Research on Motion Stability Measurement of Guide Rails Based on Position Sensitive Detector

位置敏感探测器(Position Sensitive Detector, PSD)由于具有较快的响应速度、较高的检测精度、非接触性测量等优点，已在振动检测、精密位移测量等方面发挥出越来越大的作用。本文提出了一种基于PSD 的直线导轨二维运动稳定性测量方法，设计了测量系统，进行了重复性和不同速度下的运动稳定性测量实验，并对测量误差进行了详细分析。实验结果表明，该方法可以实现直线导轨二维运动稳定性的高精度、全行程、连续性测量

Ultrasound-guided renal cyst puncture and 95% ethanol instillation. Part 2: Morphological and functional alterations

21症例22腎嚢胞に対して, 超音波ガイドによる経皮的な腎嚢胞穿刺と嚢胞再発防止のための95%エタノール注入をおこなった.1)エタノール注入後3ヵ月～2年4ヵ月(平均12ヵ月)のfollow-upで, 超音波断層検査上, 嚢胞性病変は全例に消失し, CT上, 嚢胞の著明な縮小と嚢胞壁の肥厚を認めた.2) IVPと99mTc-DMSA腎シンチグラム上, 穿刺側で形態的には著明な改善を認め, 機能的にも僅かではあるが, 有意にDMSA腎摂取率の増加を認めた.3)副作用として, 穿刺注入操作にともなって, 1例にカテーテル先端の断裂, 残存を認めたが, 他には重篤なものはなかった.注入エタノールによる局所刺戟症状を全例に, 約半数に熱感～酒酔い感を訴えたが, いずれも一過性であった.1例にエタノール注入後Cephem系抗生物質の使用によりアンタビュース様作用が出現したUltrasound-guided renal cyst puncture was performed on 22 cysts which were then 95% ethanol instilled to prevent recurrence of cystic fluid. Cystic lesions disappeared on the ultrasonogram in the follow-up period of 3 to 28 months. On CT, cystic lesions became smaller size but did not disappear. Average CT numbers of the cyst were 8.75 +/- 3.83 before and 12.96 +/- 3.27 after ethanol instillation. The cystic wall became thicker. Caliceal distortion and/or pelvis compression by cystic lesions improved on IVP 2 to 3 days after ethanol instillation. The renal image on Tc-99m-DMSA scintigram showed morphological improvement and DMSA renal uptake rate increased slightly but significantly 2 to 4 weeks after ethanol instillation. There were no major complications with this procedure except for one case in which the tip of the catheter became stuck in the cyst and broke off when the catheter was removed. A slight local irritable pain was noticed in all cases. Half of the patients had hot flushes and/or somewhat drunken sense but these symptoms were only temporary. Antabuse phenomenon appeared in one case with concomitant use of a cephem antibiotics after ethanol instillation. This method of therapy is a safe non-surgical approach to treat renal cysts. 95% ethanol instillation in the cyst seems to prevent recurrence of cystic fluid

流动沙漠腹地梭梭白粉病防治效果及影响因素分析/Control Efficiency to Powdery Mildew on Haloxylon in the Hinterland of Drift Desert[J]

通过野外试验,分析了3种常见农药对塔中肉苁蓉基地梭梭白粉病的防治效果和影响因素.结果表明:农抗120防治梭梭白粉病比较有效,三唑酮较差.其中三唑酮的防治效果随浓度增大而增强,而农抗120和甲基托布津的防效与浓度无线性关系.浓度为1.66 mL·L-1的农抗120和甲基托布津对塔中梭梭白粉病的防治效果最好.同时,梭梭茎和叶、土壤含水量大时白粉病病情较重,二者密切相关(R>0.96),生产上应在梭梭发病期控制灌水,适当减少土壤含水量
