Also choose elevation angles as positive above the boresight axis and negative below, and choose azimuth angles as positive in a clockwise direction and negative in a counterclockwise direction.

同时规定波束仰角在视轴线以上为正，以下为负，方位角以顺时针方向为正，逆时针方向为负。

Acting upon this hint, Monsieur Val opened the outer door of a stately suite of apartments, which included a lobby, paved with alternate diamonds of black and white marble, but of a dismal and cellarlike darkness; a saloon furnished with gloomy velvet draperies, and with a certain funereal splendour which is not peculiarly conducive to the elevation of the spirits; and a bed-chamber, containing a bed so wondrously made, as to appear to have no opening whatever in its coverings, unless the counterpane had been split open with a penknife.

根据这个暗示，瓦尔先生打开了一套富丽堂皇的房间的大门，其中包括一个走廊，（地上铺着黑白相间菱形大理石，可是廊内黑得阴沉沉的、象地窖一般；）一个雅致的会客室，（里边挂着暗淡的丝绒帷幕，呈现出一种丧葬的光采，那可并不对振奋心情特别有利；）一个卧室。（里边有张制作得很奇怪的床，看来盖在床上的东西都没有个出入的口子，除非用一柄小刀将床罩划破。

Accordingly, the elevation of the Huangshan at the late Cretaceous may have reached up to

据此，黄山在早白垩世的海拔高度可能达到2 693～

The first three largest number of missing teeth is as follows: maxillary first molar, maxillary second molar and mandibular first molar. The first three largest number of resident teeth is as follows: mandibular cuspid, mandibular bicuspid and maxillary cuspid. The cases without occusal relationship account for 19.51%; and the cases which need occlusal reconstruction or occlusal elevation account for 19.51% of all the cases, while food impaction exists in 21.84% cases.

结果：本组老年人平均缺失牙齿9.10颗，缺失最多的前3位牙齿是上颌第一磨牙、上颌第二磨牙和下颌第一磨牙；余留最多的前3位牙齿是下颌尖牙、下颌第一双尖牙和上颌尖牙。19.51%的病例颌骨间无咬合接触关系，19.51%的病例修复时需咬合重建或咬合抬高；21.84%的病例修复前存在食物嵌塞。

The instruments on the station awarded mirror after mirror site automatically will be treated in the form of three-dimensional coordinates of the data entered into an electronic tablet with radio transmission, and show points and Notes elevation.

测站上的仪器照准镜站反光镜后，自动将经处理的以三维坐标形式的数据，用无线电传输入电子平板，并展点和注记高程。

At present, the main approach for seismic data imaging is the prestack Kirchhoff time migration, however, violent variation of surface elevation makes the datum plane selection of prestack time migration very difficult.

目前该类地区地震勘探中主要的成像手段依然是Kirchhoff叠前时间偏移。但地表高程的剧烈变化使叠前时间偏移的基准面很难选择。

In addition, the low-temperature heat utilization in deaeration of desahed water and temperature elevation of deaerated water is explored on the basis of refinery system integration and optimization.
