31, There are four technical problems on modern high speed comber, and the mechanical vibration and airflow in working field are calculated.

32, Adopted unique ventilation system and non - carbonate direct current motor stabilize the hot airflow.

33, The DB - PB AIR SHOWER PASS BOX characterizes as double lock between the air brake and door , which enable the box has a better airflow prevention ability than trsditional pass box .

34, A housing includes an air inlet , an air outlet and an airflow path there through.

35, But oversize airflow velocity may accelerate weight losses of the cargos and the loading gap may be restricted by the loadage.

36, According to the airflow tilt angle sensitive element and its output feature, a mathematic model on restraining acceleration interference is built.

37, Secondly, coarse composts should be separated by airflow density separation system.

38, Field testing of air curtain with muti - parallel fans on ejecting airflow was conducted in Jinchuan's NO.

39, Dust acting as a thermal insulator and impeding airflow, thereby reducing heat sink and fan performance.

40, However, these vortices are unstable; slight changes in airflow can disrupt them, removing the lift that they provide.

41, The unit is used to realized the airflow conveying of granulated resign ny mens of the technology of low vacuum. It can be used with a hopper dryer to automatize dry material-supplying.

42, Baffle positioning shall be tuned in factory for most optimal airflow characteristic.

43, The airflow circulating system can be used for an wall hanging type air conditioner indoor set, an air curtain machine, an air heater and a dehumidifier.

44, The dynamization of airflow is an important direction to improve the indoor thermal environment and the human thermal comfort.

45, Sunlight, thermal radiation[Sentencedict.com ], shielding and airflow all affect the comfortableness of the space.

46, The angle of attack of the high - aspect - ratio wings varies largely as the airflow rounds the airfoil.

47, Mixing ventilation is widely used in the traditional catering kitchen, resulting in the serious pollution in cooking fumes, high temperature, unreasonable airflow and high load fluctuation.

48, Adopted unique ventilation system and rotational direct current motor stabilize the hot airflow.

49, The diagonal branch of ventilation network has the characteristic of instable airflow.

50, Advanced MCU control technology has light touch interface including start control, temperature control and airflow control to achieve safety and reliable operation.

51, The law of distribution of dense airflow and lean airflow is gained when changing blade width and blade arrangement by experiments.

52, The experimental results show that acoustic resistance of perforated plate is related to plate thickness, aperture diameter, numbers of aperture,(sentencedict.com) acoustic frequency and airflow velocity.

53, According to the principle of conservation, differential equation which can describe airflow temperature distribution in state of turbulent flow in mine working face is deduced.

54, Obstructive sleep apnea hypopnea syndrome(OSAHS) is characterized by recurrent episodes of airflow reduction(hypopnea) or cessation(apnea) during sleep or daytime somnolence.

55, Calculating results show that it is available to study the tiny particle diffusion by means of measuring and analyzing the room airflow movement in an air conditioning and cleaning room.

56, Several principles about airflow throttling , pressure reducing, channel expanding, noise absorbing and jet exhaust through ventage are adopted in the design.

57, Helical port also produces swirl by airflow interaction of valve gap and cylinder wall, so swirl number depends on helical line direction of relevant cylinder center.

58, We simulate engine performance in various operating conditions:in idle condition, it reduces the residual gas coefficient and increases airflow velocity, so that idle stability is improved.

59, The compressive effects of airflow are great on the aerodynamics at high speed's flight.

60, In the leeward slope, downslope wind and bypass-hill airflow affected the atmospheric vertical motion, which led the precipitation changes.
