The biconditional markers can he placed at equal or unequal intervals according to train positioning precision, and they may encode the positions of the complete rail track or only a section between two balise devices.

二值标记可以根据列车定位精度的需要等间隔或不等间隔布置，既可以对整条轨道线路统一编码，也可以与既有应答器相结合应用，每段应答器之间的轨道线路采用相同的编码。

The train positioning technology based on absolute position encoding is proposed. The absolute positions of the rail track are encoded with the m sequence. The biconditional markers placed on the rail track are detected sequentially by the train-borne reader. The exclusive position code consists of the binary information in the shift register. The absolute train positioning information can be extracted by decoding this position code.

利用m序列（最大周期线性反馈移位寄存器序列）对轨道线路上的绝对位置进行编码，当列车在线路上运行时，通过车载阅读器顺序检测设置在轨道线路上的二值标记，在不同位置上读到的标记在移位存储器中构成唯一的位置编码，以此位置编码值作为地址与车载阅读器所处位置的坐标信息相对应，就可以实现列车的绝对定位。

The line is divided into blocks and each block is protected by a signal but, for metro, the blocks are shorter so that the number of trains using the line can be increased.

线路被分成几块而每一块由一个信号保护。但是，对地铁来说，区块之间的距离更短以使得使用这条线路的列车数量得以增加。

Through analysis of the layout and the characteristics of the loads in the factory, the proper measuring devices and positions are selected. The voltage and current on bus bar are obtained by measuring the device parameters in the line.

本文通过对该铝厂线路及负荷特征的分析，在选择了合适的测量仪器和测量地点后，实地测量了线路中的设备参数，获得了母线电压、电流的实测数据。

Keep input traces away from output traces to minimize capacitive coupling of interference between input and output sections.

布线时，让输入线路和输出线路尽可能地远离，可让输入输出侧的偶合电容最小化。

According to characteristic of model parameters, direction criterion based on model parameter identifying is proposed to decide the direction of faults.

本文提出了一种新的基于模型参数识别的快速方向元件，即将线路分别等效为R-L模型、T模型和Π模型，然后建立相应线路等效模型下区内、区外故障时的数学模型，利用最小二乘法求解模型参数—系统电阻R和系统电感L，根据得到的模型参数的特性，构造出基于模型的参数识别方向判据，从而判断出故障的方向。

The characteristic of power transmission line project is a large investment, a long construction period and technological complexity.

输变电线路工程项目具有工程耗资大、建设周期长和技术复杂的特点，所以输变电线路工程的建设具有高风险性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
