求取发动机气缸内湍流参数的不同数据处理方法的研究

应用３种湍流参数计算方法对倒倒拖工况下ＴＹ１１００发动机缸内湍流参数进行了计算，通过计算了自相关系数，标准一维能谱密度，Ｔａｙｌｏｒ微分时间尺度，对３种数值处理方法进行了比较，并研究一平均“时窗”宽度，相关窗宽度对计算结果的影响。     

采用共生遗传算法的模糊控制器设计方法

为解决模糊控制器自动优化设计中对结构和参数的学习和寻优搜索缓慢 ,以及模糊规则基维数爆炸问题 ,采用共生进化遗传算法结合分级模糊建模的思想进行模糊控制器自动设计。提出了模糊规则分类形成子种群 ,多种群并行进化的遗传算法。用这种方法可以同时设计模糊控制器的结构和参数 ,极大地减小编码规模 ,提高搜索速度。对车 杆平衡系统的控制仿真实验表明 ,该方法寻优搜索速度快 ,设计出的控制器控制效果很好。     

Oxytoxins,bioactive molecules produced by the marine opisthobranch molluscOxynoe olivacea from a diet-derived precursor

Summary The ethereal extract of the mucous secretion from the opisthobranch molluscOxynoe olivacea was examined and found to contain two novel ichthyotoxic compounds, named oxytoxin 1 and 2 (1, 2). The structures of1 and2 are closely related to the metabolites previously isolated from the algaCaulerpa prolifera. The activity of the most stable compound was studied in order to investigate the possibility, of a further biological role for these metabolites, which represent an uncommon example of bioactive molecules produced in vivo from a dietary precursor.

Absorption and translocation of tetrachlorodibenzo-p-dioxine by plants from polluted soil

Summary Measurements were made of contamination of plants grown in soil polluted with tetrachlorodibenzo-p-dioxine. Findings show that the pollutant is absorbed and translocated by the plants studied and suggest that the pollutant may be eliminated in the course of time.Acknowledgment. This research was sponsored by the Regional Government of Lombardy, Italy. The authors would like to thank Prof. Marrè for his continuous interest and for the fruitful discussion.     

角动量沿任意轴方向的投影的本征态

本首先用表象理论讨论了在任意l情况下求Lx和Ly的本征态的方法，接着用群表示论讨论了角动量沿任意轴的投影的本征态，而将Lx,Ly和Lx的本征态之间的关系作为其特殊情形来处理，并给出了相应的表达式。     

Influence de différents types de diurèse sur l'excrétion rénale de l'urée étudiée chez le rat, à l'aide des microponctions rénales

Summary The renal tubular fate of urea, as studied in the rat by free-flow micropunctures of cortical tubules, is shown to vary with different types of diuresis (urea overloading, iso- or hypertonic saline diuresis). Under certain experimental conditions, the renal tubular handling of urea appears to differ in the cortical and the juxtamedullary nephrons.
