查询词典 shear angle

The conventional liquid based RP system used a special designed recoat to scrape resin from one side of the tank to the other to ensure the surface flatness. The scraping procedure will take off extra resin but with a drawback of shear force to the working part. In order to overcome the drawback of the shear force, a supporting structure is necessary to build under the working part.

Based on the data of dynamic shear rheometric tests, a constitutive equation was also proposed, which could characterize the dependence of the melt viscosity of PE and its blends on both shear rate and temperature.

此外，在大量mPE和mPE/LDPE共混合金动态剪切流变试验数据的基础上，拟合并推导出能够同时反映PE和mPE/LDPE共混合金熔体粘度对剪切速率和温度依赖性的本构方程，并且通过分析发现，方程中的α值对PE和mPE/LDPE共混合金的熔体粘度的剪切速率依赖性影响较大，α值越大，其熔体粘度对剪切速率越敏感。

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。

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。
