A method for predicting the endurance life of pressure container includes such steps as inputting initial defect information and the 3D address information of node, calculating the area increment and expansion increment of crack, adding said expansion increment to original crack depth to obtain current crack depth, comparing it with the threshold stored in computer, and controlling the pressure container.

The invention relates to an antenna array, in particular to an antenna array of a hybrid radiator assembly. Its structure includes a metal radiator composed of a dipole radiator and a folded dipole radiator, and achieves the purpose of impedance matching by connecting the metal radiator in parallel; at the same time, it is used in a specific antenna operating frequency band The dipole radiator whose input impedance is capacitive is compensated for its capacitive effect by the folded dipole radiator whose input impedance is inductive in the aforementioned antenna operating frequency band, so that the antenna array of the hybrid radiator assembly of the present invention can operate on a specific antenna. Under the operating frequency band, it takes advantage of high efficiency and high directivity.
