Homogeneous or heterogeneous base material is selected; an alternately superimposed barrier layer and an alternately superimposed recessed layer are grown and formed at the extension of the base material; donor impurity and acceptor impurity are doped in the interface between the barrier layer and the recessed layer and in the interface between the recessed layer and the barrier layer, and the p type group III nitride material doped at a position selecting superlattice is obtained.

选择同质或者异质的基质材料；在基质材料上外延生长形成变换叠加的垒层和阱层，在垒层与阱层的界面和阱层与垒层的界面掺入施主杂质和受主杂质，得选择超晶格位置掺杂的p型III族氮化物材料，其中，每个生长周期的步骤为：生长带隙较宽的垒层，同时掺入受主杂质；生长施主杂质或受主杂质δ掺杂层；生长非掺的带隙较窄的阱层；生长受主杂质或施主杂质δ掺杂层；在N 2 气氛下对所得的选择超晶格位置掺杂的p型III族氮化物材料退火，即得目标产物。

Secondly, using the relation between the weighted modified K-functional, the weighted modulus of smoothness ,the weighted main-part modulus of smoothness . we get the pointwise direct and inverse approximation theorem with Jacobi weight for Szdsz-Kantorovich operator. Thus some results on w = 0w(x denotes the weight function, Ditzian-Totik modulus and classic modulus are extend.

其次，引入一种改变的带权K-泛函，利用带权光滑模和带权主部光滑的关系及带权光滑模与改变带权K-泛函的等价性，关于Szász-Kantorovich算子，讨论了一阶矩不为零的算子的点态带Jacobi权逼近正定理及等价定理，推广了已有的权为零及Ditzian-Totik光滑模和古典光滑模的结果。

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。

The gold-bearing metamorphic fluid migrates from migmatite zone and granite to upper mylonite zone and lower mylonite zone in the slip system.

本文重点强调：具有从上部主糜棱岩带—混合岩带—花岗岩带—混合岩带—下部主糜棱岩带的岩石垂向分带性的滑动系统是深层次推覆过程中断裂动热变质、超变质作用，以致长英质岩石部分熔融的产物。

The characteristics of density bands of Porites coral from Meiji reef in Nansha area are revealed by X-radiography of coral slabs and periodical changes of δ^18 O and δ^13 C in the skeletons.

结合珊瑚骨骼X射线照片和δ^18O、δ^13C的年际变化，对南沙群岛美济礁滨珊瑚骨骼岩心的密度条带进行了分析，发现其密度带变化模式多样，初步可归纳为如下3种类型：(1)宽度相近的高低密度条纹均匀、相间地排列，一对高低密度条带平均宽约4mm；(2)在骨骼主生长轴上由近于均匀分布的细密度条带组成。

In northeastern of basin, together with the structural framework of slope belt and the dynamical information of well, we can conclude that the gas reservoir in Taiyuan-early Shihezi formation dominantly belong to protogene depositional gas reservoir under the normal pressure, and the gas favourable reservoir belt was controled by framwork of main sandbody; But in upper Shihezi Formation to Shiqianfeng Formation the gas reservoir show the feature of secondary Tectonic-depositional gas reservoir under the extremely low pressure, and the gas favourable reservoir belt mainly locate in a zone which the low amplitude structure and main sandbody superposed in the slope belt.

5盆地东北部斜坡带构造与钻井生产动态资料的相关分析结果表明，太原组-下石盒子组气藏主体属于正常压力下的原生岩性气藏，其有利含气区带主要受控于主砂体分布格局；上石盒子组-石千峰组气藏则主要为异常低压下的次生构造-岩性气藏，其有利含气区带主要分布在斜坡带低幅度构造与主砂体叠合区。

For main-belt objects this can occur after the object has been observed on two or more nights at four oppositions (although this depends on the number and distribution of the observations as well as their quality); NEOs can receive a number after two or three well-observed oppositions.

对于主带小行星，只要在4个冲日内观测到两个或更多的夜晚（虽然这依赖观测的数量和分配以及观测的质量），就可以获得正式编号；对于近地小行星，只要获得两个或三个比较好的冲日数据，就可以获得正式编号。

You taught me the road I should walk, that I slip not over to the line of death.

主﹗你是我最知心的朋友主﹗你是我最亲爱的伴侣我的心在天天追想著你渴望见到你的面在我人生的每一个台阶在我人生的每一个小站你的手总是在搀拉著我把我带在你身边告诉我当走的路﹐没有滑上死亡线你爱何等的长阔深高﹐我心发出惊叹有了主还要甚麼﹖我心与主心相连我已起誓要跟随主﹐永不改变

After experiments, we got some results as the following:1.Induced by semi-conductor laser, solid DNA changes as below: 1the deoxyribose-phosphate backbone vibrations in DNA decreasing, these bands are at 884~890cm~(-1),1112cm~(-1) and 1168cm~(-1). 2 deoxyribose and C-O stretch vibration in d increasing, there are new bands occurring at 1436cm~(-1) and 1072cm~(-1), the intensities of these bands at 1466cm~(-1) and 1030cm~(-1) increase.

通过实验研究，得到如下一些结论： 1、固体DNA经半导体激光器照射后，可以导致以下变化：(1)DNA中脱氧核糖磷酸主链振动减弱，包括在884～890cm~(-1)、1112cm~(-1)和1168cm~(-1)处的谱带；(2)脱氧核糖以及d中CO的伸缩振动增强，在1436cm~(-1)和1072cm~(-1)处出现了新的谱带，在1466cm~(-1)和1030cm~(-1)处的谱带强度增强；(3)各碱基的振动频率和相对强度都发生了很大的变化，碱基中羰基的伸缩振动显著增强，在1650cm~(-1)和1670cm~(-1)处出现了新的谱带，在1710cm~(-1)处的谱带强度显著增强。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
