Stock stout , forming an erect trunk sometimes up to 1 m tall , apex densely covered with subulate shining brown scales 根状茎粗短，直立，高可达1米，顶端密被棕褐色、具光泽的钻形鳞片。
2.
The study is imitating subulate tool penterite armor fabric by method of test for puncture of paperboard and corrugated fiberboard , and to ascertain the laver of armor fabric for absorb energy and arrestment , and any difference angle to compare the rank of defying ball , for understanding the sharp to the rank of annor fabric defy penterite energy , and penterite deep , the lose energy relation of sharp 摘要本研究是以冲孔强度试验机测试,模拟尖锥利器攻击穿刺防弹衣,且对于防弹衣层数间的阻抗作用及能量吸收的情形,并对各种不同角度的抗弹织物叠层排列作相互比较,进而?解尖锥对防弹衣的抗穿透层数之能量及穿透深度、锥度之能量耗损之间关系。
