In order to advance the capability of correlation signal detection method, a new method for LFM signal detection,based on the technology for ambiguity resolution of stagger repeated frequency, is proposed. Using the method, the signal in low signal-to-noise ratio can be detected very well and its parameters can be estimated more precisely too.

本文提出基于重频参差解模糊技术的信号参数估计方法，通过相位解模糊，实现了在低信噪比条件下对信号参数更有效地侦取，并对处于白噪声环境下的窄带和超宽带LFM信号进行了仿真，验证其有效性。

Coning and quartering method: put the sample onto the steel plate in the form of a cone; each scoop shall be inserted from the top of conical to make it spread along the top evenly, and pay attention not to misplace the center of cone; do it at least 3 times and mixed thoroughly; then flatten the top and use the cross plate from top to bottom to divide into 4 equal segments, randomly take out 2 oppositesegments and do it repeatedly for several times and finally divided into not less than the minimum retained quantity.

圆锥四分法：将样品置于已用样品刷好的钢板上，堆成圆锥形，每铲由圆锥顶尖落下，使其均匀地沿锥尖散落，注意勿使圆锥中心错位，如此反复至少移堆三次，使其充分混匀，然后将锥尖压平，用十字板自上插下，分成四等份，任取两个对角的等份，重复操作数次，缩分至不少于最少留样量。

Abstract］ Objective To investigate the change of bronchial mucosa cilia epithelium structure on children with recurrent respiratory tract infection in acute stage and convalescence stage.Methods Choose 38 cases of patients with RRTI as study group,respiratory ciliated cells were collected by bronchial fiberscope in acute stage and convalescence stage respectively,observe the change of cilia structure by electron microscopy and compare the incidence of cilia cylindrical epithelium structure abnormality.

摘要］ 目的研究反复呼吸道感染患儿急性期与恢复期支气管黏膜纤毛上皮结构的特点与变化，临床治疗的有效性提供客观依据方法选择符合儿童RRTI诊断标准的患儿38例作为研究对象，分别于急性期及恢复期在纤维支气管镜下夹取支气管黏膜组织，电镜下观察纤毛上皮结构的特点并比较纤毛异常的发病率，探讨RRTI患儿治疗后纤毛的恢复情况。

Secondly was honeysuckle and peach tree wood.So,in poor karst area,in order to link environmental benefits,eco-efficiency and social and economic efficiency,it were best measures to plant prickly ash peel or honeysuckle.It can improve capability of holding nutrient in short phase.,also it were beneficial to soil fertility,and hold back soil erosion.Sampled soil in a camphor slope,through analyzed on soil nutritive elements,like that Ca,Mg,Cu,Zn,Mn,Mo,Si,Fe,we had a deeper understanding with soil ground erosion and underground soil leaks.

通过时间对比分析，得出不同土壤利用方式下土壤养分保持能力和土壤退化的变化趋势，提出运用土壤指纹电荷方法对某一研究区域的土壤养分保持能力进行研究，可以减少研究区土壤的破坏程度，只要前期充分展开相关指纹电荷工作研究，制作图谱，后期研究则只需取少量土壤测定土壤pH值后查询前期土壤指纹电荷图谱即可得出某时段内土壤养分保持能力的变化趋势：通过对重庆南平镇石庆村人为生态恢复区不同土壤利用方式下前后一年土壤样品的分析，得出退耕后撂荒草地土壤的各项养分保持指标含量增长最快，对恢复土壤退化程度最为有利，其次是杉树林和樟树林；而从人为生态恢复的各种利用方式来看，花椒林土壤的养分保持能力最好，土壤退化恢复的程度最快，其次是金银花和桃林。
