截渗墙(防渗墙)质量检测技术研究进展

截渗墙是堤坝整治的重要手段，但由于截渗墙施工质量不易控制，并且具有隐蔽性等特点，截渗墙的质量检测非常重要且存在不小的难度。本文首先简要介绍了近年来得到研究与实践的一些截渗墙质量检测技术，并对各种检测技术的特点进行了分析，最后推荐了截渗墙(防渗墙)质量检测的技术方案。

The first ISPRS software contest for computer-assisted teaching (CATCON)

The first ISPRS software contest for computer-assisted teaching, CATCON, took place on July 12, 1996 at the ISPRS Congress in Vienna. The main objective of the contest was to promote the development and dissemination of good/user-friendly software packages for computer-assisted teaching. Ten software packages and one data set from six countries were nominated. All the software and the data set were demonstrated at the contest, and prizes were given to three software packages and to one data set.

Roll Vortices and Boundary-Layer Development during a Cold Air Outbreak

The development of the boundary layer during a cold air outbreak in the FramStrait is documented by aircraft measurements. The convection was organisedinto roll vortices with aspect ratios increasing from 2.9 near the ice edgeto more than 6 at 100 km further downstream. This increase coincides with anincrease of the latent heat release in the cloud layer. The stability parameter-zi/L varies from about zero at the ice edge to 30 at a distance of 200 kmdownstream over open water where the satellite picture still shows cloudstreets. The increase is mainly due to the deepening of the boundary layer.The turbulent vertical sensible and latent heat fluxes near the surface amountto 400 W m^-2 within a 300 km off-ice zone. 25% of the upward heat fluxin the subcloud layer is carried out by organised roll motions. Experimentswith a 2-dimensional non-hydrostatic model show a similar roll aspect ratio inthe first 50 km, but further downstream where condensational heating is moreimportant the modelled roll wavelengths are distinctly smaller than the observedones.     

区域持续发展的基本理论及其实践意义

区域持续发展是从实践中提出的重大课题，理论滞后于应用为其基本现实。没有理论的行动是盲目的。区域持续发展理论建设已迫在眉睫。理论建设包括科学体系、理论基础、基本理论和核心理论层次，本文主要对其基本理论层进行论述，认为现代人地关系协调论、区域PRED系统论、区域发展控制论和人地相互作用潜力论构成了区域持续发展的基本理论，这些理论对于构建区域持续发展核心理论以及指导当前的区域持续发展实践有着极为重要的现实意义。
