It will become less than the theoretic value and the difference between them will augment with the increase of reynolds numbers 表面粗糙度对层流区阻力特性影响明显，层流区摩擦系数低于理论值，且其偏差随雷诺数逐渐增大。
The area ( a ) and the perimeter ( p ) of the tablets at each position are calculated respectively to see whether they agree with the theoretical values 分别计算各位置上药片的面积a和周长值p ，判断是否和理论值基本一致。
The formula of the velocity for ps growth was derived , and was in fairly good agreement with the experimental data in the errors B 、论文得到了多孔硅形成速度的定量表达式，在实验误差的范围里，理论值与实验值吻合得很好。
Theoretically the appropriate mass ratio of hydrated glucose to phosphate was 1 : 2 , but the measurement showed that 1 : 1 was better 在等量的电子供体下，理论上次亚磷酸盐去除率应为磷酸盐去除率的2倍，实测结果与理论值相吻合。
As for { + 7 } li , astronomers have measured only one - third to one - half of what the standard theory suggests should be there 而对于结构为{ + 7 }的锂元素，根据标准理论提出的理论值，天文学家们已经检测到了三分之一至五分之一的量存在。
Some classical chaotic systems are used to check formula , the result indicate the values calculated by the programs accord with the theory values 用某些经典的混沌系统对这些算法进行了验证，结果表明程序计算的实际值和理论值基本一致。
When the signal frequency is 4688hz , the width of the main lobe of the directivity is 28 degrees and the theoretical value is 26 degrees 指向性测试结果显示,最大值方向和第一对最低点宽度与理论值吻合,主瓣宽度实测28度,而理论值为26度。
Based on the above deduction , the numerical solution of the condensation heat transfer coefficient outside horizontal tubes with annular fins is obtained 在此基础上，推导出水平环肋管在数值解法下的管外冷凝表面传热系数理论值的计算公式。
