水体中的硝氮质量浓度不断升高,对水生态系统和人类健康存在潜在威胁。因此,解决水体中过量硝氮的问题刻不容缓。以Fe(NO_(3))_(3)·9H_(2)O、Co(NO_(3))_(2)·6H_(2)O、芦苇生物炭、NH_(3)·H_(2)O为原料,采用共沉淀法将钴铁层状双金属负载到芦苇生物炭上,制备了可用于吸附水体中过量硝氮的Co/Fe-LDH@BC。结果表明,Co/FeLDH@BC可有效吸附水体中的硝氮,其吸附量为88.52 mg/g;吸附动力学模型符合伪二级动力学模型,等温线符合Langmuir等温线模型,说明吸附反应为自发的、吸热的,主要涉及离子交换、配体交换、静电吸引、氢键四种反应机理;Co/Fe-LDH@BC在大多数共存阴离子的水体中对硝氮具有很强的亲和力,具有实际应用价值。

Gas-washing and water injection are two commonly used methods in generating certain moisture content in gas flow stream, but the control accuracy of these methods remains uncertain. The purpose of the study is to investigate the characteristic of water vapor generation of the two methods. The temperature and humidity recorder and FTIR gas analyzer have been adopted to monitor the moisture content in tests. It has been revealed that, in gas-washing process, the moisture content in gas stream is well below saturation, and long time is required before moisture content stabilized after water bath temperature or carrier gas flow rate changed. Water injection pump could directly control the amount of water injected into gas stream. However, the moisture content generated in this way is not stable but oscillates in cycles, whose frequency and magnitude are closely related to water injection amount.

Purpose:.Glaucoma is an eye disease that can lead to irreversible optic nerve damage and cause blindness. Optical coherence tomography.(OCT) allows an early diagnosis of glaucoma by the measurements of the retinal nerve fiber and optic disc parameters.A retrospective study was designed to analyze the effects of the measurement of the retinal nerve fiber layer(RNFL) thickness and the optic disc tomography by spectraldomain OCT on the early diagnosis of suspected glaucoma and primary open angle glaucoma(POAG).Methods:.This was a clinical case-control study. The RNFL thickness around the optic disc and optic disk tomographic parameters of the control(n=51, 98 eyes), suspected glaucoma(n=81,.146 eyes), and POAG groups(n=55, 106 eyes) were measured by OCT. The parameters included superior, inferior, nasal and temporal mean RNFL thickness,.disc area(DA), cup area(CA), rim area(RA), disc volume(DV),cup volume(CV), rim volume(RV), cup / disc area ratio(CA / DA), rim / disc area ratio(RA / DA), cup / disc volume ratio(CV / DV) and rim / disc volume ratio(RV / DV).Results: Superior, nasal, and mean RNFL parameters, DA,CA,RA, DV, CV, CA / DA, RA / DA, CV / DV and RV / DV significantly differed among three groups by single-factorial ANOVA. Inferior and temporal RNFL thickness significantly differed between the control and POAG groups. No significant difference was observed in RV among three groups. In the POAG group,.the maximum area under the ROC curve(AROC) of mean RNFL thickness was 0.845. The maximum AROC of optic disk parameters was RA / DA(0.998), followed by CA / DA(0.997). The AROC of CA, RA, CV, and DV were all > ***:.OCT may serve as a useful diagnostic modality in distinguishing suspected glaucoma from POAG.

In this paper, we solve the output feedback control problem of stochastic high-order planar nonlinear systems with output constraint and stochastic integral input-to-state stability(SiISS) inverse dynamics. By employing a key coordinate transformation, a stochastic nonlinear system with output constraint and SiISS inverse dynamics is converted into an unconstrained system. By skillfully constructing an observer and adopting SiISS small-gain conditions, we develop a new output feedback control design and analysis method, and prove that all the closed-system signals are bounded almost surely, the output constraint is not violated almost surely, and the equilibrium point of the closed-loop system is stochastically asymptotically stable.

文章选取《厦门经济特区年鉴(2011—2022)》数据为研究样本,运用偏最小二乘回归分析方法,构建了厦门市城镇化与农林牧渔业总产值、劳动力资源、财政支农资金、农民可支配收入的偏最小二乘回归模型,并对厦门市城镇化与农业经济协调发展关系进行实证分析。所得模型通过检验,表明模型对城镇化的解释能力较强,选取的各项指标中,农村居民人均可支配收入、农业产值、农林牧渔服务业、劳动力资源、财政支农对城镇化影响显著,是城镇化发展的主要影响因素。研究结果表明:渔业产值对城镇化有一定的解释作用,但对城镇化发展作用为负效应;牧业产值对城镇化发展影响不显著,说明目前牧业产能还比较低。为此,提出厦门应积极探索智慧牧渔业发展模式,加快渔业生产转型,稳步扩大现代水产养殖;精准规划生猪养殖规模,适度提高猪肉自给率等发展建议,为实现城乡融合发展、落实乡村振兴战略,提供合理参考。

In this study, the fixed-time stabilization problem of stochastic high-order nonlinear systems with output constraint and high-order and low-order nonlinearities is addressed. A new coordinate transformation is employed to directly convert output-constrained stochastic systems into an equivalent unconstrained *** fully extracting the characteristics of system nonlinearities and using the stochastic fixed-time stability theorem, a new design and analysis method is constructed to guarantee that the trivial solution of the closed-loop system is stochastically fixed-time stable while fulfilling the output constraint.
