本文引用了胶体化学的观点和方法及显微镜观察技术,研究了江西红壤中的胶结物质和结构形成的关系。结果表明,不同土壤中的胶结物质大致可分成三类:(1)以无机胶结物质为主(如第四纪红色粘土母质);(2)无机胶结物质和有机胶结物质(如旱地红壤);(3)以有机胶结物质为主(如乌泥田)。三类胶结物质中的胡敏酸含量是以第四纪红色粘土中为最少,旱地红壤中稍高,乌泥田中最多,胡敏酸和富里酸的比值相应为0.1—0.2,0.5—0.7及1。胡敏酸和富里酸的比值并不决定于有机碳总量,而在一定程度上与耕作水平密切相关。看来肥沃的土壤要大些。三类胶结物质所形成团聚体的孔隙性,以第一类为最低(30%),第三类为最高(40%)。各类团聚体中的脂蜡物质、游离态有机胶结物质和胡敏素含量,在绝大多数情况下,是随着团聚体粒径的减小而减少。当土壤含有机质较少时,团聚体中与有机质结合的无定形三氧化铁和无定形三氧化铁的含量是随着团聚体粒径的減小而增多。良好团聚体的形成要通过多种多样的结合作用,既由胡敏素结合成稳定性很大的微团聚体,又有由较新鲜的有机胶结物质把微团聚体结合为大团聚体。这种大团聚体既有一定的水稳性,又具备多孔性及养分速效性的特点。土...

A conclusion that eutectic graphite is directly segregated from molten iron and then grows has been made in some earlier works[2, 3, 4].This paper, differing from such a conclusion, puts forward a new idea on the subject of graphitization in cast iron through thermodynamic analysis and experiments by x-ray and electron diffractions for eutectic molten iron with a high cooling speed of about 106℃/sec.

A conclusion that eutectic graphite is directly segregated from molten iron and then grows has been made in some earlier works[2, 3, 4].This paper, differing from such a conclusion, puts forward a new idea on the subject of graphitization in cast iron through thermodynamic analysis and experiments by x-ray and electron diffractions for eutectic molten iron with a high cooling speed of about 106℃/sec. It is true that the short-sequence graphites exist in free state in eutectic molten iron at the lower superheating temperature. However, the decomposition of Fe3C also plays an important role under graphitization so that it may be considered as an indirect graphitization process, which should not be overlooked. Here the critical temperature Tk(℃) as a parameter dependent to a considerable degree on the chemical composition is introduced. It is favourable for the formation of Fe3G and also the Fe3C is more stable than the graphite in molten iron when the temperature exceeds Tk. If the temperature is below Tk, Fe3C will be in an unstable state and will tend to decompose into Fe and C spontaneously. An relatively all-sided conclusion is probably such that the short-sequence graphite in free state can nucleate graphites in cast iron; however, the carbons supplied by the decomposition of Fe3C also play a positive role for the growth of graphites.

过去文献中,有的认为共晶石墨是从液态铁水中直接析出长大的。本文通过热力学分析和对共晶铁水,对以 10~6℃/s 的高速冷却条件下制取的试样,进行X光、电子衍射等分析,得出不同于以上结论的看法。认为一方面当过热度不高时,在共晶态的液态铁水中虽已有游离态的石墨短程序存在;但另一方面在石墨结晶过程中 Fe_3C 的分解也是重要的,(即间接石墨化过程),不容忽视。高于临界温度 T_k 时,有利于 Fe_3C 的形成,且Fe_3C 比石墨更稳定;低于 T_k 时则 Fe_3C 不稳定,有自发分解为 Fe 与C的倾向。T_K 受化学成份的影响很大。可以认为,游离的石墨短程序固然是石墨结晶的核心,但在石墨长大的过程中,由于 Fe_3C 的分解而提供的碳也起很大作用。

The results of the study on aquatic vascular plants under cadmium (Cd~(++)) pollution show that there is a significant negative correlation between chlorophyll content and Cd~(++) concentration but a strong positive correlation between permeability of cell membrane in the leaf, as judged by exosmosis, and Cd~(++) concentration. Soluble sugars in the leaves of the various species tested increased with the increase of Cd~(++) concentration though the rate of increase is much slower in the resistance species. The...

The results of the study on aquatic vascular plants under cadmium (Cd~(++)) pollution show that there is a significant negative correlation between chlorophyll content and Cd~(++) concentration but a strong positive correlation between permeability of cell membrane in the leaf, as judged by exosmosis, and Cd~(++) concentration. Soluble sugars in the leaves of the various species tested increased with the increase of Cd~(++) concentration though the rate of increase is much slower in the resistance species. The activity of dehydrogenase extracted from the root was inhibited by Cd~(++), the inhibition being more pronounced as Cd~(++) concentration increased. Changes in peroxidase isozyme pattern in the plant species studied were related to the Cd~(++) concentration used. The changes reported are useful and effective indices in monitoring the environment.

镉污染后的水生维管束植物其叶绿素a/b值随水体镉浓度的增加而下降,叶绿素含量与镉浓度呈极显著的负相关。叶细胞膜透性与镉浓度呈极显著的正相关。不同抗性种叶片可溶性糖含量均随镉浓度增加而升高,但抗性种的增加率要小得多。镉对根系脱氢酶的活性产生抑制,且随镉浓度升高,活性相应下降。对过氧化物酶同工酶谱也产生明显的影响。这些在环境监测中可作为生理指标。凝胶层析表明,具有抗性的凤眼莲的可溶性成分中,存在着高分子镉复合物(>70,000)、分子量为13,300的镉复合物和低分子量镉螯合物及游离态镉。不抗种的紫背萍缺乏第二种镉复合物。
