The OSIRIS telescope is a Three Mirror Anastigmat consisting of conic surfaces: a concave hyperbolic primary, a convex parabolic secondary and a concave spherical tertiary.

OSIRIS 望远镜是一个三反射系统，由一个凹双曲面主镜，一个凸抛物面次镜和一个凹球面三镜。次镜 M2在中间，主镜 M1和三镜 M3呈离轴配置。

In the First Prayer Book the Communion service is styled "'The Supper of the Lord and the Holy Communion, commonly called the Mass"; in the Second, and also in the present book,"The Order for the Administration of the Lord's Supper, or the Holy Communion".

在第一次的祈祷书共融服务是冠之以"'晚饭的主及圣餐，俗称地下"，在第二次，也是在本书"，并下达了行政主的晚饭，或圣餐"。

According to theory analysis and example computation, the following conclusions are obtained.1. During the analysis on the cable shape in the suspension bridge"s completion state, the pre-displacement of saddle and the case that the cable and stiff girder commonly bear the second-stage dead load should be considered.2. When supposing the construction ideal initial state in the first time, if the initial state model is established according the cable"s span central sag in the bridge"s completion state, and the reasonable correction formulation is created in the iteration process, the result can converges fast.3. The cable shape in the bridge"s completion state is not parabolic, nor catenary. It is between parabola and catenary. Actually it is funicular polygon closer to the catenary.

通过理论分析和实例的计算表明：1在悬索桥主缆成桥线形分析过程中，须考虑主塔鞍座的偏位以及二期恒载由主缆和加劲梁共同承担的实际情况；2在第一次假设施工理想初态时，以成桥状态已知的主缆跨中垂度建立施工理想初态模型，同时在迭代计算的过程中，建立合理的修正公式，才能使收敛的速度快：3在成桥状态时主缆的线形既不是抛物线，也不是悬链线，而是介于抛物线与悬链线之间，更接近于悬链线的索多边形。

It was to remind Peter of the terrible self-confidence in which he had said:"Though I should die with Thee, I will not deny Thee"; of the need of quiet, deep heart-searching ere he could be sure that his love was real and true; of the need of deep penitence in the consciousness of how little he could trust himself; and then of love being the one thing needful for the full restoration to his place in the heart of Jesus, the first and highest condition for feeding His sheep and caring for His lambs.

其实这是提醒他曾自信满满地说：「主阿！我就是同祢下监，同祢受死，也是甘心。」（路廿二33）。主耶稣问他三次，就是要他自躬反省，对主耶稣的爱是真实不改变的吗？然而事实证明遇到考验时，人的软弱会显露无遗，人的承诺是靠不住的。要如何弥补人一时的软弱跌倒呢？唯一的方法就是餵养主耶稣的羊群，才能恢复他在主耶稣心中的地位。

Open Linear Encoder includes main grating scale and optical encoder head. This optical encoder head includes LED light source, optical detector module, and secondary phase-grating. LED light will pass through the plano-convex lens and produces parallel light. As the parallel light pass through secondary grating, the quadratic image display on the main grating scale. And the Moire interference will be reflected from the main grating scale and detected by optical detector module, as there is a relative shift between the main and secondary grating. From detecting the periodic sinusoidal signal with phase difference 90°, the period represents the grating pitch, using the counter to detect the number of periodic signals to get the displacement, and we can adapt the technology of electron subdivide further to increase the resolution of measurement .

反射式光学尺包括主光栅尺及光学读头，光学读头包含LED光源、光侦测器模组及相位式副光栅，LED光源经平凸透镜，产生平行光穿透副光栅后，副光栅之二次成像投射在反射主光栅尺上，当主、副光栅因相对运对产生之Moire干涉经主光栅尺反射至光电检测器，检出相位差90°之周期性弦波讯号，其周期代表栅距，因此可用计数器检出周期性讯号数目得到位移量，可进一步采用电子细分割技术提高解析度。

The new method gives out a set of equations based on the fundamental algebra rules that principal stress trace obeys and the essential attributes it possess, we then combine these equations with further information described in this paper leading to an exact description of the conic representing the principal stress traces.

该方法是根据主应力迹线满足过任意三条等倾线的主应力都可以用二次曲线来描述这一条件，再利用主应力迹线本身所具有的性质列出方程组解算出描述主应力迹线的一元二次方程，然后根据方程描绘出所求的主应力迹线。

The shaker includes a dual mass flywheel and the rotate and pendulum driven mechanism; in the rotate and pendulum driven mechanism, the rotary cylinder body of the rotatable hydraulic rotary cylinder (8) is connected with the sub flywheel (15) connecting with the main flywheel (13) and a rotary cylinder shaft (4) at the same side through a transmission sleeve (11) connecting to the rotary cylinder right end cover (9); a torsional transducer (10) and a turbulence iron core of an angular sensor (12) are arranged on the sub flywheel shaft, a winding of the angular sensor is positioned on the transmission sleeve fixedly connected with the main flywheel.

该激振器包括双质量飞轮及其旋转和扭摆驱动机构；所述旋转和扭摆驱动机构，其旋转液压摆缸(8)的摆缸体通过与摆缸右端盖(9)相连的传动套(11)，在同侧与主飞轮(13)和与摆缸轴(4)相连的次飞轮(15)相连接；扭矩传感器(10)及摆角传感器(12)的扰流铁芯装在次飞轮的轴上，摆角传感器的线圈装在与主飞轮固连的传动套上。

In the region upstream of vortex breakdown, the sectional streamlines emanating from the leading edge spiral inward to primary vortex and in the region downstream of the breakdown, on the other hand, the streamlines separating from the leading edge are not entrained into the vortex core in the instantaneous sense. Along the axis, the topology of the primary vortex alters several times starting from stable focus near the apex to unstable focus, and lasts back to stable focus near wake edge, the stable hmit cycle and unstable limit cycle are shown in this evolution.

发现在截面流线谱中，即使奇点的类型、数目及位置相同，奇点的连接方式也有可能不同；旋涡破裂点前，主涡由来自前缘的力线卷绕而成，主涡焦点与前缘半鞍点相连，旋涡破裂后，来自前缘的力线不再卷入主涡，主涡焦点与对称面上的鞍点相连：在流体由翼尖流向后缘的过程中，截面流线谱的拓扑结构发生了多次变化，主涡焦点相继由稳定状态转变为不稳定状态，最后又转化为稳定状态，并先后出现了稳定的极限环及不稳定极限环。

And yet the Lord was not doubtful of Peter's love, for each time He followed up His question with a fresh Apostle commission; but now that He put it for the third time, Peter would have the Lord send down the sounding-line quite into the lowest deep of this heart:'Lord, Thou knowest all things, Thou perceivest that I love Thee!

然而，耶和华也不怀疑彼得的爱情，每一次他跟进他的问题一个新的使徒委员会，但现在，他把它为第三次，彼得将有主传送下来，冠冕堂皇的线相当纳入最低的深部，这心：'主啊，你knowest所有的东西，你perceivest ，我爱你！

This entirely studies long end effect is by " even the line " Chris Anderson of magazine chief editor puts forward the earliest in the Changweiyiwen October 2004, use descriptive such as the commerce of Yamaxun and website of Netflix and so on and economic mode, still do not have official definition up to now, the most extensive multitude using in the website is SEO personnel, they are being searched a few not be too popular keyword do not look down upon these keywords, the one discharge that decides keyword of dimensions to bring is to exceed likely advocate of the discharge of the keyword, divide up in a few big doors advocate keyword market we should monarch additionally path, searching competition is not so big keyword, spin these keywords like the tail, grow gotten flow what pull more more, besides SEO, in growing end effect to return body to show to wait for network business in B2C, C2C, B2B, product of an unexpected winner is searched in the commodity with intense competition, seek much site, spin the tail, can increase a sale so.

长尾效应这一概念是由《连线》杂志主编Chris Anderson在2004年十月的长尾一文中最早提出，用来描述诸如亚马逊和Netflix之类网站的商业和经济模式，至今尚无正式定义，在网站中应用最广泛的人群是SEO人员，他们在寻找一些不是太热门的次关键词别小看这些关键词，一定规模的次关键词带来的流量是有可能超过主关键词的流量的，在一些大门户瓜分的主关键词市场我们应该另辟蹊径，寻找竞争不是那么大的次关键词，将这些关键词像尾巴一样拉长，拉的越长得到的流量越多，除了SEO外，长尾效应还体现在B2C、C2C、B2B等网商中，在竞争激烈的商品中寻找冷门产品，找多点，把尾巴拉长，这样就能增加销售。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。
