In light of different sources of data, three groups of affecting factors, that is, 1 mean annual air temperature; 2 longitude, latitude and elevation; and 3 mean annual air temperature, longitude, latitude and elevation; were designed as auxiliary variable, and the regression kriging method was adopted to predict the spatial patterns of mean annual soil temperatures across the country.

本文用我国698个气象站点的年均土壤温度和年均气温数据以及数字高程模型数据，分析不同气象和地形因素对年均土壤温度的影响；根据全国各地可获取数据源的不同，分别用3组不同的影响因素为辅助变量：(1)年均气温；(2)经度、纬度和海拔；(3)年均气温、经度、纬度和海拔，采用回归克里格法预测我国年均土壤温度空间分布。

Additionally, the hinge will point north, and the diptych will be angled so the gnomon is parallel to the Earth's axis of rotation. At solar noon, sunrise and sunset, the latitude adjustment of the diptych can't affect the time of either sundial, but at 9am and 3pm, each degree of latitude error (from holding the sundial at the wrong angle) creates four minutes of difference between the two faces.

另外，当绞链朝向北方，摺叠式日晷被旋转了一个角度，晷针才能与地球的自转轴平行，则当正午、日出与日落时，摺叠式日晷的时间不会受到纬度改变的影响，但是在早上9点和下午3点，纬度每偏差1度，在两个晷面上的时间便会相差4分钟(肇因於日晷在错误的纬度上)。

Podocarpus nagi are the least.(5) Comparing the plant communities from different latitudes, it shows that the rule of community species diversity and community tree layer diversity index change as the latitude changes according with Wlater and Whittakers conclusion about Shannon-Wiener index decrease as latitude increase.

5与不同纬度的植物群落的比较结果表明：群落物种多样性和群落乔木层多样性指数随纬度的变化规律符合Wlater和Whittaker关于Shannon－Wiener指数随着纬度的升高而降低的结论，即与群落物种多样性的纬度趋势一致。

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。

Large supply of non-hybrid seeds for vegetables, grains and herbs; make sure they are of the non-GMO, non-hybrid, propagating variety; also be sure to have instructions on how to harvest seeds including information on "moldering" techniques to properly collect seeds from certain plants such as tomatoes; note lastly that due to damp low-sunlight conditions many crops will not grow without growing lights and protection from rain; special research is therefore required on which crops will grow best (for instance, patty rice should grow better than wheat under damp conditions); also be sure to take into account the climactic change which results from the change in latitude due to the pole shift as a location which does not change greatly in latitude will fare better than one which falls in the vicinity of the new poles for instance; the pole shift theory presented on Zeta Talk states that the terrestrial North Pole will move to the middle of the Atlantic off the bulge of Brazil and ultimately one will need to observe the climate and the position of the sun to figure out the new latitude, and either adapt or re-locate as needed

要有许多蔬菜，谷物和草药的的非杂交种子；确信它们是非转基因，非杂交的，是用于繁殖的品种。也得确信具有怎样收获种子的指导书说明，包括&制造&技术方面的信息，以便恰当地收集某些植物的种子，例如西红柿。最后得注意，由于幽暗的低阳光环境，在没有阳光，以及没有其进行雨水防护的情况下庄稼将不会下生长。因而需要进行特别的研究，看看哪种庄稼在这种条件下生长得最好（例如，在昏暗的状况下，水稻应该比小麦生长的更好）。也要确信考虑了极移造成纬度改变，因而导致气候变化。例如，与那些位于新极点附近的地方相比，纬度变化不特别大的地方情况要好得多。齐塔人之声讲述的极移理论表明了地球北极会移动到大西洋中部的巴西隆起处。最后需要观察气候状况以及太阳的位置，以弄清楚新的纬度，根据需要，即可适应当地的条件，又可再次搬迁。

The Tibetan tropopause is obviously different from the other regions at the same latitudes, c.a. 0.7 km higher in average, and the seasonal height variation of tropopause over Tibet is distinguished, in amplitude and phase, over the corresponding latitudes.

The temperature trend rate at Kushka station, which has the lowest latitude, is 0.018℃/a, and that at the other four stations is less than 0.01℃/a. The warming trend at Kushka, Almaty, and Tomsk stations, which are at relatively low latitudes, is significant, and it changed abruptly during the period from the l970s to the l980s. The rise of the minimum temperature is more obvious than that of the maximum temperature, and the warming phenomenon at Kushka station is the most significant. The precipitation trend rate at the five stations is about 0.09% per year, and the trend is not significant.
