【正文】 。 and whoknows but that we shall hearken to you? If then our request is afair one, please to accept our challenge. Cle. But is there any difficulty in proving the existence of theGods? Ath. How would you prove it? Cle. How ? In the first place, the earth and the sun, and the starsand the universe, and the fair order of the seasons, and thedivision of them into years and months, furnish proofs of theirexistence。 and the f ifth kind is when the violation ofthe civil rights of an individual demands reparation. There shouldbe a mon law embracing all these cases. For we have already said ingeneral terms what shall be the punishment of sacrilege, whetherfraudulent or violent, and now we have to determine what is to bethe punishment of those w ho speak or act insolently toward the G first we must give them an admonition which may be in thefollowing terms:No one who in obedience to the laws believed thatthere were Gods, ever intentionally did any unholy act, or uttered anyunlawf ul word。 the idols of parasites。 and virtue was never so beholding to human nature, as it received his due at the second hand. Neither had the fame of Cicero, Seneca, Plinius Secundus, borne her age so well, if it had not been joined with some vanity in themselves: like unto varnish, that makes sealings not only shine, but last But all this while, when I speak of vainglory, I mean not of that property, that Tacitus doth attribute to Mucianus。 for all bravery stands upon parisons. They must needs be violent, to make good their own vaunts. Neither can they be secret, and therefore not effectual。 the fly sat upon the axletree of the chariot wheel, and said. What a dust do I raise? So are there some vain persons, that whatsoever goeths indeed! They could tell us something worth hearing, if they only knew how to talk.

In nearly 2021 years of development, the people have made the massive discussions to the auction theory and technology. With the development of puter work technology, to improve work efficiency of public bidding and provide guarantee for preventing corruption and clean government, traditional online auction tender to the tender transition. So bidding and tendering technology based on Web bee the development direction of information systems. This paper analyses the current situation and development trend of bidding and tendering technology. An explanation of , SQL database technology, B/S structure was introduced. The general flowchart of the system designing plan and describes the system functions are described. In this paper, the design concept of setting up bidding and tendering system based on Web is presented and attempted by adopting new technology and tools based on and SQL2021, the system architecture of Bidding and Tendering system based on B/S structure is constructed Key words: Bid and Tender。 本系統(tǒng)以保證招投標活動的公平 、公正和公開的原則,采用競爭的手段實現大宗貨物和服務的采購最優(yōu)化的方式。 隨著網絡技術的不斷發(fā)展,招投標由原來手工操作方式逐步轉變到Inter 網上進行的方式,網上招投標系統(tǒng)是指招投標過程中各個角色,如供應商、招標機構等連接起來,企業(yè)、機關和個人網上傳遞投標數據,評標、開標均采用電子手段,通過網絡發(fā)布 中標結果的一種投標方式。 因此從 總體來看,目前世界各國和有關國際組織的有關采購法律、規(guī)則都規(guī)定了公開招 標、邀請招標、議標等三種招標投標方式。 (1).NET戰(zhàn)略, .NET戰(zhàn)略基于這樣一種想法,即所有的設備在將來都會通過Inter連接在一起,而 .NET就會為 Inter網絡上提供的一種服務。當數據庫能夠容納幾乎所有數據之后,我們必然面臨的一個問題是如何快速獲得我們需要的數據。 以目前的技術看,局域網建立的 B/S結構網絡應用,通過 Inter/Intra模式下數據庫應用,相對易于把握、成本也是較低的。如果用戶還沒有自己的帳號,需要首先進行注冊,單擊首頁中相應的鏈接,進入注冊
