Basisd on the controlled stocking rates, comparable repeated experiment was conducted to understand the stability of grazing ecosystem in vegetation, soil and livestock, considered the year as the principal component to evaluate the effect and mechanism of annual precipitation on grazing ecosystem characteristics, using the coefficient of variation in terms of ANPP and decrease and increase of functional groups to reveal the ecosystem stability and ecological compensatory effect in grazing ecosystem. The result not only richens the study contents of ecosystem stability, but also provides a guide for adaptive rangeland management plans, which are promoted the ecological and economic sustainable development.

本研究首次采用重复性对比研究，对草原放牧生态系统的稳定性在草-土-畜3个方面的体现进行综合对比，分析年度和载畜率的协同效应，揭示降水量对草地生态系统稳定性维持的影响机制，运用草地植被地上净生产力的变异性和功能群的消长阐明载畜率对放牧系统稳定性和系统内部生态补偿效应的影响，不仅丰富了草原放牧系统的研究，而且对内蒙古荒漠草原草地适应性管理措施的制定和实施具有指导意义。

Pls don't compare construction quality of San Fran. skycrapers to Navajo shams - you are doing so by comparing Beijing to Beichuan.

因此请你不要在建筑物的施工质量方面，把纳瓦霍来对比旧金山的高楼大厦，不要拿北川来对比北京。

In order to solve the frost heave and thaw settlement, the model tests were made in Tibetan Plateau. Two kinds of model were designed to horizontal drain structure embankment and the ventilation embankment in suit. The effect of horizontal plastic drain was analyzed in contrast with the ventilation embankment. The mechanisms of horizontal plastic drain were studied in permafrost, such as gravity draining in the superficial layer and structure stiffing in the embankment in the theory. According to the design theory, the parameters of horizontal plastic drain were confirmed in the embankment. The values of deformation were inspected by fiber monitor system in the permafrost embankment.

为了解决青藏高原的冻土浅层雨季雨水下渗和蒸发所产生的冻土冻胀与融沉问题，在青藏高原开展水平排水板结构性路基和普通通风路基的原位模型对比试验，并从理论上探讨水平排水板在多年冻土路基中浅层重力排水和结构加劲的作用机理，确定水平排水板的铺设参数；运用光纤监测技术对水平排水板在多年冻土路基中的变形进行监测，对比分析水平排水板铺设与否这2种条件下冻土路基变形监测结果。

摘 要：为了解决青藏高原的冻土浅层雨季雨水下渗和蒸发所产生的冻土冻胀与融沉问题，在青藏高原开展水平排水板结构性路基和普通通风路基的原位模型对比试验，并从理论上探讨水平排水板在多年冻土路基中浅层重力排水和结构加劲的作用机理，确定水平排水板的铺设参数；运用光纤监测技术对水平排水板在多年冻土路基中的变形进行监测，对比分析水平排水板铺设与否这2种条件下冻土路基变形监测结果。

By superposing the vector of residential area with boundary of counties, the residential area A(subscript m of every district is calculated.

在模拟结果的基础上估算乡镇级人口，对比分析乡镇级估算人口和实际调查人口对结果进行验证，对比数据表明该算法所得到的人口分布与实际人口分布较为相符。

According to the different testing ways to the different testing rates of the defaults, in order to reduce the possibility of failing to test,this paper makes contract with different testing methods,and then gets trustier testing method by constracting and analysing.

为了尽可能减少漏检的可能性，本文对不同的检测方法进行了对比，经过对比试验分析得出更可靠的检测方法。

Research conclusions:In the repetition survey for precise control of outside tunnel, it can be verified whether the result of repetition survey meets the requirement of construction accuracy or not through making comparison of the distance with azimuth of corresponding baseline.

研究结论：在隧道洞外精密控制测量的复测中，对组成的同名基线进行距离和方位角对比，可以很快验证复测成果是否符合施工精度要求；同名基线的验证方法可以有效地反映观测误差对隧道横向贯通误差的影响；工程实践证实，同名基线对比分析可避免过于繁琐的内业工作，及时确保施工安全和进度。

First the concept and design parameter of these two methods were compared in this paper. Then the analytical results of a tall hybrid structure were analyzed under structure class B and C of minor earthquake, and under elastic and non-yielding design of moderate earthquake. The results and conclusions drawn in this paper can be referred by the structural design and code revision.

文中首先就这两种设计方法的概念、具体设计参数进行了对比分析；然后以某一高层混合结构为例，对比了按7度丙类建筑小震、乙类建筑小震、丙类建筑中震不屈服、丙类建筑中震弹性下的设计结果，得到的一系列结论可供设计人员和规范修编参考。

The fertilizer test base on three aspect of grain size、growth velocities 、rate of the green parts, the result present that IBDU multiple fertilizer is bigger grain size and quirkier hydrolyze rapid and more short release period than UF multiple fertilizer, which work easier burning spot on grass leaf of Green lawn; on aspect of growth

肥料对比试验中，进行了颗粒大小、生长速度和绿叶率变化等三个指标的测试，结果指出IBDU技术肥料相对UF技术肥料在沙土环境中具有水解速度快，养分释放周期短等特点，并且大颗粒的IBDU技术肥料容易在水解过程中对果岭草坪产生灼烧性斑点，而对比试验使用的UF技术肥料由于粒径较小相对克服了此点不足；在生长速度和绿叶率变化方面，IBDU果岭均提前于UF果岭达到生长高峰和全绿率，也提前下降生长速率和绿叶比值，试验最终IBDU果岭的日生长量和绿叶率均明显低于UF果岭的数值。
