Travel time is the key point of system, its measure quality decides the survey precision of the stress. time to digital convertor ( tdc ) was applied to accomplish the precision time interval measurement. at the same time, one transmitter - two receivers probe arrangement and zero - crossing detecting method were also applied to reduce the errors in measurement
傳播聲時是整個測量系統中的關鍵量，其測量水平決定應力的測量精度，對此本文採用時間-數字轉換器（ timetodigitalconvertor ， tdc ）完成高精度時間間隔測量，在實現過程中又分別採用「單端發射-雙端接收」的探頭布局模式和「過零檢測」手段來降低系統檢測誤差。Real madrid certainly have the funds to make such an offer after they recently finalised the sale of their television rights and will earn over & pound ; 65m in the next two years alone
在皇馬將接下來的兩年的電視轉播權賣了6500萬英鎊后，他們完全有能力支付這個價。In the process of building and using the mass concrete structures, because of the effect of out - side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance using nondestructive testing method to test the concrete ' s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseases this dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic fem to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, researched the principles of the first - arriving waves " phase when the cracks " depths are not same, obtained the relation between the inversion point and the cracks " depth, which has the direction sense in the application of projects, the second part of this dissertation is ct, which used the ultrasonic wave running through the tested - substance to get arriving - time of the ultrasonic wave, then inverse the image this dissertation drawed one ct program which can well present the different little cells " ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested - substance, ct has the better using foreground.
在混凝土結構的施工及使用過程中，由於受其自身及外界各種因素的影響，常常會產生一些缺陷，對結構物的承載能力和耐久性造成嚴重影響，採用無損檢測技術進行質量檢測和健康診斷，這對混凝土結構開展安全、穩定性評估以及病害隱患治理研究具有重要意義。本論文主要針對大體積混凝土結構缺陷的檢測方法展開研究工作，重點討論了超聲波法檢測混凝土結構裂縫的基本原理和方法及其特點、適用范圍，運用動力有限元數值模擬其檢測過程，探討了有裂縫缺陷的混凝土結構在脈沖荷載作用下彈性波的傳播及其變化特徵，研究了不同裂縫深度下首波相位變化規律，得出了反轉臨界點與裂縫深度之間的關系，這對實際工程應用具有指導意義。聲波ct是一種新的無損檢測技術，它是利用聲波穿透被檢測體獲取聲波接收時間，來進行計算機反演成像的技術。But the conditions of the agricultural expanding and its existing problems, the structure and distribution of the agricultural information resources, the agricultural management ' s systems, the economic conditions of the rural society and the cultural and educational standard, the public facilities of agriculture and countrysides, etc, all the above factors are affecting the agricultural information spreading and its communication directly or indirectly, interfering the spreading passages, slowing down the spreading speeds, reducing its efficiency, etc. therefore, we must improve the interior and exterior environment that affecting agricultural expanding, agric ultural information spreading and its service, take such measures as developing the science and education of agriculture and countryside, improving agricultural expanding system and organism, enforcing the basic facilities " construction of agriculture and countryside, enforcing the information resources " construction, etc, so that we can speed up the information spreading, promote the agricultural creative diffusing, improve the scientific standards of agricultural production, promote the development of agricultural economy, increase the farmer ' s income, and make the rural society develop rapidly
但是，農業發展與農業推廣工作的狀況與其存在的問題以及農業信息資源結構與布局、農業管理體制與機制、農村經濟社會條件與文化教育水平、農業和農村公共設施、農業推廣的行政或組織環境等方面的環境因素，直接或間接地制約了農業推廣信息傳播與交流及其服務工作的順利開展，障礙了信息傳播通道，阻滯了信息傳播速度，降低了信息傳播效益，不利於農業信息產業化和農業信息水平的發展與提高。因此，必須著手改善影響農業推廣工作、農業信息傳播與服務工作的內外環境，採取諸如大力發展農業與農村科教事業、創新農業推廣體制和機制、加強農業和農村基礎設施建設、加強信息資源建設、發展農業信息產業化等相應對策措施，才能加快農業信息傳播，促進農業創新擴散和成果轉化，提高農業生產的科技水平，推動農業經濟發展和農民收入提高以及農村社會的全面進步。分享友人
