The invention provides a refrigerant oil composition and application thereof. The refrigerant oil composition comprises, on the basis of the weight of base oil, (1) 15 to 40 wt% of alkyl benzene synthetic lubricant base oil, (2) 15 to 40 wt% of oil-soluble polyether base oil, i.e., OSP base oil, (3) 20 to 70 wt% of high-pressure hydrogenation cycloalkyl mineral lubricant base oil, and (4) an additive, wherein the high-pressure hydrogenation cycloalkyl mineral lubricant base oil is prepared by using a high-pressure tandem all-hydrogen process consisting of hydrodemetallization, hydrotreatment, hydrodewaxing and hydrofinishing. The refrigerant oil provided by the invention has good intersolubility with hydrochlorofluorocarbons (HCFCs, such as R22), a low flocculation point and thermo-chemical stability; the refrigerant oil is especially applicable as refrigerant oil with HCFCs as refrigerants and also applicable as refrigerant oil with chlorofluorocarbons as refrigerants; and the refrigerant oil can prolong an oil change period and improve energy conservation performance, and has excellent abrasion resistance.

The invention discloses a biodiesel lower-temperature fluidity improver, which is an ethene-vinyl acetate-maleic anhydride-styrene quadripolymer and has the chemical structural formula (I), wherein k, L, m and n are respectively an integer ranging from 5 to 50. The invention also discloses a preparation method of the biodiesel lower-temperature fluidity improver. The biodiesel lower-temperature fluidity improver has excellent stabilization and dispersion function for microcrystalline and can effectively lower the condensation point and the cold filtering point of biodiesel, thereby improving the sensitivity of the biodiesel from different sources.

The invention provides a taste-masked oral membrane containing nano lignin and a preparation method thereof. The taste-masked oral membrane contains nano cellulose, nano lignin, xylitol, polydopamine and pharmaceutical ingredients; the above materials are mixed and then subjected to strong mechanical stirring and strong ultrasonic treatment to be uniformly mixed, and the film-forming agent is obtained after bubble removal and drying. The nanocellulose is a film-forming main body material and a disintegration component; the nano lignin and the polydopamine have drug loading capacity; meanwhile, the nano lignin and the polydopamine both have a bonding function in the membrane structure, and instant dissolution or slow release of the membrane agent can be realized by regulating and controlling the dosage of the nano lignin and the polydopamine. Xylitol is used as a flavoring agent and has the function of preventing decayed teeth; the dissolving heat absorption makes the mouth cool and refreshing. The membrane agent is good in biodegradability, and the preparation method is simple and easy to implement. The membrane agent solves the problems of poor compliance of patients to bitter drugs and the like, and realizes high value-added application of the nano lignin derived from wood fibers in the field of oral membrane agents.

The invention discloses a method and a device for program service recording and broadcasting of a mobile terminal. The method comprises the following steps of: when the broadcast of a program service is suspended or stopped, starting the recording of the program service; storing the recorded contents into a plurality of segments of storage spaces which are spare and have the same size and numbers in order, wherein the numbers correspond to the sequence of the recorded contents in a plurality of segments of the storage spaces; and when recorded contents are stored in the segment of the storage space with the last number, clearing the storage space with the first number, and resetting the numbers of the storage spaces according to the sequence of the recorded contents. By segmenting and numbering the storage spaces and deleting the contents recorded at earlier time when the recorded contents are excessive, the method and the device achieve cyclic recording under the condition of storing the recorded contents as many as possible, so that the effect of user experience is improved.

In the present invention, the following are provided: a generation means for generating a vibration, or a vibration signal, of a first band that contains a vibration component that is perceived as sound by the auditory system of an organism, and of a second band, from among bands that exceed the first band, that contains a vibration component that elicits an effect for reducing brain activity; and a vibration presentation means for reducing the brain activity of the organism by imparting to the organism the vibration having the second band and the vibration of the first band.

The invention relates to the technical field of combined sound equipment, and discloses a sound equipment folding and unfolding device for solving the problem that the use effect is influenced by dustpollution, the sound equipment folding and unfolding device comprises a shell, and the top of the shell is movably connected with a cover plate; through the combined action of the toothed bar and themovable assembly, the placement condition of the combined sound equipment is controlled according to the use requirements, and the opening and closing operation is triggered by utilizing the operation condition of the combined sound equipment, so that the cover plate does not shield the sound equipment any more, the sound equipment is convenient to move out, the sound equipment is retracted and released under the non-use condition, and the dust pollution is reduced; and the sound equipment can be normally used, is protected, is prevented from being damaged by external impact, and is automatically lifted to be directly exposed to the outside, and compared with a common fixed placement mode, the transmission effect of the sound effect of the sound equipment is improved, the feeling effect is improved, and the sound equipment is more suitable for the actual use condition.
