查询词典 U-bar

The pressure drop of airflow consisting of pressure drop of the perforated plate and liquid-layer is mainly influenced by the plate dimension and bare tower velocity, with the increasing of bare tower velocity, pressure drop of the perforated plate increases. The experimental data are used to develop a correlation as follows:ΔpD＝1.04×10－82g This correlation should be used whenβ＜5％,0.299m/s＜u＜

空气流动的阻力主要由孔板阻力和液层阻力组成，孔板阻力主要受多孔板的几何尺寸及空塔速度的影响，空塔速度越大，孔板阻力越大，对实验数据进行回归分析得出的实验关联式为：ΔpD＝1.04×10－82g 公式适用范围：β＜5％，0.299m/s＜u＜

The two prex characters may be combined; in this case,'u' must appear before 'r'.

这两个前缀可以组合使用，但'u'必须在'r'之前。

Here we dated the Lianhuagou pluton using LA-JCPMS zircon U-Pb method, for molybdenum polymetallic deposit evaluation and prospecting in Luonan county, Shaanxi province in recent years.

本文是笔者近几年在陕西省洛南县灵口地区开展钼多金属矿找矿评价和研究工作中，利用LA-ICPMS锆石U-Pb法新获得的莲花沟岩体同位素年代学数据的研究成果。

However, to determine the form of the current round of economic recovery has become a matter to make it difficult, the general view is: V-shaped impossible, L-shaped (Japan Heisei recession-type) does not exclude, zigzag (recovery time, sometimes a recession), U-shaped or bottom of the pot-shaped (long-term low-growth to resume growth) higher probability.

然而，确定了本轮经济复苏的形式已成为一个问题，使困难，一般的看法是：V形不可能，L形不排除，锯齿（恢复时间，有时是经济衰退），U形或锅底形的可能性较高。

By the improved algorithm of exploring iterative interpolation method, the pre-estimate formula in the form of 2-order differential equation have been replaced by pre-estimate formula in the form of 1-order differential equation, confirm the u monotony accession strictly. It could avoid the interpolation direction converse and oscillation.

算法采用改进的探索迭代法实现，用一阶差分预估器代替二阶差分预估位置点的偏差器，保证曲线参数u的严格单调增加，以消除插补方向反转和振荡现象。

North building materials is one of the earliest large-scale introduction of international advanced equipment, PVC-U plastic profile production line, one of the company.

北新建材是国内最早大规模引进国际先进设备 PVC-U 塑料型材生产线的公司之一。

The inflow rate along the wellbore is not equivalent, but distributes like"U"shape, and inflow rate of the two ends is higher than that of the middle part. When the inflow reaches its pseudo steady flowing, the distribution shape of flowing keeps steady.

5井筒压降80％出现在距水平井跟端50％的井长内，沿水平井简单位长度的流入量并不相等，沿井筒形成U形流入分布，在水平井的两端的流入比井筒中部的流入相对要高，一旦达到拟稳态流动，沿井筒的流入分布形状基本保持不变。

The main results are as follow: strong patent scope is helpful for information disclosure. However, the effect of patent scope on social welfare and pace of technological progress shows a quasi inverted-U shape. Therefore, the optimal patent scope is finite.

我们发现：强的专利保护宽度有利於资讯披露，但其对社会褔利和技术进步的影响却呈近似的倒U型，故在不同的情况下都存在一个专利保护宽度的最优取值区间。

It is found that the threshold for emergence of quasi fission in the reactoin system is 8 MeV/u.

发现对本反应系统，准裂变的出现至少需要8MeV／u阈能
