During the synthesis of Y type molecular sieve with oriented additives, the content of SiO_2 and Na_2O remained in crystalline spent liguor is high, which is equal to dilute soluble glass of low modulus. 在导向剂法合成Y型分子筛的工艺下,晶化母液中残留的SiO2和Na2O的含量比较高,相当于模数较低的稀水玻璃。
Molecular chain arrangement of directional PMMA is ordered and oriented, so mechanical properties of directional PMMA are improved greatly compared with PMMA. And the improvement of mechanical properties is relative with the aggregation structure. 由于定向有机玻璃的分子链变为有序的定向排列,故其综合力学性能与非定向有机玻璃相比得到了极大的改善,力学性能的改善程度与其聚集态结构有关。
The analysis of XRD for PI sheaf shows the transit of the microstructure of PI film from super molecular lamellar structure to the random state, and then to highly oriented graphite with the increment of heat treatment temperature. XRD分析表明PI薄膜热处理过程中会发生从高分子定向(MO)膜到无定型炭,再到高有序石墨结构的转变。
Molecular conformation : describe how functional groups bonded to the central fused rings system are oriented with respect to the central plane. 一个晶体大菜鸟请教各路的大虾们指点我该如何描述官能团(取代基)和中心环平面的定位关系。
The possible molecular mechanism of the interactions is that sulphonate group is located in the polar region, and A-ring is oriented to the hydrophobic core while the aromatic ring is near the glycerol backbone and carbonyl groups of DPPC liposomes. 它们作用的分子机制可能是,磺基在脂质体的极性区,A环朝向其疏水区,而芳香环处于磷脂的甘油骨架和脂酰基附近。
