For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time. And that will cause the error oversize gradually; and also have another part error are unconventional , unforeseen.

对各类冲模冲件误差在冲模整个寿命中出现的波动、增减趋向及规律等进行全面分析便可发现：冲件误差的主导部分是不变的；因刃口或型腔的自然磨损而出现的误差增量随冲模刃磨冲数增加而使这部分误差逐渐加大；还有部分误差的增量是非常规的、不可预见的。

Based on the structural model of tracheid from Bolton and Petty,the flow-resistor of tracheidis assumed to consist of four components in series.

设若一个管胞的流阻为Rg，管胞腔的流阻为RL，纹孔系统3部分的流阻分别为RPA、RBT和RMo；又，在某一个纹理方向上管胞纹孔的数目是N，纹孔膜的微孔数目是NM，则管胞在该纹理方向上流阻的数学表达式为

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。

When the flow rate through the Poppet head reaches a certain size, balance piston upper and lower chamber of the two oil pressure difference will create upward hydraulic pressure exceeds the spring preload and balanced piston friction and balance the sum of the piston weight and other forces, balance piston upward, so that the pressure port and overflow port interlinked, a large number of pressure from the oil will flow back into the fuel tank from the overflow port.

当通过提动头的流量达到一定大小时，平衡活塞上、下两腔的油压力差将形成向上的液压力超过弹簧的预紧力和平衡活塞的摩擦阻力及平衡活塞自重等力的总和，平衡活塞上移，使压力口和溢流口相通，大量压力油便由溢流口流回油箱。

At the same time, the resonant frequencies of four kinds of resonator are calculated by the programs which are made with Matlab software. The effect of resonator geometrical parameters on resonant frequency is theoretically analyzed. In order to carry out the acoustic and aerodynamics performances tests, seven resonators are designed and made, and a specialized engine intake silencer and exhaust silencers test bench was designed. The tests and analysis are performed as well.

在此基础上设计并加工了两类七个共振型进气消声器，研制了发动机进排气消声器性能测试实验台，开发了发动机进排气消声器声学性能测试软件，并在该实验台上测试了所设计的进气消声器静态工况下的传声损失，从实验的角度研究了共振腔的尺寸、形状对其共振频率的影响及其趋势。

Not only the permeability of the rock salt body, the convergence of the cavity and the stability of jambs must be considered , but also the heterogeneity of the interlayers must be full considered, like the permeability of interlayers and layers , the difference of interlayers .

不仅要考虑岩盐矿体的渗透性、溶腔的蠕变收敛性、矿柱的稳定性外，还要充分考虑夹层的不均质性，如夹层及层理的渗透性，夹层和盐层蠕变的差异性。层状岩盐矿床中建造油气储库是一个相当复杂而且涉及很多学科的深部岩土工程。

Here make further analysis and comparison with the traditional processing welding spark mosaic surface electric sparking, CAD/CAM intergneated techniques used in the fabrication of two halt mold and introduced techniques of chrominum plating, sand blast and spraying dry ice for surface treating the developing trend of tire mold prospected.

对传统轮胎两半钢质模的加工工艺和焊花、镶花轮胎模具的加工工艺，电火花加工轮胎模具技术，CAD/CAM集成技术在模具加工的应用作了剖析和比较。轮胎模具型腔的镀硬铬、喷砂和喷干冰表面处理技术也一并作了介绍。探讨和展望了轮胎模具设计制造的发展趋势。

The external diameter of a quartz liner is determined to be 36-46mm, the inner diameter to be 32-40mm and the length of the liner to be 1.45-1.85m for the process of PCVD. Parameters of a processing technology are that the high frequency power of a microwave resonator is controlled to be 6KW-15KW and the deposition temperature is 1080-1130 degree Celsius. The variety of mixed air flowing through the liner includes silicon tetrachloride vapor, germanium tetrachloride vapor, high-purity oxygen and Freon. The inside pressure of the liner is 10-15millibar. The air flow rate inside the liner is
