指出对测氡仪器必须进行标定，而且必须用流通式氡气源来标定；在观测中应控制或测定进入闪烁室的气体流量。

This paper consults the key technology in the radon measurement device in the national and international and we thinks over the characteristic of α-ray which emit by radon and its daughter, so that decides to use the α-ray spectrum to measure radon.

论文从测量氡及其子体放射出的α射线入手，瞄准国内外测氡装置关键技术发展趋势，结合氡及其子体α能谱测量特点，采用α能谱测氡的途径来完成这一工作。

The radon concentration rises with depth which may be distorted by radon daughters and thoron .(2). Seasonal temperature influence free radon of soil only.

季节温度仅对壤中活动氡运移有影响，对束缚氡影响小；认为温度梯度也是引起空气中氡浓度日变的一个因素；（3）。

Six field measurement sections with dozens kilometers were performed with a real-time radon gauge and a air radon gauge , financed by Chinese Geological Survey. The results show that the Radon concentration is 6.7 Bq/L in field soil and 16.7 Bq/m3 in the air .

在中国地质调查局&四川成都经济区域城市生态地球化学评价&项目的成都市地空界面氡浓度的调查与评价实践中，进行了大量的实验和野外测量，结果表明成都市原野壤中氡浓度水平平均值为6.7Bq/L，空气中平均氡浓度为16.7 Bq/m~3，土壤中氡浓度整体是西部和东部偏高。

Seed was stored in a storage temperature, the galactose content of seed decreases as the seed moisture content decrease. However, the glucose, fructose, sucrose and raffinose content of seed increase as the seed moisture content decreases, but this kind of change is not clear if seed was stored at lower temperatures ranges from 20℃ to -18℃.

然而葡萄糖、果糖、蔗糖和密三糖的结果与半乳糖的变化趋势相反，随着贮存温度的升高，四种糖的含量逐渐下降，在同一贮藏温度条件下，随含水量的降低，这四种糖的含量却逐渐升高，但在贮存温度较低时(20℃和-18℃)，这种变化趋势不明显。

The mutagenicity of seed powder and seed oil of transgenic CryIA cotton to mammals and fish was evaluated in this study. The raw cotton seed powder or seed oil was mixed into mice and fish's diet. Cyclophosphamide and NaF were used as positive controls respectively. Regular cotton seed powder and seed oil were used as negative controls. The micronucleus frequency in mice bone marrow polychromatic erythrocytes and in eripheral erythrocytes of Zebrafish were assayed in this study. The sperm malformation rate in mice was also investigated.

摘 要：分别以环磷酰胺和氟化钠作为阳性诱变剂，以普通棉的棉籽粉及棉籽油作为对照物，同时设阴性对照组，以成年封闭群昆明种雄性小鼠和斑马鱼为实验材料，将棉籽粉或棉籽油掺入饲料中饲喂小鼠或斑马鱼，检测小鼠骨髓嗜多染红细胞（Polychromatic erythrocytes， PCE）微核率（Micronucleus frequency， MN‰）和精子畸变率，以及斑马鱼外周血红细胞微核率。

China introduced TQM at the end of 1970s to improve the quality of its industry product but did not make enough progress because the project was impelled by the administration. Since the year of 2000s, monopoly in Chinese seed industry has been broken down and the market is growing rapidly, seed company are facing serious competition both from the inner and the outer so it is in urgent need of improving seed quality and competitive power. Under such conditions, this paper made a study on the feasibility of improving the seed quality and management level of Chinese seed industry by introducing TQM, and hope the research conclusion will be useful to the development of Chinese seed industry.

中国在七十年代末期也开始引入TQM来改善我们的工业产品品质，但是在行政力量推动下的质量运动最后大多无疾而终，效果大打折扣。2000年以来，中国种子行业行政垄断被打破，市场化进程加快，种子公司面临着来自国内外激烈的竞争，亟须提高种子质量，提高自己的竞争力，在这种情况下，笔者对中国种业引入TQM来提升种子质量和管理水平的可行性进行了探讨和研究，希望本文的结论对中国种业的发展有一定的参考意义。
