This paper analyzes the trends and variations of cross-section profile parameters in lower Yellow River with the methods of time series analysis. The analysis results show that since 1950s, cross-section profile parameters in lower Yellow River have change with trend, especially after 1990s, the bankfull discharge and bankfull area all show decreasing trends at all the four stations. The bankfull width at Huayankou, Gaocun and Lijin station and the average depth at Huayuankou and Aishan station and the maximal depth at Gaocun station show decreasing trends while the bankfull water level at Gaocun and Aishan station and width-depth ratio at Aishan station show increasing trends.

RESULTS: Compared with SG, the levels of Cr and BUN and that of MDA in the nephric tissue were significantly higher than those in OG and TM+OG. The levels of these indices in TM+OG were lower than that in OG. The level of GSH in OG and TM+OG was lower than that in SG, but higher in TM+OG than in OG.

However, the Oestradiol level of RSA patients was lower than non-pregnancy women obviously. CD4+CD25+Treg of normal pregnancy women (early pregnancy, mid-pregnancy and late pregnancy) were higher than non-gestation women obviously. CD4+CD25+Treg were at peak in mid-pregnancy. The CD4+CD25+Treg were obviously lower in RSA patients than non-pregnancy women.

早、中、晚孕组外周血CD4+CD25+Treg细胞数均明显高于正常非妊娠组（t值分别为2.22，8.9，5.91，P均＜0.05），中孕组明显高于早孕组（t=6.31， P＜0.05），晚孕组略低于中孕组，但差异无统计学意义；反复自然流产组明显低于正常非妊娠组（t=8.07， P＜0.05）。

Its leakage current is lower than 5nA at room temperature. The quantum efficiency in the wavelength range of 400-500nm is about 83%. The junction capacity is about 110-120pF. The noise level of PIN+PreAmp system is lower than 527e at -25C. The PIN diodes have passed the long-term stability test. All the main performances of our PIN diodes meet the requirement of ALICE/PHOS,and some of them are even better.

The edgewise technique was used to align and level the upper and lower arches gradually and upright the lower incisors. Then, modified LeFort Ⅰ osteotomy was operated with 4 cases pterygomaxillary disjunction and the other 2 cases not. The maxillas were not moved during the operation and sutured mucoperiosteum at the same place. After 3-5 days latency period, elastic distraction about 700g/side and increasing to 1400g/side gradually, was started with two cases which the maxillas were not cut off totally.

Test results show 1 the fatigue strength of peened joints under overloading, in spite of lower than the fatigue strength of the non-overloading peened joints, is still greatly higher than the fatigue strength of as-welded joints; 2 In the range of lower stress level and longer life, ultrasonic peening method exhibit better results than TIG dressing; 3 Fatigue strength of the welded joints with defects (such as undercut at the weld toe) can also be improved greatly after peening treatment.

结果表明，超声冲击处理过的焊接接头经过载后疲劳性能有所下降，但与原始焊态相比提高疲劳强度、延长疲劳寿命的效果仍然十分显著；在低中应力水平、中长寿命区域，使用超声冲击法提高焊接接头疲劳强度比TIG熔修法效果更好；超声冲击处理后，含咬边等缺陷的焊接接头，疲劳强度同样有较大的提高。
