Conclusions: The pathological changes of the parotid duct in SS could be divided into 6 stages, ie, normal appearance of parotid duct, early stage of pathological changes of terminal ductules, late stage of pathological changes of terminal ductules, pathological changes of parotid trunk and branches of parotid duct, early-stage of gland atrophy, late-stage of gland atrophy.

Field obserbation and laboratory study indicate the main type of rock alterationwere K-feldsparization, biotitization, sericitization, silication, epidotization,chloritization and carbonatization. From early to late, these alteration could dividedinto three epochs: early-stage was K-feldsparization-biotitization, middle-stage wasquartzification -sericitization, late-stage was silication, carbonatization, epidotizationand chloritization.

通过野外观察及室内研究表明，围岩蚀变类型主要有钾长石化、黑云母化、绢云母化、硅化、绿帘石化、绿泥石化和碳酸盐化，从早至晚可分为三期：早期为钾长石-黑云母化；中期为石英-绢云母化；晚期为硅化、碳酸盐化和绿泥石、绿帘石化。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

The main characteristics include: the quiet Sun corona has a rapid response to the flare heating, within 2 second the corona temperature increases nearly one order of magnitude, but later such increase becomes very slowly; the downward velocity at early stage of impulsive phase is too small to be negnected; chromospheric evaporation made by conduction shows some intensely, the maximum evaporated velocity may be as large as 1000 km/s; the chromospheric condensation appears just when the chromospheric evaporation takes place and its place always coincide with that of transition region in the early stage; the maximum of chromospheric condensation occurs also in the early stage of impulsive phase, at which the density in condensation may be larger two order of magnitude than that of surround and the downward velocity may be as large as 100 km/s; after the maximum of chromospheric condensation, its strongth decreases gradually but its width becomes greater with time and have a tendency to transport into deep chromosphere; the front of chromospheric condensation heats atmosphere obviously and the temperature in the chromospheric condensation is higher than the original case; the downware velocity of transition region may be greater than 100 km/s at the early stage; when the evaporated material collide at the top of loop, the densityand the presure there increase rapidly, which result in the formation of a shock wave; and so on.

在改善色球辐射损失和精确分辨过渡区的基础上，通过联立求解连续性方程、动量方程和能量方程，构造了一维磁限制性耀斑环在热沉积作用下的大气动力学模型，获得了耀斑热模型下脉冲相早期较为细致的大气演化理论图象，其主要特征是：耀斑对宁静日冕的加热相当迅速，仅2秒钟日冕温度增加即达一个量级，之后日冕温度增加缓慢；脉冲相早期日冕向下速度很小，几乎可以忽略，热传导驱动色球蒸发，其过程较为激烈，蒸发极大速度可达到1000km/s；色球压缩区与色球蒸发几乎同时形成，且在早期其位置总是与过渡区位置重合；色球压缩极大发生在脉冲相早期，其时密度可高于周围约2个量级，向下速度可超过100km/s；色球压缩极大后，其强度逐渐减弱，但宽度明显增大，且渐渐脱离过渡区往色球传播；压缩区内物质温度要高于原先的大气温度；过渡区下降在脉冲相早期相当迅速，可超过100km/s；当蒸发物质在环顶高速相碰时，环顶的密度、压力迅速增大，且温度也有所增加，导致形成激波，其波面以每秒上百公里的速度自环顶向下传播；在脉冲相前期，日冕软x辐射对色球的加热作用可以忽略；等。

The result of fertilizer management of Sutian8 shows: what use the fertilizer of early stage handled, the plant height, ear height, stem thickness, leaf area etc. were better than early stage apparently, did not apply fertilizer to hand. Fertilized in lump sum on early stage, although expression was sent early for strong sprout, had also formed high-yield group, but later stage had the phenomenon of premature senility; Early stage did not be applied fertilizer, even if in late stage mend the fertilizer of equal quality could not also remedy. Corn ear output and quality would not raised unless the fertilizer applied at prophase (45%-60%), metaphase and anaphase had a certain proportion.

苏甜八号不同时期肥料运筹试验结果表明：施用前期肥的处理，无论是在株高、穗高、茎粗、叶面积等植株性状上，还是在果穗、产量性状上均显著优于前期不施肥的处理，前期一次性重施肥，虽表现为壮苗早发，也形成了丰产群体，但后期有早衰现象，前期不施肥，即使中后期补施同等数量的肥料也无法弥补因前期不施肥所造成摘要的影响，只有前、中、后按一定比例且适当提高前期肥的用量(45%一6006)才有利于提高鲜果穗产量和商品品质。
