In a gas/particle two-phase test facility, a three-component particle-dynamics anemometer was used to measure the characteristics of gas/particle two-phase flows in a 29 megawatt (MW) pulverized coal industrial boiler equipped with a new type of swirling pulverized coal burner. The distributions of three-dimensional gas/particle velocity, particle volume flux, and particle size distribution were measured under different working conditions. The mean axial velocity and the particle volume flux in the central region of the burner outlet were found to be negative. This indicated that a central recirculation zone was formed in the center of the burner. In the central recirculation zone, the absolute value of the mean axial velocity and the particle volume flux increased when the external secondary air volume increased. The size of the central reflux zone remained stable when the air volume ratio changed. Along the direction of the jet, the peak value formed by the tertiary air gradually moved toward the center of the burner. This tertiary air was mixed with the peak value formed by the air in the adiabatic combustion chamber after the cross-section of x/d = 0.7. Large particles were concentrated near the wall area, and the particle size in the recirculation zone was small.

作者： guan shuo Wushu Department Shenyang Sport University

The paper adopts literature consultation method, questionnaire survey method, observation method and mathematical statistics method to investigate the teaching status quo of free combat specialized course of Shenyang Sport University and analysis existing problems. It turns out that the never-changed warming-ups, the uninteresting teaching content and the careless class summary lead to a part of students lose their interest on free combat specialized course of Shenyang Sport University and some teachers are lacking in courage to innovate and unable to motivate the class air and promote students’ learning motivation. On the basis of investigation on teaching status quo of Shenyang Sport University, the paper points out that Happy Physical Education method should be blended into class to show the importance and actuality value of Happy Physical Education, which can prove that Happy Physical Education is feasible. The paper provides referential suggestions for the training of versatile physical talents of our university for the new century’s socialist modernization and promoting teaching quality.

Marfan syndrome (MFS)(OMIM 154700) is a relatively common autosomal dominant genetic disease that causes skeletal, ocular, and cardiovascular defects and was first described by a French pediatrician in 1896 (Bitterman and Sponseller, 2017). Its prevalence rate is 1/3000—1/5000, and more than 25% of cases are sporadic (Chiu et al., 2014). Studies have shown that about 90% of MFS is caused by variants in the fibrillin-1 gene (FBN1, OMIM 134797). FBN1, located on chromosome 15q21.1, encodes a macromolecular glycoprotein-fibrin 1, which aggregates to form microfibers in the extracellular matrix and distributes in various human connective tissues, such as periosteum, vessel wall, and crystal suspensor ligament. Variants in FNB1 have been reported in 65 exons, but the relationship between genotype and phenotype remains rather unclear (Sakai et al., 2016). Studies have also shown that patients with MFS and similar diseases may have variants in other related genes such as members of the transforming growth factor beta receptor (TGFBR) family (Mizuguchi et al., 2004;Sakai et al., 2006;Bolar et al., 2012;De Cario et al., 2018). For better prevention and treatment of MFS as well as for suspected MFS patients, there is a strong need for efficient genetic testing for early diagnosis and differential diagnoses of patients with related phenotypes (Aubart et al., 2018).

Congenital contractural arachnodactyly(CCA,OMIM:121050),also known as Beals syndrome,belongs to a group of rare autosomal dominant(AD)diseases of connective tissue(Maslen et al.,1997).People with CCA share many distinguishing features,such as arachnodactyly,camp tod actyly,multiple joint contractures(especially finger,elbow,and knee joints),crumpled ears,scoliosis,pectus deformities,and muscular hypoplasia(Jurko et al.,2013).It exhibits no specific geographic or ethnic predilection(Frederic et al.,2009).

直接空冷技术已经广泛应用在缺水地区的火电厂中,但环境风对空气冷凝器的安全稳定运行有很大影响。设计人员需要对空冷系统进行数值模拟,了解风场对空冷系统换热性能的影响程度。目前常规的空冷电厂数值模拟方法和工程计算软件只能给出空冷换热器的换热效率,无法直接计算出在环境风作用下的汽轮机运行背压。采用汽轮机乏汽管道内部流动换热与空冷系统所处风场的内外流场耦合计算方法,能够直接计算出各种环境条件下汽轮机的运行背压,并以某大型空冷电厂为实例进行了数值模拟验证。

公共服务改革过程中的公共需求主张存在多元冲突,其结构差异性是改革方案制定、执行、反馈等一系列过程的底层驱动因素。随着新兴媒体的普及,公众表达的海量意见能够在网络空间迅速汇集,形成“话语混沌”现象,加剧了政府识别、回应公众需求的困难。在话语制度主义的理论视阈下,将话语混沌解构为话语冲突、话语模糊、话语偏差、话语潜流四种类型,并运用话语网络-话语流,理解公共服务改革中话语混沌的动态特征。建议以信息接收、信号传递、价值协商和输出这四类治理行动为中轴,快速定位需求信息,重构政府与公众之间的话语秩序,提升公共服务改革的议程合法性和方案可行性。
