盐沉积物

In this paper, the electroplating of bright Zn-Ni alloy process was studied, the effect of (1-hydroxy ethylidene diphosphonate acid coordinating agent, chloride content, [Zn2+]/[Ni2+] mole ratio, cathode current density, temperature, a class of aldehyde compound (abbreviated as ZNP additive agent) and supplementary coordinating agent on Ni content, and brightness of plating layer was discussed, the physical phase of alloy plating layer and stability of plating solution were determined.

研究了用有机多膦酸盐作络合剂，ZNP作添加剂电镀光亮锌镍合金，探讨了络合剂、氯化物含量、[Zn2+]/[Ni2+]比、阳极电流密度、温度、辅助络合剂对合金中镍含量的影响，测定了合金镀层中物相组成及镀液稳定性，通过筛选得出最佳最镀光亮锌镍合金的镀液组成及工艺条件，并讨论了锌镍合金的异常共沉积机理。

Sulfur isotope of franeolite indicate that sulfur isotope value of phos phate concretion is larger than that of evaporite sulfate, there is little doubt that sulfur isotope fraetionation happens during phosphorite diagenesis, heav ier sulfur is laid in sediments because of formation of H〓S.

磷结核的稳定S同位素测试表明：其值大于同时代海水蒸发盐的值，这是由于在成岩作用过程中发生了S同位素分馏，生成H〓S，从而使沉积物中富集〓S。

Based on the XRD data of the field samples, the following hydrothermal sedimentation indicators are discovered: silicious sediment, rock salt, gypsum and natural sulphur.

经野外取样和XRD测试技术，在即墨温泉盆地发现硅质沉淀物、盐华、石膏、自然硫等温泉热水沉积指示物。
