New type of liquid crystals such as laterally fluorinated naphthalene indane , axially fluorinated cyclohexane and liquid crystal containing highly fluorinated substituent , which with high negative dielectric anisotropy low viscosity and high clearing point were emphasized 重点介绍了近年来开发出的一些具有大的介电各向异性、低黏度、高清亮点的新型液晶，如侧向氟取代萘环、茚环类，轴向氟代环己烷类，含多氟取代类液晶等。
This pre - processing method not only removes noise from the spectrum , but also filters the irrelevant information from response matrix . in the second part of this thesis , the nicotine and total - sugar content of tobacco and benzene / methylbenzene / cyclohexane / ccl4 solution system was corrected by osc combined with pls Osc校正法在对原始数据进行滤波时，可确保滤除的信息与待测信息(浓度等)无关，因而优于传统的数据处理方法。
Abstract : the uv absorption spectra of magnetized acetone ( cyclohexane as solvent ) is determined separately at different magnetization time and different time for placement after magnetization by uv - spectrophotometry . it was found that magnetization effect could be saturated and continued . furthermore , the different magnetization time made the strength of absorption change at various degrees . when acetone was placed after magnetization , the magnetization effect not only disappeared , but increased in a period of time 文摘:作者研究了丙酮环己烷溶液磁化前后、不同磁化时间以及磁化后放置不同时间的紫外光谱，发现有磁饱和现象与较长时间的磁化效果存在，这对于研究磁场影响化学反应的机理提供了实验依据。
( 3 ) pbs nanotubes , cac2o4 nanowires and caco3 nanometer whiskers were first synthesized in the bicontinuous microemulsion containing non - ionic surfactant op / n - pentanol / cyclohexane / aqueous solution . in those processes , the nanosized aqueous channels in the bicontinuous microemulsion were used as sofe templates ( 3 )采用op正戊醇环己烷水溶液所形成的双连续微乳液中的“隧道”作软模板，合成出了pbs纳米管、 cac _ 2o _ 4纳米线、 caco _ 3纳米须等不同形貌的纳米粒子。
Experimental data agreed with those calculated the compositions of musks in the equilibria liquid phase were different from the feed , that is , musk ketone was richened in dimethyl sulfoxide ( or acetonitrile ) phase while musk xylene was richened in heptane ( or cyclohexane ) phase 平衡双液相中两种麝香的比例不同于原料，两液相中两种麝香分别得到了富集，其中二甲基亚砜（或乙腈）相中富含酮麝香、庚烷（或环己烷）相中富含二甲苯麝香，这种液相分相可用于分离麝香混合物。
Abstract : six quasi - ternary liquid - liquid equilibria systems between benzene , toluene , p - xylene , n - heptane , methyl - cyclohexane and n - formylmorpholine ( nfm ) + water have been determined at normal pressure and 60 ; the conjugate phase compositions and the contribution curves of these quasi - ternary liquid - liquid equilibria systems were obtained ; the experimental data were correlated using uniquac and nrtl models ; the plait points of these systems were obtained by the constructive fitting for the conjugate phase and parameter predicting methods ; the selectivity and contribution coefficients of the solvent to the solutes were calculated 文摘:用液液平衡釜测定了常压， 60下加水n -甲酰吗啉和苯、甲苯、对二甲苯、正庚烷、甲基环己烷组分间6个拟三元体系的液液平衡，得到了拟三元液液平衡体系的共轭相组成和分配曲线；实验数据用uniquac和nrtl模型进行了关联；用共轭相作图拟合法和模型参数推算法获得了各体系的褶点数据；并求得了溶剂对溶质的选择性和分配系数。
The neutral bio - oi1 can be separated into three fractions : the fraction washed down by cyclohexane ( c1 ) mainly contains aromatics with up to four rings ; the fraction washed down by benzene ( c2 ) mainly contains alkyl - substituted aromatic hydrocarbons and polyphenols ; and the fraction washed down by methanol ( c3 ) mainly contains ester polar components 中性油层析分离为3个馏分：环己烷洗脱馏分( c1 )主要为四环以下纯缩合化合物；苯洗脱馏分( c2 )主要由单环烷基芳烃和多酚组成；甲醇洗脱馏分( c3 )主要是酯类极性化合物。
Correspondingly , xrd patterns revealed that carbon shells became graphitic somehow . the effects of organic solvents and catalysts / catalysts precursors on the structure and morphology of products were also investigated in this study . cyclohexane , instead of benzene , was proven to be a suitable solvent , as it would not pyrolyze in the reaction system 对金属催化剂(或前体)以及有机溶剂与产物形貌关系的研究结果表明，苯作溶剂在反应条件下易裂解并形成积炭，从而阻碍了多孔碳产物的继续生成，而选用环己烷可以避免类似的裂解反应。
We can see from the photos of the sem that the diameters of the powers of this tree land of materials obtained by the system of trion x - 100 / caprylic alcohol / cyclohexane / water are about 20 nm . by means of uv - vis , atomic absorption spectrometry and so on , nanoparticles of this three kind of anode materials are synthesized 利用trionx - 100 /正辛醇/环己烷/水反胶束体系制备出三种物质的粉体，扫描电子显微镜照片显示粒子的粒径在20nm左右，分布均匀；此外还利用uv - vis 、原子吸收光谱等测试手段，都表明合成出了三种正极材料的纳米粒子。
