A real time clock module maintains operating and timing parameters in "non-volatile" or persistent memory when an integrated circuit is powered down.
实时时钟模块的维护工作和时间“非易失性”，或当一个永久的记忆集成电路关机参数。
Chris Brewin at University College London has confirmed that people suffering from depression or post-traumatic stress disorder (PTSD) are especially prone to this sort of persistent memory.
伦敦大学学院的克里斯·布鲁因证实了患有抑郁症或创伤后压迫紊乱症的人尤其倾向于具有这种永久记忆。
This naturally places restrictions on them as a computing platform; compute resources tend to be limited, in terms of processing power, memory, and persistent storage.
这就自然地限制了其作为计算平台的能力；计算资源容易收到处理能力、内存和持久性存储的限制。
Memory is the best persistent store for a cache because access time is (practically) instantaneous and RAM is typically plentiful (or cheap to amass).
内存是缓存的最佳持久性存储，因为访问时间(实际上)是即时的并且RAM的容量通常都很大(或者容易聚集在一起)。
Message cursors are part of a new memory model that allows messages to be paged in from storage when space is available (using Store cursors for persistent messages).
消息指针(MessageCursors)是新的内存模型的一部分，当有可用的空间时(对持久化的消息使用存储指针)，它可以在存储地对消息进行分页。
This problem can be solved by temporarily excluding the incomplete group from the message selector, or by copying the group to an in-memory or persistent store for completion later.
这个问题可以通过将不完整的组临时从消息选择器中排除得到解决，也可以将该组复制到内存中或持久性存储中，以便稍后完成。
While many good tools for dealing with persistent data are available, they all involve a lot more work than simply manipulating an in-memory data structure.
虽然有许多处理数据持久性的好工具，但是它们需要的工作都比简单操纵内存中数据结构要多得多。
In the prior steps, the module sections are loaded into kernel (temporary) memory, and you also know which are persistent and which can be removed.
在前面的步骤，模块区段被加载到内核(临时)内存，并且知道哪个区段应该保持，哪个可以删除。
Non-persistent messages are processed in memory and are very fast, but may be lost in the event of a system failure.
非持久化的消息是在内存中进行处理的，速度很快，但可能会因系统故障而丢失消息。
Part 1 of this article series included a code sample that showed how to replace a persistent XML document with another document held in memory.
本系列的第1部分包含一个代码样例，展示了如何用内存中的另一个文档替换永久xml文档。
Non-persistent messages live only in the memory of the message broker, and in the event of a crash they most likely are lost.
非持久性消息只存在于消息代理的内存中，出现崩溃时很可能丢失这些消息。
The following response header in Firefox prevents persistent caching, by forcing the page into the in-memory cache.
下面响应头在Firefox中可以防止持久化的缓存强制页面被缓存到内存中。
There's a EEPROM memory chip in the system for persistent storage of 10 perfusion curves as needed by the users.
系统内采用了EEPROM存储器，可对用户设定的多达10条灌流曲线进行长期保存。
