An analysis apparatus includes a detector and a determination unit. The detector detects, for a target particle, a direction of a surface that is in proximity to the target particle. The determination unit determines the target particle to be a surface particle in a case where the number of other particles within a predetermined region extending in the direction of the surface is smaller than a threshold.

An apparatus for checking a need for maintenance of a viscometer measuring consistency of suspension comprises a rigid rod and an elongated cavity in a measuring arm of the viscometer. The rigid rod is matched with the cavity for the rod to be movable in the cavity. The cavity is configured to become mismatched with respect to the rod in response to a bending of the measuring arm, the mismatch indicating a need for maintenance of the viscometer.

Methods for evaluating whether there is a probability that coal will reduce the strength of coke using an apparatus including a stirrer. A degree of entanglement (a−b)/a represented by the heights a and b, or the height a only, is used as an evaluation index for coal, where a height of the semicoke on an inner wall of the container is represented by b, and a height of the semicoke on the stirrer is represented by a. Semicoke formed from heated coal is formed in the container using the degree of entanglement as an evaluation index.

Methods for determining the gelation period of a gel solution are provided. The methods provided include introducing a first inert ball, or first inert hollow ball comprising a polymer solution, into a gel solution container containing a gel solution where upon the first inert ball, or inert hollow ball, reaching a bottom of the gel solution container, at least one subsequent inert ball, or inert hollow ball, is introduced sequentially into the gel solution container until the at least one subsequent inert ball, or inert hollow ball remains fixed in place prior to reaching the bottom of the gel solution container. Methods also include determining the gelation time of the gel solution based on a sum of distances traveled by the first inert ball, or inert hollow ball, and at least one subsequent inert ball, or inert hollow ball.
