查询词典 on average

Integrating trellis-coded modulation with threaded algebraic space–time block code, trellis-coded modulation space-time block code is presented, which has the advantage of full-diversity and small detection delay. Based on TCM pre-processing, the minimum distance between different codeword matrixes of the TCMST block code is maximized, so the average bit error rate of the TCMST block code is lower than that of the TAST block code at the same signal noise ratio.

TCMST分组码具有满发送分集度和检测延迟小等优点；由于采用了TCM预处理，使得不同TCMST分组码码字矩阵间的最小距离达到了最大化，因此在相同信噪比情况下，TCMST分组码具有比TAST分组码更低的平均误比特率。

Based on the second- and fourth-order compact difference formulas for second-order derivatives and the idea of weighted average, two classes of the alternating direction implicit method are proposed for solving two-dimensional wave equation. The methods are of accuracy O (T^2+h^4) and O (T^4+h^4) respectively. Stability conditions are obtained by Fourier analysis method.

基于二阶微商的四阶紧致差商逼近公式及加权平均思想，提出了数值求解二维波动方程的2种精度分别为O(т^2+h^4)和O(т^4+h^4)的交替方向隐式格式，以及与其相匹配的第一个时间层的同阶离散格式，并且通过Foulier方法分析了格式的稳定性。

Based on the principle of virtual binary systems, the correlation value is satisfactorily consistent with the ex-perimental data (average deviation for isoamyl alcohol and active amyl alcohol is within 1%).

结果表明，计算值能较好地与实验值相吻合（对于旋性戊醇和异戊醇，其平均偏差均在1%以内）。

We have been growing at an average rate of over 20 percent year-on-year over the decade.

在过去的十几年中我们保持了平均20％以上的年增长速度。

An anatomization on the relative analyzed results is also provided. It is found that the modeling results fit the water monitoring results well with efficiency value greater than 90% and multi-year average relative error value of 3.6%. The case study indicates that the runoff-evaporation hydrological model w...

在阿克苏河流域平原区1980-1995年逐月水量平衡研究中，模拟结果比较符合研究区水盐监测的结果，模型效率系数超过90%，多年平均相对误差仅为3 6%，证明模型在干旱区具备很好的模拟精度，在我国西北内陆干旱区绿洲有进一步应用的前景。

A contact angle of water on the film is in a range of 5 to 30 DEG , and an average surface roughness of the film is 5 nm or less.

水在薄膜表面上的接触角在5-30°范围内，薄膜的平均表面糙度为5nm或以下。

Furthermore, finite element program ABAQUS6.5 was also used to simulate experimental course. Results show that the change of ply splice angle will lead to shear stress concentration on 0 ply in splice region. But the average of shear stress along notch root of specimens almost does not change.

采用有限元软件ABAQUS6.5对实验过程进行模拟，得到拼接层角度改变将引起拼接层中0层出现切应力集中，但沿缺口切应力的平均值几乎不变。

Then the influence of coarse aggregates with average angularity I on hot-mix asphalt properties is studied.

粗集料平均棱角性I对沥青混合料的高温稳定性、低温抗裂性和水稳定性均有不同程度的影响。

该污水厂坐落于弗雷德里克大街的安提坦河畔，设计处理流量为8，000，000加仑/天，2005年年均流量为7，000，000加仑/天。

This year, the first aphid was caught on 25 April, which is almost four weeks ahead of the 42-year average.

今年，第一次被抓获蚜虫4月25日，几乎是四个星期前的42年来的平均水平。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
