为了计算瞬时溃坝最大流量,基于堰流与波流量相等原理,建立了瞬时溃坝最大流量与堰流关系,理论推导得到同一公式可以计算大坝全溃、横向局部溃坝、垂向局部溃坝及横垂向局部溃坝的瞬时最大流量的新通式,给出了该通式的基本和上限、下限及一般等通式。研究发现:瞬时溃坝流量与溃口堰坎类型有关,可以把瞬时溃坝最大流量、逐渐溃坝洪水或漫坝洪水的计算公式和相应系数统一到不同堰坎类型的堰流量计算中;而这些新通式相应系数的取值是被实验确认和经典著作肯定的,保证了系数取值的可靠和准确。这些新通式容易理解、形式简单、计算简便,参数取值可靠,把溃坝洪水计算的复杂问题转变为处理经典水力学的简单堰流计算。同时通过对比分析,充分论证了一般通式的合理性,并用国内外溃坝实例验证了计算方法和成果较科学、可靠、合理。

根据描述海面几何特性的Weierstrass分形函数模型,结合海水的介电特性,建立了复杂的二维海面电磁散射模型.该模型中,在传统的分形模型基础之上,将海水的介电常数看做海水盐度和温度的函数,推导出了海面的后向散射系数在入射波处于水平和垂直2种极化状态下的表达式.然后,在不同的频段下对海水的介电常数进行了分类讨论,得到了其在3个不同频段里的近似表达式,有助于实际电磁散射计算中的简化.最后,将模型的计算结果与传统的DV模型和测试的结果做了比较,发现该模型的结果比传统的DV模型的更接近于测试结果,误差仅约2 dB左右.因此,利用这一模型,可以得到较为全面而准确的海面散射系数.

2021年实施的《档案法》中存在一定数量的不确定法律概念,导致《档案法》语言模糊。这不仅减损了《档案法》应有的明确品性,也对档案开放和利用、相关档案主体合法权利保障及社会力量参与档案工作造成了一定的负面影响,亟须加以治理。但从另一个方面来说,不确定法律概念的存在也是弥补立法有限理性、增强档案主管部门行政能动性的必然结果。所以对它的治理不是要消除不确定法律概念,而是应当针对不确定法律概念背后的解释权、使用权进行规范,尽可能剔除其中的主观任性和恣意。有鉴于此,可以考虑建立一套包括行政合理性原则、裁量基准、事后救济机制等在内的综合体系,对《档案法》中不确定法律概念进行系统性规范。
