    • Pulse shape analysis determines if two radiations are in coincidence. A transducer is provided that, when it absorbs the first radiation produces an output pulse that is characterized by a shorter time constant and whose area is nominally proportional to the energy of the absorbed first radiation and, when it absorbs the second radiation produces an output pulse that is characterized by a longer time constant and whose area is nominally proportional to the energy of the absorbed second radiation. When radiation is absorbed, the output pulse is detected and two integrals are formed, the first over a time period representative of the first time constant and the second over a time period representative of the second time constant. The values of the two integrals are examined to determine whether the first radiation, the second radiation, or both were absorbed in the transducer, the latter condition defining a coincident event.
    • 脉冲形状分析确定两个辐射是否一致。 提供了一种换能器,当其吸收第一辐射时产生一个输出脉冲,该输出脉冲的特征在于较短的时间常数,其面积名义上与吸收的第一辐射的能量成比例,并且当其吸收第二辐射时产生输出脉冲 其特征在于较长的时间常数,其面积名义上与吸收的第二辐射的能量成比例。 当辐射被吸收时,检测输出脉冲,并且形成两个积分,第一个时间段代表第一时间常数,第二个在代表第二时间常数的时间段内。 检查两个积分的值以确定第一辐射,第二辐射或两者是否在换能器中被吸收,后一个条件限定重合事件。

    • A controlled shot-peening of blisk blades (1) uses a stream of spherical shot-peening medium transported by compressed air or water. The shot is driven essentially at a right angle onto each blisk blade individually, actually simultaneously on both blade sides, and with identical impact intensity and immediately opposite on both sides in several side-by-side processing paths extending over the entire blade surface. A dual-nozzle unit (6) is linearly moveable in two directions normal to each other, and swivellable about an X and a Y axis. The unit (6) includes two preferably rectangular, essentially parallel arranged, shot-peening nozzles (7), whose spacing is settable in accordance with the blade profile, each of which has a nozzle opening situated at the same level and facing the pressure or the suction side of the respective blisk blade, and featuring identical distance to the respective blade surface during shot-peening.
