My main interest is in traditionally constructed scale models, built using a balsa framework covered in tissue. 我的主要兴趣是用传统公益制作像真模型(用轻木做框架,棉纸蒙皮)。
Or you can use a couple of thin slices of balsa to make a huge wing, one that will carry maybe twenty engines. 又或许你可以用轻质的木薄片作出巨大的机翼,介样没准可以放20个发动机呢。
Core-spun yams have a central core with a second layer or sheath of fibers wrapped around it. aluminum-surfaced balsa core laminate 包芯纱有一个纱芯,表面包覆有由纤维构成的表层或皮层。轻木芯铝饰面成层塑胶板
Kinkajous, like this one pausing between sips of balsa blossom nectar in Panama's Soberania National Park, are indigenous only to the tropical forests of Central and South America. 热带雨林野生动物图片。蜜熊,像这一只停顿在啜饮巴沙木开花的花蜜之间在巴拿马的主权国家公园,是土著的仅仅在中美洲和南美洲热带森林。
The other is the sandwich structure, FRP/ Balsa/ FRP. 另外一种是3层夹层结构FRP,/软木/FRP粘结组合。
By controlling the thickness ratio, it is confirmed that the GFRP/ Balsa/ GFRP can have the same vibration properties as the musical instrument materials. 实验证明:通过控制厚度比,可使GFRP/软木/GFRP具有乐器用材料的振动特性。
In the analysis of balsa, Kirchhoff's thin plate theory is important. 在板的分析中,Kirchhoff的薄板理论占有重要地位。

To this type balsa, if rectangle thin plate element is sill used will has limitation. 对于复合桩基分析,若仍然采用矩形薄板弯曲单元进行分析,就存在一定的局限性。
