查询词典 assessable contribution

Although we can see that radiative correction term is less than the contribution of the free gauge field to the Casimir force, our result of the radiative correction to the Casimir force of M-C-S gauge field at zero temperature, will possess referenced value for measure of the Casimir force experimentally.

从所获得的量子涨落对M-C-S规范场的Casimir力的辐射修正的结果来看，虽然辐射修正值与自由规范场对Casimir力的贡献相比小的很多，但对于提高测量Casimir力的精度，将会提供可参考的理论依据。

We are cordial hope Party school teachs by correspondence contribution of teachers and students, also welcome not stint of all circles friend to give manuscript.

The main contribution of this thesis is that we propose a collaborative filtering recommendation algorithm based on double clustering. This approach first respectively clusters resources and users by the users rating on items, then makes a collaborative filtering recommendation based on the clustering result. The new algorithm can shorten on-line recommendation time. Then, we apply the classical formula of cosine correlation to double clustering algorithm, leaving out the standardization operation. In the end, we implement an educational resource recommender system according to the need of the actual project and the result is positive.

本文的主要意义在于，首先运用聚类技术对用户和资源分别进行聚类，然后利用聚类结果进行协同过滤推荐，由于聚类部分离线周期进行，大大缩短了在线的推荐时间；然后将经典的余弦相似性计算公式运用到双重聚类算法中，省去规范化处理操作，减少运算量；最后结合实际的需要，实现一个资源推荐系统。

If Q2 were negative, this might be representation of E2, pointing to negative charge, and if this one (Q3) were negative, then I would have here the contribution E3, and so on, and now we use the superposition principle as we did last time which Coulomb's law, that the net electric field at point p is a vector, is E1 influence of charge Q1, plus the vector E2, plus E3 and so on.

如果Q2是负的，这就是Q2的表示法，方向指向负电荷。如果这个是带负电，它将贡献电场E3，等等。现在我们使用叠加原理，就像我们上次在库伦定律中使用到的。
