| 1. | Ozone generation rate mg h
臭氧发生量mg h |
| 2. | 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 |
| 3. | 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。 |
| 4. | 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。 |
| 5. | 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。 |
| 6. | The prediction of the occurrence level of pests is to predict the amount of pests and it is the core of which and how many fields need to be controlled
发生量预测就是预测害虫的发生数量，害虫发生量的预测是决定防治区域、防治田块面积及防治次数的依据。 |
| 7. | So we propose a there - layer bp neural network that can better depict the model ' s feature of complex nonlinear , multi - input - output and indefinite . neural network are composed of simple elements operating in parallel
因而采用三层bp网络对虫害发生量进行预测可以有效的刻画其具有的不确定、多输入、复杂的非线性特征。 |
| 8. | Owing to the controlling of crab to the rice planthopper , the number of rice planthopper was obviously less than that of the control paddies without used pestcide , and in general years , the rice planthopper can be controlled by cultural crab and without appling pestcide
由于螃蟹对稻飞虱的控制作用，养蟹稻田稻飞虱的发生量比不施药对照田明显偏低，一般发生年份，不用药防治，即可控制稻飞虱的为害。 |
| 9. | General speaking , the different urban layout form property and intensity determine the different traffic need and also decide the traffic generating volume sucking volume and layout form . in some degree , those factor also determine the traffic structure
一般来说，不同的土地利用布局、不同的土地利用性质和不同的土地利用强度，对应着不同的交通需求，决定了不同的交通发生量和交通吸引量、交通分布形态，在一定程度上也决定了交通结构。 |
| 10. | Based on above analysis , using statistical method such as similar regression step by step , the quantitative model and qualitative model for date quantity and extent of ostrinia furnacalis forecasting were developed . by research the relationship among date , quantity and extent of ostrinia furnacalis and yield of maize , the estimated model of loss that yield of maize was effected by date , quantity and extent of ostrinia furnacalis was developed . the forecasting result was satisfactory after predicting
在分析玉米螟发生期、发生量、发生程度与气象条件关系的基础上，运用聚类分析、相似分析、逐步回归等统计分析方法建立玉米螟发生期、发生量、发生程度的定性、定量预报模式，又通过对玉米螟发生期、发生量、发生程度与玉米产量关系的研究，得出玉米产量受玉米螟发生期、发生量、发生程度影响的损失估计模型。 |
