Less Is Mere
It sounds all wrong -- drilling holes in a piece of wood to make it more resistant to knocks.But it works because the energy from the blow gets distributed throughout the wood rather thanfocusing on one weak spot. The discovery should lead to more effective and lighter packagingmaterials. Carpenters have known (51) __________ centuries that some woods are tougher than others. Hickory (山核桃木), for example, was turned into axe handles and cartwheel spokes(輪輻) because it can absorb shocks without breaking. White oak, for example, is muchmore easily damaged, (52)__________ it is almost as dense. Julian Vincent at Bathe University and his team were convinced the wood's internal structure could explain the differences.
Many trees have tubular (管狀的) vessels that run (53)__________ the trunk and carry waterto the leaves. In oak they are large, and arranged in narrow bands, but in hickory they aresmaller, and more evenly distributed. The researchers (54)__________ this layout might distribute ablow's energy throughout the wood. soaking up a bigger hit. To test the idea, they drilledholes 0.65 millimetres across into a block of spruce (云杉), a wood with (55)__________ vessels,and found that (56)__________withstood a harder knock. (57)__________when there were more thanabout 30 holes per square centimetre did the wood's performance drop off.
A uniform substance doesn't cope well with knocks because only a small proportion of thematerial is actually(58) __________All the energy from the blow goes towards breaking thematerial in one or two places, but often the pieces left(59)__________ are pristine ( 未經破壞的).But instead of the energy being concentrated in one place, the holes provide many weakspots that all absorb energy as they break, says Vincent. "You are controlling the places(60) __________the wood breaks, and it can then absorb more (61)__________, more safely. " Theresearchers believe the principle could be applied to any material -- (62)__________ example, tomanufacture lighter and more protective packaging. It could (63) be used in Carbumpers, crash barriers and armour for military vehicles, says Ulrike Wegst, a (64)__________ atthe Max Plank Institute for Mental Research in Stuttgart. But she emphasizes that you(65) to design the substance with the direction of force in mind. "The direction ofloading is crucial," she says.
