Teary semiconducting AgSbTe2 nanowire arrays were synthesized for the first time by using the direct-current electrodeposition technique.X-ray diffraction,scanning electron microscopy,energy dispersive spectrometry,and transmission electron microscopy analyses indicate that the nanowire arrays are high filling,ordered,single crystalline and the nanowires have a highly preferential orientation grown along the [100] direction.Annealing studies show that compared with other temperatures,annealing at 100℃ can significantly increase the crystallinity of AgSbTe2 nanowires.The optical absorbance spectra of the AgSbTe2 nanowire arrays show that the optical band gap has a strong blue shift with decreasing the diameter of the nanowire.

摘要：一些老的电气控制系统没有配备触摸屏，设备故障报警功能不完善，没有报警历史记录可查。为此将触摸屏引入电气控制系统，并在PLC程序中增加故障捕捉功能，使设备具备“自诊断”功能，为设备的维护与检修提供及时有效信息。 关键词：触摸屏；故障报警；PLC程序；故障捕捉；自诊断 人机界面（HMI）是操作人员与PLC之间进行对话和相互作用的接口设备。用户可以通过人机界面与控制控制系统进行信息交换，向控制
