Abstract : the analysis technology of components quality and reliability growth was presented in this paper , in terms of failure information collection and analysis, failure analysis, destructive physical analysis, internal residual gas analysis of hermetic packaging, the relation analysis of failure mode and process, failure mode and effects analysis
摘要:從元器件可靠性物理分析技術角度,系統地闡述了失效信息的收集與分析、失效分析、破壞性物理分析、密封器件內部氣氛分析、失效模式及機理與工藝的相關性分析、失效模式與影響分析等元器件的質量與可靠性分析技術。The immersion electrical heater is chiefly applied in the direct contact mode of fluid heating. it features fast heat exchange and high thermal efficiency. it has the varieties of water heater, oil heater and gas heater. its heating element power density, i. e. the power per unit of heating area of the heating element, is an important parameter of the electrical heating element, which has a direct bearing on the performance and working life. the working out of the value is a highly specialized problem, being under the influence of many factors ( media flow rate, tempt, physical and chemical properties and direction in which the medium flows past the element etc )
浸入式電加熱器主要用於直接對流體接觸加熱的場合,具有熱交換快,熱效率高等特點,分為水用加熱器、油用加熱器、氣體用加熱器,加熱元件的功率密度:即電加熱元件單位發熱面積上的功率,它是電加熱元件極重要的參數,直接影響加熱器的使用性能及使用壽命,它的取值是一個非常專業的問題,受到許多因素的影響(如介質的流速、溫度、物理和化學性質及介質流過加熱元件的方向等等) 。The experimental results showed that there was a significant difference between root yield and sugar yield under different planting patterns, the root yield and sugar yield were increased by 36. 7 % and 39. 8 % respectively, and the net profit was increased by 1602 yuan per ha for two lines within wide row with paper - pot in comparison with the treat of direct sowing in normal row
摘要試驗結果表明,在同等條件下,由於栽培方式不同,密度不同,塊根產量、產糖量差異較大,以紙筒大壟雙行為最好,甜菜塊根產量、產糖量比對照小壟直播分別提高36 . 7 % 、 39 . 8 % ,每公項純增效益1602元。
