摘　　要：为了获得发动机燃料喷射雾化特性,运用PDPA和激光全息术对喷嘴的燃料雾化粒子场进行测量。简要介绍了两种测量方法的原理和应用条件,对两种方法的测量结果进行了对比,验证了激光全息术测量结果的精度。最后在风洞实验条件下进行了喷射燃料粒子场测量。The atomization behavior of the fuel injector in engine was obtained by the measurement of the fuel particle field by using phase doppler particle anemometer（PDPA） and laser holography technique.The principles and condition of two measurement methods were introduced in this paper.The results from laser holography measurement were given and compared with PDPA technique,which shown that the laser holography method is precise.Moreover,the particle field of fuel injector was measured in wind tunnel.
