A new model for the life prediction of GH4133 under TMF conditions

Thermal mechanical cyclic strain tests were carried out under in-phase and out-of-phase conditions on a Nickel-base Superalloy GH4133 in the temperature range of 571-823℃. Based on analyzing the present models of TMF (thermal mechanical fatigue) life prediction, a new model for predicting nickel-base superalloy TMF lifetime was proposed.TMF life of superalloy GH4133 was calculated accurately based on the new model. Experimental TMF life has been compared with the calculatedresults and all results fall in the scatter band of 1.5. The calculating results show that the new model is not only simple, but also precise. This model will play great roles in life prediction of the metal materials and the engineering components subjected to non-isothermal service conditions.

Accurate forecasting of the undecided population in a public opinion poll

The problem of pollsters is addressed which is to forecast accurately the final answers of the undecided respondents to the primary question in a public opinion poll. The task is viewed as a pattern‐recognition problem of correlating the answers of the respondents to the peripheral questions in the survey with their primary answers. The underlying pattern is determined with a supervised artificial neural network that is trained using the peripheral answers of the decided respondents whose primary answers are also known. With peripheral answers as inputs, the trained network outputs the most probable primary response of an undecided respondent. For a poll conducted to determine the approval rating of the (former) Philippine president, J. E. Estrada in December 1999 and March 2000, the trained network predicted with a 95% success rate the direct responses of a test population that consists of 24.57% of the decided population who were excluded in the network training set. For the undecided population (22.67% of December respondents; 23.67% of March respondents), the network predicted a final response distribution that is consistent with the approval/disapproval ratio of the decided population.

硼酸对镍-镁合金电沉积和电化学性质的影响

该文报道了分别用0．05、0．10、0．15、0．33、0．50g／mL的硼酸进行电沉积镍-镁合金的实验。原子吸收光谱实验的结果表明，沉积相中包含不等量的镍和镁，电流效率也随硼酸量的不同而发生不同趋势的变化。从极化实验的结果，讨论了硼酸在电沉积中所起的作用是阻碍氢气的析出。在溶出伏安图中，能观察到5种不同强度的Mg2Ni峰，与XRD得到的结果相吻合。循环伏安测量结果证明镍-镁合金沉积薄膜电极具有良好的充／放电性能。
