The breeding values of 12 dairy bull, were evaluated by BLUP method, and the parameters μ, h_i, g_i, S_(jk were obtained by using computer. Comparing this evaluation with thnt of not using relationship matrix, there are some difference between them. In the calculation, A~(1-)should be added to the elements of bull, effect on the diagonal of matrix.

本文以南京市12头乳用种公牛(其中引进上海市6头、合肥市1头的冻精)为实例,应用公牛间有亲缘关系的BLUP法估计其育种值,电算求得参数μ、h_i、g_i、S_(jk,按育种值排列优劣名次,并与不加入公牛间亲缘关系的结果进行比较,发现两法间略有差异,其计算方法在矩阵对角线的公牛效应元素上加A~(1-)(即公牛间亲缘关系的逆阵)即可。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差,常因噪声因素引起边缘信息缺失导致同相轴提取不连续,本文采用中值滤波并对Sobel算子进行改进,对地震剖面图进行预处理,结合均方差自动确定阈值并进行异常检测,提取完整同相轴。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise. In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection. Firstly, the median filter and improved Sobel method are used to preprocess seismic section images. Secondly, the threshold value is determined automatically based on variance to detect abnormal information. Finally, the complete cophasal axes are extracted after a post-processing.

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.

得到如下结论:(1)相同的吸湿性,在30%PVF(颗粒体积分数:Particle volume fraction,PVF)前增加PVF,层间脱胶损伤值显著增加;此后损伤值的增加趋于平缓;(2)保持层间强度和PVF不变,层间脱胶损伤随吸湿率的增加而接近线性增加;(3)FCC(面心立方:Face-centred cubic,FCC)模型层间脱胶损伤的预测结果和实验数据基本吻合;同时此模型可以用于预测牙齿填充材料三点弯曲实验的临界载荷。4、建立理想牙齿修复结构,利用有限元方法研究了同时考虑聚合收缩和吸湿膨胀耦合作用下的填充修复材料和粘结界面层材料性能对牙齿修复结构的力学行为的影响,得到如下结论:(1)低弹性模量的牙齿填充修复材料能限制天然牙组织的位移,但天然牙组织的位移与粘结界面层的弹性模量无关。
