    摘要: Plant operating conditions 1, apparatus operating conditions 2 and environment conditions 3 are accumulated, combined and put together as a set of plant status variables 8 -through a monitor 6, while water chemistry information 4 is accumulated as another set of plant status variables 9. The set of status variables 8 is updated and the past data are accumulated in the set of status variables 9. Periodical inspection data 5 are also accumulated in the set of status variables 9 along with the water chemistry information 4. The set 9 is compressed and stored as a plant chart 11 such as a personal clinical chart. A status variable prediction 12 is performed in consideration of the personality of a plant. Both data of the sets 8 and 10 are compared with each other by comparison means 13. If both the data nearly coincide with each other, the plant is diagnosed to be normal and, if not, it is diagnosed to be abnormal. When the plant is diagnosed to be abnormal, an abnormal apparatus and an abnormal factor are identified.

    摘要: A diagnosis system having sensors for supervising a plant, signal processors for processing signals of the sensors, and a state quantity arithmetic operation unit. The state quantity arithmetic operation unit calculates a quantity of state expressing the environment of the plant on the basis of supervisory information inputted through the signal processors. A state quantity prediction unit predictively calculates a quantity of state after a predetermined time on the basis of the quantity of state, supervisory information and a time change of the quantity of state inputted through the state quantity arithmetic operation unit. A future event prediction unit predicts a future event on the basis of predicted information of the quantity of state inputted through the state quantity prediction unit. An image information processor converts the quantity of state given by the state quantity arithmetic operation unit into image information and indicates the image information on a display unit. An image information processor converts the predicted quantity of state after the predetermined time, given by the state quantity prediction unit, into image information and indicates the image information on a display unit. An image information processor converts the future event predicted by the future event prediction unit into image information and indicates the image information on a display unit.

    摘要: The composition of an alloy is inhomogeneous, so that the Fermi level of electrons in the surface of the alloy differs depending upon positions. It is accordingly considered that a part susceptible to corrosion and a part less susceptible thereto will coexist in the alloy. The corrosion rate of the alloy is indicated as the exponential function of a potential difference (.DELTA..PHI..sub.H) within an electric double layer. The potential difference remains unchanged as long as the Fermi level lies within the forbidden band of the electrons. However, in a range in which the Fermi level falls within the valence band of the electrons, the lowering thereof leads to the increase of the potential difference. Accordingly, a corrosion-resisting alloy is designed in accordance with the following guidelines: a) The electron energy level (Ev) of the valence band is low, b) an oxide film to be formed on the alloy is an n-type semiconductor, c) a band gap (Ec-Ev) is wide where Ec denotes the conduction band of the electrons, and d) a flatband potential (E.sub.f1) is low. Further, the operation of a plant and the evaluation of a corrosional damage can be based on such a theory.
