抑制地

Firstly, the control of reentry phase and the model of RCS jets are presented. Then the flight control system is divided into two subsystems based on the time-scale separation principle. The fast states subsystem corresponds to the three body-axis angular rates, the slow states subsystem controls the angle-of-attack, sideslip angle and the rate of the bank angle about the velocity vector. Lastly, the proportional-plus-integral feedback is designed to increase the system robustness.

首先，分析了SRLV再入段的数学模型，并给出了反作用推力控制系统的控制模型；其次，将非线性动态逆方法与时标分离原则相结合，考虑飞行器姿态控制系统的外环角回路的慢变特性和内环角速度回路的快变特性，独立设计了两个回路的控制律；最后，为了增强系统的鲁棒性，分别在两个回路中引入了比例－积分反馈，有效地抑制了干扰力、力矩和非线性对消带来的逆误差。

The results show that it can effectively control the penetration of cobalt and improve the quality of diamond coating and improve tool's life by 10 times when the substrate is pretreated in the condition of acid leaching in dilute HCl for 15 min and then soaking in dilute ammonia solution for 10 min.

结果表明，在1∶3的稀盐酸中酸洗15 min后用氨水浸泡10 min的基片处理方法能有效地抑制金属钴的溢出，从而提高金刚石涂层的质量，并且使刀具使用寿命提高10倍以上。

Objective: To explore the difference of clinical features and biochemical indices of hypercortisolism among male and female patients with Cushing's disease. Methods: Eighty-one patients (56 females and 25 males)with CD were selected.

手术确诊的库欣病患者81例，根据性别分为男性组25例，女性组56例，比较2组临床症状、影像学检查结果，血、尿皮质醇，血促肾上腺皮质激素，小剂量(1 mg和/或2 mg)及大剂量(8 mg)地塞米松抑制试验的结果。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
