Insight-HXMT was designed to have a broad energy coverage in X-rays, from 1-250 keV, with excellent timing and adequate energy resolution at soft X-rays, and the largest effective area at hard X-rays. This allows, in particular, to observe bright sources like X-ray binaries (XRBs) in their bright/outburst states with high cadence and high statistics at hard and soft X-rays at once. It was then expected that the Insight-HXMT mission will bring us new insights regarding the characteristics of several source classes. Examples include characterizing High-Mass X-ray Binaries (HMXBs) and the outburst evolution of Low-Mass X-ray Binaries (LMXBs). For instance, in HMXB systems, the region around their Alfven radius that is responsible to determine whether accretion or propeller occurs, or the region around the NS magnetic pole where the intense X-rays are supposed to be produced are specially appealing targets of study. For the LMXBs, the evolution the outburst and the properties of the compact objects themselves are obvious priority targets for Insight-HXMT. Due to the broad coverage in energy, Insight-HXMT is specially well suited to study the influence of thermonuclear (type-I) X-ray bursts upon the surrounding environment.   ANALYSIS ON ENRICHMENT OF AQUATIC PLANTS RESPONSE TO DIFFERENT HEAVY METAL IONS IN POLLUTED WATER TAKING DUCKWEED AS AN EXAMPLE 期刊论文  OAI收割 APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2019, 卷号: 17, 期号: 2, 页码: 3469-3482 作者:  Zhao, Y.;  Feng, G.;  Yang, Z.;  Ouyang, Z.   |  收藏  |  浏览/下载：103/0  |  提交时间：2019/05/21 duckweed  heavy metal ions  enrichment  chlorophyll content  determine   In-orbit Demonstration of X-Ray Pulsar Navigation with the Insight-HXMT Satellite 期刊论文  OAI收割 The Astrophysical Journal Supplement Series, 2019, 卷号: 244, 页码: 1 作者:  HXMT   |  收藏  |  浏览/下载：15/0  |  提交时间：2022/02/08 pulsars: general  techniques: miscellaneous  Astrophysics -  Instrumentation and Methods for Astrophysics  Abstract: In this work, we report the in-orbit demonstration of X-ray pulsar navigation with Insight-Hard X-ray Modulation Telescope (Insight-HXMT) Satellite, which was launched on 2017 June 15. The new pulsar navigation method Significance Enhancement of Pulse-profile with Orbit-dynamics is adopted to determine the orbit with observations of only one pulsar. In this test, the Crab pulsar is chosen and observed by Insight-HXMT from 2017 August 31 to September 5. Using the five-day long observation data, the orbit of Insight-HXMT is determined successfully with the three telescopes onboard: High Energy X-ray Telescope, Medium Energy X-ray Telescope, and Low Energy X-ray Telescope, respectively. By combining all the data, the position and velocity of the Insight-HXMT are pinpointed to within 10 km (3ҩ and 10 m s-1 (3ҩ, respectively.   Green Quantification Strategy Combined with Chemometric Analysis for Triglycerides in Seeds Used in Traditional Chinese Medicine 期刊论文  OAI收割 PLANTA MEDICA, 2018, 卷号: 84, 期号: 6-7, 页码: 457-464 作者:  Hou, Jin-Jun;  Guo, Ji-ling;  Cao, Chun-Mei;  Yao, Shuai;  Long, Hua-li   |  收藏  |  浏览/下载：46/0  |  提交时间：2019/01/08 triglycerides  single standard to determine multicomponents  Coix lacryma-jobi var. ma-yuen  Poaceae  triolein  core-shell  chemometrics   A single, multi-faceted, enhanced strategy to quantify the chromatographically diverse constituents in the roots of Euphorbia kansui 期刊论文  OAI收割 JOURNAL OF PHARMACEUTICAL AND BIOMEDICAL ANALYSIS, 2014, 卷号: 88, 页码: 321-330 作者:  Hou, Jin-Jun;  Wu, Wan-Ying;  Liang, Jian;  Yang, Zhou;  Long, Hua-Li   |  收藏  |  浏览/下载：25/0  |  提交时间：2019/01/08 Single standard to determine multi-components (SSDMC)  Euphorbia kansui  Exogenous reference standard  Ingenane diterpenoids  Jatrophane diterpenoids   Strategies for elaboration of comprehensive quality standard system on traditional Chinese medicine 期刊论文  OAI收割 China Journal of Chinese Materia Medica, 2014, 卷号: 39, 期号: 3, 页码: 351-356 作者:  Wu Wanying;  Guo De'an   |  收藏  |  浏览/下载：23/0  |  提交时间：2019/01/08 comprehensive quality standard system for traditional Chinese medicine  quality control  reference extract  reference fingerprint  single standard to determine multi-components (SSDMC)   The application of digital signal processing (DSP) for the real time solving of artillery fire control exterior trajectory (EI CONFERENCE) 会议论文  OAI收割 2012 IEEE 3rd International Conference on Software Engineering and Service Science, ICSESS 2012, June 22, 2012 - June 24, 2012, Beijing, China 作者:  Li D. 收藏  |  浏览/下载：141/0  |  提交时间：2013/03/25 Method of gain firing data by calculate the group of differential equation has the advantages of high repeatability and high accuracy  But much of the CPU time is occupied by the task of re-iteration in computational processing. Therefore  it is not the real time processing. This paper introduces a method to quickly determine angle of firing by iteration method  which realizes Runge-Kutta method for the equations of exterior ballistic according to the model of mass center motion of projectile. Moreover  it also provides the flow of real-time integral solution and be proved by the simulation of MATLAB. Its accuracy satisfies the requirements. This work can be as reference for the design of opt-electrical fire control system and the demonstration work. 2012 IEEE.   A sub-pixel extraction method for the center of the circular structure from spot array calibration target (EI CONFERENCE) 会议论文  OAI收割 2012 3rd International Conference on Information Technology for Manufacturing Systems, ITMS 2012, September 8, 2012 - September 9, 2012, Qingdao, China 作者:  Liu Y.;  Zhang T.;  Yang H.;  Gao X.;  Liu Y. 收藏  |  浏览/下载：75/0  |  提交时间：2013/03/25 The imaging measurement system must be calibrated before application. In calibration procedure  sub-pixel center extraction is the crucial step for the final accuracy. In this paper  a new sub-pixel extraction method is proposed. Edge detection at pixel level is obtained using LOG operator  then sub-pixel edge detection is realized using the Facet model. Finally  the least squares ellipse fitting is operated on the sub-pixel edge to determine the sub-pixel center. Experiment on a series of simulated images indicates that this algorithm is able to realize the center location accuracy of 0.01-0.02 pixel  and meets the requirement of sub-pixel level.
