( 3 ) towards the result of period estimation by the method called fluctuations of second order moments , we do some researches on period - searching , and find a basic method and another two universal methods 在该方法的基础上,增加约束条件得到了两种通用的周期搜索方法。另外,在周期同步方面,完成了一种在周期估计的基础上进行数据切割的周期同步方法研究。

By investigation on the relationship between period , quantity , extend of ostrinia furnacalis emergence and meteorological factors in qiqihaer , this paper analyzes the factors which effect on period , quantity , extend of ostrinia furnacalis about annual wave . the beginning time of ostrinia furnacalis pupae emergence depends on average temperature in may and june , weather conditions in july decide whether ostrinia furnacalis pupae finish ahead of time ; the beginning time of eclosion is decided by average lowest temperature and precipitation in may and june , and the end time of eclosion is decided by average lowest temperature in june and july , meantime , the length of time of ostrinia furnacalis eclosion and time of grub emergence influence on the extent of ostrinia furnacalis . an important condition of a great emergence of ostrinia furnacalis is that how temperature matchs humidity , which substantially result in reduction of maize output 本研究项目通过对齐齐哈尔市玉米螟发生期、发生量、发生程度与气象条件关系的分析,找出玉米螟发生期、发生量、发生程度年际波动的影响因子: 5 、 6月的平均气温决定了玉米螟化蛹开始的早晚, 7月的天气条件决定玉米螟化蛹是否提前结束; 5 、 6月的平均最低气温和降水则决定羽化开始的早晚, 6 、 7月的平均最低气温又决定了玉米螟羽化结束的早晚;而玉米螟羽化持续时间的长短和幼虫发生的早晚影响了玉米螟的发生程度;温湿条件配合适当与否是促使玉米螟大发生的重要条件,玉米螟大发生又会引起玉米的大幅度减产。
