The heaviest solid (iridium, density r s = 22.6g/cm3, size f 4mm) and liquid (mercury, density r s = 13.6g/cm3, size f 5×2mm ) on the earth is acoustically levitated by greatly enhancing both the levitation force and stability through optimizing the geometric parameters of the self-developed single-axis acoustic levitator.

以上述理论为指导，对自行研制的单轴式声悬浮装置进行了优化设计，显著提高了悬浮力和悬浮稳定性，悬浮起自然界中密度最大的固体铱（ Ir ，密度 r s =22.6g/cm3，尺寸 f 4mm ）和液体汞（ Hg ，密度 r s =13.6g/cm3、尺寸 f 5×2mm ）。

As results showed, for limonin and naringin, the linearity was good within the ranges of 1.00-50.00 mg/L (r=0.9992) and 20.00-160.00 mg/L (r= 0.9988) respectively, and the detection limits were 0.07 μg and 0.14 μg, then the average recoveries were 98.69% and 100.13% with relative standard deviations of 2.5% and 1.5%, respectively.

实验结果表明，柠檬苦素在1.00～50.00 mg/L时线性关系良好(r=0.9992)，检出限为0.07 μg，平均加标回收率为98.69%，相对标准偏差为2.5%；柚皮苷在20.00～160.00 mg/L时线性关系良好(r=0.9988)，检出限为0.14 μg，平均加标回收率为100.13%，RSD为1.5%。

As a developing country, there still have 30 years to stop the production and distribution of R 22 in China , and there are very few technical obstacles in substituting C22 for R 410A . But the substitution will follow with the higher costs of production. And because of the threat of 揼 lobal warming? the future of R 410A is still unclear. How can the air-conditioner industry deal with this problem?

作为发展中国家，中国距最终禁止 R22 的生产与销售还有 30 余年，虽然目前进行绿色制冷剂的替代在技术上的障碍并不多，但随之而来的却是空调生产成本的提高，而且面对着全球变暖的问题， R 410A 等绿色制冷剂的前景还并不明朗，那么在这个问题上，空调行业将走向何方？

Furthermore, significant correlation was found between the amount of myopic correction and the induced changes in log mesopic contrast sensitivity (r =-0.442, P =.0038 without glare; r =-0.464, P =.0024 with glare).

此外，近视矫正量与中间视力对比敏感度log值的变化之间呈显著相关(r =-0.442， P =。0038 无眩光； r =-0.464， P =。0024 有眩光)。
