由地面重力数据确定扰动位径向二阶梯度

提出利用地面重力异常数据计算地面扰动位径向二阶梯度，将该梯度的积分表达式转换为卷形式的谱表达式，便于应用ＦＦＴ／ＦＨＴ技术进行快速计算。     

Raman microspectrometry, FT-IR and inclusion characteristics of gem garnets from Tanzania and Madagascar

Chemical composition, Raman microspectrometry, and Fourier transform infrared (FT-1R) and SEM-CL (Cathodluminescence) analyses are carried out for Tanzania and Madagascar garnets for locality identification. Inclusion study was sustained after electron probe microanalysis (EPMA). Needle-like illmenites, apatites and zircons were the most common solid inclusions in Tanzania garnets. Madagascar garnets revealed rutile needles and apatites were also observed, but differences in size, shape and distribution patterns were noticed compared to Tanzania garnets. Tanzania garnets exhibited all types of observable fluid inclusions such as ““ fingerprint““ pattern, called Type Ⅰ-A, liquid-only (L) single phase fluid inclusion, called Type Ⅰ-B and Type Ⅱ-A ( L S), Type Ⅱ-B ( L V) and Type Ⅲ-A (L Sylvite even if all examined garnets from three localities retained ““fingerprint““ features, so called, partially healed fractures, in common. Chemical composition, Raman microspectrometry and Fourier transform infrared (FT-IR) analysis taken turned out to be useful methods for the purpose of this study. Using consequences of SEM-CL and inclusion study, accordingly, the locality identification of gem-quality garnets is capable of being available in further application for other kinds of gemstones.

短信息——浙江省将建成海洋特别保护区

据浙江省政府办公厅披露，省政府日前颁布了《浙江省海洋特别保护区管理暂行办法》，明确指出，七类区域将可以设立海洋特别保护区。一旦保护区设立，将严禁从事狩猎、电鱼等行为。浙江省提出，海洋特别保护区可以开展旅游活动，但要科学确定旅游区的游客容量，合力控制游客流量，建立协调的生态经济模式。浙江是全国海岛数量最多、海岸线最长的省（市）。据悉，象山港、岱山、嵊泗、普陀、大陈岛等区域有望不久跻身浙江首批海洋特别保护区。
