介绍了当前普通标记机控制系统现状及其存在缺点，给出气动标记机及相频修正PWM模式的工作原理。采用ATmega16单片机和USB转换RS232接口器件CH341T实现驱动控制系统与PC的实时通讯，标记控制系统可升级到USB接口。采用基于ATmega16的相频修正PWM替换555振荡电路产生的PWM，可直接通过软件调整PWM信号。使用达林顿三极管TIP122替代直流继电器驱动高频电磁阀，使得电磁阀驱动电路简单，成本低廉。该控制系统已成功应用于气动标记机。 Abstract: In this paper,the actuality and demerit of the common gas marking machine control systems are described.The operation principle of the gas marking machine and the phase and frequency correct PWM of ATmega16is introduced.The real-time communication between the driving control system and PC by CH341T which its function is translated USB to RS232is realized,the control systems is updated grade to USB interface.The PWM signal can be adjustable by software for the555surge circuit was substituted by the phase and frequency.The high frequency electromagnetic value’s driving circuit by DC relay is replaced by TIP122,therefore,the circuit is become simple and the cost cheap.The control systems has been widely used in gas marking machine.

Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increasingly important. The compressed signalprocessing range mandates a commensurate reductionin reference noise to maintain resolution. Noise ultimatelytranslates into quantization uncertainty in A to D converters,introducing jitter in applications such as scales, inertialnavigation systems, infrared thermography, DVMs andmedical imaging apparatus. A new low voltage reference,the LTC6655, has only 0.3ppm (775nV) noise at 2.5VOUT.Figure 1 lists salient specifi cations in tabular form. Accuracyand temperature coeffi cient are characteristic ofhigh grade, low voltage references. 0.1Hz to 10Hz noise,particularly noteworthy, is unequalled by any low voltageelectronic reference.

简易学生成绩排序（汇编） 编制一程序，要求接收从键盘输入的一个班的学生成绩，并存放于50字grade数组中，其中grade+i保存学号为i+1的学生成绩。然后根据grade中的学生成绩，把学生名次填入50字rank字数组中，其中 rank+i的内容是学号为i＋1学生的名次。再按学号顺序把名次从终端上显示出来
