位校验

The most obvious disadvantage of asynchronous data transmission is the need for a start, parity, and stop bit for each transmitted character.

对于一个传送的字符，异步数据传输都需要起始位、奇偶校验和停止位，这是它最明显的缺点。

A binary check digit;for example, a parity bit.

一个二进制校验位，例如奇偶位。

Data bit, 1 stop bit, no check bit.

8，n，1 8 个数据位，1 个停止位，没有校验位。

Fortunately,however,computer designers have developed a method for detecting such errors by add an extra check bit or parity bit to each 6,7,or 8-bit character represented in storage.Thus,as you can see,a total of 7,8,or 9-bits may actually be stored.

但幸福的是计算机设计者已研制了一种检测这种错误的方法，这就是，对在存储器中表示的每个6位、7位或8位字符增加一个附加的检查位或奇偶校验位，这样，正如你所看到的，实际存储的是7位、8位或9位。

A subcarrier arranging part (103) rearranges the data to be transmitted so that the systematic bit data will be arranged on a subcarrier in the vicinity of the center frequency and the parity bit data will be arranged on subcarriers in the vicinity of both ends.

副载波安排部件(103)对要发送的数据进行重排，使得系统位数据将被安排在中心频率附近的副载波上，而奇偶校验位数据将被安排在两端附近的副载波上。

If either Even or Odd Parity is specified, the quantity of 1 bits will be counted in the data portion of each character (seven databits for ASCII mode, or eight for RTU).

如果指定了奇或偶校验，"1"的位数将算到每个字符的位数中（ASCII模式7个数据位，RTU中8个数据位）。

If Odd Parity is used, the parity bit will be a 1, making an odd quantity.

如果便用了偶校验，帧的奇偶校验位将是0，便得整个"1"的个数仍是4个。

Of odd parity, the parity bit is set to "1" or "0" so that the total number of"1" bits in the block is odd.

假如是奇校验，奇偶校验位将被设置为1或0，使这个块的奇偶为奇。

Can automatically send the parity bit to support a variety of validation format.

可以自动发送校验位，支持多种校验格式。

When the received character has been assembled, its parity is calculated and compared with the received parity bit following the character.

当接收到的字符汇齐后，它的奇偶校验位就由计算得出并与接收到的奇偶校验位进行比较。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
