当然，我们可以完全不使用显式的范围，只要能确保没有用不适当的类型来实例化类型参数。
Of course, we could simply leave off the explicit bound and just make sure that we never instantiate the type parameter with an inappropriate type.
XSLTv2的新特性之一就是为您的变量和参数提供显式数据类型的能力。
One new feature of XSLT v2 is the ability to provide an explicit data type for your variables and parameters.
一旦声明了类型，就可以将该类型显式的作为第一个参数来声明函数。
Once a type has been declared, functions can be declared which take that type as an implicit first parameter.
JBoss没有显式地绑定Account参数，而是提供了对当前正在执行的对象的反射访问，因此需要把类型转换到对应的类型。
Rather than binding the Account parameter explicitly, JBoss provides reflective access to currently executing objects, requiring a cast to the corresponding type.
Scala通常可以推断出方法的返回值（但是方法参数的类型就不行了），所以我们不用显式声明。
Scala can usually infer the return type of the method (but not the types of the method arguments), so we drop the explicit declaration.
当要将某个模板类型参数用作基类列表中的模板参数时，必须显式地将该模板类型参数添加到模板类名中。
You must explicitly add the template type parameters to the template class name when using it as a template parameter in a base class list.
没有显式类型参数时，会使用类型推理来确定函数的参数类型。
When there are no explicit type parameters, type inference is used to determine the types of parameters of functions.
