1.The experimental results show that the distribution of the radial static pressure behind the model cascade can be controlled by changing the diameter, number and distribution of the holes at different radius of the full circled backboard with the holes properly， and the experiments variable enthalpy drop in the model cascade can be realized by using out-circled backboard or in-circled backboard which are set on the different distances from the trailing edge of the model cascade.
实验结果表明，适当选择全环钻孔挡板不同半径处的钻孔率、钻孔直径与分布，可调节静叶后径向静压分布，采用外环或内环挡板，并将其分别置于静叶的近、中、远下游，可实现静叶栅的变焓降实验。
2.This is a transparent backboard.
这是透明的篮球板。
3.To play(a ball) in such a way as to make it glance off a surface, such as a backboard or wall.
使弹过拍（球）使之弹跳过阻挡物，如挡板或墙等
4.To retrieve and gain possession of the ball as it bounces off the backboard or rim after an unsuccessful shot.
抢得篮板球在球没有入篮而是从篮板或篮框弹出来之后重新获得球的控制权
5.The depth of dent of box backboard contained D-90031 was numerically modeled in STEVEN test, and the strain at the measured point was also modeled. The results indicated, when the velocity of shot was less than 100m/s, the model and parameter of materials could reproduce the depth of dent and reflect the trend of measured point.
对模拟材料D-90031在STEVEN试验中应变及炸药样品盒背板凹坑深度进行了数值模拟,模拟结果表明,在射弹低速撞击的情况下(≤100m/s),所选用材料模型及参数能够再现炸药样品盒背板的凹坑深度,计算结果能够基本反映测试点应变的变化趋势。
6.In this article, we represent a test unit adapt (TUA) plus industrial computer design for the integrated display system of a kind of helicopter. Based on the unit under test, and combined with the backboard of the industrial computer integrated the ARINC 407, ARINC 429 and an RS422 communication bus, the TUA was designed. The system software of the test system was developed under LabWindows/CVI development environment and database.
本文为某型直升机综合显示系统检测仪提出工控机加适配器的解决方案,利用工控机的背板集成了ARINC407、ARINC429、RS422几种通讯总线,根据被测对象合理地设计了适配器,最后在LabWindows/CVI开发环境中,基于数据库完成了测试软件的设计。
7.That air ball went no where near the backboard.
那个篮外空心球投得离篮板太远了。
8.Twice in the post with left-handed miniature hooks, one a swish, the other enjoying the backboard.
有两次在禁区用左手小勾手得分，其中一个空心入网，另一个则是打板入框。
9.You needn’t erase the backboard after class.
课下你不必擦黑板。
10.He collapsed a backboard support in his first NBA appearance on television,delaying the game 45 minutes.
他第一次参加NBA篮球赛出现在电视上时就把篮板支架拉倒了，使比赛中断了45分钟。
