In view of the demand of signal environment reconnaissance and surveillance,the model for azimuth-frequency two dimensional energy distribution is established,on the basis of the current radar counter-measure reconnaissance technical system,in this paper.In this model,the scope of reconnaissance is divided into several cells in accordance with azimuth and frequency,and the signal spectrum energy in each cell represents the size of the cell.And then a model for random changing energy is analyzed,via which,a method for signal monitoring of abnormal electromagnetic targets is presented.Theoretical analysis and simulation results prove that this model and monitoring scheme are of availability,providing a reference for the function extension of the equipment in service.

To actual situation of using one point gas testing method in Wen23 gas field at the middle and later exploiting period, data from 44 wells of deliverability test with multiple points are studied statistically. By correlative analysis of binominal basic relationship and dimensionless pressure and producing rate, an empirical equation to calculate open flow potential suiting for Wen23 gas field is induced. Practiced application shows it is reasonable and has an important guiding sense.

[Objective] To explore the surgical principle and method for elderly left half colon cancer obstruction.[Methods] Surgical treatment results of 38 cases with colon cancer were retrospectively analyzed.[Results] All patients were conducted one-stage resection and anastomosis with intraoperative intestinal decompression and sausage.[Conclusion] Elderly patients with more complications and serious disease must be given surgery as soon as possible.If patients' conditions are permitted,one-stage resection and anastomosis is the best surgical program..

<正>我院2000年1月—2005年11月收治外伤胰腺损伤后胰瘘8例,效果良好,现分析报告如下。1资料与方法1.1一般资料本组8例,男5例,女3例。年龄14～60岁。车祸伤5例,刀刺伤1例,高空坠落伤1例,马踢伤1例(此例14岁男孩为2005年"全国万名医师支援农村牧区工程"中所做手术病例)。7例闭合性损伤,1例为腹部开放伤。本组7例在伤后6～12h内就诊,1例马踢伤者伤后1个月就诊。全组8例均伴有左上腹痛及左后背痛,均伴有腹膜炎,其中6例并发休克,6例腹穿抽出不凝血,检测淀粉酶均高于正常值。B超检查8例

目的探讨治疗前列腺增生症(BPH)的有效手术方法。方法采用经尿道前列腺电切术治疗BPH36例。结果患者平均住院6d,留置导尿管平均5.5d,拔管后均排尿通畅。术后随访6~18个月,患者经国际前列腺症状评分(IPSS),平均为9.0分,未出现严重并发症。结论经尿道前列腺电切术是一种并发症少、安全性高、疗效确切的手术方法。
