| 1 | 回线源瞬变电磁法有限体积三维任意各向异性正演及分析显示文摘目前,瞬变电磁法(TEM)数据基本都是基于各向同性模型进行反演解释,这对于存在明显电性各向异性的勘探区域会产生较大的反演解释误差.为分析电各向异性对回线源瞬变电磁信号的影响方式与程度,本文通过求解离散化的全张量电导率时间域Helmholtz方程,实现了基于有限体积法的TEM任意各向异性的三维正演算法.该算法采用基于交错网格的拟态有限体积法(MFV)对时域Maxwell方程组进行空间域离散,并利用后退欧拉算法(Backward Euler Method)进行时间域离散.为提高时域电磁场的求解精度与效率,该算法将时间分段等步长算法与方程直接求解法相结合.通过对一维各向异性模型以及三维复杂各向同性模型进行测试,验证了本算法对于回线源瞬变电磁响应计算的正确性及有效性.最后,通过对几类典型电各向异性介质中大回线源瞬变电磁信号响应的分析,总结了不同电各向异性类型对TEM电磁信号的影响模式,结果表明,主轴各向异性情况下TEM信号主要受水平方向电导率的影响,倾斜各向异性对TEM信号的影响程度远大于水平各向异性,而通过水平各向异性信号能较清晰判断出各向异性主轴方向. | 刘亚军 胡祥云 彭荣华 Pritam Yogeshwar | 2019 | 地球物理学报2019，62，5： | 13 |
| 2 | Effect of seed mass on emergence and seedling development in Pterocarpus marsupium Roxb.显示文摘We investigated the effect of seed mass on emergence, seedling survival and growth of Pterocarpus marsupium Roxb., a medium to large, commercially valuable and deciduous tree species. Among the three size classes viz. small(10-12 mm), medium(13-15 mm) and large(16-17 mm), the maximum proportion of seed by number(54.12%) and dry weight(51.87%) was recorded in the medium size seed class. Seed length and seed width were greatest in the large seed class(16.50 mm, 7.33 mm) followed by medium(13.50 mm, 5.60 mm) and small(11.37 mm, 3.66 mm). Similarly, hundred seed weight(100 sw) varied from a maximum of 12.92 g in the large seed class to intermediate 10.95 g in the medium seed class and minimum of 7.02 g in the small seed class. The large seed size showed maximum emergence and shoot length over the medium and small seed class. After six months of growth, significant variations due to seed size were also observed for the growth and dry weight of P. marsupium seedlings. Seedling vigour, expressed in terms of height, collar diameter, number of leaves and dry biomass, was significantly affected by seed class. Seedlings that emerged from large seeds showed better growth and produced heavier seedlings as compared to medium and small seeds. | Yogeshwar Mishra Rimi Rawat P. K. Rana M. K.

| 13 | An improvised in vitro vegetative propagation technique for Bambusa tulda: influence of season, sterilization and hormones显示文摘Season and concentration of sterilizing agents play a significant role for establishment of aseptic in vitro shoot cultures and sprouting of nodal explants from field growing culms of bamboo species.In the present investigation the nodal segment explants of Bambusa tulda Roxb collected in different seasons and treated with various concentrations of HgCl_2 showed significant variation in aseptic culture establishment and bud break.The rainy season(July–August) recorded with highest of 78% aseptic culture establishment whereas autumn recorded with lowest 46%.Summer and winter seasons emerged to be the best period, registering>60% in vitro bud break.On the other hand, the autumn season had the lowest value for bud break,i.e.42%.Among different doses of sterilizing agent tried,HgCl_2 0.1% found to be suitable for maximum aseptic culture establishment(66%) as well as bud break(59%).However, among the interactions, summer season and the dose of 0.1% HgCl_2 exhibited maximum of 73% response for both aseptic culture establishment and bud break.MS medium(liquid) enriched with 5.0 μM BA+5.0 μM Kn[Kinetin(N6-Furfuryladenine)] with additional supplementation of 100 μM glutamine+0.1 μM IAA supported a maximum in vitro shoot multiplication of 4.75 fold.The proliferated shoots were successfully rooted on MS medium(liquid) supplemented 40 μM coumarin.The plantlets transferred to the polythene bags showed 98% survival. | Deepti Bhadrawale Jay Prakash Mishra Yogeshwar Mishra | 2018 | Journal of Forestry Research2018，29，4： | 1 |
