A capillary absorption spectrometer and process are described that provide highly sensitive and accurate stable absorption measurements of analytes in a sample gas that may include isotopologues of carbon and oxygen obtained from gas and biological samples. It further provides isotopic images of microbial communities that allow tracking of nutrients at the single cell level. It further targets naturally occurring variations in carbon and oxygen isotopes that avoids need for expensive isotopically labeled mixtures which allows study of samples taken from the field without modification. The method also permits sampling in vivo permitting real-time ambient studies of microbial communities.

The invention belongs to the technology of deep rock mass construction characteristic research in the field of high-level waste geological disposal research and the filed of engineering geological research, and particularly relates to a drill core direction recovery method. The method comprises the following steps: 1, drawing core base lines; 2, recording core structural faces; 3, measuring and explaining a borehole TV to obtain a borehole wall distribution diagram; 4, calibrating a core, determining reference faces and determining inclination of the reference faces; 5, determining the direction of the base lines, wherein an inclination value Zi of the reference faces is acquired according to a borehole TV measuring result, and then the direction of the base lines can be obtained according to the following equation and the relative positions of the reference faces and the base lines; 6, determining the inclination of the core structural faces, wherein the inclined values of the structural faces within the ranges of the base lines are determined according to the following equation and the relative positions of the structural faces within the ranges of the base lines. According to the technical scheme, the drill core direction recovery method can achieve system recovery of deep drill core structural face occurrence and further provide technical support for deep geological environment research.

The invention discloses a root box experiment device for plant root environment research. The device comprises a front baffle, a rear baffle, a U-shaped root separating plate, a nylon net, a soil water collecting pipe, a water-holding base, a fastening screw, an air vent and a water inlet, wherein the nylon net is attached to the surface of the U-shaped root separating plate; the U-shaped root separating plate and the nylon net are located between the front baffle and the rear baffle and are fixed by the fastening screw; a soil water collecting hole is formed at a lateral edge of the U-shaped root separating plate; the water-holding base is located at the bottom. According to the invention, each separating plate and the water-holding base of the root box experiment device both are detachable and reusable, so that the technical problem of collecting the soil sample and soil water sample in the plant root environment research can be solved; a collecting method for millimeter-scale root tiny-region soil and soil water in different regions can be further simplified and accurate; the research on differential characteristics on different positions of the root system of the crop is benefited; the further accurate research on the root soil interface behavior is benefited.

The invention discloses a compound microbial active filling material for removing sulphur-containing repugnant substances, as well as preparation and application of the compound microbial active filling material. Ochrobactrum anthropi SL1 and aquamicrobium defluvii SU1 related in the invention are isolated bacteria obtained in a reactor for processing repugnant substances, such as H2S, in a water pollution control laboratory of the ecological environment research centre of the Chinese academy of sciences. The bacterial strains are preserved in the general microbial centre of the Chinese general microbial strain preservation and management committee. The preservation numbers are CGMCC No.7400 and CGMCC No.7399 respectively. The compound microbial active filling material disclosed by the invention has the advantages of being large in specific area, high in porosity, good in air permeability, low in resistance, high in bacterial cell loading capacity and less prone to run away; and because of being loaded with ochrobactrum anthropi SL1 and aquamicrobium defluvii SU1, the compound microbial active filling material is difficult to decay and deform in a bioreactor for purifying waste gas, and therefore, the compound microbial active filling material can be used for a long time and is applied to complex processing conditions.
