非定态

After achieving the solution of the mathematical model,a binomial productivity equation of gas-water well with two-phase flow in formation was derived in consideration of the influence of formation damage and non-Darcy effect,thus establishing the theory of transient inflow performance relationship curve of gas-water well.

文章基于质量守恒原理，建立了气水两相地层瞬态渗流的数学模型，通过定义气水两相拟压力函数，将渗流数学模型线性化，在获得数学模型解后，考虑地层损害和非达西效应的影响，推导出在地层中为水气两相渗流的气水同产井的二项式产能方程，从而建立了气水同产井瞬态流入动态关系曲线的理论。

Among the myriad examples of Sichuan's intangible cultural heritage, if the folk songs, ditties, stringed musical instruments, tea ceremony and drum performance etc represent the elegant and unworldly spiritual pursuit, then the pottery figurine featuring the ancient story-teller of the Eastern Han Dynasty excavated in Chengdu as well as the local traditional artistic performances that are to be presented before you such as the golden-coin-clapper talking, Qingyin and Sichuan-style rod puppet show will enable you to have a more intimate understanding of the distinctive cultural personality of Sichuan people, that is, their most conspicuous trait that is carried by their embedded qualities of fortitude, bravery, detachment and composure: their philosophical sense of humor.

如果说，山歌，小调，琴瑟，茶艺、鼓乐……，这些非物质文化活态遗存点染着四川人典雅、高洁的精神追求，那么，从四川成都出土&击鼓说书，喜形于色&的东汉陶制说书俑到你将要欣赏到的四川金钱板、清音、杖头木偶、川剧这些传统艺术表演中，你会真切感受到四川人特立独行的文化人格，那就是浸润在骨髓里坚毅、勇敢、淡定沉着的精神内涵承载起的性格特征——幽默、达观。

The introduction of quark delocalization can be viewed as taking into account either the contribution of excited configurations or the distortion of individual baryon due to mutual interaction, its characteristic is to allow the six-quark system to choose the favorable configuration by its own dynamics automatically; Various quark models extended linear or quadratic confinement potential for 3q system to 6q system directly. Due to the nonlinearity of QCD, quark-quark interaction in color singlet may be different from that in non-color singlet. For example, the contribution of three-gluon exchange to one baryon is different from that to two baryon singlets, and so on.

引入夸克蜕定域效应，既可以看作是考虑了具有较高能量的激发组态的贡献，也可以看作是考虑了重子不碰撞过程中发生了畸变，其特点是让夸克体系自动选取最有利的组态；以往的QCD模型总是将哈密顿量直接从单重子系统推广到双重子系统，但QCD理论是一个非线性理论，处于色单态的两个夸克间的相互作用可能不同于处于非色单态的两夸克间的相互作用。

Nonlinear partial differential dynamic equations of bending vibration of a tilting stepped drive shaft with two supports were built under non-inertia movement coordinate system by theorem of the motion of mass center and Heaviside function. According to the condition of equal displacement in an adjoining plane of the shaft, an equivalent shaft and its equation were obtained. A motion equation of the equivalent shaft was obtained by method of Galerkin. An approximate steady-state solution of the main resonance was obtained by method of multiple scales. The influence factors, motion stability, amplitude jump of main resonance of a stepped drive shaft and so on were analyzed.
