摘    要
自從我國(guó)加入世界貿(mào)易組織以來(lái),我國(guó)獲得一個(gè)更加穩(wěn)定的國(guó)際貿(mào)易環(huán)境,各行各業(yè)都面臨著重大的機(jī)遇和挑戰(zhàn),肥料行業(yè)也不例外,BB肥作為實(shí)現(xiàn)測(cè)土配方施肥的重要肥種,越來(lái)越受到各方面的重視,中華合作時(shí)報(bào)•農(nóng)資??槕?yīng)時(shí)勢(shì)發(fā)展,組織業(yè)內(nèi)精英共聚一堂、各抒己見(jiàn),共同探討中國(guó)BB肥行業(yè)的發(fā)展思路,如果說(shuō)第一屆BB肥行業(yè)發(fā)展論壇的勝利召開(kāi)為我們指明了發(fā)展目標(biāo),那么此屆發(fā)展論壇的召開(kāi)應(yīng)該是探討達(dá)到這個(gè)目標(biāo)我們所需要做的努力。
中國(guó)BB肥行業(yè)的發(fā)展正處在一個(gè)十分關(guān)鍵的時(shí)期,面臨著各種機(jī)遇和挑戰(zhàn),機(jī)遇就是黨和政府對(duì)“三農(nóng)”問(wèn)題的高度重視、社會(huì)主義新農(nóng)村建設(shè)、國(guó)家對(duì)測(cè)土配方施肥工程的大力提倡,社會(huì)大環(huán)境給BB肥提供了廣闊的發(fā)展空間,農(nóng)資人的睿智為BB肥描繪了光明的發(fā)展前景,但是還要看到,隨著市場(chǎng)經(jīng)濟(jì)對(duì)農(nóng)資行業(yè)的浸透,WTO保護(hù)期的結(jié)束,國(guó)外農(nóng)資大鱷對(duì)中國(guó)農(nóng)資的分銷市場(chǎng)早已垂涎已久,我國(guó)化肥行業(yè)面臨著前所未有的挑戰(zhàn)。中國(guó)化肥行業(yè),特別是BB肥行業(yè),應(yīng)該團(tuán)結(jié)起來(lái)、發(fā)揮整體優(yōu)勢(shì),做大自己,抵御來(lái)自國(guó)外BB肥的強(qiáng)烈沖擊。涅盤(pán)之后得到的將是永生。
這樣,BB肥生產(chǎn)設(shè)備在我國(guó)也必然有很好的發(fā)展前景,本設(shè)計(jì)課題是(9-BBⅡ型)BB肥生產(chǎn)設(shè)備總體設(shè)計(jì)及傳動(dòng)系統(tǒng)設(shè)計(jì)。這個(gè)課題主要包括總體方案的確定和傳動(dòng)系統(tǒng)尺寸的確定及計(jì)算。完成這個(gè)課題,能夠讓我們學(xué)會(huì)如何將課堂上所學(xué)的理論知識(shí)更好的應(yīng)用到社會(huì)實(shí)踐中去。
由于水平有限。本論文中必然存在不少紕漏和錯(cuò)誤,敬請(qǐng)?jiān)u閱老師們批評(píng)指正。

Abstract
Since Chinese accession to the World Trade Organization, China access to a more stable international trading environment, businesses are faced with major opportunities and challenges, the fertilizer industry is no exception, BB fertilizer soil testing as an important fertilizer Fertilization species, the more to more attention from all sides, the Chinese co-operation conform to the trend of the times Times special agricultural development, the industry's elite organizations together to express their views and to discuss China's fertilizer industry BB thinking, if we say that the first Development Forum BB fertilizer industry victory held for us a clear development goals, so this session should be convened to develop the Forum is to explore to achieve this objective we need to do efforts.
BB fertilizer Industry in China's development is at a very critical period, facing a variety of opportunities and challenges, opportunities and the government is the party of "Three Rural Issues" attached great importance to building a new socialist countryside, the state soil testing Fertilization a strong proponent of the project, social environment to BB fertilizer provides a broad space for development of human wisdom for agricultural fertilizer BB painted a bright future, but would also like to see, with the market economy on the agricultural industry immersion, the end of protection period WTO, foreign agricultural predators of the distribution of China's agricultural market has long been coveted for a long time, China's fertilizer industry is faced with unprecedented challenges. China's chemical fertilizer industry, in particular, BB fertilizer industry should unite together to play the whole advantage of their big, fat BB from abroad against a strong impact.
So, BB fertilizer production facilities in China are bound to have good prospects for the development, the design issue is (9-BB Ⅱ type) BB fertilizer production equipment design and drive system design. The main subject of the overall program, including the identification and determination of transmission and calculation of the size. The completion of this subject, can we learn how to learn in class by the application of theoretical knowledge to the society a better practice.
In this paper, there is bound to be a lot of fault and error please comment criticism teachers.
