低空分层降水和云水同步采集系统的开发和应用

笔者自行开发并研制了低空（ ＜ １ ｋｍ） 分层降水和云水采集系统，该系统成功地应用于福建省厦门市和贵州省贵阳市酸性降水来源和成因的研究中，取得了显著的成果，为探讨酸性降水来源和成因提供了有效的技术手段和支持。该系统可以在一定程度上代替航空测量，目前国内外的类似研究中没有使用该系统进行样品采集的先例，因此该系统的开发填补了国内外相关研究领域的空白     

腕足类生物壳体在沉积、成岩过程中同位素平衡问题研究

综合分析了现代腕足类生物壳体方解石中的C、O同位素特征，以及有关古生代腕足类生物壳体方解石构造和地球化学研究成果，分析结果证明：只有那些无发光性特点、无胶结和溶蚀构造特点、有较好纤维构造特点、含高Sr、Na和低Mn、Fe（Mg）的第二层腕足类生物壳体方解石的δ18O值不受成岩作用影响；而原始层和壳体中的特殊部位如铰合轴、腕骨、茎孔、交互面、肌痕等在沉积、成岩过程中与海水处于非同位素平衡状态。     

The spatial and temporal distribution of total ozone over China

In this paper the grid data of total ozone mapping spectrograph (TOMS) installed on Nimbus-7 satellite (1978 to 1994) was used and the spatial and temporal distribution of total ozone over China was analyzed. The research indicates that the Qinghai-Tibet Plateau destroyed the latitudinal distribution of total ozone of China and the low value closed center emerged over Qinghai-Tibet Plateau. Long time change trends of seasonal total ozone of Qinghai-Tibet plateau are provided. It shows that the most obvious decrease of total ozone occurs in winter (Jan.), then in summer (Jul.), the relevant slow change occurs in autumn (Oct.) and spring (Apr.).     

青岛地区大气气溶胶海洋因子贡献研究

本文对青岛地区大气气溶胶海洋因子的贡献进行了分析研究，得出以下结构：（１）复季受海洋影响要比冬季明显得多；（２）就质量浓度而言，ＩＰ（ｉｎｈａｌａｂｌｅ ｐａｒｔｉｃｌｅ）中的海盐源要高于ＴＳＰ（ｔｏｔａｌ ｓｕｓｐｅｎｄｅｄ ｐａｒｔｉｃｕｌａｔｅｓ）；（３）海洋影响的程度和离海边的距离有关。离海逾远，受海洋影响就逾小；离海连逾近，受其影响就逾大；（４）ＩＰ冬季海盐源为２％－４％，夏季为１０％－     

Analysis and improving ways for water condition in winter wheat field of dryland in subhumid areas of the loess plateau

Based on the soil moisture data from the locating experiments from 1986-1990, and using the water balance method, the water supply and demand state in the field of winter wheat, and the ways for improving water condition in dryland of subhumid by dry area of the Loess Plateau were studied. The results suggested that a low precipitation satisfying ratio of 42.9%-58.8% appears in the growing period of winter wheat, and the yield, to a great extent depends on the water that was stored in deep soil layer in the previous rainy season. The filed trial results showed that tillage in the summer fallow period,straw cover, soil moisture regulation with adequate fertilization, crop rotation and proper croppingsystem could be the efficient ways for improving the water condition,and for the exploitation and utilization of natural water resources(both precipitation and soil water) in the winter wheat field of dryland.     

总氮、总磷联合测定方法的改进

采用钼锑分光光度法测定总氮,考察了在提高温度的条件下,缩短消解时间对测定结果的影响。试验结果表明,调节氢氧化钠和过硫酸钾的用量,在同一溶液内测定总氮、总磷,并且将测定条件改为126～128℃,消解10min,其测定结果和与标准方法对照,精密度及准确度均令人满意。     

制革废水的治理

介绍了采用调节—混凝沉淀—生物接触氧化工艺处理制革生产废水工程的设计调试运行结果。从运行效果看该工程因地制宜，投资省，运行费用低，处理效果好，出水可达到排放标准。
