更新模型值；处理事件。
由于验证发生在组件值绑定到模型之前(在更新模型值阶段)，所以模型处于未知状态。
Because validation occurs before the component values are bound to the model (in the update model values phase), the model is in an unknown state.
若表单是自动保存的，请求处理生命周期的这后三个阶段（更新模型值、调用应用程序和呈现响应）是不必要的。
The last three phases of the request processing life cycle (Update Model Values, Invoke Application, and Render Response) are not needed when the form is auto-saved.
在更新模型值的阶段中，会使用保存在GUI组件中的经过转换和有效性验证的值来调用CD的赋值方法。
In the update model values phase, the setter methods on the CD are invoked with the converted and validated values stored in the GUI components.
由于这个示例程序并没有与组件关联任何有效性验证规则(在下一篇文章中我们将介绍这种特性)，因此您可以继续进入更新模型值的阶段了。
Since this example application doesn't have validators associated with the components (I'll introduce this feature in the next article), you'll simply advance to the update model values phase.
然后，控制器可以决定用该数据更新模型的主实例，或者根据这些值采取某种操作。
The controller can then decide to update the primary instance of the model with this data or take some action based on these values.
另外，您不想直接从视图中更新模型的current _ card值。
You also don't want to update the model's current_card value directly from the view.
这是一个重要的模型。当进程A自己更新一个数据项之后，它总是访问到更新过的值，绝不会看到旧值。
This is an important model where process a after it has updated a data item always accesses the updated value and never will see an older value.
当设置了延迟时，直到用户在指定的时间段内不再做变更，更新的值才会推给模型。
When a delay is set the updated value isn’t pushed until the user stops making changes for indicated time span. Pete offers a couple of examples including
为了根据实际工况实时优化各子过程设定值，必须利用实际测量数据动态更新产品质量模型。
The quality model should be constructed and updated based on the new data from the real process in order to optimize the set point of each sub-process dynamically.
利用巴特查理亚距离描述粒子与目标颜色模型的相似性，作为粒子更新权值的有力依据。
Furthermore, Bhattacharyya distance is employed to estimate the similarity between the target model and each hypotheses of the particle filter.
在模型更新阶段，组件的值将被复制到对应的组件当中。
During the Update model phase, component values are copied to the component's model object.
对像素值属于多个分布模型的情况，用最小相似距离确定要更新的模型。
When a pixel could be represented by more than one distribution model, the model which has the minimum similarity distance was updated.
另外，模型对网络的初始化和运行过程，以及节点间进行交互时的资源查找，信任值查询、更新等算法进行了较为详尽的描述。
The initialization and operation process and the resource searching, trust querying and updating algorithm are also thoroughly described in the model.
