介绍中国京剧英语短文Peking Opera, also known as Chinese opera, is a traditional form of Chinese theatre that originated in the late 18th century. It is widely recognized as one of the cultural treasures of China and has had a significant influence on Chinese culture and art.Peking Opera combines music, vocal performance, dance, and acrobatics into one performance. Its music is characterized by its unique orchestration, which includes the erhu, pipa, cello, drum kit, and gong. The vocal performance style is highly stylized and requires singers to use a range of techniques to convey different emotions and moods.One of the most distinctive features of Peking Opera is its elaborate costumes and makeup. Each character has a specific costume and makeup design that reflects their personality and social status. The costumes are often brightly colored and feature intricate designs, while the makeup is designed to enhance the character's appearance and convey their emotional state.In addition to its visual and auditory elements, Peking Opera also incorporates dance and acrobatics into its performances. These elementsare used to convey the action of the story and to showcase the skill and agility of the performers.Today, Peking Opera continues to be an important part of Chinese culture and is still performed regularly in China and around the world. Its unique blend of artistic styles and cultural influences makes it a fascinating and valuable aspect of Chinese heritage and history.。

PEEK材料简介聚醚醚酮，英文名称polyetheretherketone（简称PEEK），它是分子主链中含有链节的线性芳香族高分子化合物。

其构成单位为氧-对亚苯基-氧-羰-对亚苯基，是半结晶性、热塑性塑料。

总的来说聚醚醚酮(PEEK)树脂是一种性能优异的特种工程塑料，与其他特种工程塑料相比具有更多显著优势，可以在260度的高温下正常工作、机械性能优异、自润滑性好、耐化学品腐蚀、阻燃、耐剥离性、耐磨性、不耐强硝酸、浓硫酸、抗辐射、超强的机械性能可用于高端的机械、核工程、医疗和航空等科技。

PEEK产品特性PEEK（聚醚醚酮）塑胶原料是芳香族结晶型热塑性高分子材料,具有机械强度高、耐高温、耐冲击、阻燃、耐酸碱、耐水解、耐磨、耐疲劳、耐辐照及良好的电性能。

耐高温PEEK树脂具有较高的熔点（358℃），连续使用温度为260℃。

机械特性PEEK(聚醚醚酮)塑胶原料树脂具有良好的韧性和刚性，它具备与合金材料媲美的对交变应力的优良耐疲劳性。

发烟性测量由塑料燃烧所产生烟尘的标准为ASTM E662，此标准是采用美国国家标准局（NBS）的烟尘实验室，以比光学密度为单位，测量由标准形状样品燃烧生产的烟尘的可见光暗淡程度，该测试可以在持续燃烧（有火焰）或燃烧中断（无火焰）的情况下进行，在塑料中PEEK具有最低发烟性。

毒气逸散性PEEK与很多有机材料相同，在高温分解时，PEEK主要产生二氧化碳和一氧化碳，使用英国航行器测试标准BSS 7239可以检测到极低浓度的毒气逸散，这种检测过程需要在1立方米的空间内完全燃烧100克样品，然后分析其中所产生的毒气，毒性指数定义为在正常情况下产生的毒气浓度综合与30分钟可以使人致命的剂量之比，PEEK450G的指数为0.22，且没有检测到酸性气体。

*稳定性PEEK塑胶原料具有优越的尺寸稳定特性，这对某些应用来说有的很重要。

温度、湿度等环境条件的变化对PEEK零件的尺寸影响不大，可以满足对尺寸精度要求比较高工况下的使用要求。

聚醚醚酮树脂（PolyetherEtherKetone，简称PEEK树脂）是由4，4‘-二氟二苯甲酮与对苯二酚在碱金属碳酸盐存在下，以二苯砜作溶剂进行缩合反应制得的一种新型半晶态芳香族热塑性工程塑料。

它属耐高温热塑性塑料，具有较高的玻璃化转变温度（143℃）和熔点（334℃），负载热变型温度高达316℃（30%玻璃纤维或碳纤维增强牌号），可在250℃下长期使用，与其他耐高温塑料如PI、PPS、PTFE、PPO等相比，使用温度上限高出近50℃；PEEK树脂不仅耐热性比其他耐高温塑料优异，而且具有高强度、高模量、高断裂韧性以及优良的尺寸稳定性；PEEK树脂在高温下能保持较高的强度，它在200℃时的弯曲强度达24MPa左右，在250℃下弯曲强度和压缩强度仍有12～13MPa；PEEK树脂的刚性较大，尺寸稳定性较好，线胀系数较小，非常接近于金属铝材料；具有优异的耐化学药品性，在通常的化学药品中，只有浓硫酸能溶解或者破坏它，它的耐腐蚀性与镍钢相近，同时其自身具有阻燃性，在火焰条件下释放烟和有毒气体少，抗辐射能力强；PEEK树脂的韧性好，对交变应力的优良耐疲劳性是所有塑料中最出众的，可与合金材料媲美；PEEK树脂具有突出的摩擦学特性，耐滑动磨损和微动磨损性能优异，尤其是能在250℃下保持高的耐磨性和低的摩擦系数；PEEK 树脂易于挤出和注射成型，加工性能优异，成型效率较高。

此外，PEEK还具有自润滑性好、易加工、绝缘性稳定、耐水解等优异性能，使得其在航空航天、汽车制造、电子电气、医疗和食品加工等领域具有广泛的应用，开发利用前景十分广阔。

在航空航天方面，PEEK树脂可以替代铝和其它金属材料制造各种飞机零部件，利用其优异的阻燃性能，可用来制造飞机内部部件，以降低飞机发生火灾时的危害程度。

在电子电器方面，PEEK树脂具有优良的电气性能，是理想的电绝缘体，在高温、高压和高湿度等恶劣的工作环境条件下，仍能保持良好的电绝缘性。
