Spring Health: Eat 7 types of food to make you healthier

There are no drugs that keep people healthy, but there are foods that make people eat healthier. The following 7 kinds of foods allow us to eat younger and younger in 2011, and eat more and healthier. Eggs: Studies have shown that eating an egg every morning not only does not increase cholesterol, but also allows people to consume less calories throughout the day, unconsciously reducing

When the semiconductor diode is turned on, it is equivalent to the switch closing (circuit is turned on), and when it is turned off, it is equivalent to the switch opening (circuit cut), so the diode can be used for switching, and the commonly used model is 1N4148. Since the semiconductor diode has a unidirectional conduction characteristic, the PN junction is turned on under a positive bias, and the resistance in the on state is small, about several tens to several hundreds of ohms; in the reverse bias, it is off. The resistance is very large. Generally, the silicon diode is above 10 Μ Ω, and the bismuth tube is also several tens of kilo ohms to several hundred kilo ohms. With this feature, the diode will act as a control for the current to turn on or off in the circuit, making it an ideal electronic switch.
