A newly designed divertor Langmuir probe diagnostic system has been installed in a rare closed divertor of the HL-2A tokamak and steadily operated for the study of divertor physics involved edge-localized mode mitigation,detachment and redistribution of heat flux,*** sets of probe arrays including 274 probe tips were placed at two ports(approximately 180°separated toroidally),and the spatial and temporal resolutions of this measurement system could reach6 mm and 1μs,respectively.A novel design of the ceramic isolation ring can ensure reliable electrical insulation property between the graphite tip and the copper substrate plate where plasma impurities and the dust are deposited into the gaps for a long experimental ***,the condition monitoring and mode conversion between single and triple probe of the probe system could be conveniently implemented via a remote-control *** preliminary experimental result shows that the divertor Langmuir probe system is capable of measuring the high spatiotemporal parameters involved the plasma density,electron temperature,particle flux as well as heat flux during the ELMy H-mode discharges.

Background: As the population age structure gradually ages, more and more elderly people were found to have pulmonary nodules during physical examinations. Most elderly people had underlying diseases such as heart, lung, brain and blood vessels and cannot tolerate surgery. Computed tomography (CT)-guided percutaneous core needle biopsy (CNB) was the first choice for pathological diagnosis and subsequent targeted drugs, immune drugs or ablation treatment. CT-guided percutaneous CNB requires clinicians with rich CNB experience to ensure high CNB accuracy, but it was easy to cause complications such as pneumothorax and hemorrhage. Three-dimensional (3D) printing coplanar template (PCT) combined with CT-guided percutaneous pulmonary CNB biopsy has been used in clinical practice, but there was no prospective, randomized controlled study. Methods: Elderly patients with lung nodules admitted to the Department of Oncology of our hospital from January 2019 to January 2023 were selected. A total of 225 elderly patients were screened, and 30 patients were included after screening. They were randomly divided into experimental group (Group A: 30 cases) and control group (Group B: 30 cases). Group A was given 3D-PCT combined with CT-guided percutaneous pulmonary CNB biopsy, Group B underwent CT-guided percutaneous pulmonary CNB. The primary outcome measure of this study was the accuracy of diagnostic CNB, and the secondary outcome measures were CNB time, number of CNB needles, number of pathological tissues and complications. Results: The diagnostic accuracy of group A and group B was 96.67% and 76.67%, respectively (P = 0.026). There were statistical differences between group A and group B in average CNB time (P = 0.001), number of CNB (1 vs more than 1, P = 0.029), and pathological tissue obtained by CNB (3 vs 1, P = 0.040). There was no statistical difference in the incidence of pneumothorax and hemorrhage between the two groups (P > 0.05). Conclusions: 3D-PCT combined with CT

By the separation of singularity, a special Fourier series solution of the boundary value problem for plane is obtained, which can satisfy all boundary conditions and converges rapidly. II is proved that the solution is equal to the result of separation of variables. As a result, the non-linear characteristic equations resulting from the method of separation of variables are transformed into polynomial equations that can provide a foundation for approximate computation and asymptotic analysis.

探究影响棉花组培苗移栽成活率的主要因素,从而解决其直接移栽不易成活的技术难题,为棉花组培苗提供稳定高效的移栽途径。以棉花组培苗为供试材料,在不同环境、基质和根系状态的条件下探讨组培苗的成活率、根系和茎叶生长的研究。棉花组培苗在培养容器中诱导露白至生根,然后移栽到珍珠岩和蛭石以体积比1:1混合的基质中,使用1/2MS营养液,恢复时保持适当湿度,可以使苗更健壮,成活率从50%提高到100%,是一种操作简单、成活率高的棉花组培苗移栽方法。研究建立高效稳定的棉花组培苗驯化方法,成本低廉,避免嫁接,结铃率更高,可用于棉花生物技术产业化发展中。

曾纪泽(1839—1890),字劼刚,湖南湘乡人,晚清名臣曾国藩之子,近代著名外交官,曾出使俄、英、法等国。曾国荃(1824—1890),字沅甫,号叔纯,曾国藩之弟,湘军首领,累官至两江总督。光绪十年(1884),中法战争扩大,此前被调离法国的曾纪泽仍为出使英国大臣,在伦敦通过英国交涉中法冲突。光绪十一年十月英国入侵缅甸,俘虏缅甸国王,任期已满的曾纪泽暂缓归国,奉命与英国交涉缅甸事件。现从重庆中国三峡博物馆藏曾纪泽手札中,选辑其归国前在伦敦致曾国荃手札六通。这些手札通信双方是叔侄关系,谈军国大事,隐讳较少,特别是其中涉及中法战和、中英缅甸交涉以及筹办海军事务等内容,具有一定史料价值。兹选编辑注,希望能为相关研究增加一些新史料。
