The results showed that compared with traditional fluorite and phosphorous slag, phosphorous slag composite mineralizer was effective on reducing amount of f-CaO in cement clinker and improving burnablity of raw meals, but the effect was still obvious when sintering temperature and sintering time were increasing. The analysis of XRD, SEM and petrographic structure showed that phosphorous slag composite mineralizer decreased viscosity of liquid, promotes the formation of Alite in clinker and improves crystal form and size of minerals.

结果表明，与传统的萤石和磷渣矿化剂相比，磷渣与萤石复合的矿化剂可有效降低水泥熟料中游离氧化钙的含量，改善生料的易烧性；在燃烧温度与时间增加的情况下，改善作用仍然明显；通过XRD、SEM与岩相结构分析表明，磷渣与萤石的复合矿化剂降低了液相的粘度，促进了A矿的生长，对矿物的结晶形态有改善作用，有利于晶体尺寸的生长发育。

矿床矿石硫化物硫同位素分析表明，早期矿化与晚期矿化具有不同的硫同位素特征：早期矿化硫化物的δ34S值(平均-4.31‰)明显小于晚期矿化硫化物的δ34S值(平均值为-1.83‰)。

AMELX, AMBN and ENAM are the major matrix proteins of enamel, and play different roles during different developing stages of tooth germs. AMELX may facilitate the growth of crystals in the early mineral stage, and act in the repairing of bone. AMBN may promote the mineralization of enamel matrix, and also keep the shape and size of crystals. ENAM may act in remineralization and promoting the growth of crystals.

AMELX、AMBN和ENAM为主要的釉质基质蛋白，在牙胚发育的不同阶段有不同的调节矿化的作用，AMELX在釉质矿化早期促进晶体生长，而其在骨中的表达则进一步表明其在骨修复中可能的作用；AMBN促进釉质基质矿化，并维持晶体形状、大小；ENAM促进和维持晶体生长，并与再矿化有关。

Cumulative NH4+-N is a good evaluating index of soil N-supplying not only for the first season crop, but also for two successive season crops. ND is more correct in revealing the potential mineralizable nitrogen when SON was regarded as mineralized N, although cumulative SON alone is not a good index for the potential of mineralizable nitrogen. And cumulative TSN could also be taken as an index for the potential mineralizable nitrogen to some extent.

淹水培养期间铵态氮累积量是评价可矿化氮的较好指标，不仅适宜于第一季作物，而且也适用于连续两季作物；SON累积量不能单独作为；SON累积量不能单独作为反映可矿化氮的指标，但用ND反映土壤可矿化氮潜势时，包括SON后更加准确；TSN在一定程度上能够反映土壤可矿化氮。

The results indicated that when initial NO3--N was not leached, soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation were closely related with raygrass nitrogen uptake, the correlation coefficients were 0.856 and 0.862, respectively, both reached at 1% significant level. When initial NO3--N was leached, it was no good relationship between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogrn uptake, the correlation coefficients were 0.410, 0.553, 0.492 and 0.419, respectively, indicating that the poor effects of mineralizable N on reflecting soil N capacity were influenced and disturbed by initial nitrate.

以包括土壤起始NO3--N盆栽试验植物吸氮量为参比，通气培养前CaCl2所淋洗起始NO3--N和起始矿质氮与5期黑麦草地上部氮素累积量密切相关，相关系数分别为0.856和0.862，达1%显著水平；与此相反，通气培养30周所矿化氮素、土壤起始矿质氮+通气培养30周矿化氮素、氮素矿化势(N0)及N0+起始矿质氮与5期黑麦草地上部氮素累积量间无显著相关关系，相关系数分别仅为0.410、0.553、0.492和0.419。

The psammoma body mineralization in meningioma is a common type of mineralizationThe analysis of the mineral composition may provide some support information in finding the reason of happening and developing of the diseaseThis paper focuses on the concentric layered structure mineralization in meningiomas, using mineralogical methods, such as HRSEM, ESEM, EDAX, EPMA, HRTEM, XRD and FTIR to systematically investigate the mineral composition, structure and shape of the minerals in psammoma bodies in meningiomasWe have devised a method for preparing the silicon wafer sheet which was used for the ESEM insitu observations and analysisIn this study, we first got the ESEM and HRTEM images of the initial mineralization phase of meningiomasThese images showed that in the early stage of psammoma body mineralization in meningiomas, many mineralized balls composed of octocaphosphate were precipitated on the collagen fibersThese balls continued to grow and aggregate, and were gradually hydrolyzed to become the dahlliteThe continued development of mineralization resulted in the mineralized collagen fibersThe study revealed that the concentric layered structure of the psammoma bodies in meningiomas is formed by the spiral arrangement of the mineralized collagen fibers on which the mineralized grains precipitated.

砂粒体矿化是脑膜瘤中常见的矿化类型，对其形成机理和矿物成分的分析可能会对肿瘤发生、发展的研究提供辅助信息。该研究选取人脑膜瘤中的砂粒体矿化作为研究对象，采用偏光显微镜、环境扫描电镜及能谱、X射线衍射仪、高分辨透射电镜和电子探针对样品的形貌、结构和成分进行测试分析，并以此为依据探讨脑膜瘤中砂粒体的形成机理。研究结果表明矿化的初期为沉淀在胶原纤维上的矿化小球，成分为磷酸八钙；矿化小球不断生长聚集，并逐步水解为碳羟磷灰石晶体，矿化的不断发展致使胶原纤维也发生矿化。砂粒体的同心层状构造是由螺旋状排列的矿化胶原纤维及沉淀在其上的矿化颗粒组成的集合体，而不是多数研究中所述：砂粒体是以坏死细胞残骸为中心由内至外的同心层沉淀。
