The research results indicate that the interface between weld and l2Crl MoV steel is the weakest part of welded joint. However ,the interfacial failure tendency of low match welded joint is less than those of medium and high match welded joint.

试验结果表明，焊前预热250℃，焊后回火750℃×1h，加速模拟运行500h后，高匹配和中匹配接头的力学性能劣化明显，界面蠕变损伤及失效倾向较大；而低匹配接头的力学性能优于高匹配和中匹配接头，界面蠕变损伤较轻，失效倾向较小。

The experimental results show that at a constant system pressure, the weight percent of millets distributed into the collector B (connecting with the moving branch) decreases with increasing superficial air velocity with a constant angle betwe...

试验结果表明，在发送压力基本保持不变的条件下，当活动支与主管间夹角不变时，分配到活动支侧收料仓B的固相颗粒质量分数随表观气速的增大而逐渐减小；当活动支与主管间夹角发生改变时，分配到收料仓B的固相颗粒质量分数随夹角的增大而逐渐减小，且相较于表观气速，活动支与主管间夹角的变化对分配到收料仓B的固相颗粒质量分数影响较大。

The all-purpose 2.8- to 12-millimeter IR varifocal lens provides the proper field of view for most surveillance applications. The 2.9- to 8.2-millimeter IR varifocal lens features aspherical optics to provide a fast F1.0 maximum aperture for best low-light performance.

多功能的2.8至12mm红外变焦镜头为大多数监视应用提供了适当的视场角。2.9至8.2mm红外变焦镜头以非球面光学为特色，为最佳低光性能提供了高速的F1.0最大光圈。

In this dissertation, the nonlinearity of the MOS varactors caused by the large output signal of the DCO, as well as its influence on the performance of the DCO, is analyzed. A back-to-back in series digitally controlled MOS varactor is presented to avoid the nonlinearity of the varactors of the DCO.

对DCO大信号工作时所引起的数控MOS变容管的非线性以及这种非线性对DCO性能的影响进行了分析，提出了改善这种非线性的背靠背串联数控MOS变容管的新结构，可以使DCO的相位噪声最多降低8.1dB。

The research results indicate that the qualities of the Jurassic reservoir are dominated by construction. Good reservoirs lie to an advantaged nose protrusion, nearly relating to the distribution of sedimentary micro-facies. The reservoir that lies on the main position in the riverway has better gathering characters. Because argillaceous content is increase and the porosity and permeability became smaller, the character of the reservoir becomes bad in the flood plain area that lies on the skirted riverway and between riverways. Characters of the layer relate to the distribution of main sand-body that the better feature of the layer and the bigger thick of sandbody layer.

通过综合储层含油性、非均质性、分类研究的GIS 分析结果，研究认为：长西油田侏罗系储层性质受构造控制，储集性好的储层在区域上大多属于一个有利的鼻状隆起；且与沉积微相的展布密切相关，在河道主体部位的储层其储集性一般都较好，而在河道侧缘和河道之间的泛滥平原沉积区，泥质含量增加，孔渗性变差，储层的储集性也变差；储层优劣与主砂带的分布也有关，砂层厚度越大，储集性越好。

Chinese dragon is of magic power. It can change the length of its body as it wishes, it can either fly or swim and it can even bring rainfalls.

中国龙是神奇的，本领大，它能变长也能变短，能上天也能入海，它还能在天上兴风降雨。

More accurate crystallographic parameters and improved mathematical model were used in simulating the formations of 3D plate-shaped or 2D lenticular-shaped Ni4Ti3 variants.

与二维模型相比，本研究采用了准确的晶体学参数及改进的数学模型，获得了更为直观及合理的三维盘状变体及二维透镜状变体； Ni4Ti3沉淀相的长度、宽度和面积分数随时间的变化分别遵循指数、线性和对数关系；且其长度与宽度的比值并非恒定值，在生长初期该比值有较大的增速而随后逐渐减慢，能很好地解释沉淀相盘状及透镜状形貌特征形成的原因并与相关实验结果吻合。

Mr. Thoreau explained to the President that the railroad had destroyed the old scale of distances,--that the library was useless, yes, and President and College useless, on the terms of his rules,--that the one benefit he owed to the College was its library,--that, at this moment, not only his want of books was imperative, but he wanted a large number of books, and assured him that he, Thoreau, and not the librarian, was the proper custodian of these.

梭罗向馆长解释：现在火车已摧毁或扩大了借阅距离，----图书馆也就变得无用，是的，馆长和大学也就变得无用，在他自己看来，这所大学唯一对他的用处就是它的图书馆，----眼下，他不但是急用这些书，他还急用更大数量的书，而且梭罗向馆长保证，他，梭罗，而不是管理员是这些书的合法看管人。

Secondly, the structure and operating principle of imitation of the wind turbine based on DC motor were formulated and the control strategies were introduced.

第三，用Ansoft仿真软件建立了风力机模拟和SRG系统的仿真模型，分别对风力机特性的直流电动机模拟系统和SRG开环系统、电压闭环系统的建压过程及变负载、变转速动态过程、SRG风力发电系统最大风能追踪控制方案进行仿真分析，结果与理论吻合较好。

On condition that the nonlinear uncertain functions are gain bounded, a sufficient condition, which is dependent on the maximum value of the time derivative of time-varying delay, is presented for the existence of the controller.

在非线性不确定性满足增益有界条件下，得到了该类时变时滞系统依赖於时变延迟导数的最大值的满足鲁棒性能的一个充分条件。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
