The results show that:(1) after MA for 20h, single phase bcc nanocrystalline supersaturate solid solution formed in Fe84Nb7B9 and Fe80Ti8B12 alloys; the thermal stability of nanocrystalline microstructure in Fe80Ti8B12 alloy was improved significantly than that in Fe84Nb7B9 alloy, and the decomposition temperature of supersaturate solid solution decreased in Fe80Ti8B12 alloy.(2) under 30MPa/900℃/0.5h hot-press sintering conditions, the relative density of Fe84Nb7B9 and Fe80Ti8B12 bulk alloys were 96.7% and 95.5%, respectively. Compared with Fe84Nb7B9 alloy (muti-phase microstructure), Fe80Ti8B12 alloy was composed of superfine crystalline (50~200nm) of single phase α-Fe;(3) the magnetic properties of Fe80Ti8B12 bulk alloy σ(subscript s=198.6emu/g, H=54.6Oe were more excellent than that of Fe84Nb7B9 bulk alloy σ(subscript s=162.9emu/g, H=105.1G, it was related to the different phases formed during hot-press sintering and the grain size of nanocrystalline powder.

结果表明：(1)20hMA后，Fe84Nb7B9和Fe80Ti8B12均形成了单相bcc纳米晶过饱和固溶体，相对前者，后者纳米晶组织热稳定性明显提高，过饱和固溶体相分解温度略有降低；(2)在30MPa/900℃／0.5h热压条件下，Fe84Nb7B9和Fe80Ti8B12块体合金相对密度分别为96.7%和95.5%，相对前者，后者由超细晶(50~200nm)单相α-Fe组成；(3)Fe80Ti8B12块体合金软磁性能σ(下标 s=198.6emu/g，H＝54.6Oe明显高於Fe84Nb7B9块体合金σ(下标 s=162.9emu/g，H＝105.1Oe，此与纳米晶粉末在热压烧结过程中所形成相的种类和晶粒尺寸大小有关。

Ca(superscript 2+), and Ba(superscript 2+) has obvious role to increase its activity.

Ca(上标 2+)、Ba(上标 2+)对提高酶活力具有明显作用。

The strain JK(superscript * subscript 14) with rifampicin and wheat take-all disease resistance was screened by increasing concentration of the two substrates, and colonization of JK(superscript * subscript 14) was studied.
