摘要:
A safety valve for battery has a valve body (1) and a valve core (2). The valve body (1) is fixed on a cover plate (4) of a battery and covers a discharging hole (9) in the cover plate (4) of the battery. The valve body (1) is formed with an exhaust opening (3) which is communicated with an internal space of the valve body (1). The valve core (2) is elastically held between a top cover (11) of the valve body (1) and the cover plate (4) of the battery. A plurality of columns (6) are arranged at intervals along a circumference of a gap between a side wall of the valve core (2) and an inner wall of the valve body (1). A cavity defined by every two adjacent columns (6), the side wall of the valve core (2) and the inner wall of the valve body (1) forms as a side exhaust slot (7) which is communicated with the exhaust opening (3) in the valve body (1).

The present invention provides a method for creating routes in access devices of the communication network by using access response messages. With the method provided by the present invention, services can be distinguished and forwarded based on destination IP sub-networks, so that different services can be distributed in access devices. In this way, on the premise that services are distinguished based on layer 3, the requirements for access devices are reduced and layer 2 networks on the user side are not required to carry out route protocols, which decreases administrators' maintenance work and is the important condition for the realization of plug&play and reduces the requirements for marginal routers.
摘要:
A method to control the distribution of the starch sugar's molecular weight by controlling of Ultra-low DE value during the reaction was invented. The method comprising blending starch with water to get starch slurry, and then mixing it with the 0.01%-0.03% of CaCl2 based on dried starch. The next step involves adjusting the pH of the starch slurry. A further step involves adding 0.03%-0.08% of heat-resisting α-amylases based on dried starch to the starch slurry described above. A further step involves controlling the production under optimal reaction conditions.
