对称

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。

Results show that there are components of asymmetric pressure and velocity in symmetric structure, but this portion affect normal phonation little due to its limited ratio (less than 10%).

结果表明，对称结构下存在着非对称压力和速度成分，但是由于它所占的比率有限（不超过10%），对正常发声的影响不大。

A series of novel dicationic symmetrical and asymmetrical ionic liquids based on tributylalkyl phosphonium and alkylimidazolium were synthesized.

合成了一系列含有三丁基烷基膦盐和烷基咪唑盐的对称的和不对称的双离子液体。

From optical BINOL, the chiral phosphoryl azide compound was prepared. Its application as chiral auxiliaries in the stereoselective ring-opening of meso-epoxides was examined. No obvious asymmetric induction, however, was observed.

从光学活性的联二萘酚出发合成得到了手性磷叠氮化合物，并将其应用于环氧化合物的不对称开环反应中，考察了它作为手性辅助剂在该反应中的不对称诱导效果。

Any vertex closer to the mirror plane, than the limit we set, will be placed exactly on the mirror plane.

任何与实际对称平面距离小于我们所设置的重合范围的点都将会直接放在对称平面上。

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。

A half of a symmetrical, approximately spherical object as divided by a plane of symmetry.

具有在颊舌方向上的对称面和/或近远中方向上的对称面的侧面通用外形的预制的可煅的牙冠。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
