为研究溪黄草(Rabdosia serra(Maxim.)Hara)浸提液对杂草种子萌发与幼苗生长的化感作用,本试验以稗草(Echinochloa crusgalli L.)和马唐(Digitaria sanguinalis L.)为受体材料,采用培养皿滤纸法测定了稗草与马唐的种子萌发、幼苗形态和生理指标。结果表明:(1)溪黄草鲜样浸提液在80 mg·mL^(-1)时,对马唐与稗草种子的萌发和根长起到显著的抑制作用(P<0.05);(2)随着溪黄草干样和鲜样浸提液浓度的升高,稗草的过氧化物酶(Peroxidase,POD)和过氧化氢酶(Catalase,CAT)活性显著升高,而马唐的POD和CAT活性则显著降低(P<0.05);(3)当溪黄草干样和鲜样浸提液浓度为20,40,80 mg·mL^(-1)时,对马唐的化感综合效应表现为抑制作用,且浸提液浓度越高抑制作用越强。综上所述,溪黄草浸提液在浓度为80 mg·mL^(-1)时,对马唐种子萌发和幼苗生长具有显著的抑制作用(P<0.05)。

The classical Levy-Meixner polynomials are distinguished through the special forms of their generating functions. In fact, they are completely determined by 4 parameters： c1, c2,γ and β. In this paper, for-1 〈q〈 1, we obtain a unified explicit form of q-deformed Levy-Meixner polynomials and their generating functions in term of c1, c2, γand β, which is shown to be a reasonable interpolation between classical case （q=1） and fermionic case （q=-1）.In particular, when q=0 it＇s also compatible with the free case.

By means of isothermal oxidation and chemical analysis, great importance was attached to the parameters that made effects on the oxidation degree of vanadium, titanium-bearing magnetite pellet in high-temperature processing （1 073- 1 323 K）. Based on the experimental data, oxidation kinetics of pellet was analyzed according to shrinking unreacted-core model subsequently. Experiment results display that the oxidation degree of pellet increases with increasing of oxidation time, oxidation temperature and oxygen content, as well as shrinking of pellet diameter. Under the condition of oxidation time 20 min, oxidation temperature 1223 K, oxygen content 15%, and pellet diameter 12 mm, oxidation degree of pellet reaches 92.92%. The analysis of oxidation kinetics indicates that oxidation process of pellet is controlled by chemical reaction with activation energy 68.64 kJ/mol at a relatively lower temperature （1073-1 173 K）. Oxidation process of pellet is mixed-controlled by chemistry reaction and diffusion with activation energy 39.66 kJ/mol in the temperature range of 1 173-1 273 K. When oxidation temperature is higher than 1 273 K, the limited link of oxidation reaction is the diffusion control with the activation energy 20.85 kJ/mol. These results can serve as a reference to the production of vanadium, titanium-hearing magnetite pellet.
