On the basis of foreign research achievements, two kinds of domestic cold-formed steel sections are used as the parent materials to design Rosette-joints. Different styles of joint and various influencing factors (including form of hole, aperture, and the edge distance from the center of joint to the edge of the sheet) are taken into account, and four series of test specimens are schemed out. A series of axial-tension tests on all test specimens are carried out to investigate the shear strength of every rosette-joints.

本文结合国外的研究成果，采用我国常用的两种较大尺寸的冷成型钢型材作为母材来设计插座式连接，考虑了节点的不同形式以及影响节点承载力的各种因素(包括孔形、孔径、端距等)，设计出四组不同形式的节点试件，并对各组试件进行轴向拉伸试验来考察各种类型插座式节点的抗剪承载性能。

When one element of an N-element array is aberrated, the most sensitive aberration is Piston error, and then the sensitive aberrations are element defocus, tilt, spherical aberration, coma and astigmatism. As for four aperture system, the influence of Piston error is 2 times larger than that of defocus, and 4 times larger than that of astigmatism.

在合成孔径成像系统单个子孔径存在像差的情况下，Piston误差对系统的影响最大，其次是离焦误差、倾斜误差、球差、彗差和像散，对于四孔径系统，Piston误差对系统的影响几乎是离焦误差的2倍，像散的4倍。

Research on uncalibrated self-adaptive 3D reconstruction algorithm. For different or varible scene, the intrinsic and extrinsic parameters of camera may be required to modify, for example, change focus length for different depths, change aperture size for different light intensity, change the skew angle between optics axises of camera and projector for ideal viewfield, etc.

对于不同的或变化的场景，摄像机的内部参数与外部参数可能需要调整，如对于不同的光强需要调整光圈的大小，对于不同的景深需要调整焦距的长短，甚至需要调整摄像机的光轴与编码投影系统的光轴之间的倾角，以使采样范围正好落在被照明的范围内。

The results show that,in the static pressure tank,the air velocity decreased and the pressure distribution was uniform gradually in the corner between the plates and clapboards with the increase in the aperture of the perforated plates.Moreover,there was Coanda effect around the freezing food in the freezing area and the food temperature decreased from the inlet to the outlet of the freezing area.

通过改变位于冻品上下方的均风孔板开孔率得出：在静压箱内，随着出口开孔率的增大，风速逐渐减小，并且在由孔板和隔板间形成的局部区域内，压力分布逐渐趋于均匀；在冻结区内，通过速度场的模拟，从数值计算的角度验证了冷风在冻品表面产生的柯恩达效应。

Pollen morphology is remarkably diverse, particularly in aperture and exine ornamentation.

花粉形态特征，特别是在萌发孔和外壁纹饰上表现出多样化。

However, differences exist in pollen size, aperture, exine thickness and ornamentation.

但在花粉大小、萌发孔形状、外壁厚度以及表面纹饰等方面存在差异。

Pollen descriptions are given for 28 types based on pollen shape,aperture numbers and arrangement, and the ornamentation of exine.

根据花粉的萌发孔、外壁结构、外壁纹饰、形状及大小的演化趋势，讨论了各类型花粉的亲缘关系，构建了它们的系统演化路线图谱。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
