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
摘要為探討竹簽接觸血清樣品時間對鉀離子濃度影響的程度，採用離子選擇電極法分別對竹簽在血清中浸泡不同時間的樣品鉀離子濃度進行測定，並以配對t檢驗對不同浸泡時間的血清鉀離子濃度進行對比。 -
To solve this difficult problem, this paper presents an innovated digital matching machining method, which integrates many techniques such as curved surface automatic tracking, data acquisition, mathematical analysis, cnc and digitizing. a new algorithm is introduced to track and sample a large - scale rotary surface with the use of three - dimensional scanning probes
研究了蒙皮內表面的數字化採集技術，提出了採用三維掃描測頭進行大型不規則回轉面自動跟蹤測量的控制演算法及密集數據採集方法；研究了蜂窩夾芯表面的數字化加工技術，提出了以回轉軸為基準的隨動控制插補方法。 -
Then the unified approach can be applied to it to acquire the ensemble random evolutionary response. since the normal probability density function ( pdf ) may lead to instability of some sample systems when the random parameters taking sufficiently small negative values, an arch - like pdf and a more adaptable - pdf, together with the matching chebyshev polynomial approximation and gegenbauer polynomial approximation, are suggested. numerical examples show that the suggested methods are effective
相比較而言，隨機模擬法的結果無疑是最可靠的，但是它的計算量嫌大；隨機攝動法的計算量遠小於隨機模擬法，但是它要求隨機攝動量必須是一個小量；正交展開法的計算精度好於隨機攝動法，其得到結果與隨機模擬法得到的結果幾乎吻合，其計算量略多於隨機攝動法，但與隨機模擬法相比要少的多，不過計算前的準備工作較費時。
