摘要： Polymer aggregates and molecular polymers are written as computable numbers, resulting in a unity between cells and universal Turing machines with the Entscheidungsproblem. However, whether the Entscheidungsproblem of cells really exists remains elusive. Alan Turing found universal Turing machines read only computable numbers written by humans who further differentiate transcendental numbers from the set of computable numbers by Georg Cantor’s diagonal process. It follows that the decidability of the Entscheidungsproblem derived from humans eliminates the independence of computable numbers from each other and enables computable numbers to be fused with each other into the set of computable numbers, with the result that humans are endowed with a capacity to read of the fusion of computable numbers with each other into the set of computable numbers by humans to read the set of computable numbers bearing computable numbers by being endowed with a capacity to write computable numbers. Accordingly, it is shown here how humans are invited to write cell backbones as complex numbers read by artificial intelligence machines emulated by cells by writing polyribonucleotides as computable numbers read by universal Turing machines emulated by extracellular ribosomes to extend Georg Cantor’s continuum hypothesis by being invited to extend Alan Turing’s work on the Entscheidungsproblem, resulting in a unity between cells and artificial intelligence machines without the Entscheidungsproblem.

摘要： Ferritic/martensitic (F/M) steels have been widely used as structural material for thermal and nuclear power plants. However, it is susceptible to intergranular damage in service conditions, which is expected to be critical issues. In order to improve the intergranular damage resistance of F/M steel, thermomechanical process (TMP) was employed to achieve a grain boundary engineering (GBE) microstructure in a kind of F/M steel P92 in this study. TMP, including cold rolling to 6%, 9%, and 12% thickness reduction, respectively, followed by austenization at 1323 K for 40 min plus tempering at 1053 K for 45 min, were applied on as-received (AR) P92 steel. Both prior austenite grain (PAG) size, prior austenite grain boundary character distribution (GBCD), and the connectivity of prior austenite grain boundaries (PAGBs) were investigated. Compared with AR specimen, the PAG size does not change significantly. The fraction of coincident site lattice boundaries (CSLBs, 3 ≤ Σ ≤ 29) and Σ3n boundaries along PAGBs decreases with increasing reduction ratio due to the recrystallization fraction increases with increasing reduction ratio. The PAGBs connectivity of the 6%-deformed specimen deteriorates compared with that of AR specimen slightly. Moreover, the potentiodynamic polarization studies revealed that the intergranular damage resistance of studied steel could be improved by enhancing the fraction of CSLBs along PAGBs, indicating that TMP, involving low deformation, could enhance the intergranular damage resistance.
