Using NCEP/NCAR reanalysis data for the period of 1957-2001, the climatological seasonal transition features of large-scale vertically integrated moisture transport (VIMT) in the Asian-Australian monsoon region are investigated in this paper. The basic features of the seasonal transition of VIMT from winter to summer are the establishment of the summertime "great moisture river" pattern (named the GMR pattern) and its eastward expansion, associated with a series of climatological events which occurred in some "key periods", which include the occurrence of the notable southerly VIMT over the Indochina Peninsula in mid March, the activity of the low VIMT vortex around Sri Lanka in late April, and the onset of the South China Sea summer monsoon in mid May, among others. However, during the transition from summer to winter, the characteristics are mainly exhibited by the establishment of the easterly VIMT belt located in the tropical area, accompanied by some events occurring in "key periods". Further analyses disclose a great difference between the Indian and East Asian monsoon regions when viewed from the meridional migration of the westerly VIMT during the seasonal change process, according to which the Asian monsoon region can be easily divided into two parts along the western side of the Indochina Peninsula and it may also denote different formation mechanisms between the two regions.

Caution to Apply Magnetic Barkhausen Noise Method to Nondestructive Evaluation of Plastic Deformation in Some Ferromagnetic Materials

引用

Chinese Journal of Mechanical Engineering 2019年第6期32卷 85-91页

Magnetic Barkhausen Noise(MBN) method is known as an effective nondestructive evaluation(NDE) method for evaluation of residual stress in ferromagnetic materials. Some studies on the feasibility of the MBN method for NDE of residual strains were also conducted and found applicable. However, these studies are mainly focused on the state of residual strains which were introduced through a one-cycle-loading process. In practice, however, structures may suffer from an unpredictable and complicated loading history, i.e., the final state of plastic strain may be induced by several times of large loads. Whether the loading history has influences on MBN signals or not is of great importance for the practical application of the MBN method. In this paper, several ferromagnetic specimens with the same final state of residual strain but of different loading history were fabricated and inspected by using a MBN testing system. The experimental results reveal that the loading history has a significant influence on the detected MBN signals especially for a residual strain in range less than 1%, which doubts the feasibility to apply the MBN method simply in the practical environment. In addition, micro-observations on the magnetic domain structures of the plastic damaged specimens were also carried out to clarify the influence mechanism of loading history on the MBN signals.

Efficient Breeding and Cultivation of Type 2 Red-fleshed Apple Cultivars Using a Search System for Suitable Apple Cultivar Combination

引用

Horticultural Plant Journal 2018年第6期4卷 219-225页

作者： SHOGO matsumoto LI Tianzhong SHUNGO Otagaki LI Yang BAI Songling Graduate School of Bioagricultural Sciences Nagoya University Laboratory of Fruit Cell and Molecular Breeding China Agricultural University Zhejiang Provincial Key Laboratory of Horticultural Plant Integrative Biology Zhejiang University

As apple possesses self-incompatibility, knowledge of the S-genotypes is very important for apple breeding and cultivation. We investigated the S-RNase genotypes of 13 type 2 red-fleshed apple cultivars and 8 lineages. All of the investigated type 2 red-fleshed apples contained the S3-RNase allele closely linked to the red-fleshed trait. We made a search system for ovule parents to efficiently produce new type 2 red-fleshed cultivars based on the S-RNase allele information(http://***/～hort/apple/red/). More than 90% of progenies from crossing a selected white-fleshed ovule parent with a type 2 red-fleshed pollen parent are expected to show the red-fleshed phenotype. We also compiled a database of the S-RNase genotypes of more than 1 000 apple cultivars, including a survey system of cultivar combinations showing those that were fully incompatible, semicompatible and fully compatible, written in Chinese(http://***/～hort/apple/ch/) and Japanese(http://***/～hort/apple/ja/).

Curvature derived from LiDAR digital elevation models as simple indicators of debris-flow susceptibility

Journal of Mountain Science 2019年第1期16卷 95-107页

To mitigate the damage caused by debris flows resulting from heavy precipitation and to aid in evacuation plan preparation, areas at risk should be mapped on a scale appropriate for affected individuals and communities. We tested the effectiveness of simply identifying debris-flow hazards through automated derivation of surface curvatures using LiDAR digital elevation models. We achieved useful correspondence between plan curvatures and areas of existing debris-flow damage in two localities in Japan using the analysis of digital elevation models(DEMs). We found that plan curvatures derived from 10 m DEMs may be useful to indicate areas that are susceptible to debris flow in mountainous areas. In residential areas located on gentle sloping debris flow fans, the greatest damage to houses was found to be located in the elongated depressions that are connected to mountain stream valleys. Plan curvaturederived from 5 m DEM was the most sensitive indicators for susceptibility to debris flows.

Applications of same-beam VLBI in the orbit determination of multi-spacecrafts in a lunar sample-return mission

引用

Science China(Physics,Mechanics & Astronomy) 2010年第6期53卷 1153-1161页

作者： GOOSSENS Sander KIKUCHI Fuyuhiko matsumoto Koji HANADA Hideo National Astronomical Observatory of Japan

Same-beam VLBI means that two spacecrafts with small separation angles that transmit multi-frequency signals specially designed are observed simultaneously through the main beam of receiving antennas. In same-beam VLBI,the differential phase delay between the two spacecrafts and the two receiving antennas can be obtained within a small error of several picoseconds. As a successful application,the short-arc orbit determination of several hours for Rstar and Vstar,which are two small sub-spacecrafts of SELENE,has been much improved by using the same-beam VLBI data together with the Doppler and range data. The long-arc orbit determination of several days has also been accomplished within an error of about 10 m with the same-beam VLBI data incorporated. These results show the value of the same-beam VLBI for the orbit determination of multi-spacecrafts. This paper introduces the same-beam VLBI and Doppler observations of SELENE and the orbit determination results. In addition,this paper introduces how to use the same-beam VLBI for a lunar sample-return mission,which usually consists of an orbiter,a lander and a return unit. The paper also offers the design for the onboard radio sources in the lunar sample-return mission,and introduces applications of S-band multi-frequency same-beam VLBI in lunar gravity exploration and applications during all stages in the position/orbit determinations such as orbiting,landing,sampling,ascending,and docking.
