spherulite 中文意思是什麼

在球晶的表面出現有同心圓環狀條紋，經實驗驗證為表面的不平整所導致，形成機理主要可能是結晶過程中的體積收縮。

A reasonable mechanism of the concentric ring like patterns on the surface of phbv spherulite was given first. the segregation of hv content between cystal and amorphous parts was observed and the phenomena caused were discussed

首次對phbv球晶表面觀察到的同心圓環條紋的成因作了合理解釋，揭開了這一現象形成的本質。

The sgr ( spherulite growth rate ) of phbv is related to crystallization temperature. with the increase of temperature, sgr increase first then decrease. some sample ' s sgr will increase again at high temperature area

Phbv的球晶生長速度與時間無關，隨溫度的升高有先上升後下降的趨勢，部分樣品在最後球晶速度會再次上升。

And the spherulite growth rate of phbv is studied and the factors, which influence the growth rate and the formula of spherulite growth rate, were discussed

並通過對phbv球晶生長速率的測定，對結。晶生長的速度方程及影響因素做出修正。

The results of linear regression indicate that the addition of pam do not alter the avrami exponents, about 2 - 3, which suggests that the crystallization modes might be a mixture of three - dimensional spherulite and two - dimensional circular

Avrami方程線性回歸結果表明聚甲亞胺的加入對體系的avrami指數n影響不大， n值約在2 3之間。

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量流動速率的測定表明，復合材料體系產生了微交聯； dsc分析發現， pp材料的聚集態結構中含有球晶。

The polymerization kinetics of pam, the feeding pattern of the initiator naoh and a method used to characterize the spherulite morphology of monomer casting nylon were investigated. the mechanics of inhibition of pam to the polymerization of nylon was certificated by means of a series of experiments

通過兩個體系的pam pa - 6復合材料的力學性能、 sem 、 xrd 、 dsc和tem等測試方法研究復合材料的結構與性能間關系，表明聚甲亞胺端基對復合材料性能有一定的影響。

The results from x - ray diffraction demonstrated that pp / mmtome was a fully intercalated nanocomposite, pp / mmtom and pp / ommt were partly intercalated nanocomposites, but the intercalation effect of pp / mmtom nanocomposite was better ; the crystallization characteristics of pure pp and pp / mmt nanocomposites were investigated by dsc, waxd and pom. the result of these testing showed that mmt nano - layers acted as nucleating agents for the crystallization of pp, the addition of mmt had effect on the crystallization process, leading the increasing of crystallization temperature crystallization rate and crystallinity, but also the dimension of spherulite reduced. but the formation of pp crystal did n ' t change, the formation of pp crystal in three pp / mmt nanocomposites and pure pp were a - form on the whole ; influences of three sorts of mmt on mechanical properties of pp / mmt nanocomposites were studied, as a result, the addition of mmt comprehensively improved mechanical properties of pp : notched impact strength, tensile strength and flexural properties were all increasing, but the extent of increasing were n ' t large

通過xrd分析比較這三種pp mmt納米復合材料微觀結構得到， pp mmt _ （ ome ）屬于完全插層， pp mmt _ （ om ）與pp ommt的插層程度相近，但是pp mmt _ （ om ）相對較好；通過對純pp和三種pp mmt納米復合材料的結晶性能研究發現，蒙脫土納米片層對pp結晶產生明顯的異相成核作用，結晶能力增強，使pp的結晶溫度和結晶速率提高，結晶度增加，球晶晶粒細化，但是沒有改變pp的結晶形態，三種pp mmt納米復合材料的結晶形態都屬于晶；通過對pp mmt納米復合材料的力學性能測試得知，蒙脫土的加入全面提高了pp的力學性能，缺口沖擊強度、拉伸強度和彎曲性能都有一定程度的提高，浙江{ _業大學碩十學位論文摘要但是提高幅度都不是很大，不過ommt 、 mmtom和mmtc ） me三種蒙脫土對pp力學性能有著不同的改性作用，其中pp / mmtom最好， pp月邊mto崛次之， pp / ommt最低，這種情況主要是由蒙脫土對pp結晶性能的影響和蒙脫土的納米改性作用造成的。
