查询词典 probability field

It is found that the probability density of quantum phase space strongly depends on the value of magnetic field and the energy level of charged particle, and the result is interpreted well by the Heisenberg uncertainty principle.

Because the genetic algorithm is a global stochastic searching method, and even if the defined fitness function is indifferential or uncontinuous, it is also possible to obtain the global optimal solution with a considerable probability. Thus there will be widely practical application in the engineering field.

由于遗传算法是一种全局随机搜索方法，即使定义的适应性函数不可导或不连续，它也可能以很大的概率求得全局最优解，因而在工程领域中将有十分广泛的实际应用前景。

Mosquitoes captured and the egg positive traps were counted and recorded every day. Results Comparing with the control group, yeast-generated CO2 could take a strong attraction to mosquitoes in the field (P.05), but had an adverse effect in laboratory. P. maximum infusion, tyre infusion and L-lactic acid dilution could not attract Aedes albopictus to oviposit in Mosq-ovitrap. The colour change of Mosq-ovitrap could not raise its attractant ability to mosquitoes, on the contrary, increase the probability of mosquito escaping from Mosq-ovitrap.

结果 实验室和现场的结果显示，酵母发酵产生的CO2在室内实验中没有增强诱蚊诱卵器的诱蚊效果，而在现场实验中却产生较好的诱蚊作用，实验组的诱蚊指数和诱蚊密度指数与对照组比较差异均有统计学意义(P.05)；大黍叶、轮胎浸出液和乳酸稀释液在试验中未显示出吸引白纹伊蚊雌蚊产卵的能力；在改变诱蚊诱卵器杯身颜色的试验中，杯身上2/3变为黑色并不能提高它的诱蚊和诱卵能力，反而增加成蚊逃逸的概率。

The author proposes the dynamic simulation model of marketing management system and a marketing mix effectiveness simulation system based on the research about theories and methods of management system simulation and marketing management. In the meanwhile, the author makes a detailed research of development trend of the simulation technology applied in marketing management, and deliberates the probability range about how to apply the three simulation technology in the field of marketing management in the future.

作者基于对管理系统模拟技术和市场营销管理理论与方法的研究，分别提出了企业市场营销管理系统的动态模拟模型，以及基于竞争者响应行为的营销策略组合效应的模拟模型，并研究了市场营销管理中模拟技术应用的发展趋势，探讨了三种新型模拟技术在市场营销管理领域应用的可能范围。

The results show that, under each drip irrigation treatment before the tasselling stage of spring maize, the fluctuation of average soil water content and soil matric potential at different soil depthes are comparative low under high frequency drip irrigation treatment, and the HDI can hold stable soil water content. The drip irrigation can obviously delay the effect of air temperature on the soil temperature, which was influenced by irrigation process, soil water content and crop growth stages. In addition, the irrigation frequency affects the spring maize root distribution in the soil, and the HDI improves the probability of root distribution in upper soil(0~40 cm). The yield difference of spring maize for irrigation frequency treatments is not significant under the typical field irrigation model combined irrigation with precipitation.

试验结果表明：在春玉米抽雄期以前阶段实施的滴灌各处理中，高频滴灌下土壤平均含水率和不同深度处的土壤基质势波动幅度较小，高频滴灌下土壤水分能保持在一个比较稳定的范围；土壤温度受灌水过程、土壤含水率及作物生育阶段的影响较明显，滴灌能显著延迟气温对土壤温度的影响；灌水频率对春玉米根系分布存在一定影响，高频灌溉能显著促进春玉米根系在上层土壤(0～40 cm)中的分布；此外，在这种典型的灌溉和降雨相结合灌溉模式下，不同灌水频率下玉米产量差异不显著。

Remember always that the bigger the bait, the probability of catching the big fish is better that having small baits.During summer, one bass fishing technique is choosing to fish along Long Point Bay at Lake Erie because during this time, the bass fishes especially the smallmouth bass fishes are swimming their way here back to the main lake after their spawning period.If you are an amateur in bass fishing, the best thing to do is to fish with a companion who is an expert in the field not only in fishing but also an expert in the flora and fauna of the river you are cruising or fishing of.As a beginner, you may opt to fish only in the shorelines of the lake or you may try fishing in the smaller lakes.

Chapter one of this text has recommended the foreign insurance to apply financial economy to the products pricing method of insurance company, but these methods have not explained how to determine the fair premium of the multiple-line insurance company .In order to solve many business line insurance company pricing problem, chapter two introduce an very important model in insurance company capital allocation field - MR capital allocation model, through deriving capital allocation formula and simulation analysis indicate MR model allocate multiple- line insurance company capital scientifically. In order to apply MR model to non-life insurance pricing, chapter three will extend MR model to introduce loss 3 and layer P . Since the premise of MR model is a certain market price of loss, the chapter four will use the risk-neutral probability transformation technique to get the market value of loss. Under lognormal distribution, we will use location parameter shift and proportional PH transformation to illuminate the technique. The final chapter combines the prior sections result to deduce out the fair premium formula, and apply it to price the catastrophe insurance.

本文的第一章介绍了国外保险业将财务经济学应用到保险公司产品定价的方法，但是这些方法都没有说明如何确定多业务线保险公司的公平保费；为了解决多业务线保险公司定价问题，第二章引入保险公司资本配置领域非常重要的一个模型—MR资本配置模型，通过推导资本配置公式及模拟分析表明MR模型科学地配置了多业务线公司的资本；为了将MR模型应用到非寿险公司的定价中去第三章扩展了MR模型，引入了损失β和层β的概念：由于MR模型的前提条件是有一个确定的损失市场价值，第四章利用风险中性转化方法获得损失的市场价值，在损失为对数正态分布的条件下，通过位置参数转化和比例危险转化方法给出了实例说明；第五章结合前几章的结果给出非寿险公司公平保费的定价公式，并运用它给出了巨灾保险价格的模拟分析。
