Aiming at above problem, this paper put forward the strategy of separation as follows. Firstly, in view of great amount of coloring matter in solution, the quality of product is declined. So we decolor the solution by acticarbon, which makes 80% coloring matter be removed, but the loss of nucleotides is only about 2%. Secondly, on the basis of physical and chemical properties of four nucleotides, we first synthesized a kind of cation exchange resin by ourselves which is used to separate four matters preliminarily.

针对以上问题，本文提出了如下的分离策略：首先，由于酶解液中色素含量较多，使经树脂分离所得UMP和GMP中色素残留较多，最终导致成品质量的下降，所以我们用活性炭对酶解液进行脱色处理，使溶液中80％以上的色素被吸附除去，而核苷酸的吸附损失仅为2％左右。

Three QTLs detected for maximum adventitious root length in solution culture, total root dry weight in both solution culture and paper culture accounted for about 20%, 23% and 13% of the total variations, respectively.

其中溶液培养中的最长不定根长、总根干重和旱作培养中的总根干重检测到的QTLs位点对总变异的贡献率分别为 2 0 %、2 3 %和 13 %左右；旱作培养中的最长不定根长、不定根数、根冠比和溶液培养中的根冠比仅检测到上位性位点，对表型变异的贡献率在 12 %～ 61%之间。

In SHET, equations which represent relation of fundamental component and preparatory eliminated harmonic components are a system of nonlinear, transcendental equations that require the interative Newton-Raphson matrix method for its solution, and convergence in solution depends on whether or not starting value given is right.

特定消谐技术中，表征基波及各次谐波幅值与开关角关系的方程组为非线性超越方程组，一般只能采用牛顿迭代法等数值方法求解，而解的收敛性取决于所给初值的正确与否。

In the third area, Pb2 is gradually supersaturated in solution with the increase of pH value, so the Pb2 is deposited as sediment. As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb(superscript 2+) reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb(上标 2+)与羟基形成了配合物，主要是以Pb3的形式存在而大量进入溶液，因此，尚需进一步除铅。

The possible mechanism for the two ECL channels at the Pt electrode cathodically pre-polarized in alkaline solution is also proposed:(1) luminol anion was electroxidized to radical at 0.22V, which then reacted with the oxygen dissolved in solution and emitted light;(2) the fresh oxygen species electro- generated at 1.07V oxidized luminol anion with light emission.

同时给出了在碱性含氧溶液中预还原的铂电极上两个可能的ECL反应通道：(1)在0.22V鲁米诺阴离子氧化为鲁米诺自由基，然后与溶解氧反应而发光；(2)1.07V处析出的新鲜氧与鲁米诺阴离子反应而发光。

Structure-based mutational analysis demonstrated that replacing hydrophobic residues in the dimer interface by hydrophilic changed the aggregation behavior of the protein in solution to various degrees, which show the crystallographically observed dimer is mostly forms in solution.

这表明，在晶体结构中所观察到的二聚体是Gadd45γ在溶液中主要的聚集形式。

The magnetite with a mean diameter of 8nm was prepared by chemical coprecipitation methods. By the addition of nonionized oleic acid to the suspension of magnetite in solution during precipitation, the magnetite nanoparticles were coated with a double surfactant layer. A gel-like precipitated precursor is then formed because of the hydrophobic interaction among those coated units. By transferring of this precursor to an organic solvent, the surfactant double layer on Fe〓O〓 nanoparticles reduces to one; however, it still remains as a double layer by transferring to an alkaline aqueous solution. Both these cases give in stable colloids of superparamagnetic Fe〓O〓 nanoparticles.

从解决无机磁性Fe〓O〓颗粒与有机烯类单体的相容性入手，采用化学共沉淀法，制备了平均直径为8nm的超顺磁性Fe〓O〓颗粒，在制备过程中以非离子形式引入油酸，在Fe〓O〓颗粒表面形成一个具有双层结构的疏水外壳，并通过疏水相互作用凝聚成磁性Fe〓O〓凝胶，能够以单分子层结构形式溶解在非极性溶剂中，也能够以双分子层结构形式溶解在碱性水溶液中，形成稳定的超顺磁性Fe〓O〓溶胶。
