摘要： A continuous process for the preparation of copolycarbonate resins has great advantages in preparing molding materials of intricate structure or of thin-wall: the molding process may be conducted easily at a relatively low temperature; the copolycarbonate has excellent impact strength especially at a low temperature; and they have excellent melt flow, i.e. 2 to 3 times of the conventional polycarbonates. The present invention is a new polycondensation process which is carried out sequentially by using serially connected tube-type reactors to simplify the process; and enhancing the rate of reaction for an incorporation of comonomer into the polymer backbone resulting from varying Reynols Number, Linear Viscosity and Weber Number.

摘要： Disclosed herein are an apparatus and method for measuring quality of an image received via a communication network. The apparatus includes an interface unit, a codec unit, a test image detection unit, and a Mean Opinion Score (MOS) measurement unit. The interface unit receives an image, including a start synchronization image and a test image via a communication network. The codec unit decodes the received image into a color signal. The test image detection unit detects any one value of brightness, saturation and hue information of the color signal input from the codec unit, calculates an average value for each frame, and detects the test image from the received image based on the calculated average value. The MOS measurement unit synchronizes the test image with a corresponding reference image, compares the quality of the test image with the quality of the reference image, calculates an MOS value based on the results of the comparison, and outputs the MOS value.
