磷酸盐

The structures of borates and borophosphates are primarily influenced by polyanions,and in borates M_xB_yA_z the number of coordination of B atoms increases with theelectronegativity of A atoms.

硼酸盐及硼磷酸盐的结构主要来自聚阴离子的影响，A代硼酸盐中，A的电负性越大，B的共价配位数越高。

Some organic insecticides are natural, such as rotenone, pyrethrins, and nicotine. Others are synthetic, such as chlorinated hydrocarbons (e.g., DDT, dieldrin, lindane); carbamates, related to urea (e.g., carbaryl, carbofuran); and parathions, organic phosphorus ester s.

有机的杀虫剂可能是天然的，如鱼藤酮、除虫菊和尼古丁；或是合成的，如氯代烃类(例如，滴滴涕、狄氏剂、林丹)、氨基甲酸酯，与尿素有关(如氨基甲醯、灭多虫和卡甲喃)、巴拉松、有机磷酸盐。

In the carbon- and nitrate-limited chemostats phosphate (10 mM) was evidently supplied to the cultures in excess.

在碳- 和硝酸盐-有限的 chemostats 磷酸盐(10 毫莫耳)明显地被供应到过度的文化。

Hydration resistances of synthetic MgO-CaO clinkers treated by polyphosphate were studied.

研究了合成MgO -CaO砂在聚磷酸盐溶液中处理后的抗水化性能，探讨了热处理温度及不同工艺条件对其性能的影响。

Department of Chemical Pharmacology, Capital University of Medical Science, Beijing 100054, ChinaAbstract: A reversedphase high performance liquid chromatographic method was developed for the simultaneous quantitative determination of caffeine, dapsone and chlorzoxazone. The operation was carried out on a C18 column (250 mmX4.6 mm i.d., 5.0 μm) with the mobile phase of acetonitrilephosphate buffer including 0.02 mol/L KH2PO4 and 0.02 mol/L (C2H53N, pH 6.5(25:75 in volume ratio).

用反相高效液相色谱同时测定血清中咖啡因、氨苯砜、氯唑沙宗探针药物的质量浓度，以乙腈磷酸盐缓冲体系(含 0.02 mol/L的磷酸二氢钾和0.02 mol/L的三乙胺，pH 6.5)(体积比为25：75)为流动相，以安替比林为内标，经C18柱(250 mmX4.6 mm i.d。， 5.0 μm)分离，紫外检测器检测，使3种探针药物得到较好的分离，并且在有效血药浓度范围内线性良好。

In a sense, phosphate is taken out of circulation in the Ecosphere, diminishing the prospects of more life.

从某种意义上说，把磷酸盐带动了这个生态球中的循环，逐渐缩小产生更多生命的可能性。

In a sense, phosphate is taken out of circulation in the Ecosphere, diminishing the prospects of more life.

从某种意义上，这就等于说磷酸盐已经退出了这个生态球中的循环，从而逐渐缩小了产生更多生命的可能性。

In a sense, phosphate is taken out of circulation in the Ecosphere, diminishing the prospects of more life.

从某种意义上，这就等于是说磷酸盐已经退出了这个生态球中的循环，从而也就取消了产生更多生命的可能性。

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。
