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。

Results Fluoridated milk had significant effects of remineralization,anti-deminer alization and anti-caries.

结果 氟化牛奶有明显的再矿化、抗酸脱矿及抗龋作用，而氟水有一定的抗酸脱矿及抗龋作用，无再矿化作用。

CPP-ACP has the ability of promoting remineralization of enamel artificial white spot lesions which can be enhanced by fluorid.The remineralization ability depends on the concentration of calcium phosphate stabilized by CPP-ACP.

CPP-ACP溶液可于体外使脱矿牙釉质发生再矿化，且矿化作用可被氟加强；再矿化作用与CPP稳定的钙磷浓度呈剂量-效应关系。

The results of XRD indicated that the addition of lanthanum in skutterudite could enhance the formation of skutterudite during the synthesis process. The content of skutterudite increases with the increase of the filling fraction in 〓. The lattice parameter of filled skutterudite increases with the increase of lanthanum filling fraction. It is caused by the deformation of Sb〓 ring arising from the "rattling"of the filling atoms in the voids in skutterudite.

对不同填充率方钴矿La〓Fe〓CoSb〓材料的XRD研究发现，镧元素的引入可以促进方钴矿相的合成，相同条件下合成的方钴矿的纯度随镧填充率的增大而提高，材料的晶胞参数随镧填充率的提高而增大，这是填充原子在方钴矿晶体的的孔隙内震颤和晶胞内Sb〓四边形发生扭曲变形所致。

Synthesis and Thermoelectric Properties of Nano-Skutterudite Compounds by Chemical Methods;2. Thermoelectric Properties and Nanostructuring of Skutterudites;3. The synthesis approaches and its characteristic of skutterudite compounds,such as smelting,solid-state reaction,mechanical alloying and spark plasma sintering etc were reviewed.

回顾了熔融法、固相反应法、机械合金化和放电等离子烧结技术等方钴矿热电材料的制备方法及其特点，重点阐述了在方钴矿化合物中固溶Fe，Ni等元素，以及在方钴矿化合物中填充碱土或稀土元素对热电性能的改进；同时介绍了低维化对方钴矿化合物的热电传输特性的影响。

S profit is mainly decided by production costs of the common carbon steel andlowalloy steel, and by the change of the vanadic slag's selling price and different crudematerials and fuels and powers'price.

普碳钢和低合金钢的生产成本又与普通矿和钒钛矿的生产过程紧密相联，普通矿和钒钛矿二者所占的比例是随经济效益的变化而变化的。

This changes the costs and profit of the common oreand vanadic and titanic ore. The rate of the common ore and vanadic and titanic orechanges with the profit's change.

因此，找到普通矿冶炼和钒钛矿冶炼二者最佳的比例值，根据生产成本及市场价格的变化，及时调整普通矿冶炼和钒钛矿冶炼的比例，以获取最佳的经济效益是非常有意义的工作。

By actualize dead lime slaking technology,the blended mix and sintered ore size were improred,the sinter process was aggrandized,the question of white in sintered ore was solred,the production of simtered ore was adranced and quality was improved.

通过实施生石灰消化技术，改善了混合料及烧结矿粒度组成，强化了烧结过程，消除了烧结矿中&白点&问题，提高了烧结矿的产量，改善了烧结矿的质量。

The results show that insufflating 10～20mL MgCI2 Solution of 1.0 %～3.5% concentrations to 500g sinter can reduce the RDI of the sinter observably and have no influence on RI, and the integrative best effect of MgCI2 Solution is that the concentration is 2.5%, the amount of insufflations is 10mL and the RDI of the sinter is reduced from 36% to 4.4%.

结果表明：每500g烧结矿喷洒10～20mL浓度为1.0%～3.5%的MgCI2溶液，能显著降低烧结矿的RDI，且还原度不受影响，以500g烧结矿喷洒浓度为2.5%的MgCI2溶液10mL综合效果最佳，可使烧结矿的RDI从36%降至4.4%。

With long-term continuous search for mineral resources in the past, the opportunity in discovering the outcropped and shallow-seated deposits becomes increasingly difficult.

随着找矿、勘探与开发生产实践的不断深入，表露矿与浅部矿渐趋减少，找矿难度逐渐增大，找到一种简捷、迅速的勘查、探矿方式，迫在眉睫。
