摘要： A particle sampling device includes: a chamber having a main inlet, a main outlet, a bypass inlet and a bypass outlet, a bypass pipeline between the bypass inlet and the bypass outlet being located outside of the chamber; a gas suction pump and a gas pressure regulating valve provided on the bypass pipeline; and a gas pressure sensor and a temperature and humidity sensor for detecting parameters of aerosol flow inside the chamber. An opening degree of the gas pressure regulating valve and a rotation speed of the gas suction pump are under a feedback control of a scattering signal frequency of individual particles recorded by the aerosol mass spectrometer. A linear relationship between ln(τ) and ln(Stkm)1/2 is derived and verified experimentally, where t represents a flight time of particles, and Stkm represents a modified Stokes number of the corresponding particles.

摘要： A method for managing a consortium chain data structure network, a management node, and a non-transitory computer-readable recording medium are provided. The consortium chain data structure network includes a first network that maintains a first chain data structure for recording management data, and a second network that maintains a second chain data structure for recording user data. A management node for management consensus of the consortium chain data structure network only accesses the first network. In the method, the management node receives a management request message sent by a requesting node, verifies the management request message, and processes the management request message in response to successful verification on the management request message. A data block in the first chain data structure is generated based on a result of the processing.

摘要： A device at a transmitting side includes a channel detection unit configured to detect whether a transmitting-end channel in an unlicensed frequency band is idle; and a coordination unit configured to enable, if the transmitting-end channel is idle, the transmitting side to broadcast an inter-operator coordination signal before transmitting a data stream, so as to realize information interaction between apparatuses of different operators, wherein the inter-operator coordination signal implements, by means of presence/absence of energy in a specified frequency band, an energy pattern signal on a time-frequency domain plane for the information interaction between the apparatuses of different operators. By enabling inter-operator information interaction in an unlicensed frequency band by means of an energy pattern signal, the embodiments of the present disclosure eliminate difficulties of reception and demodulation for signal detection between apparatuses of different operators, thus effectively realizing coordination between the apparatuses of different operators, and improving system performance.

摘要： An environment protected starch container device with high hardness and a function of easy separation from a mold includes a starch container mainly made of starch material for holding solid or liquid foods or other objects; and a silicon layer adhered to a surface of the starch container. The function of the silicon layer is to cause the starch container to be waterproof; furthermore the silicon layer and the starch container are capably of decomposition naturally without polluting the environment; therefore the container is capable of holding water therein and is reusable for many times. The starch material comprises 50 wt %˜90 wt % (weight percentage) starch; 5 wt %˜25 wt % fiber enhancer for enhancing a structure of the starch material; and 3 wt %˜30 wt % CaCO3 for hardening the structure of the starch material. The starch material may further comprise 0.02 wt %˜5 wt % foaming material. The starch material is mixed with stearic acid; and the silicon layer further comprises of quartz.
