"中国模式"在实现经济增长方面确实显现了一定的优势,但也付出了沉重的代价,如极化效应、短期行为、贫富悬殊、公共服务滞后、社会保障不足、社会抗议运动等.而且在目前的发
As molecular targets continue to be identified and more targeted inhibitors are developed for personalized treatment of non-small cell lung cancer(NSCLC), multi
We report the case of a 67-year-old female who presented with a large renal mass. Gross examination of the nephrectomy specimen demonstrated a 6-cm renal mass t
研究了堆肥生物滤塔和污泥生物滤塔对含氨气体的处理能力。研究表明,在反应器运行的210 d内,两种生物滤塔处理含氨气体的效果均较好。当两生物滤塔达到稳态运行后,对浓度190 mg/m3时,去除率降到了50%左右。长期运行以及高负荷条件下,两生物滤塔均出现了失活现象,这可能与填料性质发生改变有关,而产物积累则是导致填料性质改变的因素之一。分析填料中各种形态氮的浓度发现,氨在反应器中的转化以硝...
