| 1 | 基于低频滤波法的T-TDR含水率测量方法研究显示文摘为了解决T-TDR(Thermo-time domain reflectometry)探针短,土壤含水率测量效果差等技术问题,提出了一种低频滤波法LFF(Low frequency filter)进行TDR波形分析的计算模型。通过对TDR波形快速傅里叶变换,得到组成TDR波形的频谱,对其低频滤波后重新快速傅里叶反变换,可实现LFF变换。试验通过4种土壤,每种5个含水率的20个土样进行测试,通过LFF法和传统WINTDR法对比,结果表明LFF法具有较好的计算结果,其与干燥法的决定系数R2达0.983 5。LFF法不仅有效提高了T-TDR短针土壤含水率的测试精度,还简化了土壤含水率测试校验程序,提高了测试效率。 | 许景辉 马孝义 Sally D Logsdon | 2014 | 农业机械学报2014，45，6： | 6 |
| 2 | 基于土壤LFUHF频段介电特性的FDR测量频率研究显示文摘土壤介电特性是影响FDR传感器测量土壤含水量精度和适应性的重要物理参数。为了确定28 mm长、10 mm间距的7探针FDR传感器理想频率,通过矢量网络分析仪对4种不同土壤的LF-UHF频段(1 MHz~3 GHz)散射参数进行了测量,通过Logsdon和Laird模型变换,使用Matlab进行了4种土壤表观介电常数的计算和绘制。通过土壤介电频谱分析,研究了土壤极化机理,分析了土壤介电特性与频率的关系,确定了FDR传感器的工作频段为44~398 MHz,考虑到温度对极化的影响,其最佳工作频段为62~110 MHz,其中75 MHz是其工作的最佳频率。此频率下土壤介电值仅对土壤含水量敏感,是消除温度等因素对FDR传感器影响的理想频率。 | 许景辉 马孝义 Sally D Logsdon Robert Horton | 2013 | 农业机械学报2013，44，7： | 3 |

| 4 | Polyp detection rates using magnification with narrow band imaging and white light显示文摘AIM: To compare the yield of adenomas between narrow band imaging and white light when using high definition/magnification. METHODS: This prospective, non-randomized comparative study was performed at the endoscopy unit of veteran affairs medical center in Phoenix, Arizona. Consecutive patients undergoing first average risk colorectal cancer screening colonoscopy were selected. Two experienced gastroenterologists performed all the procedures that were blinded to each other's findings. Demographic details were recorded. Data are presented as mean ± SEM. Proportional data were compared using the χ2 test and means were compared using the Student's t test. Tandem colonoscopy was performed in a sequential and segmental fashion using one of 3 strategies: white light followed by narrow band imaging [Group A: white light(WL) → narrow band imaging(NBI)]; narrow band imaging followed by white light(Group B: NBI → WL) and, white light followed by white light(Group C: WL → WL). Detection rate of missed polyps and adenomas were evaluated in all three groups. RESULTS: Three hundred patients were studied(100 in each Group). Although the total time for the colonoscopy was similar in the 3 groups(23.8 ± 0.7, 22.2 ± 0.5 and 24.1 ± 0.7 min for Groups A, B and C, respectively), it reached statistical significance between Groups B and C(P < 0.05). The cecal intubation time in Groups B and C was longer than for Group A(6.5 ± 0.4 min and 6.5 ± 0.4 min vs 4.9 ± 0.3 min; P < 0.05). The withdrawal time for Groups A and C was longer than Group B(18.9 ± 0.7 min and 17.6 ± 0.6min vs 15.7 ± 0.4 min; P < 0.05). Overall miss rate for polyps and adenomas detected in three groups during the second look was 18% and 17%, respectively(P = NS). Detection rate for polyps and adenomas after first look with white light was similar irrespective of the light used during the second look(WL → WL: 13.7% for polyps, 12.6% for adenomas; WL → NBI: 14.2% for polyps, 11.3% for adenomas). Miss rate of polyps and adenomas however was significantly higher when NBI was used first(29.3% and 30.3%, respectively; P < 0.05). Most missed adenomas were ≤ 5 mm in size. There was only one advanced neoplasia(defined by size only) missed during the first look. CONCLUSION: Our data suggest that the tandem nature of the procedure rather than the optical techniques was associated with the detection of additional polyps' and adenomas. | Nooman Gilani Sally Stipho James D Panetta Sorin Petre Michele A Young Francisco C Ramirez | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 2 |
