界面

Its territory resources are important conditions and physical foundations for economic development of the coastland.

海岸带作为海陆地理过程界面和国内与国外经济势能锋压，具有独特的区位条件和丰富的自然资源。

First,the design method of human-center in CoEditor is expounded.

该文首先阐述了CoEditor的以人为中心的设计思想，然后就该编辑器实施中的4层文档库设计、人－人交互界面构造、对用户透明且加锁粒度可变的并发控制机制、跟踪闭环链的检测和解除以及以人为中心的检索等问题的实现方法进行了论述。

AVO analysis is suggested for solving to solve the difficulty in identification of thin alternating layers in exploration of oilfields. It can improve the current method that has no thickness variable in the formula of reflective and is limited by sampling rates in calculation of the coefficient in the time of domain. Using the relationship of stress and displacement on two interfaces, this paper derives the spectrum of reflective coefficient for any incidence angle and thiekness of thim layer based on the equation of seismic wave propagation in the frequency domain.

针对油气田开发中薄互层认识难的问题，提出从AVO分析解决困难，克服现有方法在反射系数公式中无厚度变量、时间域计算反射系数谱受采样率限制的不足，运用两个界面间位移与应力关系，从频率域地震波传播方程推导了任意入射角和薄层厚度下的反射系数谱。

Though they work together to form a cohesive user interface, each activity is independent of the others.

虽然它们作为一个整体的用户界面进行协同工作，但是每一个活动却是独立于其它的活动。

Thus it is essential to apply the theories of colloid and interface chemistry to the studies on the properties of the particles in the reach.

用胶体界面化学理论特别是胶体稳定性理论探讨长江口泥沙的特性十分必要的。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
