An accumulator is provided in an oil circuit of the pressure supply device and has a gas chamber for storing the pressure generated by the oil pump. A gas pressure judgment unit judges a soundness on the gas pressure of the gas chamber of the accumulator. A pitch movement judgment unit judges whether the pitch movement is performed soundly by the oil pressure accumulated in the accumulator if the gas pressure judgment unit judges that the gas pressure is sound. A start judgment unit judges a start condition to start the gas pressure judgment unit every predetermined period or when a start switch is operated.

The invention provides a large-radius chamfer sleeper used for controlling concrete cracks of a ballastless track and a construction method. In the large-radius chamfer sleeper, (1), large-radius chamfers are used for the corners of the sleeper, the chamfer part is equivalent to a quarter of a circular platform, and the radius of the top of the circular platform is generally not less than 80mm; (2), crack-proof steel bars are arranged on the periphery of the sleeper, wherein the crack-proof steel bars can be arranged to form a closed loop along the outer side of the sleeper or to form loops only in certain ranges of the ends of the sleeper, and ribbed steel bars with nominal diameters being 14mm-20mm are utilized as the crack-proof steel bars; (3), when the grade of the carbonation environment effect is T2, the thicknesses of the protection layers of the crack-proof steel bars are 35mm, and when the grade of the carbonation environment effect is T3, the clear spacings between the crack-proof steel bars and the sleeper are 20mm-30mm; (4), during the construction of the large-radius chamfer sleeper, fixing position accuracy in the whole track bed and soundness of the crack-proof steel bars need to be guaranteed, and meanwhile, the crack-proof steel bars need to be separated from other steel bars.

To enable efficient abduction even for observations that are faulty or inadequately modeled, a relaxed abduction problem is proposed in order to explain the largest possible part of the observations with as few assumptions as possible. On the basis of two preference orders over a subset of observations and a subset of assumptions, tuples can therefore be determined such that the theory, together with the subset of assumptions, explains the subset of observations. The formulation as a multi-criteria optimization problem eliminates the need to offset assumptions made and explained observations against one another. Due to the technical soundness of the approach, specific properties of the set of results (such as correctness, completeness etc.), can be checked, which is particularly advantageous in safety-critical applications. The complexity of the problem-solving process can be influenced and therefore flexibly adapted in terms of domain requirements through the selection of the underlying representation language and preference relations. The invention can be applied to any technical system, e.g. plants or power stations.

The invention relates to a method for monitoring the soundness of helicopters comprising the determination of the severity of a plurality of flight missions of a plurality of helicopters, comprising a step for acquiring and storing flight data from helicopter flight missions, and a step for acquiring and storing maintenance data from the plurality of helicopters. The method is characterised in that said determination comprises a mission-type construction step, comprising a sub-step for constructing descriptors, a sub-step for partitioning the descriptors and a sub-step for allocating a mission type to each flight by associating the descriptor of said flight and a sub-set, in which this descriptor is found, and a step for interpreting the severity of the mission types, comprising a sub-step for estimating the severity models, and a sub-step for associating a severity model with each mission type determined in the mission type construction step.

The invention discloses a compound heat preservation die plate and a concrete one-off construction outer wall heat preservation system and a construction technology thereof. The invention is characterized in that the compound heat preservation die plate is used for replacing simultaneous construction of the die plate and concrete pouring, so that a heat preservation layer and a building mainbody can be completed together; the compound heat preservation die plate can both act as a heat preservation plate and a die plate, thus saving outer wall die plates in large quantities, greatly shorteningconstruction period and cost, fundamentally resolving the question of connection soundness between the heat preservation layer and the building mainbody, addressing the question of flatness and verticality of the heat preservation layer and ensuring construction quality.

When a manager uses an input device to input the inspected states of the degrees of soundness of a plurality of objects, a data receiving unit receives them as inspection data. A deterioration characteristic calculating unit calculates the average value of the deterioration characteristics of the objects based on data related to the degrees of soundness of the plurality of objects that is received by the data receiving unit. A heterogeneous parameter calculating unit calculates a heterogeneous parameter for each heterogeneous factor that cannot be observed or is difficult to observe, and causes a variation in the deterioration characteristics. A benchmarking unit evaluates the influence of the heterogeneous factors on the deterioration characteristics based on the heterogeneous parameters, and an output unit outputs the evaluation result.

A test method for soundness of a secondary barrier in a liquefied gas tank includes the steps of: (A) observing an integrated automation system; (B) performing a first differential pressure test when abnormality is observed through the observation in the step (A); and (C) performing, when a pressure in an insulation space and a pressure in an inter-barrier space are not equal to each other or pressure reversal occurs after the pressures become equal to each other as a result of the first differential pressure test in the step (B), a second differential pressure test. The test method further includes: (D) performing, when the pressure in the insulation space and the pressure in the inter-barrier space are equal to each other as a result of the second differential pressure test in the step (C), a third differential pressure test.
