Probably the nightmare is from the move began, the work has been very tired, just want to live comfortably after work, to the various koi for good luck, really please. 1 thought that the decoration in advance of the settlement of accounts can rest, the facts tell me too naive, everyone is waiting for a year before the car sales miss busy burst, I also want to handle the new house account migration procedures, move to a new home all relatives and friends to celebrate dinner, weekend two days tired.
I'll go, too>, keep only frequently used items to reduce clutter. Find a home for small items Wireless cardboard box : Find a fixed storage location for small items such as keys, mobile phones, PDAs, such as drawers or cartons, so that they can be found quickly and reduce time waste.
Develop the habit of regular cleaning, timely disposal of unwanted items, and keep the desk clean and orderly. This can not only improve the efficiency of learning, but also make the mood more comfortable.
Keep your desk organized by laying books flat on the table and stacking them neatly on the tableA corner of. One advantage of this method is that it does not interfere with the normal use of the table, while leaving another corner for stationery. Place books vertically to form stacks at right angles to your desk. This will allow you to stack more books and make your desk look cleaner and more organized.
1, prepare emergency tools: prepare some emergency tools for the family, such as flashlights, spare batteries, fire extinguishers, fire extinguisher use guide, etc. Secure doors and Windows: If the doors and Windows cannot bearIn the event of an earthquake, measures should be taken to reinforce doors and Windows or replace them. Keep in touch: Ensure that family members keep in touch with each other, obtain earthquake early warning information in time, and take appropriate actions according to the requirements of early warning information. In the face of the threat of natural disasters, when earthquakes occur, we need to have a clear preparation strategy to ensure the safety and survival of ourselves and our families. The first priority is to stock up on the necessities of life: food and water: dry food, canned food, energy bars and other easily preserved foods are the first choice, and at least 2 liters of drinking water per person per day is guaranteed for at least 3 days.
3, can be at home oneTwo goldfish, these creatures can warn us of early signs. Having a dog at home can help by barking at night. At home, under the bed, around the table can be placed two bottles of mineral water and some dry food for emergency needs, usually under the bed will not be found, do not think that this measure silly, at least it can help you live for a few days until you are found.
4, in daily life, what preparations should be made for the prevention of earthquakes? Prepare enough food and water, emergency medicine and emergency lighting tools. Check and promptly eliminate the hidden dangers of adverse earthquake protection at home, and strengthen housing: take a look at yourselfThere is no adverse seismic housing local housing construction quality is good whether it has been disrepair and should not be strengthened to evacuate in time.
5, first of all, we must exclude the suspended objects in the indoor height, the items placed vertically on the cabinet and the wooden frame, change their placement and mode, so that it is not easy to shock down and hurt people. And remove all flammable and explosive materials. Move the bed away from the window. Put shatter-proof tape on the Windows. Keep the shockproof kit in an easy to grab place.
6, before the earthquake, you should ensure the safety of your family, hiding under tables and other strong furniture. Small shaking in the early stages of an earthquakeWhen moving, take immediate action, duck under the table, and firmly hold the table legs. If there is no shelter such as a table, try to protect your head with items such as cushions. During an earthquake, fire sources, such as a stove or gas stove, should be turned off immediately to prevent fire. Usually we should develop the habit of shutting off the fire source during the earthquake.
1, package printing (package printing), with a variety of packaging materials as the main product printing. The packaging of goodsMachine or bandaging, filling, packaging, decoration and other operating processes. Packaging is the continuation of the production process of commodities in the circulation process, and it is an indispensable condition for commodities to enter the circulation and consumption field.
2. Packaging engineering, focusing on packaging science, physics, chemistry, materials science, aesthetics, color and other multidisciplinary fields, aims to meet the multiple needs of product protection, convenient storage and transportation and promote sales through design, printing, testing, management and research and development. Packaging engineering involves inner and outer packaging, structure, buffer and transport packaging design, while taking into account quality inspection and printing technology, aiming to provide comprehensive and efficient packaging solutionsCase.
3, my original packaging project also includes a year of printing engineering related professional learning, this you can probably be wide.
Compared with the UHF electronic label wireless carton , the label antenna turns more and the cost is higher. Read the distance of wireless carton When transmitting data between the tag and the reader, the low-frequency tag must be located in the near field area radiated by the reader antenna. The reading distance of a low-frequency label is generally less than 8 cm. The electronic label data can be read only one to one.
High-frequency labels are cheaper than UHF labels, save energy, penetrate non-metal physical strength, the operating frequency is not subject to radio frequency regulation, and it is most suitable for objects with higher water content, such as fruits. Uhf has a wide range of action and fast data transmission speed, but wireless cardboard boxes They are more energy consuming and penetratingWeak, the operating area can not have too much interference, suitable for monitoring items shipped from the port to the warehouse.
High-frequency electronic tags are used in electronic tickets, residential property management, the second generation of electronic identity cards, building access control, container identification and other aspects. The application scenario of UHF RFID electronic tags is quite broad, which can be used in asset management, supply chain management, intelligent warehouse management, vehicle management and so on. The operating frequency of UHF electronic tags is generally 850MHz ~ 910MHz and 45GHz.
The difference between high-frequency labels and UHF labels is mainly reflected in cost, penetration, and workFrequency, recognition sensitivity, data transmission speed, energy consumption and usage scenarios. High frequency labels have low cost, strong penetration and are suitable for water-containing objects, such as fruit.
Low frequency (from 125 KHZ to 134 KHZ) The frequency is mainly operated by inductive coupling, that is, there is a transformer coupling between the reader coil and the RFID tag coil. The voltage induced in the antenna by the reader alternating field is rectified and can be used as a supply voltage. The magnetic field region is well defined, but the field strength drops too fast.
