Abstract: A battery module includes a battery cell assembly and a fire extinguishing member. The battery cell assembly includes a plurality of battery cell frames and a plurality of battery cells. The plurality of the battery cell frames are arranged sequentially along a length direction of the battery module. At least one battery cell is provided in at least some of the battery cell frames. Each battery cell frame is provided with a fire extinguishing slot, and the fire extinguishing slots on the plurality of the battery cell frames are communicated to each other to form a fire extinguishing channel. The fire extinguishing member is arranged in the fire extinguishing channel. The fire extinguishing channel extends along the length direction of the battery module, and the fire extinguishing member extends along the length direction of the battery module in the fire extinguishing channel.

Abstract: Use of an indica rice OsRNR10 gene in enhancing rice root system development, and improving nitrogen use efficiency and yield, where sequences of the indica rice OsRNR10 gene are shown in SEQ ID NOs: 1 and 2. 82 IRAT261-carrying single segment substitution lines under the background of Huajingxian 74 are utilized to carry out a quantitative trait locus (QTL) analysis. A nitrogen-response root system development regulatory factor OsRNR10 is further finely mapped. The indica rice haplotype OsRNR10 reduces the expression level, and enables indica rice to have a better root system architecture and a higher nitrate nitrogen uptake rate. By introducing an excellent allelic variation of OsRNR10 in the indica rice into japonica rice, the root system development of the japonica rice can be enhanced, and the nitrogen use efficiency and yield of the japonica rice can be improved.

Abstract: The present invention provides a detecting apparatus, including a storage chamber containing a treating fluid; wherein, the detecting apparatus is internally provided with a sharp-pointed portion; the storage chamber may make a movement relative to the sharp-pointed portion; the storage chamber will be pierced by the sharp-pointed portion during the moving process, such that the treating fluid in the storage chamber is released. The detecting apparatus further includes a collecting chamber; the released treating fluid may flow into the collecting chamber; the collecting chamber is disposed inside a first shell and used to contain a sample; an opening is disposed at an upper position of the first shell; the collecting chamber is internally provided with a testing element for detecting an analyte; the testing element is disposed on a carrier, and the carrier has a specific matching form with the collecting chamber.

Abstract: In one embodiment, an optical switch includes: a first dual-fiber collimator comprising a first pair of optical fibers; a second fiber collimator comprising an output optical fiber; a switching prism movable between a first position and a second position, and a first mirror facing the first collimator. In the first position, the switching prism directs light from an input fiber of the first collimator into the output fiber of the second collimator. In the second position, the switching prism is positioned out of an optical path of light emitted from the input fiber of the first collimator. The first mirror is aligned to reflect light from the input fiber of the first collimator into an output fiber of the first collimator when the switching prism is in the second position. The second collimator may be a dual-fiber collimator, and a second mirror may be placed facing the second collimator.
