The invention discloses semidry-process desulfurization ash putty for an interior wall. The putty for the interior wall comprises the following components (in percentage by mass): 25-35% of semidry-process desulfurization ash, 10-20% of steel slag, 30-45% of superfine slag powder, 10-25% of calcium-magnesium powder, 0-5% of water retaining agent and 0-5% of emulsion powder. According to the invention, people can know that the putty is prepared by taking waste steel slag generated by steel slag enterprises, mineral slag and desulfurization slag instead of heavy calcium carbon as raw materials, therefore, when a mixture obtained after putty powder is mixed with water is used for coating a wall, the water resistant performance of the wall can be good, and the growth of mildews growing under a humid survival condition is also inhibited; the prepared putty wall is mild in color, therefore, a favorable decoration effect can be achieved.

A gourd silk, belonging to national musical instruments, especially a musical instrument made of gourds and bamboo pipes played by the Dai, Wa, Blang and Achang nationalities in southwest my country. The top of the gourd silk main sound pipe of the present invention is fixedly connected with the gourd, the reed is installed in the gourd at the top of the main sound pipe, the sub-sound pipes are on both sides of the main sound pipe, the sound holes are opened in the front and back of the main sound pipe, and the plug is plugged on the left or The secondary sound pipe on the right is characterized in that its reed is made of copper sheet, and the number of sound holes is 10, 6 at the front and 4 at the back. Determine the length and inner diameter of the main sound pipe, the diameter of the sound hole, and the distance between the sound holes to produce gourd silk with different tones. The limitation of human experience is conducive to the inheritance, popularization and development of this traditional folk musical instrument, and the inheritance and development of excellent national culture.

The invention discloses a power device with a micropulse wave absorption function. The power device comprises a rectification and filter module, a first micropulse wave discharge module, at least one micropulse wave insulation module, at least one second filter module and a second micropulse wave discharge module. The rectification and filter module comprises a rectifier bridge and a first filter capacitor. The first micropulse wave discharge module is arranged at the output end of the rectifier bridge and used for discharging micropulse waves generated by the first filter capacitor. The micropulse wave insulation modules are sequentially arranged at the output end of the rectifier bridge and used for insulating out negative micropulse waves generated by a pin inductor of the first filter capacitor, and each second filter module comprises a second filter capacitor. The second micropulse wave discharge module is arranged at the output end of the power device and used for carrying out secondary discharging on residual micropulse waves passing through the at least one micropulse wave insulation module and micropulse waves generated by the second filter capacitors. According to the power device, micropulse waves with time intervals shorter than a nanosecond section and a microsecond section can be absorbed, the transient performance and EMC performance of a power source in a high-frequency circuit system are effectively improved.

The invention relates to series of Qinhu nuts, which is characterized in that hard maple is selected as raw material to make into block body of 'axe' shape, the upper top face of the block body is equipped with two open slots which is used to support strings, two voice holes on the upper portion of the block body are respectively communicated with the lower circular arc long through hole, the bottom of the block body is equipped with a long circular through hole with 'arch' opening which is connected with a resonating plate. The invention has advantages that the vibration and conduction are extremely good, impurity is filtered to make the voice purer, the shape and the structure are more suitable for the happening and vibrating of the panel musical instruments, the two voice holes loose the voice and soften tone quality, the long through hole can filter noise and the bottom is equipped with a semi-circle hole with opening connecting with the resonating plate, which is more favorable for the advantages and effects of the conduction and happening of the voice.

The invention relates to a low-power-consumption color changing wall unit comprising an infrared remote controller, an infrared receiving and decoding circuit, a peripheral interface controller (PIC) singlechip, a power generator, an liquid crystal display (LCD) screen drive circuit and a liquid crystal unit, wherein the infrared receiving and decoding circuit, the PIC singlechip, the power generator, the LCD screen drive circuit and the liquid crystal unit are collected in sequence; the infrared receiving and decoding circuit communicates with the infrared remote controller; the liquid crystal unit comprises anti-dazzle glass, a blue LCD screen and a brown LCD screen painted with black printing ink at the back, which are arranged in sequence so as to overlap into seven colors; the blue LCD screen and the brown LCD screen are multi-steady-state LCD screens; the infrared receiving and decoding circuit, the PIC singlechip, the power generator and the LCD screen drive circuit are arranged on a back plate; and the liquid crystal unit and the back plate are arranged from top to bottom, and are sealed by frames. Compared with the prior art, the low-power-consumption color changing wall unit provided by the invention has the beneficial effects of integrating multiple techniques, such as infrared remote control and multi-stead-state liquid crystal and the like into a whole, and havingthe advantages of energy conservation, environmental protection, beautiful decoration, as well as flexibility and convenience for operation and the like.

The invention relates to a photochromic heterocyclic substituted spiro-azine compound nanocomposite material, which comprises the following composition in weight percent: 2-20% of a photochromic heterocyclic substituted spiro-azine compound nanocomposite, PMMA resin powder 76~94%, light stabilizer: bis(2,2,6,6-tetramethyl-4-hydroxypiperidine) sebacate 0.01~1%, singlet oxygen quencher: N,N-di Nickel n-butyldithiocarbamate 0.01-1%, antioxidant: 2,2'-methylene bis(4-methyl-6-tert-butylphenol) 0.02-2%. The photochromic nano-composite material of the present invention has excellent photochromic properties, and under the irradiation of visible light or ultraviolet light, it has fast color development, high chroma, fast fading, good fatigue resistance, simple synthesis process, low price and high color rate. Relatively high, the fading rate is adjustable. And it can be well dissolved in various polymer media, and can be used to prepare photochromic PMMA sun lens materials for radiation protection.
