手术方法分两类：一类是切除喉的环上区，保留会厌部分，行环-舌骨-会厌固定术；另一类是切除喉环上区，行环-舌骨固定术。

The features of AAA adsorbed on the ethylatedβ-CD polymer were similar with those of the parentalβ-CD polymer, but theadsorption ratios of AAA on the ethylatedβ-CD polymer were higher than those of the parentalβ-CD polymer. It may be due to the strengthened hydrophobic interactions between AAA and the ethylatedβ-CD polymer, which was caused by the ethylation of the parentalβ-CD polymer.

研究表明其对芳香氨基酸的吸附规律与母体β-环糊精聚合物类似；与母体β-环糊精聚合物相比，芳香氨基酸在该聚合物上的吸附率有所增加，这可能是因为乙基化增强了β-环糊精空腔外沿的疏水性，从而增强了乙基化β-环糊精聚合物与芳香氨基酸之间的疏水相互作用。

Data analysis shows that the total amount of PAHs in the sediments of north Taihu Lake is obviously higher than that at the central and south Taihu Lake, and that there is a little difference between the contents of PAHs of high molecular weight and low molecular weight, while the ratio of PAHs varies in different sections of the lake. Through the statistical analysis of the ratio of fluoranthene to pyrene, it is concluded that PAHs mainly come from oil burning with part of them from coal and wood burning.

分析结果表明，太湖北部的多环芳烃总量明显高于中部和南部，低分子量多环芳烃与高分子量多环芳烃的含量差别不大，但在地域上比例有所变化；根据荧蒽/芘的比值统计，多环芳烃主要来源于石油燃烧，部分为煤和木材的燃烧形成。

Totally 60 semi-circular bending specimens cored from superpave gyratory compactor with three groups of notch depths are tested at the temperature of-10 and 20℃ The experimental results reveal good repeatability in EAM characterization. The tensile strength ratio of SCB to the indirect tensile test is at a range of 1.4 to 1.7, and the ultimate strength of EAM is exponentially dependent on the notch depths. At the test temperatures, the critical J-integral value of EAM is much higher than that of hot mix asphalt with thermoplastic asphalt binder. The response mode of EAM changes from ductile mode to brittle mode and the fracture energy increases 30% when temperature decreases from 20 to-10℃, while its critical J-integral value decreases only 15%.

结果表明，环氧沥青混合料的半圆弯曲试验结果复现性好；由非切口试件的半圆弯曲试验与标准间接拉伸试验所测得的环氧沥青混合料的抗拉强度，其比值在1.4~1.7之间，且SCB抗拉强度与切缝深度指数相关；在20℃与－10℃试验条件下，环氧沥青混合料具有比热塑性HMA高得多的临界J-积只分值；当温度由20℃降至－10℃时，环氧沥青混合料的响应模式由延性变为脆性，断裂能增加30%，而临界J-积分值下降15%。

Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.
