Title: Low polarity resin, and preparation method therefor and use thereof
Inventor: SU MINSHE
IPC: C08G59/02
Filed: 2017-11-14
Abstract: The present invention provides a low polarity resin, and a preparation method therefor and the use thereof. The low polarity resin has a structure as shown in formula I and is based on a phenolic compound or resin, and prepared by a three-step reaction of allyl etherification, rearrangement and alkyl etherification. The resin does not contain polar hydroxyl groups in the molecular formula thereof, has a stable molecular structure, low polarity, and high reactivity, and does not generate polar hydroxyl groups during application and processing, thereby avoiding the influence of secondary hydroxyl groups on the performance of products thereof. While the resin improves the dielectric performance, same still has crosslinkable reactive groups which lead to no significant change in high temperature resistance after curing, can be used in one of the components of matrix resins in the resin composite material, and can be co-crosslinked and cured with other thermosetting resins, which significantly reduces the dielectric constant and dielectric loss of the resin. The use of the resin in the preparation of a metal foil clad laminate facilitates reducing the dielectric constant and dielectric loss of the metal foil clad laminate, and results in higher resistance to high temperature, such that the metal foil clad laminate has good comprehensive properties.

Abstract: Disclosed are a method and device for determining a multi-antenna transmission mode. The method comprises: a terminal device measuring a channel busy rate (CBR); and the terminal device determining, according to a magnitude relationship between the CBR and a CBR threshold, a multi-antenna transmission mode for transmitting data. Therefore, when selecting a transmission mode, a terminal device measures a CBR and compares the measured CBR with a CBR threshold, so as to determine, according to a comparison result, a multi-antenna transmission mode for transmitting data. In this way, when a system resource occupancy rate is low, the terminal device can use a transmission mode, i.e. transmission diversity, to transmit data to other terminal devices, thereby improving the reliability of data transmission; moreover, when the system resource occupancy rate is relatively high, the terminal device is prohibited from using the transmission mode, i.e. transmission diversity, thereby reducing the influence on the data transmission of an R14 terminal device.

Abstract: A three dimensional space identifying and positioning method for a water inrush channel (2) in an underground rock mass, comprising the following steps: step 1, determining the location of a water inrush water source, and drilling a drill hole in an underground space (4) in the direction from the underground rock mass to the water inrush water source (9); step 2, placing a plurality of micro signal-emitting balls (7) into the water inrush water source by means of the drill hole (9), and providing a positioning signal transmitter (15) in the micro signal-emitting balls (7); step 3, arranging a signal receiving probe (10) at the position of the water inrush water source by means of the drill hole (9), the signal receiving probe (10) being connected by a signal to a signal analyzer (6), and the signal analyzer (6) receiving spatial location information of each micro signal-emitting ball (7) by means of the signal receiving probe (10); and step 4, determining the spatial location distribution of the water inrush channel (2) in the underground rock mass according to the spatial locations of all micro signal-emitting balls (7), and determining a primary water inrush channel and a secondary water inrush channel in the underground rock mass according to the degree of aggregation of the micro signal-emitting balls (7). By employing the described method, the water inrush channel (2) in the underground rock mass may be spatially positioned.

Abstract: 一种降低压缩机预热噪音的控制方法，压缩机预热时，对压缩机绕组U、V、W分时通电，在每个通电周期内，控制两相绕组通电，且每相绕组的通电电流为波动电流，每个通电周期划分为多个子时段，控制同一子时段内的通电电流大小相等，控制相邻子时段的通电电流大小不等，在压缩机预热之前，所述控制方法还包括：获取室外环境温度Ta，根据室外环境温度Ta确定每个预热周期的预热时间。
