Batch sorption and desorption experiments were employed to investigate the desorption hysteresis of phenanthrene as a model compound at different initial concentrations and different sorption time using natural soils.

Cultural resources have three Characteristics: potentiality,hysteresis and unity.

By means of XRD analysis, P-C-T test method, the effects of Ni partially replaced by Fe, Cr, Cu, Co and Mn elements on the structure, hydrogenation-dehydrogenation characteristics, hysteresis and kinetics were studied systemically.

Within over twenty years,the economic benefits of individual trees panting is not available owing to the lagging policy,which limits on the advantage of regional economy and slow.

The delay and reform of physics teaching method of normal university on a background of new curricula standard;

This paper discusses that the delay of accounting standard of earnings management leads to a serious distortion of accounting information and greater efforts should be made to guard against distortion of accounting information.

Temperature hysteresis quality of the wax-type thermal element is the major factor to affecting Automatic Star.

The fitted n values in the Freundlich equations corresponding to the sorption stage were larger than those corresponding to the subsequent desorption stage, suggesting a significant hysteretic desorption of chlorotoluron in tested system.

The professional course of Cuisine Technology and Nutrition has a lot of characteristics of its own compared with other specialized courses,for example,involvement of many related subjects,theoretical knowledge being obviously periodical and hysteretic,and a clear gap between the difficulty of the teaching materials and students\' actual level.

Because of the bolted joints between the elastic body and the pressed body in this kind of load cell, the contact between them will have serious influence on the load cell hysteresis.
