Annular syphilid is an uncommon presentation of secondary syphilis, previously seen almost exclusively in black.

Hypanthium obconic, campanulate, or cyathiform, caducous at fruiting time, only annular base remained.

According to the syntaxis skill of shock wave and the theory of effective charge,the annular conical booster pellet structure is designed.

An annular cavity placed around the anode of arcjet was designed to form a regenerative cooling channel on the base of an arc jet.

Numerical simulations of laminar flow separation and reattachment occurred in an annular backstep passage are performed by the SIMPLER algorithm.

A new multiflow model of a pressurized spout fluid bed with a draft tube has been developed to investigate the voidage and the velocities of particle and gas in spout and annular region.

The paper introduces a new type slim - hole MWD tool, which is capable of accurately measuring downhole annular pressure and pressure effect caused by swabbing and waveness.
