The balance pressure of water vapor during hydration processes of partially magnesium chloride was calculated.

摘要对低水合氯化镁的吸水过程进行了初步的探讨,并对低水合氯化镁吸水过程中与水蒸气的平衡分压进行了计算。

The effects of NaAA content on the mechanical properties and water-swellable properties were studied. The experimental results show that NaAA has good reinforcement for the EVM vulcanizate. EVM vulcanziate reinforced by NaAA has higher water absorbing rate and equilibrium water absorbing ratio. When the NaAA content is 50 phr, the maximum water-absorbing ratio of EVM vulcanziate is 278.3%. With the incorporation of ion into immersing media, the water-absorption ratio of EVM vulcanizates decreases. FT-IR analysis confirms that NaAA formed in the process of compounding and underwent polymerization during vulcanization.

结果表明,NaAA对EVM硫化胶具有明显的增强效果;NaAA原位改性的EVM硫化胶具有较好的吸水膨胀性能,NaAA用量为50phr时,最高吸水率为278.3%;浸泡介质中离子的引入使EVM硫化胶的吸水率下降;FT-IR分析表明,在混炼过程中生成了NaAA,在硫化过程中NaAA发生聚合反应。

The CPE/LiAA and CPE/NaAA compounds have good curing properties. The tensile strength is about 30MPa when the in situ formed LiAA or NaAA content is 30phr.

其混炼胶的硫化速度快、硫化程度高;当其含量为30份时,硫化胶拉伸强度可达30MPa左右;硫化胶吸水膨胀速度快,浸水24小时后原位合成LiAA和NaAA改性CPE硫化胶的吸水膨胀率分别可超过120%和85%。

Based on the water and fertilizer coupling experiment in corn field,one-dimensional soil moisture content model containing the water uptake corn roots is used in this paper to simulate the evapotranspiration and the water uptake of corn roots and the change of soil pondage and soil moisture budget under the different water and fertilizer coupling conditions in corn field.

结果表明:在玉米生长初期以棵间蒸发为主,其后则是以植株蒸腾为主;玉米在30~40 cm土层吸水速率达到最大值;玉米灌水量为田间持水量的70%与85%对土壤0~80 cm土层贮水量的贡献是相等的,并且高肥力在一定程度上可增强根系的吸水能力,高灌水可增强玉米根系对养分的吸收利用,但对于提高水肥利用率来说,理想的处理为中肥中水。
