让我们回到上世纪60年代，理查德·奥巴瑞(RichardO'Barry)的名字就海豚的训练领域来说，算得上是全世界最有影响力的权威人士，他曾经以演员和训兽师的身份活跃在非常受欢迎的电视节目《海豚的故事》的拍摄现场……如今已经过去40多年的时间了，奥巴瑞却仍然保持着自己对海豚那异于常人的支配能力，通过驯兽师与海豚之间的合作表演，来赢得电视观众心满意足的笑声。

I think, via research, during the period of middle school, the application form of mathematical history in concept teaching should be "the form of being in harmony"; and we should choose the suitable mathematical history content according to the teaching content and the students' perceive; we should obtain concept through paying more attention to the latitudinous teaching and recreating principles; presenting the outcoming process of mathematical history through sight principles; improving the degree of the students' attaching themselves to the process .

中学阶段，数学史在概念教学中的应用遵循的原则主要有：应用形式为&融入式&为主；根据教学内容和学生的认知选择合适的数学史内容；在应用时应注重认知纬度的教学；遵循再创造的原则获得概念；遵循直观性原则呈现数学概念的演变过程；采用灵活多样的教学方式，提高学生的参与程度。

This paper studied the relationship between impulsive moment of radial tidal current and Alai phenomena, and concluded that: M acting on the earth's axis inspires Chandler wobble; the change of M depends on the interaction of the water, tidal force and the effects of the earth's rotation; under certain conditions, M changes dramatically during eclipse, which makes the amplitude of Chandler wobble change in the form of pulse.

本文研究了径向潮流冲量矩M与阿莱现象的关系，得出的结论是：M作用于地轴激发了Chandler摆动；M的变化取决于海水、引潮力和地球自转效应的相互作用；日食或月食期间，在一定的条件下，M变化的非常剧烈，引起Chandler摆动振幅脉冲式的变化，进而引起地球纬度的变化，最终导致地球表面重力加速度的变化；这种变化可以通过傅科摆摆动平面角速度的变化或重力计的示数变化反映出来。

Hunman's living system is complicated. There are immingled the circles of true and forth, of living and death, of ancient and contemporary, and of art and cross-subjects, but reflecting the history is the basis of all.

The southwest vortex restricted the development of the plateau vortex in some way at the early stage when it appeared in the lower atmosphere. When they were coupled longitudinally, the vertical difference caused by the different vorticity advections between the upper and lower levels excitated the updrafts under 500 hPa and strengthened cyclone vorticity, and then the positive vorticity at 500 hPa and 700 hPa increased by two times The change rate of positive vorticity facilitated the plateau vortex to move eastward.

分析表明：高原涡与西南涡涡心之间的纬向距离在5个纬度的时候，两者上升气流都在500 hPa以下，当两者继续东移，在经向上耦合的时候，二者同时得到发展，西南涡中心的上升气流达到300 hPa，而高原涡中心的上升气流突破200 hPa；西南涡在低层出现初期，在一定程度上制约了高原涡的发展，随着两者在经向方向发生耦合，上下涡度平流不同造成垂直差动，将激发500 hPa以下的上升运动与气旋性涡度加强，使得500 hPa与700 hPa涡心正涡度值的增大近 1倍。

The dominant and co-dominant species in shrub and herb layers were mostly helophytes and hygrophytes. With decreasing latitude, the helophytes and hygrophytes decreased or disappeared, while mesophytes increased.

研究区沟谷冻土湿地植物群落的灌木层和草本层的优势种和共优种多为适应湿地环境的沼生和湿生植物，随着纬度的减小，喜冷湿环境的沼生和湿生植物种类逐渐减少，甚至消失，而耐旱的中生植物的比重则逐渐加大。

Imamura (Ref. 1 , p. 346), a well-known seismologist, wrote as follows in 1937:" attacked with every resource at their command the various problems bearing on earthquake prediction, such as earth tiltings and earth pulsations, variation in the elements of terrestrial magnetism, variation in underground temperatures, variation in latitude, secular variation in topography, etc., but satisfactory results were not obtained".

Imamura〔参考文献26第346页〕，著名的地震学家，1937年写道∶'［委员会］利用他们能够调动的一切资源对地震预测有关的所有问题进行研究，包括地倾斜、地跳、地磁因素的变化、地下温度的变化、纬度的变化、地形学方面长期，等，但是未能获得令人满意的结果。

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。
