Results show that potassium ion concentration has a gradual higher with the extension of bamboo stick immersion times in a certain time and that statistical differences among serum potassium ion concentration at difference times is significant ( p < 0 . 01 ) 结果表明：在一定时间范围内，钾离子浓度随竹签浸泡时间的延长而呈逐渐增高趋势，其差异具有统计学意义( p < 0 . 01 ) 。
During soleus exposing to high - frequency stimulation , potassium ions accumulation and sodium ions exhausting are formed rapidly in t - tubule . the ion concentration alterations in t - tubule lead to a depolarization block of t - tubular action potential , then inhibit the function of l - type ca2 + channels 萎缩使sol肌纤维t管内k ~ +更易集聚， na ~ +更易耗竭，动作电位由t管向内传导易受到阻滞，从而使l型钙离子通道功能受抑制。
However , the nbcl5 - precursor sbn thin films exhibits the same high preferred orientation on si substrate and the smallest full width at half - maximum ( fwhm ) value is only 2 . 5 ? which is the best result for sbn thin film deposited on si substrate by the sol - gel method . it was investigated by x - ray diffraction and second ion mass spectrum that the nbcl5 - precursor sbn thin films contained potassium ion 同时，先在si衬底上生长掺k的sbn (灯nb = 2 / 3 )薄膜作为sbn薄膜的缓冲层，再在该衬底上生长不含k的sbn6o薄膜，薄膜表现出非常完美的择优取向，杂峰几乎被完全抑制。
To explore the effect of bamboo stick contacting time with serum sample on serum potassium ion concentration , we have systematically measured serum potassium ion concentration of bamboo stick contacting with serum sample at different times using ion selective electrode method and analyzed their potassium ion concentrations using matching t test 摘要为探讨竹签接触血清样品时间对钾离子浓度影响的程度，采用离子选择电极法分别对竹签在血清中浸泡不同时间的样品钾离子浓度进行测定，并以配对t检验对不同浸泡时间的血清钾离子浓度进行对比。
