结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

The result shows that modification can make the β-Si phase thin when the joining amount is 0.3wt%, making the best modification result. Alloying elements Mn and Ni are always used to neutralize iron"s harm in aluminum alloys. They can form many kinds of complicated metallically compounds with Fe and Al, and eliminate needle-like iron-rich phases to reduce iron"s harm in Al-Fe alloy. Copper makes the alloy microstructure thick and electromagnetic stirring obviously makes the alloy microstructure thin, round the second phase, when the stirring voltage is 200V, making the best result; Reheat makes liquid phases emerge in the alloy, when the warming temperature is 650?

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...
