查询词典 angle of altitude

Aiming at improvement of attack precision and reduction of target miss distance, different guidance and control laws are proposed and analyzed, the influences of many different kind of conditions to attack precision such as initial flying altitude, airspeed, flight path angle, external disturbance and target movement are investigated. Beneficial to theoretical significance and inspiring for engineering practice results are obtained.

紧紧围绕提高末制导精度、减小脱靶量这一研究目的，对不同的末制导控制方式、不同的末制导导引律、不同的末制导进入条件、不同的外部干扰、不同的目标特性等都进行了深入的研究、分析和探讨，并给出具有一定理论意义和丰富的工程实际应用价值的结论。

Results show that amplitude of displacement excited by vertical incidence wave is larger than that excited by inclined incidence wave and not influenced greatly by the incidence angle. In vertical incidence, amplitudes of displacement of two points at the same altitude along each cavern are basically identical and maximum relative displacement occurs between top and bottom point of the cavern. While in the case of inclined incidence, displacement amplitude on sides meeting the wave is larger than that on leed sides, and maximum relative displacement occurs on left skewback and bottom of the cavern.

结果表明，位移幅值受入射角度的影响不敏感，竖直入射比斜入射情况要大；竖直入射时，各洞室两侧同一高程处的位移幅值基本相同，相对位移差最大部位为洞顶与洞底，而斜入射时迎波面比背波面一侧位移大，且相对位移差最大部位为洞室迎波面的左拱座与洞底。

At present, the company focused on business:(1) production and operation of HUMO-O-level vehicle and HUMO-O Universal Instruments and other automotive products (modified in order to meet user requirements, the company also operates fully fit Huatai Yoshida, Jiangling Landwind, Jianghuai Switzerland Liu steam and wind, and other popular models of vehicles converted General Instrument), these products can show elevation, relative altitude, atmospheric pressure, slope, tilt angle and direction, and other functions,(2) to provide professional auto parts such as product design and mold-related seizure A, fixture design and processing,(3) The Acting distribution of various radar detectors, satellite-safe driving, vehicle-level / balance-(such as the eyes of the fire radar detectors, Iger satellite for safe driving, TOTOCA car With Level, Type-R car for balance) and so on.

目前，公司重点业务：（1）生产经营HUMO-O车用水平仪和HUMO-O汽车通用仪表等产品（为了满足用户改装要求，公司还经营完全适配华泰吉田、江铃陆风、江淮瑞风和柳汽风行等车型改装的汽车通用仪表），这些产品能显示海拔、相对海拔、大气压、坡度、倾斜角和方向等功能；（2）专业提供汽车配件等产品设计和相关模具、检具、夹具的设计与加工；（3）代理经销各种雷达侦测器、卫星安全驾驶仪、车用水平仪/平衡仪（比如金火眼雷达侦测器、伊格尔卫星安全驾驶仪、TOTOCA车用水平仪、Type-R车用平衡仪）等等。

The problem of the altitude measurement in VHF radar is the low elevation angle estimation.

米波雷达的测高问题实质是低仰角的估计问题。

Compared the voltage negative feedback wire-feeding speed regulation system supported by current positive feedback with the rotational speed negative feedback regulation system, the equivalent condition of the two systems is obtained. Then, a wire-feeding speed regulation circuit for the CO_2 welding machine is designed based on TL494 chip, which has the self-protective function under the condition of current overloading.
