X ray signs presented as follows: The tumor containing more fibre tissues showed an expansive transparent area of a single loculus or multiple loculi, within which a streak like interosseous crest and a calcified patch could be seen;

On the end of the worm, disc-like haptor is composed of 1 central loculus, 8 radial small loculi, 56 marginal papillae and tri-lobed finger-like projections.

后端圆盘状后吸器由1个中央室、8个辐射小室、56个边缘乳突及三叉形指状突组成。

Ethylene in the ovary loculi begins to be detected in middle of August, and later, the ethylene concentration increases rapidly.

8月中旬，乙烯开始在子房室内积累，且浓度不断增加。
