In order to analyze their psychological characteristics comprehensively, the research was carried out on 152 bearing and unboarding children in wenzhou, which adopt group intelligence test for students, eysenck personality questionnaire ( epq ), group thematic test for students ( t - tat ) and symptom checklist 90 ( scl - 90 ). it is shown that these children has developed their unique characteristics
為了全面了解寄託兒童的心理特點，本研究採用中小學團體智力篩選測驗、艾森克人格問卷（兒童版） 、學生團體主題統覺測驗（ g ? tat ）和癥狀自評量表（ scl ? 90 ）四個量表對溫州市152名寄託兒童和一般兒童進行調查分析，結果表明，寄託兒童已經形成了自己的特徵。The analysis on the test result shows that the temperature distribution in cfst members caused by solar radiation is nonlinear, and the nonlinear character is most evident when center point of concrete gets its lowest temperature. the temperature of the center point is affected by various directions, especially the strong potential. in the side exposed to the sun in the afternoon, apart from the center point, temperature varies laggardly when the point of concrete in the same series is more close to the center
結果表明，日照作用下截面的溫度場為非均勻場，混凝土中心的溫度達到最小值時，截面溫度場的非線性特性最明顯，圓心點的溫度受各個方向溫度的共同作用，更多地受到強勢方向的影響;下午時處在向陽面的各系列，同一系列上混凝土各點溫度變化隨直徑縮小趨緩，越靠近圓心，溫度變化越緩和，對外部環境（包括氣溫與日照）的影響呈滯后現象越明顯;而在下午時處在背陰面的各系列除圓心點外，同一系列上越靠近圓心的混凝土測點，溫度變化越緩和。Aimed at the present status of detecting oil storage fluid, the article advances a method which utilizes the dramatic feature of optical fiber sensor to develop the optical fiber liquid height meter, and to substitute the manual examination means, and supplements the optical fiber liquid overhead alarm equipment, the optical fiber grating temperature sensor, and uses the network technique to build the optical fiber sensing safety supervisory system to realize the intelligent examination of oil - tank area, thereby avoids or decreases occurrence and the risk of accident, and supplies the reliable guarantee for the big - and - middle - sized tank farm safe production
本文針對儲油液位的檢測現狀，提出利用光纖傳感器的特點研製光纖液位計，取代手工檢測的方法，輔以光纖液位高位報警器，光纖溫度傳感器，並應用網路技術構建光纖傳感安全監測系統，實現石油罐區的智能監測，從而避免或減少事故的發生，降低風險，為大中型油庫的安全生產管理提供可靠的保障。本文首先對安全監測系統中的核心硬體? ?光纖液位計的工作原理及特點進行了介紹。In this paper, difficulties such as the design of hts microwave passive component, the lithography technology, encapsulation and testing at low temperature etc. are solved. a hts delayline with center frequency at 4ghz, bandwidth of 4ghz is manufactured and tested. it ’ s group delay is larger than 10 ns
本文在解決高溫超導微波無源器件的設計、光刻工藝、密封封裝和低溫測量等難點的同時，對一個f _ 0 （中心頻率）為4ghz ，帶寬4ghz的高溫超導延遲線進行加工、封裝、測量，群時延大於10ns 。It can also determine the fault spot and reason. this technology has been used in some technological fields and proved efficient. it has promoted the revolution of maintance system and the historial protection is replaced by preventive maintenance. with this technology, we can improve the reliability of machine and decrease the maintance fee. recently, reserch has pick up a fervent pace in the area of fault diagnosis of electrical machines. the paper simply analyzes the fault reason of electrical machines, stressly describes and explores the methods of condition monitoring and fault diagnosis such as partial discharge, stator current, rotating speed, vibration etc. fault prognosis is now include diagnostic feature, reason, spot. prodigious improvement in signal processing hardware and software has made this possible. primarily, these techniques depend on locating specific harmonic components of the fault. these harmonic components are usually diffirent for diffirent types of faults. automated tools such as fuzzy logic based system is also simply presented in the paper
本文從絕緣結構的故障機理入手，以絕緣結構故障的典型特徵? ?局部放電為研究對象，重點討論局部放電的在線監測方法、適用場合併比較它們的優缺點；在分析籠型異步電機轉子斷條在線監測的定子電流監測方法后，根據其缺陷，本文探討了溫升不平衡法、希爾伯特變換數字濾波、小波包分析法的原理及優點；以電機軸承、氣隙偏心等故障為研究對象，通過對電機振動和轉速頻率的檢測，診斷電機的故障類型；本文的重點工作是將人工智慧技術中的模糊技術應用於電機的狀態監測和故障診斷中，力求使電機故障診斷更接近人工智慧化；最後，本文對電機狀態監測和故障診斷系統進行了硬體和軟體初步設計，為實現預測維修提供了有效的技術手段。分享友人
