观测的

In order to make a better study of the collection and utilization of rainfall so as to achieve the spatial and temporal redistribution of precipitation, the experiment adopted the method of fixed point observation and observed the outcomes by different surface processing techniques.

采取定位观测的方法，在山西省岚县香沟小流域研究集雨场的规划设计，地表处理技术，观测其集流量和集流效率，并对梯田作物有无补灌措施的生产效益进行对比试验研究。

Each model consists of a Hidden Markov process and an observation process.

它包括一个不被直接观测的马尔可夫过程和一个与之相关的可观测过程。

System observability is examined and two necessary conditions for the system to be observable are obtained.

首先分析了系统的观测性，得出了系统可观测的两个必要条件。

According to two factors between the observability and the stability in the paper, a practical phasor measurement unit configuration scheme based on weak voltage area surveillance and incomplete observability is proposed.

本文同时考虑系统可观测性和电压稳定性两方面因素，提出了一种基于电压薄弱区域监视的非完全可观测的同步相量测量单元配置方案。

The supply chain coordination with sales effort effects is explored. This work designs a contract to coordinate the supply chain in case of observable sales effort; it proves that the usual contracts can never coordinate the supply chain, but a modified scheme can improve the performance of the whole system in term of inobservable sales effort.

分析了进取型供需链的协调问题，如果促销行为是相互可观测的，设计了一种特殊合同策略来协调该系统，如果促销行为相互不可观测，则证明了常见合同策略无法完全使系统达到协调，但适当的设计可以改善系统性能。

In this paper, authors research the so called PSSVM which uses the polynomial functions to smoothen the objective function and present two polynomial functions.

引 言研究从观测数据出发寻找规律，利用这些规律对未来数据或无法观测的数据进行预测的工作，迄今为止，还没有一种被大家共同接受的理论框架。

With an example, its calculation results were compared with the observation results. The conclusions suggest that this model accords with the actual traffic flow condition at the unsignalized intersection.

通过与实际观测的支路行车延误对比分析，模型计算结果与观测的延误值接近，表明该模型较为符合公路无信号控制交叉口的实际情况。

The other one retrieves vertical velocity from the reflectivity using statistical algorithm and assimilates the vertical velocity taking Richardson's equation as observational operator. It is found that the vertical velo city derived by the former is usually too weak while the later gets the distinct three dimensional convective structure of meso-scale system with strong vertical velocity.

其一是采用Richardson方程通过水平风场、温度和气压来对垂直速度进行诊断，其二是利用统计方法由观测的反射率因子反演出垂直速度后，再采用Richardson方程作为观测算子对反演的垂直速度进行同化。

The sky brightness and the extinction coefficient in .

综述对丽江高美古的视宁度、天光亮度、消光系数进行观测的原理、仪器、观测方法和结果。

I noted no astigmatism, and no issues with pinch or cooldown (things that seem endemic with medium level refractors these days).

我在观测的时候没发现有散光现象，压力和降温对观测也没有什么影响（现在只有个别中等水平的折射望远镜才会存在这类问题）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
