In energy resource,power mechanics,agriculture,medicine,en-
vironment protection and other types of engineering,the study of multiphase
flow is very important.It is directly related to reasonable utilization of en-
ergy resources and better development of engineering technology.In recent
years,many scholars abroad and in our country have based their research
work on two-dimensional and three-dimensional mathematics and physics
simulation.However,it is diffcult to coincide with reality from such on
approach because of the assumptions of boundary conditions and initial
conditions.So the application range is small,the precision is low and the
actual results are condesirable.In this paper a multifunctional pulse laer holographic recorder is developed together with a helium-neon laser holog-
raphic image-representing system to collect and theat data.Then a description
of the authors' research work is made on the gas-mist multiphase flow
particle table distribution,the mass and density density distribution phase
as well as the vector field and typical trace of the marine gas turbine
intake-air multiphase flow also,analyses are made of the nonstationary mul-
tidimensional sticky vortex multiphase flow state and the relations of its para-
meters.Furthermore,practicas ways to expand the holographic record and
representation techniques in scientific and technological application are pro-
posed.Finally,the principles of reading multipulse,multiphase flow field
holographic record is described.
