The eigenmedes are left--hand or right--hand circular polarised wave,the dipole radiation is closely related to the chirality parameter.

结果表明：手征媒质中存在电磁模式分裂，其本征模为左、右旋圆极化波，偶极辐射性质与旋波因子密切相关。

Almost defference sets have strong relationship with binary sequences with optimal 3-level autocorrelation, which are of significant applied bachground. We constructed 2 new infinite families of almost difference sets by using cyclotomy; Perfect binary sequences and perfect binary sequences pairs are of significant theoretical value and applied background, they correspond to cycle Hadamard matrices and difference sets pairs respectively.

几乎差集与具有最优3级自相关二元序列密切相关，具有强烈的应用背景，我们借助分圆方法构造了几乎差集的两个新的无穷类；最佳二进序列和最佳二进序列偶有着重要的理论价值和应用背景，它们分别对应着循环Hadamard矩阵和差集偶。

With differential geometry knowledge, the local characters of the blade surface are analyzed. Based on researching the cylindrical cutters osculating location, the methods to calculate the osculating location of the conic cutter and the torus cutter are discussed. A method of tool path planning based on the second order osculating method is preferred.

利用微分几何学知识，分析了螺旋桨桨叶曲面的局部特征，在研究圆柱刀二阶密切法规划刀位的基础上，探讨了圆锥刀和圆环刀的二阶密切刀位计算方法，采用二阶密切法规划刀位可以显著地提高加工精度。

Results The overexpression of c-Ha-ras was closely associated with the formation and proliferation of the precancerous basophilic hepatocyte foci, while that of c-myc with the growth of the oval cell foci.

结果 c-Ha-ras和c-myc基因的过表达参与了肝癌变的全过程，其中c-Ha-ras的过表达与癌前嗜碱性肝细胞灶、c-myc基因的过表达与卵圆细胞增殖关系密切。

There is n strong association of PFO with paradoxical embolism and ischemic cerebral infarction, and reports on patients with PFO-related cryptogenic stroke after coronary artery bypass grafting and various surgical cases of heart or lung are being increasingly published in recent years.

近年来的研究发现，卵圆孔未闭的存在与反常栓塞、缺血性脑卒中的发生密切相关，与冠状动脉旁路移植术及各种心、肺手术后不明原因的卒中或猝死相关的报道日益增多。

The results show that the compressibility of cohesive soils is closely related to the grain morphology, granulometric distribution, grain packing and pore distribution.

研究表明：粘性土的压缩性与颗粒的形态、分布及排列、孔隙的分布情况密切相关；一般来说，颗粒的分布分维、定向度、圆度越小，土体的压缩性就越低，抗压性能就越好。
