Then,the tradition manner of crystallization was evaporating and crystalline,but this paper made the other method . The salt-mixture solution of the disodium hydrogen phosphate and the monometallic odium orthophosphate was put in ethanol.

传统的结晶方法是通过加热蒸发结晶，而本文则采用了一种新的结晶方法，在精调后的正磷酸盐混合溶液中加入乙醇，由于正磷酸盐不溶于乙醇，就会使正磷酸盐溶液达到过饱和，再通过搅拌，析出晶体。

The construction procedures used to establish the theory are based on orthogonal and elementary matrix transformations and can, therefore, be developed to a numerically efficient algorithm.

第一部分，我们想利用状态和微分回馈控制把一个时变周期离散的系统正则化，在这部分我们找到一个可以正则化的充分条件，并利用构造方法证明在这充分条件之下可以构造出状态和微分回馈控制矩阵，使的这周期闭回路系统可以被正则化。

in order to simplify a process of getting parameters of daubechies biorthonormal wavelet, according to the fourier cosine transform of scale equation of daubechies biorthonormal wavelet, an algorithm is proposed when the daubechies biorthonormal wavelet has even symmetry double scale parameters.

摘 要：为简化daubechies双正交小波因数的求解，以紧支集daubechies正交小波中尺度关系的fourier变换余弦形式为基础，提出1种当双尺度因数为偶对称时，推导daubechies双正交小波对偶尺度方程因数的方法，并给出构造数值实例。

Using developed optimal model for Ring-Pull Can size design,the optimal solution of cylindric can size design and the suboptimal solution of frustum of a cone on cylinder as well as CCB-1A can size design are botained.

建立了易拉罐尺寸设计的优化模型，得到了正圆柱形罐尺寸设计的最优解和上部为正圆台下部为正圆柱形罐以及CCB-1A型罐尺寸设计的次优解。

Results Two new characterizations of regular rings are given.(1) If R is a left SF'-ring and R/Z is reduced, then R is strongly regular;(2) R is strongly regular if and only if R is a left SF'-ring whose every idempotent element of R is left semi-center and is LANE-ring.

结果 得到了SF'-环是强正则环的两个充要条件：(1)R是左SF'-环，如果R/Z是约化的，则R是强正则环；(2)R是强正则环当且仅当R是满足幂等元左半中心的左SF'-环，且R是LANE-环。

Results The source of the greatest subjective pressure of the HIV infected mostly came from the problem of economy. In regard to the total scores of social health, coping style and social support, statistical significant differences were found between the infected group and the control group and between the family-member group and the control group. The scores of social resources, social contact and social support of the HIV infected were positively associated with that of the use of social support. The scores of social role's activity and social adaptation of the HIV infected were positively associated with that of positive coping style. The scores of social role's activity, social adaptation, social resources and social contact of the infector's family-members were positively associated with that of family-member's subjective. support.

结果 1HIV感染者及其家属的主观最大压力来源大都是经济问题。2在社会健康各维度、应对方式以及支持总分上，感染组、家属组与对照组之间的差异均有统计学意义。3HIV感染者的支持利用度的得分与社会资源和社会接触的得分、社会支持的得分正相关，积极应对的得分与角色活动、社会适应的得分正相关。4HIV感染者家属的主观支持的得分与角色活动和社会适应的得分、社会资源和社会接触的得分正相关，文化程度与社会支持的得分正相关。

The results show that the key of this algorithm is the solution of the integral operational matrix of orthogonal function.

研究结果表明：基于正交函数逼近法的分布参数系统参数辨识算法的关键在于正交函数正、反向积分运算矩阵的求解。

Lapsang Souchong the "Zheng-shan", and that the real "middle mountain areas," meaning that any of the tea produced in Mount Wuyi, are known as being the mountains, while the tea produced in the vicinity of Mount Wuyi, said outside the mountain.

正山小种之"正山"，及表明是真正的"高山地区所产"之意，凡是武夷山中所产的茶，均称作正山，而武夷山附近所产的茶称外山。

With the new matrix, first the inequality in reference [1] was extended to the case of positive rational number n/m, then by taking the limit, the above case was further extended to the case of positive real number.

利用该矩阵，将文献[1]中的不等式推广到正有理数n/m的情形。然后应用极限将正有理数的情形推广到正实数。

Infants are particularly susceptible to nitrite-induced methaemoglobinaemia because fetal haemoglobin converts to methemoglobin more easily. In addition, infants have a low concentration of the reducing enzyme such that methemoglobin is not converted back to hemoglobin as readily.

婴儿特别容易患上由亚硝酸盐引致的正铁血红蛋白血症，是因为胎儿的血红蛋白较易转变为正铁血红蛋白，而婴儿的还原浓度低，较难把正铁血红蛋白还原为红血球素。
