Since oil phase materials, oxidizer, and water are important components of emulsion explosive, their influences on compression resistance performance of emulsion explosives in deep water was studied by using reusable experiment device to simulate the deep charging environment. The experimental results show that with the equivalent content of the oil phase material, the sequence of three oil phase types of emulsion explosives from good to bad in terms of compression resistance performance and explosion performance in deep water are composite wax, composite wax and machine oil, paraffin wax, vaseline and machine oil. With the equivalent content of oxidant, the type of oxidant species has quite small influence on compression resistance performance and explosion property. Within a certain range, water content has small influence on compression resistance performance, and explosion performance increases with the increasement of water content, while it significantly decreases with water content increasing to a certain amount.

We present a study of acoustic jets occurring in the vicinity of an orifice in a screen mounted at the end of a waveguide which conducts intense sound. The velocity field is measured by a cooling-power anemometer. We have used an impedance matching principle and demonstrated the ability to generate a strong acoustic jet and to create efficient resonant sound absorbers.
