By examining the relationship of the entropy of the degree distribution, scaling exponent and the minimal connectivity, we get the optimal design of scale-free network to random failures.

通过检验网络的度分布的熵、幂指数和顶点的最小度之间的关系，获得了无尺度网络对于随机错误的最优设计。

The stress concentration is a key factor causing fatigue failures. It is very important to make a quantitative research on the stress level and distribution characteristics of BHA.

应力集中是钻具疲劳破坏的一个关键因素，定量计算钻具在井下所承受的应力水平及其分布规律显得尤为重要。

Grandiose claims to be providing the key to feeding the world have been challenged by development agencies from the start, as hunger is mostly caused by failures of distribution, not the total level of world food production.

It also said the failures were often down to the national and local governments responsible for overseeing the distribution of funds, rather than just the European Commission.
