objective to investigate the effect of radiography and method of operation on the surgical indication as well as the operation treatment of lumbar disc herniation and lumbar canal stenosis.methods the data of 300 cases with lumbar disc herniation and lumbar canal stenosis were reviewed from jan 1999 to dec 2004.all cases were treated by the method of minimal invasive open operation.the nucleus was resected through an 3.5～4.5cm in length.the sacrospinalis muscle between laminae was stripped partly and the part of upper lamina and the part of medial facet was resected.

目的 探讨影像学检查和手术方法对腰椎间盘突出症和椎管狭窄症手术方式和适应证的影响。方法自1999年1月～2004年12月，为300例腰椎间盘突出症和椎管狭窄症患者实施微创开放式手术，做3.5～4.5cm长的皮肤切口，剥离椎间的部分骶棘肌，咬除部分椎板上缘及小关节内侧缘后，摘除髓核，并根据需要做半椎板或全椎板手术或扩大神经根管和切除肥厚的黄韧带及神经管内的骨性增生。

Half the thrill of the excursion is witnessing cultural treasures that few Westerners have seen since Marco Polo: in Kyrgyzstan, Saka petroglyphs that date back to the Bronze Age; in Kazakhstan, the Zenkov Cathedral, a wooden masterpiece built entirely without nails; in Tajikistan, early Persian ruins at Bunjikath; in Uzbekistan, the massive Bibi Khanym mosque, crown jewel of the Silk Road trading city of Samarqand; and in Turkmenistan, the brilliantly woven carpets in As?

旅行中一半的激动来自于成为自马可波罗以来很少西方人能够见到的文化瑰宝的见证人：在吉尔吉斯斯坦，萨卡人的岩石壁画可以追溯到青铜时代；在哈萨克斯坦，Zenkov大教堂，一个完全木制没有一根钉子的杰作；在塔吉克斯坦，Bunjikath有古波斯的遗址；在乌兹别克斯坦，Bibi Khanym清真寺宏伟壮观，还有丝绸之路上的贸易城市Samarqand的王冠珠宝；还有在土库曼斯坦，As？

The result shows that for both PCL homopolymers and PCL-b-PEG block copolymers, the spherulitic linear growth rate first increases with molecular weight and reaches a maximum, then decreases as molecular weight increases. Crystallization temperature has greater influence on the spherulitic growth rate of polymers with higher molecular weight.

当自由PEG在水中的占有面积S_o与单根PEG链段所占有的表面积S的比值S_o／S的值接近或小于3时，PEG链段对胶束形状的影响较小，PCL嵌段的影响占主导地位，易形成片状胶束；当S_o／S的值在3-10之间时，随着PCL嵌段分子量的增加，PCL-b-PEG嵌段共聚物在水溶液中自组装形成类似球状、棒状和蠕虫状胶束，是PEG与PCL嵌段共同的作用的结果；当S_o／S的值大于10时，易形成球状胶束。

We set up the angular momentum conservation model of wind accretion of Ba stars, and then derive the change equations of the orbital elements. Finally, combining the heavy element nucleosynthesis of AGB stars, we creatively calculate the heavy-element overabundances of barium stars in a self-consistent manner adopting accreting and mixing on successive occasions.

我们建立了Ba星形成的星风吸积的角动量守恒模型，推导出其轨道根数的变化方程，并结合AGB星的重元素核合成，通过逐次脉冲吸积与混合，自洽地计算出Ba星的重元素超丰。

Seeing himself as a messenger of the future, he ceased concertizing in the late 1840s to devote himself to composition and furthering the work of progressive composers. In the 1850s he wrote many of his most ambitious works, including A Faust Symphony (1854) and the piano sonata in B minor (1853). In 1865, abandoning hope that Princess Caroline de Sayn-Wittgenstein would marry him, he took minor church orders.

李斯特自视为未来的使者，在1840年代晚期停止了音乐演奏而专心作曲，并进一步影响了革新派作曲家的作品。1850年代，他写了许多最具野心的作品，包括《浮士德交响曲》（1854）和《B小调钢琴奏鸣曲》（1852-1853）。1865年他放弃了与赛因－维根斯坦公主成婚的希望，接受教会次级的神职职位。

Even if I am around the haughty air and piously has spread into many of the old structures Lane termites can be filled with cheese and bacon, fresh sweet-breathing, but have warming, I think the long frozen hearts.

就算我周围的冷言冷语和虚情假意已经多到泛滥成老木屋里的白蚁，可充满芝士甜香和培根鲜位的呼吸，反倒温暖着，我自以为早就冷冻的心。

The B3LYP/6-31+G level of theory and the polarizable continuum model are employed to study the binding interactions between amidinium and tetrazolate anion which have two binding modes (side-on and end-on) as well as the binding interaction between amidinium and formate anion. We find, in the gas phase, that the end-on acetamidinium tetrazolate is more stable with its interaction energy 3.56 kJ/mol higher than that of the side-on.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
