The Centr al Tethys Region lies in Hoh Xil-Bayan Har. Since Late Palaeozoic, the back-ar c bathyal basin continued to break and spread. The typical oceanic crust was event ually formed in Carboniferous and Permian. The Ocean during that period is named the Paleo-Tethys, of which the remnant is the Third and the Fourth suture zone s.

特提斯中区位于可可西里—巴颜喀喇，古生代晚期以来在弧后盆地基础上继续破裂、扩张，典型的洋壳形成于石炭—二叠纪，这个时期的洋称古特提斯，它的遗迹为第三和第四缝合带。

Giving the more explicit boundary conditions and using Biconjugate gradients stabilized method to solve the linear algebra equation with large coefficient matrix, we get a fast algorithm of highprecision to calculate effectively electrical and magnetic fields in the whole space.

由于提出了简洁的边界条件，采用了解大型系数矩阵方程组的双共轭梯度稳定解法，所实现的三维交错采样有限差分数值模拟算法具有迭代收敛稳定、计算精度高、速度快等特点。

Combination of duodenoscopy,laparoscopy and choledochoscopy is an effective and safe treatment with less trauma for cholecystolithiasis with choledocholithiasis,when indications and contraindications were controlled strictly.

A trivalent plant expression vector containing Bt cry1Ah gene, cry1Ie gene and glyphosate-tolerant 2mG2-epsps gene was constructed, glyphosate isopropylamine salt as a screening agent, 2mG2-epsps gene as a selectable maker gene. The vector was transfer into maize immature embryonic calli by microprojectile bombardment, and 69 T0 generation plants were obtained. PCR analysis showed that 17 plants had the integration of insect-resistant cry1Ah, cry1Ie gene and glyphosate-tolerance 2mG2-epsps gene.

同时构建了含有Bt cry1Ah和cry1Ie基因和耐草甘膦2mG2-epsps基因的三价植物表达载体，通过基因枪轰击法转化玉米愈伤组织，以2mG2-epsps为筛选标记基因，以草甘膦异丙胺盐作为筛选剂，获得T0代转化植株69株，PCR检测结果表明：有17株已完整的整合有抗虫基因cry1Ah、cry1Ie和耐草甘膦基因2mG2-epsps的3个目的基因，RT-PCR分析外源基因可以正确转录，已获得结实转基因植株。

In 1990, Kristian Lindgren , working at the Neils Bohr Institute in Copenhagen, expanded these coevolutionary experiments by increasing the population of players to 1,000, introducing random noise into the games, and letting this artificial coevolution run for up to 30,000 generations.

1990年，在哥本哈根尼尔斯波尔研究院工作的克里斯蒂安林德格雷将这个共同进化实验的参与人数扩展到一千人，同时将随机干扰引入游戏，使这个人造的共同进化可以繁衍到三万代之多。
