For example, when intermediate calculations become larger than can be represented by a floating-point or an integer variable the intermediate result will be invalid.

例如，当中间的计算变得大过可以被floationg-point或整数变量所能代表时，中间结果将是无效的。

从样本整体来看，上市公司中计算出的平均值和中间值显著低于私营企业的平均值和中间值。

Through the thermodynamic calculation of the reaction that aluminum and magnesium reduce anhydrous scandium chloride molten salt to prepare aluminium-magnesium-scandium master alloy, we got that the standard equilibrium constant of the reaction is 1.074 ×10~(19), and the experimental equilibrium constant of it is approximately 6.874 × 10~(14)under around 1200 K and 1 standard pressure, which demonstrate that the reaction can take place and proceed thoroughly.

通过铝镁热还原无水氯化钪熔盐制备铝镁钪中间合金反应的热力学计算，得出：在1200K左右温度，1标准大气压下，该反应的标准平衡常数K为1.074×10~(19)，经验平衡常数K′约为6.874×10~(14)，这说明铝镁热还原无水氯化钪熔盐法制备铝镁钪中间合金的反应能够进行，而且进行的很彻底。

The median velocity was calculated instead of the mean because it is fairly common to find outliers (e.g., breaking a ski pole during the race would make the velocity very low and aberrant).

这里计算的是速度中间值而不是平均值，这是因为中间值较容易发现异常值（例如，在比赛中打破一个滑雪杆会使速度变得异常低）。

In addition, some defects of every method are also discussed ;(2) On the basis of traditional active soil pressure method and expirical siol pressure method , the calculating model of the laternal earth pressure which is a tetragon with the largest value in the center side is addressed.

主要工作如下：（1）本文给出了复合土钉墙的稳定性分析方法，该方法介绍了复合土钉墙的四种破坏类型，分析了每种破坏类型的受力机理，并给出了相应的计算方法和计算方法中的一些不足；（2）在传统的主动土压力和经验土压力的基础上，建立了土钉墙中间大、上下小的四边形状分布的侧向土压力的计算模式。

The calculated results indicate that the flow pattern and the temperature distribution in slab tundish are different at two conditions.

利用该软件计算了板坯中间包钢水在常密度条件和密度变化时的流动状态，以及两种条件下中间包的出口温度。

Calculates the coordinates of the spindle and drive shaft and checking the center distance, determined department spindle must use dislodges the gear.

根据柴油机齿轮室盖的结构特点、加工部位、尺寸精度、表面粗糙度及生产率等要求，确定该机床为单工位卧式组合机床；为确保加工精度，采用&一面两销&的定位方案；为实现无级调速，安全可靠，选择液压滑台；根据零件的大小及被加工孔的位置确定主轴箱的轮廓尺寸；由加工工艺选择滚珠轴承主轴，通过计算扭矩确定主轴和传动轴的直径；齿轮的模数是通过类比法确定；齿轮齿数和中间传动轴的位置是由&计算、作图和多次试凑&相结合的办法确定；计算主轴、传动轴的坐标并进行中心距验算，确定部分轴上需采用变位齿轮；轴上的齿轮套、键等零件按轴号选取相应的标准件。

The research results are as follow: 1. Through the air convection experiment in laboratory, we find that the real measurement of natural convection in laboratory under obturated circumstances is almost sameness to theory calculation. The most notable part of air convection is in the middle part of crushed stones. The bigger the size of the crushed stones is, the bigger the measured wind value is.

主要结论如下： 1、通过室内模拟自然对流试验，得出在室内封闭条件下测得的自然对流效应跟理论计算值相差不大，自然对流效应最明显的部分位于块石层的中间部位；实测的对流涡包都是由一开始的无序状态往块石层的中间部位发展；随着块石粒径的增大，测得的最大风速值也随之增大。

The numerical calculation of grounding grid in large-scale substation under different conditions are carried out, including the breaking of grounding grid occurred in its edge part, in its mid-position as well as in different places simultaneously, thus the variation law of connective resistance of grounding grid under different conditions is obtained.

通过模拟计算，研究了变电站接地网导通电阻的变化规律，对不同情况下的接地网进行了模拟计算，包括边缘部分断开、中间部位断开以及多处部位断开，得出了不同情况下导通电阻的变化规律，结合变电站导通电阻的测试，将测试数据与计算数据进行比较，可判断接地网存在问题的位置。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
