喷灌条件下土壤水分、硝态氮空间变异特征研究：应用地统计学理论，以半方差函数为工具分析不同灌溉制度下，土壤含水率(0～60cm)和土壤中硝态氮在相应深度的空间分布，用各类模型拟合半方差图，在此基础上应用普通克立格技术估算未知点的土壤含水率，使用最优内插值法绘制土壤含水率和硝态氮在田间的空间分布等值线图。

To improve the simulation accuracy and to make the increment of computation amount the smallest, the quantitative comparison was used to compare the effect of incident direction and difference accuracy on numerical dispersion with the changing of the ratio of horizontal and vertical gird. The results show that the rectangular grid is better than square mesh in suppressing dispersion and can avoid the low computational efficiency caused by high-order difference.

为提高模拟精度，同时又尽可能减少计算量，采用定量分析的方法，对比分析了横纵网格比变化时入射方向和差分精度等因素对数值频散的影响，分析结果表明，矩形网格较之正方形网格能更好地压制频散，同时可以避免高阶差分导致的低计算效率。

Results show that with the increase of the apparent gas velocity in the riser,there is little change in negative pressure gradient in the standpipe.

结果表明：随着提升管内表观气速的增加，立管内的负压差梯度变化不大；而随着系统循环量的增加，立管内的负压差梯度以及滑移速度均增大；随着加入热解室内松动气量的增加，立管内尤其是立管上部的压力也随之增大，热解室内无论是移动床流动还是流态化流动均对立管的稳定性影响不大；但当热解室内的压力超过某一值时，立管内的料封很快被破坏，导致系统无法运行。

According to the samples of Ommastrephes bartramii collected by Chinese squid jigging vessels during July to October in 2007 in the northwest Pacific Ocean, the ratio of statolith maximum width to total length, as an indicator of shape change of statolith, was analyzed under different sex maturitiy stages and individual sizes using the method of ANOVA and LSD.

本文根据2007年7～10月我国鱿钓船在西北太平洋海域连续采集的柔鱼样本，以耳石最大宽度MW与其总长TSL之比作为其耳石形态变化的指标，利用方差分析和最小显著差法研究了性成熟和个体大小对耳石形态的影响。

讨 论的模型为两级的串行生产线，利用结构随机矩阵理论和马氏过程的协方差结构，给出了在一个给定时间区间内系统生产成品数方差的有效算法。

On the ground that the covariance between the disturbing gravity field elements is not isotropic, the covariance matrix has a complicated structure (its submatrix being not repetitive Toeplitz matrix) and thus its degree cannot be degraded with transformation matrix method, so it cannot be put into practice. So far, the application of least squares collocation to the modeling and data processing of the horizontal disturbing gravity field observations has not been found in literature.

由于水平扰动场元之间的协方差并非各向同性，导致协方差矩阵结构复杂(子矩阵不是 Toeplitz 循环阵)，不能利用变换矩阵将其降阶，无法付诸实践，迄今尚无最小二乘配置理论应用于水平扰动场元观测量的模型化公式和数据处理方法。
