12, cilantro is a kind of umbrella flower family plants, rich in essential oils, aroma, but the essential oils are very volatile, and can not withstand a long time heating, cilantro is better to add before eating, in order to retain its aroma.
13, when the high temperature washing or drying program, do not touch the door glass, so as to avoid burns. When taking out the dried clothes, be careful of metal parts on the clothes, such as zippers and buttons, to avoid burns.
14, if the collar and cuffs are dirty, you can put the clothes into the warm water dissolved with washing powder to soak for 15-20 minutes first, and then wash them normally, and they will be clean.
15, how to use the casserole: casserole soup, stew, to put water in the casserole, and then put the casserole on the fire, first with the fire, and then with the fire.
16, cooking vegetables, add some diamond starch, so that the soup becomes thick, not only can make the cooking out of vegetables delicious, and because the starch containing glutathione, vitamin protection.
17, rice if burned paste, hurry to turn off the fire, put a piece of breadcrumbs on top of the rice, cover the pot, 5 minutes later, the breadcrumbs can be absorbed by the paste.
18, the amount of laundry detergent: if the clothes are not too dirty or wash too much foam, then to reduce the amount of detergent. Avoiding overuse of washing powder not only saves money and protects the environment, but also makes the washing machine more durable.
19. When cooking dumplings, add enough water, add 2% salt after the water boils and dissolve the dumplings, which will increase the toughness of the gluten, and the dumplings won't stick to the skin and bottom, and the color of the dumplings will become white, and the soup will be clear and fragrant.
20, many people love to eat vegetables but do not love to drink vegetable soup, in fact, when cooking, most of the vitamins have been dissolved in vegetable soup. For example, after the cabbage is fried, there will be 70% of vitamin C dissolved in the vegetable soup.

1, the principle of ultrasonic metal welding is the use of high-frequency vibration waves transmitted to the two metal surfaces to be welded, under pressure, so that the two metal surfaces rubbing each other to form a molecular layer of fusion between the advantages of fast, energy-saving, high fusion strength, good electrical conductivity, no sparks, Close to cold processing; disadvantages of the welded metal parts can not be too thick (generally less than or equal to 5mm), the weld bit can not be too large, the need for pressure.
2, the advantages of welding:
1), the welding material does not melt, not fragile metal properties.
2), good conductivity after welding, resistance factor is extremely low or nearly zero.
3), the welding metal surface requirements are low, oxidation or plating can be welded.
4), welding time is short, without any flux, gas, solder.
5), welding without sparks, environmental protection and safety.
3, ultrasonic metal welding applicable products:
1), nickel-metal hydride batteries nickel-metal hydride batteries nickel mesh and nickel sheet mutual fusion and nickel sheet mutual fusion.
.2), lithium batteries, polymer batteries, copper foil and nickel sheet fusion, aluminum foil and aluminum sheet fusion.
3), wire intermelt, bias knotted into a strip with multiple intermelt.
4), wire and the name of the electronic components, joints, connectors melt each other.
5), a variety of home appliances, automotive products, large heat sinks, heat exchange fins, honeycomb heart of the inter-fusion.
6), electromagnetic switches, non-fusible switches and other high-current contacts, the mutual fusion of dissimilar metals.
7), metal pipe sealing, cut off can water, airtight.

Vertical grinders are easier to load and unload. Manual loading and unloading eliminates the need to support the workpiece while starting the chuck. The operator simply mounts the workpiece downward into the chuck. Centering the workpiece also occurs more naturally because there is no uneven gravity when the jaws are closed.
Loading and unloading with a crane or manipulator may also be made easier because the workpiece in the chuck has the same stable positioning on a slewing car or transfer plate. For example, a disk-shaped part like a gear can be conveyed horizontally downward for pickup and installation. Similarly place it horizontally down in the grinder's chuck.
Vertical grinders are also typically more compact than their horizontal equivalent. Vertical grinders take up more height space with a smaller footprint. This leaves room for an automatic loader or robot alongside the machine, making automation a more attractive option.
This drawing shows how ID and surface grinding can be performed in a single setup when the grinding spindle is mounted on a rotating hex tool holder.

Superconducting magnets made by using superconducting currents to generate a magnetic field come in a variety of forms, such as hollow superconductors that can be used as magnetic shields, and cylindrical magnets, toroids, and saddle coils. In line with the performance requirements of the magnet, such as the choice of materials, manufacturing process, they can withstand the critical current, the magnetic field strength, low AC losses and stability issues need to be considered. Superconducting magnets in physics, physics, biology and medicine and other research and applications have played a corresponding important role.
Superconducting magnets, such as Nb3Sn in the 88kOe magnetic field can also withstand a current of 105A/cm2, such magnets can be used for high-energy gas pedals, controlled thermonuclear reactions, magnetic fluid power generation, superconducting motors, energy storage, magnetic levitation devices, etc., is the conventional magnets can not be compared to, such as the small size, lightweight, and in the superconducting state of work without energy, so the power consumption is much less than conventional magnets. So the power consumption is much less than conventional magnets, but the function is much bigger. Because of the need to work in the critical temperature Tc below, so need to have to keep the temperature below Tc refrigeration equipment.

The term refers to devices capable of controlling thermal contact or thermal separation between two objects, and there are generally the following four types:
1) Gas switch: two objects that are not in contact with each other, if they are in a high-vacuum environment, each other's heat transfer is extremely poor, and it is a thermally separated . State, after filling a small amount of helium, through the helium heat transfer, the two objects between the realization of thermal contact, thus playing the role of thermal switch.
(2) mechanical switch: there are two kinds of clamp and plate type. With and A object thermally connected pincers clamp B object when the thermal connection, pincers release when the thermal separation. Plate type can be used bellows or Wilson joint expansion and contraction with the A object thermally connected to the plate and the B object thermal connection or separation. In order to minimize thermal resistance on contact, a metal plate with high thermal conductivity such as silver, gold or copper should be soldered on the contact.
(3) superconducting switch: a thermal switch made by utilizing the difference in thermal conductivity between the superconducting state and the normal state of a superconducting material. Normal state thermal conductivity n is proportional to T, superconducting state thermal conductivity s is proportional to T3, so n/s is proportional to T-2, the thermal conductivity ratio of up to 103 ~ 105 in the following 0.1 K. Its normal and superconducting state of the switch between available to a small magnet to realize. At low temperatures the material is in a superconducting state, plus a magnetic field when it is transformed into a normal state, so you can use the magnetic field to control the thermal switch on and off, i.e., A, B, two objects through a superconducting material is connected together, no magnetic field, the material thermal conductivity of the thermal conductivity of the small is a thermal open circuit. Add a magnetic field, the material lost up to normal state, thermal conductivity increased by several orders of magnitude to become a thermal path.
(4) magnetic thermal switch: the use of some materials such as Be, Ga, etc., the heat flow of the magnetic field effect, that is, under the action of the external field, the thermal conductivity of these materials is small, no external field when the thermal conductivity is large. So you can use the magnetic field to control the heat path or disconnect. For example, high-purity Be single crystal in T20K, H = 6kOe, its thermal conductivity ratio (0)/(H) 102, this thermal switch in the temperature rise after its phonon transport heat flow overrides the carrier transport heat flow, which is insensitive to H time. So this thermal switch cannot be used at T100K.
