Aqueous magnetic fluids are prepared by the physical and chemical means, and the influence of the crafts of the preparation on the magnetic fluid characters is discussed. The capillary tube viscometer is used to measure the viscosity of the magnetic fluids in a magnetic field.

本文分别采用物理和化学方法制备了水基Fe铁磁流体和水基Fe_2O_4铁磁流体，并讨论了制备工艺对水基Fe_3O_4铁磁流体样品磁化特性、粘度特性和悬浮稳定性的影响。

Based on the introduction of ocean color mechanism, a processing flow involved MERIS data pre-processing and estimation of suspended sediment and chlorophyll concentration in Taiwan Strait was proposed. The main contents are as follows:(1) MERIS data pre-processing.

本论文在介绍水色遥感机理的基础上，提出MERIS数据的预处理流程及台湾海峡水域悬浮泥沙与叶绿素浓度反演的研究方法，主要内容包括：(1)MERIS数据预处理。

The adsorption of sodium carboxymethyl cellulose and methyl celluloseonto the ZrO2 powders in aqueous solutions and the effect of the adsorption on the stability ofZrO2 suspension have been studied.

研究了ZrO2微粉自水中对羧甲基纤维素钠和甲基纤维素的吸附作用及对ZrO2水悬浮作稳定性的影响。

You may feel you are hanging, frozen, in mid-air.

你会感觉你就像半空中悬浮着冰冻着。

The research target designs of backgroud of this paper is providing a kind of sampler that can collect Suspended Particulate Matter and plankton in the sea water in the specify deepth of sea without pollution and have no pressure mutation, and at the same time condenses these microorganism.

本文所处课题的研究目标是设计一种在供潜器使用、可以在深海指定水深处无污染、无压力突变地采集、浓缩海水中悬浮颗粒物和浮游生物的取样器。

They then coated the template with ink made of flecks of gold just 60 nanometres in diameter suspended in an aqueous solution.

接着，研究人员用一种特殊的墨水覆盖住，而这种墨水是由直径仅60纳米的黄金微粒悬浮于水性溶剂而构成的。

It is seen that the differences between sea water in red tide area and that with suspended sand in TM image are mainly expressed in TM3 and TM4 wavebands.

因此赤潮区海水与含悬浮泥沙海水在TM图像中的差异，主要在TM3和TM4波段。

The sea water with suspended sand has very high reflectivity in yellow and red wavebands; however, the reflectivity decreases sharply into infrared waveband.

含悬浮泥沙的海水，在光谱的黄，红范围，具有很高的反射率，但到红外后急剧下降。

The research on the tissue culture and cell suspension culture showed that thesuitable culture medium for inducing bud was MS supplemented with 1.5mg/L 6-BAand 0.1mg/L NAA, and for the generation-continuing multiplication was MSsupplemented with 1.5mg/L 6-BA and 0.2mg/L NAA. The rooting medium was1/2MS supplemented with 0.5mg/L IBA and the rooting rate was 45.0%. Plantletsurvival after transfer to sand was 52.5%.The induction rate of calli was66.7%～86.6% and the optimum medium was MS medium with 0.5mg/L 6-BA and2.0mg/L 2,4-D. The calli became smallest partical size, friable and had gooddispersion ability after 3 times successive transfer culture, the optimum medium wasMS medium with 0.2mg/L 6-BA and 2.0mg/L 2,4-D. Culturing these particles on sixkinds of MS liquid media with different hormone contents, the optimum medium wasselected basing on he change of the density of single-cell, the density of cellaggrefate and the mass of cell.

对蒜头果进行的组织培养与细胞悬浮培养研究结果表明：MS+6-BA1.5mg／L+NAA0.1mg／L+蔗糖3％激素组合能够较好地诱导芽的初始分化和增殖，适宜的芽苗继代增殖培养基为MS+6-BA1.5mg／L+NAA0.2mg／L+蔗糖3％；采用1／2MS+IBA0.5mg／L+蔗糖3％为生根培养基，生根率为45.0％；移栽到河沙的生根苗成活率为52.5％；愈伤组织诱导率为66.7％～86.6％，其中以MS+6-BA0.5mg／L+2，4-D2.0mg／L+蔗糖3％的培养基最佳，其诱导出的愈伤组织具有较强的增殖能力和较好的脆散结构，最佳继代培养基为MS+6-BA0.2mg／L+2，4-D2.0mg／L+蔗糖3％，且培养基中的6-BA与2，4-D浓度的比值越小，愈伤组织生长越快，结构越脆散，增殖率越高；将继代后的愈伤组织转入6种含不同激素浓度组合的MS液体培养基中进行振荡培养，在综合分析各培养基的单细胞密度，细胞团块密度，细胞生物量增长率等指标后，初步筛选出MS+6-BA0.2mg／L+2，4-D2.0mg／L培养基为较好的液体培养基。

Plunder melds and run with this jewel!
