查询词典 rate

During the non-isothermal crystallization, compared with common PE, the cooling rate had less impact on the crystallization rate of mPE. Second, the sensitivity of the melt viscosity of mPE to the shear rate was poor, and the introduction of long chain branches onto the molecular structure of mPE could improve the dependence of their melt viscosity on both shear rate and temperature. In the extensional rheometric tests, the occurrence of phenomena of'strain hardening' relied on the structure of linear long chains, and mPE didn't show the behavior of'strain hardening', which implied that the melt strength ofmPE was poor.

其中通过共聚方法在mPE分子中引入非线性长支链结构，对提高mPE熔体粘度对温度的依赖性作用较为明显，而对提高mPE熔体粘度对剪切速率的依赖性以及对提高mPE熔体强度作用较弱；采用共混方法在mPE体系中引入线性长支链结构，则对提高mPE熔体粘度对剪切速率的依赖性以及提高mPE的熔体强度的作用较为明显，而对于提高mPE熔体粘度对温度的依赖性作用相对较弱。

In sparkle discharge ,following conclusions could be reached:(1) overall spectral intensity in nitrogen is lower than in oxygen . When water is added, integrality light intensity is lower compared with the pure gas condition.(2) No matter it is nitrogen or oxygen, when water is added, syllabify three spectral lines of atomic H: Hα(656.3nm), Hβ(486.1nm), Hγ(434.0nm) could be seen. What is more, when water is added into oxygen, the spectral line of H atom becomes stronger.(3) When discharge in pure nitrogen, the light intensity falls with the increasing gas flow rate. While if water is added, the light intensity will rises with the increasing gas flow rate.(4) When discharging in pure oxygen, the light intensity rises with increasing gas flow rate. While if water is added, with increasing gas flow rate the light intensity initially will change as this:first rise, then saturate at about 140l/h, finally falls.
