The effects of feeding frequencies(1, 2, 3 and 4 times per day) on the growth of Sparus macrocephalus were studied in a 40 d growth trial under the condition of 26.8~24.5℃, 26.0~27.0 salinities for determining the optimum feeding frequency. Identical diet was selected for the mature and seedling of Sparus macrocephalus in the aquiculture system.

选取同一种饵料设置4个饲喂频率水平（分别为1次／d、2次／d、4次／d、6次／d），采用静水连续充气养殖系统，在盐度为26.0~27.0、温度为26.8~24.5℃的条件下对黑鲷成鱼和鱼种进行为期40d的生长实验。

Based on the soil fertility and fertilizer effect of Beijing brown chao soil in the way of microtrial of winter wheatsummer maizer continuous cropping,the annual grain yield and the tenyear soil organic matter change show that the crops yield,soil organic matter and soil fertility can be improved significantly by using N P K chemical fertilizers together with organic material under lower soil fertility.

通过对北京褐潮土土壤肥力和肥料效益监测基地10年定位微区试验的调查分析表明：在土壤肥力水平较低的情况下施用氮、磷、钾化肥及氮磷钾化肥与有机物料配施，具有显著提高粮食产量的作用，并较大幅度提高土壤有机质含量；随着有机物料施用量的增加，效果更为明显。

"We expect oil demand will be around 2 million barrels per day more in 2005 versus the average in 2004, so we need something like 3 million barrels per day of additional capacity globally to avoid another year of high prices," Mandil told Reuters on the eve of the 19th World Energy Congress in Sydney.

&我们预计，与2004年的平均水平相比，2005年的石油日需求量会再增加200万桶左右，因此，我们需要在全球范围内把石油日产量再额外提高300万桶左右，以避免下一年再度出现价格过热的现象。&

Methods 30 patients with trichloroethylene medicamentous dermatitis and 30 normal persons were selected as the observation group and the control group respectively; color Doppler was used to detect the spleen thickness and longitudinal length, spleen vein and artery diameters, the maximum blood velocity and blood flow of spleen vein and artery; RIA was applied to determine the serum levels of HA, LN, PCⅢ, CⅣ and CG; relevant analysis was made on the linear relationship between serum indices of hepatic fibrosis and spleen hemodynamics of the two groups.

选择30例三氯乙烯药疹样皮炎患者作为观察组，30例同时期健康体检者作为对照组，用彩色多普勒超声仪，检测脾脏厚度及长径、脾动静脉直径、脾动静脉血流量和脾静脉最大流速SPV(下标 x。用放射免疫法检测肝纤维化指标透明质酸、层粘连蛋白、Ⅲ型前胶原、Ⅳ型胶原和甘胆酸的水平，并对观察组与对照组的脾血流动力学参数与肝纤维化指标进行相关分析。

The characteristics of destruction and ground motion of the earthquakes in these regions are similar to those of meizoseismal areas of past earthquakes.

近期国内外诸多强烈地震的实际资料和相关研究成果表明，直下型地震不仅地震峰值加速度大，且竖向和水平峰值加速度比值也有别于远场地震的统计关系。

In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.

随着污水温度的降低，污泥中冷适应微生物的数量逐渐增加，但由于冷适应微生物的生长速率相对较低，且容易受到各种生态因子的抑制作用，其数量无法达到常温下中温微生物的水平，使得污泥中微生物的总体数量和活性降低。

With the experiments done in this research, effects on visual performance at mesopic region were described, which belongs to the necessary basic research work for developing the new mesopic system.

本论文研究通过选用不同的照明水平、目标大小和目标偏心度的条件进行实验，其研究成果能实现对影响中间视觉状态下视觉功能的一些因素的描述，这是建立中间视觉光度学所必须解决的基础研究工作。

This research is to find out the effects of light level, visual angle and eccentricity on the spectral sensitivity of human eyes at mesopic region; to validate the possibility of working out the spectral luminous efficacy curves based on visual performance at mesopic light levels; to find the connection between the results of performance-based method and brightness-matching method.

本论文主要研究照明水平、目标大小和目标偏心度等因素对中间视觉状态下视觉功能的光谱响应特性的影响；探讨在视觉功能的基础上获得人眼光谱光视效率的可能性以及基于视觉功能法(Performance-based Method)和传统的视亮度匹配法(Brightness-matching method)之间所存在的联系。
