全面从严治党和党的自我革命是新时代党建话语体系的重要概念。党中央的决策部署和现行党章党规赋予了两者各自的时代意涵和战略属性,两者所承载和发挥的功能也有分殊,但又在话语阐释上表现出高度关联性。通过梳理相关政策内容和党章党规,可从宏观上将两者关系界定为相互区别、有机统一、互为因果的三种样态。同时,从两者有关话语生成的时间条件、价值追求的同向驱动、党的建设的双重保障、管党治党的战略选择来看,新时代党的建设新的伟大工程成为全面从严治党和党的自我革命的结合场域,且三者之间紧密交织。

在改革开放和社会主义现代化建设新时期,邓小平从依靠制度管党治党的高度,围绕党规党纪建设进行了深入思考和积极探索。一是要通过党规党纪建设,强化党的领导和提升组织优势。二是要处理好党规党纪同理想、民主、权利的关系,确保党规党纪建设的科学完善。三是要正确认识党规党纪与国家法律的关联,“国要有国法,党要有党规党法”,两套制度规范体系都必不可少,同时又要保持彼此的必要分工和边界。四是要确保党员自觉遵规守纪,党组织严格执规执纪,全体党员在党规党纪面前一律平等,严格遵守政治纪律,领导干部要率先垂范,同时还要发挥监督机构的保障作用。重温这一时期邓小平对党规党纪建设的认识和思考,对于我们进一步理解党规党纪的理论问题、推动党规党纪的实践发展具有重要启示意义。

火星超低雷诺数环境导致螺旋桨系统气动特性相比于地球环境显著恶化,翼型表面层流分离现象影响了火星螺旋桨的气动特性.为设计出适应火星低雷诺数环境的螺旋桨,深入了解超低雷诺数对翼型气动特性的作用机理,采用Transition SST转捩模型求解非定常可压缩N-S方程的数值模拟技术,对几种适用于低雷诺数环境的翼型进行火星超低雷诺数环境下气动特性模拟计算,从而选取最适应火星大气环境的翼型.结果表明CLF5605翼型具有更好的气动性能.对选定的翼型进行不同超低雷诺数下气动特性模拟计算,揭示了超低雷诺数对翼型气动特性的影响,即在火星大气雷诺数范围内,更高的雷诺数对应更好的气动性能;对雷诺数从100~20000翼型表面边界层状态进行数值模拟,发现翼型层流分离结构发生显著变化,从低雷诺数下的层流边界层状态,随着雷诺数的增加开始发生层流分离,在翼型尾缘产生层流分离泡,并最终变成湍流边界层.采用最小能量损失的方法设计火星螺旋桨,对其气动性能进行了数值模拟仿真,并对轻量化制造的螺旋桨进行了地面台架实验验证,通过将地面实验结果与CFD数值模拟仿真结果对比,验证了螺旋桨轻量化设计合理性以及数值计算的准确性.
