    • An electrorheological crystalline mass of a molecule is formed by dispersing the molecule in a dispersion fluid and subjecting the molecule dispersion to a uniform electrical field for a period of time during which time an electrorheological crystalline mass is formed. Molecules that may be used to form an electrorheological crystalline mass include any organic or inorganic molecule which has a permanent dipole and/or which is capable of becoming an induced dipole in the presence of an electric field. The molecules used to form the electrorheological crystalline mass are preferably macromolecules, such as biomolecules, such as proteins, nucleic acids, carbohydrates, lipoproteins and viruses.Molecules are crystallized by a method in which an electric field is maintained for a period of time after the electrorheological crystalline mass has formed during which time at least some of the molecules making up the electrorheological crystalline mass form a crystal lattice.The three dimensional structure of a molecule is determined by a method in which an electrorheological crystalline mass of the molecule is formed, an x-ray diffraction pattern of the electrorheological crystalline mass is obtained and the three dimensional structure of the molecule is calculated from the x-ray diffraction pattern.
    • 分子的电流变结晶质量是通过将分子分散在分散液中形成的,并使分子分散体在均匀的电场中持续一段时间,在此期间形成电流变结晶团块。 可用于形成电流变结晶物质的分子包括具有永久偶极子和/或能够在电场存在下成为诱导偶极子的任何有机或无机分子。 用于形成电流变结晶团的分子优选为大分子,例如生物分子,如蛋白质,核酸,碳水化合物,脂蛋白和病毒。 通过在形成电流变结晶物质之后电场保持一段时间的方法使分子结晶,在该时间期间,构成电流变结晶质量的至少一些分子形成晶格。 分子的三维结构通过形成分子的电流变结晶质量的方法确定,获得电流变结晶团的x射线衍射图,并且从x计算分子的三维结构 射线衍射图。

    • Cooling fan with a fan wheel equipped with blades and an electric motor that has a stator and a rotor that is supported in a rotationally fixed manner on a driven shaft. For a purpose of a cost-saving and compact design of the cooling fan with low fan noise, the rotor is embodied as an external rotor with a bell-shaped pole housing encompassing the stator. The fan wheel is rotationally fixed in relation to the pole housing so that the fan wheel axially encompasses the pole housing at least partially and contacts the outer circumference of the pole housing at a number of points.
    • 具有配备有叶片的风扇轮和具有定子和转子的电动机的冷却风扇以旋转固定的方式支撑在从动轴上。 为了具有低风扇噪音的冷却风扇的成本节约和紧凑的设计,转子被实施为具有包围定子的钟形极壳体的外部转子。 风扇轮相对于磁极壳体旋转地固定,使得风扇轴线至少部分地轴向地包围磁极壳体并且在多个点处接触磁极壳体的外周。
