特别提到昆明理工大学精细化工教研室，开展了肥料级磷酸一铵水溶液添加一定的净化剂，可使磷酸一铵水溶液达到合成三聚磷酸二氢铝的要求。

The separation was achieved within 4 min using a BEH Shield RP18 column (100 mm 2.1 mm, 1.7 μm) with 50 mmol/L monoammonium phosphate solution (pH 6.5) and acetonitrile as the mobile phase.

以BEH Shield RP18柱(100 mm 2.1 mm，1.7 μm)为分析柱，以50 mmol/L的磷酸二氢铵(pH 6.5)和乙腈为流动相进行梯度洗脱，3种磷酸腺苷在4 min内实现了较好的分离。

The results showed that CRMP had higher phosphorus availability in soil and the changes ofavailable P concentration in both root zone and non-root zone soil were more reasonable during the sorghum growing season as compared to common monoammonium phosphate.

与普通磷酸一铵相比，控释磷酸一铵施入土壤后磷的有效性较高，无论是近根区还是非根区土壤有效磷随时间的变化分配更趋于合理。

In order to make WRCRFs with good performance, the raw material fertilizers with smaller effects on HWAR such as urea, monoammonium phosphate and potassium chloride should be selected. On the other hand, for HWAR, high stability and adequate WAR such as polyacry lamide graft polymer should be needed.

制造性能优越的保水型控释肥，应尽可能选择对HWAR稳定性影响较小的尿素、磷酸一铵、氯化钾等原料肥料，对于包膜材料则应选择稳定性高且具适度吸水倍率的聚丙烯酰胺型HWAR。

Key words: monoammonium phosphate; neutralized slurry concentration process; purifying phosphoric acid; the process of fertilizer integrated with salt; equipment

磷酸一铵；中和料浆浓缩法；净化磷酸；肥盐结合工艺；装备

The amount of Ca8-P in soil with CRMP treatments was lower than that of CMP treatments. The changes of the amount of Al-P, O-P, Fe-P and Ca10-P in soil were neglectable during the course of experiment.3. The shoot and root weight of sorghum increased through application of phosphorus, in addition, The increase of sorghum shoot and root weight was greater than that of common monoammonium phosphate due to the slow release of nutrients from CRMP. The accumulative uptake of phosphorus in shoot and root with CRMP treatment was greater than that with CMP treatment in low (75 mg P2O5/kg soil ) and high（150mg P2O5/kg soil）rates, especially on middle stage, and in high phosphorus rate, this advantage was more obvious than that in low phosphorus rate.

磷肥的施入，促进了高粱地上部和根部的生长，而控释肥由于缓慢释放养分，与作物吸收相一致，更能促进高粱的地上部和根部干物质积累；对于高粱地上部及根部的磷素累积，在两种施磷水平下控释处理地上部及根部磷素累积量均大于非控释处理，尤其是在中期，而且高磷水平下优势更加明显，低磷控释处理的磷素累积量能达到高磷非控释的累积量，即减少一半的用量即能达到同样的效果；在氮、钾、钙、镁相同的水平下，控释处理比非控释处理更能促进地上部及根部氮、钾、钙、镁累积量，这种优势在中期表现最明显。4。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
