This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

The paper says, in order to deal with the challenges of knowledge economy and economy globalization, as well as to re-set up public confidence in accounting profession, we need to step up accounting management reform and innovation as follows on one hand: use international experience for reference to accelerate the process of accounting internationalization, and reduce chances of providing false account; carry out outside and inside supervision at the same time, that is, improve corporate governance and internal control system, deal with "insider control problem" from inside of the system, and fundamentally resolve the problem of corporate accounting falsification; intensify government supervision and profession self-discipline from the outside, and strengthen punishment; set up civil litigation and civil compensation system, especially to run corporation deputy's liability so as to make false account provider get more kicks than halfpence, and restrain or eliminate falsifying impulse.
分析认为,为迎接知识经济与经济全球化的挑战,重树社会公众对会计业的信心,我国一方面急需加快会计管理的改革:借鉴国际经验,加快会计国际化进程,压缩会计造假的空间;实行内外监管并举,即在内完善司治理结构、建立健全内部控制制度,从系统内部解决"内部人控制问题",以从根源上治理财务造假等问题,在外加强政府监管与行业自律并举,加大惩处力度,建立民事诉讼和民事赔偿制度,尤其是加大对公司法人代表的责任追究力度,以使蓄意提供虚假会计信息变得得不偿失,从而抑制或消除其造假的冲动。

First, in this essay, the author states the reasonableness and necessity of permitting transfer of mortgaged property, affirms that mortgager will not lose the right of dispose and is entitle to transfer the property freely when the property is under mortgage. And at the same time, the author agrees the theoretical basis of droit de suite and the mortgagee's interests can be protected through the enforcement of the recovery right. Second, the author introduces the legislation of droit de suite in several countries with typical civil law legal system and analyses the particular characteristics of these different registrations. Third, the author points out the defects and malpractice of the legislations in our country after analyzing the legislation which state ambiguously the recovery right of mortgage and restricts the transfer of mortgaged property based on the tracing the development of system in respect of transfer of mortgaged property in Chinese legislation on guarantee. Finally, according to the real situation of our country, the author presents some concrete proposals on perfecting the system of transfer of mortgaged property and droit de suite of mortgage to reach the balance between static safety of property rights and dynamical safety of transactions with the reference to successful expericnees of other countries.
本文首先从理论依据出发,论述允许抵押物转让的合理性与必要性,肯定抵押人在抵押期间不丧失对抵押物的处分权,可以自由转让抵押物,同时认为抵押权追及力的存在具有理论基础,通过赋予抵押权以追及效力即可保障抵押物转让关系中抵押权人的利益;其次,简要介绍几个具有典型意义的大陆法系国家关于抵押权追及力的立法状况,分析各国立法的侧重点;再次,结合我国担保立法关于抵押物转让制度的发展轨迹,对我国立法未明确承认抵押权所固有的追及效力,且限制抵押物转让的规定进行剖析,认为存在一定的疏漏和弊端,具有明显的不合理性;最后,根据我国国情,并借鉴国外立法的成功经验,提出完善我国抵押物转让及抵押权追及制度的具体立法建议,以寻求物权的静态安全与交易活动的动态安全的平衡。

Multiple wavelengths characteristics of dayside aurora activities were investigated with these keograms and in reference to all-sky images. It was found that there are three repeatedly appearing aurora activity regions along the dayside aurora oval. They are, Region A around 0900MLT in which aurora moves poleward while its intensity decreasing, and its form changingfrom arc to corona with time; Region B around 1330MLT in which aurora moves equatorward while its intensity increasing, and its form changing from corona to arc in time; Region C around 1330MLT in which aurora expands poleward while its intensity decreasing, and its forma evolving from arc to multiple arcs in time. There is a narrow belt of aurora activity in North-South direction between Regions A and B, which is dominated by weak and red corona aurora.

Firstly, we used the Raman scattering method which can calibrate in real time to measure the O2 (a1 Δ) yield of SOG for the first time in China. The measurement relative error is less than 8%. Based on the data from the experiments, we report the results that the diluent category and ratios influence the O2 (a1 Δ) yield. The relationship of P-τ values and the O2 (a1 Δ) yield of this SOG were given. The effects of distance and bypass of gas transportation on the O2 (a1 Δ) yield are investigated. Secondly, the chlorine utilization was measured by using Raman spectroscopy simultaneously when the O2 (a1 Δ) yield was measured. This method originated with us. The result about the chlorine utilization is coincident with other theoretic and experimental conclusions. The relationship given in this paper between gas stay time in SOG and chlorine utilization offers reference to improve the reaction efficiency and chemical efficiency of COIL. Finally, the partial water vapor pressure at the exit of SOG was measured by absorption spectroscopy. The water vapor fraction and partial pressure have trends changed with the generator total pressure, the diluentratios, and the BHP temperature. These experimental results are very important to improve experimental conditions of SOG, reduce the water vapor fraction, and enhance the output power of COIL.

With the translation of Buddhist scriptures into Japan's gradual understanding of the "China" and began referring to the use of such air and sea in its master of poetry,"Ling-set","China is Taiwan's Yue Man sequence" of the sentence, of course, at that time "Shina language with a copy of the translators Buddhist usage, but is not common reason for this is has always been to China, said the Japanese usually morokoshi, tohn, and so on, these are the Japanese characters for" Don "the pronunciation Generally reflect the Chinese culture, especially culture of the Tang Dynasty of Japan's far-reaching impact on later Song, Yuan, Ming and Qing dynasties change, said Japan can not change China as "Don" habit did not change the Japanese Chinese culture of respect, admiration psychological. In 1713, Whitehead Arai from Edo shogunate orders, inquiries were drifting in Rome to talk too much about the history, a lot of opportunity to understand the world situation, a reference to China's "Kun Maps", Prepared for a title,"Song laid Introduction," in the world geography, history and more from his Department to listen to on the pronunciation of chi-na, to use katakana and that in the lower left-hand corner is attached to "Shina.
随着佛经的译入,日本逐渐了解"支那"所指并开始使用,如海空大师在其诗集《性灵集》中,有"支那台岳曼殊序"之句,当然,那时"支那一语带有模仿佛经译者的用法,但并不普遍,究其原因,主要是一直以来,日本人通常称中国为morokoshi、tohn等,这些都是日本人对汉字"唐"的读音,大体反映了中国文化,特别是唐朝文化对日本的深远影响,以致后来宋、元、明、清历代更迭,都无法更改日本人称中国为"唐"的习惯,也没改变日本人对中国文化崇敬、羡慕的心理。1713年,新井白石奉江户幕府之命,查询罗马的漂流者史多提,趁机了解了不少世界情势,参考了中国的《坤舆图说》,编写了一本题名为《宋览导言》的世界地理书,他把从史多提处听来的关于chi—na的读音,用片假名来表示并在左下角附以"支那字样。
