两侧辐射对称的

This is the first report that not only the differences of flower symmetry genes expression but also expression timings may result to zygomorphy/actinomorphy transition.

本研究首次报导不仅对称基因表现位置，甚至时间也是关键性因素，因而促成残存两侧对称的变异型辐射对称花的形成。

However, among zygomorphic Gesneriaceae species, some species have evolved from zygomorphy back to actinomorphy.

相较於辐射对称花，两侧对称花常具专一传粉者并有较高的授粉效率，故其种化速度亦常较前者来得快。

Multicellular animals, a system, both radial symmetry and bilateral symmetry of the characteristics of comb jellyfish found in animals and Anthozoa animals.

多细胞动物的一种体制，兼有辐射对称和两侧对称的特点，见于栉水母动物及珊瑚纲动物。

The metazoans in the Wenghui Biota had radiate symmetrical animals, including Porifera, Ctenophora, Cnidaria, and Trilobozoas, and bilateral symmetrical animals, including Annelida and possible Mollusca.

瓮会生物中宏体后生动物有海绵类、栉水母类、刺胞类和三叶类等两胚层辐射对称动物以及环节类和可能的软体类等三胚层两侧对称动物。

In Saintpaulia ionantha, actinomorphic peloria was raised in domesticated cultivation from the zygomorphic wild type.

然而，苦苣苔科的野生型园艺植物非洲堇(Saintpaulia ionantha， African violet)原本野生型的花是两侧对称，但在人择栽培后有反转为辐射对称的变异型出现，这给予我绝佳机会探讨在同一种植物中花部对称性转换的分子机制。

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。

Corals on both sides of a mouth trench mouth, comb jellyfish have tentacles on both sides of the body structure and the capsule show both sides of the symmetry, but other structural Jun Cheng radial arrangement.

多细胞动物的一种体制，兼有辐射对称和两侧对称的特点，见于栉水母动物及珊瑚纲动物。

Flowers perfect and hermaphroditic or occasionally unisexual, actinomorphic or zygomorphic,(2-)4(-7)-merous, axillary, in leafy spikes or racemes or solitary, or occasionally in panicles, all but Ludwigia with distinct floral tube, nectariferous within.

偶有的完全花和两性的或单性，辐射对称或者两侧对称，(2-)(-7)瓣，腋生的4，在多叶穗状花序或总状花序或单生内，萼片绿色或有色，镊合状排列。

This suggests persistent expression of SiDIV and ceasing of SiCYC1A and SiCYC1B in late peloric flower stage may generate the actinomorphic flower.

综此推测，变异型的花发育成辐射对称可能是由於开花晚期时SiCYC表现量下降及SiDIV持续表现，造成花发育后期两侧对称性的无法继续维持，而成了辐射对称花形式。

In view of the development about the certain airborne radar antenna array,considering the structural features of antenna array,analyse the cruces in manufacturing of feed cavity and radiant plate,and present the corresponding solution by mainly dealing with precise positioning style,delicate clamp design,error distribution and compensation method,high speed machining technology design,machining simulation and program optimizing.

某机载雷达平面裂缝阵列天线的单面阵如图1所示。该面阵布置多路裂缝线源，共分布384处长度各不相同的辐射裂缝，每一路线源均由脊型波导口单独馈电。面阵由辐射板和馈电腔两个零件组成，采用整体钎焊成形。线源结构为非对称单脊共线形式，即在普通单脊波导的两侧与辐射裂缝相对应的位置上布置不对称的凹台。
