在真实世界里，对一个联系人来说“最近修改时间”可能没有什么真正的意义，而只是一个模型在系统中怎样被使用、跟踪、持久化的功能而已。
The modified date has no real meaning for a contact in the real world, but is a function of how the model is used, tracked, and persisted in the system.
而且任何优秀的SDK都会带一个手机操作系统的模拟器，这样开发者在电脑上就可以测试软件，而不一定要真正安装到手机上。
And any good SDK comes with an emulator for the OS itself, so devs can test apps without actually installing them on a phone. Apple's got one, but it only works on Macs.
正如所说的，合成驱动不同于模拟驱动在于它能意识到操作系统，有了这种新的意识，操作系统可以把它的驱动模式从一个严格而缓慢的模拟方式转变为一种我称之为和真正的驱动“握手”过程或一种桌面快捷方式。
With this new awareness, the operating system can change its driver mode from one of strict and slow emulation to what I call a "handshaking" process with the real driver or a desktop shortcut.
而且传统的虚拟磁盘是个块设备，并需要一个mkfs之类的命令才能真正地使用它，tmpfs是一个文件系统，而不是块设备；您只是安装它，它就可以使用了。
And while a traditional ramdisk is a block device and requires a MKFS command of some kind before you can actually use it, TMPFS is a filesystem, not a block device; you just mount it, and it's there.
负责向用户显示信息以及解释用户的命令。外部的用户有时可能是另外一个计算机系统而不是真正的人。
Responsible for showing information to the user and interpreting the user's commands. The external actor might sometimes be another computer system rather than a human user.
而图灵在1952年的论文是真正的杰作，它是从理论上对生物系统的理解一个全新的方法的发源地。
Instead, Turing's 1952 paper represents a true singularity, the origin of an entirely new approach to the theoretical understanding of biological systems.
一个真正的关系型数据库管理系统，既在逻辑层考虑到完全规范化的数据库，又提供数据的物理存储，这些数据为了高性能而被调整。
A true relational DBMS would allow for a fully normalized database at the logical level, while providing physical storage of data that is tuned for high performance.
因此，将环境资源作为一个整体对待的环境资源法，其真正目的应该是保持生态系统整体的价值，而不是保护这一整体中某一部分的价值。
So, the real aim of Environmental and resources Law that treats the environment and resources as an integer is to hold the value of the whole ecosystem but not the part of it.
埃勒森公共广播系统采用网络结构，而不是把各个系统要素连接到一个中央控制器上，而这样的结构使得系统设计获得了真正的自由。
The Elason PA system USES a network configuration rather than having all system elements connected to a central controller. This architecture gives real freedom in system design.
