packing of molecules 中文意思是什麼
packing of molecules
解釋
分子堆積-
The volume of a solution of a salt is generally less than the sum of the unmixed volumes of the salt and the water, because of the tight packing of water molecules in the salvation shell around the ions.
鹽溶液的體積一般都小於未混合時鹽的體積與水的體積之和，因為水分子緊密地堆積在離子周圍的溶劑化層中。 -
In the " card - packing ", a znf16pc molecule takes an angle of 52 respect to the substrate. while in the " brick - stacking ", the molecules arrange in a square lattice with lattice constant as 14. 94a and 14. 28a under room temperature and 300 respectively. from room temperature to about 150, f - ptcdi molecules follow the vollmer - weber rule when grown on quartz substrate, as revealed by afm images
在「 card - packing 」模式中，分子平面與石英襯底平面成52左右的二面角；在「 brick - stacking 」模式中，較低溫度下，分子以四方點陣平行排列，點陣常數為14 . 94 ；在300的襯底溫度下發生構象調整，點陣常數減小為14 . 28 ，分子採取更高密度的堆積方式。 -
The conclusions are as listed below : compared with absorption of fc16ab in chloroformon, the absorption peak of fcifrab in lb films shifted toward the shorter wavelength region, suggesting that some interaction among molecules due to the close molecular packing such as h - aggregates in the lb films. comparing uv - vis spectra of fc16ab in lb films deposited from cl - subphase with from aqueous subphase, this blue shift phenomenon of absorption demonstrated cl - made the compactness of fc16ab lb films increasing. ft - ir spectra of fc16ab in lb films at different temperature showed that there is a gradual disordering of alkyl chain from 27 ? to 200 ?, but no district phase transition appeared
結論如下：紫外-可見光吸收光譜說明：與fc _ （ 16 ） ab氯仿溶液相比， lb膜的吸收光譜發生了藍移，這歸結于fc _ （ 16 ） ab發生了h -聚集以及抗衡離子可以使fc _ （ 16 ） ab的lb膜排列更緊密；變溫紅外光譜說明，隨著溫度升高， fc _ （ 16 ） ab的lb膜中烷基鏈的有序排布程度減弱，這表明該lb膜熱穩定性減弱，但在減弱的過程中沒有出安徽人學申請碩士學位論文摘要現相轉變。 -
Polymer networks have been produced in a variety of liquid crystal phases in cells without surface treatment. the liquid crystal / monomer mixtures are prepared using a ferroelectric liquid crystal and a diacrylate monomer. the polymerisation of the monomer is carried out by uv curing the mixture when it was kept in a specific phase which can be obtained by controlling the temperature of the ferroelectric liquid crystal. both the monomer and the polymer network will depress phase transition temperatures. the effects of the polymer network on the packing arrangement of the ferroelectric liquid crystal molecules are examined by means of optical microscopy. the molecular packing arrangement of the ferroelectric liquid crystal in a specific mesogenic phase is frozen on the formation of a polymer network in the ferroelectric liquid crystal in that phase. the existence of the diacrylate based polymer network can improve the electrooptical switching of the ferroelectric liquid crystal
在灌裝于未經表面處理的樣品盒內處于不同狀態的液晶中制備聚合體網路.液晶/單體混合物由鐵電液晶和雙丙烯酸單體製成.單體的聚合通過維持該混合物處在一定的液晶態的條件下經紫外線固化來完成.不同的液晶態可通過控制鐵電液晶的溫度來獲得.雙丙烯酸單體或聚合體網路的存在會導致鐵電液晶載體的相變溫度降低.通過光學顯微鏡可觀察聚合體網路對鐵電液晶分子組合排列的影響.結果發現:在某一液晶態中鐵電液晶分子的組合排列可被在該液晶態中聚合而成的聚合體網路所穩定，雙丙烯酸基聚合體網路的存在可改良鐵電液晶的電光開關特性 -
In the packing of amphiphilic molecules, like units of the molecules interact with each other, i. e., the polar units associate with each other ; likewise, nonpolar unites associate to form hydrocarbon layers in the lamellar packing
在層狀相中雙親分子的堆積類似於分子單元間的相互作用，即極性基團與極性基團締合形成親水層，而非極性基團之間締合形成疏水層。 -
