The pugging process experiment of silica brick pug was made in Φ1 600×450 wet pan mill to study the change rule of main component mixing homogeneity and molding performance of the pug. The results showed that the pervasion and mixing concurred when diversified materials acceded to the wet pan mill, prolonging time in dry-mixed and wet-mixed periods had no action for increasing mixing homogeneity with pugging time prolonging, the molding performance was improved and the porosity of silica brick adobe had downtrend, but prolonging time after pugging 14 min the effect was not remarkable.
通过对Φ1 600×450湿碾机混练硅砖泥料过程中泥料主要成分的混合均匀度、泥料成型性能的变化规律研究,发现在各种物料加入湿碾机时,同时存在着扩散混合作用,延长干混、湿混阶段的时间,对于提高混合均匀度实际上没有意义;随捏练时间延长,泥料成型性能改善,砖坯气孔率呈下降趋势,但捏练14 min以后继续延长捏练时间,采用正常压制制度时,砖坯气孔率降低值已经很小。

The results showed that with the increase in the mined area grade of leaf by miners, the photosynthetic rate, stomatal conductance, transpiration rate and stomatal limiting value in castorbean Ricinus communis and kidney bean Phaseolus vulgaris generally decreased. Positive relations existed in the above two crops between different treatment grades and intercellular CO2 concentration variation.
结果表明,随着叶面积受害级别的增高,蓖麻和菜豆的光合速率、气孔导度、蒸腾速率和气孔限制值总体呈下降趋势,不同受害级别与胞间CO2浓度的变化呈正相关。

Under light water stress, the main reason is the stomatic limitation; under heavy water stress that is nonstomatic limitation.
轻度水分胁迫(SRWC在60%~40%)下,气孔限制是Pn下降的主要原因;严重水分胁迫(SRWC在40%~20%)下,Pn的下降主要是非气孔限制的结果。

The results showed that, under the condition of soil water stress during the flowering stage of potato, the daily changes of net phoTo,synthetic rate, transpiration rate and stomatic conductance were parabola type.
结果表明,在马铃薯生育关键期土壤水分亏缺情况下,4种处理叶片净光合速率、蒸腾速率和气孔导度的日变化曲线均为开口向上的抛物线,而净光合速率日变化是气孔调节作用的结果。

It was possible that the direct transport of JA from unwounded tissue to wounded site could account for the increase of JA after leaf wounding.
用免疫荧光显微镜技术和免疫胶体金电镜技术证明JA在蚕豆叶片下表皮和气孔保卫细胞上是普遍存在的,它主要分布在保卫细胞的叶绿体、细胞核和细胞壁上;叶片的局部灼伤可提高JA在质外体和气孔保卫细胞中水平。
