Based on conditions on the conjugate quadrature filters constructing the orthogonal scaling function and wavelet, the orthogonal conditions were designed as an objective function which was minimized by the parameter optimization in the parameterized formula of complex conjugate quadrature filters. The compact support, symmetry, quasi-orthogonal filters and wavelets were obtained.

Methods One hundred and six eyes of 56 patients were divided into three groups: mild myopia (-0.50~-3.00 D), moderate myopia (-3.25~-6.00 D) and high myopia (-6.25 D~) based on measurement with autorefractor in cycloplegia and uncycloplegia.

对56例行屈光不正矫正术的患者（106只眼）分别用电脑验光（睫状肌麻痹和非睫状肌麻痹下）、显然验光、Zywave波前像差仪法测量眼屈光不正，并将患者按屈光不正度数分为三组：低度近视组(-0.50~-3.00 D)，中度近视组(-3.25~-6.00 D)，高度近视组(-6.25 D~)。

On the basis of the gas chromatographic analysis of n-alkane fingerprint, the method achieved good reliability with selecting seme characteristic alkanes (i.e.n-C17, n-C18, n-C20, pristane and phytane) as the criteria of identifying. The whole procedure was simple and facile while expending short time.

该鉴别方法基于样品的正构烷烃气相色谱指纹分析，选择既能表征油种固有特性，又受风化影响较小的正十七烷n-C_(17、正十八烷n-C_(18、姥鲛烷、植烷和正二十烷n-C_(20等特征烷烃作为判据，可信度大，而且整个操作流程短，较简便易行。

By studying the spectrum properties of coefficient matrix and the regular parameters at the iterative procedure of the first class regular method , we assign a uniform parameter for the inner iteration . Simulation results show that this method for choosing regular parameter is correct and the outer iterate convergence for high contrast object.

这两种方法的正则化效果取决于迭代的次数，我们通过对静态正则化方法中逆散射方程系数矩阵的谱特性、正则化参数等进行分析，对这类迭代正则化方法选取了统一的正则化参数，使得外部迭代方法收敛。

Finally, as a generalization of the group-graded regular ring, the notion of group-graded weakly regular ring is introduced and we discuss it in a new way. In particular, an equivalent condition for the semigroup rings to be weakly regular(T-weakly regular) is given.

将群分次正则环推广到群分次弱正则环；用新的方法研究了环的弱正则性，并得到半群环的弱正则性和T-弱正则性的一个等价刻画。

Aeruginosa increased with the increased initial P concentration in the media;② Under the constant N concentration, the phosphorus uptake of M. aeruginosa was correlated positively with the initial P concentration;③ Under the constant P concentration, the accumulation of phosphorus by M. aeruginosa was correlated negatively with the initial N concentration, but the trend was not obvious and the effect of initial N concentration on the uptake P quantity became ruleless when the initial N concentration reached a higher level (21 mg/L).

结果显示，①氮磷比不变时，随着起始磷浓度的增加，铜绿微囊藻对正磷酸盐蓄积量也逐渐增加，成明显正相关；②氮浓度不变时，铜绿微囊藻对正磷酸盐的蓄积效果与磷浓度正相关；③而同一磷浓度下，铜绿微囊藻对正磷酸盐的蓄积效果与氮浓度负相关，但氮浓度超过21 mg/L时，氮浓度对于铜绿微囊藻蓄积磷的效果影响变得不规则。

By introducing the concepts of semiideal and regular semiideal with respect to a given subring, the general power rings and regular power rings are constructed and a number of examples of non-regular HX rings and non-regular power rings are cited.

通过引入了关于一个子环的半理想与正则半理想概念，构造出一般幂环与正则幂环，并具体给出了若干非正则HX环与非正则幂环的例子。

Thermogravimetric analysis was extended to the measurements on vapor pressures of three n-alkanes, hexadecane, heptadecane and octadecane, on the basis of the Langmuir equation for zero-order vaporization process. The vapor pressures were calculated by two different methods, a constant-parameter one and a comparative one, from the TGA data. These results are in good agreement with the reference data calculated from the Antoine equation.

根据自由蒸发过程的Langmuir关系，将热重分析用于正十六烷、正十七烷和正十八烷等3个正构烷烃的蒸气压测定，分别采用常数法和比较法计算蒸气压，其结果与文献数据符合较好。
