在分别用文字陈述、表格和图形三种外部表征方式集中呈现因果信息的条件下 ,用直接估计因果力大小的实验范式考察单一因果关系因果力估计的特点 ,检验概率对比模型 ,效力PC理论和 pCI规则。让 2 87名大学生被试估计不同化学药物影响动物基因变异的能力。结果发现 ,对单一因果关系因果力估计具有以下 4个特点 :⑴不对称性 :在预防原因条件下的因果力估计较多符合效力PC理论 ,而在产生原因条件下的因果力估计一般符合概率对比模型 ;⑵文字陈述、表格和图形三种信息外部表征方式 ,不影响产生原因条件下的因果力估计 ,但影响预防原因条件下的因果力估计。在预防原因条件下 ,与文字陈述和表格表征相比 ,图形表征会促使更多被试按效力PC理论来做因果力估计 ;⑶没有被试使用 pCI规则 ;⑷被试估计因果力所使用的规则存在明显的个体差异。

Earthquake Research in china 1998年第4期12卷 40-45页

作者： Wang Yucang, Yin Xiangchu, and Wang HaitaoLaboratory for Non-linear Mechanics of Continuous Media (LNM), Institute of Mechanics,chinese academy of sciences, beijing 100080, chinaLaboratory for Non-linear Mechanics of Continuous Media (LNM), Institute of Mechanics,chinese academy of sciences, beijing 100080, chinaCenter for Analysis and Prediction , CSB, beijing 100036, china

The load/unload experiments on rock failure under pressure have been carried out in Material Test system (MTS) in the Laboratory for Non-linear Mechanics of Continuous Media (LNM), Institute of Mechanics, chinese academy of sciences, and load/unload response ratio (LURR) values with strain as response (i.e. inverse elastic constant as response rate) have been obtained. The experimental results are in accordance with theoretical results and those in real earthquakes: LURR rises just before rock failure. So LURR can be used as the precursor of rock failure and earthquake prediction.

Four bacterial strains have been isolated for their ability to growth on dibenzothiophene (DBT), dibenzothiophene sulfone (DBTO2). The results show that different bacteria strains oxidize the DBT to different products through different pathways. R-6 and R-16 metabolize DBT to DBTO2 and HBP; they are identified as species of Bacillus brevis and Bacillus sphaericus. For long time storage, R-9 identified as Nocardia globerula oxidizes DBT to DBT-sulfone (DBTO2) and benzenamine n-phenyl. The optimum temperature and pH for growth of R-16 are 32℃ and 7.02 respectively. The pH of broth decreases during the processes.
