查询词典 hardening

In the extensional rheometric tests, the occurrence of phenomena of "strain hardening1relied on the structure of linear long chains, and mPE didn"t show the behavior of "strain hardening", which implied that the melt strength of mPE was poor.

通过研究发现，在n1PE中混入少量LDPE，不仅能够显著降低n1PE的熔体粘度，提高其熔体粘度对剪切速率的依赖性，而且还可以有效地提高mPE的熔体强度，使mPE熔体在拉伸流动中出现显著的&应变硬化&现象。

Results: In 2007, we provided 602 SPET/CT services in myocardial perfusion scan for attenuation correction and 202 SPET/CT services in other scans for image fusion. Among 64 regional bone SPET/CT services, we noted 2 (3.13%) significant motion artifacts and 2 (3.13%) streak artifacts induced by beam hardening effect while among 25 Ga-67 local SPET/CT services. According to the features including low tube currents and slow rotating speed of this SPET/CT, some problems such as the patient safety, longer scan time, alignment mismatch and radiation protection would be analyzed and discussed.

结果：2007年804例SPET/CT造影中，602例心肌血流灌注断层摄影进行衰减校正，共202例病例进行影像融合，其中鎝－99m-MDP局部SPET/CT发生「影像上明显可见的移动假影」的比例为3.13%(2/64)，镓－67局部SPET/CT发生移动假影的比钊则为24%(6/25)，因射束硬化效应所造成的条状假影有产生干扰融合影像判读的情形，其他问题包括SPET/CT之CT低管球电压及低转速之机器特性、受检者的安全、较长的造影时间、对位错误及辐射防护筝。

他们的论点是基于在硬化中的塑性功是可控制的因子。

The difference between strict terminism and other doctrines is that the time limit is set by God, not by the individual's hardening his own heart.

之间的差异严格terminism和其他学说的是，时间限制是上帝，而不是由个人的强化自己的心。

Until the 20th cent. there were three great developments in architectural construction—the post-and-lintel, or trabeated, system; the arch system, either the cohesive type, employing plastic materials hardening into a homogeneous mass, or the thrust type, in which the loads are received and counterbalanced at definite points; and the modern steel-skeleton system.
