portion of the ordinate and the abscissa for each operation mode condition as described above the reason why items are sorted as u201c small matrix 1 1 u201d and u201c small matrix 1 2 u201d is based on the following matter for example in u201c vibration resulting from scattering and come off of rotating components generates as unbalanced vibration fluctuation u201d factor 2 if the vibration generates during the acceleration and deceleration of rotational speed vibration fluctuation at the dangerous speed of the turbine rotor rotary shaft remarkably appears on the other hand if the above vibration generates during load element 1 sudden vibration fluctuation appears thus the difference occurs between phenomenon events depending on operation mode conditions of the controlled equipment the vibration diagnosis in the diagnosis engine section 23 is summarized as shown in fig4 in the following manner that is as seen from each diagnosis matrix of fig5 the same technical matters as the query matter displayed by the vibration mode interactive query section 20 are displayed on the abscissa column in the ordinate row prepared answers are selected and point for weighing is given the highest point of the given points is picked up and based on the picked up highest point answering rate matching rate and probability of the vibration factor obtained from vibration features and operation process are calculated the calculated result thus obtained is summarized for duvh each query as shown in fig4 this is because of preventing biased analysis when specifying the vibration factor fig4 shows one example of collecting the diagnosis result in the diagnosis engine section 23 as matrix in.
