So how to purity MAP is becoming key technology.

因此，如何有效除去肥料级磷铵料浆中的水不溶化合物杂质就成为工业级磷铵提纯生产的关键技术。

Soil carbon,soil total N,and pH belonged to high and soil total P belonged to medium degree spatial correlation at 60m lag intervals,respectively.However,there were significant differences in ranges of spatial autocorrelation among four soil properties,among which the effective range of soil organic carbon was the highest(261m),followed with soil total N(208m),pH(156m),and soil total P(133m).

在60m步长间隔尺度下，土壤有机碳、全氮和pH有强烈的空间相关性，土壤全磷空间相关性为中等程度。4种土壤养分的空间自相关范围具有明显的差异，有机碳的有效变程最大(为261m)，全氮(208m)和pH(156m)次之，全磷的有效变程最小(133m)。

However for P supply, DAP was found superior source and rock phosphate tended to be equally effective source of P in acid laterite soil.

不过对于磷素供应来说，磷酸二铵是最好的来源，磷矿粉在酸性红壤土上同样有效。

The potentiometric titration is implemented with lead nitrate standard solution.

在乙醇体系中，用硝酸铅标准溶液进行电位滴定，用二阶微分法分别确定全磷和硫酸根耗用硝酸铅的总体积，以及全磷耗用硝酸铅的体积。

There is an oxidation process in two determination methods of total N and total P, so the samples＇liquation and oxidation processes can be done simultaneously, and the standard curve can be acquired simultaneously by confecting blended standard solution, which simplifies the determination process of total N and total P.

由于二者测定时都存在将含氮、含磷化合物转化为硝酸盐和下磷酸盐的氧化过程，因此本研究考虑将污泥样品消解和样品的氧化过程同时进行，标准曲线也可以通过配制混合标准溶液来同时测定，这使得总氮、总磷测定流程得以简化。

The results show that the SI value of MAP is the logarithmic function of the mass concentration of P, of ammonium N and of Mg, respectively, and increases with the increase of the mass concentration of each element, The SI value of MAP is a polynomial function of the solution pH value, and the optimum pH value for the crystallization of MAP is 9.0 and increases slightly with the increase of N/P. Moreover, the SI value of MAP is a power law function of the solution ionic strength but decreases with its increase.

计算结果表明，磷酸铵镁的饱和度指数与氮、磷、镁的质量浓度分别呈对数函数关系，并随任何一个因子的增大而增大；与溶液pH值呈多项式函数关系，结晶反应的最佳pH值为9.0，并随溶液中氨氮与磷摩尔比的增大而略升；此外，磷酸铵镁的饱和度指数与溶液离子强度呈幂函数关系，随离子强度的增大而减小。

The result shown:the growth and development of P-deficient white lupine with cotyledons were not inhibited compared with the P-sufficient white lupine.

结果表明，子叶中的磷能使白羽扇豆在完全缺磷23 d的环境中，不仅没有使干物质的积累减少，反而使干物质的积累略有增加。

On the contray,when the cotyledons were removed,the responses of P-deficient white lupine got more intensive.The accumulation of dry matter reduced and more proteoid roots were induced.The accumulation and excretion of citric acid in/from proteoid roots were enhanced,in the mean time,the root tips could accumulate and secrete malic acid.

相反，如果没有子叶磷的供给，则使白羽扇豆在缺磷环境中产生强烈的抗胁迫反应，表现在干物质的积累明显下降，根系能产生大量的排根，排根能积累和分泌大量的柠檬酸，而根尖能积累和分泌苹果酸。

Methods 40 healthy adult mice were randomly divided into control group, CTX immune-suppressed group, Fb treated group, Fb combined with CTX treated group. The influences of Fb in NK cell activity were determined by the method of NK mediated cytotoxicity test;the multiplicative capacity of lymphocyte was assayed by lymphocyte transformation rate of T cell,and the mice spleen T lymphoblast multiplication analytical method was used to measure the IL-2 level.

健康成年小鼠40只，随机分为对照组、环磷酰胺免疫抑制组、黄蘑碱溶性多糖活性组分正常小鼠给药组和Fb环磷酰胺伍用给药组，采用NK细胞介导的细胞毒试验测定自然杀伤细胞的活性，淋巴细胞转化试验测定T淋巴细胞增殖功能，鼠脾T淋巴母细胞增殖分析法测定白细胞介素2（IL-2）的活性，观察Fb对各组小鼠免疫指标的影响。

Under the press of high content of calcium and magnesium in rocks, alkaline karst soil have low available forms of phosphorus and potassium in macroelement, high calcium and magnesium in middle element, enough necessary microelement except available form of boron, and more than 1 mg/kg cadmium of toxic element.

中药材金银花富集钙、镁、磷、钾、铜、锌等元素，对镉吸收低，适宜在岩溶地区种植。马尾松纯林受土壤低有效磷、钾和硼，高有效锌和钙的阻碍以及高镉的轻微毒害为不适宜树种。

For a big chunk of credit-card losses; the number of filings (and thus charge-off rates) would be rising again, whether
