    摘要： The present invention relates to an aqueous phase process for purifying long-chain dicarboxylic acids from a liquid containing a long-chain dicarboxylic acid/or a salt thereof. The invention overcomes the disadvantages of low purity and high chroma of the product obtained by using the aqueous phase process of the prior art. Through the step of crystallizing the monosalt of long-chain dicarboxylic acid, the present process reduces effectively the content of such impurities as proteins and coloring materials in the product and obtains the long-chain dicarboxylic acid product having a total acid content of greater than 99 wt % and exhibiting a white appearance.

    摘要： Method, system, and programs for reducing network latency in a network. A first connection is established between a relay and a host in the network. The relay receives non-confidential information from the host over the first connection. A second connection is then established between the relay and a node in the network. The relay then communicates with the node, over the second connection, non-confidential information on behalf of the host based on the received non-confidential information from the host. The relay also forwards, over the first and second connections, confidential information between the node and the host.

    摘要： A method and device for locating voice transmission problems are provided. The method includes: configuring a data transmitting/receiving statistics module at each transmission stage of a media stream to perform statistics on data transmitting/receiving of the transmission stage; the data transmitting/receiving statistics module reporting data after statistics to a preset data analysis module; and the data analysis module locating the voice transmission problems after analyzing the data reported by the data transmitting/receiving statistics module. The device includes the data transmitting/receiving statistics module and the data analysis module. The method and device can automatically detect the voice transmission problems such as getting through in one-way, discontinuous, etc., and discover the voice transmission problems existing in the system in time, thereby quickly locating the transmission stage of the media stream at which the voice transmission problems appear, enhancing the location efficiency of the voice transmission problems, and shortening the fault location period.
