不纯

The pure spring water in heart is very clear, my dream starts to catch the village land, plants, a few brick base, and radius of a few fields. Can't forget picking Atriplex on the tree, Can't forget the sludge playing around the small pond. Can't forget mother's long call when standing at the entrance of the village ...

心中的泉水很纯很清，梦又开始付诸乡村那片土地，一草一木，几垒青砖，一夜柴扉，方圆田地数里，忘不了上树摘榆钱，忘不了村后小河塘的嬉戏，忘不了母亲站在村口有长的呼唤。。。

Twilight reigns over it. We perceive vast fluctuations in that fog, a dizzy mirage, paraphernalia of war almost unknown to-day, pendant colbacks, floating sabre-taches, cross-belts, cartridge-boxes for grenades, hussar dolmans, red boots with a thousand wrinkles, heavy shakos garlanded with torsades, the almost black infantry of Brunswick mingled with the scarlet infantry of England, the English soldiers with great, white circular pads on the slopes of their shoulders for epaulets, the Hanoverian light-horse with their oblong casques of leather, with brass hands red horse-tails, the Scotch with their bare knees plaids, the great white gaiters of our grenadiers; pictures, not strategic lines--what Salvator Rosa requires, not what is suited to the needs of Gribeauval.

com 。黄昏将近，千军万马在暮霭中往复飘荡，那是一种惊心动魄的奇观，当时的军容今日已经不可复见了，红缨帽，飘荡的佩剑，交叉的革带，榴弹包，轻骑兵的盘绦军服，千褶红靴，缨络累累的羽毛冠，一色朱红，肩上有代替肩章的白色大圆环的英国步兵和几乎纯黑的不伦瑞克步兵交相辉映，还有头戴铜箍、红缨、椭圆形皮帽的汉诺威轻骑兵，露着膝头、披着方格衣服的苏格兰兵，我国羽林军的白色长绑腿，这是一幅幅图画，而不是一行行阵线，为萨尔瓦多·罗扎①所需，不为格里德瓦尔②所需。

When we have a fairly much wealth, we should not moil every day anymore. We should relax to do thing we like, not for making money or supporting life, but for joy, appreciation and interest.

当这样的投资获得了稳定的，不一定丰厚的收入之后，就不要再整天为事业而操劳；放松心情，做自己所喜欢做的事，一不为钱财，二不为生活，但求心境愉快，一切纯为欣赏、兴趣而为。

Missirlis in article [1]. At the same time, a sufficient condition for convergence of the PSD method is given to be compared when the coefficient matrix A of the linear system Ax = b is a symmetric, positively defective matrix. In §3.2, an example is given to state that the range of our sufficient condition is wider than theorem 3.3 of article [1]. On the other hand, following a.n analogous approach of [14] and starting the functional relationshipwe have a perfect analysis for the PSD method to converge and optimum valves for the involved parameters under different conditions.Under the assumptions that A is a consistent ordered matrix with nonvanishing diagonal elements and the eigenvalues of the Jacobi matrix of A are real,we get necessary and sufficient conditions for the PSD method to convergence.The result is equal to theorem 1 of article [9].Under the same condition, we can see the optimal parameter and of corresponding spectral radius of thePSD method in [8]:(2)When A is a consistent ordered matrix with nonvanishing diagonal elements and the eigenvalues of the Jacobi matrix of A are imaginary or zero,we get necessary and sufficient conditions for the PSD method to convergence.In chapter 3, the optimal parameter and of corresponding spectral radius of the PSD method are given by table 3.3. Moreover, under the assumption 0

Missirlis在文献[1]中定理3.3的不准确，同时给出了当线性方程组Ax=b的系数矩阵A为对称正定阵时，PSD迭代法收敛的一个充分条件与之比较，并且在§2.3中用实例说明了对于一部分矩阵而言本文得到的充分条件广于[1]中定理3.3的充分条件；另一方面，按照文献[14]的方法，我们从PSD迭代法的特征值λ与其Jacobi迭代矩阵B的特征值μ的关系式：出发，在不同条件下对PSD迭代法的收敛性和最优参数以及最优谱半径进行了完整的分析：(1)在系数矩阵A为(1，1)相容次序矩阵且对角元全不为零，其Jacobi迭代矩阵B的特征值全为实数的条件下，给出了PSD迭代法收敛的充分必要条件，此结果与[9]中的定理1等价，此时最优参数及最优谱半径由[8]得：(2)第三章表3.3中给出了，当系数矩阵A为(1，1)相容次序矩阵且对角元全不为零，其Jacobi迭代矩阵B的特征值全为纯虚数或零时的PSD迭代法的收敛范围和最优参数，并且我们可以得到当0

This work, concentrated on the asymmetric allylation of aldehydes controlled by different chiral auxiliaries prepared from rotational pure tartaric acid, can be divided into three parts.The first part aims to review the developments of chiral drugs and asymmetric synthesis, from which derived the present research topic backgrounds and works.Synthesis and applications of allylation from aldehydes are the second part of the thesis. By optimizing the reaction conditions, such as solvents, temperature, time and chiral auxiliaries like N,N\'-dibenzyl tartamide, N,N\'-p-dimethylphenyl tartamide, N,N\'-o-dimethylphenyl tartamide, N,N\'-o-dichlorophenyl tartamide, N,N\'-a-dinaphyl tartamide, N,N\'-dicyclohexyl tartamide and N,N\'-diphenyl tartamide, ideal experimenttal conditions are obtained according to HPLC monitoring, as well as the auxiliaries\' recoveries experiments. Starting from benzaldehyde and 3-bromopropaldehyde, N,N\'-dibenzyl tartamide is considered the best auxiliary in this reaction.

本文介绍了醛的不对称烯丙基化反应，以光学纯酒石酸为原料，研究了不同构型手性配体在醛的烯丙基化反应中的立体选择性，全文共分三部分十个章节：第一部分对当前手性药物和手性技术进行了概述，并由此展开了本文的研究背景和任务；第二部分为有机合成部分，对醛的不对称烯丙基化反应进行了深入探讨，以苯甲醛为原料对反应条件进行优化，在优化的反应条件下对制备的七种可回收手性酰胺配体(N-苄基酒石酸二酰胺、N-对甲苯基酒石酸二酰胺、N-邻甲苯基酒石酸二酰胺、N-邻氯苯基酒石酸二酰胺、N-a-萘基酒石酸二酰胺、N-环己基酒石酸二酰胺和N-苯基酒石酸二酰胺)进行筛选，优化配体回收实验条件，最终确定出N-苄基酒石酸二酰胺在苯甲醛的不对称烯丙基化反应中具有较大优越性，结晶回收的手性配体光学纯度保持不变。

Heard of other people s children can sleep the whole three months of sleep, and some milk at night to eat can be 1,2 times, and I only eat the 宝宝 two or three times before the past two weeks, every night is necessary to every one and a half hours to eat one, exclusive breastfeeding, and do not feed him he s not hungry, eat the hands, and then began to cry not, in any case do not feed him he will not allow, much less sleep I tried to pacify him,喂水, or not, one night I have to do to feed his 6,7 times, urine is also very much about my dire strait, and during the day to take care of him, basically what睡不成, I will go on like this collapse, we quickly think of a way to help me, my first time when the mother, lack of experience, I hope you give me the ideas!!!

三个多月宝宝晚上总要奶吃怎么办？急！！！听说别人的宝宝三个月就可以睡整觉了，有的晚上吃1、2次奶就可以了，我的宝宝以前还只吃两三次，最近两个星期，每天晚上每隔一个半小时就要吃一次，纯母乳喂养的，不喂他他就饿的不行，就吃手，再不行就开始哭闹，反正不喂他他就不让，更不睡，我试过安抚他，喂水、还是不行，一宿我要喂他6、7次才行，尿的也非常多，我快要困死了，白天还要照顾他，基本上睡不成什么，再这样下去我会崩溃的，大家快帮我想想办法吧，我第一次当妈妈，没有经验，希望大家多给我出出主意！！！
