Therrnogravimetric analysis at heating rates 5, 10, 15 and 20 c / min was used to study the decomposition kinetics of the pdms / pma ipn in ni and in air by using tg and dtg, and the upper limit of the temperature was 700 c. it was found that ipn began to decomposite at 350 c. the process of the thermal degradation was multiple steps, the curve of the rate of thermal decomposition had two peaks, one of which lied between 400 c ~ 420 c and the other lied between 500 c ~ 540 c, the result corresponded to the components of ipn
在熱分解動力學研究中，通過在兩種氣氛中，分別以5 、 10 、 15和20 min四種升溫速率條件下，採用tg - dtg聯動測試， ipn材料在350開始熱分解。熱分解速率存在兩個峰值，一個分解峰值在400 420之間，另一個在500 540之間，這與ipn結構中包含兩組分相對應，同時發現當緩慢升溫時，特別是在空氣氣氛中，兩個分解峰減弱，熱分解趨向於一個連續過程。 -
It is interesting that pma plus calcium ionophore a23187 can inhibit pma - induced pta1 expression, and this effect ca n ' t be reversed by calcmeurin inhibiter fk506. pta1 mabs can inhibit ctl activation and differentiation in mixed lymphocyte culture system when added at the beginning of the culture but can induce platelet activation and aggregation in the fc dependent manner. in 1997, pta1 cdna was cloned from cdna library of tpa activated jurkat cells, which belongs to immunoglobulin superfamily ( igsf ) with two v - like domains of extracelluar region of pta1
