Zhan Ni ·, Ji Weidong (in studying a report, the analyst says the Magenshidanli such as Richard Ji), the reason that tone future does not have concern stock grade on is foreground improves somewhat: 1 China economy is shown anabiosis inchoately evidence, index of PMI obtain employment rose in April to 50.3, break through first since October 2008 50, demand of allusive company service rises; 2 company manages a layer to notice, market of invite applications for a job is already stable since April, predicting employer will be in second half of the year raised pay 2009; 3 future does not have care operation profit margin grows 4% first quarter than going up first quarter, to 7%, because took cost,basically control measure.

詹妮·吴、季卫东等摩根士丹利分析师在研究报告中称，上调前程无忧股票评级的原因是前景有所改善：1中国经济显示出早期的复苏迹象，4月PMI就业指数升至50.3，自2008年10月以来首次突破50，暗示公司雇佣需求上升；2公司管理层注意到，4月份以来招聘市场已经稳定，预计雇主将在2009年下半年增加支出；3前程无忧第一季度运营利润率比上一季度增长4%，至7%，主要由于采取了成本控制措施。

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？

Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.

分别从理论和实验上对长周期光栅的折射率特性以及光纤包层半径对长周期光栅特性的影响进行了研究，首次给出了描述光纤包层半径腐蚀和外界折射率改变与长周期光栅共振波长关系的理论表达式，实验与理论和数据模拟的结果很好符合，利用腐蚀光纤包层的方法可以有效地提高LPG的折射率灵敏度；对不同光纤中写入的长周期光栅的弯曲特性进行了实验研究，LPG的透射峰形状及其中心波长随光纤弯曲而发生变化，并且随着弯曲将在短波方向出现新的透射峰，其透射峰的变化规律因所用光敏光纤的不同而不同，这一特性在光纤传感和可调谐滤波器方面有重要的应用前景。
