同时双向的

This kind of challenges are of complete bearings,and are also of two-way at the same time.

这种挑战是全方位的，同时也是双向的。

On the base of the single-diameter laser-scanned measuring technology, a double direction laser-scanned measuring system is presented. Which combinate the laser-scanned measuring technology with special optical system. In the system, the collimation semiconductor laser-scanned beam scanning two perpendiculars direct of one plane of the measured workpiece at the same time is made. The beams with the dimension information of two perpendiculars direct are processed by the scanning receive system, the high-speed photoelectric transition and electronic data process. Two measured results of the diametric directs and ellipse tolerance,etc, parameter, of the turning workpiece on the same plane are obtained by non-contact automatic measurement. The problem of non-contact measurement of two perpendiculars direct of one plane of turning workpiece is settled. It processes many peculiarities, such as high speed, high accuracy and non-contact automatic measurement, etc.

I have to skip other popular terms such as joint tenancy and prenuptial agreement among others due to lack of space, I believe the purpose of marriage, if only seeking for one-way benefits instead of two-way, will not work out properly, that should apply to both in business world and in our private life.

我要跳过其他热门网站如联合租赁和婚前协议等，由于缺乏空间，我相信，为了结婚，如果只追求单向有好处，而不是双向的，不行的话，应同时适用于商业世界，在我们的私人生活。

The bi-directional cross track scanning, attitude fluctuation and the ETM+ sensor itself of Landsat7 result in the geometrical distortions including underscan, overscan and misalignment, which make geometric calibration more difficult than other kinds of model. The complicated imaging model increase the difficulty of geometric calibration as well.

Landsat7的双向扫描模式、姿态波动和增强型专题制图仪ETM+(Enhanced Thematic Mapper+)传感器本身的特点等必然导致遥感图象的几何畸变，同时复杂的成像几何模型也增加了几何校正的难度。

FYB---double-direction angular contact thrust ball bearing is a bearing unit composed of an integral outer ring, a group of sectile inner rings, steel balls, cage assemblies and sealing.

FYB—双向推力角接触球轴承是由一整体外圈、一组剖分式内圈、钢球和保持架组件及密封组成的轴承单元，其结构紧凑体积小，可双向受力，旋转精度高，并可在承受很高径向负荷同时承受一定的轴向负荷。

Also, based on the security of CPK algorithm, the method is sufficient for privacy and unforgeability in realizing mutual authentication in mobile IPv6 networks.

同时基于CPK算法的安全性，提出的方案在有效实现用户和网络的双向认证的同时可以保证私钥的保密性和签名的不可伪造性。

Therefore,the concept of person-organization fit has become an important concept when enterprise enlists an employee.

但是，在企业的实际运作中我们看到，企业的招募过程其实是个双向的概念，当企业在寻找合适员工时，员工也在选择合适的企业，所以企业与个人同时都以选择合适的对方为主要目的。

In another words, Philo spoke out the contents of the Bible in Greek philosophical terms and made Judaism Hellenized; at the same time, he also judaised the Greek thought. This is a bi-direction process. At last he made faith and reason syncretize together.

或者说他用希腊哲学术语和词汇把圣经的内容展现出来，把犹太教希腊化，但同时，他又把希腊哲学犹太化，这是一个双向的过程，从而达到信仰与理性的融通。

Afterwards,this paper presents typical station type selecting model by taking unidirectional three-stage/three-yard Marshalling station and bidirectional three-stage/six-yard Marshalling station as representation.At last,northern Xuzhou is applied to a numeral example to validate the effect of this method,which proves that station type selecting by means of comparing the total waste of wagon flow in the Marshalling station from the view of wagon flow structure is not only effective but scientific,meanwhile,this provides a scientific and effective decision-making measure for determining the scope and layout of Marshalling station.

在上述研究基础上，以单向三级三场和双向三级六场为代表，构建能力约束条件下的典型单双向系统的择优比对模型，并通过徐州北编组站进行实例验证，从中看出，从车流结构入手，根据各种车流在编组站所消耗总费用的高低来进行站型选择不仅切实有效，而且经济科学，同时，这也为全面定位编组站的规模和布局提供了一种科学有效的决策手段。
