(1) The product was recrystallized by non-polar or low-polar solvent.

(2) We know that it's non-polar.

(3) This method is applicable not only to non-polar and slight polar liquids, but also to strong polar and associated liquids.

(4) The alkanes are non-polar.

(5) The solvents are grouped into non-polar, polar aprotic , and polar protic solvents and ordered by increasing polarity.

(6) Addition of collector or non-polar oil emulsion to extremely fine mineral suspension can intensify induction of hydrophobic flocculation of extremely fine mineral particles, forming floc.

(7) According to the distribution characteristics of polar and non-polar aro- matic compounds, analysising Liquid chromatography of reservoir core sample, can identify reservoir water bearing properties.

(8) By using a non-polar column separation, the equilibrium conditions for the determination of residual solvents in edible vegetable oils by headspace gas chromatography (HSGC) have been developed.

(9) Magnetics are by definition polar. Crystalline energy is non-polar, zero point !

(10) Most non-polar deserts are hot because they have little water.

(11) The mechanism of intensifying action of non-polar oil on hydrophobic flocculation is connection of "oil bridge" and increase of hydrophobicity of particle surface with spread of oil droplet.

(12) This is more pronounced in polar liquids than in non-polar liquids.

(13) The adhesive had good workability, high compressive strength and better bonding strength for polar materials, for example iron, and non-polar materials, for example PE.

(14) Flame retardant of aluminium trihydrate must be modified to improve the compatibility with non-polar polymer.

(15) Turf roots in a bad growth condition. There are overfull non-polar sites on hydrophobic soil particles. Soil was polluted from overusing of pesticides and fertilizers.

(16) There are correlations in responsibility with blood compatiblilty of biomedical materials and responsibility with intelligent behavior of adhesives suiting for both polar and non-polar substrates.

(17) The exit of combat troops does not end the post-1990, non-polar disorder that Hussein's invasion launched.

(18) Reverse micelle is a hydrous polymer that has a contrary structure to the normal micelle[http:///non-polar.html], it is formed by surfactant solving in non-polar solvent.

(19) There are strong intra-molecular hydrogen bonds for those molecules that are difficult to form hydrogen bond in non-polar solvents.

(20) Polypropylene (PP) is one of the most promising thermoplastic polymer. However, the use of polypropylene has been restricted because it is a kind of non-polar polymer.

(21) The work consists of three parts:(1)Investigating the conformation changes of Candida antarctica lipase B (CALB) in several polar and non-polar organic solvents by molecular dynamics simulation.
