Set at least 2 seconds , the nixietube shows the upper limit temperature , and upper limit led lights , then using 秒,进入设置状态,这时“温度上限”灯亮,数码显示器上显示上限温度,用“
Set and hold it for at least 2 seconds , the controller displays the upper limit temperature , and upper limit led lights , then using the key 秒,进入设置状态,这时“温度上限”灯亮,数码显示器上显示上限温度,用“
The linear compensation bandgap reference adopted in this thesis has limited temperature stability for ignoring the influence of vbe high order items 仿真结果表明采用高阶补偿后,带隙基准源的温度系数由22 . 8ppm /减小为7 . 8ppm / 。
How to set the upper limit temperature and the lower limit temperature ? press the select key to make the light of temperature upper limit light , the nixietube shows the upper limit temperature , press the key 按“选择”键使“温度上限”灯亮,数码显示器上显示上限温度,用上或下键改变设定值“
Press and hold them over 0 . 5 seconds can add or minus rapidly , and you can set the lower limit temperature in the same way when you press the select key again , and finally press the select key to exit the setting state 0 . 5 c ,按住不放超过0 . 5秒则快速增减,再按一次“选择”键可按同样方法
The temperature field of the huge stream turbine rotor during free forging is numerically simulated with different process parameters . the purpose is to find out a set of optimum process parameters so that the temperature of the rotor center does not exceed the limit temperature of abnormal grain growth which is about 1100c 对大型汽轮机转子锻造过程中的成形火次进行了温度场的数值模拟和优化,得到了控制转子锻件心部温度不超过1100的工艺参数,为实际生产解决混晶问题提供了参考数据。
