By weakening the premise of the convexity of the objective function required in paper[7], we prove the sufficient desent property and the global convergence with the strong Wolfe line search.

在第二章中，我们参照文献[7]中的方法，提出了一类与HS算法相关的共轭梯度算法，并减弱了文[7]中要求目标函数二阶连续可微且为凸的前提条件，采用强Wolfe线搜索，在较弱的条件下证明了这一类算法具有充分下降性和全局收敛性。

In allusion to the defect of grads descension of traditional back propagation network algorithms, some improving measures such as adaptive learning and additive momentum has been taken, and better application result is acquired.

针对基于梯度下降法的BP网络存在的学习效率低、收敛速度慢、易陷于局部极小状态、网络的泛化及适应能力较差等缺陷，采用了附加动量法及自适应学习率、合理选择激励函数等策略对算法中的缺陷给出了改进措施，取得了较好的应用效果。

After so many years the rural senior high schools have got great triumphs in College Entrance Examination, but the hard working made the low quality and the disparagement of the teachers\' and students\' life, leading to some tragedies of anticipation of today with the losing of tomorrow.

几年来，县中模式在取得了高考的辉煌的同时，它所采取的"死揪政策"和"魔鬼教育"也导致了师生生活质量的下降和生命意义的贬损，发生了许多为了今天而失去明天的人间悲剧。

The landscape architect pruned around specimen trees , removing the tertiary branches to create a visual corridor downslope and allow more sunlight to reach the ground cover layer .

景观设计师剪除了周围的树，剪掉了一些不重要的枝干，创建了一个下降的视觉通道，并使地面的植被能够接受到更多的阳光。

The migration of carbonate breccia wedge also reflects the shifting of the platform margin and the relative sea level changes . Among them , the Guli breccia wedge extended the furthermost distance to the platform , which represents that the platform margin shifted to the platform for the furthermost distance .

碳酸盐岩角砾岩楔的位置迁移反映了台地边缘位置的迁移和海平面相对变化幅度的大小，其中谷立角砾岩舌相对于其他角砾岩楔向台地方向延伸距离最远，代表了台地边缘位置向台地方向迁移的距离最大，张家湾角砾岩楔代表了安尼初期的海平面快速下降。

The migration of carbonate breccia wedge also reflects the shifting of the platform margin and the relative sea level changes. Among them, the Guli breccia wedge extended the furthermost distance to the platform, which represents that the platform margin shifted to the platform for the furthermost distance. The Zhangjiawan breccia wedge represents a rapid sea level falling in the Early Anisian.

Numerical tests are also conducted to investigate the microphysical effects to the mesocale convective systems. The evaporation of raindrops can strengthen the surface "cold pool" to decease the temperature of rainfall center. The condensation of vapor can lower the air pressure and increase the convergence and updraft so that the convective echo develops stronger. The melting of graupel can cool the air to restrain the convective activity. The falling of precipitation particles can increase the downdraft and induce the outflow nearly the surface. The effect of condensation is the most important among all the microphysical processes. It can change the whole structure of cloud system.

微物理过程对对流系统发展和维持有重要作用：强降水的雨滴蒸发过程会加强"冷池"效应，同时增强了雨带南侧原有的地面中尺度辐合线；凝结潜热在低层诱发了与回波相应尺度的中尺度低压，增强了辐合和上升运动，促进对流发展；霰的融化吸热通过冷却大气会不利于气压下降、气流辐合抬升等过程，降低对流不稳定能量，减缓对流发展；重力拖曳使气块冷却降温，降低对流不稳定能量，并且使低层的气压升高、气流辐散，在近地面附近产生出流，加强地面中尺度辐合线的强度。

Fish of sprouted broad bean group had higher FEAA, TFAA, hardness and gumminess than those of immersed broad bean group.

结果表明，配合饲料组、浸泡蚕豆组和发芽蚕豆组草鱼的增重率分别为83.08%、55.01%和62.82%，饵料系数分别为2.03、2.96和2.70，投饲浸泡蚕豆或发芽蚕豆显著降低了草鱼增重率(P.05)，增加了饲料系数(P.05)；与配合饲料组相比，浸泡蚕豆组和发芽蚕豆组草鱼肌肉粗脂肪含量和肌肉失水率显著降低(P.05)，胶原蛋白含量和肌纤维直径显著增加(P.05)；肌肉游离氨基酸中呈味氨基酸的含量显著下降(P.05)，而必需氨基酸含量显著增加(P.05)；肌肉的硬度和黏性也有了显著提高(P.05)。

The Catholic Church's 1758 Index of Prohibited Books omitted the general prohibition of works defending heliocentrism,[39] but retained the specific prohibitions of the original uncensored versions of De revolutionibus and Galileo's Dialogue Concerning the Two Chief World Systems .

天主教会的1758指数违禁图书省略了普遍禁止工程捍卫heliocentrism ， [ 39 ] ，但保留了具体禁止未经审查的原始版本者revolutionibus和伽利略的对话两个主要世界体系。这些禁令终于下降到了1835年指数

After introducing to the inner structure and the driver timing of a interline area-CCD KAI-1010M briefly,a high speed and low cost CCD driver circuit used in digital space survey camera was designed in a new way.

介绍了行间转移面阵CCD芯片KAI-1010M的内部结构和驱动时序，采用新方法和低成本器件设计了该CCD芯片的驱动电路，把电源和电机控制的脉冲宽度调制技术引入CCD驱动电路，采用超高速运放驱动高速负压信号以减小其上升沿和下降沿时间，达到高速低成本驱动要求，解决了驱动设计中的技术难点。
