| 5. | Its developmental zero was 11 . 01 , and effective temperature constant for one generation was 791 . 27 day - degrees 天敌主要有红点唇瓢虫、草蛉、蜘蛛、捕食螨以及刺粉虱黑蜂、黄色跳小蜂等。 |
| 6. | Based on the effective temperature accumulation above 12 and variety maturity characters , physiological time for predicting the development processes from sowing to boil opening under different environments was determined 以12的有效积温和品种熟性因子为基础,建立了一种统一的生理时间尺度,可预测不同环境条件下不同品种从播种到吐絮的全过程。 |
| 7. | The scheme greatly simplifies the numerical calculation and enables to give an effective temperature prediction on the sites where electronic elements are located , which offers a parctical method for both the performance evaluation and the structure optimization of cooling - plate 模型大大简化了数值计算,并能有效地预测电子元件安装部位的板面温度,这为评价冷板性能、优化冷板设计方案提供了一种有效的分析手段。 |
| 8. | The relation between stellar chromospheric activity and rotation of evolution stars have a good relativity . but meticulous analysis show chromospheric activity of evolution stars depend on stellar spectral type and effective temperature strongly . we provide several possible explain for those phenomena 但是细致分析显示演化恒星色球活动水平随恒星自转周期间的分布对恒星光谱型和恒星表面有效温度有很强的依赖,并对这些现象提出了几种可能的解释。 |
| 9. | Make the theoretical and experimental research of self - cleanup , through the experimental research to the tin , we get the conclusions of jointed cold - blowing and hot - blowing period and the effective temperature range etc . proposed the practical measures to improve the effect of the self - cleanup , laid the groundwork for the future further in - depth study and application 通过对蓄冷器的实验研究,掌握了冷吹期和热吹期的温度变化规律,获得了热吹期填料温度闭合和输出气流有效温度范围等结论。通过自清除原理的分析和自清除过程的实验,提出了改善自清除效果的实用措施,为今后进一步深入研究和应用打下了基础。 |
| 10. | The sub - model for design of population density was developed according to the principle of determining boll number from target yield , fruit node from boll number , fruit branch from fruit node and population density from fruit branch by integrating the effects of sowing date , cutout date , effective temperature accumulation above 12 , variety type , and fertilizer and water management levels . sowing rate was then decided by integrating the effects of different soil water and salt contents , ph , temperature and sowing style on seedling emergence rate with relative weight method 基于“以产定铃、以铃定节、以节定枝、以枝定苗”的原理,同时考虑播种日期、打顶日期、 12的有效积温、品种株型特性、肥水管理水平差异等因素来确定适宜的种植密度;在此基础上,应用相对权重法计算土壤含水量、含盐量以及整地质量和播种方式等多个生态环境因子对出苗率的综合影响,进而确定播种量。 |
