雖然其他可能導致支氣管收縮的可能性較小，但也應考慮，包括右主支氣管阻塞、麻醉深度不足、氣胸、肺水腫和肺栓塞[ 4 ] 。The study has also found that platelet activation can be reduced by nasal continuous positive airway pressure ( cpap ) treatment. although the major indication of cpap treatment is to relieve symptoms such as disabling daytime sleepiness, the reduction in platelet activation should be regarded as a bonus benefit especially with the growing evidence of cardiovascular consequences related to osa. it is important to treat symptomatic patients with osa early, with the potential advantage of preventing cardiovascular complications such as stroke
該研究同時指出，使用鼻腔式正氣壓治療（ continuouspositiveairwaypressure ， cpap ） ，能有效減低血小板的活躍度， cpap經已獲證能紓緩阻塞性睡眠窒息癥的病情，例如減少日間渴睡的情況；長遠來說，可以預防和減低患上阻塞性睡眠窒息癥出現心血管並發癥的風險。After thermodynamic calculation on several operation conditions of the furnace, cold - state flow and resistance mensuration, the combustion of the tubular - furnace hearth was changed into swirl and addition of radiate cylinder and oxygen content detection minish 1. 25 surplus air to less than 1. 15, improving the combustion condition and convection and radiate heat transfer efficacy, resuling in reducing the waste - gas temperature 45, decreasing exhaust gas loss, and saving fuel by 6 %
摘要通過對加熱爐幾種工況進行熱力計算、冷態試驗的流場分佈及阻力測定和熱態試驗的爐膛溫度場分佈及管壁溫度等參數的測定，確定將管式加熱爐爐膛內直流燃燒改為旋流場燃燒和增加輻射筒，增設煙氣含氧量分析，可以將燃燒的過剩空氣系數從1 . 35減小到1 . 15以下，極好地改善爐膛內的燃燒狀況和對流輻射傳熱效果，從而降低排煙溫度45 ，減少加熱爐排煙損失，節約了煤氣量6 %以上。Generally, the membrane thickness is much larger than the pore dimension. therefore, the resistance of the pore channel was the control resistance of the membrane diffusion process. while the existences of the stephen diffusion and pore interaction well explained the reason why the total membrane surface would be used as the interfacial area through where the mass transport took place
盡管由於膜的厚度比孔的尺寸要大很多， stephen擴散以及孔之間的相互作用對通過膜的總擴散阻力影響很小，但它們存在的結果是使整個膜表面的氣體濃度趨於一致。When the temperature to gas pipelines, temperature packets of material expansion, the pressure rise, inflation pressures are rising corrugated box, corrugated promote the expansion thrust to overcome the spring - loaded pole resistance, the ball - type valve opened for big change ; when the gas pipeline to reduce the temperature, temperature of the material swelling up, the pressure lowered inflation corrugated box pressure also reduced, spring - loaded pole compressed corrugated of resistance to thrust, spherical valves open for smaller ; this constant push and pull adjustment for the balance, as long as refrigeration cycle continue
當回氣管道溫度升高，感溫包內的物質膨脹，壓力升高，膨脹波紋箱內壓力也升高，波紋腔膨脹推動推力桿克服彈簧阻力，球型閥開度變大；當回氣管道溫度減低，感溫包內的物質膨脹，壓力降低，膨脹波紋箱內壓力也降低，彈簧阻力推動推力桿壓縮波紋腔，球型閥開度變小；如此不斷的進行推拉調整平衡，只要製冷循環繼續下去。In order to know the relationship between gas - content and pipeline ' s pressure drop, the thesis deduces the pressure drop calculating equations based on uniform flow pattern and separating flow pattern. the equations show that pressure drop is made up of three parts, that is, friction resistance effect, gas acceleration effect and the gravity effect. and the research has shown that the gas has little effect on pressure drop. in the horizontal pipeline, the resistance effect must be overmatched the acceleration effect
為探討加入的氣體對管道壓力的影響，本文基於分相流和均相流兩種模型分別推導了三相流管道的壓降公式，表明無論是分相流模型，還是均勻流模型，管道內流體總的壓降是由三項組成的，即摩擦項、加速項和重力項，並得出了加氣對管壓變化不大的結論，所以認為在水平管道中，要獲得有效的減阻，則要使摩擦阻力分量的減小效應大於漿體加氣的加速效應。To avoid accidents such as choking, parents should keep small items such as peanuts, buttons, candy, and so on away from a baby ' s reach
為避免孩子發生氣管異物阻塞的意外，居家環境中應避免小小東西的散落，例如：花生米、鈕扣、糖果. . .等等。The experimental results show that this type of filter is do a kind of high efficiency and low resistance, which under its nominal air flow rate ( 1000m / h ) and when the diameter of filter tube is 30mm and the length of it is 1. 1m, its resistance is the lowest, only 50pa
實驗結果表明：該種多管式高效空氣過濾器確是一種高效低阻的過濾器，其在額定風量下（ 1000m ~ 3 h ） ，濾管直徑為30mm ，袋長為1 . 1m的過濾器阻力最小，只有50pa 。The model analysis of the deployed beams were studied in both theory way and simulation way. the differences of the beams in different pressures were studied. investigations showed that the method of modeling for short and long rolled beams is doable ; the process of fold maybe lead so large displacement and stress that membrane is damaged at local areas, ration and material wrinkle generates,
研究結果表明:本文提出的分別針對短、長捲曲折疊充氣管的建模方法是有效的;在充氣管展開過程中，充氣速度越大，展開的速度越快，但由於阻尼損耗，二者並非線性關系;充氣速度過大不利於結構展開過程的穩定性;充氣支撐管的氣壓越大其固有頻率越高，但影響效果很小。分享友人
