Disclosed are a novel transition metal compound represented by the following general formula, a catalyst component for olefin polymerization comprising same, a catalyst for olefin polymerization comprising said catalyst component, and a process for the preparation of an a-olefin polymer: 1where the definition of formula is described in the specification. At least one first border includes a first segment and a second segment, where one end of the first segment is connected to one end of the second border, and one end of the second segment is connected to one end of the other second border. The cuvettes can thus be stored as plates in a feed magazine of an analytical device. Since an image signal transmittedreceived between the display apparatus and the host has a coded format, a chip size of the display apparatus and an information processing system with the same is reduced and an amount of transmission data is also reduced. The disclosure further relates to methods for production of these immunogens and compositions and their use in medicine.
