Taking into account the effects that the components of tension stresses couple with components of torsion stresses when off-axis loads are applied to orthotropic materials, Hill s yield criterion for plastically orthotropic solids is modified by adding an invariant that is composed of the product item of quadratic components of the deviatoric stress tensor, and a new yield criterion is put forward in terms of the characteristics of the face-centered cubic (FCC) single-crystal material. The correlation of prediction and experiments is very good, and the new criterion is used to predict the yield stresses of an internal single-crystal, Nickel-based superalloy, DD3, which is more accurate than that of Hill s at 760?C. Equivalent stress and strain that adapt to the new criterion are defined. Thinking of the yield function as a plastic potential function from the associated flow rule, the elastic plastic constitutive model for the FCC single-crystal material is constructed, and the corresponding elastic plastic matrix is educed. The new yield criterion and its equivalent stress and strain will be reduced to Von Mises yield criterion and corresponding equivalent stress and strain for isotropic materials.

从催化裂化反应机理出发,提出了两个反应区的概念,设计了具有两个反应区的串联提升管反应器并形成相应的工程技术,在此基础上进行了中小型探索试验和工业试验。1.4 Mt/a多产异构烷烃的催化裂化装置试验标定结果表明:与现有的催化裂化工艺相比,该工艺不仅优化了产物分布,干气和油浆产率分别下降了0.41%和0.99%,液体收率增加了1.17%,而且所生产的汽油烯烃含量下降约14.1%,异构烷烃增加约为12.9%,硫的质量分数ω(s)下降26.5%,诱导期增加,汽油的RON下降而MON增加,总的抗爆指数略有下降。

Spent FCC catalyst with lanthanum is proposed as a novel P-removal adsorbent. The spent FCC catalyst exhibits 99% adsorption efficiency for low P-concentration wastewater (C0 <5.0 mg/L). High affinity, endothermic reaction and fast sorption kinetics are achieved. The phosphate is adsorbed in the form of LaPO4 and KH2PO4.
