A class of conjugate descent algorithm with single parameter βk for unconstrained minimization problems is presented and it is proved that this algorithm is of descent feature when it satisfies the condi- tion of a sort of inexact linear searching and, in addition, it is globally convergent.

给出了无约束问题一族含有一个参数βk的共扼下降算法，证明了该共扼下降算法在满足一种非精确线性搜索条件时是下降的，而且是全局收敛的。同时可以看到共扼下降算法是其特例

然而从1998年开始，我国小麦播种面积连续下降，2005比1997年下降了24%，总产下降了21%[1]，是近些年粮食产量下降的主要原因。

AT-deficient plasma had significantly smaller R values compared with control, and dilution did not change R values in AT-deficient plasma. Celite activation eliminated dilution-associated changes in R values in control plasma but resulted in linear decreases R(2 = 0.88-0.96, P 0.0001 in alpha, A, and G in response to dilution.

结果显示对照组稀释后R、A、G值均明显下降，a值没有改变，而AT缺乏组与相应对照组相比R值明显降低，但稀释对其R并没有影响，硅藻土激活后使对照组中稀释造成R值下降的效果被消除，但使a、A、G值随稀释程度呈线性下降。

The program of AER+RES was similar to AER, but went through resistance exercise 20min in base section of every exercise trail.Result: Prior to intervention, adiponectin levels were significantly correlated with BMI、 WHR、 COS、 LN、 LN、 TG、 LG10、 LN、 weight、 waist、 FM、%F, and leptin levels were significantly correlated with BMI、 WHR 、 LN 、 LN 、 TG 、 HDL-C 、 LG10、 apoB 、 apoA1/apoB、 waist、 F1M、%F. Stepwise multiple regression analysis revealed that LG10; COS and waist was an predictor of basal adiponectin levels , and %F,apoB and WHR was an predictor of basal leptin levels. In early obesity, adiponectin and leptin can be worsened , along with the changed of body component, fasting plasm glucose and lipid accumulation. After intervention, both group were significantly reduction in FM,%F,weight, WHR,FPG and TG, while HDL-C had significantly increased.AER exhibited significant in leptin, while AER+RES did not show the change. Insulin and HOMA-IR were changed in both groups. The control group exhibited no significant change in any variables. Although adiponectin levels were unchanged in the three groups, a significant negativecorrelation between delta %F, delta WHR and delta FPG was observed. Futhermore, if compare the degree of delta weight, we fought a significant increased in adiponectin between the group of delta weight higher (=3kg) than delta weight lower(=0kg), delta %F, delta WHR and delta weight were significant negative correlation with delta leptin.

The results showed that O. fragrans seeds were desiccation-sensitive as the seed viability declined to 6% when the seed moisture content was reduced to 11.6%. The seed electrical conductivity increased with the declining moisture content, a sign, which was caused by increasing cell membrane cleavage. Superoxide dismutase activity decreased rapidly during desiccation; but peroxidase activity increased to the maximal value when dehydration for 12 h, then declined rapidly when seeds were dehydrated more than 12 h.
