Considering some period of time geomagnetic data recorded at the Observatory Surlari (colatitude 45.3°, longitude 26.3°) and comparing them with data recorded at other observatories, such as Ottawa (colatitude 44.6°, longitude 284.5°), Canberra (colatitude 125.3°, longitude 149.3°), Kakioka (colatitude 53.8°, longitude 140.2°) and Vernadsky (colatitude 155.3°, longitude 295.7°), including comparison to the windowed Fourier transform, the choice of an appropriate wavelet basis function, edge effects due to finite-length time series, and the relationship between wavelet scale and Fourier frequency.

我们分析了Surlari观测台（余纬45.3°，经度26.3°）的地磁时间序列，并与Ottawa（余纬44.6°，〖JP2〗经度284.5°），Canberra（余纬125.3°，经度149.3°）， Kakioka（余纬53.8°，经度140.2°），Vernadsky〖JP〗（余纬155.3°，经度295.7°）等台站的结果进行了对比分析，讨论了Fourier变换时间窗和小波基函数选取的影响，有限长时间序列引起的边缘效应，以及小波尺度和Fourier频率的关系等问题。

The current intensity and density are higher for bothsouthward IMF and high geomagnetic activity.

场向电流的强度和密度随行星际磁场南向分量及AL的负值增加而增大。

Defining the geomagnetic field is influenced by the current-conducting wire.

结果表明：电流为2A时，单根导线距地磁场观测点距离应大于150m；导线两侧在相等距离处对地磁总场的干扰并不遵循"数值相等，方向相反"的规律，而是一侧增加量大于另一侧减少量。

A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.

揭示出近1500a来古里雅冰芯中NO3-浓度变化可以反映太阳活动的强弱变化；回答了长期争议的并直接关系到太阳发电机理论是否正确的Maunder极小期太阳活动特征问题；发现太阳活动可能存在36a左右的周期；证实了37kaBP左右古里雅冰芯记录中宇宙成因同位素36Cl含量峰值的存在，指出这一时期的宇宙成因同位素峰值事件具有全球性，弱的太阳活动和弱的地磁场是这一事件发生的原因所在；揭示出古里雅冰芯记录到的"8.2ka BP事件"，认为这一全球性事件发生的主要原因与弱的热盐环流和弱的太阳活动有关；发现古里雅冰芯记录的末次冰盛期和末次冰消期气候变化均在一定程度上滞后于太阳辐射变化，而全新世气候变化大致与太阳辐射变化同步；发现末次冰消期高原地区气候变化不仅具有北半球气候变化的某些特征，同时还具有南半球气候变化的某些特征，这说明热带地区可能对全球气候存在重要的影响。

GIC level in Northwest 750kV Planning Power Grid under the effect of uniform electric field and strong geomagnetic storm is estimated.

A model of induction electromagnetic field is also established for ocean surge in geomagnetic field base on the Maxwell theory.

8在麦克斯韦电磁理论的基础上，建立了海洋内波在地磁场中感应电磁场的理论模型。

Through the comparison of the two CMEs as well as their interplanetary responses, two primary space weather effects of them, i.e., solar energetic particle events and large geomagnetic storms, were studied.

通过比较这两次CME事件以及它们的行星际响应，分析了其伴随的两种主要空间天气效应：太阳高能粒子事件和地磁暴。
