1·Most spiral-shaped snail species are predominantly dextral.

大多数螺旋形的蜗牛主要是右旋的。

2·In the case of Lymnaea peregra, studies indicate that a dextral gene is expressed during egg formation.

在锥实螺的例子中，研究表明右旋基因是在卵的形成期表达的。

3·In experiments, an injection of cytoplasm from dextral eggs changes the pattern of sinistral eggs, but an injection from sinistral eggs does not influence dextral eggs.

在实验中，用取自右旋卵子的细胞质进行的注射，可改变左旋卵子的模式；用取自左旋卵子的细胞质进行的注射却不能影响到右旋卵子。

4·In experiments, an injection of cytoplasm from dextral eggs changes the pattern of sinisterly eggs, but an injection from sinisterly eggs does not influence dextral eggs.

在实验中，右旋卵子的细胞质注射改变了左旋卵子的形态，但是左旋卵子的细胞质注射不会影响到右旋卵子。

5·In the case of Lymnaea peregra, studies indicate that a dextral gene is expressed during egg formation;

在锥实螺的例子中，研究表明右旋基因是在卵的形成期表达的；

6·The main shock occurred on the dextral obduction-type fault zone and the hypocenter depth was about 15km .

汶川地震的主震发生在具有右旋性质的仰冲型断层带上，震源深度为15公里左右。

7·S-C fabrics and asymmetric rotational augens in mylonite indicate sinistral shear and locally dextral shear.

组构和不对称旋转碎斑指示以左旋剪切为主。

8·Conclusion Dextral-fosfomycin can be chiral biotransformed to levo-fosfomycin by Penicillium camemberti 2221.

结论沙门柏干酪青霉2221可手性转化右旋磷霉素为左旋磷霉素。

9·The early fault zone was reconstructed and became dextral right - step Z - type fault during dextral - slip stage.

在右行走滑改造阶段，早期左行右阶断裂带被改造为“Z”型右行右阶断裂带。

10·The ingluvies was supplied by the cranial and the ingluvies, the caudal sinistral and dextral arteries of the ingluvies.

分布于嗉囊的动脉有嗉囊左、右前动脉和嗉囊左、右后动脉。
