A precondition was that the stand diameter grew 2 cm every year. For Evodia meliaefolia community, in the competitive living space by close cover stand, the ratio remained low for ten years with little fluctuation. However, in the unlimited open space, the ratio reached two peak values, with the first appearing in the eighth year, and the second in the eleventh year.

在假设了楝叶吴茱萸和油茶每年胸径生长2 cm的前提下，楝叶吴茱萸冠层总面积变化规律是：在郁闭林分被抑制的生长空间里，楝叶吴茱萸冠层总面积扩散速率可以长达10多年基本维持在一个很低的水平下，而且基本没有太大的变化；在获得充分开阔的生长空间里，楝叶吴茱萸冠层总面积扩散速率出现两个增长高峰，一个出现在第八年，一个出现在第十一年。

在25℃和0.1MPa的压差条件下，经24h合成的膜的完整性最好，H〓／N〓，H〓／CO和〓的理想选择性分别达到7.33，10.11和18.24，显著高于相应的努森扩散值3.74，3.74和4.69，表明大部分气体分子是在分子筛孔道中进行扩散。

At 〓 sites. 8. No matter in what type of zeolite (4A, NaY or ZSM-5), the diffusivity vs. adsorption amount curve of water consists of two noncontinuous lines , which will become one at last with the increase of pre-adsorbed water amount.

对水的扩散进行研究，发现不论哪种分子筛(NaY、4A或NaZSM-5)，水的扩散系数-吸附量曲线均由不连续的两段组成，随分子筛含水量的增加，最后变为一条连续性的曲线。

The coupled model is more sensitive to phytoplankton maximum growth rate, respiration rate, death rate and zooplankton grazing rate, while other parameters such as half saturation constants and remineralization rate are insensitive ones.

虽然，从表面上来看，模型对垂向扩散系数的敏感度不大，但由于目前的湍封闭模型，尚不能很好地刻画扩散系数复杂的时间变化，这势必对生态系统的模拟有着较强的不确定性。

The behaviour of oxygen in the reoxidation process was investigated by an oxygen coulometry.

结果表明；氧流量计在升温阶段检测到三个不同行为的吸氧峰，峰Ⅰ（起始温度-250℃）为氧空位的填充过程；峰Ⅱ（起始温度-800℃）和峰Ⅲ（起始温度-1250℃）为还原相的氧化过程，具体来说，峰Ⅱ是通过晶界扩散提供氧使靠近晶界附近的区域被氧化；而峰Ⅲ是由晶格扩散过程控制，氧化过程从晶界逐渐向晶粒内部区域扩展，并伴随着富Ti的Ba6Ti17O40相的沉淀。

The XRD patterns showed that the major peaks are at 18.80°, 15.20°, 33.85°, 23.65° and 24.02°, respectively, which are in very good agreement with the values of lanthanum potassium hexacyanoferrate tetrahydrate, further confirms that the compound obtained by the electrochemistry is a crystal of LaKFe〓·4H〓O.

峰电流与扫描速率的平方根在10∽750mV/s的范围内呈线性关系，表现出扩散控制的特征；在此基础上，计算了铁氰化镧在铂电极表面的浓度和钾离子在膜中的扩散系数。
