The germination rate of sclerotia increased with temperature rose, mathematical relation of germination rate and temperature were set up 首次报道了不同生境下菌核能在土层下侵染水稻表现典型病斑。
This dissertation analyzes the causations of noncoherence, develops the concrete mathematical relation between sparse-band radar signatures and presents a method to compensate the lack of mutual coherence . the simulation results show that this method is effective 各雷达互不相干是制约融合处理的主要难点,本文详细分析了其产生原因,并推演了各雷达信号之间的具体数学关系,提出了一种相干补偿的方法,仿真实验结果表明该方法是有效的。
Based on the data of daily water withdrawal, rainfall and evaporation in 14 experimental paddy fields, which were varied in landform, soil type, drainage system, growth rule, and irrigation mode, with typical investigation, and analysis in the influence factors on water use, the research of water use regulation in paddy fields and its influence on water resources distribution was done . at the same time, the mathematical relation between the total water consumption and the growth days of paddy was founded 以2001年为基准年,通过对杭州市不同地形、不同土壤、不同渠系、不同种植制度、不同灌溉方式的典型水稻田灌水的逐日记录,结合降雨、蒸发监测值,实测了不同水稻田的灌溉水量及水资源使用量,并结合典型调查,分析了影响本地水稻用水的各因素的影响程度,研究了本地水稻的用水规律对本地水资源配置的影响。
From the qualitative point of view, the writer issued the problems and methods that should be noticed in the choice of equipment and the configuration in quantity . in quantitative study, the main task was to obtain the reasonable quantity of devices . two different quantitative methods, comprehensive cost model in the stage of port planning and a formula that could present the mathematical relation of possessed equipment amount, the efficiency of equipment in good condition and amount of equipment on duty, were employed in this research stage 在这一阶段,作者采用了两种不同的定量研究方法来进行讨论:在码头的投资规划期,采用了综合成本模型来确定港机的合理投资规模;在营运期,通过拟合模型中的参数,建立设备完好率、港机拥有量和设备最佳出勤台数三者之间的函数关系式,来计算港机的最佳拥有量。
At first, regarding niches and biological communities as basic elements, this paper studies the niche theory, marginal effects of ecosystems, the principle of fuzzy mathematical relation between niche and community, proposing similar prior choice competitive principle, the choice of niches between species and competitive and evolving principle, and verifying guass competition theorem 首先,以生态位(niche)和生物群落为基本单元,抽象研究了生态位理论、生态系统的边缘效应、建立了生态位与群落的模糊数学关系原理。提出了相似优先选择竞争原理、物种间生态位的选择、竞争及演化原理,证明了高斯竞争定理。
