Firstly, the performance is calculated at the design point of the ws - 9 aeroengine by using the numerical model established. secondly, after obtaining the performance coupling parameters, the steady - state performance of the non - designed points is caculated. third, respectively make the limitation of rotate speed of the high pressure rotor and low pressure rotor equal to corresponding parameters of designed point, after the data calculated compared with those of designed point and actual testing of the manufactory, the error is obtained
首先，用所建立的發動機數學模型計算了發動機在設計點的各項性能，第二，根據發動機各部件的耦合特性參數計算得到發動機在非設計點狀態下的各項穩態性能，第三，分別設定限制高壓轉子轉速和低壓轉子轉速逼近設計點條件下對應的參數，將計算得到的性能數據與設計點性能進行了比較，並將非設計點的計算結果與生產試車過程實測的性能數據進行對比，給出了該穩態模型計算結果與實際試車數據的誤差。 -
The original design was intermediate vapor 42t / h, but the actual output is 30 - 35t / h, at the same time the temperature and pressure of the vapor are unstable, it affects the economic efficiency, the reason were the collecting dust on the heat area and serious corrision, they led to the decrease of the boiler load, and need stop to washing the dust, the article deals with the reform of the exhaust gas boiler, at the basic of the design condition, after thermo calculation, flute gas, resistence calculationand strenth calculation, the structure of the heat surface had been rearranged, then the proof calculation was done
原設計產中壓蒸汽42噸時，但投運后只產30 - 35噸時，並且蒸汽溫度和壓力均不穩定，影響到經濟效益。其原因是受熱面積灰和腐蝕嚴重，影響傳熱使鍋爐負荷下降，不能長時間運行，需停產清理積灰。本論文針對此余熱鍋爐的技術改造，在給定設計條件基礎上，通過熱力計算，煙氣阻力計算和強度計算，對鍋爐受熱面結構重新布置，然後再作校核計算。 -
The conclusion is that it is more similar to practical soil pressure distribution if shear strength parameters are used which are obtained by the experiments that can simulate the actual process of active soil during excavation. so it is more reasonable to use shear strength parameters obtained by tri - axial experiments that can simulate the process of excavation in design of retaining structure
本論文得出的結論是：用模擬基坑開挖實際應力路徑的試驗方法得出的抗剪強度指標計算基坑側土壓力分佈，與實際情況更為接近，在基坑支護設計中，應該盡量使用模擬基坑開挖實際應力路徑的三軸試驗方法確定土體抗剪強度指標。
