We adopted the spectrum analysis method and the BAYTAP_G method to analyze the geoelectric potential data at the Niijima station during 1998～2000 After the quantitative analysis of the tide response of geoelectric potential changes at the above station, we obtained some main characteristics of the tide response. Besides the tidal components with various periods such as diurnal tide, semidiurnal tide, and so on, semimonthly and semiyearly variations of tide response were also detected from the geoelectric potential data at the Niijima station.

本文通过采用频谱分析和BAYTAP-G方法对位于日本伊豆群岛的新岛台跨度达三年（1998～2000年）的地电场的观测资料进行了分析研究，对该台地电场的潮汐响应进行了定量提取与分析，得到了地电场潮汐响应的一些主要特征，例如除了存在全日分潮、半日分潮等不同周期的潮汐成分外，还呈现出明显的半月、半年等不同周期的活动规律。

Harmonic analysis of the DongSha Island sea level data shows that the most significant tidal constituents in this region are the K1 (amplitude: 27 cm) and O1 (24 cm) diurnal tides and the M2 (14 cm) and S2 (5 cm) semidiurnal tides.

东沙岛的水位资料经由调和分析，结果显示主要的分潮为全日潮K1、O1以及半日潮M2、S2，其振幅分别为27、24、14、以及5公分。

Semidiurnal tides spread more quickly in the south than in the north of Zhejiang seaboard. Diurnal tides spread more slowly in Zhoushan and Hangzhou gulf ocean areas, when more quickly in other ocean areas.

从潮波传播速度来看，半日潮波在浙南的传播速度大于浙北，全日潮波传播速度较小的区域主要集中在杭州湾及舟山-宁波海区，其它海区传播速度相对较大。

The relationship between barotropic tidal currents and sea level were established for the first 45-day period using the transfer functions and harmonic analysis, and then carry the prediction for the second 45-day period. There is very good agreement between the observed and predicted semidiurnal tidal current, the rms error is less than 3 cm s-1. However, prediction on diurnal tidal current is rather disappointing, the rms error is about 19 cm s-1, suggesting strong baroclinic tidal component may have a significant contribution to the tidal current, which is not registered in the sea level records.

利用转换函数与调和分析两种方法，验证水位预报正压潮流的可行性，将观测资料分为等长的两段时期，藉由第一段时期约45天的正压潮流与水位的关系，预报下一段时期约45天的正压潮流，结果显示半日潮流的观测值与预报值大致符合，其均方根约在3公分/秒以下；但是全日潮流的观测值与预报值的差异大，其均方根最大可达到约19公分/秒，推测其原因为斜压潮分量大而影响潮流，但是不会对水位资料造成影响。

In determining the power spectrum of the wind, Lomb-Scargle periodogram was used.The planetary waves with periods 120 hours,60hours and 35 hours, diurnal, semidiurnal and terdiurnal tides were found at height 86.4km in the zonal wind.

首先利用Lomb-Scargle周期图方法计算了大气纬向风场的功率谱，除了行星波和潮汐外，在行星波、潮汐的频率和与频率差处有明显的谱峰，双谱分析表明这些谱峰是行星波和潮汐相互作用形成的。

When semidiurnal tides move from the open sea to offing, they first get the high tide in the mouth of Samen bay, then bifurcate to two branches, one goes along the northwest direction and the other goes along southwest. And it can be easily found that the moving direction of diurnal tides is obviously different from semidiurnal tides.

半日潮波，由浙江东南外海向近海传播时，首先在三门湾湾口附近达到高潮，之后又分为南北两支，一支向西北传播，另一支向西南传播，而全日潮波与半日潮波传播方向有明显的不同。

5 In. This skink lives in a wetter forest habitat than the other Australian Skinks, is nocturnal in warm weather and diurnal in cold and feeds almost exclusively on snails and slugs.

有别於其他澳洲蓝舌蜥，桃舌蜥生活在较潮湿的环境。在温暖的季节，桃舌蜥多半在夜间活动，到了冬天则变成日型性。食性包含了各种蜗牛以及软体动物。

The results showed that the diurnal variation of net photosynthetic rate was a smooth one-peak curve in sunny day.

结果表明：(1)晴天叶片净光合速率在12点达到峰值21.19μmolCO2m^(-2)s^(-1)，日变化为平稳的单峰曲线。

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.
