查询词典 asymptotic curve

To establish GPS buoy above the surface near Tide Gauge for continuously monitoring sea level change and dealing with the dynamic relative positioning of the GPS tracking station integrated with the Tide Gauge, the instantaneous position of GPS buoy can be solved. Then based on ellipsoid height of each point and time series, the curve of height distribution is drawn. The curve can represent the instantaneous position of the sea surface.

在潮位站附近海水面上设置GPS浮标，持续量测海水面之变化，并与潮位站共构之GPS连续追踪站，进行动态相对定位，可解算出GPS浮标瞬间位置，再撷取其椭球高，以时间序列绘制此高程分布图，此曲线就代表海水面随时间变化之瞬间位置。

The priorities are the diversification characteristics of each targetin the subsequent water flooding. According to diversification characteristics of these targets,the paper studies how the heterogeneousness, water flooded condition, interconnectingcondition of zone;key measures injector parameters affect these targets from polymer floodingmechanism. Based on influence equations, production target prediction models are built usingHall curve theory, relative permeability curve, relations of water saturation and relativepermeability and material balance equation. Parameters of models are calculated by the way ofcomputer program and so that a simple, fast way have been gained to predict production targetof polymer subsequent flooding.
