两对称

And in the second part, we consider the following four inverse eigenproblems: the reconstruction of normal five-diagonal matrix by two or three ordered eigenvalues and cor...

第二个部分则讨论四类矩阵逆特征值问题：在考虑给定的两个或三个特征值次序的情况下构造唯一的规范五对角线矩阵：由三个给定的特征值和相应特征向量来构造唯一的实对称三对角线矩阵和不可约实对称三对角线矩阵。

Firstly, based on the basic theory of GRIN optics the optical effects of the spherical symmetry GRIN micro-sphere lens were analyzed systematically. Firstly, based on the basic theory of GRIN optics the optical effects of the spherical symmetry GRIN micro-sphere lens were analyzed systematically.

本工作从梯度折射率介质光学的基本理论出发，对球对称GRIN微球透镜的光学性能进行了系统的分析；研究了用球对称GRIN微球制作回归反射材料的可能；进而选择两种聚合物单体，采用悬浮扩散共聚法，研究制备了较大粒径的聚合物梯度折射率微球透镜。

The other technique was so called "Constraint Induced Movement Technique" to apply a shoe lift or wedge under the stronger limb, providing a compelled shift of the body weight onto the paretic limb to increased ability of weight bearing. This technique helps patients achieving symmetry of stance and weight bearing and overcoming the learned disuse mechanism. Therefore, the purpose of this study was to investigate the effect of 5° lateral wedge on non-paretic limb improving symmetry of stance and weight bearing for stroke patients.

另外有一种技巧和方法为强迫诱发运动，在健侧使用鞋垫，强迫病患把身体的重心移到患侧去，藉此增加患侧脚承载的能力，研究有使用加高型或外侧楔型的鞋垫，目的都是要使中风的病患能有较对称的站姿及两脚有较对称的重量承载比例，如此一来可以强迫患侧使用更多，进而克服学习废用机制，上述研究多为急性期病患的探讨且多是观察当下的影响及效果，因此我们想利用外侧楔型鞋垫的帮助，藉由在健侧脚较长时间的穿著，看看对於慢性中风病患的站姿控制所造成的影响。

Moreover, the expression of SiCYC in dorsal part of flowers in peloria may explain why the peloria retains traced zygomorphic syndrome (the dorsal and lateral stamens are smaller than the ventral ones).

另外，SiCYC在两种对称型的背侧花瓣上都有表现，可以从辐射对称变异型花朵中背侧及两侧雄蕊略小於腹侧雄蕊的形态观察中找到佐证，显示变异型花朵仍有残存的两侧对称性存在。

Radially symmetrical, so that a line drawn through the middle of the structure along any plane will produce a mirror image on either side.

辐射对称 Actinomorphous 辐射状对称，通过结构中央的任一平面都能将其分成互为镜像的两部分。

Bilaterally symmetrical, so that a line drawn through the middle of the structure along only one plane will produce a mirror image on either side.

左右对称的 Zygomorphous 两侧对称，仅在，通过结构中央仅有一个平面能将其分成互为镜像的两部分。

Protoplast fusion can circumvent reproductive barriers facing citrus, such as polyembryony and female and/or male sterility, and paves way for citrus cultivar improvement.

柑橘原生质体融合主要采用"叶肉原生质体+胚性愈伤组织原生质体"和"胚性愈伤组织原生质体+胚性愈伤组织原生质体"两种模式，融合方式主要有对称和非对称融合。

The recognizability of the face is then defined as the function of the face size and the relative locations of eyes and mouth.

第四个部份，以两眼和嘴巴形成的三角形、方向的对称度、区域灰阶值的对称程度，来区分人脸的转向为三大类：正脸、有转动的脸和非正脸。

The effects of the stiffness and location of the connection to the seismic response of the structures are analyzed.

对对称双塔连体结构和非对称双塔连体结构的动力反应进行了对比研究，分析了连体设置与否对这两种结构的地震反应的影响。

The introduction of local supersymmetry on worldsheet results in the Ramond-Neveu-Schwarz model, and global supersymmetry in the ten-dimensional spacetime directly yields the Green-Schwarz superstring. The Green-Schwarz superstring theory is a covariant theory.

这两种描述方式的不同点是：Ramond-Neveu-Schwarz超弦理论在超弦的世界面引入局域的超对称，Green-Schwarz超弦理论是在十维时空中直接引入超对称，它是一个协变的理论。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
