After careful study the soil samples of various landform and different land use the 〓Cs reference inventory is 2200 Bq m〓 of study area.

通过分析采集的研究区不同地貌形态和多种土地利用方式的土壤样品，确定研究区的〓Cs背景值为2200 Bq m〓。

The volume of radon chamber is 4 m3, the range of radon concentration is 370~20 000 Bq/m3, and the relative expanded uncertainty of measurement results is no more than 5.8%. The whole testing system can verify/calibrate the radon monitor and study on the radioactive aerosol of radon decay product.

装置氡室体积为4 m3，氡浓度测量范围为370~20 000 Bq/m3，氡浓度值测量结果的相对扩展不确定度不超过5.8%，可用于测氡仪器的检定校准和氡子体放射性气溶胶的实验研究。

The investigation has declared that the fuel injection with BQ fuel pump had higher injection pressure, bigger fuel supply rate and shouter fuel supply duration, which would cause the fuel injection quantity and the fule-air mixture to increase during ignition delay period, the pre-mixed combustion to become acutely, and finally result in increased power levels of noise.

研究表明，装配BQ喷油泵，喷油系统的喷油压力较高，供油速率较大和供油持续时间缩短，使得滞燃期的喷油量增加，滞燃期内形成的可燃混合较多，预混燃烧剧烈，导致整机噪声声功率级增加。

By superfusion of ET-1,the hypoxia-induced decrease in RPF was remarkably potentiated and the occurrence of pacemaker arrest was shifted to an earlier time. The h3,poxia-induced effects could be effectively attenuated after pretreatment with BQ-123,implying the role of endogenous ET-1 release in hypoxia-induced effects.

ET-1可显著加重缺氧所致的RPF降低，使起搏细胞停跳时间前移；而以ET*受体阻断剂BQ-123预处理窦房结标本后，则能有效地缓解缺氧对起搏细胞的效应，提示内源性ET-1的释放在缺氧效应中的作用。

Including the force BQ ao mixture and the force seepage cleaning media, can eliminate the bathtub to soak the circle, the soap filthily effectively, the boiler scale and so on.

含强力BQ型鳌合剂和强力渗透除垢剂，能有效清除浴缸渍圈，皂垢，水垢等。

Then the cyclocarbonylation of propargylic alcohols under the catalysis of Pd 〓 with CuBr〓 and BQ was studied. Due to the high activity the yields of -α-bromoalkylidene-β-lactones were lower than that of -α-chloroalkylidene-β-lactones while the coupling reaction of -α-bromoalkylidene-β-1actones (i. e. Sonogashira and Suzuki coupling reaction) was quite smooth to afford the products in high yields.

接着我们研究了炔丙醇在Pd〓-CuBr〓-BQ催化体系下的羰基插入环化反应，由于-α-溴代亚烷基-β-内酯环化合物的活性高于-α-氯代亚烷基-β-内酯环化合物，导致反应收率偏低，而同样基于此原因，-α-溴代亚烷基-β-内酯环化合物的偶联反应进行得很顺利，而且收率很高。

The 137Cs inventory was 1966.99 Bq/m^2 in the watershed. Special activities of 137Cs were different in plough layers under different land uses.

研究结果表明，流域137Cs背景值为1966.99 Bq/m^2，流域内不同土地利用方式下土壤137Cs比活度不同，且有比较明显的137Cs比活度分异。

2The rock mass quality was assessed based on the data obtained from exploration adits with the methods of engineering geological classification for surrounding rock mass, BQ, RMR and Q-system successively. And then the correlations between the assessment results of different methods were discussed.

基于勘探平硐获取的资料，运用&围岩工程地质分类法&、BQ法、RMR法和Q系统法进行了地下厂区岩体质量评价；讨论了四种不同方法评价结果之间的相关性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
