In this paper two wholly aromatic copolyesters, LCP-111 and LCP-116, provided by Chenguang Institue of Chemical Technology, were blended with two types of high performence engineering plastic, poly and poly with cardo group respectively. Research work was done on the phase morphology, phase separation process, crystallization and melting behaviors and their influence on the properties of LCP/PEEK and LCP/PES-C blends.

本文使用国产的仿Xydar全芳共聚酯LCP分别与二种新型的高性能工程塑料聚醚醚酮和酚酞型聚芳醚砜共混，主要对LCP及其与PEEK，PES-C共混物的相态结构，相分离过程，结晶和熔融行为以及这些因素对性能的影响做了大量的基础研究工作，这些工作是实用改性的理论依据，并且是高聚物共混理论研究中的一个新领域。

The results show that there existed at least two populations of lamellae in PEEK and other semi-crystalline polymers when isothermally crystallized.

结果发现PEEK及其他半结晶性高分子於等温结晶时便已形成两种以上之晶板分布。

PEEK is a kind of thermoplastic resins which has a lot of excellent properties in many fields and can be reinforced by many types of fillers. When it is reinforced by carbon fibers, its strength and wear resistance are improved. Though PEEK/Cf composite has many advantages, its applications are limited just for it is nonconductive.

PEEK是一种结晶性、不透明、浅茶灰色的芳香族系超耐热热塑性树脂，具有坚韧、高刚性和耐蠕变性好等特点，采用碳纤维复合增强，形成了性能更优越的PEEK/Cf复合材料，提高了PEEK的强度和耐磨性，改善加工性。

In particular, the single-character operations that put characters back on the stream are also unformatted input operations. If peek, unget, or putback are called before calling gcount, then the return value will be 0!

尤其是，将字符放回流上的单字符操作也是未格式化输入操作，如果在调用 gcount 之前调用 peek、 unget 或 putback，则返回值将是 0！
