用不同剂量60Co-γ射线辐射处理整株蟹爪兰后,测定叶片可溶性糖、淀粉、蛋白质、叶绿素、类胡萝卜素等含量。结果表明:在处理后可溶性糖含量均比对照有不同程度的增加;淀粉含量呈现先增加后降低的趋势,其中在60Gy时达到最大;蛋白质含量则变化不一,但在20Gy时有一最大值;叶绿素含量和类胡萝卜素含量较对照也有不同程度的增加,且均在60Gy时含量最大;可溶性糖含量与辐照剂量呈正相关,类胡萝卜素含量与叶绿素a含量呈正相关,叶绿素a/叶绿素b与叶绿素b呈负相关,所以60～70Gy剂量处理蟹爪兰较为适宜。

Periodic wave solutions and solitary wave solutions to a generalized （3＋1）-dimensional Gross Pitaevskii equation with time-modulated dispersion, nonlinearity, and potential are derived in terms of an improved homogeneous balance principle and a mapping approach. These exact solutions exist under certain conditions via imposing suitable constraints on the functions describing dispersion, nonlinearity, and potential. The dynamics of the derived solutions can be manipulated by prescribing specific time-modulated dispersions, nonlinearities, and potentials. The results show that the periodic waves and solitary waves with novel behaviors are similar to the similaritons reported in other nonlinear systems.

Using the standard truncated Painlev expansion, the residual symmetry of the(2+1)-dimensional modified dispersive water-wave system is localized in the properly prolonged system with the Lie point symmetry vector. Some different transformation invariances are derived by utilizing the obtained symmetries. The symmetries of the system are also derived through the Clarkson-Kruskal direct method, and several types of explicit reduction solutions relate to the trigonometric or the hyperbolic functions are obtained. Finally, some special solitons are depicted from one of the solutions.

Nonlocal symmetry and explicit solution of the integrable Alice-Bob modified Korteweg-de Vries(ABm Kd V) equation is discussed, which has been established by the aid of the shifted parity and delayed time reversal to describe two-place events. Based on the Lax pair which contains the two-order partial derivative, the Lie symmetry group method is successfully applied to find the exact invariant solution for the AB-m Kd V equation with nonlocal symmetry by introducing one suitable auxiliary variable. Meanwhile, based on the prolonged system, the explicit analytic interaction solutions related to some specific functions are derived. Figures show the physical phenomenon, that is, "the shifted parity and delayed time reversal to describe two-place events".
