FR conjugate gradient methods with perturbations are proposed. The global convergence property of the first method is proved under the condition of main directions' sufficient descent. Whereas, in the proof of the convergence for the other two methods, we only need main directions' descent. Importantly and quite interesting, boundedness conditions such as objective function being bounded below, boundedness of level set are not needed. Chapter 5 presents a version of Dai-Yuan conjugate gradient method with perturbations.

在主方向充分下降的条件下证明了第一个方法的全局收敛性，而后两个方法的收敛性是在主方向下降的条件下证明的，这些收敛性证明的一个共同特征就是不需要目标函数有下界或水平集有界等有界性条件，第5章采用Wolfe或Armijo步长规则提出了带扰动项的Dai-Yuanabbr。

方法①参照NCCLS M27A方案中的微量液基稀释法测定柠檬醛和氟康唑对原始白念珠菌的最低抑菌浓度和最低杀菌浓度；②采用多步诱导法，观察在含梯度浓度(1～50MIC)柠檬醛培养基上连续转种的白念珠菌MIC的变化情况，以氟康唑作为阳性对照，同时设空白对照和溶媒对照；③将敏感性下降的诱导株在无药培养基上连续转种10次后，检测其MIC值；④测定柠檬醛对氟康唑敏感性下降诱导株的MIC值。

The invention relates to an amplifier circuit containing a high-frequency transistor (1) and having a circuit (2) for adjusting the operating point, which provides a base current for the high-frequency transistor (1) according to the voltage released at a resistor (3) which is connected in the collector ring of the high-frequency transistor (1). The circuit (2) has a differentiating unit (20), fed by the supply voltage, which compares the voltage released at the resistor (3) with a reference voltage.

Magnetic transmission power with increasing temperature is a continuous decline in the curve, usually the work of extreme temperature in the magnet below the decline of its transmission capacity is reversible, but above the limit temperature is irreversible, that is, magnetic cooling After the loss of transmission capacity can no longer be resumed.

磁钢传递的功率随温度的升高是一条连续下降的曲线，通常，在磁钢工作极限温度以下，其传递能力的下降是可逆的，而在极限温度以上则是不可逆的，即磁钢冷却后，丧失的传递能力再也不能恢复。

Listed companies in the manufacturing sector is the largest listed companies in Shanghai group of companies covering more than half of listed companies in Shanghai, from the overall perspective, the manufacturing sector in 2008 listed companies in the first three quarters year-on-year revenue 28% growth in net profit year-on-year increase of 16%, but the third quarter revenues increased 22 percent year-on-year, performance actually fell 16 percent,"Made in China" is facing a substantial decline in the performance situation.

制造业上市公司是全球最大的上市公司在上海的面积超过了上市公司在上海的一半集团公司从总体上看，2008年制造业中列出的今年前三季度公司同期收入的28％，净利润同期增长同比增长16％，但第三季度的收入增长了百分之二十二去年同期相比，性能反而下降了百分之十六，"在中国制造"正面临重大在性能下降的情况。

The property of the algorithms on linear problems is studied and the Broyden's methods have been proved that they are not descant. More precisely, the distances between the sequences obtained by solving the linear problems and the solutions of the linear problems do not decrease under any vector norm.

笔者研究了将该方法用于求解线性方程组时的内在性质，否定了一个自然的推测，指出它在解线性方程组时不是一个下降的算法，即所得到的点列与方程组的解之间的距离在任何向量范数意义下都不具有单调下降性。

On the basis of two criteria of stomatal limitation of photosynthesis suggested by Farquhar and Sharkey,the re-dominant limiting factor of photosynthesis is stomatal conductance of stomatal limitation in the forenoon,but the midday depression of photosynthesis at noon and the decrease of photosynthesis in the afternoon are the results of low carboxylation efficiency of the mesophyll leaf.

根据Farquhar和Sharkey的观点，造成净光合速率下降的原因既有气孔限制又有非气孔限制因素，上午净光合速率下降的主要是由气孔限制因素造成的，午间和下午光合速率的降低则主要归因于叶肉细胞羧化效率的降低。

The Lace-up group's center of pressure displacement quantity is bigger than other two groups,therefore its balance ability is also bad, therefore suggested the athlete when wearing ankle braces sports should inquire specialized doctor and the protection suggestion avoids injury.

人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时， Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果，但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象，造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大，著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大，且Lace-up组在著地期压力中心偏移量也较其他两组大，故其平衡能力也有差异，故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。

Raman spectra indicate a lower density of phonons of nano-samples than that of a bulk one.

在Raman谱上观察到的散射峰强度随颗粒度减小而下降，即声子密度下降的效应，也可以归功于表面态和界面态上未能形成完善的晶胞，晶格振动的格波难以形成。

The thermal gradients of the depression decreased during the Cenozoic time. However, it decreased quickly in Eogene, but only changed a little during the Neogene period The thermal gradient was 540～500℃/km during the period of the Kongdian group deposition, 500～400℃/km during the period of Shahejie group, 400～385℃/km of Dongying group and 385～355℃/km during the Neogene.

研究结果表明，济阳坳陷新生代以来的古地温梯度是逐渐降低的，但在早第三纪时期下降的幅度较大，而在晚第三纪－第四纪则下降的幅度明显较小；济阳坳陷在孔店组沉积时期的地温梯度为540～500℃/km之间，沙河街沉积时期为500～400℃/km，东营组沉积时期为400～385℃/km，晚第三纪时期为385～355℃/km，第四纪以来基本未变。
