atmosphere density
1.In the case of an N_2/O_2 mixed atmosphere,the FPD density and the oxygen precipitation density decrease with the increase of O_2 content.
2.Using Andersen micro-organisms sampling machine to collect airborne bacteria and airborne fungal particles in Shenyang atmosphere, and then observed and studied their density, density distribution and particles size distribution, and also the relation between them.
3.In/Ag,In/Al and Ti/Au were evaporated by using electronic beam evaporation,Van der Pauw,TLM,forked electrodes and n-ZnO/p-Si heterojunction by using microelectronic photo-etching,and thermal-annealing was performed at temperatures 200℃~500 ℃ in Ar atmosphere. The characteristics of I—V,resistance,carrier density,UV photoelectrical spectrum of PN junction and XPS were tested.
4.Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere .
5.The effects of atmospheric turoulence on the detection of the pilot frequency signal lf the 10.6μm CO_2 laser communication systems in atmosphere are studied in this paper. The amplitude probability density function of the received pilot frequency signal reflected by the corner-reflector under the disturbance of both laser power fluctuation and Gaussion white noise is derived and the caculating results are analysed.
6.THE RELATION BETWEEN OXYGEN GREEN LINE INTENSITY AND OXYGEN ATOM DENSITY IN THE UPPER ATMOSPHERE
7.And for as-rolled cathode foil,uniform distribution of intermetallic particles and high density of dislocations with cottrel atmosphere are required.
8.Hanford and Long first set up a virtual "box" filled with about 10 million carbon dioxide molecules floating about randomly, at the same density as the Martian atmosphere.
9.With the consideration of the stochastic effect of ocean surface temperature fluctuation (OSTF) during non - adiabatic heating of the atmosphere by the tropical ocean, an evolution epuation of Langevin type is established for the va -riation atmospheric heat. The steady - state solution of the random differential equation yields a heating potential function and probability density function.
10.Methods: Bone marrow-derived stem cells of a five-month-old New Zealand White rabbit were isolated with a density gradient and culture-expanded in DMEM supplemented with 15% FBS at 37 , 5%CO2 atmosphere incubator.
