main outcome measurements: the capsule was manipulated in the esophagus for 10 minutes. it was easy to make the capsule turn somersaults and to angulate at the cardioesophageal junction.
independently, the present invention provides methods and mechanisms in which the chin support can angulate independently of the collar body.
独立地,本发明提供了下腭部可独立于圈体成 角度的方法和机构。
capsule subglobose, ca. 9 mm in diam. , valves slightly smooth and flat, not obviously angulate .
蒴果近球形,长约9毫米直径,裂爿稍变平静,平,不显而易见具棱。
an effective method which is simply and widely used is adopted in vernier adjustment technology for the request of angulate symmetry or turning round synchronism.
