Using regional geological, newly acquired 2D and 3D seismic, drilling and well log data, especially 2D long cable seismic profiles, the structure and stratigraphy in the deep-water area of Qiongdongnan Basin are interpreted. The geometry of No.2 fault system is also re-defined, which is an important fault in the central depression belt of the deep-water area in the Qiongdongnan Basin by employing the quantitative analysis techniques of fault activity and backstripping. Furthermore, the dynamical evolution of the No.2 fault sys-tem and its controls on the central depression belt are analyzed. This study indicates that the Qiongdongnan Basin was strongly influenced by the NW-trending tensile stress field during the Late Eocene. At this time, No.2 fault system initiated and was characterized by several discontinuous fault segments, which controlled a series small NE-trending fault basins. During the Oligocene, the regional extensional stress field changed from NW-SE to SN with the oceanic spreading of South China Sea, the early small faults started to grow along their strikes, eventually connected and merged as the listric shape of the No.2 fault system as ob-served today. No.2 fault detaches along the crustal Moho surface in the deep domain of the seismic profiles as a large-scale detachment fault. A large-scale rollover anticline formed in hanging wall of the detachment fault. There are a series of small fault basins in both limbs of the rollover anticline, showing that the early small basins were involved into fold deformation of the rollover anticline. Structurally, from west to east, the central depression belt is characterized by alternatively arranged graben and half-graben. The central depression belt of the Qiongdongnan Basin lies at the extension zone of the tip of the V-shaped northwest-ern ocean sub-basin of the South China Sea, its activity period is the same as the development period of the northwestern ocean sub-basin, furthermore the emplacement and eru

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2019年第3期9卷 235-243页

Objectives: The morbidity of dry and itchy skin was high during a person’s lifetime and it had a significant negative impact. This study aimed to investigate the positive effect of silk fibroin moisturizing cream on dry skin pruritus induced by acetone/ether-water (AEW) method in mice. Method: We established a dry skin model in mice with AEW treatment, and the control group was treated with ultrapure water. The mice in AEW model group were locally administrated with silk fibroin moisturizing cream (SilkArmor)®. The transepidermal water loss (TEWL), scratching behavior, condition of skin erythema, skin histology (by hematoxylin-eosin staining) and the results of electron microscopy were measured to evaluate the positive effect of SilkArmor on dry and itchy skin in mice. Results: The TEWL value, spontaneous scratching behavior and erythema score were significantly increased after AEW modeling compared with the control group. There was no significant difference in the TEWL value, scratching behavior and erythema score between the SilkArmor group and the control group (P > 0.05). Compared with the AEW group, the value of TEWL, scratching behavior and the erythema score of mice in the AEW + SilkArmor group were improved, with statistically significant differences (P < 0.05). Skin histopathology and electron microscopy also showed that SilkArmor had certain improvement and repairment on AEW-induced skin pathological changes. Conclusions: A dry skin model was successfully established in this experiment, showing that SilkArmor brought an obvious alleviation to AEW-induced dry and itchy skin in mice.

OBJECTIVE: To analyze part of the mechanism of electroacupuncture on Sishencong(EX-HN1) for strokerelated sleep disorders(SSD) and post-stroke cognitive impairment(PSCI). METHODS: Using a randomized controlled trial(RCT) design, 72 patients were assigned to the electroacupuncture(EA) group or the sham acupuncture(SA) group. A healthy control(HC) group was also included. Both groups were given routine rehabilitation treatment. Then, patients in the EA group were given additional electroacupuncture at Sishencong(EX_HN1). Meanwhile, patients in the SA group were given a flat-head needle sham/placebo treatment placed at the bilateral Jianyu (LI15) and Binao(LI14) line midpoints and the Jianyu(LI15) and Jianzhen(SI9) line midpoints. Before and after treatment, scales were collected and analyzed. In the second phase of the study, some subjects from the EA group were selected for functional magnetic resonance imaging(f MRI) data acquisition and comparative analysis with the HC group using a non-RCT design. RESULTS: The EA group performed better than the SA group on the Pittsburgh sleep quality index(PSQI), Montreal cognitive assessment basic(Mo CA_B), selfrating anxiety scale(SAS), and self-rating depression scale(SDS). Analysis of the f MRI showed that lowfrequency(2 Hz) electroacupuncture stimulation at Sishencong(EX_HN1) can restrain frontal sup medial right(SFGmed.R), precuneus right(PCUN.R), and posterior cingulate cortex right(PCC.R) and enhance angular left(ANG.L), parietal inf left(IPL.L) and occipital mid left(MOG.L). The functional connectivity(FC) of SFGmed.R was positively correlated with PSQI. Electroacupuncture stimulation at Sishencong(EX_HN1) can reduce the side efficiency of the whole brain connection with the Thalamus.L, Hippocampus.L, and ***.L. CONCLUSIONS: Low frequency(2 Hz) electroacupuncture stimulation at Sishencong(EX_HN1) can simultaneously improve sleep quality, negative emotions, and cognitive functions, the first two of which may be

China Welding 1995年第1期4卷 19-27页

作者： Shi Kai(Xi’an Petroleum Institute)Wang Shiyan Qiu Fengxiang and Xia Wei(Xi’an Jiao tong University)

The physics phenomena of copper and stainless steel in the process of forming friction welding joint are recorded and observed by the interrupted test *** test shows that the butt friction welding process of copper and stainless steel bar can be divided into three stages approximately: the adhesion at the beginning friction stage, the friction inside the copper and the plastic ring expansion, and the friction on the bound surface of copper-stainless steel and in stainless steel. During the process,the friction surface was transformed twice.

Real-world passive radiative cooling requires highly emissive,selective,and omnidirectional thermal emitters to maintain the radiative cooler at a certain temperature below the ambient temperature while maximizing the net cooling *** various selective thermal emitters have been demonstrated,it is still challenging to achieve these conditions sim-ultaneously because of the extreme difficulty in controlling thermal emission of photonic structures in *** we demonstrated hybrid polar dielectric metasurface thermal emitters with machine learning inverse design,en-abling a high emissivity of~0.92 within the atmospheric transparency window 8-13μm,a large spectral selectivity of~1.8 and a wide emission angle up to 80 degrees,*** selective and omnidirectional thermal emitter has led to a new record of temperature reduction as large as~15.4°C under strong solar irradiation of~800 W/m2,signific-antly surpassing the state-of-the-art *** designed structures also show great potential in tackling the urban heat island effect,with modelling results suggesting a large energy saving and deployment area *** research will make significant impact on passive radiative cooling,thermal energy photonics and tackling global climate change.
