随着时代的发展、经济的繁荣、物质生活极大地丰富,运输行业迅速崛起,势必对公路有更高的要求,以满足社会的需要,使公路的寿命得以延长。路基的质量决定着公路的质量。文章主
分析了某教学楼的地基不均匀沉降的事故原因,采用柱墩架梁托底加固法,提高基础强度,减少差异沉降,达到了理想的加固效果.
In this paper, I have provided a brief introduction on M?bius transformation and explored some basic properties of this kind of transformation. For instance, M?
以磷灰石-硅灰石玻璃陶瓷(AW)粉和β-磷酸三钙(β-TCP)粉为原料.以硬脂酸为致孔剂.经模压成型、1170℃烧结制备磷灰石-硅灰石/β-磷酸三钙复合多孔支架材料(AW/β-TCP).采用X射线衍射(XRD
We consider two problems from stability theory of matrix polytopes: the existence of common quadratic Lyapunov functions and the existence of a stable member. W
用电池内外隔膜最大孔径等物性测试,发现隔膜粉粒在烧结时发生重排和滑移.由此隔膜最大孔径逐步变小.组装压力促使隔膜粉粒重排和滑移,但又有效地抑制和减小隔膜内缺陷的发展.由于
氧化反应引起裂纹愈合是结构陶瓷提高强度的一个重要途径.针对目前研究中缺乏定量性这一不足之处,本文从热力学和动力学角度研究了氧化反应与裂纹愈合、强度提高之间的定量关系
A real-time pricing system of electricity is a system that charges different electricity prices for different hours of the day and for different days, and is ef
In this work we introduce a modified version of the simple genetic algorithm (MGA) and will show the results of its application to two GMA power law models (a g
In this paper, we deal with the uniqueness problems on entire and meromorphic functions con- cerning differential polynomials that share fixed-points. Moreover,
