元素的符号

Give the chemical symbol of Y, and the empirical formula of Argyrodite.

计算Y元素的原子量，给出Y的化学符号和硫银锗矿的的化学式。

With respect to phonetics, Distinctive Features for the phonetic syncopation of spatial information are extracted based on Bertin's retinal variables. The importance of geographic reality, cognitive laws and geometric laws in the syncopation is pointed out following the thorough inspection of the physical characteristics of spatial information and a phonetic hierarchy of phoneme、 phoneme combination is proposed after the summarization of different methods of syncopation in Psychology, Pattern Recognition, Mathematic Morphology and Cartography, which provides linguistic interpretation for cartographic symbol design and understanding. With respect to the property that map symbol is represented as the combination of attribute and geometry in digital form of spatial information, suprasegmental phoneme as unit is proposed which deals with the high level phonetic units and their structure with the bend of curve and the simple area of complex area as primitive.

在语音结构方面，基于Bertin的视觉变量，提取了产生空间信息语音切分的区别特征；对空间信息的物理特征进行了详尽分析，指出了地理真实、认知规律和几何规律在语音切分中的重要作用；在总结心理学、模式识别、数学形态学和地图学等相关切分理论的基础上，提出了空间信息音位系统以及音位组合规律，为地图符号设计与理解提供了语言学解释；针对地图符号通常在空间信息中表现为属性和形态相结合的特点，提出在超音段音位层次上重点关注以线切分单元——弯曲和复杂面切分单元——弯曲构成的简单面为基本元素的语音高级层次及其结构。

Each chemical element has been given a name and a distinctive symbol.

每个元素被给予一个名字和独特的符号。

This paper also proved that the formal representation is faithful to RBAC model.

用描述逻辑的符号给出了RBAC中主要的元素和关系的形式化定义，并证明了这种描述逻辑表示对于RBAC模型的忠实性。

In a mathematical or logical expression, a symbol that may be replaced by the name of any element of a set .

占位符号数学或逻辑用语，可以用其它元素的名称代替的符号

Simulation results show that mean error of this algorithm is generally below 0.05 when 200 training symbols are used.

模拟结果表明，在使用约200个训练符号时，相关矩阵中每个元素的平均估计误差在0.05以下，而使用更多的训练符号时，估计精度将会进一步提高。

On the periodic table of the elements, Mp is the new symbol for gold.

元素周期表中，Mp是一种新发现的金子的符号。

By introducing the steepest descent algorithm , conjugate gradient algorithm , Newton algorithm , Rayleigh Quotient Iteration algorithm and variable metric algorithm , the MSBMDA is implemented iteratively.

MSBMDA算法将盲多用户信道估计或多用户信息符号估计的模糊度限制到以±1，±j为元素的对角矩阵内，并消除了用户次序的模糊度。

Although Wagner criticized Semper for stopping at a symbolism of construction, and although these symbolic elements occur much less frequently in Wagner's work after 1905, they never disappear completely, the wreath being the predominant ornament in both the Postparkasse and St.

虽然瓦格纳批判了森佩尔停止在构造的符号化上，并且在1905年以后这些符号元素在瓦格纳作品中的出现频率大大减少，但它们几乎从没完全消失，花圈作为次要的元素，同时出现在邮政储蓄银行和St。

Designer use the pattern、constitute lanaguge and so on.Through the symbol to show personal design ideal .The design of symbol also select、re-constitute evolution and creat the typical symbol fundamental.The nationality's decoration、wear system are breaked、analysized、dispersed and used again in modern fashion design.

设计师运用一定的图像、构成等语言，通过可感知的符号表现自我的设计理念；符号的设计又是对典型符号元素的精选、重构、演化和创造，民族原生的装饰、佩戴、穿着体系被打散、分析、解构，重新运用于现代服饰设计中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
