With the reform experimental unit's pulsion of state-owned business bank stock system, how to establish an efficient governing organization of joint-stock company after stock recombination, how to draft rational responsible division, power allocation and interest adjustment system, how to deal with the entrust after the separation of ownership and managerial authority—the agency relationship, become the focus which theory world and bank worker are concerned with.

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 this paper also shows the structure and parameters of the optical system. The Xenon light of super high voltage is used as interferential source. The position of it is on the focus of the reflector of ellipsoid surface. After reflecting, its lights form a collective point . This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.

该光学系统选用超高压氙灯作光源，使其位于椭球面反射镜的一个焦点上，发出的光线经椭球面反射后所形成的汇聚点与准直负透镜组的物方焦点重合，光束经准直系统后变为平行光束，此平行光束再经库德反射镜和特殊发散棱镜系统，形成具有3°发散角的发散光束，用来干扰敌方设备。

美元兑日圆汇价在攀升后略后回落，主要由于投资者把焦点集中于双赤庞大的问题，以及经济前景日益欠明朗所致。

So the defocus quantity is calculated by detecting the image spot position offset and the front focus plane of the collimation lens can be adjusted on the first image of the theodolite.

该方法利用半反半透镜将准直物镜后的物光折转，采用双分离透镜将目标成像到CCD上，经视频驱动、放大电路、再经A/D转换后输入到微机进行图像信号处理，这样，通过检测像的偏移量求出离焦量的大小和方向，然后驱动调焦部件使准直镜的前焦点在经纬仪的第一像面上。
