Abstract: Disclosed is a blockage-proof water diversion and drainage device for highway tunnel construction. The device may include an inlet cleaning component, a diversion component connected to a bottom of the inlet cleaning component, a debris collection component connected to an end of the diversion component close to the inlet cleaning component, and a pre-storage component connected to a bottom of the diversion component. An outlet end of the pre-storage component may be connected to the debris collection component. An openable baffle component and a screen plate may be provided inside a main pipe of the diversion component which can transfer filtered sludge and other debris to the debris collection component, keeping the main pipe clean, maintaining the drainage speed of accumulated water, and reducing the frequency of manual cleaning. Additionally, the device can scrape and clean a surface of the screen plate to prevent blocked, thus extending device maintenance time.

Abstract: A monitoring device for methane gas in a hot thaw lake pond in a tundra region is provided, comprising a top plate, an adjusting mechanism, and a monitoring mechanism. A bottom portion of the top plate is fixedly connected with a fixed column, and the fixed column is slidably mounted on the adjusting mechanism. The monitoring mechanism is connected to the adjusting mechanism, and the monitoring mechanism controls entry and exit of water to be detected and detect a methane gas in the water. The position of the mounting cylinder of the monitoring mechanism is adjusted by an electric push rod to facilitate the monitoring of methane concentration at different positions. In the mounting cylinder of the monitoring mechanism, a turntable with a filter membrane that is lifted and rotated is provided to facilitate controlling the direction of liquid movement while promoting the upward movement of the gas to detect methane concentration, and the liquid periodically to detect the methane concentration, which achieves the purpose of detecting the methane concentration by periodic liquid replacement. Additionally, the present disclosure also provides a debris removal mechanism that is capable of scraping weeds from the outside of the mounting cylinder.

Abstract: A seed development device for Psammochloa villosa using condensate water in desert areas includes: a cultivation box, a top surface of the cultivation box is connected to a cooler and condensate water collecting units through a support frame. Each condensate water collecting unit includes an outer frame, sleeve pipes, a middle frame, a cold air cavity, water collecting rods, a water collecting tank and a delivery pipe. The delivery pipe is connected to the cultivation box. When an outdoor temperature cannot complete condensation of water vapor, the cooler completes cooling of the cold air cavity and water collecting rods until condensate water collection is completed, water drops fall into the water collecting tank to complete water collection, which is used for water supplement of seed development of Psammochloa villosa, thus reducing the process of artificial water supplement and improving the development efficiency of seeds of Psammochloa villosa in desert areas.

Abstract: A preparation method of a molecularly imprinted polymer (MIP) for separation and concentration of 4-methylsterane compounds is provided. A template molecule, a functional monomer, a porogen, an initiator and a cross-linking agent are mixed and subjected to polymerization to prepare a polymer with the template molecule, which is then treated to remove the template molecule, so as to give the desired MIP. The template molecule is β-sitosterol or deoxycholic acid. The obtained molecularly imprinted polymer has multiple stable hole structures and binding sites inside, and has memory and recognition functions for the 4-methylsterane compounds, exhibiting excellent specific adsorption performance. The MIP can contribute to the accurate identification of correlation between depositional environment and maturity of crude oils or source rocks. A molecularly imprinted polymer prepared by such method, a chromatographic column and an application thereof are also provided.

Abstract: A method for separating diastereomers of pristane. A pristane sample is prepared, and then injected into a chromatographic instrument equipped with a chiral chromatographic column, where a stationary phase of the chiral chromatographic column has a preset pore size. The pristane diastereomers in the pristane sample are separated by the chiral chromatographic column, and the components produced by the separation of the pristane diastereomers sequentially enter a mass spectrometer for detection and analysis.
