The interface wave traveling along the boundary of two materials has been studied for nearly a century. However, experiments, engineering applications, and interface wave applications to the non-destructive inspection of interlaminar composite have developed slowly. In this research, an experiment that applies Stoneley waves (a type of interfacial wave between two solid half-spaces) is implemented to detect the damage in a multilayer structure. The feasibility of this method is also verified. First, the wave velocity and wave structure of Stoneley waves at a perfectly bonded aluminum-steel interface are obtained by solving the Stoneley wave dispersion equation of two elastic half-spaces. Thereafter, an experiment is conducted to measure the Stoneley wave velocity of an aluminum-steel laminated beam and to locate interlaminar cracks by referring to the Stoneley wave velocity and echo wave time. Results indicate that the location error is less than 2%. Therefore, Stoneley waves show great potential as a non-destructive inspection method of a multilayer structure.

The Loess Plateau is the core area in the Yellow River basin for implementing environmental protection and high-quality development strategies. A series of ecological projects has implemented aimed at soil and water conservation and ecological management on the Loess Plateau over the past 70 years. The effects of the ecological projects are apparent mainly through a marked increase in vegetation cover, controlled soil erosion and reduced flow of sediment into the Yellow River, continual optimization of the industrial structure and increased production from arable land, poverty alleviation and greater prosperity, and optimal allocation of space for biological organisms. Major problems have also been analyzed in ecological management including the fragile ecosystem of the region, maintaining the stability of vegetation, lower agricultural productivity and continued risk from natural disasters. Some suitable schemes and models have been developed for the coordinated development of the region through research and demonstration, striking the optimum balance between rural industry and ecology, and increased regional capacity to supply high-quality ecological products. Countermeasures to address the problems are suggested to guide ecological management and high-quality development in the future.

污染物在流域水土环境中存在复杂的源汇关系,在水土环境中的转化作用主要受控于各种水‒ 土界面过程,为此,水土环境污染治理需将水土环境作为一个整体,通过跨介质归因识别找到真正的污染源,然后进行跨介质治理。本文首先分析了污染物在流域水土环境中的跨水‒ 土介质迁移过程以及主要影响因素,在此基础上提出了流域水土环境跨介质调控原理及关键过程,主要包括流域水土环境污染跨介质归因识别和流域水土环境污染跨介质治理。同时,重点阐述了污染物在河道外的土壤‒ 水界面、坡面‒ 河道界面,河道内的水‒ 沉积物界面(包括河床潜流带和侧向岸边潜流带的水‒固界面)和水‒ 悬浮颗粒物界面过程在跨介质去除中的重要作用,并采用实际案例阐述了流域非点源污染物的跨介质控制、河流含氮化合物的跨介质去除以及湖泊氮磷的跨介质去除方法等。研究结果可为流域水土环境污染防治提供科学依据。
