By comparison, the U-beam particle separator is designed to operate efficiently with a flue gas velocity of only 26 ft/s (8 m/s) at full-load operating conditions.

在满负荷运行时，通过比较，U型钢颗粒分离器的烟气流速只要设计为26ft/S(8m/s)，就能有效工作。

The state equation of induction motor with G-type parameters was established and a flux observer was designed based on U-N model. The speed adaptive law was deduced by the theory of Lyapunov stability. A method of model reference adaptive speed estimation based on the full order flux observer was proposed and a scheme of induction motor direct torque control without speed sensor was studied.

建立了基于异步电机G-型参数的状态方程，给出了基于U-N模型的定子磁链观测器；基于李雅普诺夫稳定性理论推出了速度自适应律，给出了基于这种全阶磁链观测器方案的模型参考自适应速度辨识方法。

ES cells were maintained on gelatin-coated dishes in Iscove's modified Dulbecco medium containing 0.1 mmol/L of nonessential amino acids, 2 mmol/L of L-glutamine, 0.1 mmol/L of monothioglycerol, 15% fetal bovine serum, and 1000 U/mL leukemia inhibitory factor. Embryonic bodies were firstly formed by ES cells with hang drip method in IMDM without LIF. Six-day-old EBs were trypsinized and the cells were resuspended at a concentration of （3-4）×109 L-1 cells per 1 mL of a 1:1 mixture of culture medium and Matrigel?

实验方法：将鼠胚胎干细胞株接种于被覆明胶的培养瓶内，加入含0.1 mmol/L非必需氨基酸、2 mmol/L L-谷酰胺、0.1 mmol/L二羟基丙硫醇、15%胎牛血清、1 000 U/mL白血病抑制因子的IMDM培养液。3 d后采用&悬滴法&使细胞在不含白血病抑制因子的上述IMDM培养液中形成胚胎体，6 d后胰酶消化得到胚胎干细胞，浓度调整为（3~4）×109 L-1，与Matrigel？

A single zircon U-Pb age of 3605±43 Ma from the oldest granite-gneiss was reported in Aketashtage, eastern Altyn Tagh, which is located on the southeastern margin of the Tarim Platform.

在阿尔金山阿克塔什塔格曾测得3605±43 Ma的单颗粒锆石U-Pb年龄数据，获得了古老地壳存在的同位素年代学信息。

On this proton-density-weighted image, the high signal corresponding to edema respects the gray-white junction, but tends to spare the "u"-fibers.

在质子密度像上，水肿高信号已涉及到灰白质联合，但有向&u&纤维扩展的趋向。

They are supergene minerals occurring in oxidized zones of uranium deposits and assuming green-yellow colors. This kind of minerals can be used as one of the mineral indicators in search for uranium deposits. They are mainly composed of ~(3-) and ~(2+), in which As and U are known as poisonous and harmful elements causing environmental pollution.

铀酰砷酸盐矿物是主要产出于铀矿床氧化带中比较特征的黄绿色表生矿物，是寻找原生铀矿床的重要矿物学标志，化学组成主要是[AsO4]^3-和[UO2]^2 ，其中As和U均是对环境造成极大危害的有毒或放射性有害元素。
