In the case of the same sensor number,this method which adopts appropriate array geometry arrangement can improve the resolvability of DOA estimation more obviously than the uniform linear array.

在阵元数一定的情况下，该方法可使阵列的方位分辨率较之均匀线阵有较大的改善，而且还克服了一般稀布线阵方位估计模糊和去相关能力差的缺点，成功地将空间平滑MUSIC这一经典方法用于非等矩阵。

As a result, some valuable taxonomicmethods, criteria and our viewpoints were concluded. The morphology ofthe sporus is the main identical base at species level, which include thecharacters of the shape, size, colour, septate and ornament of the wall etc,and some sporus with distinct variable are also useful at genus level.

孢子的特征(包括形状、大小、颜色、隔膜数和表面纹饰等)是种级分类的主要依据，一些形态差异较大的孢子可作为属的划分标准；其次，分生孢子梗的形态特征、产孢细胞的延伸方式及产孢方式也是主要的鉴别依据，对属级水平上该真菌的鉴别有重要意义；另外，培养特征及产孢表型可作为分类鉴定的必要、有益补充。

The results show that this kind of roughening elements can possess a wide range of roughness, and the hydraulic resistance decreases with the increase of space between roughness elements, but reduces slowly to a constant, and that flow enters into the turbulently rough zone when Reynolds number reaches about 3 500, in which the hydraulic resistance decreases with increase of relative submergence degree, reducing slowly to a constant too.

通过水槽试验对Y型加糙体阻力特性进行了深入研究。研究结果表明：其糙率具有一个较大的调整范围，且随着加糙间距的增加水力阻力减小，减小的幅度越来越小，最后基本不变；雷诺数在3 500左右水流进入阻力平方区，进入阻力平方区后，随着相对淹没度的增大水力阻力减小，最后达一定值。

The rising and deformation of two identical spherical and deformational bubbles moving side by side or in a line in a viscous fluid is studied numerically. The interaction between two bubbles with a wide range of Reynolds number and separation distance is studied.

4对水平和上下放置的球形气泡和变形较大的两个气泡在浮力作用下的上升及变形过程进行了模拟，分析了气泡间距与Re数之间的关系，揭示了气泡融合过程中上升速度的降低与反弹现象。

The algorithm uses the six-dimensional Legendre orthogonal coefficients to form a vector for describing the shape of glottal flow derivative.

该方法将声门波导数波形在6维正交勒让德坐标系中的投影构成了描述其形状的特征矢量，并采用基于GMM的概率分类加权转换算法，使每个特征矢量的转换规则可由多个类所对应的规则的线性加权组合得到，可以使转换性能得到较大的提高。

The central ring appears to represent the narrow waist of an hourglass-shaped puff of gas, and the larger rings are the edges of two teardrop-shaped lobes, evidently created by the star a few tens of thousands of years before it exploded.

中央的环看来是沙漏状云气的细腰，而较大的圈圈则明显是在爆炸前数万年，该恒星就已经喷出的两片泪珠状云瓣的边缘。

An apparatus made by our lab is used for direct measurement of torque of yarns. The torque-twist relation curves, torque-relaxation behavior of several kinds of yarns at room temperature and heat-setting temperature are given. After analyzing the difference of different yarn torque it can be found that the special structures of composite yarns made of polyester filament and wool staple fibers mainly cause the high residual torque.

应用自行研制的直接测量纱线扭矩装置，这里测试数种纱线的扭矩-捻度关系曲线及其在常温和热状态下的扭应力松弛关系曲线，分析相同捻度下各种纱线扭矩差异的根源，发现涤长丝与毛短纤复合纱线的特殊结构是造成复合纱线残余扭矩较大的主要原因。

It was displayed that there were on e to seven insertion loci and one to ten copies of transgene in different transf ormants.

转基因拷贝数的多少与其表达和沉默不存在必然的联系。相同整合模式的转基因事件中基因的表达存在较大的差异。
