其季节

On the basis of the 1 degree girded data of the seasonal mean temperature and salinity at standard levels in the South China Sea, mean Brunt-Visl frequency profiles were derived in order to compute numerically the vertical normal-mode for different seasons in various part of the South China Sea, and the associate linearized equation for horizontal large-scale waves is solved numerically with a improved thompson-Haskell algorithm.

根据南海1°×1°网格的标准层季节平均温、盐度资料，在未引入Boussinesq近似条件下，采用改进的Thompson-Haskell算法求解线性化斜压海洋水平大尺度波的垂直结构方程，从而得到了南海各网格点的第一斜压重力波相速度和相应的罗斯贝变形半径，并探讨其地理分布和季节变化特征，以期有助于南海环流和中尺度涡旋以及有关海洋侧边界效应的研究。

The seasonal variation of upward transport is consistent with the variation of the large scale circumfluent.

Because its production season often is the season which produces with difficulty under the open ground natural environment, therefore said that it is "the counter-season cultivation","the forcing culture".

由于其生产季节往往是在露地自然环境下难以生产的季节，故又称其为"反季节栽培"、"促成栽培"。

2Nd, hydrology condition this project is situated at north Yangtze River, its hydrologic remime is as follows: Yangtze River history maximum high-water: 45.22m (in 1998) Yangtze River history most low water level: 30.37m Yangtze River mean water level: 35.745m Yangtze River average sand content: 1.16kg/m3 the subsoil water level (water volume is rich, water quality good): after 0.8m the Three Gorges Dam completes, the Yangtze River Shashi hydrologic station's water level, will rise 1-2 meters equally in the waterless season, the ample flow season will drop above equally 1-2 meters, both are advantageous to the flood prevention, and can guarantee that 3000 tonner barges year to year normally navigate and anchor.

水文条件该项目地处长江北部，其水文情况如下：长江历史最高水位：45.22m（1998年）长江历史最低水位：30.37m 长江平均水位：35.745m 长江平均含砂量：1.16kg/m3 地下水位：0.8m 三峡大坝建成后，长江沙市水文站的水位，在枯水季节将平均上升1—2米，丰水季节将平均下降1—2米以上，既有利于防洪，又能保证3000吨级驳船的常年正常航行和停靠。

All the analysis was done using SAS EM 4.1 software. The prevalence of tracheobronchitis were higher in spring and autumn. Average atmospheric pressure, average temperature, highest air temperature, lowest air temperature, water-vapour pressure, degradation of visibility were positively correlated with the prevalence of tracheobronchitis. Factors that affected the incidence of tracheobronchitis were average atmospheric pressure, degradation of visibility, daily temperature difference and water-vapour pressure.

结果］湖州市气管支气管炎门诊人数存在明显的季节分布差异，夏季和冬季是此类疾病的2个高发季节，而春季和秋季门诊人数较少；其门诊人数与平均气压、平均气温、最高气温、最低气温、水汽压、大气能见度等气象条件存在较好相关性；影响气管支气管炎门诊人数的主要气象因子有平均气压、能见度、日较差和水汽压，当平均气压≥1020.33hPa且能见度＜6.2km时，气管支气管炎门诊人数最高。

The concentration of chlorophyll a was higher in the aquacultural area,and had no distinct seasonal changes,whereas...

调查海区表层海水叶绿素a含量在近岸养殖区较高，季节变化不明显，但其粒级结构有较大的季节差异；初级生产力的平面分布与叶绿素a含量在春、秋季均较一致，其粒级结构与叶绿素a的粒级结构在春季基本一致，但在秋季有较大差异。

The variation of digestive enzyme activities in the stomach,intestine and hepatopancreas in Sparus macrocephalus in different seasons and different reaction temperatures was studied.

为从黑鲷季节变化规律中循找其饵料配置的科学依据，试验研究了黑鲷胃、肠及肝胰脏中蛋白酶、淀粉酶和脂肪酶等3种主要消化酶在不同季节、不同反应温度下的活力变化。

According to seasonal change of soil moisture, it can be divided into stable period , consumptive period (June-September) and slow restorable period (September-October).

各植物群落土壤水分亏缺可分为重度、中度和轻度亏缺三种类型，且其季节变化明显；群落对土壤水分亏缺的适应对策因植物种而异。

It is irrefutable that the US economy is slowing from its torrid pace of growth but with everything hinging upon housing, the fact that the housing market has yet to crash is still giving the Fed a good excuse to continue to tighten.

不可否认的是，美国经济增长速度放慢，但其季节调整后，事事要有住房事实上，房屋市场仍尚未给予坠机喂好借口继续收紧。
