Tougher than steel and intricately

Tougher than steel and intricately (复杂地) woven, spiders’ webs are certainly a natural wonder.
Now a team of scientists have worked out why they are resilient (有弹性的) enough to withstand the force of hurricanes and fierce attacks form predators (捕食性动物). It is not just the strength of the silk, but the clever design that has astonished scientists.
A typical garden spider’s web takes a huge amount of the insect’s energy to build—so it contains a series of features which stop major repairs being needed.
In tests against three other materials made into similar webs, spider silk was six times more resilient to damage when they subjected it to high winds. When a weight was applied, only one thread broke off—so the spider could just do minor repairs rather than start building it again. Removing up to 10 percent of the threads from various different areas made the web not weaker but actually three to 10 percent stronger.
Co-author Markus Buehler, professor of MIT, said, “It is really interesting that they have built the web with failure in mind. One thread is designed to break when the web faces a threat so that it still functions as a web and remains strong.” Scientists have already shown how spider silk is about five times as strong as the same weight of steel.
The study looked in detail at every aspect of spiders’ webs from the smallest molecules (分子) in the silk to the complicated building techniques the spiders use. Spider silk is made of proteins that are not used in many materials, but the authors believe they could be used in a new generation of household products.

比钢和错综复杂的（复杂地）编织蜘蛛网当然是一个自然奇观。现在，一组科学家已经找出他们为什么弹性（有弹性的）足以抵御飓风和凶猛的攻击力（捕食性动物）形式的食肉动物。它不仅是丝绸的力量，但聪明的设计，使科学家们惊讶。一个典型的花园蜘蛛网需要大量的昆虫的能量来建立，所以它包含了一系列的功能，停止重大维修是必要的。在试验中，对其他三个材料制成类似的网，蜘蛛丝是六倍更有弹性，以破坏时，他们受到强风。当一个重量被应用，只有一个线程打破了，所以蜘蛛可以只做一些小的维修，而不是开始建设它。删除多达百分之10的线程从不同的领域，使网络不弱，但实际上是三至百分之10强。作者Markus Buehler，教授，麻省理工，说，“这是非常有趣的，他们的失败在心网络的构建。一个线程被设计来打破当网络面临着一个威胁，使它仍然作为一个网络的功能，并保持强劲。“科学家已经展示了如何蜘蛛丝的重量是相同重量的五倍。研究了在蜘蛛网从最小的分子的每一个方面（分子）在丝复杂的建筑技术的蜘蛛。蜘蛛丝是由不使用多种材料的蛋白质制成的，但作者认为它们可以被用于新一代的家用产品中。
