objective:to explore the value of laparoscopy in diagnosis and treatment of female infertility.methods:the clinical data of 139 cases of female patients with infertility were analyzed retrospectively.results:among 139 cases,55 cases with pelvic adhesion,34 cases with salpingitis,20 cases with endometriosis,and 14 cases with polycystic ovary.the pregnancy rates were 47.27%,41.18%,55.56% and 46.15% respectively after laparoscopic surgery.pelvic adhesion salpingitis and endometriosis were the major cause of female infertility.conclusions:laparoscopic technique can find out the reason of infertility more earlier and more directly and provide timely therapy.so it has excellent clinical effect.

目的：探讨腹腔镜诊治女性不孕症的应用价值。方法：回顾分析我院2004年12月至2007年12月应用腹腔镜诊治女性不孕症139例患者的临床资料。结果：139例中盆腔粘连55例，输卵管炎34例，子宫内膜异位症20例，多囊卵巢综合征14例，术后妊娠率分别为47.27%，41.18%，55.56%，46.15%。盆腔粘连、输卵管炎、子宫内膜异位症是引起女性不孕的主要盆腔病因。结论：应用腹腔镜技术能早期、直观、准确的明确不孕症输卵管及盆、腹腔病因并可同时予以针对性治疗，在直视下通液，动态观察输卵管通畅度和形态，大大降低了常规通液术的假阳性、假阴性率。

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。

The vibro-impact systems are familiar with the non-smooth dynamic systems.The dynamics research of the vibro-impact systems not only is significant in theory but also has practical values in engineering.Firstly,using the Poincaré map method,we get an existent criterion of single impact period-n motion in a two-degree-of-freedom vibro-impact system with damper.It is shown that our conclusions are valid through the numerical simulations.Moreover,the satiability of periodic motions is studied and the correspon...
