  1. To observe differential two kind of methods in pull out urinous catheter had to differential injure in bladder function, 80 patients divided into two groups at random : improved method of 40 patients and normal method of 40 patients and to ananlyse and compare successful rate in urinate, resumed rate in function of forced urinous muscle, stimulative symptom of urethra, incontinence of urine and retention of urine, that were from two groups patients

    摘要為觀察兩種不同的拔尿管方法對膀胱功能損傷的差異，將80例患者隨機分成兩組，分別採用改良法（ 40例）和常規法（ 40例）拔除留置尿管，分析比較了兩組患者排尿順利率、逼尿肌功能恢復率及尿道刺激癥、尿失禁、尿瀦留。
  2. 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。
  3. Let be a sequence of independent and identically distributed random variables ， with mean and variance. while the distribution function is unknown ， and is large ， then is a normal approximation distribution

    3設相互獨立的隨機變量服從同一分佈，已知均值為，方差為.單分佈函數未知，當充分大時，近似服從正態分佈
