Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.

作者给出了Canny算子与中心B样条二进小波严格的比较证明，得出如下结论：a中心B样条函数具有紧支集，Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数，中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求，并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143％。f中心B样条函数的导数可以构成稳定的二进小波，存在快速的多尺度算法；而Canny算子不构成稳定的二进小波，无法给出快速的多尺度算法。

Since Tasks B and D will work in parallel 10 days, the critical path will shift to Tasks C, E,F and finally H.

因为任务 B 和 D 的开展将是平行的 10 天，关键路径转移到任务 C，E，F ，和最后的 H。

E. Since Tasks B and D will work in parallel 10 days, the critical path will shift to Tasks C, E,F and finally H.

e。 因为任务B和D 的开展将是平行的10 天，关键路径转移到任务C，E，F ，和最后的H。

A Some environmentalists are againstthe projecton biological grounds（on..grounds/on the grounds of..根据）.D They're what will keep the bridge fromgoing anywhere.F They will tip up the scales at 166, 500 tons – more than half the bridge's totalmass.Getting these cables up will be something. It is not just their length –totally 5.3 kilometers – but their weight.

F。 分析：思路特点：注意空格后句中的词语使用特点：空格前出现了their length， their weight，根据前句内容判断their指"these cables"，空格前句内容的重点在重量上， F具体提到了有关重量的数据166， 500 tons，因此F是答案。
