The aggregate density of rod - aggregate structure is also calculated on the basis of a common presumption 在線性假設(shè)條件下,利用此判據(jù)進(jìn)行的理論分析與實(shí)驗(yàn)結(jié)果吻合。
The analysis of ir spectrum and melt flow index showed that the composite had a micro - crosslinking structure , and the analysis of dsc discovered there was - spherulite in the aggregate structure of the composite of pp 紅外光譜分析和熔體質(zhì)量流動(dòng)速率的測(cè)定表明,復(fù)合材料體系產(chǎn)生了微交聯(lián); dsc分析發(fā)現(xiàn), pp材料的聚集態(tài)結(jié)構(gòu)中含有球晶。
A new type of structure of the solid - stale displacement reactions which named spiral - mtergrowth - aggregate structure was discovered in the mo2c - si diffusion couple and was considered as the result of spinodal - decomposition continuous phase - transformation 昆明理工大學(xué)博士學(xué)位論文2002 . 5摘要6 .初步發(fā)現(xiàn)了一種新的固態(tài)置換反應(yīng)形貌結(jié)構(gòu):螺旋共生束集型結(jié)構(gòu)。
3 . the multiwalled carbon nanotube ( mwcnt ) bonded by 2 , 9 , 16 , 23 - tetra amino manganese phthalocyanine ( tamnpc ) was obtained and both its chemical and aggregated structures were characterized by means of ftir , uv - vis , tem , and xrd 3 .成功合成了以化學(xué)鍵合方式連接的四氨基酞著錳一碳納米管分子內(nèi)復(fù)合光電導(dǎo)材料體系,并用ftir 、 uv - vis 、 tem和xrd等手段表征了其化學(xué)結(jié)構(gòu)和聚集態(tài)結(jié)構(gòu)。
