The coarsened structure perpendicular to primary crack plane exhibits better propagation resistance than that parallel with primary crack plane, but it seems that crack propagation property at high temperature can not be improved by changing γ′precipitates morphology.

颗粒形态不会改变裂纹扩展路径及微观机制，粗化结构的疲劳裂纹扩展阻力随温度升高而降低的趋势比原始结构剧烈，同时与主裂纹面垂直的粗化结构具有比与主裂纹面平行的粗化结构更好的疲劳裂纹扩展抗力，但通过改变γ′形态似乎不能改善高温下裂纹扩展性能。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。

He also attempts to explore the way-out for African development by elaborating the changes in Igbo with the invasion of colonists and analyzing the tragedy of Igbo\'s disintegrationBy adopting post-colonial culture criticism, the author of the thesis attempts to analyze Achebe\'s shift of narrative point of view between an "insider" and an "outsider" and to explore his writing position in counterattacking the representation of Africa in western discourse and reconstructing the African image.

When the traditional nitrification-denitrification process is used for treating coking waste water, reflux nitrified liquid is required in anaerobic denitrification stage. Because of influence of the factors such as low carbon-nitrogen ratio and big reflux ratio, the denitrification rate is only 30%~50%.
