The separation action of the gas anchor eliminates the effect of the gas on the subsurface pump and improves the efficiency of the pump; the gravity-type anti-gas device carries out gas-fluid separation by gas-fluid separating principle and chimney stack criterion: while the laser slotted screen pipe ensures the OD of sand in the fluid less than 0.05mm.

闭式气锚的分离作用消除了气体对抽油泵的影响，提高了泵效；重力防气装置利用液气分离原理和高烟囱原理进行液气分离，液流回流时间可达10 min，排气最高压差可达0.2 MPa；经激光割缝筛管过滤后的液体含砂粒外径小于0.05 mm。

The fuzzy clustering methods of the discretization is based on transitive closure.It has passed through a series of identical transformation. It may lose a lot of information in discretizated decision-making.

研究了基于模糊聚类的离散化方法，他们都是基于传递闭包的方法，经一系列的非恒等变换，使得离散后决策表信息丢失较多。

PDA was often combined with all kinds of intracardial malformation ,preoperational diagnosis and interoperative exploration are extremely helpful for diagnosis . A strict control of indication and the improvement of CPB technique are significant to lower the death rate and postoperative complication . Suturing PDA through incision in pulmonary artery under CPB is the main treatment for PDA, using Foley catheter to block arterial canal flow helps to fully expose the operating field 、shorten CPB duration and lower the complications of lungs and brain .

各种心内畸形经常合并PDA，术前诊断及术中探查，意义重大；严格掌握手术指征和提高CPB技术，对降低手术死亡率及术后并发症具有重要意义；经肺动脉切口缝闭PDA是CPB下处理PDA的主要方法，术中应用 Foley导尿管阻断动脉导管血流，有利于术野显露、缩短CPB时间，可降低肺部、脑部并发症。

Abstract］ objective to assess the efficacy and safety of transurethral resection of prostatewith plasmakinetic technique and to improve the qualities of pkrp.methods the data of 273 patients with benign prostatic hyperplasiawere retrospectively studied baseing on the mastering of pkrp.the average maximum urinary flow rate,the average residual urinary volumeand the average international prostate symptom score were analysed.results pkrp was successfully performed on 273 patients.intraoperative blood transfusion was performed in 6 cases,no obturator nerve reflex,transurethral resection syndrome,permanent urinary incontinence occurred and no death cases occurred.the follow-up time was 2～26 months with an average of 5.63 months,postoperative average qmax increased to 15.9 ml/s,and ruv decreased to 16.0 ml/s and the average ipss was 9.compared with those of preoperation,the differences were significant.conclusion pkrp has superior tissue cutting function and hemostasis.it is suggested that transurethral bipolar plasmakinetic resection of prostate be effective and safe.

目的 探讨经尿道双极等离子前列腺切除术的安全性与有效性，提高pkrp质量。方法回顾性分析273例良性前列腺增生患者pkrp资料，比较手术前后最大尿流率、膀胱剩余尿量及国际前列腺症状评分。结果 273例手术均顺利完成，术中输血6例，无闭孔神经反射、永久性尿失禁、经尿道电切综合征及死亡病例，随访2～26个月，平均5.63个月，qmax平均增至15.9 ml/s，ruv平均降至16.0 ml，ipss平均9分。与术前相比，各项指标均有明显改善。结论 pkrp具有良好的组织切割功能及可靠的止血作用，治疗bph安全有效。
