A study on relationship between occurrence of ostrinia furnacalis and meteorolgical conditions 齐齐哈尔市玉米螟发生量的预测预报
It is because that there are too many effective factors , which are uncertain 这是由于影响害虫发生量的因素较多及其不确定性所致。
The conclusion provided basis for the forecast of amount of the pests after forest fire 该结论可为火灾之后虫害发生量的预测提供依据。
The applicability to the occurrence volume of condensation water is strong , can be discharged not only intermittently , but also continuously 对凝结水的发生量适用性强,既可间歇排放,又可连续排放。
