To summarize and analyze the acupoint selection rules in acupuncture-moxibustion for stable angina pectoris. Clinical studies and literature on acupuncture-moxibustion for stable angina pectoris with definite acupoint selection were included through retrieving China National Knowledge Infrastructure（CNKI）,Wanfang Database and VIP in order to analyze the characteristics and rules of acupoint selection in acupuncture-moxibustion treatment for stable angina pectoris. It has been found that the acupoint selection of acupuncture-moxibustion prescriptions for stable angina pectoris focused on specific *** top 5 acupoints with the highest using frequency included Neiguan（内关PC 6）,Danzhdng（膻中CV17）,Xinshu（心俞BL 15）,Ziusanli（足三里ST 36） and Sanyinjiao（三阴交SP 6）. Acupuncture-moxibustion treatment of stable angina pectoris involved 12 meridians, mainly including the hand-jueyin pericardium meridian, the foot-taiyang bladder meridian, conception vessel, the foot-yangming stomach meridian, the foot-taiyin spleen meridian, and the hand-shaoyin heart meridian, etc., embodying the characteristics and rules of acupoint selection such as ＂highlighting the special treatment effect of acupoints＂＂selecting acupoints along the pericardium meridian, bladder meridian and conception vessel, combining the anterior and the posterior acupoints＂, ＂selecting the distal acupoints of spleen and stomach meridians, and focusing on specific acupoints＂, etc.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

Hot Corrosion Behavior of SiO_2–Al_2O_3–Glass Composite Coating on Ti–47Al–2Cr–2Nb Alloy: Diffusion Barrier for S and Cl

引用

Acta Metallurgica Sinica(English Letters) 2019年第5期32卷 599-606页

作者： Wen-bo Li lan-lan Liu Ying-fei Yang Sheng-Long Zhu Fu-Hui Wang Hunan Electric Power Co. Ltd. Institute of Advanced Wear and Corrosion Resistant and Functional Material Jinan University Laboratory of Corrosion and Protection Institute of Metal Research Chinese Academy of Sciences

Type Ⅰ hot corrosion behavior of SiO_2-Al_2O_3-glass composite coating based on Ti-47 Al-2 Cr-2 Nb substrate was investigated in the mixture salt of 25 wt%NaCl + 75 wt%Na_2SO_4 at 850 °C. The results showed that there was a bidirectional ion exchange between composite coating and the film of mixed salts, and the sodium ion in the molten salts penetrated into the glass matrix of composite coating, while the potassium ion in the glass matrix dissolved into the molten salts. A decrease in hot corrosion rate was achieved for the coated alloy in comparison with the bared substrate due to the composite coating acting as a diffusion barrier to sulfur and chlorine and preventing the molten salts from diffusing to the coating/alloy interface during the hot corrosion exposure. Additionally, the composite coating decreased the oxygen partial pressure at the coating/alloy interface and promoted the selective oxidation of Al to form a protective Al_2O_3 layer.

Establishment and verification of theoretical model for underwater light-sheet Scheimpflug LiDAR system

引用

Science China Technological Sciences 2025年第1期 54-61页

作者： fei FENG Guojun WU bo LIU Xu ZHAO Yafeng WU Jinghan XU Xi'an Institute of Optics and Precision Mechanics Chinese Academy of Sciences University of Chinese Academy of Sciences

The Scheimpflug imaging in the air can increase the depth-of-view and has been well studied with an accurate Scheimpflug imaging model. However, there is no corresponding underwater light-sheet Scheimpflug(ULSS) imaging *** a result, imaging accuracy cannot be ensured in the design phase, which mainly relies on the post-calibration. In this paper,the ULSS imaging model is firstly established, which gives the relationship between the pixel number and target distance, as well as that between the target distance and range resolution. A new experimental bracket and an underwater Scheimflug imaging lens were designed and developed. Based on this new device, several experiments were carried out in a pool to study the range resolution of this ULSS LiDAR, by which the correctness of the imaging model was verified. It also shows that the newly designed ULSS LiDAR can achieve a millimeter-level resolution within 8 m.

Composition and morphology of the thermal decomposition products of 3Mg（OH）2·MgCl2·8H2O nanowires

引用

Particuology 2017年第1期15卷 129-134页

作者： bo Yu lan Xiang Department of Chemical Engineering Tsinghua University Beijing 100084 China

The thermal decomposition of 3Mg（OH）2·MgCl2·8H2O （318MHCH） nanowires synthesized from agglom- erated Mg（OH）2 microspheres was investigated. The influence of heating rate and temperature on the composition and morphology of the products was investigated. Thermogravimetric-differential scan- ning calorimetry, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray diffraction showed that increasing the heating rate from I to 20 ℃/min promoted the escape of crystalline water from the 318MHCH nanowires. 318MHCH nanowires were dehydrated stepwise to 310MHCH porous nanowires from room temperature to 320℃, and then to MgO cubic nanoparticles from 420 to 700 ℃. The nanowires retained their one-dimensional morphology, until the phase changed to MgO. The immediate collapse of the one-dimensional structure was attributed to the presence of Mg-O/Cl chains.

作者： Hao Ren Gui-lan Song fei-fei Ji School of Chemistry and Chemical Engineering University of Jinan Jinan 250022 China

The flotation ofniobite, fersmite, and ilmenorutile was studied using 3 collectors with various concentration and pulp pH. The collecting property of different representative collectors was investigated. Experimental results show that diphosphonic acid is an effective collector for valuable niobium-containing minerals. A flotation recovery of 90.87%-91.7% is obtained with 75 mg/L diphosphonic acid at pH 2-4. The chemical adsorption of diphosphonic acid on these 3 minerals＇ surface might lead to the high recovery efficiency of the minerals, which is proved by IR and X-ray photoelectron spectroscopy spectra.
