But when the heat load of rotor increases , the ratio of the heat bring by the axial direction gas - flow to the total heat load decreases 但隨著轉(zhuǎn)子發(fā)熱量增大,氣隙軸向風量帶走熱量占總熱量的比例下降。
Maintaining power delivery as load increases in the morning , keeping it within security limits during daily peaks , and managing load decreases at night are just some of the tasks the control system will perform 控制系統(tǒng)將負責的一些任務就是在上午負荷增加的時候維持電力輸送,在每日高峰時保持在安全限度內(nèi),以及管理晚上負荷的降低。
The main problems existed in the measured buildings conclude : low energy efficiency plants , low eer when the cooling load decreased during the night period in hotels , bad management , dissatisfied indoor air quality , low efficient water system and so on . if we can avoid these problems , a lot of energy can be saved 重慶市公共建筑主要存在的問題有:設備效率達不到額定值,冷水機組冷量配備過大,酒店在夜間低負荷運行時空調(diào)系統(tǒng)能效比( eer )很低,室內(nèi)環(huán)境很不令人滿意,水系統(tǒng)輸送效率低下,跑冒滴漏現(xiàn)象嚴重,運行管理混亂等。
The result indicate that the influences of geometrical nonlinearity is different to the structure critical load under different load cases . under the live uniform load , the structure critical load decreases 10 % after considering the geometric nonlinearity ; and under the live uniform load or concentrated load act on half bridge , the structure critical load decreases 35 . 38 % or 74 . 08 % after considering the geometric nonlinearity 計算結果表明,在不同的加載工況下,幾何非線性對結構的臨界荷載影響程度不同,幾何非線性對全橋均布活荷載作用下的臨界荷載影響較小,考慮幾何非線性后,臨界荷載僅下降了10 % ,而在半橋均布活荷載和集中荷載作用下,幾何非線性對其臨界荷載影響很大,考慮后其臨界荷載分別下降了35 . 38 %和74 . 08 % 。
Test results show that the steel fiber in concrete have more effectiveness on improving the splitting tensile strength and the flexural strength in the early age than after its hardening ; the flexural modulus of elasticity of sfrc are higher than the plain concrete at different ages while their compressive modulus of elasticity are almost the same . it ' s also shown that , similar to the plain concrete , the early - age loading decreases the strengths of sfrc , but , with the increase of the contents of the steel fiber things are getting better , especially for the splitting tensile strength and the flexural strength 試驗結果表明:與性能穩(wěn)定之后相比,在混凝土中摻入鋼纖維對它的早期劈裂抗拉強度和抗折強度有尤為顯著的提高作用;對各齡期的受壓彈性模量影響不大,而對提高抗折彈性模量有一定的效果;與素混凝土試件相同,在早期(強度達到28天強度的85前)對鋼纖維混凝土試件施加荷載會對它的各種強度產(chǎn)生一定的不利影響,但是摻入鋼纖維可以減輕這種不利影響,尤其對劈裂抗拉強度和抗折強度作用突出,并且含纖率越高,效果越明顯。
