玛纳斯河洪水规律及其影响因素分析

高山冰川作用流域的洪水径流,是能量,水量平衡和冰川调节的产物,它由冰川融水、积雪融水和一些有效液态降水组成。本文以玛纳期河为例,研究了洪水的发生类型,特征和形成机制,并用数理统计方法分析找出了影响洪水的主要因素。     

由5个国际超导重力仪台站资料检测到的秘鲁8.2级大地震所激发的球型自由振荡现象

综合分析了国际上5个超导重力仪台站所观测到的6组资料, 利用资料迭积的傅氏分析和最大熵谱分析检测到地球自由振荡谱, 并准确获得了₀S₀ ~ ₀S₄₈的全部振型. 将检测结果与以前3组模型及3组观测结果进行比较, 观测到秘鲁地震与阿拉斯加地震激发的₀S₂振型周期的差异, 有可能反映了地球内核各向异性. 另外, 在分析₂S₂振型谱线分裂时, 发现自转方向和逆自转方向上的谱线分裂不对称因子之间存在较大差异.     

我国深部层系的划分及其有利石油地质条件

欧美一些国家常把埋深超过4 000 m的储层称为深层,但在我国却很难用统一的深度标准来划分.根据不同盆地现已勘探开发的主力油气层系,来确定盆地深部层系的范畴更具有实际勘探意义.……

The blown sand disaster to the Tarim Desert Highway in Xinjiang, China

The Tarim Desert Highway in Xinjiang, China, the longest one in the world, has a lengthof 562 km, about 80% of which runs across, from north to south, the Taklimakan Desert. Obviously,the main problem of the road maintenance is the blown sand disaster. The research resultsshowed: (1) the physical environment along thedesert highway is characterized by strong winds,fine and loose ground materials, different dunes and so on, which provides the dynamical conditionand material source for the formation of blown sand disaster to the road and its shelter system.Meanwhile, the trend and cross-section of the road and the structure of the shelter system, asdamage objects, play important roles in the formation process of blown sand disaster; (2) theblown sand disaster to the shelter system is original from the intrusion of the drift sands and mobiledunes outside the shelter system, and the wind erosion and sand deposit caused by the air streamchanges on the ground in the shelter system. The main damage object in the Tarim Desert High-way is the shelter system presently. The damage forms include wind erosion, sand burying anddune covering; and (3) the damaged length of the blocking sand fences is 83.7%, 88.4%, 72.4%,72.8% and 40.3% and the damaged area of the straw checkerboard belts is 73.1%, 58.2%, 44.5%,35.4% and 36.6%, in turn, in 5 different landform units from north to south, and, the disasters tofences and the straw checkerboard belts are 79.5% and 57.6% in the compound dunes while theyare 64.6% and 37.7% in the interdunes respectively.     

颗粒物与天然水体痕量有机物相互作用的动态模型

在颗粒物对水中邻苯二甲酸酯吸附、水解、生物降解和藻类富集实验的基础上,提出了颗粒物与天然水体中痕量有机物相互作用的动态数学模型.用该模型研究了邻苯二甲酸二甲酯和邻苯二甲酸二辛酯在水库中的各相浓度分布.结果表明,大多数的污染物存在于藻体和颗粒物上.
