And this paper researches projection ways of coordinate such as the Mercator projection, Lambert projection and linear projection to achieve the conversion of level rectangular coordinate by latitude coordinate and geography.

研究横轴墨卡托投影、兰勃特投影以及线性投影等其它坐标投影方式，实现地理经纬度坐标到平面直角坐标的转换，支持多比例尺地图。

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.

Live Map和Google Map都使用墨卡托投影，但并不像人们认为的那样他们使用WGS84基准面，虽然你在他们的API中输入的值是WGS84下的值。【译注：原因是WGS84基准面是基于椭球面的，而LiveMap和GoogleMap使用的是球面。另外，YahooMap使用的是等距圆柱投影。

Minus sign indicates west of prime meridian in longitude and south of equator in latitude.

We also used the latent heat daily data、sensible heat daily data、relative humidity data and OLR daily data from NCEP-DOE Reanalysis2 which formed as 2.5-degree latitude x 2.5-degree longitude global grid with 144x73 points(1982～2005). The data of subtropic high ridge offered by Bational Climate Center . With singular value decomposition analysis, we studied key region of ocean-atmosphere interaction in the mid-latitudes in the Pacific. Second, by using wavelet analysis to study the character of the key regions of SST.Moreover the correlation analysis can help us to understand the reason of the cold water formed and the physical process of ocean-atmosphere interaction in the mid-latitudes in the Pacific. There are three mostly SVD modes which contribution reach to 70%,So the three mostly modes can reflect the mostly structure in the key region.

The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO－LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO－LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km . 4 The RAAN of TS and RS has a great influence on the LEO－LEO occultation number, but has little influence on occultation distribution.

结果指出：1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距；而这些参数对一年掩星事件的经度分布影响都不大；2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大，两卫星倾角接近互补时掩星事件最多，两颗LEO卫星中与90°相差较大的倾角决定了LEO－LEO掩星事件的纬度分布范围；3发射卫星和接收卫星处于同一轨道高度时，LEO－LEO掩星事件数取得极大值，发射卫星和接收卫星都采用600 km的轨道高度，一年LEO－LEO掩星事件数最多；4 发射卫星和接收卫星升交点赤经的相互关系对LEO－LEO掩星事件数量影响很大，发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多，RAAN对掩星事件纬度和经度分布影响不大；5近地点角距对掩星事件数量和分布影响都不大。

In the region, the winter mesospheric westerly jet lies at 75km altitude and in between 25°-35°N, which is 10km higher and 5°farther south in latitude that of the CIRA-86. While not shown in CTRA-86, there is a clear easterly band extending from the equator to high latitudes at the altitude of lower thermosphere in autumn.

在冬季，东亚区域中间层西风急流中心位于25°-35°N之间的75 km高度，与CIRA-86相比，该中心纬度偏南5°，高度偏高10km；在秋季，东亚区域低热层高度存在一个显著的从赤道到高纬度的东风带，而CIRA-86不存在。

One of the determinations was a large scale latitude measurement carried out in 1279 A.

公元1279年的大规模的纬度测量就是其中的一项工作。

Moreover, daily analysis disclosed the extreme complexity in the appearance of the mid-latitude mesopause. It was observed that there are two kinds of mesopause, one locates at 83 km height with extremely low temperatures, the other locates at about 100 km.

逐日分析结果还揭示了中纬度地区夏季中间层顶异常复杂的表现，结果表明在这里可以看到两种位于不同高度的中间层顶，第一种位于83 km并且伴随异常低温，而另一种位于约100 km高度。

Making use of structural characteristics of the Lower Latitude Meridian Circle and the error theory of this instrument, we have developed a method used to measure directly instantaneous atmospheric refraction, and moreover built a local observational astronomical refraction model toward the east, south, west and north of Yunnan observatory that is classified according to the star's spectral type.
