The invention relates to a method for synchronizing at least one node of a bus system, which is operated with a predeterminable system clock period, whereby a local clock period and a reference clock period are given for the at least one node, and the reference clock period is synchronized with the system clock period. A local clock period, which is synchronized with the system clock period, of the at least one node is produced whereby linking the local clock period with a splitting factor, whereby the splitting factor represents a ratio of the reference clock period to the local clock period. The splitting factor for synchronizing the local clock period with the system clock period is adapted by adding or subtracting a adaptation value.

用于同步至少一个总线用户的方法，所述的总线系统用可预定的系统周期运行，由此为该至少一个用户给定局域时钟脉冲周期和基准时钟脉冲周期并且把局域时钟脉冲周期与系统时钟脉冲周期同步，其中通过把局域时钟脉冲周期与分配系数相关联的方式产生同步到系统时钟脉冲周期的、至少一个用户的局域时钟脉冲周期，其中，分配系数说明基准时钟脉冲周期与局域时钟脉冲周期的比例，其特征在于，通过加或者减一个适配值或者说补偿值，对用于把局域时钟脉冲周期与系统周期同步的分配系数进行匹配。

BMD measurement of femoral neck without external reference phantom based on QCT data is an effective and feasible method, both MVM and LVM selected as internal reference is more convenient and has no difference comparing with erector spinae as internal reference.

The speed-sensorless vector control and the identification of motor parameters in this paper are the two novel research of vector control.Using asynchronous machine's mathematic model in three-phase static reference frame, this paper has derived it's mathematic model in two-phase static reference frameand in two-phase rotating reference frame, and got the coordinate transformance formulus based on the constant magnetic force and power force, by compared different field orientation methods, we can find that field orientation at rotor field can realize the decoupling of the stator current flux component

无速度传感器矢量控制和电机参数辨识是矢量控制的两个新的研究方向，本文利用异步电机在三相静止坐标系下的数学模型推导出两相静止坐标系、两相同步旋转坐标系下的数学模型，根据磁动势守恒和功率守恒的原则，得出各坐标变换公式；通过不同磁场定向方式的比较发现，异步电机按转子磁场定向时定子电流励磁分量和转矩分量可以比较方便地实现解耦。

Reference frame's uniformation methods, adjustment methods and the implication of corresponding datum for various adjustment methods are systematically discussed about high precision GPS network. The systematical investigates on the choice of reference station in the high precision GPS data processing and the effect to adjustment results are made. Some general principles on the choice of reference station are presented.

Common rolling plank is shown intense (orientaton of 0002) tool reference plane, after rolling of horn waiting for diameter, plank grain orientaton by original (change of orientaton of 0002) tool reference plane is; of orientaton of blame tool reference plane the existence after strain crack of common rolling plank is many twin brilliant, amount of brilliant of twin of drawing of direction of rolling of edge of plank of rolling of horn w

普通轧制板材呈强烈的(0002)基面取向，等径角轧制后，板材晶粒取向由原来的(0002)基面取向转变为非基面取向；普通轧制板材拉伸断裂后存在大量孪晶，等径角轧制板材沿轧制方向拉伸孪晶数量明显减少，等径角轧制有可能启动了新的滑移系，而拉伸孪生只是作为一种协调变形机制。

该站点是一个地球科学数据门户网关，它由德国Goettingen州立大学图书馆创建的，它详细的介绍了许多的关于地球科学和地理学的网站，它的内容大多是面向大学生水平的。

The Ancient library of Alexandria The ancient library in history.

古代的亚历山大图书馆在历史的古老的图书馆。

It's warning and outcry for mediocrity of human society by the superiority.Under the surrounding, The library can put a good equitant development into execution dependent upon whether the leader have a "sage jewel" of scientific decision making to understand and exert it's great signification poignantly.He delve library science and acquaint with professional skill, we can get a lot of practical experience from ancientness and today,Chinese and foreign. At the present time,run back over historical development of libary's management, getting a realization on property of common service and roles definitely.

在这样的大环境下，任何一个公共图书馆能否实现跨越式良好发展，这就要看领导者是否能以科学决策理念为"法宝"，深刻理解科学决策的重大意义并能在理论和实践创新中很好地掌握和运用决策理念的主要内容；是否能在图书馆学科理论研究的工作实践中，以图书馆学科体系为科学决策的理论基础，深入了解和研究图书馆学的形成和发展史、学科体系及分支学科、研究方法及其前景展望等，从而为科学决策在本专业学科领域的研究创新打下坚实的理论基础；是否能通过纵横分析人类文明历史进程中公共图书馆的基本职能及其演变过程，更加明确其职能的公益性质，从而树立起以最大可能实现公共图书馆的职能为成功决策的实践标准。
