查询词典 expected value

First of all, Cauchy inequality is used to obtain a basic inequality. Secondly, the functions of basis are made by Galerkin method, and the error estimates of eignevalues are obtained by Cauchy inequality. At last, the computational method of the approximate value of the eigenvalues turns out immediately, and accuracy of the-th approximate value is estimated by the n-tb approximate value.

首先利用Cauchy场不等式证明了一个基本不等式；其次采用Galerkin方法来构造适当的基函数，并利用Cauchy不等式给出了其特征值计算的误差佑计式；最后得到计算梁横向振动问题的特征值的近似值的算法，而且可以用第n次近似值来估计第n-1次的近似值的精确度。

Cerium oxide could effectively enhance b value of the alumina core materials, but its ability of reducing L value and enhancing a value was a little.

氧化铈可以有效的赋予渗透玻璃黄色品，但对降低玻璃渗透铝瓷明度和增加a值的作用较弱。

The research pointed out the public hospital value chain the characteristic of "the condition debugging value chain", does not belong to the usual value chain type.

研究指出公立医院价值链的"状态调试型价值链"特征，不属于通常的价值链类型。

With the value-oriented customer and taking the BP Neural Network as the instrument,the paper pursues a feasible way to measure activity-based value output of the industry value chain,through establishing the index systems of the supplier,the manufacturer and the distributor,respectively.

以顾客价值为导向，选择BP神经网络法为计量方法，通过分别构建供应商、生产商、销售商的价值链产出价值计量指标体系，研究行业价值链各环节产出价值的计量问题，弥补了价值链理论在行业价值链产出价值计量方面的不足。

All non_array data argument in C are passed "by value"(a copy of the argument is made and passed to the called function; the function can't change the value of the actual variable used as an argument, just the value of the copy it has).

在 C 语言中，所有非数组形式的数据实参均以传值形式（对实参作一份拷贝并传递给调用的函数，函数不能修改作为实参的实际变量的值，而只能修改传递给它的那份拷贝）调用。

First of all, the thesis analyzes and summarizes the theory of customer value, the characteristic of the customer value, and the customer value chain.

而今，产业界和理论界都已认识到了顾客价值的重要性，并且取得了大量的研究成果。

PartⅣ: From the aspect of value chain, the author has analyzed and researched the tourism industrial cluster, set up the value chain model of tourism industrial cluster, and proposed the way to realize the value of tourism industry.

第四部分，从价值链的角度，对旅游产业集群进行分析研究，构建了旅游产业集群价值链模型，提出实现旅游产业价值的途径。

As its coagulum, knowledge of technology is a productive element of commodity, playing a vital role in creation of value; meanwhile, knowledge of technology itself is also a commodity, having its own special user value and value.

作为其凝结物的知识技术既是商品的非实体性、生产要素，在价值创造中发挥着极其重要的作用；同时它本身又是商品，具有特殊的使用价值和价值。

Statistic analysis result shows that the time step is the most important influence factor of simulation precision, and there is relation between simulation error and the setup value of restitution coefficient which the greater the setup value is, the less the simulation error is. Although there is no effect to the total contact time in the course of collision, the value of the time step decides the total contact step, and there is a logarithmic linear correlativity between them.

统计分析结果表明：计算时步是影响模拟精度最重要的因素；模拟误差还同恢复系数的设定值有关，设定值越大，模拟误差就越小；计算时步的大小虽然对碰撞过程的总接触时间影响不大，但是却决定了碰撞过程的总接触时步数，二者之间存在对数线性相关关系
