Tropical cyclones have killed nearly two million people in the last 200 years, so this remaining 'cone of uncertainty' in our predictions is unacceptable.

热带气旋过去200年来造成将近200万人死亡，因此我们预测的不准确度虽然逐步缩小，仍然是不能接受的。

The measurement error source of center of cone gravity, arithmetic and uncertainty of ATS are given, and the measurement accuracy of cone center of gravity is improved.

着重分析了锥体重心测量系统测量误差的来源、算法及系统整体测量不确定度的评定，从而可以提高锥体重心的测量准确度。

First, we relax the uncertainty set to be intersection of a closed convex cone and the translation of an affine subspace.

首先我们放松了对不确定集的限制，把鲁棒线性最优化拓展到凸锥和子空间平移的交的不确定集的情形。
