Characteristic absorption peak of the human blood measured with differential photoacoustic spectroscopy

A new highly sensitive spectroscopy technique- differential photoacoustic spectroscopy (PAS) is presented in this paper. The blood samples from 3 healthy persons, patients with leukemia, patients with pregnancy-induced hypertension (PIH), and 40 patients with nasopharyngeal carcinoma were measured by the PAS technique. The normalized, the first order, and the second order differential photoacoustic spectroscopy of the blood were gained. The results show that (ⅰ) weak absorption peaks or shoulder peaks, which could not be found using conventional photoacoustic spectroscopy, were determined by the first order and the second order differential photoacoustic spectroscopy which significantly improve the sensitivity of detection; and (ii) that two characteristic absorption peaks were found at the wavelength of 637 and 664 nm in all persons' blood samples by the differential photoacoustic spectroscopy technique. This experiment concludes that the differential photoacoustic spectroscopy technique is superior to the conventional photoacoustic spectroscopy technique in detecting photoacoustic spectroscopy of biological samples.

HermitFS： A Secure Storage System in the Open Environment

We present a secure storage system named Hermit FS against many types of attacks. HermitFS uses strong cryptography algorithms and a secure protocol to secure the data from the time it is written to the time an authorized user accesses it. Our experimental results and secure analysis show that HermitFS can protect information from unauthorized access in any open environment with little penalty of data overhead and acceptable performance.     

贵港市山地利用现状及开发途径分析

贵港市位于北回归线以南，自然地理条件优越，交通便利．山地主要为林地，部分为荒地，经济林比重小，土地利用率和经济效益低．应该充分发挥本地优势，开发利用山地．用经济效益高的果林和经济林代替现有林地和荒地，使山地能持续稳定地发挥最佳经济效益．

ZA—27耐磨合金的悬浮铸造

ZA—27合金铸件很容易产生底缩。根据黑色金属中应用的悬浮铸造的作用原理,我们探讨了悬浮铸造对ZA—27合金中存在的比重偏析和底缩、以及对合金组织及性能的影响.结果表明,悬浮铸造可显著降低铸件各部位的密度差,减轻甚至消除底缩.悬浮铸造使合金的枝晶组织细化,冲击韧性提高40％,耐磨性提高了11—13％。
