Black wire to the negative terminal of the battery.

原处，并重接黑线到电池负极。

Is L1,L2,L3,N,PE.open the control-box the confirm,in control-box, connected the yellow green line is the grounding PE .3 black lines togother is null line N,for the machine must connect the Nnull line

接电源的工业插头按插头上标号接上对应电线，即L1，L2，L3，N，PE。打开控制箱门确认，控制箱内连接黄绿线的是地线PE，3根并在一起的黑线是零线N。本机必须连接N线。

Now connect the red wire to the positive terminal of the volt meter, and the black wire to the negative (or "common") terminal of the volt meter.

现在连接红色线，以积极的终端的Volt米，黑线，以负面终端的Volt米。

This one seems suggest 补 only to avoid the relativly risker procedure.

还有，昨天看牙医生说我有两颗智齿正在坏，特点就是上面有黑线，她说可以补也可以拔，我在美国拔过一颗智齿，当时美国医生也建议我全拔掉，目前这些智齿还没有给我带来麻烦，不知道该不该拔。

Of road with metal sensor,and measures ...

路面黑线及障碍物，使用金属传感器检测路面下金属铁片，应用光电码盘测距，用光敏电阻。。。。

AT89C51 single-chip microcomputer is used as the test and control core of the intelligent robot in this design,which detects the black line and barrier on the surface of road with infrared photoelectric sensor,and detects iron piece beneath the surface of road with metal sensor,and measures range with photoelectric yard measure,tests and judges the garage position with photoresistor,and also dynamically controls rotating direction and speed of motor by PWM(Pulse-Width Modulation) technique.

本设计以AT89C51单片机作为智能机器人的检测和控制核心，采用红外光电传感器检测路面黑线及障碍物，使用金属传感器检测路面下金属铁片，应用光电码盘测距，用光敏电阻检测、判断车库位置，利用PWM技术动态控制电动机的转动方向和转速。

The roles and economic significance of four rodents (Phodopus roborovskii,Dipus sagitta,Meriones meridianus and Crivetulus barabensis) inhabiting in Erdos sandland were evaluated from the point of energy flow and material cycle.

摘 要：以鄂尔多斯沙地中的4种主要啮齿动物小毛足鼠、三趾跳鼠、子午沙鼠和黑线仓鼠为对象，从能流和物质循环的角度对其在生态系统中的地位、作用及其经济意义进行了定量评价。

C. gloeosporioides mycelium grew well on media with fructose and glucose as carbon source while sorbose and starch promoted sporulation. The mycelia of C. dematium grew well with maltose as carbon source while starch promoted sporulation. Of the nitrogen sources tested, organic nitrogens were beneficial for both mycelial growth and sporulation but chemical nitrogens suppressed both growth and sporulation.

供试碳源中果糖和葡萄糖有利于胶孢炭疽菌的菌丝体生长，山梨糖和淀粉有利于其产孢；麦芽糖有利于黑线炭疽菌的菌丝体生长，淀粉有利于其产孢；氮源中有机氮有利于2种炭疽菌生长和产孢，化学氮源则表现抑制作用。

The optimum temperatures for mycelial growth, sporulation and spore germination of C. gloeosporioides was 28℃, 28℃, and 28℃, respectively and those of C.

胶孢炭疽菌菌丝体生长、产孢和孢子萌发的最适温度都为28℃，黑线炭疽菌的分别为25，28和25℃。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
