To analyze the multiple failures , a kind of hierarchical multiple failures expression model based on the mechanism of function failure was constructed according to the mapping relationship between failure mode and function element 摘要為了分析多重故障,根據故障模式和失效功能元素之間的映射關系,構造了一種基于功能失效機理的層次式多重故障表示模型。
Comparing the function system of hangzhou with the international destination cities , there are still some problems : insufficiency in the promoting elements , the lack of intension development of tourism function elements , conflicts between tourism function and living function etc . . some suggestions are also advanced to help the settlement of these issues : to set up function - oriented mbo system , to balance the development of elements for tourists and citizens , to endow the critical elements with priority of development and maximize the benefit of limited resources 根據國際旅游城市功能體系的構成及要素作用特點的研究結果,考察杭州的城市發展和旅游發展,得出杭州已經形成了國際旅游城市功能體系所需要的功能要素,但在功能要素的進一步發展過程中,仍存在要素發展不足或失衡的問題,主要包括:激勵性功能要素發展不足、旅游功能要素的內涵提升不夠、旅游功能與居民功能產生一定的矛盾等。
To solve the overflow or underflow of the components of appearance attributes caused by watermarking , we clip the error ones to the correct ranges by adjusting the corresponding basis function elements . the normalization operation would destroy the watermark embedded in the normal vector . the author presents a novel approach by rotating the normal vector around a fixed axis , which will modify its orientation , not magnitude 其中,針對在外觀屬性分量上植入水印的值溢出問題,作者提出了動態修改基函數的方法;考慮到直接修改法向量分量的方法會受到法向量單位化操作影響導致水印提取困難,作者提出一種繞固定軸旋轉法向量的方法,有效地避免了單位化對已植入水印信息的影響。
