二氧化碳因温室效应而臭名昭著,几乎成了全人类的"公敌";如今再提"氮的不良作用有甚于碳",似乎有故作玄虚、哗众取宠之嫌。然而人类为了提高农作物产量正在不断地施加氮肥,其中只有小部分被吸收利用,而大部分则和含氮污水一同流入湖泊、水库、河口、海湾等缓流水体。那些地方的浮游生物尤其是藻类便大量繁殖,相反水底生植物则因光合作用受到阻碍而死去,其腐败后所释放出的氮、磷等营养物质再供藻类利用。这样年深月久,难免不步入恶性循环圈:藻类越是大量繁殖,水质越是恶化;水质越是恶化,藻类越是大量繁殖,结果堪忧———科学家们将其称为富营养化(eutrophication),实在是某种程度的"自我解嘲"!

Background The effect of microbial phytase on amino acid and energy digestibility is not consistent in pigs,which may be related to the phytase dosage or the adaptation length to the ***,an experiment was conducted to test the hypotheses that increasing dietary phytase after an 18-day adaptation period:1)increases nutrient and energy digestibility;2)increases plasma P,plasma inositol,and bone ash of young pigs;and 3)demonstrates that maximum phytate degradation requires more phytase than maximum P *** Data indicated that increasing inclusion of phytase[0,250,500,1,000,2,000,and 4,000 phytase units(FTU)/kg feed]in corn-soybean meal-based diets increased apparent ileal digestibility(AID)of Trp(quadratic;P<0.05),and of Lys and Thr(linear;P<0.05),and tended to increase AID of Met(linear;P<0.10).Increasing dietary phytase also increased AID and apparent total tract digestibility(ATTD)of Ca and P(quadratic;P<0.05)and increased ATTD of K and Na(linear;P<0.05),but phytase did not influence the ATTD of Mg or gross *** of plasma P and bone ash increased(quadratic;P<0.05),and plasma inositol also increased(linear;P<0.05)with increasing inclusion of *** concentrations of inositol phosphate(IP)6 and IP5(quadratic;P<0.05),reduced IP4 and IP3(linear;P<0.05),but increased inositol concentrations(linear;P<0.05)were observed in ileal digesta as dietary phytase *** ATTD of P was maximized if at least 1,200 FTU/kg were used,whereas more than 4,000 FTU/kg were needed to maximize inositol *** Increasing dietary levels of phytase after an 18-day adaptation period increased phytate and IP ester degradation and inositol release in the small ***,increasing dietary phytase resulted in improved digestibility of Ca,P,K,Na,and the first 4 limiting amino acids,and in increased concentrations of bone ash and plasma P and *** a corn-soybean meal diet,maximum inositol release requires appr

Dear Editor,This letter proposes a parameter-free multiple kernel clustering(MKC)method by using shifted Laplacian *** MKC can effectively cluster nonlinear data,but it faces two main challenges:1)As an unsupervised method,it is up against parameter problems which makes the parameters intractable to tune and is unfeasible in real-life applications;2)Only considers the clustering information,but ignores the interference of noise within Laplacian.
