查找岩溶区湖泊水库渗漏通道是岩溶区湖库建设和渗漏灾害治理的“卡脖子”问题。文章以碧云湖为例,分析湖区周边水文地质条件,结合示踪试验和地球物理探测方法,确定了碧云湖渗漏水文地质条件和渗漏主管道位置,并通过钻探验证。结果表明,碧云湖渗漏主要为岩溶管道型,渗漏点和地下河管道主要发育在靠近八步复式向斜轴的部位,位于物探测线测点540 m处,管道深约40 m,渗漏段相对较窄,灌浆堵漏可行。根据水文地质调查、地形地貌条件和地球物理探测结果,建议在水库下游方向的物探测线开展帷幕灌浆,以测点540 m为中心向两边灌浆。

In microfluidic technology, dielectrophoresis(dep) is commonly used to manipulate particles. In this work, the fluid–particle interactions in a microfluidic system are investigated numerically by a finite difference method(FDM) for electric field distribution and a lattice Boltzmann method(LBM) for the fluid flow. In this system, efficient particle manipulation may be realized by combining dep and field-modulating vortex. The influence of the density(ρ_(p)), radius(γ), and initial position of the particle in the y direction(y_(p0)), and the slip velocity(u_(0)) on the particle manipulation are studied systematically. It is found that compared with the particle without action of dep force, the particle subjected to a dep force may be captured by the vortex over a wider range of parameters. In the y direction, as ρ_(p) or γ increases, the particle can be captured more easily by the vortex since it is subjected to a stronger dep force. When u_(0) is low, particle is more likely to be captured due to the vortex–particle interaction. Furthermore, the flow field around the particle is analyzed to explore the underlying mechanism. The results obtained in the present study may provide theoretical support for engineering applications of field-controlled vortices to manipulate particles.

This paper presents a multi-interface embedded server architecture for remote real-time monitoring system and distributed monitoring applications. In the scheme,an embedded microprocessor( LPC3250 from NXP) is chosen as the CPU of the embedded server with a linux operation system( OS) environment. The embedded server provides multiple interfaces for supporting various application scenarios. The whole network is based on local area network and adopts the Browser / Server( B / S) model. The monitoring and control node is as a browser endpoint and the remote node with an embedded server is as a server endpoint. Users can easily acquire various sensors information through writing Internet protocol address of remote node on the computer browser. Compared with client / server( C / S) mode,B / S model needs less maintain and can be applicable to large user group. In addition,a simple network management protocol( SNMP) is used for management of devices in Internet protocol( IP) networks. The results of the demonstration experiment show that the proposed system gives good support to manage the network from different user terminals and allows the users to better interact with the ambient environment.
