In the study of non-isothermal crystallization kinetics, we found that the Avrami constants were enhanced with the increase of the amount of the modified MMT at 10 ℃/min and 30 ℃/min. But it decreased with the increase of the amount of the modified MMT while the cooling rate increase to 50 ℃/min. The crystallization rate constat k also increased with the increase MMT and it revealed that the crystallization rate of composites accelerated by the presence of MMT.

由非等温结晶动力学得知，复材之Avrami 常数n值在10℃/min与30℃/min时，会随著改质蒙脱土含量增加而上升，但是当降温速率提升至50℃/min时，则随著改质蒙脱土增加而下降，其结晶速率常数k值随著改质蒙脱土含量增加而上升，代表复材之结晶速度也会受到添加改质蒙脱土的影响而变快。

Choose medicaments correctly, reasonable use medicaments, in order to make sure with medicine safety is mixed effective will be henceforth the main task that clinical medicine learns, for solution control hospital the clinical current situation that use drug reachs existence issue, promote the development of the reasonable job that use drug, raise a hospital reasonable the level that uses drug, the prescription of two place has outpatient service of author general hospital, be in hospital analytic research, summary goes out unreasonable a few big states that use drug, undertake classified at the same time. 1 clinical unreasonable with medical analysis each division all applies 1 abuse of 1 · or antibiotic of blind application antibiotic extensively, utilization rate amounts to 70% above, among them couplet is used rate be as high as 40%, appear even 2 couplet, triplex above, the commonnest abuse is infection of the upper respiratory tract, be admitted to hospital give 2~3 to plant antibiotic cure. 1 · of 1 · 1 without point to this kind to the cure that ask for uses drug unreasonable with medicine main show is in the person that the virus sex appeal such as hepatitis of sex of common cold, chicken pox, berpes zoster, virus is caught, in infection of not amalgamative bacterium, point to without what apply antibiotic ask for next using medicine. Incontrollable virus affects antibiotic, increase hepatic burden instead to patient of virus sex hepatitis.

The Ca2+ salt solution as a new regenerant was presented in this paper. The influences of the calcium salt proportioning, temperature, dosage and flow rate on anion exchange fiber regeneration were studied. High regeneration can be obtained with 0.5 mol/L CaCl2+8 g/L CaO+6.5 °Bx sucrose solution at 70～80 ℃, the dosage of the Ca2+ salt solution was about half of the raw decoloring syrup, the regenerant flow rate should be lower than that of the raw decoloring syrup. It was shown that stable decolorization rate and lower decline in exchange capacity could be achieved with the new regenerant. It performed more effectively than the traditional sodium salt regenerant with less discharge of waste water.
