Linear CO desorbs earlier and quicker than twin and bridged CO with the progressive heating from 25 to 300°C at 0.1MPa, and the three types of adsorption disappear at 265℃.At 205℃ the adsorption amount of linear CO and bridged CO increases with the pressure from 0.1 to 3.0MPa, but the adsorption amount of bridged CO is more than that of linear CO. At 0.1MPa and 25℃, CO2can decompose into CO and then CO adsorbs quickly, namely, CO2→CO+O, but the wave numbers of the adsorptive CO from decomposed CO2 are different from the pure CO, which demonstrates the effect of on CO adsorption. With the pressure of CO2 from 0.1 to 3.0MPa at 25℃, the total adsorption amount increases and the band at 2052cm^(-1) shifts towards higher frequency.

压力保持0.1MPa，温度由25℃升至300℃时，线式比桥式先脱附，至265℃时，3种吸附基本脱附完全；当温度维持205℃不变而压力逐步由。0.1升至3.0MPa时，线式吸附增量较少，桥式吸附增量较多，CO2在0.1MPa，25℃时就能发生快速的解离吸附，即CO2→CO+O，其吸附行为表现为CO的线式吸附，但吸附峰与纯CO吸附时不同；当温度稳定在25℃而压力逐步升至2.5MPa时，不仅CO2吸附量增大，而且其2052cm^(-1)吸附峰有向高波数移动的趋势。

People are particularly stressed out right now, and often emotional stress turns to physical stress, which turns to worse posture, which turns to pain, which turns to more stress, says Wendy Young, a certified ergonomist in Houston and author of the e-book, getinsideyourcomfortzone.com.

After gravity dehydration, the sludge almost losses its mobility. With the filter belt press forward, the space between gradually reduced, the material began to receive a slight increasing pressure. Wedge-shaped area's role is to extend the gravity dehydration time, increase the stability of the floccules, to prepare for entry into the pressure zone.

重力脱水后的污泥流动性几乎完全丧失，随着带式压滤机滤带的向前运行，上下滤带间距逐渐减少，物料开始受到轻微压力，并随着滤带运行，压力逐渐增大，楔形区的作用是延长重力脱水时间，增加絮团的挤压稳定性，为进入压力区做准备。

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。
