观测所

Eric DeWeaver, the physical climatologist on the International Polar Bear Science Team and a professor of atmospheric and oceanic sciences in the University of Wisconsin-Madison, evaluated existing climate models to identify those that best represent observed changes in sea ice - a crucial component of polar bear habitat - and which are expected to best predict future conditions in the Arctic.

Qammas with crucible steel blade are mentioned in Allan and Glimour 2000 and they also state that were carried by Lutis (the men who took care of the security of neighborhoods among other things; author's observation).

带有坩埚钢刃的Qamma在Allan and Glimour 2000中有所提到，而且是被一个叫Lutis的男子所佩带（这男子负责邻居其他东西的安全；作者的观测）。

Firstly, variables which were acquired for the above two kinds of classification system were obtained from field and laboratory investigation of the core samples as well as test of supersonic waves in drilling holes. Secondly, distribution functions and parameters of all variables are determined using statistic method. Thirdly, 20000 RMR values or BQ values and cumulative distribution function of these RMR or BQ values have been obtained utilizing Monte—Carlo method and the results are plotted. Finally, risk analysis can be made from above results.

Aiming at bottom roof caving and support impact problems induced with abrupt large scale caving upper roof in face 21303 of Daliuta mine, this paper put forward the motion parameter at roof caving and calculation formula of roof shear breaking force with the help of theorem of momentum, theorem of moment of momentum and D' Alembert principle. Roof caving process was simulated by Ansys Ls-DYNA program, and maxim impact force was got. The theoretical research outcomes in the paper were applied in face 21303 of Daliuta mine, and were accordant with actual observing status of roof caving process.

针对神东煤炭公司大柳塔煤矿活井21303综采工作面，上层采空区顶板突然大规模垮落对下层顶板及支架的突然冲击问题，文章采用动量定理、动量矩定理、达朗伯原理推出了顶板垮落瞬间的运动量及顶板切顶垮落所需要的剪力值计算公式，用ANSYS LS-DYNA程序对顶板垮落过程进行了数值计算，得到了最大冲击力，在大柳塔煤矿活井21303综采工作面对顶板垮落特征进行了实际观测和理论成果验证。

The geometry strategy of POD using carrier phase epoch-wise differency and P code is studied by the simulated data in order to achieve the decimeter accuracy level. The accessment method of POD results is also discussed. The contributions of this paper are as follows. Firstly, with the analysis of the CHAMP data, the space environment of LEOs and its influence is discussed.

本文主要工作如下：首先，结合CHAMP卫星实例数据，分析了低轨卫星所处的空间环境对GPS信号的影响，研究了6PS卫星星座和LEO卫星星座的摄动运动问题和星载GPS观测误差模型问题，建立了低轨卫星GPS测量信号仿真平台。

Finally, we analyzed the relationship between the defect modes and s defect structures. The defect mode is most obvious where the defect structure is located. This confirms the relation between the defect mode and defect structure.

最后，我们分析了光子晶体缺陷模态与缺陷结构的关系，发现缺陷模态在缺陷结构处最为明显，证实在频谱中观测到的缺陷模态，确实与所制作的缺陷结构有关。

This is found by observing the doppler shift in the frequency of the radio signals broadcast from the satellite.

这是通过观测卫星所发射的无线电信号频率中多普勒偏移来确定的。
