Element's type does not allow fixed or default value constraint.
元素的类型不允许使用固定值约束或默认值约束。
Since you can set any arbitrary attribute value (and yes, that includes values that you define) to a constraint expression or use it in a constraint, there are a lot of possibilities.
由于可以为约束表达式设置任何任意的属性值(包括您自己定义的值)，或者在约束中使用它，因此存在很多可能。
EB: What I have seen generally is constraint rules depending on a property value more than on the actual locale.
EB：我通常看到的是，约束规则对属性值的依赖要比对实际地区的依赖要多。
Try relaxing the value of each bounded constraint one at a time, solve the modified problem, and see what happens to the optimal value of the objective function.
一次只尝试放松每个边界约束一个单位，解决修改后的问题，看一下目标函数的优化值发生了什么变化。
A bounded constraint prevents the objective function from reaching a better value.
边界约束阻碍了目标函数达到更为优化的值。
Schedule might still be a fixed constraint, but then scope could be adjusted to deliver the highest value within the schedule constraint.
日程也许还是固定的约束，但是范围就得调整，以在日程约束之内交付最高的价值。
The second half of the report shows that the constraint is bounded and its marginal value is 1.
这个报告的第二部分说明这个约束是有界的，其边界值是1。
Each assertion creates a constraint object under the hood which evaluates the expected value against the actual value.
每个断言其实都在背后创建了一个约束对象，用来比较期待值和实际值。
Therefore, a relaxation of one unit in that constraint (an increment of one hour) would make the objective function's optimal value become better by the marginal value 1 and become 181.
因此，这个约束中放松一个单位（增加一个小时）可以使目标函数的优化值增加边界值1，成为 181。
If an XML validation check constraint exists on the XML column of the table, the user may need to validate the new XML value before the update either manually or by creating a trigger.
如果在表的xml列上存在XML验证检查约束，在手动更新或者通过触发器更新之前，用户可能需要验证新的xml值。
For example, if a before trigger supplies value to a NOT NULL column, then the before trigger is executed first and a value is supplied to the column so that the NOT NULL constraint isn't violated.
例如，如果一个BEFORE触发器给一个NOTnull列提供值，那么先执行BEFORE触发器，给列提供值，所以不会违反NOT NULL约束。
The itemNumber column provides a unique identity for each item (or row) and has an attached column-level constraint that enforces a valid value to always be supplied (NOT NULL).
itemNumber列提供了每个商品（或列）的惟一标识，它上面还有列级约束，强制要求提供正确的值（NOT NULL）。
The before trigger and check constraint on a table XML value always ensures that the XML values are valid as per the specified schema.
对一个表XML值应用before trigger和检查约束，往往可以确保 XML值对于指定模式是有效的。
Because the SchemaFactory is tied to a specific constraint model, you must supply this value at factory construction.
因为SchemaFactory是与具体的约束模型联系在一起的，所以必须在工厂构造的时候提供这个值。
Setting the value to once is useful if a constraint is static once initialized, as it will then only be evaluated once and increase efficiency.
如果一个约束在初始化之后一直是静态的，那么可以将这个值设为once，这样可以使约束只计算一次，可以提高效率。
Only the role field - the one that had a default value of user - passed the implicit nullable constraint.
只有role字段—其默认值为user—通过隐含的nullable约束。
A workaround to this is to supply a default value to the not NULL column whose value comes from a BEFORE INSERT TRIGGER, so that the constraint is not violated.
一种解决方法是给从BEFORE INSERT触发器取得值的NOT null列提供默认值，这样就不会违反约束。
In other words, a change in x2 won't change the objective function's value, given that the constraint holds for the new (x1, x2) pair.
换而言之，当约束使用新的(x 1,x2)对时，x2的变化不会引起目标函数值的变化。
And here you can see another constraint that USES the two registers % eax and % edx to combine two 32-bit values and generate a 64-bit value.
在下面可以看到另一个约束，它使用两个寄存器%eax和%edx将两个32位的值合并在一起，然后生成一个64位的值。
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.
对于Laszlo中的任何属性，都可以为之赋予一个约束表达式(constraintexpression)，而不是赋予一个标准的值。
If when is omitted, then the value defaults to always, which implies that every time a dependency of ContrainedExpression changes, the constraint will be reevaluated.
如果忽略了when，那么这个值就默认为always，也就是说，每当ContrainedExpression的一个依赖关系发生改变，该约束都将重新计算。
Unpredictability is also a major constraint for companies and countries trying to diversify into higher value production.
不可预见性也是限制各公司和各国从事多种高附加值生产的一个主要因素。
The cell string type further defines the cell by enforcing the constraint that a cell can only contain a value of 1 through 9 and a period.
单元格字符串类型进一步定义单元格，把其中的值限制为1到9的值和点号。
The other value, immediately, can be used to evaluate the constraint when the enclosing element is defined and the constraint does not depend on other objects.
另一个值是 immediately，如果定义了结束元素，并且约束不依赖于其他对象，那么可以使用这个值来计算约束。
In the paper, it provides the geometrical solution to extreme value of many variables function by geometric properties of objective function or constraint condition.
本文中，利用目标函数或约束条件的几何性质，提供了某些多元函数极值或最值问题的几何解法。
For example, a constraint of the maximum value of a day field within an element representing a date would depend on the month, and even year, fields.
例如，对表示日期元素中的day字段的最大值的约束取决于month、甚至是year字段。
The dmoType attribute value for hosting requirements, specifies the constraint to a type of capability.
这个托管需求的dmotype属性确定了对性能类型的限制。
Now you set the store ID and supplier ID fields so that they do not accept an empty value. Of course, you can add a schema constraint into the XForms model to achieve this.
现在，设置storeID和supplier ID字段以使这两个字段不接受空值。
It represent in the model setup with the linear complete transfer and the minimum risk of loans portfolio as the target function and the constraint of earning yield risk value.
具体表现为运用线性完备变换方法，以贷款组合风险最小为目标函数，以贷款组合期望收益率为约束条件建立模型。
The schema constraint count(key('ids', .)) = 1 checks the set of all identifiers to be sure that only one has the current value (in other words whether the identifier is unique).
模式将限定count(key('ids',.) ) =1检查所有的标识符，从而确保只有一个包含当前值（换句话说，确定该标识符是否是惟一的）。
