预先分配

In particular, readers accustomed to using C or Java might expect that because vector elements are stored contiguously, it would be best to preallocate the vector at its expected size.

具体而言，如果读者习惯了 C 或 Java 的风格，由于 vector 元素连续存储，可能希望最好是预先分配合适的空间。

If the sending end station determines that the destination address is not local, the packet goes to a first－hop router, typically one that is close and has been preassigned to the sender.

假如发送端站确定目的地址不在本地，该包就被送到第一跳路由器，一般来说，该路由器是在四周的，并已被预先分配给发送者。

If the sending end station determines that the destination address is not local ,the packet goes to a firsthop router ,typically one that is close and has been preassigned to the sender

如果发送端站确定目的地址不在本地，该包就被送到第一跳路由器，一般来说，该路由器是在附近的，并已被预先分配给发送者。

Memory management technique that involves preallocating unconstructed memory to hold objects that will be created as needed.

一种内存管理技术，涉及预先分配未构造内存以保存在需要时创建的对象。

One common strategy is to preallocate a block of raw memory to hold unconstructed objects. When new elements are created, they could be constructed in one of these preallocated objects. When elements are freed, we'd put them back in the block of preallocated objects rather than actually returning memory to the system.

一个通用策略是预先分配一场原始内存来保存未构造的对象，创建新元素的时候，可以在一个预先分配的对象中构造；释放元素的时候，将它们放回预先分配对象的块中，而不是将内存实际返还给系统。

Also, it's a good idea to portion out a serving size beforehand, so you don't absentmindedly munch a thousand or so calories from a big bag.

所以，最好预先分配好量度，要不在你精神不集中的时候从一个大袋子里摄入过多的卡路里。

Although we can preallocate a given number of elements in a vector, it is usually more efficient to define an empty vector and add elements to it (as we'll learn how to do shortly).

虽然可以对给定元素个数的 vector 对象预先分配内存，但更有效的方法是先初始化一个空 vector 对象，然后再动态地增加元素（我们随后将学习如何进行这样的操作）。

A common strategy such classes use is to preallocate memory to be used when new objects are created, constructing each new object in preallocated memory as needed.

这样的类使用的通用策略是，预先分配用于创建新对象的内存，需要时在预先分配的内存中构造每个新对象。

An image display apparatus includes a display having data holding function, a vertical drive circuit sequentially and selectively scanning matrix form display elements, and a horizontal drive circuit writing a voltage among binary voltage preliminarily assigned depending upon the digital data of the image signal. The horizontal drive circuit and the vertical drive circuit are operated for performing selective scan of respective display element for at least m times in one frame period. The vertical drive circuit is constituted of n number of sequence circuits and logic operation circuits for outputs of the sequence circuits, where n is smaller than m, a period from inputting to the sequence circuit to outputting from the final stage being less than or equal to half of one frame period, and at least one of the sequence circuits being used with selectively inputting a plurality of inputs.

提供了一种图象显示器，其具有显示部，在矩阵上排列的象素内保有数据保持的功能，根据保持的数据进行显示；垂直驱动电路，对构成显示部的矩阵状显示器以每行按顺序作选择性扫描；以及水平驱动电路，对于由垂直驱动电路选择的行显示器件，根据应显示的图象信号数字数据，从预先分配的二进制电压中写入电压，并利用水平、垂直驱动电路，与应显示的图象信号同步，在1帧期间至少m次对各显示象素进行选择性操作，以此进行多色调显示，垂直驱动电路由满足n＜m的n个顺序电路和其输出的逻辑运算电路组成，顺序电路的输入从最后级输出为止的期间为1帧期间的1/2以下，并且，n个顺序电路的至少一个的输入是切换多个输入系统而使用。

This is not an ordinary box, which is used as a background picture of the dialog box, very pretty.

详细说明：这可不是一个一般的对话框，它是用图片作为背景的对话框，非常好看。

Conceal me what I am,and be my aid for such disguise as haply shall become the form of my intent.

遮掩我的身份，帮助我，我的面具将成为我的目的。
