The progress levels of symptoms after pathogen infection showed that interaction of gray leaf spot pathogen and host has differentiation or polymorphism. The progress levels of symptoms is different.The aggressively has polymorphism. The pathogenicity of different isolates in same cultivar has polymorphism, or the host reaction type of same isolate in different cultivars has polymorphism.The host reaction type has differentiation. There are seven types of host reaction in cultivar and inbred after infected by GLS pathogen:Rectangular lesion without chlorotic halo, Rectangular lesion with chlorotic halo,Irregular lesion without chlorotic halo,Irregular lesion with chlorotic halo, Spot lesion with chlorotic halo,Rectangular and irregular lesionand Rectangular and spot lesion. The host reaction type is coalesced lesion when disease severely. Frequency of each reaction types is different.

通过对玉米灰斑病菌侵染后的显症过程的系统观察，可在组织水平上说明该病菌与寄主互作反应存在分化或多样性：玉米灰斑病菌不同菌株侵染后显症过程表现出明显的差异；玉米灰斑病菌在侵袭力上存在多样性，菌株间对同一种品种的致病性表现多样化，或者同一菌株对不同品种侵染引起的寄主反应表现为多样性；病斑反应型的分化，玉米灰斑病菌侵染玉米品种或自交系后，主要有7种病斑反应类型，即RH型、RN型、IRH型(不规则形具褪绿晕圈病斑)、IRN型(不规则形无褪绿晕圈病斑)、SH型、RI型(长矩形与不规则形混合病斑)和RS型(长矩形与斑点形混合病斑)，若发病严重，病斑连成片，而且这些反应类型出现的频率也不同。

During the New Moon (the 1st of a lunar month) and the Full Moon (the 15th of a lunar month) when the Earth, Moon, and Sun lie in a straight line, the solar and the lunar tides overlap and the sea-level pressure is lower than the mean at the Airport, because the tide-producing force induced by the Sun and Moon reaches maximum. On the other hand, during the First Quarter (the 7th day of a lunar month) and the Last Quarter (the 21st of a lunar month) the Sun-Earth's and the Moon-Earth's relative positions are perpendicular to each other with respect to Earth, the solar and the lunar tides interfere mutually, the Airport sea-level pressure is greater than the annual mean due to the tide-producing force reaching minimum.

松山机场在朔望月里，每逢阴历朔日或望日，受太阳与月球之引潮力(Tide-producing force)方向一致，太阳潮和太阴潮重叠影响，其全日和逐时平均海平面气压比年平均为低；而每逢上弦和下弦时，日地与月地的相对位置成直角，太阴潮和太阳潮相干扰，其全日和逐时平均海平面气压则比全年平均为高。

In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

本文推导了基于月球参考球的各种投影公式，主要包括方位投影、圆柱投影和圆锥投影；编制了月球地图投影计算软件；对多种月球的投影变形进行了详细的计算，总结分析了各种月球投影的变形规律；结合月球探测的需要，给出了月球投影方案的建议：对于局部的面积较小的投影区域，建议使用等角方位投影或外心透视方位投影；如果绘制月面全图，在两极10°范围内采用等角方位投影或外心透视方位投影，其余区域可以采用等角横切圆柱投影和等角正割圆锥投影，并且要进行分带处理。
