Fruit ovoid, slightly dorsally compressed, constricted at the commissure; dorsal and intermediate ribs filiform, lateral ribs obscure, surface glabrous or pilose; vittae 1–2 or 3–6 in each furrow, 2 or 4–8 on commissure.

果卵球形，在合生面背压扁，缢缩的稍；背侧和中间棱丝状的，侧棱不明显，表面无毛或具柔毛；油管1-2或者3-6在每棱槽，2或者4-8在合生面上。

When fiber Bragg grating is pressed by local transverse force, the reflection spectra are independent of the applied length. The wavelength of split point is periodical and linearly proportinal to the applied force. And the reflectivity of split point is approximately hyperbolically tangential versus the applied position.

研究表明，当FBG局部横向受力时，受压长度对反射光谱无影响，反射光谱分裂点的波长与横向作用力呈线性正比关系并具有周期性，分裂点反射率与受力位置的关系为近似双曲正切关系。

To reduce the happening of disease of low oxygen blood after art of lavement of high capacity complete lung, my courtyard at 2006~2008 year will not have achieve pressing aerate after applying Yu Darong to measure art of complete lung lavement, obtained satisfactory result, report as follows now.
