The "product line---demand---consumers" pyramid" model combining with Maslow"s Need Hierarchy Theory explains the dynamic relationship among the luxury brand"s core products, the main targeted consumers and their main demand. Firstly, competition, sales pressure, market development and other reasons make the core products and product lines growing, namely downward to the bottom of the pyramid; Secondly, with the product line downward to the bottom of the pyramid, the number of luxury consumers has been expanded; Thirdly, because of the exclusive consuming demand, consumers" requirements of conspicuousness and self-fulfillment for the luxury goods are upward to the top of the pyramid.

因此，本研究结合马斯洛需求层次理论，提出了"产品线—需求—消费者金字塔"模型，说明了奢侈品品牌的核心产品、主要目标消费者及其主要需求之间的动态关系：第一，由于竞争、销售压力和市场发展等方面的原因，使得核心产品、产品线有扩大的趋势，即向金字塔下方发展；第二，随着产品线向金字塔下方发展，奢侈品的消费者数量也随之扩大；第三，由于消费需求的排他性，消费者对奢侈品的炫耀性和自我实现性要求则是向金字塔上方发展的。

2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.

深入剖析：地球可以说是一个非常奇妙的热核反应堆，当地球内部的压力达到一定的临界，地球物质中可衰变的核物质统称为热核物质，就会发生热核反应，从而产生巨大的能量，进而融化部分物质，形成岩浆即液态物质，这个反应层面可能是多个层面，第一层可能位于地壳与地幔之间，向上下两边对流，表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象；第二层可能位于下地幔与地核之间，压力更为强大，引起不易发生热核反应的热核物质发生反应，形成相对比较稳定的液化物质层，同时向上下两边对流，形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象；这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。

The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。
