1·Conclusions the application of DSAK in lateral window maxillary sinus lifting could shorten the surgery time obviously with low membrane perforation rate and slighter postoperative reaction.

结论应用新型上颌窦提升工具进行上颌窦外提升术较普通球钻手术时间明显缩短，黏膜穿孔率低，患者术后反应轻，高效安全。

2·Perforation and death rate were respectively 5.6% and 4%.

穿孔率和死亡率分别为5.6%和4%。

3·Between 1 October and 10 December 2004, 615 severe cases with peritonitis, with or without perforation, including 134 deaths (case fatality rate, 21.8%) have occurred.

从2004年10月1日至12月10日，已发生615例伴有穿孔性或非穿孔性腹膜炎的严重病例，其中包括134例死亡(病死率为21.8%)。

4·Results Of 83 cases, 78 were treated successfully, ureteric perforation occurred in 1case, stones went into kidney in 2 cases, the cure rate was 92.7%.

结果输尿管中下段结石83例，78例碎石成功，术中1例出现输尿管穿孔，2例结石上移至肾盂内，成功率92.7%。

5·The stone free rate of URL was 100% for lower ureteral stones, There was no ureteral perforation and avulsion happened.

URL对输尿管中下段结石取净率为100%，术中无输尿管穿孔、撕脱等并发症发生。

6·The doctors found that having higher tympanogram volumes could result in a nearly 90 percent success rate for patching the perforation.

医师们发现鼓室导抗图容积较高的患儿的耳膜穿孔修补成功率近90%。

7·The flow rate, perforation radius and shot density are the key parameters influencing the pressure drop across gravel pack.

分析结果还表明，油井产量以及射孔孔径和孔密度是影响砾石层压降的重要因素。

8·The minimum injection rate of gravel pack increases while increasing the diameter of perforation tune, the perforation density, the perforated thickness and the critical velocity.

射孔密度、射开厚度、孔眼直径及临界流速增加时，砾石充填最小排量也增加。

9·Peptic ulcer perforation is the one of surgical abdomens, with high incidence and mortality rate.

消化性溃疡穿孔是目前临床上常见的急腹症之一，其发病率及病死率高。

10·On the basis of this theoretic model, the critical production rate, the shape of water coning and the optimum perforation intervals could .

在理论模型的基础上，建立了预测临界产量、水锥形态以及优化射孔长度的数学模型。
