塑變滯后 的英文怎麼說
中文拼音 [sùbiànzhìhòu]
塑變滯后
英文
p asticity hysteresis-
Performance for a piezoresistive transducer pressure sensor to thermal and pressure environments can be predicted by finite element method. a simplified 1 / 8 model, considering silicon dioxide and nitride process as well as stack anodic bonding and adhesive bonding processes, was developed. the fem results were found to be comparable to experimental data. case studies suggested that pyrex stack induces certain amount of non - linearity, while it isolates hard epoxy nonlinear effect. flexible epoxy bonding or soft adhesive bonding is preferred to the packaging process. the viscoelasticity and viscoplasticity of bonding material will result in hysteresis and drift errors to sensor output. however, soft adhesive s influence on sensor can be ignored under relative stable environments. more over, detailed design and process information will help to improve modeling application
熱、壓環境下壓阻變換壓力傳感器的性能可以通過有限元方法預測.這里研究了簡化的1 / 8模型，模型考慮了二氧化硅和氮化硅生成過程及堆陽極鍵合和膠粘結合過程.結果發現有限元預測結果和實驗數據具有可比性.範例研究表明，硼硅堆導致產生一定的非線性，但它隔離了硬環氧樹脂的非線性.在包裝過程中最好使用柔性環氧黏合或軟黏膠性結合.黏合材料的黏彈性和黏塑性將會導致傳感器輸出的滯后和漂移誤差.然而，在相對穩定的環境下，軟黏合劑對傳感器的影響可以忽略.此外，詳細的設計和過程信息有助於提高模型的適用性Abstract : recent experimental investigations have demonstrated that the pre - deformation of shape memory alloys results in martensite stabilization opposing reverse transformation, hence leading to the expansion of transformation hysteresis
文摘:形狀記憶合金經適當溫度下的塑性變形可以有效地提高馬氏體的穩定性，從而使相變滯后得以大幅度提高。It is indicated that the relaxation of elastic energy stored during the forward martensitic transformation is responsible for the expansion of transformation hysteresis, which is in good agreement with experimental results associated with the hysteresis enlargement by deformation of niti, niti - based and cualni shape memory alloys
結果表明，塑性變形產生的位錯以及變形的第二相顆粒對逆馬氏體相變溫度的提高具有一定作用，但塑性變形導致應變能釋放才是形變提高形狀記憶合金相變滯后的主導因素。If there are high temperature gradient between cool liner and hot liner, compressive plastic strain appear at that transient time, which lead to gas film wall bearing high tensile stress at high temperature. high tensile stress is one of main reasons which destroy combustor
分析表明，起動過程中由於熱傳導滯后引發的溫度梯度可以導致火焰筒氣膜唇邊在起動瞬間發生較大的壓縮塑性應變，進而使得該區域在工作時承受較高水平的拉伸應力，高的拉應力會導致火焰筒萌生裂紋。Under strongly random exterior excitation, most structures will undergo elastic - plastic stage and show hysteretic characteristics, the vibration of structure expresses nonlinear random feature. therefore nonlinear model must be utilized in order to describe the behavior of this kind of structure, also the theory and methodologies of nonlinear random vibration are necessary for analyzing their response
許多工程結構在強烈隨機外激勵下都將進入彈塑性變形狀態，表現出滯后特性，結構的振動表現為非線性隨機振動，因此必須用非線性模型來描述結構，並用非線性隨機振動的理論和方法來進行分析。分享友人
