    在實際的工程測量中最容易獲取的結構態參數就是頻率,但是頻率對質量、剛度的變具有弱靈敏性,這使得即使結構的破損程度達到了限破損程度,頻率的變也很難被測試系統識別。
  4. The article has researched the intention of agricultural industrialization which is guided by market and mainstay enterprises, based on agricultural product base organized by a lot of families, and characterized by joint management and mutual benefit. it also realized production specialization, product commercialization, service socialization and etc. the article has also researched the existing conditions of agricultural industrialization both at home and abroad. although it is different in national conditions and actual practice, the developed countries follows the market economic law and naturally steps on the road of agricultural industrialization. as the continuous reforming and opening up, china actively explores and enhances the management level of agricultural industrialization. the writer uses system changing theory, scale management theory, trade expense theory. market system theory and industrial economics theory, to put forward the main type of mainstay enterprises, which is divided by ownership, organization form, contact form and product. the writer thinks that development of mainstay enterprises can promote effective joining between small production and big market, the developing of high - benefit agriculture, establishing trade / industry / agriculture operation system, region economics and joining process between urban area and rural area. the existing conditions in strengthening the mainstay enterprises in zhaoyuan embodies continuous expanding in scale. continuous widening in fields, continuous enhancing in benefits, continuous improving in techology and quality. by finding the problem and shortage in product quality, developing ability and scale strength, the article has put forward the following views : face to market and enhance quality and techological content of agricultural products ; enforce flexible policy and investments ; establish fair and reasonable benefits joining system. the article has also put forward the countermeasures and suggestions on enhancing the enterprises ' management level

    文章研究了農業產業經營的內涵,明確其以市場為導向、以龍頭企業為依託、以一大批農戶組成的農產品生產基地為基礎,形成農工商有機結合、風險共擔、利益均沾的本質特點,表現出生產專業、經營一體、企業規、產品商品、服務社會等特徵。分析了國內外產業經營的現狀,認為盡管各國的國情不同,具體的做法和叫法不盡相同,但是經濟發達國家都遵循市場經濟規律,很自然走上了農業產業經營的道路,發展中國家紛紛仿效,中國也隨著改革開放不斷深入,積探索發展提高農業產業經營水平。作者運用制度變遷理論、規經營理論、交易費用理論、市場機制理論和產業經濟學理論,提出了龍頭企業從所有制形式、從組織形式、從聯系方式及從產品上劃分的主要類型;認為發展龍頭企業有促進小生產與大市場的有效對接、推優質高效農業縱深發展、建立貿工農一體運行機制、興區域經濟、加速城鄉一體進程等作用;考察了招遠市壯大龍頭企業推進農業產業的現狀,表現在規不斷擴大、領域不斷拓寬、效益不斷提高、技術不斷改進、質量不斷提高等方面;找出了龍頭企業產品質量上、開發能力上、規實力上和行業自律上的問題和差距,提出了要面向市場,努力提高農產品的質量和科技含量,多策並舉,搞活投入機制,建立公平合理的利益聯結機制,加強行業自律,提高企業經營管理水平等對策和建議。
