Some of the model was documented at the object level and occasionally at the field level, but there was no documentation on specific use cases.
一些模型有对象级文档，偶尔有字段级文档，但是没有关于特定用例的文档。
You can bind a model class to an XWT UI while, at the same time, the data field in the model object will be automatically fed to the UI controls.
可以将一个模型类绑定到一个XWTUI，而同时，模型对象中的数据字段会被自动地提供给UI控件。
In this case, instead of checking to see if the field was blank we could invoke a method on a model object to ensure that the current user wasn't already in the system.
在该例中，不是检查字段是否为空，我们可以调用模型对象的方法来确保当前用户已经不在系统中。
The model object for TimeEntry, which contains the information used for each time entry field, is shown in Listing 3.
清单3 中显示了 TimeEntry的模型对象（包含每个时间输入字段的信息）。
While I could model the notion of employment using a field in the Person type, that's a relational approach and doesn't fit well within the object-design scenario.
我会用Person类型中的一个字段来模拟雇佣的概念。这是一种关系方法，而且不太适合用于对象设计。
Data field of object describes model's state, operation field of object describes model's behaviors, and operations of model are responded by messages.
对象的数据域描述了模型的状态，其操作域反映模型的行为。而模型的操作是靠对象之间发送消息来响应的。
First, we regularize the attraction force field in the geometric active contour model to extend the capture range of the object boundaries, and improve the ability of convergence to the concavities.
首先，我们对几何活动轮廊模型中吸引力场进行正则化，扩大目标轮廊边缘对的轮廊曲线的吸引力范围，增加轮廊曲线搜寻凹轮廊的能力。
Traditional decoupling controlling comprehensive method is quit dependent on mathematical model of coupling object, so its application is limited in industry control field.
传统的解耦控制综合方法，对耦合对象的数学模型依赖性较大，因此限制了它在工业领域内的应用。
The type of spatial data model: the model based on object (element); network model; field model.
空间数据模型的类型：基于对象(要素)的模型；网络模型；场模型。
In order to implement easier, software programming model of object-oriented field bus application layer is stated.
为便于实现，提出了面向对象的现场总线应用层软件编制模型。
In the geology field, seeking a good data model for geo-data management become a hot issue to study for gis experts and geologists. Object-oriented digital geologic map data just cater to this demand.
在地学领域中，寻求一种更适合的数据模型已成为一种必然，面向对象的数字地质图数据模型的提出正是迎合了这一需求而产生的。
CyberCity often involves the modeling of Wide-field complex ground object of nature and humanity, especially difficulty in building the three-dimensional model which cover the whole city.
数码城市往往涉及大范围复杂的自然与人文地物建模，尤其困难的是建立覆盖整个城市范围的三维城市模型。
Each model has its advantages and limitations. Since both models are needed in application, we thus propose our object oriented model, which integrates field based and object based model.
由于许多应用中需要这两种模型，因此本文提出了我们自行设计的一种能够集成域和对象的面向对象空间数据库模型。
