There are several explanations for the casimir effect . it is considered commonly that the casimir force is the macroscopic manifestation of the van der waals force between two neutral polarizable particles 对于casimir力的物理解释是一般认为它是两个中性的可极化微粒间的范德瓦尔斯力的宏观体现。
The decisive nano forces are pointed out to he van der waals force , repulsive contact force , nab frictional force , capillary force and nano electrostatic force , and their calculation formulas are also deduced 指出起主要作用的纳观力为范德华力、接触斥力、纳米摩擦力、毛细作用力以及纳米静电力等五种，并初步推导了各种纳观力的表达形式。
Because of the van der waals repulsion between two substituents existed in chiral 1 , 2 - disubstitited ferrocene , the elevation angle of partial helix in the molecular structure is changed 由于手性1 , 2 -二取代二茂铁的两个取代基之间的范德华斥力，致使其分子结构中包含的部分螺旋改变了仰角，而这种改变使有关螺旋的旋光度代数和不为零，因而导致旋光性。
By the analysis and comparison of the particles of dust flow , the main force acting on the particles of dry dust flow is van der waals force and the liquid - bridging force on the particles of wet dust flow are found 通过时尘流中尘粒受力的分析，得出在乾燥环境下作用在尘粒上的主作用力是范德华力；在湿润情况下作用在尘粒上的主作用力是液桥力的结论。
It is found van der waals forces often predominate , including interaction of permanent and induced dipoles and london dispersion forces , so the process of gust molecular into p - cd ring companies with a great deal of physic sorption 实验表明，在环糊精与客体分子的包结配位，除了主要通过尺价健间弱相互作用力的协同作外，客体分子的极性尺寸和空间构型也是影响包结的作用因素。
Some phenomena of polymer solution , which can not be satisfactorily explained by such basic chemical theory as van der waals force and hydrogen bond , are well interpreted by introducing the structrue adapability tenets of cybernetics into the branch of polymer 摘要将控制论的结构适应性原理引入高分子学科，解释了一些范德华力、氢键等化学基本理论未能恰当解释的聚合物溶解现象。
Van der waals ( vdw ) complexes are weak bonding complexes formed by atoms or molecules through interaction of electric multipole moments and dispersion forces . these complexes are characterized by their comparatively low binding energy ( 100 - 1000cm - 1 ) 范德瓦尔斯( vdw )复合物是原子或分子间通过多极矩和色散相互作用形成的弱键能复合物，它们的键能比较弱，一般为100 1000cm ~ ( - 1 ) 。
Supramolecular action is a kind of molecular interaction with molecular recognition ability . it includes van der waals and electrostatic interactions , hydrogen - bonding , - bonding and hydrophobic interaction , which are accompanied by spacial effect 超分子作用是一种具有分子识别能力的分子间相互作用,是空间效应影响下的范德华力、静电引力、氢键力、相互作用与疏水相互作用等。
Van der waals attraction , electrostatic force and capillary adhesion force are the three main forces for micron particle adhered to surface , and further research demonstrates the van der waals attraction is the most important factor to our research objects 根据理论计算，对吸附在光学基片表面上微米和亚微米级的抛光微粒，其范德华力与自身质量之比f _ v m高达10 ~ 6 10 ~ 9 ，传统的清洗方法难以克服它。
To significantly improve both strength and durability of repair interfacial layer between old and new concrete , two attempts were firstly put forward in this thesis : ( 1 ) a kind of new modified primer would be produced by introducing shrinkage reducing admixture into cement mortar , which may both reduce the shrinkage of the interfacial layer , and lessen the content of large crystal in the repaired interface layer , accordingly , remarkably increase the van der waals force of interfacial layer 为大幅度提高新老混凝土修补界面层的强度和耐久性，本文首次提出并实现两个设想： ( 1 )以国产减缩剂为外加剂，配制新型改性水泥砂浆界面剂。该界面剂既能减少界面层宏观干缩裂缝，又不增加大晶体，使界面层形成密实的微细观结构，显著提高粘结界面层内晶体间的范德华力。
