Investigation and evaluation of soil and water resources in Minqin Oasis indicate that the proportion of grain crop, cash crop and grass is 36.94:45.16:17.90 for 2005. And a comparison with that for 1991 indicates that land use structure is developing towards rational proportion of grain crop, cash crop and grass; and harmony among agriculture, stockbreeding and forest. The main limiting factors of land resources are water, soil quality, salinity and fertility, and there is about 3.9218×10^8 m^3 water deficit per year in Minqin Oasis.

通过水土资源现状的分析评价，发现2005年民勤绿洲粮经草比例为36.94：45.16：17.90，与1991年相比，土地利用格局正向粮经草比例优化和农林牧协调方向发展；民勤绿洲土地资源的限制性因素主要为水分、土质、盐碱和肥力；对水资源现状分析发现民勤绿洲年缺水量达3.9218亿立方公尺。

Based on the theory on the design of the solid liquid two-phase flow centrifugal pumps and considering the characteristics of the soil under water and the operation characteristics of the dredge pump, the design method of the dredge pump impeller is presented, the corresponding Visual Basic program is developed and the solid model of impeller is also created by using Pro/E. The parameterized design of the slurry pump is realized.

本文在现有的固液两相流泵设计理论的基础上，针对疏浚工程土质特性和疏浚泥泵工作特点，提出了疏浚泥泵叶轮的设计方法，开发了相应的Visual Basic程序，并应用Pro/E进行了叶轮实体造型，实现了疏浚泥泵叶轮的参数化设计。

However, there was great concerns about the detrimental differential settlement that could be induced by factors such as non-uniformly distributed structural loadings, backfills around the stadium, and a 2m excavation within the stadium. It was later concluded by the design team that a pile-raft foundation system is required.

世运馆原设计为采用筏式基础，但因考量结构荷重不均均分布、场外回填土、场内降挖2m及地表下存在厚约26m之粉土质黏土可能产生过大之差异沉陷进而造成结构体损坏，故变更基础设计为桩筏共构。

Theoretical analysis shows that ground movement patterns induced by shield tunneling construction for different kinds of soils will be different.

理论分析表明，不同土质条件下盾构法隧道施工引起的土体移动模型有区别。

Habitat loss takes several form-:S: outright loss of areas used by wild species; degradation, for example, from vegetation removal and erosion, which deprive native species of food, shelter, and breeding areas; and fragmentation, when native species are squeezed onto small patches of undisturbed land surrounded by areas cleared for agriculture and other purposes.

栖地的消失有几种型式：如，野生物种栖地的澈底消失；植被移除或腐蚀导致土质恶化，影响原生物种的食物、栖地、养育地；或因为农业或其他用地的使用，使原生物种被迫迁移至未受干扰但被其他用途所围绕的小块土地时，其活动区域遭到分割。下一个： hail。。。是什麼意思啊？

On one side of the road rose a high rough bank where hazels and stunted oaks with their roots half exposed held uncertain tenure: the soil was too loose for the latter; and strong winds had blown some nearly horizontal.
