For any attribute in Laszlo, you can assign a constraint expression instead of a standard value. Constraint expressions begin with a dollar sign, and have the following format.

A common example is a co-occurrence constraint, where the constraint on one part of a document depends on another.
一个常见示例就是同现约束(co - occurrence constraints)，在这种情况中，文档某部分的约束取决于其他部分。

接下来的三个图展示如何添加安全性约束（图8），如何设置正确的URL和HTTP方法（图9）以及如何针对该约束允许“DADXUser”角色（图10）。
To drop the foreign key constraint with index disabled and recreate this referential constraint, issue the following command
要终止索引禁用的外键约束，重新创建这个参考约束，执行以下命令
We opted for a generic "requires and provides" style constraint system but the really cool part is the pseudo-boolean constraint engine, SAT4J, we use for selecting components to build a system.
我们选择了通常使用的“请求和供给”形式来约束系统，但最酷的部分还是伪布尔约束引擎（pseudo-boolean constraint engine）——SAT4J，我们用它选择组件来构建系统。
A class level constraint has access to the bean instance rather than one of its properties and applies some constraint logic based on several properties.
类级别的约束能获取Bean实例，而不是它的某一属性，还能应用一些基于若干属性的约束。
We added a constraint in our Speaker entity that age should be between 25 and 60, but the test suite does not take that constraint into consideration.
我们在Speaker实体中加入一个约束，年龄应在25到60之间，但测试套件对此约束不予考虑。
This tells GLPK to create a constraint for each toy type in TOY, and the equation that will rule each constraint will be what comes after the :. In this case, GLPK will create
这告诉GLPK为 TOY 中的每种玩具类型都创建一个约束，每个约束的等式都在 : 之后出现。
Each constraint has a variety of meta-data associated with it. The following attributes are used to define a constraint.
每个约束有与之关联的不同元数据。
The web.xml file for the servlet contains a <security-constraint> element that defines the security constraint, the HTTP methods that it applies to, and the roles that use the constraint.
servlet的web.xml文件包含一个 <security-constraint>元素，该元素定义安全性约束、它应用的HTTP方法以及使用该约束的角色。
In Oracle 10g, if there is a BEFORE INSERT TRIGGER and a NOT NULL constraint on a table, then the BEFORE TRIGGER is executed first, and then the constraint check is performed.
在Oracle10g中，如果表上同时存在BEFORE INSERT触发器和NOT NULL约束，那么先执行BEFORE触发器，然后执行约束检查。
The source pointer SRC is put into % esi by using the "s" constraint, and the destination pointer DST is put into % edi using the "d" constraint.
通过使用“s ”约束将源指针src放入%esi中，使用“d ”约束将目的指针dst放入%edi中。

位置优先原则：在判断浮动框位置时，最佳垂直限制优于最佳水平限制。
OK, and we can find this one from the constraints as we've een at the beginning either by differentiating the constraint, or by using the chain rule on the constraint.
我们可以从限制条件中找到这个，我们一开始就看到的，要么用微分限制条件，要么利用链式法则。
The constraint is the constraint of the experiment and the constraint of the experiment is that the enthalpy is constant. So the constraints we have here, is the constant enthalpy.
这个实验的限制，就是焓是常量，所以这里的限制是焓不变，我们考虑的这个过程。
