The dispersion mechanism of the dispersants was analyzed by testing the Zeta potential of the dispersion phase in the dispersion medium. It was shown that Ⅰ and Ⅱ raised obviously the absolute values of surface Zeta potential of titania particles, and NK-1 formed good solvate layers of the particles so that the nano-titania particles were stably dispersed in the water solns.

So a spectrophotometric method is developed for the determination of sodium nitroprusside in the injection solution of sodium nitroprusside.

由此建立了测定硝普钠注射液中硝普钠含量的新的分光光度分析法。

The results showed that the size of spherule formed with 5% of SA and 11% of PVA was appropriate and elastic, furthermore, 5% SA could keep the enzymatic activity better, it is higher by 16% than 11% PVA, therefore, it is the optimum immobilization conditions.

研究结果表明，5%的海藻酸钠、11%的聚乙烯醇形成的固定化菌球大小合适，有弹性，但5%的海藻酸钠能更好的保持酶活性，比11%聚乙烯醇高16%，其为最佳的固定化条件。

In the meantime, kidney spherule filtration is led is decelerated, uric natrium is excreted reduce; kidney canaliculus to answer absorptivity to reduce, make kidney canaliculus also decreases to be being absorbed of sodium again, reason is easy produce liquid and electrolyte to lose a balance, this kind of case will come continuously after be born the 2nd, 3 weeks.

同时，肾小球滤过率减慢，尿钠排泄减少；肾小管回吸收率降低，使肾小管对钠的重吸收也减少，故易发生液体和电解质失平衡，这种情况将会持续至出生后第2、3周。

II: ① take a thin wire, one end with sand paper wipe, and then lightson alcohol to non-yellow flame ignition,② wire with the end of the water dip, and then dip a number of sodium chloride or anhydrous sodium carbonate powder,③ ignited a new spirit lamp (lamp wick is clean, pure ethanol),④ the stained sodium salt powder on the wire on the ignitiontip, when there is a sharpsmall yellow flame, which is sodium flame.

方法二：①取一条细铁丝，一端用砂纸擦净，再在酒精灯外焰上灼烧至无黄色火焰，②用该端铁丝沾一下水，再沾一些氯化钠或无水碳酸钠粉末，③点燃一盏新的酒精灯，④把沾有钠盐粉末的铁丝放在外焰尖上灼烧，这时外焰尖上有一个小的黄色火焰，那就是钠焰。

The technological flow for directly preparing sodium stannate from the low grade tin ore (containing tin 20%￣30%) has been studied.

研究了用低品位锡矿（含锡20％～30％）直接制取锡酸钠的工艺流程，即把锡矿先进行还原焙烧，然后用NaOH溶液浸出，最后把溶液浓缩结晶制成锡酸钠产品。

The antimony doped tin oxide nanoparticles were synthesized at 240℃for 17 h by the complexing hydrothermal oxidation method using stannate, antimony white and sulphuric acid as the starting materials, sodium hydrotartrate as the complexing agent and hydrogen peroxide as the oxidant. The resulting powders were characterized by means of differential thermal analysis, infrared spectrometry, X-ray diffraction and transmission electron microscope. The mechanism of the preparation of ATO powder was investigated as well.

摘 要：以锡酸钠、锑白和硫酸为原料，酒石酸氢钠为配合剂，双氧水为氧化剂，采用配合水热氧化法在水热氧化温度为240℃和水热保温时间为17 h时，合成单分散性的蓝色锑掺杂二氧化锡粉末，用差热分析、红外光谱、X射线衍射和透射电镜对所制得的粉末进行表征，并对ATO纳米粉体的配合水热氧化合成机理进行探讨。
