A new cinchonine ion selective electrode was prepared by dipping the Ag/AgCl electrode into the sol-gel solution for more than 3 times, and then standing for 48h at room temperature, and finally activating for at least 12h in a 1.0×10^(-2)molL^(-1) cinchonine solution.

The fluorescence anisotropy using steady-state fluorescence polarization method was measured for the solution of β-CD and cinchonine mixed and sonicated for 1h. The anisotropy values for the solution increased with the increase of the concentrations of β-CD, which implied the existence of some complexes of large size or nanotube structure. Many type of large size complexes formed between β-CD and Cin under high concentrations in gas phase were characterized by ESI-MS in moderate experiment conditions.

将辛可宁与环糊精的混合溶液超声1个小时后，用稳态荧光偏振方法测定溶液的各向异性值，发现随着环糊精浓度的增大，溶液的荧光各向异性不断增强，这意味着溶液中形成了大尺寸即纳米级结构的环糊精与辛可宁复合物；用温和的质谱测定条件表征发现高浓度的β-CD与辛可宁在气相中可形成各种类型的大尺寸复合物。

When scaled factor circulant matrices are nonsingular, we can find the single solution of the scaled factor circulant matrix equation; When scaled factor circulant matrices are singular, we can find the special as well as the general solution of the scaled factor circulant matrix equation; There is only an error of approximation when the fast algorithm is implemented on computers, and only the elements in the first row of the scaled factor circulant matrix and the constants in the diagonal matrix are needed by the fast algorithm.

当鳞状因子循环矩阵非奇异时，该快速算法求出线性方程组的唯一解；当鳞状因子循环矩阵奇异时，该快速算法求出线性方程组的特解与通解。该快速算法仅用到鳞状因子循环矩阵的第一行元素及对角矩阵中的对角上的常数进行计算。在计算机上实现时只有舍入误差。

论文摘要：本文讨论了任意伏安特性电阻元件满足的基本微分方程以及非线性电路的功率匹配问题的几个定理，指出任意伏安特性电阻元件均满足非线性一阶的clairaut方程，并且，线性电阻元件的伏安特性是clairaut 方程通解，而非线性电阻元件的伏安特性是clairaut 方程的奇解。

But the solution of these two problem or not and the degree of the solution, have close relations with the geography humanities environment, with the civilizing of the clansmen and the education of the schools, with the whole characters of the leaders.

而这两个问题的解决与否及解决的程度，是与宗族的地理人文环境、宗族教化和文化教育、领导班子的整体素质等等三方面有着密切的关系。

Solve et coagula, the one is mutually dependent on the other, without solution there is no bonding, without bonding no solution, without hate there is no love, and without darkness there is no light.

Solve et Coagula】，相辅相成相生相克，--没有解决就没有难题，没有难题就没有解决，没有恨就没有爱，没有黑暗就没有光明。

The second was to compare the effects of the different floating liquids on the destruction of rabbit coccidia oocysts. The results indicated that magnesium sulfate solution showed the lowest rate of coccidia oocyst destruction at 20 min; saturated salt water had the greatest rate of destruction. The destruction increased with time; in the saturated salt water and urea solution damage or deformation of a few coccidia oocysts at were observed 60 min.

其二，不同漂浮液对兔球虫卵囊破坏作用比较；结果表明20min时硫酸镁溶液对卵囊破坏率最低，破坏率最大的是饱和食盐水，随着时间延长各种破坏作用增大，60min时饱和食盐水和尿素溶液中有极少卵囊破损和卵囊变形现象。

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。

Fast algorithm of minimal norm least square solution for Cauchy linear system;2. For the m×n Cauchy-type matrix with full column rank,the fast algorithm of the minimal norm least square solution to the linear system Cx=b was obtained by construction of a special block matrix and study of the triangular decomposition.

对于秩为n的m×n阶Cauchy型矩阵C，通过构造特殊分块矩阵并研究其三角分解，进而得到了线性方程组C x=b的极小范数最小二乘解的快速算法，所需运算量为O+O(n2)，而通常构造法方程组的方法所需运算量为O(m n2)+O(n3)，用正交化法虽然避免了构造法方程组，但所需的运算量更大些。
