1.For abnormally high-pressure gas reservoirs,a non-Darcy flowing equation of gas well is expressed as pe2-pwf2=Aqg+Bqg2+Cqg3,whose A,B and C are hard to be calculated from the back-pressure testing data and so relevant professional software is necessary.
3.A wind-tunnel testing of a streamline traced hypersonic Busemann inlet,with a designed Mach 5.3 and shrinkage ratio CR=5,was conducted at Mach 3.85 to study its starting and overall performance as well as back-pressure capability below Mach 5.3 conditions.
4.Under the testing and tracing back system, pigs are tattooed with consignment-specific, five-digit numerals identifying the farm of origin and are tested for clenbuterol on admission to slaughterhouses.
