恒定

The force for filtering and backwashing is from water press and pump pressure.The pressure in filtering chamber will keep same.The solution will be filtered out from inner chamber of filtering core.The solid impurity will remain on the inner surface of filtering coThe pressure difference between outer and inner chamber and.filtering resistance will be increase.

该机的过滤和反冲洗推动力均原水压头或泵杨程提供，系统滤腔的压力基本保持恒定，液体从滤芯的内腔向外流动，夹带的固体杂质被截流在过滤介质的内表面，引起内外腔压差升高，过滤阻力逐渐增大。

在最简单的情形下，一个失真器产生恒定的实的失真(16)，另一个产生正比于频率f的失真，如此类推。

The relatively constant values of open circuit voltage suggest the electrolyte layer withstands thermal shock due to high thermal conductivity and excellent ductibility of the metal substrate.

相对恒定的开路电压显示，电解质层经受住了热冲击，此受益于金属支撑体良好的导热性和延展性。

Methods: Micropicture analysis instrument was used to measure the embolic level of microspheres which were poured through ascending aorta.

在微球的大小及靶区血管分布恒定的情况下，灌注的技术因素无疑是影响栓塞平面最主要的因素。

Simmer. Results: Immunohistochemistry showed that the temporal and spatial expression patterns of AMELX, AMBN and ENAM in ameloblasts and enamel matrix were different. With the mineralization of enamel matrix, expression of AMELX decreased, but it weakly expressed in adjacent bone.

结果：免疫组化结果显示，三种蛋白在三种小鼠牙胚的成釉细胞、釉质、牙本质中的表达存在时空顺序差异，随着牙胚发育和釉质成熟，AMELX呈递减表达，而AMBN和ENAM则较恒定表达。

Most parameters for the mixture antioxidation oil were studied and they were consistent with GB 2536-90, including transparence, smell, density, solidifying point, flash point, viscosity, acids and water-solubility acids;The viscosity of the antioxidation oil at 20℃～90℃was as same as mineral;And the relative permittivity at 30～106Hz was invariable and it was higher than mineral oil so that the electric field of the antioxidation oil paper insulation was more equilibrious.

研究得到了所研制的抗老化变压器油的参数值：透明度、气味、密度、凝点、闪点、运动粘度、酸值及水溶性酸或碱等，均满足变压器油技术标准GB 2536-90的要求；20℃～90℃之间该油运动粘度和矿物油几乎相等；在30～106Hz频率范围内，该油相对介电常数基本维持恒定，且比矿物油相对介电常数略大；其工频击穿电压远高于矿物油。

In mammals, iron balance is maintained by meticulous regulation of iron absorption from the duodenum, which responds to body iron stores and erythropoietic iron demand.

动物体内铁的恒定受到小肠细胞的严密调控，小肠对铁的吸收能力与体内铁贮存量与造血组织需求量有关。

Upon a salinity challenge, euryhaline teleosts immediately regulate the functions of many ion transporters and enzymes in the gill mitochondria-rich cells for maintaining their internal homeostasis.

当广盐性鱼类面对环境盐度改变时，鱼类鳃上皮细胞许多位於富含粒线体细胞(mitochondria-rich cell， MR cell)的离子通道就必须及时运作以维持鱼体内的渗透压恒定，由於大多数的离子通道都是需要耗能的主动运输，故鳃是个需要大量能量的器官。
