难以计算的 meaning in Chinese
incalculable
Examples
- In the theory of quasiconformal mappings , it is often difficult to evaluate the maximal dilatation of the extremal quasiconformal mapping . how to overcome the obstacle is also a hot point
在极值拟共形映射理论中，极值映射的最大伸缩商往往是难以计算的，如何解决这个问题也是拟共形映射理论中所要讨论的一个热点。 - Using the method of conversing double integrals into linear integrals , we obtain two theorems and their corollaries for double integrals of linear - fractional homogeneous functions with two variables , and construct some typical examples that are difficult to be calculated by ordinary methods to illustrate their applications
摘要通过把二重积分转化成曲线积分，得到二元分式线性齐次复合函数积分的两个定理及其若干推论，并构造一些比较典型的用一般方法难以计算的例子说明结论的应用。 - There are two kinds of retrieval model , full text retrieval and content retrieval , and the vector space model ( vcm ) of the latter is a widely - used method with better effect . the best excellence of vcm is the predominance of knowledge presentation , which expresses documents with vectors in vector space and changes the comparability issue to the distance of vectors , and thus reduces the complexity of documents matching . however . we can not affirm the absolute effect of it , and in this thesis we prove its nonproficiency through experiments
向量空间模型最大的优点在于知识表示方法上的巨大优势，用n维空间的向量表示文档，用向量之间的夹角表示文档的相似度，从而将文档信息的匹配问题转化为向量空间中的矢量匹配问题，将难以计算的文字量化成很容易计算的实数，使问题的复杂性大大减小。但是，并不能够说目前的向量空间模型是最理想的，本文通过实验证明了vcm表达信息的不精确性。 - Article 48 if a copyright or copyright - related right is infringed , compensation shall be paid according to the actual loss of the right owner by the person who made the infringement ; if the computation of the actual loss is difficult , compensation may be paid according to the illegal gains of the person who made the infringement
第四十八条侵犯著作权或者与著作权有关的权利的，侵权人应当按照权利人的实际损失给予赔偿；实际损失难以计算的，可以按照侵权人的违法所得给予赔偿。 - Aiming at the 28km long river regulation and protection works on fuyuan reach where the river evolutions are complicated and the dimensions of control works are difficult to calculate , this dissertation is to study three - dimensional numerical analogue not only under natural conditions but also under ten regulation schemes , using the river sediment quasi - two - dimensional model associated with the river sediment plane two - dimensional model and the river three - dimensional model
