Abstract: The application provides a high-purity thermostable crystal form of a substituted 3-isoxazolidinone compound, a preparation method therefor and an application thereof. The High-purity thermostable crystal form is prepared by a particular method of the present technology and is determined by single-crystal X-ray diffraction as an orthorhombic crystal, featuring a space group of P212121 and lattice parameters of a=9.2301(2) ?, b=11.0751(3) ?, c=12.7554(3) A, ?=90°, ?=90°, and ?=90°. The orthorhombic crystal can be conveniently applied in preparation of agrochemical formulations, such as a suspension concentrate and a water dispersible granule, and the new formulations prepared have a better herbicidal activity and crop safety.

Abstract: A cigarette core material capable of being ignited and heated at low temperature for smoking includes 50-95% of slice shreds and 5-50% of cut tobacco by weight percentage. The slice shreds include 40-55% of tobacco film bases, 15-25% of tobacco refined extracts, 0-5% of flavors and fragrances, and 15-30% of smoke additives by weight percentage. The cigarette core material is prepared by mixing the slice shreds with the cut tobacco in a reasonable ratio. The cigarette core material provided by the present invention is able to be heated at low temperature for smoking, and be directly ignited for smoking while the smoking set is out of power, both of which have high-quality sensory experience and can maximize the applicability of cigarette cores. The present invention is a co-product of traditional tobacco and new tobacco. It is also a new product of new market segmentation in the international market.

Abstract: An integrated ocean bottom towed four-component array for seismic data acquisition consists of a four-channel electronic section for seismic data collection, a gimbaled three-component geophone and a hydrophone in a housing. The array connects with a submarine cable through a cable joint in order to acquire four components of data consisting of seismic P wave, shear wave and hydrophone in total. Through cable data transmission and processing in a central station, ocean bottom oil and gas structure information can be obtained. Because of the high SNR acquisition in the ocean bottom seismic data acquisition of the present invention, and the waterproof cable interconnections between each of the sections of the present apparatus, data acquisition of high quality can be gained to realize highly efficient and easy ocean bottom towing operations.
