The analysis of the repeated test data shows the maximum deviation of air drag coefficient is less than 0 . 88 % and the deviation of the most surface pressure data is within 1 % , it illustrates the test data is reliable 重复试验的数据分析表明,空气阻力系数数据的最大偏差小于0 . 88 ,绝大部分测压试验数据的偏差均在1以内,这说明客车模型风洞试验数据的精度较高。
The relative viscosity of pcaneg block copolymers can be stablized in the range from 2 . 0 to 2 . 3 in repeated tests , and the amplifying tests can be repeated accurately the mechanical and amistatic properties and microstates of blend are researched when the ratio of pa6 to pca / peg b1ock copolytner varies 3 ,放大工艺条件重现性好。研究了不同pa6和pca peg嵌段共聚物共混比时混合物的机械性能、抗静电性能和微观形态。
Memory retrieval deficit pattern , step - through test was adapted to train mice at 1 hour after the last administration , the test was given after 24 hour . a blank control group received ig of equivalent normal saline , the remaining 5 groups received ig of 10ml / kg 40 % alcohol at 30min before repeated test 记忆再现障碍小鼠,在末次给药后1小时使用避暗法训练小鼠, 24 j ’时后重新测试,测试前30ndn灌胃40乙醇10im kg 。
The v was tested by yjy stress transducer with mvad card by the methods of recording the deformation in the wideness and thickness direction of the specimens during the tensile test . a stable auxetic polyolefin blend with the minimal value - 1 . 4 was observed after repeated test 采用附有mvad通道卡的yjy型片式传感器,记录试样在拉伸过程中宽度和厚度方向的形变并根据泊松比的定义进行计算,反复实验后获得最小值为- 1 . 4的负泊松比烯烃共混体系。
Over the years , the company independent innovation and invention duty , in particular the use of sophisticated technology of modern microelectronics technology , and strive to explore clean coal gasification and combustion heat the best possible use of the method , so as to achieve environmental protection , energy saving , safety and easy - to - use purpose , commitment to the new environmental generation of intelligent energy - saving boiler equipment series product development and manufacturing , through repeated testing , improvement , the test units and hundreds of users use , continuously improve product performance , technology is improving daily , manufacturing production has been stereotyped by the third generation products " disorientated " card microcomputer control automation system gas boiler energy conservation and environmental protection official on the market 多年来,公司以自主创新和发明创造为己任,利用尖端科技尤其是现代微电子技术,努力探索实现煤炭煤气化洁净燃烧和热能尽可能得到充分利用的方法,从而达到环保、节能、安全和使用方便的目的,致力于新一代智能型环保节能锅炉设备系列产品的研发和制造,经过反复试验、改进,试销和几百个单位用户的使用,产品性能不断提高,技术日臻完善,现已定型制造批量生产的第三代产品“ ?牛”牌微电脑自动化控制煤气节能环保锅炉正式推向市场。
