查询词典 poor area

Huangshi professional school established in 1984 ,it transported a great deal of worker for the southeast region of Huangshi and HuBei area from beginning till middle 90's in 20 centuries, with the positive interaction of the industrial structure of Huangshi,it once has great glorious at that time, after 90' to 2005, being subjected to the domestic influence of the poor environment, the quantity of students decreased year by year, some profession atrophy completely disappeared and recruited severals or more than ten studentses only, though school often recruits lately,it still can't impede it heads for the falling off footstep.

The simulation results of the cylinder-block model were given in the article, consistent with that of Middlemen"s. It was shown that the block part could improve the uniformity of the flow distribution. The analysis of the flow field of some materials with different power-law factor in the die designed by Mckelvey was close to that of Mckelvey"s. It was shown that the flow distribution was uniform in the die that can producesheets with 1200mm in width. During the analysis the flow channel was divided into several parts to get the details about the fluid flow in each area. A conclusion was drawn after analyzing the influence of the die pressure on the flow distribution, that the higher pressure is good for the output and bad for the uniformity of the distribution. Simulation of the die applying the cylindrical main runner showed the fact that when the cylinder replaced the cone the change of uniformity was trivial. The uniformity of the non-block flow channel was so poor that the block in the proper position of the die channel was necessary. The project of the die for the wider sheet was put forth, and the analysis of the fluid flow in the die was shown.

本文模拟了圆柱管缝隙流模型的三维流动场，得到了与Middlemen结论一致的流动均匀性，并通过模拟直观地展示了采用阻尼块可以改善挤出均匀性的现象；分析了多种幂率指数的流体在Mckelvey等人设计的流道模型中的流动分布，得到了与Mckelvey的分析结果接近的压力降和流量偏差；本文建立了1200mm幅宽机头流道的三维有限元模型，并逐个分析各个区域和多个截面的流动分布状况，由此揭示了1200mm幅宽L-型机头流道内的流北京化工大学硕士学位论文动分布基本均匀，并在分析了机头压力对于挤出流动分布的影响后得出结论：较高的机头压力可以获得较大的产量，但是不利于物料均匀分布；模拟了采用圆柱管主流道时机头流道内的流动分布，得出结论：主流道由圆锥管改为圆柱管时对流动均匀性影响不大，通过设置适当的阻尼仍然可以达到挤出平衡；模拟了两端进料式圆柱管无阻尼流道的流动均匀性后得到结论：两端进料式无阻尼结构的流动均匀性较差，宽机头中仍然有必要设置阻尼块；确定宽幅机头流道的基本方案，并设计了一种宽幅防水卷材挤出机头流道的结构，通过流动模拟表明该种结构的流动均匀性较好；考察了宽幅机头对于不同厚度片材的挤出适应性，得到结论：当生产不同厚度的片材时，阻尼块高度需要调整。

Secondly was honeysuckle and peach tree wood.So,in poor karst area,in order to link environmental benefits,eco-efficiency and social and economic efficiency,it were best measures to plant prickly ash peel or honeysuckle.It can improve capability of holding nutrient in short phase.,also it were beneficial to soil fertility,and hold back soil erosion.Sampled soil in a camphor slope,through analyzed on soil nutritive elements,like that Ca,Mg,Cu,Zn,Mn,Mo,Si,Fe,we had a deeper understanding with soil ground erosion and underground soil leaks.

通过时间对比分析，得出不同土壤利用方式下土壤养分保持能力和土壤退化的变化趋势，提出运用土壤指纹电荷方法对某一研究区域的土壤养分保持能力进行研究，可以减少研究区土壤的破坏程度，只要前期充分展开相关指纹电荷工作研究，制作图谱，后期研究则只需取少量土壤测定土壤pH值后查询前期土壤指纹电荷图谱即可得出某时段内土壤养分保持能力的变化趋势：通过对重庆南平镇石庆村人为生态恢复区不同土壤利用方式下前后一年土壤样品的分析，得出退耕后撂荒草地土壤的各项养分保持指标含量增长最快，对恢复土壤退化程度最为有利，其次是杉树林和樟树林；而从人为生态恢复的各种利用方式来看，花椒林土壤的养分保持能力最好，土壤退化恢复的程度最快，其次是金银花和桃林。
