Kinetics of methanol dehydration to dimethyl ether on modified kaolin catalyst was studied in an integral reactor under normal pressure. It is deduced that the surface reaction of methanol molecule adsorbed on the active site of catalyst with methanol molecule in gas phase is the rate determining step. The hyperbolic type kinetic equation r=ksbMpM2/(1+bMpM+bpE) is obtained according to the theory of langmuir even adsorption and using the R-E mechanism.

采用积分反应器，考察了常压下在改性高岭土催化剂上甲醇脱水生成二甲醚的反应动力学，根据Langmuir均匀吸附理论，采用R-E机理，推断吸附的甲醇分子与气相主体中的甲醇分子发生的表面反应为速率控制步骤，得到双曲线型动力学方程为： r= ksbMpM2 /(1+bMpM+bpE)（r为反应速率， ks为反应速率常数， bM为甲醇的吸附平衡常数， b为二甲醚和水的吸附平衡常数之和， pM、 pE分别为甲醇、二甲醚的分压）。

Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.

光镜下H-E染色切片中腺上皮区仅可以区分出四种类型的细胞：弱嗜碱性纤维样细胞、强嗜碱性纤维样细胞、嗜酸性颗粒分泌细胞和纤毛细胞等；腺上皮下的基底膜区有少量结缔组织存在；扫描电镜下可以观察到鳃下腺表面的纤毛及腺细胞的分泌物等情况；透射电镜下观察到腺上皮中有支持细胞、感觉细胞和7种类型的腺细胞；近基底膜区观察到富含粗面内质网的细胞；基底膜间为薄层疏松结缔组织，内含肌细胞及神经末梢等结构。

From the viewpoint of logic of relation, syllogism is not the inference based on Relation A, E, I, O between general term and general term as Jan Lukasiewicz thought. In stead, it is the inference based on the identical relation or non-identical relation between member of class and member of class.

从关系逻辑的观点看，三段论并非如卢卡西维茨所认为的那样是根据普遍词项的A、E、I、O关系所进行的推理，而是根据类的分子与类的分子的等同于或不等同于关系所进行的推理。
