| 1. | In the rural the naturally matured tomatoes lhaveq this nature 在乡?伦匀怀墒斓姆?丫哂姓庵中灾? |
| 2. | Soil water storage decreased on the whole in summer and autumn during drought year , but increased during rainy year 干早年,夏秋以失墒为主,土壤水分处于负补偿;丰水年,夏秋以增墒为主,土壤水分处于正补偿。 |
| 3. | By using this system the soil moisture content in beijing can be monitored and the distribution map and the isoline chart of soil moisture content can be plotted in time 同时,系统还可利用增退墒模型、人工神经网络模型和时间序列模型进行土壤墒情预测和预报。 |
| 4. | In the mathematic calculation , adopt ansys software , get four representative thermal bridges " internal temperature distribution and heat - flux get through the thermal bridge and the around outer wall 在数值计算中,采用ansys软件,求出了4种典型热桥的内部温度分布及通过热桥和周围外墒的热流量。 |
| 5. | The proper cultivation measures to reduce the quantity of the pathogen include sowing on suitable date , reasonable density , water quantity and fertilizer combination and avoiding highly susceptible cultivars , etc 适期播种、合理密植、视墒灌水、配方施肥、培育小麦壮苗及避免种植高感品种等均能减轻小麦秋苗带菌量。 |
| 6. | The image is divided into a number of sub blocks , each with its associated color histogram and image entropy . theoretics and experimental results show that the techniques can help to make similarity matching more precise . 4 多精度色彩匹配将图象划分成了许多子图块,每一子图都具有其相应的色彩直方图与图象墒,作为细粒度匹配的基础。 |
| 7. | Conclusion shows that in autumn precipitation profusion , soil moisture abundance , winter air temperature on the high side , the year of precipitation distinctness lack , adopt live through the winter plastic pellicle mantle can holding soil reservoir sluice maximum 结论认为:在秋季降水充沛、土壤收墒充足、冬季气温偏高、降水明显偏少的年型,采取越冬覆盖能最大限度保持土壤水库蓄水。 |
| 8. | We evaluate the statistical visibility of information hiding algorithms based on the coefficient of kurtosis , differential entropy , goodness of fit test and kullback entropy . on these bases some methodologies are suggested to defend against statistical steganalysis 重点研究了含密序列统计可见性的定量评估,提出了基于峰度系数和微分墒的偏态评估、基于拟和优度检验的统计可见性评估和基于鉴别信息的统计可见性评估。 |
| 9. | Based on rainfall and evaporation amount , the change of soil water could be divided into three main periods , such as decreasing of soil water storage in spring , alternatively decreasing and increasing in summer and autumn , and relatively stable in winter 根陈洪松博士学位论文:黄土区坡地土壤水分运动与转化试验研究据年内降雨和水面蒸发量的相对大小,可将土壤水分的变化分为三个主要时期:春季失墒期、夏秋增失交替期和冬季相对稳定期。 |
| 10. | The modified zndx in comparison with others is well indicative of the severity and extent of flood / drought event and of more objective classification of them , which is therefore quite applicable to a extended area . ( 3 ) the main anomaly structures of grades of drought / food in summer over northwest china present pluvial pattern and dry pattern in all the areas , and spatial changes are opposite pattern from the noth to the south and the west to the east . the first four rotated loading vector fields represent four principal precipitation anomaly areas : the weishui river basin , east of the qinghai - xizang plateau 但修订过的zndx指数根据气温、土壤湿度及前期气候湿润度等因子能够客观的反映出西北地区的旱涝特征。 ( 3 )西北地区季与年区域旱涝等级表明:西北地区的干旱雨涝有显著的阶段性和年际变化特征。 1980 ’ s到1990 ’ s中期,气候较湿润,土壤湿度增墒较明显; 1990 ’ s中期以后是40年干旱最异常的时段; 1960 ’ s旱涝交替发生,旱涝趋势接近常年; 1970 ’ s气候虽干旱,但没有1990 ’ s中后期显著。 |
