将采用碳化钨压砧的Kawai型多面砧压机的压力产生范围扩大到65 GPa,这是该装置高压产生范围的世界纪录,比传统压力产生范围增大了2.5倍以上。我们还成功地在高温下产生了约50 GPa的压力。本文回顾了我们最近发展的高压技术。室温和高温下高压的产生是通过以下技术的结合来实现的:①精确对准的滑块系统;②高硬度的二级压砧;③二级砧面锥形化;④由高体积模量材料组成的高压腔体;⑤炉体隔热性高。我们的高压技术将有助于研究在下地幔上部条件下材料的相稳定性和物理性质,并且能够合成和表征新材料。
