These kinds of people are ideal prey for those seeking "bait" animals for fighting dogs, cats and dogs to sell to laboratories, or guard dogs to chain up and neglect.

这种人是那些专门替斗狗找动物饵、卖猫狗去实验室或是被拴住和忽视的看门狗。

The system adopts CPU board with fast processing elevator operational program, data signal exchange, and HMI screen, which can make sure reliable operation and high speed. It also has PHILIPS SJA1000T field CAN bus, 82C251 Bus interface and the latest serial storage technique to record data. The functions of external watchdog and control chip internal watchdog compose two-level procedure monitoring, so as to ensure the normal operation of the control program. Heavy-current switch power LM2576 ensures the stable system working power, which has low requirements for the power supply. High-speed optoelectronic isolator and internal frequency division technology can make NW3P08-41C (42C) CPU receive the input impulse up to 1-phase 100 KHZ*2 CHANEL or 2-phase 50KHZ*1 CHANEL 32bit.

系统采用原装中央处理板，具有快速的处理电梯运行程序、数据信号交换、显示屏人机界面；确保可靠运行电梯控制程序；且速度快，PHILIPS 公司 SJA1000T 现场 CAN 总线；以及 82C251BUS 接口，最新串行存贮技术记录数据；外部看门狗及控制芯片内部看门狗功能组成两级程序监视，确保控制程序正常运行；大电流开关电源 LM2576 确保系统工作电源稳定，且对供电电源要求低；高速光电隔离光藕及微机内部分频技术，使 NW3P08-41C(42C)中央处理板可接收高达 1 相 100KHZ*2通道或 2 相 50KHZ*1通道，32bit 的计数脉冲。

The method comprises the following steps of: starting the watchdog; counting from 0, the watchdog detects that the system reads the counting value; calculating the remainder after the counting value is divided by a pre-arranged value; re-counting from the remainder by the watchdog.

方法包括：看门狗启动，从0开始计数，看门狗检测到系统读取计数值，计算计数值除以预设值后所得的余数，看门狗从该余数起重新开始计数。

Absent. The watchdog counter stops decrementing with the failure of the input clock and does not change with the limp-mode clock.

路。看门狗计数器随着输入时钟的减弱而停止计数，在保护模式下，看门狗计数器不发生变化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
