The approach comprises following steps: grouping available measurements in various possible subsets, solving target position in Cartesian co-ordinate corresponding to each measurement subset, selecting several subsets with higher accuracy of position location, fusing the data of target-position corresponding to subsets selected by step .

The US Food and Drug Administration has issued an alert that some patients may experience severe and possibly incapacitating musculoskeletal pain while taking bisphosphonates, notes Business Week , carrying an Associated Press wire story."Although severe musculoskeletal pain is included in the prescribing information for all bisphosphonates, the association between bisphosphonates and severe musculoskeletal pain may be overlooked by healthcare professionals, delaying diagnosis, prolonging pain and/or impairment, and necessitating the use of analgesics," the FDA says in a statement on its Web site.

经济周刊相关报社火线故事报导，美国食品药物管理局已经发出一项警讯，部分病患在使用双磷酸盐药物时，可能会发生严重与可能是使肌肉无力的肌肉骨骼疼痛；FDA在网站上的一项声明指出，虽然严重肌肉骨骼疼痛包含在双磷酸盐药物的处方资讯中，但双磷酸盐药物与严重肌肉骨骼疼痛之间的关连可能被健康照护者所轻忽，因此造成延迟诊断、延长疼痛以及或是损伤时间，并且使得病患需要使用止痛药物。

Front-peak dominated double peak mode and double peak group mode were mainly found in the rain-particle samples, while the front-peaked dominated double peak group mode is mainly found in the rain-particle samples ofdry-season, and double peak group mode is mainly found in the rain-particle samples of wet-season.

正构烷烃分布模式呈现一定季节变化，干季雨水主要为单峰态模式分布，而平台型模式主要出现在春季的雨水中，夏季雨水则三种模式都有；干季雨水颗粒物主要为双峰态前峰型模式，而湿季则以要双峰态双峰型模式为主。

This paper discussed the properties and the key technology of materials, warp-knitting and finishing; The geometry model and mechanical model of the bi-axial warp-knitted fabrics were firstly put forward according to practical products in this paper, which consider the effect of the ground structure especially.

本文详细讨论研究了经编双轴向立体骨架织物生产所采用的原料、经编织造及后整理工艺的特点和技术关键，为该类织物生产提供了一个详细的工艺开发和生产流程；本文结合经编双轴向立体骨架织物产品的实际情况，首次设计了经编双轴向立体骨架织物的线圈几何模型。

Young's two slits interference of discrete double light source is numerically simulated,and the curve of visibility, curve of light distribution and interference pattern are solved with different type of line and line width.

对分立双谱线光源的杨氏双缝干涉进行模拟，求解出不同线型和线宽时干涉条纹的可见度曲线、光强分布曲线和干涉图样，用直观的计算机图形说明了分立双谱线的线型和线宽对干涉条纹的影响。

However, there is no such restriction on the transformational forms, such as the Dative Construction in English and the sentence marked by "ba" in Chinese. The differences are: Chinese DOC has a more wide-ranging scope; Some verbs used in the Chinese DOC sentences are inherently one or two-place, but verbs used in the English DOC is at least inherently two-place, can't be one-place; some verbs bearing the same meaning can construct a DOC sentence in Chinese but not in English, and vice versa; there are differences on the form, the position and the ellipsis of the double objects; there are differences on the passive form of the DOC in both languages.

其不同点有：汉语的双宾结构范围更广；汉语中有的动词可能是一价或二价，但英语中的动词起码是二价，不可能是一价；有些具有相同意思的动词在汉语中可以构成双宾结构，在英语中则不能；反之亦然；在英汉语中，间接宾语和直接宾语的构成、省略及位置上都存在差异；英汉语的双宾结构的被动式形式存在差异。

Analysis indicates that there is little difference in the displacement of tunnel and well control of stratum displacement by both methods. Plastic zone develops more obviously above the tunnel side by CRD method and is larger by CRD method than by dual sidewall guide pit method. It is comparatively obvious that the plasticity district develops in the side direction of the tunnel by dual sidewall guide pit method and the leading influence distance is also longer than that by CRD method. The development speed of plasticity district is comparatively fast in the range of the leading 3~6 m in CRD tunnel and 0~3 m in sidewall guide pit tunnel. There are different advantages by both methods for passing through sand layer.

结果表明，采用这2种工法时引起的隧道变形相差不是很大，都能较好地控制地层的变形；采用CRD法时产生的塑性区较双侧壁法大，且向隧道侧上方发展较为明显；采用双侧壁法时产生的塑性区在隧道侧向发展较为明显，超前影响的距离也大于CRD法；采用CRD法时的塑性区在超前3~6m的范围内发展速度较快；采用双侧壁法时的塑性区在超前0~3 m的范围内发展速度较快；对于隧道穿越砂层而言，2种工法各有优势。

It features big needle stitch, thick sewing material, high rotating speed, pressure-foot revival dual feed, bisynchronous feed for up feed, needle stem thread picking, bend needle drawing, eccentric positioning of principal axis, mechanical full-automatic lubrication to increase speed, ensuring the quality and prolonging the lifetime, making the material neat and regular with good-looking thread stitch and even needle pitch.

其特点：针距大，缝料厚，转数高，采用单压脚上下复活式双送料，双同步，上送料为双牙齿送料，针杆挑线，弯针勾线，主轴偏心定位，机械式全自动供油全润滑，提高速度，保证整机质量，延长使用寿命，使制品整齐，针距均匀，线迹美观牢固。
