Methods Uses the stochastic comparison the principle to divide into 84 example capillarity bronchitis trouble the treatment group and the control group.

采用随机对照的原则将84例毛细支气管炎患儿分为治疗组和对照组。

The research results show:(1) we combine time series method with the dispersed Markov Chains theory of stochastic process, and present a Markov Model based the time series analysis for predicting the precipitation for groundwater resources evaluation. Results show that the time series-Markov Model is efficient, and it has higher accuracy than that of the single model of time series;(2) started from the systematic point of view, we analyze the metabolic process of groundwater, establish the ultimate metabolic equation of groundwater for protecting the water resources, and discuss the value of reducing evaporation for making full use of the water resources;(3) Through a theoretical analysis of the results of the experiments, we draw a conclusion: the critical depth on evaporation of groundwater is in step with the height of the maximal capillary rise of media.

通过理论分析与实验研究，得出主要结论如下：(1)论文将传统的时间序列方法与随机过程马尔可夫预报模型相结合，以预报大气降水量，并用于地下水资源评价，创造性的提出了地下水资源评价中降水量的时序——马尔可夫预报模型；(2)论文从系统的观念出发，分析了地球水循环中地下水代谢过程，建立了旨在保护水资源的地下水极限代谢条件方程，并进一步阐明了减少蒸发量和增加补给量在水资源保护中的重要作用；(3)论文通过实验研究和理论分析，论证了潜水蒸发存在极限埋藏深度，得出了潜水蒸发极限埋深与介质最大毛管水上升高度一致的重要结论。

Secondly, by analyzing basic variables——stochastic cash flow and manager utility function, we gain a proposition (7. 1): If manager is risk averter, then he prefers low risk or riskless and he is satisfied with a basically constant compensation.

资本市场效率越高，企业的股票价格越能反映企业经营情况，因而企业发行股票也就更容易，加上代理人是普遍是避险型的，偏好于股权融资，这样企业的债务比率就会更趋于低负债的资本结构。

Each group of medicine stochastic use in the outpatient service spring the catarrh conjunctivitis patient, and enjoins patient one week later the subsequent visit.

将每组药物随机使用于门诊春季卡他性结膜炎患者，并嘱患者一周后复诊。

The following is a list of topics to be covered: index number approach (fixed basket approach, test approach, economic approach, stochastic approach, and Divisia approach), chain index and chained index, hedonic price index, macroeconomic price index, stock market price index, inflation measurement, and economic growth rate measurement.

本课程的主要内容包括：指数方法（指数的固定篮子方法、指数的检验方法、指数的经济方法、指数的随机方法、指数的 Divisia 方法）、环比指数与链式指数、 Hedonic 价格指数、宏观经济价格指数、证券市场价格指数、通货膨胀测度、经济增长率测度。

These stochastic bursting patterns are reproduced and explained by adding the term of noise to Chay model and the constructed map.

通过在Chay模型和构造的不连续映射中添加噪声项可以重复并且解释实验中的随机簇放电模式。

The bifurcation scenario was simulated by adjusting the relevant parameters in stochastic Chay model.

作者利用随机Chay模型更加逼真地仿真再现了实验所见的分岔序列。

The results showed that the statistical characteristics and changing regularity of the integer multiple spiking from the experiment were similar to those from the stochastic Chay model, but different obviously to those from the deterministic Wang model.

结果发现，实验和随机模型经随机自共振产生的整数倍峰放电节律具有相同的统计性质(峰峰间期越大，出现的频度越低，约呈指数递减)和变化规律，与确定性Wang模型产生的整数倍节律明显不同。

The experiments of neuronal pacemaker show typical bifurcations from period 1 to period 5 with stochastic bursting patterns. A discontinuous map of the slow variable in Chay model which captures the essential characters of the period-adding bifurcation scenario is constructed in this thesis.

在神经起步点实验中展示了伴有随机簇放电的从周期1到周期5的典型分岔，本文在把握加周期分岔的根本特征的基础上构造了Chay模型中慢变量的不连续映射。

The deterministic neuronal firing model could simulate only the period adding bifurcation scenario in which period n bursting was changed into period n+1 bursting directly. The period adding bifurcation scenario and the new firing pattern similar to the experiment could be simulated in the stochastic Chay model.

确定性神经放电理论模型只能模拟周期n节律直接到周期n+1节律的加周期分岔序列；而随机Chay模型可以模拟实验中的加周期分岔过程和新节律。

Diabetes is a social disease that affects several million people worldwide.
