Phébus-FP: Results and significance for plant safety in Switzerland

Phébus-FP is a multi-national collaborative programme comprising four integral and one debris bed melting and fission product release experiments. The integral experiments simulate the heat-up, degradation and fission product release and transport, thermal hydraulic response, aerosol behaviour and iodine chemistry in the containment. The total programme, including interpretation effort, runs from 1993 to ca. 2007. The experiments demonstrated new characteristics of core degradation, fission product and iodine chemistry and accident integral behaviour. PSI has participated extensively through planning support, interpretation of data from the experiments and analyses of the results to establish confidence in the models being used for plant application. A significant part of the PSI effort was performed to interpret the significance of silver iodide as an effective retention agent under typical reactor conditions. The conclusions are of an interim nature, since the data reduction and interpretation are not yet complete. The significance of the Phébus results for plant safety will be fully realised only after successful benchmarking of the computer codes against Phébus, and application to plant sequences. Such work remains in progress within the Phébus project and in various national programmes.

甲烷预混火焰自适应化学理论模拟及其与试验的比较

通常实际湍流火焰中不同燃烧区域的化学反应特性大不相同，且辐射在热传递过程中扮演了非常重要的角色。该文采用辐射模型离散坐标DO法来完善自适应化学理论。基于详细化学反应机理，在不同区域使用不同的简化反应模型来进行化学项的求解。针对甲烷／空气预混火焰，该文对其燃烧行为进行了合理的重现，考虑辐射模型之后的计算结果与试验结果吻合得更好。

聚噻吩吸收光谱性质的理论研究

用密度泛函理论B3LYP方法,在6-31G基组水平下,选用GAUSSIAN03程序,对聚噻吩未掺杂体系及其掺杂体系(包含6个噻吩环)进行了计算.引用极子和双极子模型并模拟以Cl作为具体P型掺杂剂,分析了未掺杂体系、极子掺杂体系、双极子掺杂体系的吸收光谱性质.对实验得出的吸收光谱性质进行理论解释,得出了与实验观察规律性一致的结果.初步探讨了形成双极子构型时两个掺杂剂原子与聚噻吩链接近的方式-掺杂剂离子应该是在聚噻吩链的同一侧来接近聚噻吩链的.     

双光纤方向耦合器组成的梳状滤波器

提出了一种由双光纤定向耦合器组成的光学梳状滤波器,由传输矩阵法推导出了该模型输出光谱与有关参数之间关系的数学表达式,对决定滤波器输出光谱特性及其规律的相关参数进行了详细讨论。模拟与分析表明,在一定条件下,输出光谱半宽度?λ1/2、输出消光比以及波长隔离度等仅与耦合器的耦合比系数有关,具有明显的法布里-珀罗腔多光束干涉的特点,耦合比系数非常类似法布里-珀罗腔中的反射率,通过控制耦合比系数可以调节滤波器的输出光谱半宽度?λ1/2、输出消光比、波长隔离度,已适用不同的应用要求。     

1999年GEMS／Food分析质量保证考核

为分析1999年度GEMS/Food农药残留分析质量保证考核提供的试样,通过检索归纳文献资料对试样中可能有的5类32种农药设计了整体实验方案,并根据实际试样分析中遇到的问题加以改进,最终依现有的仪器设备条件对考核试样建立了一套可行的检测和确证方法。在全球69个实验室中,我所报告的7项结果中有4项结果排名第二位,全部结果均在±1Z范围内,远高于统计报告中±2Z范围内即为合格数据的要求。
