磷

But the effect of N to P is much more remarkable than the influence of P to N.

磷对氮的影响远远小于氮对磷的影响。

Phosphorus is an essential element of life, which participates in almost all the life process directly or indirectly.

磷是生命的中心元素，所有的生命活动过程都直接或间接有磷的参与。

A successional Artemisia ordosica and A. frigid community, located on the eastern edge of the Tengri Desert in Alashan Left Banner, Inner Mongolia, was selected as an object for study. Densities of the plants and total nitrogen and available phosphorus in 0~20 cm soil layer were measured of the 400 quadrates (4m×4m) in the sampling plot (80m×80 m) for analysis of relationship between N/P ratio in the soil and plant density thereupon and between the two in spatial heterogeneity.

选择腾格里沙漠东缘内蒙古阿拉善左旗境内的油蒿＋冷蒿群落为研究对象，在80m×80m样地400个4m×4m样方中，调查了油蒿和冷蒿的密度，测定了0~20cm土层中的全氮和有效磷，分析了土壤氮／磷比与植物密度之间及其空间异质性之间的关系。

This is believed to be conneeted with the depletion of Mo, a scavenger of P, in matrix due to the Mo tithed carbides formation during preaging. Therefore, more P is released and segregated to grain boundaries. Carbide coarsening perhaps contributed to the increment in transition temperature too.

Mo可抑制磷的偏析，但因时效过程中富Mo碳化物的生成和长大，使基体中Mo的含量降低，因此，磷从Mo的&束缚&下&解放&出来并偏析到晶界，使脆性转变温度升高，此外，碳化物的粗化也可能导致脆性转变温度升高。

Our research also revealed that phosphate starvation evidently increased the proton translocating activity of the two enzymes of proton pumps in vecuolar membranes of the roots of tomato seedlings,which reached the highest degree under phosphate starvation for 7 d.

研究结果还表明，磷饥饿能够明显促进番茄幼苗根部液泡膜依赖于质子ATP酶和焦磷酸酶的质子转运活性，其中，磷饥饿第7d时的促进作用最为显著。S

Nitrogenase activity of nitrogen-fixing bacteria was measured by acetylene reduction assay combined with gas chromatography.

运用乙炔还原法测定了固氮细菌的固氮酶活性，通过测定菌落周围产生的透明圈和混浊圈大小对磷细菌的溶磷活性进行比较，采用火焰分光光度计测定了钾细菌的解钾活性。

The 'acid' Bessemer process, as the Victorian ironmasters discovered , could not eliminate phosphor, which is harmful to steel, so low phosphoric pig irons had to be used.

维多利亚女王时代的铁器制造商发现，酸性贝塞麦工艺不能去除对钢有害的磷，所以必须用低磷生铁进行冶炼。

Is the production of phosphoric acid and phosphate products mainly phosphorus chemicals joint-stock enterprises.

四川什邡鼎立磷化工有限公司是以生产磷酸及磷酸盐系列产品为主的磷化工股份制生产企业。

A new production process is proposed,in which the acid sludge is removed and the pickling liquor is neutralized once with lime milk after defluorination .

工业试验结果表明，新工艺能使磷矿石中磷的利用率由现有工艺的近60%提高到85%以上，脱氟液中磷氟质量比由240左右提高到300以上，产品收率提高20%以上，产品质量也大大提升，并显著降低了原料消耗及生产成本。

Based on practice and analysis, it is put forward that the effective decrease of residual P2O5 in phosphorus furnace slag depends on the control of acidity coefficient from the slagging and reduction of P2O5. Also a relative formula for the calculation of acidity coefficient is presented.

结合生产及理论分析，指出在控制磷炉渣酸度系数中，必须兼顾满足造渣和还原反应两方面的要求，才能有效降低磷炉渣中残留的P2O5量，并且推导出相应的计算式，以消除酸度系数控制的局限。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
