Again i reflected : i scarcely knew what school was : bessie sometimes spoke of it as a place where young ladies sat in the stocks , wore backboards , and were expected to be exceedingly genteel and precise : john reed hated his school , and abused his master ; but john reed s tastes were no rule for mine , and if bessie s accounts of school - discipline gathered from the young ladies of a family where she had lived before coming to gateshead were somewhat appalling , her details of certain accomplishments attained by these same young ladies were , i thought , equally attractive 不过他的感受不足为凭。如果贝茜关于校纪的说法她来盖茨黑德之前，从她主人家一些年轻小姐那儿收集来的有些骇人听闻，那么她细说的关于那些小姐所学得的才艺，我想也同样令人神往。她绘声绘色地谈起了她们制作的风景画和花卉画谈起了她们能唱的歌，能弹的曲，能编织的钱包，能翻译的法文书，一直谈得我听着听着就为之心动，跃跃欲试。
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。
I went to play basketball with my friends that noon , and during the game , after making a skillful interception of the ball , i found our two - meter tall center forward a player who often stays near the hoop to catch balls and make shots already waiting under the backboard , and tried mightily to pass him the ball from the other end of the court 这天中午，又和朋友们去打篮球。我在一次很好的抄截之后，发现我方身高两公尺的大中锋已等在篮下，于是我使出全部力气，想从后场直接把球传给他。
Using the simulation calculation procedure imitate calculating vibration of the driver seat in sample car , the center of the compartment , distance 300 mm of the backboard of the compartment . the result of calculation and experimental result are relatively well identical . have shown the exactness of the vehicle vibration models that are set up and validity of the vehicle vibration simulation calculation procedure 用该程序对样车的司机座椅、货厢中心、距货厢后板300mm三处的振动进行了模拟计算，计算结果与实验结果基本稳合，表明了所建立的车辆振动模型的正确性和车辆振动模拟计算程序的有效性。
For simulating the radial static pressure gradient behind the true turbine guide cascade in low speed wind tunnel with annular cascade , the backboards were placed in the downstream field of the guide model cascade of the low - pressure stage of a turbine , and the effects of the types and positions of the backboards on the outlet flow field of the model cascade were experimentally researched 为在环形叶栅低速风洞实验中模拟实际涡轮级静叶后径向压力梯度，在某型涡轮低压级静叶的下游流场设置了挡板，实验研究了挡板形式及设置位置对静叶出口流场的影响。
