Testing methods for paints - part 7 : long - period performance of film - section 7 : accelrated weathering exposure to filtered xenon - arc radiation erratum 1 涂料试验方法.第7部分:薄膜的长效性.第7节:加速风化试验
At the point of view of the interaction between university and enterprise , we study hardly theoretical and realistic matters on the long - term cooperation between university and enterprise 摘要本文站在高校与企业互动的视角，研究产学研结合长效性的理论与现实问题。
Together with refrigeration expert taikang from france andcoolingfrom germany ， we designed and developed refrigeration plan to keep longer refrigeration effect according to environment protection 制冷专家法国泰康/德国谷轮与我们一道设计开发制冷解决方案；保障制冷的长效性并确保符合环保要求。
By theoretical analysis from features to functions , we consider the nature of university - industry cooperation is compounding with a series of contracts , which is internally steady and long - term 本文通过“特征功效”的理论分析，认为产学研结合的本质是一系列要素合约的组合，存在着内在的稳定性和长效性。
He speculates that long - lasting immunity might turn cancer from a terminal disease into a chronic one that stabilizes and allows patients to live out their lives , even though traces of malignancy might remain 他预期长效性的免疫力将把癌症从绝症转变成稳定的慢性病，就算病人体内还有一些恶性肿瘤存在，也得以安享天年。
Ha possesses well biocompatibility , which has been discovered through test and in clinical application . however , the relatively large dissolution or resorption rates of ha will result in the failure of the implants . fluoridated hydroxyapatite ( hfa ) in whose structure f " occupies partially the position of oh " in ha , is expected to be more resistant to body fluid and less soluble than ha and still possess almost the same bioactivity as ha 生物活性羟基磷灰石薄膜( ca _ ( 10 ) ( po _ 4 ) _ 6 ( oh ) _ 2 ， ha )广泛地应用于钛合金硬组织种植体表面改性，临床应用发现ha薄膜具有很好的生物相容性，但是ha薄膜在体内溶解速度有时可能会过快，引起种植体在体内失效，因此， ha薄膜长效性方面有待于提高。
Meanwhile , adjusting and optimizing the structure of investment distribution on education should be given attention . the innovation of this article are rest with : 1 ) applying granger causal relations methods to test causal relationships between education investment and economy growth ; 2 ) using time series data to built econometrical model , emphasizing education investment ' s long term feature ; 3 ) projecting future developments by arima model 本文主要创新点在于: ( 1 )利用格兰杰因果关系检验确定教育投资与经济增长之间的因果关系; ( 2 )利用时间序列数据进行建模时,着重体现了教育投资的长效性这一重要的特殊性质; ( 3 )利用齐次非平稳过程的arima模型对我国未来教育投资进行了预测。
