水准面

A simple algorithm is derived from linear Molodensky series solution for cm-order precision of quasi-geoid.

推导出了适合厘米级似大地水准面精化的线性Molodensky解实用简便的算法公式。

High resolution digital topographic data is very essential for the scientific engineering tasks, e.

高分辨率的地形数据在基础地理信息系统、地球重力场建模和大地水准面求定等工程中至关重要。

It may vary above and below the geometrical ellipsoid of revolution by as much as 100 meters due to the uneven distribution of mass within the Earth.

如果在海洋中没有潮汐，海流和涡旋等运动，在大气中没有气压的变化，那么，大地水准面应和平均海表面一致。

So if we know the earth internal structures and its geodynamic processes, we can determine a unique geoid.

因此，如果知道了地球内部结构和动力学过程，我们可以唯一准确地确定大地水准面。

Geoid height above sea level is assumed to be zero, which is

大地水准面海拔高度为假定为零，这是

Therefore geoid refining is one of important missions for the establishment of the height datum in a country or a region.

因此，精化大地水准面是一个国家或地区建立现代高程基准的主要任务之一。

The main purpose of physical geodesy is to ascertain the outer Earth gravity field and geoid.

物理大地测量的主要目标是确定地球外部重力场和大地水准面。

Both the direct and indirect terrain effects need to be taken in the precise geoid determination of the Western China area.

在确定中国西部精确的重力大地水准面时，直接和间接的地形影响都应该被顾及。

Recommendations were also given to extend the present study to further improve the geoid determination.

文中对如何扩展当前的研究，更有效地确定大地水准面也提供了建议。

The reference height we have chosen is the one closest to the average height of the worlds oceans. This is called the Geoid.

我们一般选择的参考高度是最接近全球平均海平面的那个层，也就是所谓的大地水准面。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
