Based on concept of U(1)-invariant adiabatic expansion we propose an invariant perturbation theory of quantum adiabatic process, furthermore, we obtain a new adiabatic condition.

我们提出了绝热轨道、绝热演化轨道及U(1)不变的绝热轨道和绝热演化轨道等概念，重申了绝热演化的含义。并在U(1)变换不变展开的基础上给出了绝热近似不变微扰理论新的绝热条件，并进一步得到了新的绝热条件。

The paper is made up of two parts:Firstly, we studied systematically the radiative decays of light vector mesons:〓in the framework of a U(3)L×U(3)〓chiral theory of mesons. In this theory, low-lying pseudo scalar, vector, axial vectormesons are introduced as the bound states of the quark fields.

全文分轻味矢量介子辐射衰变和重味矢量介子的软π衰变两部分：首先，我们在U(3)〓×U(3)〓手征介子理论的框架内，系统的研究了轻味矢量介子ρ，φ的辐射衰变〓在该理论中，低能的赝标，矢量和轴矢介子场是作为夸克场的束缚态被纳入。

Ferrari began in Brazil with Cruzeiro, but made himself known in the U.S. with Saint Benedict High School (in New Jersey, and considered as the school with the best soccer program in the country), and with the U-16 Metro Stars (ex-team of Italy coach Donadoni, now called the Red Bulls), in which he won the 2005 national championship in his age group, also gathering the title of Player of the Year.

费拉里是在巴西克鲁塞罗开始踢球的，但他是成名于美国的圣本尼迪克特中学(在新泽西的这所中学被认为是全国足球计划最好的学校)，并且拥有16以下地铁星队(意大利教练多纳多尼的前队，现在叫红牛)，他的球队赢得2005年度U-16年龄段全国冠军，他也获得了该年龄段年度最佳球员的头衔。

Drawing on the resource-based view of firm,this paper suggests that an inverted-U shaped relationship exists between market orientation and radical innovations,and offers a theoretic model that focuses on the curvilinearity of the moderating effect of market orientation on the entrepreneurial orientation-radical innovations ...

基于资源与能力理论，在企业家导向对突变创新正向影响的基本命题基础上，分析了不同水平市场导向对企业突变创新的倒U形影响关系，以及市场导向对企业家导向和突变创新间正向关系的倒U形调节作用。

U are the sea,i am the shell.no matter how far away u are ,just press the trumpet shell close to your ears,u can hear my heart calling...

This thesis presents the studies of U-shape gantry structure of container gantry crane, and dynamic simulation and fatigue life estimation of its rigid anti-sway. The main contends are as follows: Supposed that trolley frame is composed of spring structure, due to larger trolley gauge of U-shape gantry structure. For the gantry crane, a series spring dynamic vibrating model with three masses, three freedoms of degrees is built in this thesis and vibrating calculus equations are precisely resolved by mode analyses rule.

本文研究集装箱门式起重机U型门架结构及其刚性减摇系统的动态仿真和疲劳寿命估算，主要内容如下：由于U型门架结构小车轨距较大，本文建立了考虑小车架为弹性结构时门式起重机的三质量三自由度串联弹性动力学振动模型，用模态分析法求解振动系统微分方程组的数值精确解。
