皱边

Usually, did not press the side turn the slab for of molding tool primarily used foring pulling the deep shallow spare parts or can't producing some familiarly shriveling.

通常，没有压边圈的模具主要用于拉深较浅的零件或不会产生一些常见起皱的厚板料。

It is suggested that the wrinkling is due to the large unsupported area at the draw wall during the stamping process, also, the side length of the punch head and the die cavity opening are different owing to the die gap.

它暗示起皱是由于拉伸过程中存在大的无支持区域，而且，冲子头部的边长和模腔的打开也由于模具间隙而不同。

Culms ca. 8 m, ca. 2.5 cm in diam.; internodes dull purple-green, becoming green with lower internodes tinged purple, to 35 cm, initially white powdery; wall ca. 5 mm thick; nodal ridge slightly elevated, as prominent as sheath scar; intranode ca. 5 mm. Culm sheaths pale red-brown, sometimes tinged green, sparsely to densely speckled, dark brown and glabrous along margins, sparsely strigose; auricles and oral setae well developed, purple; ligule purple, truncate to arcuate, short but broad, margin fringed with purple-tinged cilia; blade reflexed, purple to green, crinkled.

Culm sheaths yellow-green or pale red-brown, becoming straw-colored, with variably sized brown spots, base edged with white pubescence; auricles and oral setae absent; ligule yellow-green, truncate or weakly convex at apex, very short, 1–2 mm, margin longer pale green ciliate; blade reflexed, green, with yellow margins, linear, flat or crinkled in upper sheaths.

竿箨黄绿色或者苍白的红棕色，变得稻草色，带有易变依大小排列的棕色的点，基础随着白色的青春期推进；叶耳和口头的刚毛无；叶舌黄绿色，削去或者身体虚弱凸在先端，非常短，1-2毫米，边更长的苍绿色纤毛虫；反折，绿色的叶片，具黄边缘，在上面鞘内皱曲的线形，平或。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
