The invention relates to a parking garage, in particular to a telescopic foldable hidden garage. The telescopic foldable hidden garage comprises a pair of garage bodies capable of retracting and expanding and a hidden garage pedestal which is arranged underground and used for collecting folded and retracted garage bodies, wherein, the expanded garage bodies are semicircular, and the vertical wall surfaces and the top wall surfaces of the garage bodies are connected with each other at a right angle or an arc angle; and the top of the garage pedestal is parallel to the ground. The telescopic foldable hidden garage has low manufacturing cost, saves the land used, and can achieve the principle of fully utilizing the spare land. For example, open-parking spaces which allow for long-term parking are arranged at a certain place; after the hidden movable garage is arranged, the garage has the winterproof, rainproof and theftproof functions on automobiles and can hidden in the garage pedestal under the condition of no parking, thereby the garage does not affect traveling and stopping of other vehicles and does not affect the prior beautiful appearance on the circumference and occupy the land.

The invention discloses an integrated modification method for reducing pollutant emission of a circulating fluidized bed boiler. The modification method comprises the following steps: modifications on a screen type heating surface, a material return system, an air distribution system, a secondary air nozzle system, a slag cooling system and a desulfurizer adding system. Through the modifications, the concentration of SO2 and NOx in smoke is finally reduced to 30-70% of that before modifications, the fly ash concentration is reduced to 70-90% of that before modifications and the environmental protection characteristic of boiler operation can be remarkably improved without adding new equipment. The integrated modification method has the advantages of being small in investment cost, short in modification period and stable in boiler operation; at the time the integrated modification is performed, the problems existing in arrangement of the original heat surface, a funnel cap, a separator, a slag cooler and a lime stone transmission system of the boiler can be synchronously solved, and therefore the economy, stability and safety performance of boiler operation are comprehensively improved.

The invention provides a distributed synchronization serial compensator. The compensator comprises a compensation module, a control module and a communication module, wherein the compensation module comprises a coupling transformer, a single-phase full-bridge inverter, a DC energy storage capacitor, a reactor and a bypass switch; the control module comprises a control circuit and a power supply circuit; and the communication module comprises a wireless communication assembly and a GPS assembly. The distributed synchronization serial compensator can effectively adjust the trend of a power transmission line, reduce the loss of a power transmission network and improve the power supply reliability.

The invention relates to a portrait cinerary casket prepared on the basis of a 3D (Three-dimensional) printing technology and a machining process thereof. The portrait cinerary casket comprises a portrait (2) and a base (3); at least one cavity is formed in the portrait (2); the bottom edge of the portrait (2) is provided with a convex edge (4) in a circumferential direction; a recess (5) is formed in the top end of the base (3) in a circumferential direction; the convex edge (4) and the recess (5) are tightly matched with each other; the portrait (2) has physical characteristics of a person. The portrait cinerary casket provided by the invention has the advantages as follows: people live with human rights and die with dignity; appearances and sounds are both remained in the world; the dead does not take the land from the living and does not destroy the good native land; reform and innovation start from the portrait cinerary casket and civilized funeral and interment pass down from generation to generation; thousands of kilometer timbers are saved and thousands of buildings can be built with the saved timbers; human remains are preserved in an reformed and innovated manner, so that the portrait cinerary casket benefits the nation and the people for thousands of year.

The invention discloses a method for quickly and accurately detecting the purity of a hybrid rice seed, which comprises the following steps: according to seed purity requirements, calculating the quantity of samples; sampling in a quantity-equal manner and mixing extracted DNA (deoxyribonucleic acid), or respectively extracting DNA and then mixing in a quantity-equal manner; designing PCR (polymerase chain reaction) primers according to the base sequence of detected sites, and amplifying the detected sites; recovering and purifying the PCR amplification products; building a library by using the amplification products, and performing high-flux sequencing; and calculating the seed purity according to the sequence proportion of the detected sites. The invention has the obvious characteristic that the requirements for detection speed and accuracy in the purity detection of a commodity hybrid seed are well satisfied.

The invention relates to an energy-saving single-phase embedded substation, wherein a single-phase transformer (1) and a low-voltage power distribution box (2) are assembled into a single-phase plug-in and embedded in a vertical wall of a building; Transformer (1) consists of load switch (F), backup protection fuse (FA1, FB1), plug-in fuse (FA2, FB2), tap changer (N1), primary coil (b1, b2), secondary coil ( N2, N3), incoming terminals (a, b) and outgoing terminals (a1, a2, X); low-voltage distribution box (2) consists of ammeter (A), voltmeter (V), main switch (QF), It consists of metering meter (KWh), each user shunt switch (K1~K10) and thyristor non-contact dynamic capacitance compensator (Q).

Domestic sewage treating underflow ecological bed method and apparatus is disclosed. Sewage is first treated in an anaerobic tank to eliminate BOD5, COD and SS; then treated in a biological carbon filter to provide carbon source for lowering nitrogen content, and treated in novel underflow ecological bed to eliminate nitride, phosphide, BOD5, COD, SS; and other pollutant; and finally gathered in a recovering pond for reuse or draining. The present invention solves the problems of no-power oxygen supply, jamming prevention, self purification, etc. of underflow ecological bed below thick soil layer, and the sewage treating system has simple operation, unmanned management, continuous running and high purifying effect.

The invention belongs to the field of food or healthcare products and aims at providing a brand new tall gastrodia tuber culture method, tall gastrodia tuber liquor and a tall gastrodia tuber culture method by using small-caliber containers. The tall gastrodia tuber culture method comprises the following steps of: 1) preparing culture medium; and 2) culturing tall gastrodia tubers. The key points are focused on the selection of tall gastrodia tuber culture medium and the control of culture conditions. The culture medium comprises potato culture medium, tree sawdust and halimasch. The preparation method of the culture medium comprises the following steps of: adding the tree sawdust into culture containers and adding the potato culture medium to submerge the tree sawdust; conducting disinfection; and inoculating and culturing the halimasch. By adopting the tall gastrodia tuber culture method, the period from the seeding to the harvesting of the tall gastrodia tubers is approximate 4-6 months; and the tall gastrodia tuber culture method has the advantages that the culture period is short, the survival rate is high, the diameter of the tall gastrodia tubers can reach 6-8cm and the like. The minimum diameter of the tall gastrodia tubers in the containers which contain the tall gastrodia tuber liquor is larger than the diameter of the mouths of the containers, the tall gastrodia tubers in the containers are intact and cannot be integrally taken out from the mouths of the containers, the containers are novel and interesting and can attract the curiosity of the public and a new product is provided for the public.
