With the two English versions of the ancient code of science and technology ＂Exploitation of the Works of Nature＂, by introducing the concept of the semantic domain, the author divides the biased errors in the translation of the English versions of ＂Exploitation of the Works of Nature＂ into three categories of the migration of the semantic domain, the reduction of the semantic domain and the expansion of the semantic domain, which are illustrated respectively. We find that the boundaries of the semantic domains of the words in the scientific and technological codes and books are usually clear. Therefore, when selecting the translation words, we must choose the foreign words with the same semantic field, to prevent the unnecessary translation errors, which will affect the overseas dissemination of the scientific and technological classics.展开更多

The three class computer communication system that integrates with measurement and alarm and management works reliably and uses conveniently, especially to thesystem of parameter detecting and alarm in mine, which is adapted to measure dispersedly and manage intensively.展开更多

Combinatorial materials chip technology, featuring high-throughput synthesis and characterization, is able to determine the phase diagram of an entire composition spread of a binary or ternary system at a single temperature on one materials library, which, though significantly increasing efficiency, still requires many libraries processed at a series of temperatures in order to complete a phase diagram. In this paper, we propose a "one-chip method" to construct a complete phase diagram by individually synthesizing each pixel step by step with a progressive pulse of energy to heat at different temperatures while monitoring the phase evolution on the pixel in situ in real time. Repeating this process pixel by pixel throughout the whole chip allows the entire binary or ternary phase diagram to be mapped on one chip in a single experiment. The feasibility of this methodology is demonstrated in a study of a Ge-Sb-Te ternary alloy system, on which the amorphouscrystalline phase boundary is determined.展开更多
