An optical detection apparatus which is capable of measuring a sample is provided. The optical detection apparatus includes a plurality of light emission units, a light receiving unit, a driving unit, and an analyzing unit. Each of the light emission units is capable of emitting a light beam. The light receiving unit is capable of receiving the light beam passing through the sample and is capable of converting the received light beam to an electrical signal. The driving unit is capable of changing the relative position of the light emission units and the sample. The analyzing unit is electrically connected to the light receiving unit and is capable of measuring a property of the sample by using the electrical signal. A number of the light receiving unit is less than a number of the light emission units. An optical measurement system including the optical detection apparatus is also provided.

A multi metal base thermal resistance alloy and a mold with the multi metal base thermal resistance alloy layer are provided. The weight percent of each element in this alloy is less than 45%. The structure of the alloy is an amorphous structure and the phonon thermal conductivity of the amorphous structure is intrinsically low. Therefore, the alloy is a metal material with low thermal conductivity coefficient and high thermal stability, which can increase the heat retaining property of the die casting mold, enhance the forming yield and stability of a metal sheet with a low fusion point, and is suitable to be used as a thermal-resistance coating material on die casting molds.
