According to statistical and survey data at provincial levels, trend of Grain per unit area yield materials and its influencing forces in Northern Anhui Province during the last 20 years were discussed in this article. It was found that: since 1991, the total Grain per unit area yield materials availability took on increasing, but regional difference was very obvious in Northern Anhui Province;Suzhou City and Huaibei City with higher rate took on increasing as a whole, inverse to the lower Grain per unit area yield materials in Fuyang City, Bengbu City and Huaian City. Grey correlation analysis showed that the most important factors of Grain per unit area yield materials were the effective irrigated area, net income of farmer per capita and financial support to agriculture. However, the influence of natural disaster and pesticide application amount should not be ignored.

The control system has become more and more complex with an increasing demanding of dependability. Sometimes we want to know whether the system is what exactly we want. The use of formal modeling methods and refinement shows a great potential in solving this problem. In this paper, we proposed an modeling method for control system based on Event-B. Through preprocessing of requirements we can facilitate and guide our modeling. With Rodin platform we instantiate the method using the landing gear control system. The use of invariants as safety constraints and animation helps to complete the verification process. This method not only makes formal modeling easy and approachable, but also helps us find some of the missing requirements.
