Visual Rice Growth Models system represented an effort to design crop modeling software with object-oriented paradigm and to organize classes in system with model-document-view architecture. Firstly, the crop-environment system was abstracted as many subsystems and physiological processes with object-oriented paradigm while many classes were established to simulate the behaviors of these subsystems and physiological processes. In VRGM, the document-view architecture in Visual C++ was extended as model-document-view architecture for agricultural integrated system. In the model-document-view architecture, document gets the final simulation results by manipulating the models classes and acts as a communicating intermediacy between model and view. Views display the simulation results and translate users' operation and data entering to document. The architecture separates the domain models, data management and user interface.

Because source data is unsteadiness, the changes of data must be spread to materialized view and make it be consistency the changes of materialized view and source data. Otherwise the freshness of data in materialized view will be fall down and the authenticity and consistency of OLAP will be affected. For the maintenance problem of materialized view, an algorithm is presented and it can make the cost of materialized view recomputation be minimized.

由于源数据的不稳定性，其数据的变化必须及时传播到实体化视图中，以保持实体化视图与源数据的变化一致性，否则会降低实体化视图中数据的新鲜度，并影响联机分析处理查询结果的真实性和有效性，针对视图的维护问题，提出了实体化视图的一种维护算法，它将使视图重计算代价最小化。

When you present a view modally using the presentModalViewController:animated: method, the view controller animates the appearance of the view using the technique you specify.(You can specify the desired technique by setting the modalTransitionStyle property.) At the same time, the method creates a parent-child relationship between the current view controller and the modal view controller.

当你使用presentModalViewController：animated：这个方法来显示视图的状态，视图控制器将会用你定义的方法(你可以通过设定modalTransitionStyle 这个属性来设置你要的效果)来动画的显示出来，这个方法在当前视图控制器和模型视图控制器中创建了一个父子的关系。

Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础，通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析，发现：励磁故障是一个大干扰稳定性问题，励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异，已远非正弦曲线，因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想；异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆，它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆，但不能保证完全失磁之外的其它状态不会进入该阻抗圆，因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。
