China's high-end scientific research equipment is 100% dependent on imports. In 2010, the import and export deficit hit a new high, which shows that China is still mainly dependent on imports in high-end high and low temperature box manufacturers' products. China's high and low temperature box manufacturers have a large demand, and then the technical level of domestic instrument equipment companies is still behind that of foreign countries. Therefore, some of the "opportunities" have been lost. To seize the opportunities, seize the market, and improve the technical level is the key. High-tech equipment industry has become the mainstream of development. In the past two decades in the world, high-tech technologies such as microelectronics technology, computer technology, precision machinery technology, high sealing technology, special processing technology, integration technology, thin film technology, network technology, nanotechnology, laser technology, superconducting technology, and biotechnology Rapid development. This background and situation have constantly raised higher, newer and more requirements for high and low temperature chamber manufacturers, such as faster speed, higher sensitivity, better stability, less sample volume, detection of micro-loss or even non-destructive , Remote sensing remote control distance is farther, more convenient to use, lower cost, no pollution, etc. At the same time, it also provides a strong impetus for the development of high and low temperature box manufacturers' technology industry, and has become a material and knowledge for the further development of high and low temperature box manufacturers And technical foundation. Convenient folding for long battery life. fold Jiangsu Anywhere Mobility LTD. , https://www.annelectricscooter.com
