中文拼音 [quēkǒukuòzhǎn]
缺口擴展
英文
notch propagation-
In this paper, the high - temperature low - cycle fatigue life and fatigue crack propagation life tests are carried on the cylindrical axial symmetry specimens having precrack or non - precrack with different types of notches of 16mnr steel in common use in the petrochemical industry contacting coke drum equipment, the stress / strain and the range of stress / strain of dangerous points are received through stress analysis of the specimens using finite element program under multi - axial stress state. at last, the equations of evaluating the high - temperature low - cycle fatigue life and the fatigue crack propagation life are found through using the least - square regression method
本文採用無預裂紋和帶預裂紋環狀缺口圓柱形試樣，進行了石化焦炭塔設備常用材料16mnr多維應力狀態下不同缺口形式的高溫低周疲勞總壽命試驗及裂紋擴展壽命試驗，並利用有限元程序對試樣缺口周圍及裂紋尖端附近進行了軸對稱多維應力狀態下的應力、應變場分析，來評價材料不同條件下的高溫低周疲勞總壽命和裂紋擴展壽命，最後利用最小二乘回歸方法，得到了該材料高溫低周疲勞總壽命和裂紋擴展壽命評價方程。And, withal, brew can make manufacturer provide their products to the market more quickly, they can self - defining his equipment conveniently and flexibly. the operator can write user interface in brew upper layer, thus upgrade its interface by wireless. in allusion to the fault of complex code construction, bad transplantable capability, bad extendable capability in traditional software of cmda handset module, this paper give the software design scheme by using brew platform. because of bad reusable capability, maintenance difficultly by using traditional dialog control in brew platform, this paper propose the design idea of windows control, solve upwards problem efficiently, reduce the cost of development greatly, enhance technology
本文針對傳統cdma手機模塊的上層應用軟體設計中存在的代碼結構復雜，可移植性差，可擴展性差等缺點，給出了以brew平臺為上層應用設計平臺的軟體設計方案，由於在brew平臺上使用對話框控制項設計軟體存在代碼復用性低，維護不易等困難，本文在此基礎上又提出了使用窗口機制的設計方法，有效的解決了上述問題，降低了研發成本，提高了終端設備製造的技術水平，使得採用該方案設計的產品與國內外同類產品相比更具有競爭力。With the increase of population, the development of the urban size, industry and agriculture, the groundwater demand increases sharply. and a series of environmental geologic problems such as regional groundwater table fall, water quality worsening, subsidence and so on, have emerged in the course of exploiting groundwater due to uncontrolled extraction and poor management
隨著人口的不斷增長，城市及工農業的迅速發展，人類對地下水的需求量急劇增加，然而由於對地下水資源缺乏正確評價與科學管理，常常盲目擴大開采，造成地下水位下降，水質惡化，地面塌陷等一系列環境地質問題。The study on high - temperature low - cycle fatigue life and fatigue crack propagation life under multi - axial stress state shows that the fatigue life and fatigue crack propagation life can be characterized by the equivalent plastic strain range p, the equivalent creep strain range c and the equivalent strain range, and do n ' t exit notch dependency, non - notch - dependency equations being given in the paper
） _ c和當量應變范圍（ ? ）進行多維應力狀態高溫低周疲勞總壽命及裂紋擴展壽命評價是可行的，且不存在缺口依存性。並給出無缺口依存性的疲勞總壽命評價方程。But along with the population increase, economic development and natural condition change, the dry and water deficient situation becomes increasingly serious, the drought occurrence frequency, scope and impacting area expand successively, in the meanwhile, some structural and systematic obstacles existed in long - term drought fighting work have emerged and the drought fighting work faces unprecedented trial
但是隨著我國人口增加，經濟發展和自然條件變化，我國乾旱缺水的形勢日益嚴峻，旱災發生的頻率、范圍和影響的領域不斷擴大，同時，長期抗旱工作中存在的一些體制、制度性障礙也顯露出來，抗旱工作面臨前所未有的考驗。Material notch sensitivity test is a method which is used for certain material to measure and estimate the capability of resisting cr ack growth on the occasion of existing load stress and notch
材料缺口敏感性試驗是測定或評價某一材料在靜載荷的應力條件下和有缺口的情況下，抵抗裂縫擴展能力的一種方法。According to the promises our nation took to enter wto, our country will continue to enlarge the foreign trade and this will lead to economic growth of our country. however, with the internationalization of manufacture and marketing, phenomena that products with defects produced in a country cause consumers " or users " personal damage or property loss in the importing country or a third country increases day by day. since there are many differences between the laws on product responsibility of different country, which will baffle our to develop foreign trade under wto rules as well as protect chinese consumers from products with defects, we must strengthen the research to the laws of product responsibility of other countries, especially the major nations of wto, and coordinate the relation between the law on product responsibility of our country and those of other countries, and, perfect the laws on product responsibility of our country
按照我國加入wto的承諾，我國將進一步擴大對外貿易，這對我國經濟增長無疑是一種促進，但隨著產品生產和銷售的國際化，一國生產的缺陷產品在進口國甚至第三國導致消費者、使用者人身傷害、財產損失的現象也日漸增多，而各國的產品責任法又千差萬別，這些法律沖突的存在會阻礙我國在wto規則下發展對外貿易，同時也不利於對我國消費者的保護，因此，我們必須加強對世界各國，尤其是wto主要成員國產品責任法律制度的研究，協調我國與各國產品責任法的關系，完善我國產品責任法律制度。分享友人
