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。

It is suggested by our test work on radon mapping of geology that there is a good coincidence between the data got from gamma-ray spectrometer and radon monitor and the U、Th、Ra、K data got from indoor gamma-ray spectrometer and radiochemistry method; the data of gamma-ray spectrometer and radon monitor are also comparative to the 1∶20 ten thousand geochemistry data of U、Th、 Ra (calculated by the equilibrium coefficient between U and Ra) and radon concentrations measured by solid state nuclear track detector .

在国内首次利用地质勘探费用进行氡地质填图方法试验，该试验方法结果表明，利用国产的现场能谱仪、测氡仪获得的数据与室内能谱仪、化学法测得的铀、钍、镭、钾结果一致；与已有的1∶20万区域地球化学数据铀、钍、镭（由铀、镭平衡系数计算得出）、钾和固体核径迹累积法测氡数据具有很好的可比性。

The rate of spatial variability of available P and available K were large than 20%, and their area rate of relative uniformity were individually 82.18% and 94.99%, which large than 80%.

This paper aims to find out the nutrition characteristics and fertilizer absorption rule of Castor in arid red soil districts under the subtropical climate of Yunnan province, and establish a corresponding fertilizing technology under the condition. It choose the variety TCO-202 of Castor (Ricinus communis L.) as test material to observe and record the dry matter accumulation of each organ as root, stem, foliage and inflorescence, which are in the five critical growth stages as seedling stage、 bud stage、 blooming stage、 filling stage、 maturation stage of Castor {Ricinus communis L. respectively, and measure out the fertilizer absorption amount of nitrogen, phosphorus and potassium.

本文以云南北亚热带气候下的红壤旱地为试验条件，选用蓖麻品种TCO-202为试验材料，通过对苗期、现蕾期、开花期、灌浆期、成熟期五个蓖麻生长关键时期根、茎、叶、花序各器官的干物质积累和氮、磷、钾吸肥量的测定，研究云南红壤上蓖麻的营养特性和吸肥规律；依据蓖麻的营养特性和吸肥规律，结合云南红壤氮、磷、钾的含量与利用效率，制定适合云南红壤上蓖麻栽培的施肥技术研究方案。

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。

It is based on the facts that in the presence of sulfuric acid and sodium dodecyl benzene sulfonate, vanadium activated by vitamin C can catalyze potassium bromate to oxidize safranine O, the oxidation products of safranine O can emit intense and stable fluorescence on nitrocellulose membrane.
