Besides, The reaction of aldehydes with dithioacetate enethiolates followed by alkylation effectively gives α-hydroxyl ketene dithioacetals.

此外，用醛与硫代羧酸硫酯反应再通过烷基化也可以有效地获得α-羟基二硫缩烯酮类化合物。

In chapter four molecular modeling method is employed to comparatively study five S-allyl γ-hydroxy ketene dithioacetals reactions of Thio-Claisen rearrangement with and without zeolite catalysts.

An efficient iterative lagrange multiplier approach is proposed for the design two-channel low delay perfect reconstruction filter banks.

摘要本文提出了一种用有效的迭代拉格朗日乘子法设计精确重构的两通道低延迟滤波器组。

The theoretical analysis and experimental results show that the result of the first one has bug error with optimal results, and the second one is superior to the former, and the third one is best, which can get the optimal result based on least upper bound of error probability.

证实了"基于最小错误概率上界特征提取"是目前可以用迭代算法完成的最好的特征提取，而"基于马氏距离特征提取"在错误概率上界上升很小的代价下，简化了计算量，也是一种可行的方法。

Those hours, that with gentle work did frame The lovely gaze where every eye doth dwell, Will play the tyrants to the very same And that unfair which fairly doth excel: For never-resting time leads summer on To hideous winter and confounds him there; Sap cheque'd with frost and lusty leaves quite gone, Beauty o'ersnow'd and bareness every where: Then, were not summer's distillation left, A liquid prisoner pent in walls of glass, Beauty's effect with beauty were bereft, Nor it nor no remembrance what it was: But flowers distill'd though they with winter meet, Leese but their show; their substance still lives sweet.

五 那些时辰曾经用轻盈的细工织就这众目共注的可爱明眸，终有天对它摆出魔王的面孔，把绝代佳丽剁成龙锺的老丑：因为不舍昼夜的时光把盛夏带到狰狞的冬天去把它结果；生机被严霜窒息，绿叶又全下，白雪掩埋了美，满目是赤裸裸：那时候如果夏天尚未经提炼，让它凝成香露锁在玻璃瓶里，美和美的流泽将一起被截断，美，和美的记忆都无人再提起：但提炼过的花，纵和冬天抗衡，只失掉颜色，却永远吐着清芬。

We can communicate with English in the future if there is nobody konws Chinese there.i am glad that you said you coukd read my letter ,but these lett...

如果你那里没有会中文的朋友，那么以后我们还是用英文通信吧，谢谢你说能读懂我的信，不过这些信都是我让别人代写的，我自己写起信来还是有些吃力。

Twenty-six eyes which appeared rejection after allograft penetrating keratoplasty between April 2003 and April 2004 in Shandong Shi'erming Eye Hospital were collected, including 16 males and 10 females, 9 cases were repeated relapsing viral keratitis, 8 cases were traumatic posterior corneal leucoma, 5 cases were corneal decompensation caused by various intraocular surgery, 2 cases were congenital leucoma, and 2 cases had other symptom. The rejection occurred at 2 month to 2.5 years after operation. Among them 19 cases were transferred to our hospital and asked adding traditional Chinese therapy because western medicine was ineffective in other hospital.
