Abstract: Provided in the present application are a trajectory query method and apparatus. The trajectory query method comprises: acquiring a trajectory query request, which comprises query information of a plurality of types; according to query information of a service type in the query information of the plurality of types, determining a query range of metadata used as a digest of a trajectory, then determining a plurality of pieces of candidate metadata that are within the query range, and determining, from the plurality of pieces of candidate metadata, target metadata that matches the query information of the plurality of types; and acquiring a target trajectory according to the target metadata. By means of the present application, the trajectory query speed can be increased.

Abstract: A fat formulation can include triacylglycerides that can be made of glycerol esterified with straight-chain saturated fatty acids, where a solid fat content as a function of temperature of the triacylglycerides differs from a solid fat content of butterfat by at most 0.1 at any temperature between 0° C. and 40° C. A fat formulation can include triglycerides that include straight-chain, saturated fatty acids selected from a distribution of fatty acids with between 4 and 24 carbon atoms, where the distribution comprises a non-monotonic change in relative fatty acid content between the fatty acids with between 4 and 24 carbon atoms.

Abstract: A bubble detection device and a sample processing instrument are provided. The bubble detection device includes a body, a cover and a detection circuit board. The body includes a bottom wall and first and second side walls respectively extending from two sides of the bottom wall. The bottom, first and second side walls define a groove for accommodating a sample pipe of a sample processing instrument, and first and second holes are respectively provided in the first and second side walls to allow light from a light source to pass through the sample pipe. The cover includes a top portion for covering the groove and first and second side portions attached to the body. The detection circuit board includes the light source and a photoelectric sensor and is attached to the body such that they are aligned with the first and second holes respectively to sense intensity of the light passing through the sample pipe. The sample processing instrument includes the bubble detection device.
