摘要：This paper analyses the geometrical analogue rules of explosively formed projectile (EFP) penetrating armours with the help of similarity theory, and establishes EFP penetrating armour simulation law. Based on the simulation law established here, prototype experiments and model experiments with the simulation ratio of 1.33 are designed, and the penetrating armour experiments with 45 # carbon steel plates are separately conducted. By means of data processing of experimental results, it is concluded that EFP penetrating armour simulation law established is tenable.

摘要：Biocompatible designed micromotor has attracted more and more concerns in the field of biomedicine due to their self-propulsion and delivery *** micromotors,mostly consisting of alkali earth metals,hydrogels,or other motile biomaterials,can effectively transform chemical energy into mechanical or kinetic energy to achieve the expected delivery of cargos to the sites of *** for conveying power,the modifiable surface and inner cavity of micromotors guarantee that their potential as versatile delivery systems for therapeutic ***,this review generalizes the propelling mechanisms,composites,and shapes of ***,the application of micromotor-derived composites for biomedicine delivery and other versatile purposes are also discussed.

摘要：地基土承载力的确定方法很多,但各种方法得出的结论差异性较大。以南京江北某雨污分流管线勘察工程为实例,通过大量的原位和室内试验,运用多种方法提出了地基承载力,并进行成果对比,依据地区规范提出了典型地层承载力的建议值。研究结果可对南京江北长江阶地区的岩土工程勘察设计提供参考依据。
