熱軋鋼板和鋼帶的尺寸外形重量及允許偏差This thesis set forth the method and process of designing to kiln tyre using robust method. when constructing the math model, it was thought of that there were structure parameters, such as the tyre " media and width, and a series of uncontrolled factors ( contact stress, bend stress stiffness and temperature stress, and the aim is to optimize the weight of the tyre )
在構建數學模型中，考慮了輪帶內徑、輪帶寬度等結構參數以及輪帶的允用接觸應力、允用彎曲應力、輪帶的彈性模量、輪帶內外表面的溫差等不可控因素，以輪帶的接觸應力、彎曲應力、剛度溫度應力為約束條件，以輪帶的重量最輕為優化目標，通過改變輪帶的寬度以及輪帶的外徑進行參數優化設計。Examinations of steady status and analysis of dynamic experiments have been conducted on band - tube evaporator and parallel - flow condenser using r134a refrigerant. the steady examination show that the model error was under the allowable error, the inlet mass and enthalpy disturb experiments indicate that the subsection model, be good at reflecting the change of parameters of the heat exchanger, accord with the basic principle of thermodynamics theory and the actual work status. hence, the subsection simulation model research has important benefits both on theory and engineering application
在進行模擬試驗時，以使用r134a作製冷劑的管帶式蒸發器和平行流式冷凝器為對象，完成了穩態模擬計算、試驗和動態模擬分析，穩態計算結果和試驗數據對比表明，其誤差在允許范圍內；進口質量和焓值的擾動試驗結果表明：本文所建的區段式換熱器模擬模型，能很好的反映換熱器性能參數的動態變化，與系統熱動力學理論和冷凝器、蒸發器的實際工作過程基本一致。Wrought aluminium and aluminium alloy sheets and strips - tolerances on form and dimensions
鋁及鋁合金板帶材的尺寸允許偏差Measurement and characterization of surface texture is an important aspect of precision metrology. historically this has involved partitioning a profile into different wavelength regimes referred to as roughness, waviness and form followed by numerical quantization. parameters computed are then inspected for tolerance compliance to ensure a part performs its intended function. this approach is satisfactory when the specification has been carefully determined and the process is stable. however, when the manufacturing process is under development or when instability or modifications to the process invalidate specifications, there is a need to study surface finish parameters in relation to functional performance or process measures. in this context, the problem of surface texture classification and recognition are discussed. advanced techniques developed for this purpose along with applications are presented. also, the techniques discussed here will be useful across large bandwidth, from the characterization of nano scale to traditional micro scale surfaces
表面結構的測量與特徵描述是精密計量技術的一個重要方面，傳統上包括將輪廓情況根據不同的波長范圍劃分為粗糙度、波紋度和形狀及后續的數字量化.按算得的參數檢查它是否為公差允許，以保證零件執行其指定的功能.當技術特性已經經過仔細確定，並且其過程穩定時，該方法是令人滿意的;但是，當製造過程正在進行中或過程的不穩定、過程變化使技術特性失效時，就需要研究和功能表現及過程評定相關的表面參數.討論了表面結構的分類與識別問題.同時闡述了為此目的而開發的先進技術及其應用.所研究的技術對從納米尺度到傳統的微米尺度的較大帶寬范圍內的表面特徵描述都是有效的They firstly used compliance as an explanatory variable in the clinical trials. however, compliance often ca n ' t be measured exactly. following the simple model put forward by them, we develop a new model that allow compliance with random errors and separate the effectiveness of treatment from that of the compliance
然而，依從性往往很難被精確測得，因此基於他們提出的簡單模型，我們提出一個新的模型允許其中的依從性變量帶有量測誤差，並把治療（ treatment ）的效應和依從的效應分離出來，從而得到一個更符合實際的對照臨床試驗數據的ev模型。Dimensions, mass and permissible variations of hot rolled steel plates, sheets and strips
