查询词典 representation notation

Space curve is one of the basic elements in geometric modeling, and its effective representation is the basis of modeling. Parametric representation based on features is a kind of high-level representation including semantic information. In Chapter 4, para- metric representations based on features for free form space curve are investigated, and a parametric model for the loop of plain knitted fabric is established, in which 5 parameters with practical meanings are used to represent the shape of a loop and the relationship between loops. A new shrinkage prediction method for knitted fabric are proposed based on the parametric representation and energy minimizing. Experimental results on some plain knitted fabrics illustrate the feasibility of the proposed method.

空间曲线是造型中最基本的几何元素之一，对其有效的表示是造型的基础，而特征参数化表示是其中一种包含语义信息的高层次表示，本文对空间自由曲线的特征参数化表示进行研究，建立了一种针织物线圈的特征参数化几何模型，采用5个具有实际意义的参数表示织物线圈的几何形状及线圈之间的位置关系，并将该模型与能量极小化的方法相结合，得到了一种能较好地预测针织物缩水率的新模型，对随机选取的一些针织布缩水预测实验表明了算法的可行性。

Supported by the National Science Foundation of China, this thesis concentrates on the image sparse representation theories, methods and the image processing applications based on sparse representation. We make deeply study for the applications based on multiscale geometry analysis, theories of overcomplete sparse image representation and its applications, theories of sparse image representation via combined transforms and its applications.

本文在国家自然科学基金项目&联合基图像稀疏表示理论研究及其应用&的资助下，针对图像稀疏表示理论、方法以及基于稀疏表示的图像处理应用问题，重点围绕多尺度几何分析在图像处理中的应用、基于冗余字典的超完备图像稀疏表示理论及应用、组合变换图像稀疏表示理论及应用等内容进行了探索性的研究。

We can use either common decimal notation or scientific notation to write floating-point literal constants.

通常可以用十进制或者科学计数法来表示浮点字面值常量。

Whether the number is printed using decimal or scientific notation depends on the value of the floating-point number being printed. The library chooses a format that enhances readability of the number. Very large and very small values are printed using scientific notation. Other values use fixed decimal.

使用小数形式还是科学记数法显示数值取决于被显示的浮点数的值，标准库选择增强数值可读性的格式，非常大和非常小的值使用科学记数法显示，其他值使用小数形式。

Also note that the notation for the definite integral is very similar to the notation for an indefinite integral.

应该注意到定积分的符号和不定积分的十分相似，其中的原因到最后会显而易见。

This program uses the transformation from infix notation to postfix notation to evaluate most mathematic expressions.

这个项目演示了将中序表达式转换为后序表达式，以计算大多数数学表达式的值。

Function Evaluator - This program uses the transformation from infix notation to postfix notation to evaluate most mathematic expressions.

这个项目演示了将中序表达式转换为后序表达式，以计算大多数数学表达式的值。

Because it is easier to implement, the calculator will use reverse Polish notation instead of infix. Reverse Polish notation is used by some pocket calculators, and in languages like Forth and Postscript.

为了更容易实现，我们在计算器中使用逆波兰表示法代替普通的中缀表示法(逆波兰表示法用在某些袖珍计算器中，Forth与Postscript等语言也使用了逆波兰表不法)。

Her surviving scores reveal Caccini to have taken extraordinary care over the notation of her music, focusing special attention on the rhythmic placement of syllables and words, especially within ornaments, on phrasing as indicated by slurs, and on the precise notation of often very long, melodically fluid vocal melismas.

她幸存的分数显示卡奇尼已接管了她的音乐符号特殊照顾，重点是有节奏的音节词和安置特别注意，特别是在饰品上，措词如诬蔑指出，而在往往很长的精确符号，旋律流体声

Like musical notation , modern mathematical notation has a strict syntax and encodes information that would be difficult to write in any other way.

像乐谱，现代数学符号有严格的语法和编码信息，将是困难的收件以任何其他方式。

As always, there were exceptions to this; i.e.: a feminate male or masculine female, and ultimately it was the Wise Ones who would direct these people to the best areas that they would excel in.

但总有例外；例如：一个女性化的男性或男性化的的女性，最终，智者会指导这些人去他们最胜任的地方。

You are not supposed to sleep at night.

你不应该在晚上睡觉。
