TCP porous ceramics, as a system among bone-defectsrepairing materials, have immeasurable advantage compared with the otherbiomaterials. But at the same time, the preparing process and osteogenetic processof this kind of material are very complicated, and to the material's Ca, Pcomparison and micro-construction is expected extremely high.

TCP多孔陶瓷作为骨替代材料中的一员，有着其它生物医用无机材料无可比拟的优势，但同时，这种材料的制备工艺及在生物体内的降解和成骨过程也比较复杂，材料的Ca、P比例以及微观结构的要求也更高。

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.

目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式，一是运用同位素地质温度计原理，利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系，对湖泊古水温做定量研究；二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温；三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。
