In addition to four nmerac place position,there are three zone bit positions in a 7-bit code,and four zone bit in an 8-bit code.The 7-bit American Standard Code for Information Interchange is widelu used in data communication work and is bu far the most popular code used to represent data internally in personal computers.

除了4位数字位之外，在7位编码中有3个标志位，而在8位编码中则有4个标志位。7位美国信息交换标准代码广泛地用于数据通信，而且是目前个人计算机内部数据表示中最为流行的代码。

In addition to the four numeric place positions, there are three zone bit positions in a 7-bit code, and four zone bit positions in an 8-bit code: The 7-bit American Standard Code for Information Interchange is widely used in data communications work and is by far the most popular code used to represent data internally in personal computers.

因为64种可能的位排列仍不能满足十进制数（10个）、小写字母（26个）、大写字母（26个）和大量的其它字符（26个以上）编码的需要，所以设计者将6位BCD码扩充到7位和8位。7位二进制数可以提供128种不I司的排列(2 ')；8位二进制数可以有256种排列（2）。

To the same kind of rocks, the penetration rate increases with the increases of electric bit thermal power. When electric bit thermal power keeps fixedness, the penetration rate increases in various degrees with the increases of bit load in difference rocks. Increasing the bit load is beneficial to improve the quality of glass hole wall, but the bit load should not be too big.

对于同一种岩石，钻进速度随钻头电热功率的增大而增大；当钻头电热功率不变时，根据所钻岩石岩性的不同，钻进速度随钻头轴载的增大而不同程度地增大，增加钻头轴载有利于提高玻璃状孔壁的质量，但不宜过大。
