When TiO〓 content is increased, the surfacial energy formed by crystals may be reduced, the devitrification degree, strengthened and the content of wollastonite in crystal phase raised; if Cr〓O3〓 content is increased, the crystal size is enlarged, and the content of diopside in crystal phase, raised; if the sulphide content is increased; the reduction atmosphere is heightened and the content of wollastonite become bigger.

晶核剂浓度研究表明，晶核剂浓度不同，对基础玻璃析晶强度，晶相含量和晶体尺寸有一定的影响，当TiO〓含量增加时，可以降低晶体形成的表面能，析晶强度增大，晶相中硅灰石含量增多；Cr〓O〓含量增加，晶体尺寸增大，晶相中透辉石含量增加；硫化物增多，还原气氛增大，同时硅灰石含量增多。

Vulcanization thing in sulphur natural gas, take off to exclude, Make organic sulfur content and the vulcanization hydrogen of the natural gas of raw material accord with relevant technical index requirement , satisfy production needs,Today of the chemical swift development of natural gas the desulphurization method of natural gas also emerge endlessly , In traditional a ethanol amine the foundation of wet desulphurization and the dry law desulphurization of zinc oxide on, have arisen the desulphurization of normal temperature of ferric oxide, the dry law desulphurization of activated carbon and member sift desulphurization, DDS biochemical wet desulphurization wait for new technology .

硫的存在造成合成氨工艺中催化剂中毒，因此需将含硫天然气中的硫化氢、有机硫等硫化物脱除，使产品天然气的硫化氢和有机硫含量符合有关技术指标要求，满足生产需要。在天然气化工迅猛发展的今天，天然气脱硫方法也层出不穷。在传统一已醇胺湿法脱硫，氧化锌干法脱硫的基础上，出现了常温氧化铁脱硫，活性炭干法脱硫，分子筛脱硫，DDS生化湿法脱硫等新技术。

This article analyzed the pollutant source in everglade of Dongting Lake, based on investigate data from hydrological observation station of Dongting Lake, environmental monitor station and spots examine.
