Subjects in China, Japan, and the United States reported probability judgments. In Study 1, Chinese and American subjects indicated degrees of certainty about their answers to general-knowledge questions with discrete alternatives, e.g., whether potatoes grow better in warm or in cool climates. In Study 2, Japanese subjects made similar discrete-alternative assessments. In Study 3, subjects in China and the United States reported probability distribution judgments for various quantities, e.g., the maximum temperature on a specified day. Judgment accuracy was evaluated overall and with respect to several underlying accuracy dimensions. The overall quality of discretealternative judgments was indistinguishable among the subjects from the three countries. The accuracy component patterns of the Japanese and American subjects were essentially the same. However, the Chinese subjects achieved the common overall accuracy level very differently. On some accuracy dimensions, e.g., calibration, the American and Japanese subjects' judgments were superior. On others, e.g., discrimination, the assessments of the Chinese subjects excelled. Results for quantity judgments were similar to those for disCrete alternative judgments, although there were notable differences. Potential explanations and implications are discussed. 8 1x39 Academic RCSS, I~C.

ZnO-Fe2O3 catalysts were prepared by thermal decomposition of layered double hydroxides containing zinc and iron within the brucite-like layers and carbonate as the interlayer anion, then the hydrotalcite precursor and mixed oxides were characterized by ICP, XRD and N2 adsorption/desorption techniques. XRD patterns showed that both ZnO and ZnFe2O4 phases appeared for the mixed oxides and their proportion and crystalline degrees depended on the heat treatment temperature. Furthermore, these mixed oxides were tested for the diethyl carbonate (DEC) synthesis from ethyl carbamate and ethanol. More important, the DEC yield could reach to about 32.3% in the bacth reactor under the optimal reactions.

The implicit parametric method was briefly discussed in this paper. An implicit parametric 3D solid model and a finite element (FE) model of a body-in-white (BIW) were built up by this method. Low order natural vibration frequencies and modes, bending and torsional stiffness of the BIW were analyzed by FE calculation. A good agreement was acquired by comparing the prediction results with the test values. Results indicated that the implicit parametric model of the BIW established could be used for design and development of the BIW in concept design stage of the BIW.
