段文燊  李显贵  吴朝容 《地球物理学进展》2002,17(3):491-497

研究了地震资料的现场处理技术－－QPOG（Quickly Predicting Oil and Gas），提出利用QPOG技术右以在地震勘探中快速有效地进行油气预测，并给出了有井区和无进区的两种预测方法；有井区以人工神经网络、模糊相似优先比等方法为主，无井区以分形、混沌、突变等理论方法为主，通过对具体研究区的实际预测，证明了方法的实用性。  相似文献   

Induction Effect and Genetic Analysis of NG to Thallus of Porphyra

The young thalli of Porphyra yezoensis and P. haitanensis are induced by N-Methy-N‘-Nitro-N-Nitrosoguanidine (NG), a strong mutagen to induce the mutant of chromatophore. It is showed that no mutants have been investigated in all control groups,while in the induced groups, it is easy to find mutant cells or mutant cell masses in the thallus.The pigmentation mutants may be the result of NG inducement. The mutant rate increases obviously with the mutagen concentration or by prolonging the induction time. Within the scope of experiment, the inducement effects of Porphyra yezoensis are raised from 11.2% to 28.7%, and those of P. haitanensis from 10.1% to 20.2%. According to our experiments, the amount of mutant cells in the same area does not increase with the induction intensity The amount of mutant cells in every group of inducement of both species of Porphyra changes very little with the fixed fields check method. The lowest dose (25μg/mL) of this experiment has a high mutant rate. The mutant rate shows the percentage of mutant cells in all the survived cells, while the amount of mutant cells reflects the effect of inducement. Thus the optimum induction concentration of NG is 25μg/mL, and the optimum induction time is 30minutes.  相似文献

The new spreading conchospores ot Porphyra yezoensis, P. haitanensis and P. katadai var. hemiphylla are induced by N-Methy-N‘-Nitro-N-Nitrosoguanidine (NG), a strong mutagen to induce the mutant of chromatophore. It is showed that (1) no mutants have been investigated in all control group. (2)The conchospores of all the three species of Porphyra are easy to be induced by NG for they are in the stage of breeding, In the lowest dose (10 μ g/mL) of this experiment, the mutant rate of P. yezoensis is up to 57.9%, that of P. haitanensis 30.7% and that of P. katadai var. hemiphylla 51.7%. (3)The mutant rate can not increase obviously by increasing the reagent concentration or prolonging the induction time. Within the scope of experiment, the inducement effects of three species of Porphyra ar e much similar, and the mutant rate is near 50%. The optimum induction concentration of NG is 10 μ g/mL, and the optimum induction time is 30 minutes.  相似文献
