X-rays and other forms of radiation were known to kill cells and these were aimed at lymph glands near and distant, on sites of secondary cancer spread in bone and lung and brain.

The test showed that in the region dominated by sub tropical high, short wave radiation was the main cause of the SST increase, surface warm water convergence played a secondary role.

In the active structural acoustic control based on radiation modes, the cancellation of the dominant radiation modes and determination of the arrangement of secondary forces are of virtual important.
