由於楔入劈拉法具有試件尺寸小、節省材料、試驗簡單方便、單人可操作等特點,測定混凝土斷裂韌度、斷裂能的實驗方法筆者建議採用楔入劈拉法。For shutters, the results show : 1 ) according to the formula p =, the theoretical value of is calculated by the effective velocity of the flow, and its engineering value is calculated by the arriving velocity of the flow, the relationship between the theoretical value of and its engineering value is 2 ) the smaller value of declining angle will result in the smaller pressure loss and smaller outlet velocities. as a result, the declining angle of 30 擄 or less is recommended in some places which need small wind velocity, such as broadcasting studio and library, and the declining angle of 45 擄 or less is recommended in places which need big wind velocity, such as cinema and office ; 3 ) the larger value of ratio between the wide of the shutter b and the space between two boards h ( b / h ) will result in the larger pressure loss and smaller outlet velocities. the range of b / h from 0. 8 to 2. 0 and the optimum value 1. 2 is recommended ; 4 ) the range of b from 10 mm to 50 nun and the optimum value 40 mm is recommended ; 5 ) the proper thickness of the boards 8 of the shutters is 1. 5 mm ; 6 ) cuneiform boards should replace the rectangle inlet boards of the shutters in order to obtain better ventilation
數值模擬採用fluent軟體,計算結果用excel進行處理,通過對大量數值工況進行數值模擬計算,結果表明:對于單側百葉風口,計算表明: 1 )對于公式p = ( ~ 2 ) 2 ,的理論計算值中定義為流體流經百葉風口內部時的速度,即有效速度,而工程上常使用流體的來流速度來計算,計算表明,的理論計算值與工程應用值的關系為( _ (理論) ) ( _ (工程) ) = 0 . 813 ; 2 )當來流速度一定時,擋板傾斜角度越小,壓力損失越小、出口速度越小;因此在要求進口風速比較小的場所,如播音室、圖書館等,宜採用擋板角度30的百葉風口;在要求進口風速比較大的場所,如電影院、辦公室等,百葉擋板的角度應選45 ; 3 )當來流速度一定時,百葉擋板的擋板寬度b與擋板間距h的比值b h越大,壓力損失越大,出口速度越小,計算表明,鑒于壓力損失、出口風速、板間形成渦流區的大小,百葉擋板的b h值取0 . 8到2 . 0之間, b h = 1 . 2為最佳值; 4 )當來流速度一定時,在計算的條件下,當百葉擋板寬度b = 40mm時,百葉擋板的阻力系數最小,考慮到渦流區等的影響,建議選用10mm b 50mm的百葉擋板;西安建築科技大學碩士學位論文5 )百葉擋板的厚度取為1 . sinln為好; 6 )百葉擋板的入口側可選用具有傾斜度的楔形擋板來代替矩形擋板,利用其較好的導流作用,可得到更好的出流效果。Hi this paper, concrete specimen of the same composite in shape of three - point - bend beam and wedge splitting specimen are tried out to ascertain the influence of specimen shape upon the fracture parameters
本文採用相同組分的混凝土材料以三點彎曲梁tpb和楔入劈拉試件ws作為比較對象驗證了試件形狀對斷裂參數的影響。Referring the sensitization monitoring method, the quantitative measurement by the wedge and the anti - dust performance expressed by optics density quantity had been developed. the concept of the indicator of anti - dust was put forward. at the same time, the anti - dust function was used as a index of optoelectronic sensor " s performance evaluation
深入研究了農用光電傳感器的抗塵問題,借鑒感光測定方法,開創性地提出了用標準光楔進行量化測量和用光學密度量化表示光電傳感器抗塵性能的方案,提出了抗塵指數的概念,並在此基礎上提出了將抗塵性能作為開關量光電傳感器的一項性能評價指標。分享友人
