查询词典 focal length

Experimental results and values in theory were accordant well. Experimental results showed that the radius of focal spot would increase with the longer focal length, and focal depth would decrease with higher order of FZPs.

实验还发现，聚焦的焦斑半径会随着焦距的长度而增大，而聚焦深度则随着分形波带片的阶次的升高而减小，同时还对比了分形波带片和常规波带片的焦距调节方式和精度，理论研究表明分形波带片的调节焦距的方式具有更高的调节精度。

As to Balilla erect panicle type,(the same subject for the following 11-16), the curvature of panicle neck had a very significantly positive correlation with panicle length, neck panicle length, neck panicle internode length, the secondary internode length, leaf length and leaf sheath length, and had an opposite correlation with leaf width and density of seed setting.

对巴利拉型直立穗型品种来说（以下11～16同此所指），颈穗弯曲度与穗长、穗颈长、穗颈节间长、倒2节间长、叶长、叶鞘长呈极显著正相关（倒3叶呈显著正相关），与叶宽、着粒密度呈极显著负相关。

As to Balilla erect panicle type,(the same subject for the following 11-16), the curvature of panicle neck had a very significantly positive correlation with panicle length, neck panicle length, neck panicle internode length, the secondary internode length, leaf length and leaf sheath length, and had an opposite correlation with leaf width and density of seed setting.

来自吉林的直立穗型品系Z1和来自黑龙江的直立穗型品种龙交91060—2与巴利拉型直立穗型品种的直立穗其因分属于3个不同的位点，各自位于3对同源染色体上，彼此遵循基因的自由重组和独立分配规律。Z1由1对显性主效核基因控制，龙交91061—2由1对隐性主效核基因控制。3个直立穗型基因位点可能具有累加效应，直立穗型效应位点越多，则颈穗弯曲度越小，穗的直立性越强。

The results of the meristic characters about the two species indicate that body length/body depth, body length/head length, head length/snout length and head length/eye diameter exhibited wider ranges compare with the previous recordations.

石鲽的体长L(下标 B8与体高D(下标 Ba之间的关系D=0.3250L+2.3263(r=0.7329)；体质量W(下标 Bs，g和体长L(下标 Bs，cm之间的关系W=0.2559(上标 2.1238) L (r=0.8138)。这两种鱼的可量可比性状：体长／体高、体长／头长、头长／吻长和头长／眼径的比值范围比原来研究记载的更加宽泛。

Measuring the focal length of concave lens using collimator;2. The relation between the focal length of a concave lens and its reflective image properties is analysed and deduced.

本文分析推导了透镜的凹面反射成像与凹透镜焦距的关系，介绍了利用此关系较方便地测量凹透镜焦距的方法。

They have a focal length, and where an image is formed depends on a combination of the focal length and the distance between the object and the lens.

透镜有焦距，而影像形成的位置，取决于焦距及物体与透镜距离的组合。

The influence of the focal length in focal lens on the bottle radius and bottle length is discussed.

讨论了聚焦透镜的焦距f对径向暗域最大尺寸及轴上暗域长度的影响。

Since the focal length is a purely paraxial size, numerous sources of error exist during the focal length

因为焦距是一个近轴尺寸，在实际物镜测量过程中存在许多误差源。

At the same time, the development of the lens to the series, a few millimeters from the focal length of the fisheye lens to the focal length of 2 meters of super-long telephoto, and with perspective adjustment, zoom away from the emblem, such as night-vision camera lens.

同时，镜头向系列化发展，由焦距几毫米的鱼眼镜头到焦距长达2米的超摄远镜头，并有了透视调整、变焦徽距、夜视等摄影镜头。

With the modified method, the focal field of WSRT telescope was computed. Based on the result, the dense focal plane array was designed for the telescope. The weights of focal plane array were given by the conjugate field method and the far fields of WSRT were computed.

采用改进的算法计算了WSRT望远镜的焦面场，并根据计算结果设计了WSRT望远镜的致密焦面阵结构；用共轭匹配法对阵列单元加权、计算相应的远场方向图，并与采用单个馈源时的远场方向图作比较。
