A color vision characteristic detection apparatus has a storage section, a generation section, and a presenting section. The storage section stores a basic color chart containing portions colored in colors different from each other. The generation section performs a predetermined conversion processing with respect to the basic color chart to generate an adjusted color chart for one color vision characteristic type so that it is difficult for a person who has a visual characteristic of the one color vision characteristic type to distinguish the adjusted color chart from the basic color chart. The presenting section presents the basic color chart and the adjusted color chart to a user.

A method for a cation-exchange resin wherein a strongly acidic cation-exchange resin is contacted with an aqueous eluting solution and the polystyrenesulfonic acid being eluted from this resin is measured, which comprises setting a plurality of molecular weight ranges in the molecular weight distribution of the polystyrenesulfonic acid eluted, and evaluating the performance capability of the cation-exchange resin based on the correspondence relationship of each molecular weight range with the amount eluted in said each molecular weight range. The evaluation method allows on-target and precise evaluation of the performance capability of a cation-exchange resin being independent of the structure of a base resin and the circumstance under which it is used, which leads to the determination of the optimum time for the exchange of a resin in a water treatment system using a cation-exchange resin, and thus to the extension of exchange of a resin and the reduction of an operation cost for the system.

A high-sensitivity measuring instrument comprising at least two sensors for detecting the same characteristics by touching a substance being measured with a specified time difference, wherein the between detection signals taken out simultaneously from respective sensors is determined, the difference between characteristic values upon elapsing the specified time difference is determined from the difference between detection signals, a reference time of measurement and a reference characteristic value at that time are preset, a time axis having a time pitch of a specified time difference is set, and a measurement value is obtained at a point in time elapsing an arbitrary time pitch from the reference time. Objective measurement characteristics can be detected by the measuring instrument not in the form of difference or variation but as an absolute value with high accuracy and sensitivity.

Oxygen is mixed with heater drain water of power plant which contains fine particles of iron oxides such that the concentration of the dissolved oxygen in the heater drain water after the mixing of oxygen is in a range from 1 &mgr;g/liter to 20 &mgr;g/liter. The obtained heater drain water after oxygen mixing is filtered through a filter such as a hollow fiber filter to remove fine particles of iron oxides.
