芳香树脂

Trees, lofty, emergent, with grayish brown to orange flaky, prominently lenticellate bark and aromatic oily white resin, with stout buttresses.

乔木，极高，自然发生的，具浅灰色棕色到橙的片状的，具显著地皮孔的树皮和芳香的含油性白色树脂，具坚固板根。

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。

Trees or shrubs, evergreen or deciduous, monoecious or dioecious, aromatic, often with resinous, peltate glands.

乔木或者灌木，常绿或者落叶，雌雄同株或者雌雄异株，芳香，通常有盾形树脂腺体。

Any of several aromatic resins, such as balsam of Peru and Tolu balsam, that contain considerable amounts of benzoic acid, cinnamic acid, or both, or their esters.

香脂一种芳香脂类树脂，如秘鲁香脂和塔鲁香脂，含有大量的苯甲酸、肉桂酸，或同时含有这两种酸或其酸酯

The results show that: processing aids which mainly consist of unsaturated aromatic hydrocarbon and aliphatic hydrocarbon resin are able to improve the dispersion of the wood flour in PVC matrix, and amend the interfacial compatibilities between PVC matrix and wood flour, and enhance the mechanical and processing properties of PVC/ wood flour composites; Processing aids which mainly consist of calcium soap and saturated fatty acid amide mixture, as well as fatty alcohol and fatty acid ester mixture, are also able to improve the dispersion of the wood flour in PVC matrix and enhance the processing property of the composites, but when the use amount is big, they have adverse effects on mechanical properties of the composites.

结果表明，以不饱和芳香族碳氢化合物、脂肪烃树脂为主要组分的加工助剂，能够提高木粉在PVC 基体中的分散性，改善木粉与PVC 的相容性，从而明显提高PVC木塑材料的力学性能和加工性能；以钙皂和饱和脂肪酸酰胺混合物、脂肪醇和脂肪酸酯的混合物为主要组分的加工助剂，对木粉的分散性和复合材料的加工性能有一定的改善，但其用量较大时对复合材料的力学性能有不利影响。

With a purpose of making comprehensive use of heavy residual oil, condensed polynuclear aromatic resin is prepared using petroleum asphalt as raw material and terephthalyl alcohol as cross-linking agent under the catalysis of concentrated sulfuric acid or p-toluensulfonic acid.

从综合利用重质油出发，以石油沥青为单体，对苯二甲醇为交联剂，在浓硫酸或对甲苯磺酸催化下合成了缩合多环多核芳香烃树脂。

Firstly, phenyliodine diacetate was immobilized to the 2% cross-linked polystyrene or the liner polystyrene resin. The more iodine the resin had, the lower conversion to phenyliodine diacetate. We made our endeavor to extend the range of useful application of polystyrene supported phenyliodine diacetate in organic synthesis:(1) the reagent was used as an effective reagent of carbonyl regeneration from oximes and semicarbazones of ketones.(2) the reagent was also applied to the synthesis of 1, 3, 4-oxadiazoles, 1, 3-disubstituted-2-pyrazoline, 2-arylbenzoxazole from aldehyde N-acylhydrazones, aldehyde hydoazones and phenolic Schiff's bases respectively.

首先，我们以2％交联的聚苯乙烯和线性的聚苯乙烯树脂为载体，制备了聚合物负载的二醋酸碘苯，通过研究发现：(1)聚苯乙烯二醋酸碘苯是酮肟、缩氨脲有效的去保护试剂，不仅芳香酮，脂肪酮和α，β不饱和酮的肟、缩氨脲也能顺利转化为相应的酮，实现酮基的再生；(2)我们还利用此试剂，分别与醛的N-酰基苯、N-酰基苯腙及邻羟基芳亚胺反应，在温和的条件下发生成环反应，以良好的产率生成1，3，4-噁二唑、吡唑啉和二取代苯并噁唑等杂环化合物；(3)聚苯乙烯二醋酸碘苯还可有效地将邻羟基芳酮的酰腙经氧化、重排成1，2-二酰基苯。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
