In the tune "the old city" represents Beijing, the music take the Peking opera as the source material, will divide the slow movement and the musical beat two parts, the slow movement sub-system will be persuasive the exquisite Peking opera melody to further process, causes it music, has displayed the urheen timbre delightful gentle performance special skill, will listen both to express feelings, the Beijing style to be full exquisitely, and will not lose the sonorous powerful place, music mood fluctuation repeat swings, the change will be careful, musical beat partial melodies sprightly smooth, by the urheen continuously the fast figure and the clear bright timbre, will entrust with this section of musics fresh and the active characteristic, but long will draw out a syllable appearance, also will then cause it alone lyricism, this music from differentThe angle expresses thinks of the ancient exquisite feeling, takes to the people infinite province to think with recalls.

曲中&古城&意指北京城，乐曲以京剧为素材，分慢板与流水板两部分，慢板部分系将婉转优美的京剧唱腔进一步加工，使之更加音乐化，发挥了二胡音色甜美柔和的演奏特长，听来既抒情优美、京味十足，又不失铿锵有力之处，音乐情绪起伏迭荡，变化细致，流水板部分旋律明快流畅，以二胡的连续快速音型和清脆明亮的音色，赋予本段音乐清新而活跃的特色，而长拖腔的出现，则又使之独具抒情性，本乐曲从不同角度抒发思古幽情，带给人们无限的省思与回忆。

Moreover, its microstructural characters possess several configurations under TEM, which are (1) ferrite laths with obvious interface,(2) ferrite laths without obvious interface, but the interface can be discerned faintly from the linear arrangment of those directional islands,(3) the coexistence of ferrite laths and non--equiaxed grains. These are somewhat different from those of weld structures, which are generally thought to consist of an assemblage of interwoven ferrite laths.

管线用针状铁素体钢热轧板材中有明显界面的板条束或针状片条束；没有明显界面的板条束或针状片条束，可根据条状物或岛状物的有方向性的线状分布依稀辨别界面的存在；板条或针状片条与非等轴晶共存等多种不同形态，并不象焊接组织那样通常是单一的针状片条束或板条束形态。

The repulsion is to be expected when the two parallel slabs have different electromagnetic properties. By studying different cases containing ordinary materials and metamaterials, we found that the repulsive behavior may possibly appear when the wave impedances, which are used to demonstrate the difference of electric and magnetic properties between two slabs, are smaller and larger than the impedance of vacuum, respectively, and moreover, the greater the difference between two wave impedances, the more easily the repulsive force is obtained.

排斥的Casimir作用力只可能出现在两不同平板的情况中，而通过考察正常材料与特异材料介质的不塑料托盘同组合情况，我们发现板间媒质阻抗的值介于两板的阻抗之间且两板阻抗比与板间媒质的差异越大，Casimir排斥力越容易产生。

The stress and strain of jaw crusher teeth plate have been simulated and studied with finite element analysis by means of determinate mechanics.

应用确定性力学方法，对齿板应力和应变进行了有限元仿真研究，通过对仿真结果的分析，认为基于确定性力学的齿板应力和应变仿真只能部分反映其真实受力状态，齿板类零件在有限元仿真中的载荷施加方法应进一步研究，以真实地反映齿板在实际工况下的受力情况。

Through research and analysis of data, it was observed that the length and width of bark fiber varied according to the lop and age, the results show the fiber of the Salix bark is longer than the Salix and width of fiber almost same, fiber length of the Salix bark mainly influenced by the times of lop. The ash in Salix bark,1% Sodium Hydroxide Solubility in Salix bark, water solubility in Salix bark, Ethanol-Toluene in Salix bark, acid-insoluble lignin in Salix bark changed with the lop and age is also been investigated, the component of Salix bark is higher than Salix except acid-insoluble lignin,and it's high effected by times of lop; the TG analysis and DSC analysis is been used on the Salix bark and Salix to study the character of the hot-action, and the rang of the pyrogenate temperature is confirm; the quantity of Salix bark effect on the MOR, MOE, swelling in 24h water, nail withdraw and inner strength was determined, the results show that the Salix bark notability effect on the properties of board and dropped it; the properties of the Salix bark board is nearly the board product by other bark residues, it was established the multi regression equation of each properties and optimized the fitting produce condition of Salix bark board.

通过试验和数据处理，得出了沙柳树皮纤维长度、宽度随平茬和材龄的变化规律，结果表明沙柳树皮长度要比沙柳材的要长，宽度基本相同，沙柳树皮纤维长度主要受平茬次数的影响；找出了沙柳树皮中灰分、冷热水抽出物为、1%NaOH抽出物为，甲苯乙醇抽出物、酸不溶木素与平茬次数和材龄之间的关系，除酸不溶木素外，其他成分均明显高于沙柳材，沙柳树皮的化学成分主要受平茬次数的影响；利用TG和DSC法分析了沙柳树皮和沙柳材的反应热特征，确定了热解的温度范围；研究了沙柳树皮量对于刨花板MOR、MOE、吸水厚度膨胀率、握钉力以及内结合强度的影响，结果证明沙柳树皮量对于刨花板的各项性能指标影响显著，它的掺入降低了刨花板的各项性能；对沙柳树皮板的研究表明，沙柳树皮板的各项性能与同类树皮板的性能基本相近，建立的二次回归模型稳定，并利用回归方程求出了适宜的沙柳树皮板制造工艺。

In addition, three-dimensional flow analysis is carried out to verify the performance improvement of the new support board. It is found that with the new support board the efficiency of the fan is improved over the entire range of mass flow, the losses are reduced and the flow in support board passage become more reasonable.
