内收缩 meaning in English
internal shrinkage
Examples
- Consider a cloud of gas that is contracting inward under the attractive power of its own gravity
考虑一团云气在自身重力的吸引影响下向内收缩。 - In this thesis , hypersonic sidewall compression inlet ' s self - starting characteristics are numerical simulated and tested . with increasing mach number of inflow gradually , the hypersonic sidewall compression inlets can self - start . compared with the hypersonic sidewall compression inlet starting directly , characteristics are different . moving cowl , decreasing interior contraction ratio also can realize the hypersonic sidewall compression inlet ' s self - starting because of separation bubble on sidewall spilling out
其次,在数值模拟结果的基础上,设计了实验模型和装置并在马赫3 . 85的风洞中进行了移动唇口板减小内收缩比实现侧压式进气道自起动的风洞实验,验证了数值模拟的结果。 - Its unique compound formula can regulate the skin ph value , inhibit excessive sebum secretion , and decompose excessive greases through oxidizing reaction with greases on the skin surface ; the shrinking factor contained can smoothen and shrink pores inward , improve roughness arising from pore blocking , make skin look tight and fine
其独特的复合配方，能调节皮肤的酸碱度，抑制皮脂线分泌过多油脂，并能与皮肤表面的油脂发生氧化反应，使多馀油脂分解代谢，蕴含收敛因子更能畅通毛孔，令毛孔向内收缩，从而改善因毛孔阻塞而造成的粗糙问题，使肌肤看起来紧实细致。 - It is no effect on a sidewall compression inlet ' s starting characteristics while a starting sidewall compression inlet is moved cowl to increase interior contraction ratio appropriately . back pressure effect on characteristics of self - starting for hypersonic sidewall compression inlet is tested in mach 3 . 85 wind tunnel . the hypersonic sidewall compression inlet with interior contraction ratio 1 . 24 can self - start . unstart hypersonic sidewall compression inlet caused by high back pressure can self - start by moving cowl to decrease interior contraction ratio
最后,实验研究了反压对侧压式进气道自起动特性的影响,内收缩比1 . 24的侧压式进气道可以实现自起动并且实验验证了由于反压过高而不起动的侧压式进气道,通过移动唇口板以减小内收缩比可以实现侧压式进气道的自起动。
