The gasification of beisu , shenfu , xinzhou and luan coal chars with co2 at 970 ~ 1165 was studied by the isothermal thermogravimetric analysis ( tga ) under the condition of chemical reaction control 摘要考察970 ~ 1165 ，北宿、神府、忻州、潞安煤焦与co2在热天平中的气化反应，用恒温法进行热重分析，考察煤种、气化温度、灰分对煤焦气化的影响。
Its bend strength is 144 . 1 mpa , impact strength is 13 . 5 kj / m2 and martin heat - resistant temperature is 160 . and the heat decompounding temperature of the resin is 350 , which is confirmed by the tga of cured resin 同时对改性后树脂固化物进行热失重分析，确定树脂固化物热分解温度为350 。表明通过改性后的双马树脂具有较好的力学性能和耐热性。
The thermal stability of the nanocomposites was characterized by thermo - gravimetric analysis ( tga ) the results showed that the solvent remained in the specimen prepared according to dissolve intercalation process changed the thermal performance seriously 通过热重分析( tga )测试发现，溶液插层法制备的试样中残留的溶剂对复合材料的热性能影响很大。
The morphology , composition and crystalline of the composite particles were characterized by scanning electron microscopy ( sem ) , x - ray diffraction ( xrd ) and thermo - gravimetric analysis ( tga ) techniques 利用扫描电子显微镜( sem ) 、 x -射线衍射分析( xrd )和热重分析( tga )对复合微球的形貌、无机沉积物cds的晶型和有机-无机成分相对含量等进行了表征。
Dta / tga analysis indicated that the perovskite pmn - pt could be formed at 650 . and the loss of pbo would be sharply increased from the temperature of 1200 . the perovskite pmn - pt was heat - treated under various temperature from 650 to 1200 Dta tga分析结果表明： pmn - pt体系在650就开始形成钙钛矿相，在1200的条件下， pmn - pt钙钛矿相会有少量的铅挥发。
Phylogenetic tree indicates the rab protein may play a role in vesicular trafficking from endoplasmic reticulum to golgi body . two tga in eo - rabl were successfully mutated to tgc by site direct pcr procedure and the truncate eo - rabl was obtained 以此重组质粒为模板进行pcr定点突变，将eo - rab1基因中前两个tga突变为通用半胱氨酸密码子tgc ，获得截短型eo - rab1基因。
