它由包含可变类型的属性的活动来实现，其中类型会根据其他活动设置而变化。
It is implemented by activities that contain a property of variable type, where the type can vary depending on other activity Settings.
不像字符串是不可变量，列表是可变类型，例如：它可以改变它本身某个元素的值。
Unlike strings, which are immutable, lists are a mutable type, i. e. it is possible to change their content.
一个类型的复杂性指示了你应该使用这三个策略里面的哪一个来初始化不可变类型。
The complexity of a type dictates which of three strategies you will use to initialize your immutable type.
当我们分析某个地区内的土壤多样性时，我们是在测量土壤属性的可变性，以及在某个特定地区有多少不同的土壤类型。
When we analyze pedodiversity within an area, we are measuring how much variability there is in soil properties and how many different types of soil there are in a particular area.
常量池中各项的长度是可变的，每项的第一个字节标识项的类型以及对它解码的方式。
Items in the constant pool are variable length, with the first byte of each item identifying the type of item and how it should be decoded.
如何定义具有数量可变的参数(每个参数的类型可能不同)的模板化类或函数？
How do you define a templated class or a function with a variable number of arguments, each with a potentially different type?
目前这个提供程序支持主机变量、模块、ARRAY数据类型、复合语句和可变长度时间戳。
This provider now supports host variables, modules, the ARRAY data type, compound statements, and variable length timestamps.
那我们接下来要去学习一些可变的类型，我们以一个可能你们大多数人。
Well now we're going to talk about some mutable types. Things you can change.
首先调用f的模板化版本，第一个参数的类型是字符串，作为大小可变的参数提供字符和双精度值。
The first time around, the templated version of f is called, with a string as the first argument type, and the character and double are packed off as the variable size argument.
我们也可以使用val和一个可变的类型，比如ListBuffer。
We could have used a val with a mutable type, like ListBuffer.
很显然，这种方法很糟糕，但是解决方法也很简单：永远不要将可变对象类型用作hashmap中的键。
Clearly, this approach is a pain but the solution is easy: Never use a mutable object type as a key in a HashMap.
但是发掘这些有用之物可能有点复杂，比如只要您不将可变对象类型作为键，您就可以用自己的方式使用 HashMap。
Unearthing tidbits often involves some complexity, however, like discovering that you can have your way with HashMap, just as long as you never use a mutable object type as its key.
any自己描述的数据类型，可表示任何idl类型可变化。
Any Self-describing data type that can represent any IDL type variable.
list是异构可变容器，这意味着它可以存放不同类型的对象且创建后可以修改。
The list is a heterogeneous mutable container, which means it can hold different types of objects and can be modified after it has been created.
如果只希望为已有的信息类型增加一些新的可变结构，应使用领域专门化而不是主题专门化(请参阅参考资料中的“Specializingdomainsin DITA”)。
If you truly just want to add some new variant structures to an existing information type, use domain specialization instead of topic specialization (see "Specializing domains in DITA" in Resources).
这些类型是不可变的，就是说整数对象一旦创建，其值便不可更改。
These types are immutable, which means that when an integer object is created, its value cannot be changed.
下面的表2简要的概述了这三种可变性类型。
These three types of variability are briefly described in Table 2 below.
如文中所述，tuple类型是不可变的异构容器。
As discussed, the tuple type is an immutable heterogeneous container.
容器类型间的另一个不同点来自于它们所持有的数据的特性，下面四种容器类型的顺序是不可变的。
Another difference between the container types results from the nature of the data they hold. The following four container types are immutable sequences.
就像tuple一样，list也可以持有不同类型的数据(或不同类型的对象)，这就是我所说的异构的可变序列。
And just like a tuple, a list can hold different types of data (or different types of objects). This is what I mean by a heterogeneous mutable sequence.
例如，tuple类型，尽管它是不可变的，灵活性较差，但在同一环境中使用时，它们通常比list类型快得多。
For example, the tuple type, while less flexible because it's immutable, is generally much faster than the list type when used in identical situations.
而VB却同时支持可变和不可变的匿名类型，对于这两种匿名类型，实现和使用的规则也略有不同。
VB allows both mutable and immutable anonymous types, with subtly different rules for each.
本文介绍一个新的序列类型：list，这是一个可变的序列类型，并演示以多种不同方法使用它。
This article introduces a new sequence type: the list, which is a mutable sequence type that demonstrates a number of different ways it can be used.
本系列的第三篇文章探索Python类型的层次结构 —— 使用字符串介绍了 Python string，这也是一个不可变的序列，但仅针对字符数据。
The third article in this series, " Exploring the Python type hierarchy, Introducing Strings," introduces the Python string, which is also an immutable sequence, but only for character data.
干细胞是可变的，意味着它们可以变成其他任一类型的细胞。
Stem cells are transmutable, meaning they can be turned into any type of cell.
最后的建议是关于保护敏感数据的，就是要避免使用不可变的数据类型，比如string。
The last advice on protecting sensitive data is to avoid using immutable data types like String.
