Heat - sink and Package datum , Pad Spacing, Gap , Length, Width, Spread, Tweeze , Missing, Broken or Un - plated Pad.
在面向对象技术中，对象能在单个实体中封装数据和操作(方法)，并为知识和被模拟领域中的实体的表示提供条件。
With the object-oriented technology, an object is a single entity in which data and methods are capsulized. It can be used to represent knowledge or entities in simulated domain.
因此，提供程序是指任何一个实现OLEDB接口来封装数据访问并将其向其他对象(即，使用者)公开的软件组件。
Thus, a provider is any software component that implements OLE DB interfaces to encapsulate access to data and expose it to other objects (that is, consumers).
绑定封装所有配置和策略数据，使应用程序无需处理这些细节。
Bindings encapsulate all the configuration and policy data, thereby insulating the application from these details.
这些应用程序必须能够生成一系列事件(其中封装业务数据)，并将其转发到公共事件基础结构(CEI)。
These applications must be able to generate a series of events, which encapsulate the business data, and forward them to the common event infrastructure (CEI).
使用这种方法，您可以利用由应用程序暴露的应用程序编程接口(API)来访问旧系统封装的数据和功能。
With this approach, you leverage the application programming interfaces (APIs) exposed by your applications to access both the data and the functionality encapsulated by legacy systems.
就像任何其他机器一样，软件应用程序期望获得某些“原料”，例如数字列表、XML模式中封装的数据或者协议。
Just like any other machine, a software application expects certain raw materials, such as a list of Numbers, data encapsulated in an XML schema, or a protocol.
由于它基于相关的行为对服务进行分组，而不是进行封装(行为及数据)，所以这组服务与业务对象略有不同。
Since it groups services on the basis of related behavior, rather than encapsulated (behavior plus data), the set of services will be subtly different from a business object model.
我个人倾向于将所有的数据访问逻辑封装到这个类中。
Personally I like the idea of keeping all the data access logic encapsulated in that class.
