sea level elevation

Impact of land nature slope and sea level elevation on the economic development in the three gorges' area

三峡库区土地自然坡度和高程对经济发展的影响

Tidal waves after mean-sea-level rise were modeled by using spherical tidal wave equations with the tide-generating force being taken into account, and with open boundary condition being taken as forced tidal elevation.

采用球面潮波运动基本方程，利用开边界强迫水位条件和考虑天体引潮力，对海平面上升后渤、黄、东海的潮波运动进行了数值模拟。

The level of the ocean's surface, especially the level halfway between mean high and low tide, used as a standard in reckoning land elevation or sea depths.

海洋表面的水位，尤其是在平均高水位和低水位之间的平均位置的水位，用作计算陆地海拔和海水深度的标准。

The equation of continuity is then used to further get a 2-order elliptical equation satisfied by sea surface elevation, and the unpenetrable condition at the shore wall of semi-closed sea area is also derived by means of tidal level.

然后利用连续性方程进一步得到了海面升高即潮位所满足的二阶椭圆型方程，进而导出了以潮位形式给出的半封闭海区岸壁不可穿透条件。

Geographical situation and sea level elevation are the main influencing factors to the spatial distribution of water vapor press.

地理位置和海拔高度是水汽压空间分布的主要影响因子。

Elevation differences is small compared with the earth's radius, this is proportional to the height above sea level.

高程差与地球半径相比显得很小，它与海洋面以上的高度成正比。

Obtained in the study area above sea level elevation, topography amplitude map, three-dimensional map, contour, gradient and thematic maps, thematic maps of slope, mountain shadows, surface cutting degree plan. 2.

得出研究区的海拔高程图、地势起伏度图、三维立体图、等值线、坡度专题图、坡向专题图、山体阴影图、地表切割度图。

The density varies with the temperature, and g with the latitude and elevation above sea level.

但密度是随温度变化的, 而g则随海拔高度和地理纬度变化.

A barometric altimeter indicates height above sea level or some other selected elevation.

气压高度表用以指示海平面或另外某个被选定高度以上的高度.

We're probably at an elevation of about 13,000 feet above sea level.

我们可能在大约海拔13,000英尺的高度。
