By collecting ,testing, comparing, and analyzing the soil samples, soil recovery under the various recovery conditions along Mian CountyNingqiang highway was studied. The results were as follows herbaceous recovery to the soil fertility recovery in the prior was greater than the combination of grass and irrigation or than the pure bushes recovery. In each of them, the content of organic matter were 13.84, 7.50, 6.00 g·kg-1; In the recovery of herbaceous ecology, to grow leguminous plant and granminaceous plant together was better than pure graninaceous plant or pure leguminous plant. In each of them, the content of organic matter was 29.67, 17.51, 9.37 g·kg-1; to sow ryegrass and alfalfa together with some local grass seeds or to grow coxcomb, alfalfa and local couch grass together could bring better effects than to plant the alfalfa only. In each of them the increased organic matter contents were 4.93,17.51 and 9.37 g·kg-1;the quotas of the organic matter and alkaline hydrolysis nitrogen in soil fetility factor were closely connected, mainly because of the difference between the generation quantity and resolution quantity of the organic matter in the soil surface.

采集土壤样品，经室内分析化验，用对比分析的方法对勉县至宁强高速公路生态恢复中不同恢复类型条件下的土壤恢复进行了研究，结果表明草本恢复类型对前期土壤肥力的恢复作用大于草灌结合，并大于单纯灌木恢复类型，其中有机质含量分别为13.84、7.50和6.00 g·kg-1；在草本生态恢复类型中，豆科植物与禾本科植物混播恢复类型大于禾本科植物恢复类型的作用，并大于单纯豆科植物恢复类型的作用，其中有机质含量分别为29.67、17.51和9.37 g·kg-1；黑麦草与苜蓿混播并有当地草种入侵以及小冠花与苜蓿混播并播入当地草种羊茅，明显优于纯苜蓿单播，其中有机质含量分别增加了4.93和3.32 g·kg-1；土壤肥力因子中有机质与碱解氮两个指标有较好的相关性，主要与土壤表层有机质的生成量和分解量之差有关。

The mouse was carried out half nephric duct ligation to induce the renal interstitial fibrosis animal model,afterwards,to set up three groups,control group,sham operation group(intragastric administration with normal sodium according to 10ml/kg weight),treatment group...

采用小鼠单侧输尿管结扎法诱导肾间质纤维化的动物模型，用盐酸青藤碱治疗，并设对照组、假手术组(小鼠每日按10m l/kg体重用生理盐水灌胃，直至治疗结束)、治疗组(选用正清风痛宁缓释片按每日30mg/kg体重给小鼠灌胃，连续3周，)，检测血尿素氮、血肌酐、血清层粘连蛋白、纤维连接蛋白的含量，免疫组化法测肾脏组织转化因子β1(TNF-β1)的表达并进行肾脏病理学的观察。

But for different specialties people gave different models for secure network coding. For instance, J P Vilela introduced light weight secure network coding, and K Bhattad introduced weakly secure network coding. When considering the practical secure network, we must think over the network coding that resists active attack, that is to say resists Byzantine attack. In this paper we also introduce such kind of network coding.

蔡宁和杨伟豪首先针对单信源有向无圈网络给出了安全网络编码的定义和模型，其他研究者也各自提出了不同的安全模型，如J P Vilela提出了轻量级安全的网络编码，K Bhattad提出了弱安全的网络编码等，另外还有抗拜占庭攻击的网络编码。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
