A novel catalytic resonance light scattering method for the determination of traces of formaldehyde in blood plasma was developed. It was based on the fact that potassium bromate reacted with pyronine Y to form association nanoparticles which gave stronger resonance light scattering effect, and formaldehyde can catalyze potassium bromate oxidizing pyronine Y resulting in decreasing of the intensity of resonance light scattering in sulfuric acid.

在稀硫酸介质中，溴酸钾与吡啰红Y能聚集成较大粒径的纳米微粒而使共振光散射增强，而甲醛能催化溴酸钾氧化吡啰红Y而导致体系共振光散射减弱，据此建立了一种灵敏、简单、快速测定血浆中痕量甲醛的新方法。

Under lower potassium stress, the high efficiency ramie genotypes had higher growth potential (higher relative root dry weight, relative rootlet dry weight, relative root total and active absorb surface area), and higher relative fiber yield, decreased the negative effect of lower potassium stress on fiber quality validly.

但高效基因型苎麻低钾胁迫下仍具有较强的生长势（相对根系干重、相对细根干重、相对根系总吸收面积、相对根系活跃吸收面积较大），其纤维产量所受影响程度小于低效基因型，有效降低了低钾胁迫对纤维品质所引致的负面影响。

The conclusion was drawn by the synthesis of molecular sieve: after mixed soluble glass and aluminium sulfate with proper proportion under room temperature, it was stirred stormily to react. And then we mixed with potassium hydroxide solution after filtrating. At last, the molecular sieves of potassium type was synthesized after the mixture reacted in the oven or autoclave for 24 hours. The molecular sieve was remodeled more than twice with ammonium chloride solution that the concentration was 3mol/L and then remodeled twice with the saturated sodium chloride solution. Finally the molecular sieve was changed into the sodium type. It was named W zeolite.
