Examination found a number of major quality problems: First, part of the observed deformation and deformation measurements are not laying a solid reference point, deformation monitoring points do not comply with regulatory requirements; deformation observation, the calculation is not strictly enforce the state standards, such as the base network is not on a regular basis retest , no point will work in conjunction with the reference point for measurement, the standard of measurement stations and other allowable error overrun.

检查中发现了一些主要质量问题：一是部分变形观测与形变测量项目基准点埋设不稳固，变形监测点设置不符合规范要求；变形观测、计算未严格执行国家标准，如基准网未定期复测，未将工作基点与基准点进行联测，水准测量测站限差超限等。

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.

基于QCT数据应用CAD无体模软件具有与有体模方法和DXA方法相同的测量BMD的能力，其中采用便捷的股内侧肌、股外侧肌作为内部参考具有与竖脊肌相近的结果，能够为医生提供BMD的参考信息，可用于骨质疏松的诊断、健康普查。

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.

系统地讨论了高精度GPS网数据处理中参考框架的统一方法、平差方法及各种平差方法所对应基准的意义，针对高精度GPS数据处理中基准站选取对平差结果的影响进行了系统地分析，提出了基准站选取的一般原则。

After pointing out its superiority and deficiency, the article finally puts forward several suggestions to the development of digital reference service in library, including making criterion of aptitude of reference librarian, creating assistant forum service, importing appraise system that user is leading, reinforcing general adoption of the market principle for reference service.

在介绍商业网站非赢利性参考咨询服务概况的基础上，分析其非赢利性、受众的广泛性、用人制度的灵活性、服务方式的单一性和咨询内容的百科性等特点，指出它所具有的优势和存在的不足，最后提出发展图书馆数字参考咨询服务的几点意见，包括规范参考咨询馆员资质；推出辅助性质的论坛服务；引入以用户为主导的评价体系和适时加强参考咨询服务的市场化运作。

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。
