查询词典 depth charge

A boot-type jet trenching system is adopted which is towed by the supporting ship. It is mainly used for trenching hard sandy clay at the shoal area with water depth 0.8m to 30m. Diameter of the cable to be buried is up to 150mm, and the burying depth more than 2m. This system has advantages of simple structure, high burying speed and great trenching depth.

该系统采取滑靴型式的喷冲挖沟方式，理缆机由母船拖曳前进，主要用於水深在0.8~30m的滩海，底质为硬砂土和红胶泥层，埋设直径小於150mm的电缆，埋设深度大於等於2m。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。

From the angel of so-called political"essence"and"rule", the Cainozoic Era writers have not provided much depth for us. But from the angel of life politics, we can find"depth"in other dimension. If we ignore this"depth"and temporize it with excuse of"flatness", our comment will be at risk of invalidity.

假如从所谓历史的&本质&和&规律&的角度看，新生代小说确实没有为我们提供多少&深度&，但仅仅从生活政治这一新的角度着眼，就已经可以看出它们在另外的维度上所拥有的&深度&。

Depth charge: or depth bomb; Weapon used by ships or aircraft to attack submerged submarines.

深水炸弹：由水面上船只或飞机攻击水底潜艇之武器。

Depth charge; depth bomb

The cycling life of Ni 〓 was measured with powder microelectrode by cyclic voltammetry for the first time. Results show that the depth of charge is up to 75%, and the depth of discharge almost reached to 100% when the scanning range is controlled within 0～ 0.6V vs.

对Ni〓粉末微电极的测试表明，当控制三角波扫描范围0～0.6V、扫描速度20mV/s时，每次循环电极的充电率可达到75%，而放电率接近100%，完成一个周期仅需要1分钟，因此极大地缩短了测试时间。

The available tunneling depth of channel carriers is dependent of frequency. Hence traps density in opposition to dielectric depth is extracted by charge pumping current and frequency.

通道电子能穿隧的深度会随著不同操作频率而改变，因此可由电荷帮浦电流对应到频率便能得知在闸极介电层中不同深度的缺陷密度。

Additionally, the vessel is also armed with two dual-37mm AAA guns, four dual-12.7mm machine guns, and two BMB-1 depth charge projectors (with 10 depth charges).

另外，也装备二座双-37毫米AAA炮，四挺双-12.7毫米机枪和二具BMB-1深水炸弹投放器（连同10枚深水炸弹）。

In this paper, the size and structure of the uniplanar scattering-field capacitance sensors are optimally designed by simulation and experiment for test depth and testing feature with guard electrode for improving the anti-disturbance capability. A new uniplanar scattering-filed capacitance sensor for measuring water in building inclosure is designed based on improved charge/discharge capacitance measuring circuits. This kind of sensor has wide test depth and high sensitivity.

针对围护结构含水率测试深度的要求和测试特点，本文通过仿真和实验，对同面电容传感器探头的结构尺寸进行了优化设计，并采取了保护电极以提高其抗干扰能力；运用改进的充放电电容检测电路，设计出一种测量围护结构含水率的新型同面散射场式电容传感器，该传感器具有宽范围的测试深度和较高的测试灵敏度。
