查询词典 density

Under the conditions of stir speeds 400 r·min~(-1) and distance between anode and cathode 1 mm, by using the orthogonal design, the optimum technological conditions were found that the current density was 0.3 A·cm~(-2), initial NaOH concentration in catholyte was 50 g·L~(-1), reaction times of two steps were all theoretical electrochemical reaction times. In the first electrosynthesis, initial Na_2CrO_4 concentration in anolyte was 650 g·L~(-1), and reaction temperature was 80℃. In the second electrosynthesis, initial Na_2Cr_2O_7 concentration in anolyte was 700 g·L~(-1), and reaction temperature was 85℃.

This conclusion, combined with the data obtained from the short-lived Hf-W and Sm-N d isotopic systematics, suggests that the Moon was initially accreted at 4.5 Ga, followed by development of the global lunar magma ocean. The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However, the mafic minerals, coevally crystallized with the plagioclase, sank to the base of the LMO due to their high density, and made up the main part of the lunar mantle, which served as the source during later mare basaltic magmatism.

根据这一年代资料，结合对月岩样品进行的短半衰期Hf-W与Sm-Nd同位素体系的研究结果，认为月球大致形成于45亿年，其后开始由岩浆海导致的内部核－幔－壳的分异，岩浆结晶的低密度斜长岩构成最初的月壳，而密度大的岩石构成月幔，而此月幔则成为后来月海玄武岩的主要岩浆源区。
