Young people in America often get their driver's license around age 16 by passing a written test and a driving test. 美国的年轻人通常在16岁左右就会通过笔试和路考,取得驾照。
There was little change in the bending strength, Young's modulus and dynamic ductility of the test wood treated by microwave irradiation and steaming appropriately. 适当的微波处理和汽蒸处理使试材的抗弯强度、抗弯弹性模量和冲击韧性并不明显降低。
Rapid adjustment of OPTICAL-LEVEL system in young's modulus test 用光杠杆法测量杨氏模量实验的快速调节
In order to estimate Young's modulus of lightweight concrete more accurately than existing empirical formula, three regression equations are obtained in light of material properties test. 并根据材料特性试验,回归出了三个比现有经验公式与实测值符合得更好的用来估算轻骨料混凝土弹性模量的经验公式。
The parameter of Young's modulus can be defined by three special stress path test and a simple ways to define the parameter of Young's modulus is also proposed, So it more easier than other small-strain model in using. 模型的杨氏弹性模量方程参数可以由3个特殊应力路径方向的试验确定,也可以全部采用常规三轴试验来确定参数,所以参数的确定比一般的小应变模型要容易。
Objective To evaluate the bronchodilation test in tidal breathing of young children with airway hyper-responsive disease, and to establish the diagnostic standard of tidal breathing in young children's bronchodilation test. 目的利用潮气呼吸法进行小年龄儿童的支气管舒张试验,以确立适合0~6岁儿童支气管舒张试验的评定标准。
The mechanic properties of Al-Si closed-cell aluminum foam is affected obviously by its relative density. Its compressive strength and Young's modulus both increase with increasing relative density. All these from test conform well with the results calculated theoretically. 相对密度对Al-Si闭孔泡沫铝材料的力学性能影响显著,随着相对密度的增加,压缩强度和弹性模量逐渐增大,且理论结果与试验结果比较吻合。
The research was to identify the differences of personality traits, the secondary personality factor and practical personality factor between young criminals and young students by Cattell's Sixteen Personality Factor Test. 采用卡特尔十六种人格因素测验问卷,分析比较了青年罪犯与青年学生的人格特质、次元人格因素、应用人格因素。
