Even weassume that such an invariant measure exists,there are still problems related to the nonex-istence of the corresponding functional integral when we apply this technique to concreteproblems,such as constructing gauge invariant operatorsout of gauge variantones.

即使我们假设这样一个不变测度存在,当我们将这一技术应用到具体问题时,比如由规范非不变的算符构造规范不变的算符,仍然存在由于相应的泛函积分不存在而带来的问题。

In the present work,the existence and uniqueness results aboutperiodic boundary value problems for different kinds of the nonlin-ear periodically perturbed nonconservative systems are establishedthrough the discretization technique,under suitable assumptions,by using global inverse function theorem and result about the ex-istence and uniqueness of periodic solution for nonhomogeneouslyfirst order linear periodic boundary value problem.

本文的第一章概述了在讨论原问题解的存在唯一性过程中以及构造和分析相关的数值求解方法时将要用到的全局反函数定理、有关矩阵特征值的若干重要引理、线性常微分方程非齐次周期问题解的存在唯一性定理和单参数影射方法及有关结论,并简单回顾了已有的证明非线性微分方程周期边值问题解的存在唯一性的方法,其中包括谱理论、最大最小化形式方法、摄动技术和全局反函数理论方法,最后,介绍了两类数值求解非线性微分方程问题的方法。

Three counter-examples of topological space are proposed in this study: There are two metric spaces, X and Y, in which and are isometric, whileand are not isometric; Non-metric tight regular space is a counter-example of the separation of topological space; No non-zero continuous linear functionals of the linear topological space is a counter-example of linear topological space.

这里给出三个反例,存在两个度量空间X与Y,使X^2与Y^2等距而X与Y并不等距是拓扑空间中的反例;存在不可度量化的紧的完全正规空间是拓扑空间分离性的反例;不存在非零连续线性泛函的线性拓扑空间是线性拓扑空间的反例。

1:250000 geological mapping has further revealed the mysteries of the tectonics of the Qinghai-Tibet Plateau. The Altun Mountains are not of the Tarim massif, but a part of the Kunlun-Qilian-Qinling orogenic system; the Altun fault is a large transform fault; the Muztag-Maqên suture zone and Jinshajiang suture zone are both Variscan ones; the Songpan-Garzê area in the Triassic was a huge turbidite basin on the southern margin of Laurasia; the Gangdise belt underwent the important Indosinian orogenic movement; an ocean basin that persisted from the Paleozoic to Triassic did not exist, i.e. the so-called Paleo-Tethys or permanent Tethys was not in existence in the Qinghai-Tibet Plateau. In the Paleozoic, most parts of China, including the Sino-Korean, Yangtze and Tarim massifs and the Qinghai-Tibet Plateau, were located in south of the main ocean basin—the Central Asian-Mongolian sea way—of the Paleo-Asia ocean, belonging to the northern margin of Gondwana. The Yarlung Zangbo and Bangong -Nujiang belts were twins in the Tethyan Ocean, which began to develop into two ocean rift belts in the Triassic. The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be subducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian, Yanshanian and Himalayan stages.

1:25万地质填图进一步揭开了青藏高原地区大地构造的奥秘:阿尔金山是昆仑,祁连-秦岭造山系的一部分;阿尔金断裂确是一条大型转换断层;木孜塔格-玛沁缝合带和金沙江缝合带均是华力西缝合带;松潘甘孜三叠系沉积盆地是劳亚大陆南部边缘的浊积岩盆地;冈底斯带曾经历了重要的印支造山运动;不存在从古生代延续到三叠纪的大洋盆地,即不存在所谓古特提斯或永久特提斯;古生代时期,在青藏高原地区亦不存在具古生物,古地理分隔意义的大洋盆地,当时,包括中朝,扬子,塔里木以及青藏高原地区在内的中国大部分均位于古亚洲洋主洋盆——中亚-蒙古带之南,属冈瓦纳大陆结构复杂的北部边缘;雅鲁藏布江和班公湖-怒江带是特提斯洋中的孪生姊妹,它们均是从三叠纪起就发展成大洋裂谷带的;以雅鲁藏布江带为主洋盆带的特提斯洋,从三叠纪晚期开始消减,经历了印支,燕山,喜马拉雅3个阶段脉动式板块汇聚造山过程。

The results showed that there were two kinds of grains in the cells,one was large and had low electron density,Gl for short,while the other was small and had high electron density,Gh for short.The latter ones had a circle around it which can be seen through the microscope.During the aroma releasing period,the shape of the two grains changed distinctly,which led to the inference that Gl was the leucoplast,the store-room of aroma precursors or energe substances,and that the Gh was probably the lysosome which is related to the enzyme system?s aroma producing.The circle around Gh is the formed fragrant constituents and the aroma forming is the result of the interaction of Gh and Gl .

结果发现,茉莉花瓣细胞中存在电子密度较低、体积较大的颗粒和电子密度较高、体积较小的颗粒(分别简称为Gl和Gh颗粒),并在Gh颗粒周围存在清晰的晕圈;在茉莉花释香过程中,两种颗粒在形态上均发生明显的变化,推测Gl颗粒可能是白色体,是茉莉花香气前体物或能量物质的贮存器,Gh颗粒可能为溶酶体,与香气形成的酶系统有关,Gh颗粒周围存在的晕圈可能是香气物质,香气物质的形成是Gl和Gh颗粒相互作用的结果。

All was unexpected. Likin, though, was temporary tax that the Qing Dynasty established for raising money to repress the taiping rebellion. It had been censured for seventy eight years. This showed that the existence of likin had its profound background of economy and society. Abolishing likin was to "change a little, then influence the whole", and it existed contradiction not only between China and other countries, but also between the center and the local authority. The problem of likin systems abolition was the problem about not only economy but also politics.

厘金虽然一开始是清王朝为筹措镇压太平天国运动军费而设立的临时税种,但其屡遭非议却长达78年的历史表明,厘金的存在有其深刻的经济与社会背景,"裁厘"可谓是"牵一发而动全身",不仅存在着中国与各国列强之间的矛盾,而且存在着中央与地方政权之间的矛盾,厘金的裁撤问题,既是经济问题,又是政治问题。

The result shows that:① Annual scale of China's inbound and domestic tourism growth process can be divided into 3 parts: trend, cycle, and impacts of the incidents.② The trend and cycles of inbound tourism are different from the domestic. Inbound tourism grows lineally while domestic grows exponentially.③ Inbound tourism experienced two different kinds of cycles.

结果发现:(1)近20多年来我国入境和国内旅游的成长,在年际尺度上均可分解为趋势项、周期项和事件冲击项3个部分;(2)入境旅游和国内旅游客流量的增长趋势存在一定的差异,入境旅游长期趋势为直线增长,国内旅游长期趋势为指数增长;(3)入境旅游存在2个时间尺度的客流量波动周期,较长的周期为20年,较短的周期为6年,而国内旅游只存在一个10年左右的周期。

They mainly come from the plants containing in generating-coal environment, and meantime are affected by water media, groundwater activity, hot liquefacient magma and the surrounding rock etc.

微量元素在煤中均可以有无机态和有机态等形式存在,只是结合的能力和稳定性不同,F、Cl主要以有机态存在,其它金属元素以无机态存在为主。

Neither is there only a habit of goodness, directed by right reason; but there is in some men, even in nature, a disposition towards it; as on the other side, there is a natural malignity.
