条件观测

In the National Natural Science Fund Project, supported by the Institute through 10 years in a row on the lake dried up Ebinur region of proliferation and the accumulation of observations and sampling analysis found that,Lop Nur, the Ebinur Lake, Xinjiang艾丁湖region is the main source of salt dust, from the bottom of the lake dried up Ebinur region of dust is an important source of salt dust material, Salt in the region of the frequency of dust storms has created extremely favorable conditions.

据中科院新疆生态与地理研究所吉力力阿不都外力研究员介绍，在国家自然科学基金项目支持下，该所通过连续10年对艾比湖地区干涸湖底的扩散和堆积进行观测和取样分析发现，罗布泊、艾比湖、艾丁湖地区是新疆盐尘暴的主要策源地，源自艾比湖地区干涸湖底的粉尘是重要的盐尘暴物质来源，为该地区盐尘暴的频发创造了极为有利的条件。

According to the datas from field investigation, lab experiment and slope run-off plot observation, the hydrologic functions of forest canopy, lower shrub, litters and soil layers have been studied. The canopy precipitation interception characteristic of different vegetation types have been analized. The results indicate that the broad-leaf forests and coniferous and broad-leaf mixed forests are better than phyllostachys pubescens forests and shrubs in canopy rainfall interception. And the litters water-holding ability of broad-leaf forests and mixed forests are higher than others. And the soil water-holding and infiltrating ablility of broad-leaf is good.

根据野外调查、试验及坡面径流小区的观测数据，研究了库区主要类型植被林冠层、灌草层、枯落物层和土壤层的水文功能，分析了不同降雨条件下不同类型植被的林冠截留特征，指出在林冠截留方面阔叶林、针阔混交林比楠竹林、灌丛的截留能力强；分析了库区主要类型林地枯落物层的水文功能，研究结果表明：阔叶林林地枯落物的持水能力普遍高于针叶林，而混交林枯落物的持水能力要比纯林大；林地土壤层的水文功能剖析表明：阔叶林林地土壤的持水性能较强，其林地土壤的入渗性能较好。

There are three constraints on the rheological structure of the lithosphere, namely, constant strain rate, constant tectonic force and the strainratedependent force. However they can not describe the realistic distribution of the strain rate in the lithosphere.

对目前存在的3种应变率约束条件（常应变率，常构造力，与应变率有关的构造力约束）进行了讨论，它们都不能真实地反映岩石圈内的应变率分布及实际观测。

A pass of a basketball or an ice hockey puck that enables a teammate to score a goal.28174. A pass of a satellite occurs whenever it rises above the observer's horizon; a visible passoccurs when all three of the above conditions are satisfied, so the sunlit satellite is seen against a dark sky - this will generally occur either shortly after sunset, or shortly before sunrise.

不论卫星何时从观测者地平线之上穿过，都会形成卫星路径；但是卫星经过的&可见路径&只有在满足上面所有三个条件的时候才可以形成，有此看来，只有被日光照射的人造卫星必须与暗背景对比才能被观测到-这经常要在太阳刚刚落山或者太阳将要升起之前。

We used different methods to calculate luminosity in order to assure its reliability. Structure function method is adopted to derive the radiatively corrected cross section whose accuracy is up to 1%. The corrections from vacuum polarization and effect of energy spread are also studied. The final analytical approximation formulaes of the observed cross sections are worked out. Different fitting methods are carried out to fit the resonances according to different requests.

模拟的分布图的仔细对比，并兼顾实验的要求，得到每种事例对应的选择条件，特别是在处理积分亮度时，更是采用了不同的方法，以保证亮度计算的可靠性；采用结构函数的方法推导出截面的辐射修正公式，精确度达到了1％的水平，研究了真空极化给拟合公式带来的修正，并考虑了束流能散的影响，计算出最终的观测截面的解析近似式；对于三个共振态的拟合，针对不同的要求，采用了不同的拟合方法；同时在M.C。

The ray-path integrated growth is much smaller than that in electrojet conditions for the same values of driven electric field |ED| because the vertical component of group veloci...

在这一高度范围，波可能是不饱和的，增大L_N，使波在h=105km饱和的临界电场│E_D│值减小。上述计算结果可解释某些在反向电射流条件下，在Addis-Ababa观测到的10m波长雷达回波的特性。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
