According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea,a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious.

该文根据地海杂波与流星干扰在多普勒谱上的差别，提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来；再根据流星干扰的分布特点分段计算背景噪声均值，求取流星干扰检测门限；最后用杂波信号来插值流星干扰位置上的数据，消除因去除干扰造成的杂波相位不连续。

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

Based on the complexity of the sources for the sediments in the Okinawa Trough, the sequential extraction procedure was applied to the hydrothermal influenced sediments in the core H9 recovered from the middle Okinawa Trough. Five fractions, including exchangeable, bound to carbonates, bound to iron and manganese oxides, bound to organic matter, and residual were acquired. Based on detailed analysis for major, minor and rare earth element compositions, the distributions of the elements in various speciations of the sediments were determined and the controlling mechanism was discussed. The variations of hydrothermal signatures in the core, partitioned from the terrigenous, volcanic and biogenic materials, have been demonstrated and the accumulation rates of some elements were evaluated.

本文针对冲绳海槽多种物源沉积作用混杂的特征，采用顺序淋滤萃取方法对海槽中部受热液活动影响的H9岩芯沉积物进行了分离，将沉积物中分为可交换态、碳酸盐结合态、铁锰氧化物结合态、有机结合态和残渣态五个部分，并对各个结合态中常量、微量和稀土元素组成进行了分析，确定了不同元素在不同结合态中分配的比例，分析了控制不同元素进入沉积物的主要机制。

Blood samples from vein and artery end of the filter, plasma-based dialysate from entry and exit of the filter and ultrafiltrate were taken at 5 min（T0）, 2 h (T1), 4 h (T2) and 6 h (T3) during HD-PBD and 5 min（t0）, 6 h (t1), 12 h (t2) and 24 h (t3) during HVHF. Bilirubin levels of dialysate, ultrafiltrate and plasma were measured and quantity of serum bilirubin removed by extracorpomal circulation was calculated.
