“暖气片好还是地暖好？”这个问题在大概十几年前，曾经大量出现在北方人口中——那时地暖刚刚兴起，几乎所有用户都在纠结这个问题。现如今南方地区的朋友家里也装起了暖气，地暖渐渐地向南方发展，于是这个问题改成南方朋友问了。那么究竟暖气片和地暖有哪些优缺点呢？哪个更适合我们的家呢？地暖地暖更好——这个答案几乎已经被所有北方用户认可了，这就导致南方用户盲目跟风。但是地暖真的适合南方用户吗？地暖优点1.舒服：地暖是从脚部发热，整个房间的温度由下而上逐渐升温。

　　电线电缆工业界中的聚氯乙烯(PVC)即是其中的一例，至今仍在护套和绝缘料中承担着主要角色。随着社会的进步和科学技术的飞速发展，PVC内在的弱点(燃烧时释放的大量烟雾，严重的腐蚀性气体和有毒气体)益发明显。

450/750 v polyvinyl chloride insulated control cable, applicable to dc and ac 50 hz, rated voltage 450/750 v power plants, power plants, factories, mines, ports and petrochemical enterprises such as long-distance control loop, as a connecting line between electrical instrumentation and automation instrumentation, phoresy all kinds of electric energy role, make the whole electric, reliable operation.
The advantages of electric cable are more and less. Generally, it is buried in the soil or laid in indoor, ditch, middle, line insulation distance is small, no tower, little, basically no surface space. High reliability. It is less affected by climatic conditions and surroundings, and has high transmission performance and reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less work. Less likely.

Computer shielded cable; Purpose: high voltage insulation with small interface constant. Use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure form, with a small dielectric loss, the transmission ability is strong, resistant performance is good wait for a characteristic, can reliable transmission weak analog or digital, can be widely used in electricity, metallurgy, petroleum, chemical, textile sites detection and control of the door or by computer automation instrumentation, and general industrial computer. Relevant technical indicators: reference BS5308 IEC189 and British second, product code 1 and code the DJ - (series code) electronic computer shielded cable Y - (insulation code) high-pressure polyethylene F - (insulation code) fluoroplastic V - (sheath code) polyvinyl chloride (R - said many strands of soft wire core P - (block code) copper mesh shielding P1 tin plated copper mesh shielding P2 copper tape screened P3 aluminum-plastic composite membrane shielding for example 1:3, product specifications order 7 (14) to 1.0 was computer shielded cable can be represented as: (1) total shielding DJYVP7 * 2 * 1.0mm2 (2) partial shielding multiple strands of soft line DJYPVR7 * 2 * 1.0mm2 (3) total shielding type DJYPVP7 * 2 * 1.0mm2 Type (1) packet shielding DJYPV3 x 3 x 0.75 was (group 2) screen a total screen DJYPVP3 x 3 x 0.75 was three, model name and use range model name using range DJYVPDJYPVDJYPVP total shielding polyvinyl chloride polyethylene insulating sheath computer cable shielding polyvinyl chloride polyethylene insulation group sheathed electronic computer cable shielding total shielding polyvinyl chloride polyethylene insulation group sheathed electronic computer cable 1, fixed for laying indoors, in cable trench or pipe 2, cable long-term working temperature: - 20 ℃ + 65 ℃, the cable laying temperature is lower than 0 ℃, the bending radius should not less than 10 times of cable diameter DJYVPR DJYPVR DJYPVRP total shielding polyvinyl chloride polyethylene insulating sheath computer with a soft cable shielding polyvinyl chloride polyethylene insulation group sheathed computer with a soft cable shielding total shielding polyvinyl chloride polyethylene insulation group with a soft cable sheath computers shows that: (1) flame retardant cable (oxygen index greater than 30) need to add code "out" in front of the model. For example, zr-djypv zr-djypvp et al. (2) armored (steel belt armored) cables need to add code "22" in the lower right corner of the model, such as: DJYPV22 djypvpppvp22, etc. The cable is mainly used for ac or dc 300V or below and can work normally when 500V or below.

串联型稳压电路有放大和负反馈作用的串联型稳压电路是常用的稳压电路。它的电路和框图见图4。它是从取样电路（R3、R4）中检测出输出电压的变动，与基准电压（VZ）比较并经放大器（VT2）放大后加到调整管（VT1）上，使调整管两端的电压随着变化。如果输出电压下降，就使调整管管压降也降低，于是输出电压被提升；如果输出电压上升，就使调整管管压降也上升，于是输出电压被压低，结果就使输出电压基本不变。在这个电路的基础上发展成很多变型电路或增加一些辅助电路，如用复合管作调整管，输出电压可调的电路，用运算放大器作比较放大的电路，以及增加辅助电源和过流保护电路等。
