矿化作用

The gold deposit is closely associated with the feldspathic quartz gray-wacke of the Zhuanqiangwan Formation of the Furongxi Group and the pebble-bearing feldspathic quartz gray-wacke of the Sinian Changtan Formation.

芙蓉溪群砖墙湾组长石石英杂砂岩和震旦系长滩组含砾长石石英杂砂岩均具明显的控金作用。砂岩层往往大面积发生矿化蚀变，矿体严格受砂岩层控制。

But foliar N of the remaining mass still decreased with decreasing mass, mainly due to mineralization.

但氮剩余量仍随重量的减少而下降，可能由於氮只发生矿质化作用。

Firstly it plays the fine separation role and maintains the separation selectivity, secondly the role of countercurrent-collision mineralization and separation and prerecovering the material with good floatability (the gangue of column flotation as middlings will undergo further separation and recovering).

它首先要发挥精选作用并确保整个设备的分选选择性；然后才是逆流碰撞矿化与分选，预先回收可浮性好的物料（其尾矿还要进一步分选回收）。

The results show that the2 0～ 40 cm and40～ 60 cm layers for the red loessial soil and2 0～ 40 cm layer for the red loessial soil had a large amount of easily mineralizable nitrogen besides the0～ 2 0 cm layer, but the easily mineralizable nitrogen was little...

总体上看，红油土中氮素的矿化和硝化作用强于红垆土。铵态氮肥在粘粒含量少、有机质含量高土层中的迅速减少主要归咎于硝化，而在粘粒含量多、有机质含量少的土层，主要取决于矿物固定

In the presence of O〓, peroxyl radicals formed under neutral condition are either directly oxidized to non-aromatic acids, or forms aromatic intermediates, which are further oxidized to non-aromatic acids; peroxyl radicals formed under alkaline conditions are directly oxidized to non-aromatic acids.

有氧状态下的羟基自由基氧化体系中，过氧自由基在氧气的催化作用下既可开环形成有机酸，也可形成4-氯邻苯二酚和对苯二酚，进而氧化开环成有机酸，并最终矿化；碱性条件下的过氧自由基则直接开环降解。

Hydroxypropylmethylcellulose which possesses weak polarity groups, like polyhydroxy groups and ether groups, will transform to hydrogel when temperature increases.

纤维素衍生物羟丙基甲基纤维素分子中含有大量的羟基和醚键，其水溶液在升温情况下可以发生凝胶转变，是一种新型的有机模板，本文对其作用下特别是凝胶状态下的矿化进行了探讨。

Studying the influence of milk protein pel-licles on demineralization and remineralization of tooth surface can further ensure the mechanisms of protection against dental caries of milk .

研究牛奶蛋白膜对牙表面矿化的影响，对于进一步理解牛奶的防龋作用具有重要意义。

It focuses on stopping the disease process and patient-friendly surgical intervention only when required. This article describes the application of MID in geriatric caries manage-ment: Assessment of the risk of caries; early detection; external and internal remineralization.

本文主要阐述了MID理念在老年龋病预防中的应用，主要内容包括患龋风险评估、龋病早期诊断、促进牙体外部和窝洞内部的再矿化，体现了MID在老年龋病早期诊断、早期治疗以及控制龋病进程中的重要作用。
