New available geological and geochemical data of volcanic rocks indicate the coexistence of an islandarc system in the Gangdese and an extensional setting in the Himalayas during the Early to Middle Permian. Peraluminous Stype granites near Pikang (~263 Ma), the Songdo eclogite of the same metamorphic age (~262 Ma), and the regional angular unconformity between the Middle and the Upper Permian from the same geotectonic location suggest that the presentday Gangdese Retroarc Uplift Belt experienced a syncollisional orogeny at the latest Middle Permian (~263 Ma).

新的地质和地球化学资料显示早-中二叠世时俯冲背景和伸展背景共存于现今的冈底斯带和喜马拉雅带，中二叠世末期(大约263 Ma)侵位的皮康过铝质S型花岗岩以及同期发生的松多榴辉岩的高压变质作用和区域性角度不整合指示现今的冈底斯弧背断隆带在那时经历了同碰撞造山事件。

The basalt is belong island arc tholeiite and series of the calc-alkaline,and have character of island arc in rare earth element and trace element.

玄武岩属岛弧拉斑玄武岩和钙碱性系列，属太平洋型钠质类型，稀土、微量元素显示具岛弧特征，大地构造位置为岛弧中心靠近大洋一侧，与南侧那拉提晚泥盆—早石炭世侵入岩共同组成火山弧，同为古亚洲洋向北俯冲的产物。

And a new method determining threshold velocity is proposed. The threshold velocity determining by this method agrees with that by empirical results. Also the relation of the threshold velocity and frequency of explosion is analyzed.

在此基础上提出了一种确定安全速度阈值的方法，并确定了爆破荷载作用下黄麦岭磷矿采场岩质边坡的安全速度阈值，分析了安全速度阈值同爆破荷载频率之间的关系。

For example, we study the properties of the"centroid curve" and the"auxiliary curve", and identify two planes in which these two curves are defined respectively; we also use the idea of homotopy method to prove a fact that the orbit of a differential system has no triple contact point with the line we considered. Another key technique, which we use several times, is deformation argument.

例如研究由Abel积分之比定义的"质心曲线"和"辅助曲线"的几何性质，并把这两条在不同平面上定义的曲线放在同一坐标系中考虑；利用拓扑中同伦的思想来证明微分系统的轨线不可能与某条直线三重相切；利用几何方法与分析计算相结合证明了某一曲线是正则的；以及连续变动参数的技巧。

BmK IT2 is worthy of being considered to be a kind of new algesia peptide drug.

BmK粗毒和BmK I诱导的大鼠脊髓背角氨基酸类神经递质的释放采用微透析采样与高效液相色谱荧光检测技术，分析BmK粗毒和其主要致死成分BmK I诱发炎症痛过程中同侧脊髓背角氨基酸含量的动态变化。

Methods 12 guinea pigs of 20 months with 3 cm×3 cm hair sheared from their backs were divided into control group and experimental group. Rhodosin and deer serum preparation was besmeared on the skin of guinea pigs in experimental group, and cosmetic matrix was besmeared on the skin of animals in control group for 60 d. The distribution of type Ⅲ collagen was observed with Sirius red staining and HE staining. The fission index of the cells of stratum basale, the thickness proportion of stratum corneum to epidermis, the volume density of the collagen fibers and small blood vessel in dermis, the number of fibroblasts in aging skin were meassured with technique of sterology.

背部被剪去3 cm×3 cm毛的12只20月龄豚鼠被随机均分为给药组和对照组，给药组涂抹红鹿制剂，对照组涂抹化妆品基质，连续涂抹60 d；应用天狼猩红、HE染色和体视学技术分别观察和测定老化皮肤中Ⅲ型胶原的分布、表皮基底层细胞的分裂指数、角质层同表皮厚度的比例、真皮胶原纤维和微血管的体密度和成纤维细胞的数目。

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其同之处，手术前很难确诊。
