By synthetically analyzing the variation characteristics of pre-earthquake anomaly before five moderate-strong earthquakes in East China since 1990,discussing the pre-earthquake anomalous shape of b value and so on we obtained the comprehensive criteria for medium and short-term earthquake anomaly before moderately strong earthquake in East China:high YH value anomaly—low b value anomaly—low C and YH value anomaly—low Ds and Dt and Σ value anomaly and high b value anomaly—earthquake.

通过对华东地区1990年以来5次中强以上地震震前异常变化的综合分析，探讨了b值，Ds，Dt，C值， YH值，Σ值震前异常形态，并归纳出华东地区中强地震发生前测震学中短期异常的综合判据：YH值高值异常(主要出现在震前3年前后)—b值低值异常(平均出现在震前2年前后)—C、YH值低值异常(大体出现在震前1～2年前后)—Ds，Dt值低值异常、Σ值低值异常、b值高值异常(主要出现在震前1年内或稍长)—发震的模式。

The SSTA of February and August in 1998 had two peaks, while the wind speed reached its maximum minus anomalies in January and August. In order to find the circulation anomaly in the South China Sea, the circulation of 19952000 had been calculated by the ECOM hydrodynamic numerical model. The elevation and circulation of January and August in 1998 indicated that there were great anomaly of elevation and circulation after this El Nio event.(1)In January, the whole South China Sea had positive sea level anomaly and anticyclonic velocity anomaly, so the cyclonic circulation was weaker than normal.(2) In August, the South China Sea had positive sea level anomaly, especially stronger in the east of Vietnam, and cyclonic velocity anomaly in south, anticyclonic velocity in north, especially strong in the east of Vietnam. So the cyclonic gyre in the north and the anticyclonic gyre in the south were both weaker than normal, and an anticyclonic gyre appeared in the east of Vietnam.

为研究南海环流在1997/1998年的异常变化，利用ECOM水动力模型计算了1995—2000年的南海环流场，分析了1998年1月和8月南海水位和环流的异常分布，二者均存在显著的异常：①1月，整个南海海盆为正的水位异常，流场为反气旋异常环流，冬季控制整个南海海盆的气旋式环流减弱；②8月，南海海盆水位为正异常，特别是越南东部海区出现较强的正水位异常，南海南部的高水位中心扩大北移；异常流场表现为南部为气旋式异常环流，北部为反气旋的异常环流，且在越南东部海区形成非常强的反气旋异常环流中心，使得控制南海南部的反气旋环流和北部的气旋环流均减弱。

As a whole, the rocks from diorite enclaves, through quartz-diorite, granodiorite to monzonitic granite, have the feature of REE slightly increasing, Eu from weakly positive transits to negative anomaly, but the diorite enclaves which has Eu negative anomaly. Besides, the Ba, Nb, Ta, P and Ti all show negative anomaly, and have positive anomalies of K and Th, simultaneously, there exists Sr positive anomaly in some rocks. Along with the increasing of the SiO〓, the P and Ti have negative anomaly, Th and K positive anomaly are obvious.

张广才岭中生代不同时期的花岗岩具有相同的Sr、Nd同位素特征，均具有高ε〓值、低，值的突出特点，ε〓值集中在-2～+4之间，〓值主要集中在0.703～0.706之间。

Before the occurrence of ENSO, due to the anticyclonic anomaly in midlatitude of the South Indian Ocean, the anticyclonic anomaly over Australia tends to be enhanced through the dispersion of Rossby wave; In the meantime, the equatorial convergence of the southerly anomaly off the east of Australia and the northerly anomaly in the Philippine excite the onsets of the westerly anomaly in the equatorial western Pacific and the occurrence of ENSO.

在ENSO发生前，南印度洋中纬度为反气旋异常，并通过Rossby波的频散作用加强了澳大利亚附近的反气旋异常；同时，澳大利亚东部沿海的南风异常与菲律宾附近的北风异常在赤道辐合，促进了赤道西太平洋西风异常的爆发和其后ENSO的发生。

The Chondrite normalized REE pattern shows typical enrichment of LREE, with ∑REE peaking up to 318 mg kg^(-1) in central layer of the profile. Both Ce and Eu have a similar trend of variation in the profile, i.e. positive anomaly-negative anomaly-positive anomaly from bottom to top. The highest ∑REE value occurs where negative Ce and Eu anomaly and relatively higher Fe(superscript 2+)/Fe(superscript 3+) values also occur.

剖面稀土元素分布型式为轻稀土富集型，∑REE在风化壳中部达到最高值318 mg kg^(-1)，剖面上Ce和Eu均呈正异常－负异常－正异常变化趋势，∑REE最高值出现在Ce和Eu负异常和Fe(上标 2+/Fe(上标 3+)较高层位，∑REE与Fe2O3显著正相关。

Theoretical calculation shows the anomaly of reservoir tidal gravity is measured at μGal level, while the measured data shows the observation error of such tidal gravity at 10-μGal level. This indicates that the data noise may well disguise real anomalies, and therefore that the lack of measured anomaly data does not necessarily equate to the lack of oil and gas reservoir underneath. The actual observed tidal gravity anomaly can reach tens of μGal. Though it is more than three times the observation error, we can not attribute it to the reservoir-induced tidal gravity anomaly.

理论计算表明，油藏潮汐重力异常在微伽量级，而实际资料表明潮汐重力的观测误差为10 μGal量级，油藏潮汐重力异常可能会被噪声淹没，所以没有观测到潮汐重力异常不等于地下没有油气；实际观测的潮汐重力异常可达数十μGal，即使超过观测误差的3倍，也不能将它直接归因于油藏产生的潮汐重力异常。

Dimensiona ultrasonography data of 29 cases fetal anomaly between 24 and 40 weeks' gestation from Jan 2003 to Dec 2006. Results Among them, there were 11 cases of cheilognathus,7 cases of anencephalus, 4 cases of anomaly of extremities, 3 cases of omphalocele, 3 cases of lymphocyst at the neck and 1 case of amniotic band syndrome. The anomaly features are consistent with those of the born fetuses. Conclusion The three??

大部分解剖结构明显异常的畸形一般通过二维实时超声在22周左右即可做出诊断［1］，但胎儿体表结构有较复杂的曲面改变，二维超声可能漏诊、误诊胎儿体表畸形。20世纪80年代末应用于临床的三维超声成像，是检测胎儿发育状况的有效方法，大大提高了产前诊断的准确率，尤其在检测胎儿畸形方面具有独特优势［2］。

So it can exactly reflects the depth of apparent resistivity of the anomaly. Furthermore, we can utilize geological datum from the borehole directly to calibrate the apparent resistivity anomaly near the borehole and reduce the ambiguity of the anomaly explanation.

在垂直地电剖面法中，由于电极是在地下供电，直流电流源的电场所受干扰比较小，电流线的走向是直接从地下到地表，场强较均匀而且场强值大，所以对深部岩溶分辨能力比较强，并可消除非岩溶体对异常的干扰，更能准确反映有视电阻率异常体的存在深度。

In this paper, the satellite gravity anomaly data are employed as pseudo free air gravity anomaly to calculate Bouguer gravity anomaly.

Meanwhile, by this method some blank abnormal areas which are worthwhile to do further anomaly inspection have been identified.

多维分形方法下土壤元素成矿预测的异常下限值确定尚无标准，文中采用元素含量矿床数目累积频率的计算方法，基于该方法提取的成矿异常区域较好地识别出了绝大多数已知矿床，同时识别出了值得作进一步异常查证的空白异常区域。
