secondary inclusion

According to genetic difference , the secondary inclusion of gems can be divided into original - secondary inclusion , post - secondary inclusion and man-made secondary inclusion .

宝石的次生包裹体根据成因不同可划分为原次生包裹体、后次生包裹体和人工次生包裹体3种类型。

The different kind of secondary inclusion shows the different characteristics .

次生包裹体的类型不同，所表现的特征也不同。

Genetic classification of gems secondary inclusion and characteristics

宝石次生包裹体的成因分类及表现特征探讨

Man-made secondary inclusion is formed in the proceeding of optimizing treatment of gems .

人工次生包裹体指人为性对宝石进行优化处理的过程中形成的包裹体。

On the basis of the close connect between diagenesis and accumulation events , the phase of hydrocarbon accumulation is analyzed according to distribution of homogenization temperature from secondary fluid inclusion , and the data of carbon and oxygen isotope in authigenic mineral of carbonate from fracture .

立足成岩作用与成藏事件的紧密联系，根据次生包裹体均一温度、自生碳酸盐矿物的碳、氧同位素资料分析了成藏期次；

The 1 ∶ 3 ∶ 5 cross sectional area ratio of the sprue , runner and gate and the rational fissure with cushion structure make the molten metal fill stably in the mould cavity , that reduce the secondary oxide inclusion and the invading gas ;

直浇道、横浇道和内浇道截面比为1∶3∶5，并配合带缓冲结构的合理缝隙，可保证型腔内液面上升平稳，减少铸件内部二次氧化夹杂和混入性气体；
