Among the analysis methods, back-titration with Ca 〓 was adopted other than direct-titration or back-titration with NaOH. Because Ca 〓 method is carried out in acidic condition, in which the hydrolysis of ester-linkages could be neglected.

該法的分析測定是在酸性條件下進(jìn)行的人人人插人人干，多羧酸纖維素酯在酸性條件下基本不水解亚洲无码啪啪啪视频，可以忽略酯鍵存在對測定結(jié)果的影響。

The SERS of various concentration of Reactive Red, Acid Red, Acid Black, Direct sol orange and Calcon Carboxylic Acid adsorbed on silver colloid are studied by micro-Raman spectrometer. It has been found that the SERS intensity of absorbed molecules is mainly from the nearest molecule layer to the surface of silver colloid. That is, SERS has its single layer saturation effect. 2. The technique of direct deposition of silver colloid on a Kaolinite surface is first described.

The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.
