查询词典 reflectometry

For the first time, we combined ultrasonic wave and time domain reflectometry to study the relationship between gas hydrate saturation and acoustic parameters in the process of gas hydrate formation and dissociation, and got fine results.

本文首次利用超声和时域反射联合探测技术，研究了沉积物中水合物饱和度与声学特性的关系，并对时间平均方程、伍德及其修正方程、李权重方程和BGTL（Biot-Gassmann Theory by Lee）理论等常用的水合物饱和度估算模型进行了验证。

The water leakages in red soil farmland in northeast of Jiangxi province were studied using large scale weighing lysimeter, time domain reflectometry and tensiometer.

红壤区是我国水土流失严重地区之一，该区降水量大且分布集中，一般认为红壤的入渗透水性能差是引起土壤侵蚀的一个重要原因。

BACKGROUND: Diagnosis otitis media with effusion in children is very important. The commonly used diagnostic methods are pneumatic otoscopy, tympanometry, acoustic reflectometry, and myringotomy.

背景：小儿积液性中耳炎的诊断相当重要，较常用的方法包括：气式耳镜、鼓室图、声反射检查及鼓膜切开术等。

All tests, including acoustic reflectometry, tympanometry, pneumatic otoscopy, and videotelescopy were performed in the two days preceding surgery. Myringotomy or tympanic aspiration was then performed to confirm the presence or absence of OME.

远距镜录影系统检查时病患可采坐姿或站姿，检查者将病患耳郭向后轻拉，再将远距镜经由外耳道放至鼓膜前，在监视器上取得清晰且放大影像。

Peanut or rice wereplanted in the large-scale weighing Lysimeter,pit plots,and standard runoff plots,wherehigh,moderate,and low soil moisture levels were designed as 3 treatments,assemblingwith some instruments such as time domain reflectometry,portable photosynthesis system,dew point microvoltmeter,and porometer.

季节性干旱缺水严重制约着我国红壤区农业的持续发展。1999～2000年在中国科学院红壤生态实验站，利用大型称重式蒸渗仪、测坑小区和径流小区，配合时域反射仪、光合蒸腾仪、水势仪及动态气孔阻力计等仪器，设计高、中、低3种土壤水分处理，进行了花生和早晚稻试验。

Detect and Measure Impedance Mismatches Robert demystifies the topic of time domain reflectometry, which enables you to detect, measure, and locate any impedance mismatch in a transmission line.

Robert使得时域反射仪这一课题不再神秘，它能够帮助您检测，测量以及找出任何阻抗不匹配的输电线路。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
