An iterative factorization method based on linear subspace for projective reconstruction is presented in the paper. It relies on the facts that the rows in the matrix including all the image points span the same linear subspace as the rows in the matrix including space points and the fact that any basis of the subspace can be regarded as projective reconstruction. The projective reconstruction and the depth factors are obtained based on linear iteration.

摘要该文提出了一种基于子空间线性迭代的射影重建方法，该方法利用所有的图像序列构成的行向量生成的线性子空间之和与射影重建结构点构成的行向量生成的子空间是同一线性子空间及在该子空间中任何一个基底都可以作为射影重建的特性，线性迭代地求取射影重建及图像深度因子。

The relationships of the loop length, stitch density and thickness of fabrics to yarn linear density were analyzed with the experiment data, and the fiber volume fraction of glass fiber plain knitted fabrics was estimated theoretically.

采用改变纱线根数的方法，利用横机编织了多种不同纱线线密度的玻璃纤维纬平针织物，并改变编织的弯纱深度，得到3种弯纱系列的试验用布20块。

In this paper, an improved sensorless control strategy, which is based on the detection of zero crosspoints of back-EMF, is proposed. In this method, only one feed back signal is needed to sense terminal voltages and no motor neutral line is required. The phase shifter errors in traditional methods are eliminated.

本文同时提出了一种改进的无位置传感器检测方法，这种方法基于反电势过零点检测的基本原理，采用单路位置反馈信号，无须引出电机中性线，硬件结构简单，消除了传统检测方法中由于深度滤波产生的相移和误差。

He post-Ted Koppel version of ABC 's "Nightline" is winning over audiences by mixing the familiar -- a trademark in-depth report -- with lighter fare aimed at younger viewers.

ed Koppel 之后， ABC 新版的《夜线》节目以年轻观众为收视对象，通过将大家所熟悉的——标志性深度报道——与轻松的话题结合在一起，赢得了观众的喜爱。

From the amount of things to do in the game, offline and online, to the depth of it.

OTOH, if the remaining search depth is too low, and many threads are already searching the tree, there is no meaningful way to go in and help to get the result quicker.

另一方面，如果剩下的搜索深度太浅，而且很多线程已经在搜索，那么就没有什么有意义的方法能够快速得到结果了。

Because RFCA in a bipoiar fashion can enlarge lesion surface area without increasing the depth, and its particular lesion distributions involved the electrode/tissue interface and the part between the two adjacent electrodes, there is much opportunity to hit the target in bipolar fashion so long as the orientation of the pathway or the any part of reentant circle is not parallel to the electrode-connecting line, whatever at any angle.

因为双极消融法比常规单极消融法有更大的消融面积但不增加深度，而且其组织损伤分布于两电极与组织的交界面和两电极之间区域，所以只要旁道或折返环路的任何部位的走向与两电极的连线不相平行，在任何夹角下双极消融均比单极消融有更多的击中机会。

By Visual Basic 6.0 program, taken the distance between hole 200mm and buried depth 120～150mm as the optimization goal, the most optimum parameters range of the mechanism was obtained as follows: the initial angle between planet frame and the line formed from spraying-fertilizer needle-tip and planet wheel axle was -45°～-40°, the initial angular displacement of planet frame was 40°～50°, the distance between spraying-fertilizer needle-tip and the planetary gear axle center was 280～300mm, simultaneously, the semi-major axis of elliptic gear was 29.364mm, the teeth quantity was 23, the ratio of semi-minor axes and semi-major axis was 0.958, the radius of circular gear was 25mm.

对该机构进行运动学分析，建立了数学模型，以穴距200mm和入土深度120～150mm为寻优目标，应用Visual Basic 6.0软件编程得出满足机构运动要求的最优参数范围为：喷肥针尖和行星轮轴连线与行星架的初始夹角-45°～-40°、行星架初始角位移40°～50°、喷肥针尖与行星轮轴心距离280～300mm，此时椭圆齿轮长半轴29.364mm、齿数23、短半轴与长半轴比0.958，正圆齿轮半径25mm。

Plimsoll line waterline, usually refers to the summer load line ship, with S said that ships with the maximum draft is the depth of the region in summer.

Plimsoll line 吃水线，通常指船舶夏季载重线，用S 表示，表明船提出与夏季区域是最大吃水深度。

It is promising in industrial scatheless inspection, architectural quality inspection, underground conduit quality inspection, underground archaeology. Traditional appeared form of TEM inversion interpretation is horizontal -slice image, vertical slice image or compounding-slice image.

传统瞬变电磁法反演解释的表现形式是采用平面图和剖面图或组合剖面图进行表达，只能反映某一层面(某一深度上或者某一测线上)的电阻率变化。
