1:250000 geological mapping has further revealed the mysteries of the tectonics of the Qinghai-Tibet Plateau. The Altun Mountains are not of the Tarim massif, but a part of the Kunlun-Qilian-Qinling orogenic system; the Altun fault is a large transform fault; the Muztag-Maqên suture zone and Jinshajiang suture zone are both Variscan ones; the Songpan-Garzê area in the Triassic was a huge turbidite basin on the southern margin of Laurasia; the Gangdise belt underwent the important Indosinian orogenic movement; an ocean basin that persisted from the Paleozoic to Triassic did not exist, i.e. the so-called Paleo-Tethys or permanent Tethys was not in existence in the Qinghai-Tibet Plateau. In the Paleozoic, most parts of China, including the Sino-Korean, Yangtze and Tarim massifs and the Qinghai-Tibet Plateau, were located in south of the main ocean basin—the Central Asian-Mongolian sea way—of the Paleo-Asia ocean, belonging to the northern margin of Gondwana. The Yarlung Zangbo and Bangong -Nujiang belts were twins in the Tethyan Ocean, which began to develop into two ocean rift belts in the Triassic. The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be subducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian, Yanshanian and Himalayan stages.

1：25万地质填图进一步揭开了青藏高原地区大地构造的奥秘：阿尔金山是昆仑，祁连-秦岭造山系的一部分；阿尔金断裂确是一条大型转换断层；木孜塔格-玛沁缝合带和金沙江缝合带均是华力西缝合带；松潘甘孜三叠系沉积盆地是劳亚大陆南部边缘的浊积岩盆地；冈底斯带曾经历了重要的印支造山运动；不存在从古生代延续到三叠纪的大洋盆地，即不存在所谓古特提斯或永久特提斯；古生代时期，在青藏高原地区亦不存在具古生物，古地理分隔意义的大洋盆地，当时，包括中朝，扬子，塔里木以及青藏高原地区在内的中国大部分均位于古亚洲洋主洋盆——中亚-蒙古带之南，属冈瓦纳大陆结构复杂的北部边缘；雅鲁藏布江和班公湖-怒江带是特提斯洋中的孪生姊妹，它们均是从三叠纪起就发展成大洋裂谷带的；以雅鲁藏布江带为主洋盆带的特提斯洋，从三叠纪晚期开始消减，经历了印支，燕山，喜马拉雅3个阶段脉动式板块汇聚造山过程。

Another important yet little-appreciated cause of anticancer drug resistance is the limited ability of drugs to penetrate tumor tissue and to reach all of the tumor cells in a potentially lethal concentration. To reach all viable cells in the tumor, anticancer drugs must be delivered efficiently through the tumor vasculature, cross the vessel wall, and traverse the tumor tissue.

另一个重要的但并未受到重视的产生肿瘤耐药的原因是肿瘤药物本身具有有限的穿越肿瘤组织在肿瘤细胞中达到潜在的致死浓度，为了达到肿瘤组织中的活细胞，抗肿瘤药物必须能够有效的穿越肿瘤的脉管系统、穿越血管壁进入肿瘤组织。

The production and transmission process of Mach cone observed in many experiments has been captured in this numerical simulation. The relation between thrust, impulse coupling coefficient and one pulse laser energy, pulse width were gained, which agreed well with the experimental results by Germany Space Center.

数值仿真中明显捕捉到有关实验中观察到的马赫杆的产生与移动过程；得出了推力和冲量耦合系数随脉冲能量、脉宽的变化关系，计算结果与德国空间中心实验吻合得较好，为脉冲激光器的选择和脉冲参数优化提供了参考依据。

A high-performance modular exponentiation coprocessor, SEA, is presented here, and three novel ways are employed. First, a parallel binary modular exponentiation algorithm is used to decrease cycles, and a high radix Montgomery modular multiplication algorithm is modified to the radix based high radix Montgomery modular multiplication algorithm to increase the frequency; second when mapping algorithms to a systolic array, modular square and modular multiplication are alternatively computed to cover up the dependencies between iterations in the RBHRMMM algorithm and the bypass is used to eliminate the dependencies in the PBME algorithm; third, multipliers are split first, and then accumulations are compressed as partial products to decrease carry propagation delay in the critical path.

SEA是一种针对大数模幂的高性能协处理器，其主要采用如下3种加速方法：①采用二进位并行模幂算法和以基数长度为处理字长的高基数Montgomery算法；②将算法映射到脉动阵列处理结构，并交替计算平方和乘以掩盖RBHRMMM算法中的相关，同时应用定向技术消除PBME算法中的相关；③基於"先拆分乘法、后将累加压缩"的思想优化关键路径。

According to petrologic analysis of 18 samples of altered rock, phlogopite rock , with regard to its B 2O 3 content, it is generally restricted to the outside of the ore bed, having certain ties with the boron minerlization while no ties are found in altered rock of the same type associated with veins of diorite porphyrite.

其中金云母岩多分布在含矿层外带，通过对 1 8件金云母岩样品中B2 O3含量分析，表明正常蚀变岩中的金云母岩与硼矿有一定的关系，而由闪长玢岩脉体侵入影响下形成的金云母岩则与矿化无关。

"There are two different modulation methods commonly used to do this: pulse-code modulation, which is widely used for transmission in common-carrier communications; and delta modulation, which is finding broad application in military communications."

完成这一转换通常有两种调制方法：脉码调制，这种调制方法广泛用于普通通信传输中；增量调制，这种调制方法在军事通信中使用较多。

It appears that the relationships between the land surface heat fluxes and the heterogeneous length scale are significant, but the mesoscale heat fluxes don't indicate similar relationships with heterogeneous length scale. The representability of gridcell averaged surface fluxes is good but that of mesoscale fluxes is not so good.

这些结果表明地表水、热通量的空间分布尺度与非均匀尺度之间存在较好的对应关系，而中尺度水、热通量与非均匀尺度的关系并不明显，说明地表水、热通量的网格平均值的代表性较好，但是不能反映次网格脉动的影响，而中尺度通量的网格平均值的代表性较差。
