The excitation functions of two very similar reaction channels, 58Fe＋ 208pb→ 265Hs ＋ 1n and 58Fe＋ 209Bi → 266Mt ＋1n are studied in the framework of the dinuclear system conception. The fusion probabilities are found to be strongly subject to the structure of the driving potential. Usually the fusion probability is hindered by a barrier from the injection channel towards the compound nuclear configuration. The barrier towards the mass symmetrical direction, however, also plays an important role for the fusion probability, because the barrier hinders the quasi-fission, and therefore helps fusion.

为了揭示斜流压气机轴向缝机匣处理各个参数对压气机性能的影响程度,本文利用数值模拟的方法,对斜流压气机进行了四个变量两个"水平"的DoE实验设计,采用析因分析方法,分析了机匣处理几何参数对压气机性能的影响,同时采用控制体方法从动量平衡的角度对扩稳机理进行了研究。研究发现:扩稳效果和效率变化往往呈现相反的变化趋势;缝长和缝的开口面积比对扩稳效果影响最明显,其余两个参数影响则相对较弱;当地流向动量通量为零的轴向位置越靠下游,机匣处理扩稳效果越明显。

The properties of nuclei belonging to the newly observed α-decay chain starting from ^265Bh have been studied. The axially deformed relativistic mean-field calculation with the force NL-Z2 has been performed in the blocked BCS approximation. Some ground state properties such as binding energies, deformations, spins, and parities, as well as Q-values of the a-decay for this decay chain have been calculated and compared with known experimentai data. Good agreement is found. The slngle-particle spectrum of the nucleus ^265Bh is studied and some new magic numbers are found, while the magnitudes of the shell gaps in superheavy nuclei are much smaller than those of nuclei before the actinium region, and the Fermi surfaces are close to the continuum. Thus the superheavy nuclei are usually not stable. The a-decay lifetimes in the ^265Bh decay chain are evaluated by different formulae, and compared with experimental data. The methods which give good agreement with the data are selected.

The existence of purinergic signaling—the idea that almost all cells of the animal/human organism are able to communicate with each other via extracellular purines—was proposed by Geoffrey Burnstock(1929-2020)in 1972[1-3].The purinergic system includes the following constituents:(1)the four main purines:adenosine triphosphate(ATP)and its metabolites,adenosine diphosphate(ADP),adenosine monophosphate(AMP),and adenosine(ADO);(2)three key enzymes,the ectonucleoside triphosphate diphosphohydrolases(E-NTPDases:NTPDase1/CD39),ectonucleotide pyrophosphatase/phosphodiesterases(E-NPP),and ecto-5’-nucleotidase(E-5’-nucleotidase/CD73),which decompose ATP into ADP,AMP,and ADO.

恒山中段高压麻粒岩区是华北克拉通新太古代高压麻粒岩最好的露头区之一,北部为强烈重熔的灰色片麻岩区,构造样式以穹窿、近水平韧性剪切带为主,中部以近东西向的右旋走滑剪切带与南部变形变质程度相对较低的岩石单元相接,后者主要的岩石类型为均匀的英云闪长质片麻岩和变质辉绿岩墙。高压麻粒岩以透镜体形式出现在北部。本文通过对恒山高压麻粒岩区构造特征和构造样式的分析,认为高压麻粒岩区主要经历了4期构造变形:①高压麻粒岩透镜体里的逆冲型韧性剪切变形和走滑剪切变形;②向南或南西的伸展变形;③右行走滑剪切;④向东或南东伸展变形。对恒山地区的高压麻粒岩的出露起决定作用的是两次伸展构造运动。
