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

自交和杂交琯溪蜜柚果皮中的过氧化氢酶活性呈下降的趋势，四季柚前期上升，后期下降；而果肉中的CAT活性变化是自交琯溪蜜柚呈下降趋势，杂交琯溪蜜柚和四季柚前期上升，后期下降。

The effects of different plant densities on flag leaves chlorophyll content,SOD activity and MDA content after anthesis in stronggluten wheat interplanted in paddyfield were studied.

本试验在江苏淮北地区设计不同密度试验，研究其对稻田套播强筋小麦花后剑叶叶绿素含量、SOD酶活性和MDA含量的影响，结果表明：随花后生育进程推移，叶绿素含量呈下降趋势，且随密度增加，下降幅度增大；花后单茎干物质积累量和单茎籽粒产量亦随密度增加而下降，二者呈极显著负相关；随花后生育进程推移，剑叶SOD酶活性呈单峰曲线变化，可用二次曲线方程模拟，在花后1416 d达峰值，且随密度增加峰值出现时间提前，峰值数值呈先上升再下降的变化特征；随花后生育进程推移，剑叶MDA含量呈上升的变化特征，且随密度增大，数值变大；花后35 d剑叶SOD酶活性与花后单茎干物质积累量和单茎籽粒产量呈极显著正相关，而MDA含量与花后单茎干物质积累量和单茎籽粒产量则呈显著或极显著负相关。

However, 74% of farmers need to increase appliction of fertilizer for wheat when measure agronomic efficiency.

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 different methods of blood pressure measurement and vital microcirculation observation method were used . The systemic blood pressure, arteriolar and capillary blood pressure decreased significantly after 3 months of Linzhi administration in addition to the routine hypotensor in 27 cases of refractory primary hypertension.

Meta-analyses showed that the response rate of TP (topotecan + cisplatin) regimen had no significant difference compared with EP regimen (etoposide + cisplatin) with OR 0.83 and 95%CI 0.63 to 1.09, but myelo-suppression such as leucopenia and thrombopenia was more severe with TP regimen; the response rate of monotherapy with topotecan was similar with that of CE (carboplatin + etoposide) regimen with OR 0.59 and 95%CI 0.22 to 1.60; the response rate of TEP (topotecan + etoposide + cisplatin) regimen was comparable with that of EP regimen with OR 1.37 and 95%CI 0.82 to –2.28, but myelosuppression and anemia were more severe with TEP regimen; the response rate with OR 0.97 and 95％CI 0.60 to –1.57, median time to progression with WMD –2.32 and 95％CI –5.72 to 1.09 and median survival time with WMD –1.65 and 95％CI –7.13 to 3.83 of IV topotecan were similar to those of oral topotecan, while neutropenia was more severe with IV topotecan.

Meta-analysis based on included studies showed that response rate of TP regimen has no statistic significance compared with EP regimen[OR0.83,95%CI(0.63-1.090)],but myelo-suppression such as leucopenia and thrombopenia is more severe; response rate of single topotecan has no statistic significance compared with CE regimen[OR0.59,95%CI(0.22-1.60)]; response rate of TEP regimen has no statistic significance compared with EP regimen [OR1.37, 95%CI(0.82-2.28)], but myelo-suppression such as leucopenia, thrombopenia and anemia is more severe; response rate of IV topotecan has no statistic significance compared with Oral topotecan[OR0.97, 95%CI(0.60-1.57)],so as median time to progression[WMD-2.32, 95%CI(-5.72,1.09)] and median survival time[WMD-1.65, 95%CI(-7.13,3.83)],while neutropenia is more sever in IV topotecan than Oral topotecan.

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.

结果：绝经妇女脂联素水平与体重指数、腰臀比、空腹血糖、空腹胰岛素、LEP、TG、极低密度脂蛋白胆固醇、胰岛素抵抗指数、体重、腰围、体脂含量、体脂百分比显著相关；瘦素水平与BMI、WHR、FINS、LEP、TG、HDL-C、VLDL-C、载脂蛋白B、apoA1／apoB、腰围、FM、％F等指标显著相关；多元逐步回归分析显示LG10、COS和腰围是基线脂联素水平的预测变量，而％F，apoB和WHR是基线瘦素水平的预测变量；在肥胖前期，脂联素、瘦素已经出现明显不良变化，同时也伴随着体成分、空腹血糖和血脂的异常；运动实验后，两个运动组的FM、％F、体重、WHR、FPG、TG都显著下降，而HDL-C显著上升；AER组瘦素显著下降，而AER+RES组则没有显著变化；两组的胰岛素和HOMA-IR水平都有显著下降；对照组所有指标都没有明显变化；尽管运动后脂联素水平没有显著变化，但是脂联素变化量与％F、WHR和血糖变化量显著负相关，而且如果按照运动后体重下降的程度比较，则体重下降大(≥3kg)的受试者比下降小的(≤0kg)脂联素水平有明显升高；运动后瘦素水平的变化量与％F，WHR及体重的变化量显著负相关。

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.

结果表明：'紫柄籽银桂'种子不耐脱水，种子生活力随着含水量的下降而降低，种子含水量下降到11.6%时，生活力仅为6%；自然脱水过程中，种子细胞膜系统受到损伤，相对电导率不断上升；种子内SOD活性随着含水量下降而呈总体下降的趋势；POD先呈波动性上升，脱水12 h时达到最大值，之后急剧下降。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
