| 1 | Preconcentration and Separation of Trace Copper in Water Samples with Nanometer-Size TiO_2 Colloid and Determination by FAAS显示文摘A new absorbent of nanometer-size TiO2 colloid for Cu(Ⅱ) was studied in this work. The adsorption rate could reach above 99% when the pH values were at the range of 5-6. The adsorption balance time, adsorption capacities, and the eluent were investigated. A novel method of trace Cu(Ⅱ) preconcentration and separation with nanometer-size titanium dioxide colloid and determination by flame atomic absorption spectrometry (FAAS) was advanced. The detection limit (3σ) of the method was 1.15 μg· L^(-1) , and the relative standard deviation (R.S.D) was 1.53% (n=6). Environmental sample experiments were also conducted to test the feasibility of the method, and it came out that the recovery rates were between 95.9% and 97.8%. | QIAN Shahua LIN Han LI Xueqin XIAO Mei DENG Hongbing XIANG Luojing | 2007 | Wuhan University Journal of Natural Sciences2007，12，2： | 3 |
| 2 | One Year On-orbit Operation of Queqiao Lunar Relay Communications Satellite显示文摘Queqiao relay communications satellite was developed to provide relay communications services for the Iander and the rover on the far side of the moon.From entering into its halo mission orbit around the Earth-moon libration point 2 on June I4,2018,it has operated on orbit more than fifteen months.It worked very well and provided reliable,continuous relay communications services for the lander and the rover to accomplish the goals of Change 4 lunar far side soft landing and patrol exploration mission.The on-orbit operation status of Queqiao relay communications satellite is summarized in this paper. | ZHANG Lihua XIONG Liang SUN Ji CHEN Luojing | 2019 | Aerospace China2019，20，3： | 2 |

| 20 | Abnormal meiosis in fertile and sterile triploid cyprinid fish显示文摘Meiosis is the key process for producing mature gametes. A natural fertile triploid Carassius auratus population(3nDTCC) and an artificially derived sterile triploid crucian carp(3nCC) have been previously observed, providing suitable model organisms for investigating meiosis characteristics in triploid fish. In the present study, the microstructures and ultrastructures of spermatogenesis were studied in these fishes. Td T-mediated d UTP nick end labeling detection was performed to investigate the apoptosis of spermatocytes. Fluorescence in situ hybridization was employed to trace chromatin pairing. In addition, the m RNA expressions of cell cycle-related genes(i.e., cell division control 2 and cell cycle protein B) were determined by quantitative realtime polymerase chain reaction to illustrate the molecular mechanism of abnormal meiosis in the 3nCC. The results showed that the 3nCC undergoes an irregular prophase I, with the chromosomes distributed in a unipolar radial manner and exhibiting partial pairing, hindered metaphase I, and degenerated cells in the subsequent stages. Meanwhile, the 3nDTCC presented a relatively regular meiotic prophase I with complete conjugate chromosome pairs and chromosomes distributed along the karyotheca,which were presented as a ring structure by slicing. Only the spreads with 130–150 irregular chromosomes can be easily detected in the 3nDTCC, suggesting that it may undergo an abnormal metaphase I. This study provides new insights into the meiosis of fertile and sterile triploid cyprinid fish. | Chun Zhang Qi Li La Zhu Wangchao He Conghui Yang Hui Zhang Yu Sun Luojing Zhou Yuandong Sun Shurun Zhu Chang Wu Min Tao Yi Zhou Rurong Zhao Chenchen Tang Shaojun Liu | 2021 | Science China(Life Sciences)2021，64，11： | 1 |
