As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.

Wheat physiological char acte rs show two stages by the dividing line of anthesis.In prophase,it mainly forms tillerings,differentiates the floscules and small heads,forms the base of heads number and grains number.In anaphase,it mainly accumulates effectively dry substance ,makes certain the grains number and grains weight ,so we can confirm the t hree yield factors,that is,heads number,grains number and grain weight.

在小麦生理性状的表现上以扬花期为分水岭分2个阶段，前期主要形成分蘖，分化小花、小穗，决定产量构成的亩穗数和穗粒数；后期表现干物质的有效积累，确定粒数、粒重，从而构成产量的三大因素：亩穗数、穗粒数和粒重。

Cao Weideng that the number of parity between the number of hexagrams, if a and five, seven, nine and six and eight, between not simply be grouped into Yin and Yang Yao Yao, or even between the different between the odd there should be some distinction, it is recommended Shì number is a number between 1-10 hexagram known as the "10 digital hexagrams"(it could be called "easy" yet to be proved) will be used Han 6, 12, said the number of composition Yigua for "double-digit Gua"("three easy"), and also agreed that advocated by Mr.

其四，无论商周数字卦或战国时期天星观楚墓竹简数字卦，都将二、三、四甚至还有五、七等数字按奇偶、阴阳归并入一、六两个数字，证明&观象重视阴阳，那些具体数目并不重要&，数字卦只是对阴阳爻画卦的一种运用，因八卦六十四卦用于占筮而产生，而非徐先生所论那样存在着成千上万的含义不同的数字卦。

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。
