MethodsThis study was carried out in 1 500 patients with colonic polyps(n=3 875) who underwent colonoscopic resection combined either with hot forceps,snare or snare after submucosal injection.

Coordination of Si and Al in the thermal activation and gelatification of gangue;

Research on thermal activation process of coal gangue;

This paper carries out a systematic pilot study on the process of the thermal activation of coal-gangue and its influential factors under different conditions, reviewing the effects of such factors as calcining temperature, particle diameter form, detention time and cooling mode have on the activation of coal-gangue.

Preliminary studies on beat resistance and heat activation of spores of Micromonospora olivoasterospora M-41;

The research works focused on the main factors of affecting the thermal activities of PEG?the mechanical properties of treated fabrics and the objective valuation in the synthetical properties was given.

We also discussed the changes in thermal activities before and after crosslinking reactions and the thermal activities affected by the thermal stability of PEG during the curing process and by the molecular weight of PEG .

Using XRD and DTA,studied hydrothermal activity and hydrothermal products of synthesized CMS, CFS and C 3MS 2.
