1.The test liquid shall be at a higher temperature than the nil-ductility transition temperature of the material being tested.
这句话这样翻译如何：试验液体温度应该高于材料的零塑性变形温度？收藏指正
2.The ductile-brittle transition behaviour of 16MnHR steel was studied by drop-weight test(DWT), dynamic tear(DT), drop-weight tear test(DWTT) and Cv method. The nil ductility transition temperature(NDTT) of specimens with different thickness and notch sharpness and RTNDT were obtained.
采用落锤试验(DWT),动态撕裂(DT),落锤撕裂(DWTT)和C_v等方法研究了这一钢种的脆性转变特性,得到了不同样品厚度和缺口尖度的无延性转变温度(NDTT)及本钢种的RT_(NDT)。收藏指正
3.Some experimental phenomena in J integration testing were analyzed, and it was found that the Nil Ductility Transition Temperature determined by the load drop of J integration has a good correspondence with one determined by NRL-drop weight test and Charpy impact test, the energy of fast fracture conforms to the Charpy impact energy.
分析研究了J积分测试过程中的一些现象，发现J积分中陡降载荷对应的脆性转变温度和落锤及冲击脆性转变温度有很好的一致性。 快速断裂能量与冲击断裂能量有较好的一致性。收藏指正
