该文报道了钨超微电极的制作方法，利用电化学氧化的手段在钨超微区域衍生三氧钨膜而制成三氧化钨／钨（WO3／W）pH超微电极。实验发现，在pH2．0～13．0的范围内，WO3／W超微电极对H＋是较好的响应，相关系数为0．9996，斜率为56．6mV／pH。将超微电极应用于心肌细胞缺血性损伤的研究中，结果满意。
This paper reports the fabrication of tungsten ultramicroelectrode by electrochemically oxidizing Tungsten trioxide / tungsten (WO3 / W) pH ultrafine electrode in the ultrafine tungsten region. It was found that the WO3 / W ultramicroelectrode had a good response to H + in the range of pH2.0 ~ 13.0 with a correlation coefficient of 0.9996 and a slope of 56.6mV / pH. The ultramicroelectrode was applied to the study of ischemic injury of cardiomyocytes with satisfactory results.
