您要查找的是不是:
- effective acoustic pressure 有效声压
- The output signal from the interferometer is proportional to the acoustic pressure in water. 输出的信号直接正比于液体中的声压。
- Experiments indicate that our contrast technique is not sensitive to contrast dose, flow rate, acoustic pressure. 证明本文提出的造影成像方案对声压、流速、造影剂浓度在一定范围内不敏感。
- If necessary to avoid, but also the deployment of cabinets, or in bathrooms and other rooms for secondary segregation, and at the same time take effective acoustic, Jianzhen. 如果因故难以避开,也要布置壁柜,或以卫生间等次要房间进行分隔,并同时采取有效的隔声、减振措施。
- In a word, whether in estimator performance of DOA or detector performance of signal, vector array is excel to general acoustic pressure array. 综上所述,无论是目标方位估计性能,还是信号检测性能,矢量阵都优于常规声压阵。
- The acoustic pressure and acoustic power of the whole structure are obtained by superposing those of each infinitesimal element. 以每个微元为一单位,分别计算声压和声功率之后叠加起来,即得整个结构的声辐射。
- On the contrary, the collapse of bubble will become more violent with higher acoustic pressure, but overhigh pressure will make it never happen. 提高声场声压 会加剧气泡崩塌程度,但过高的声压又不能使微气泡崩塌;
- Methods A hydrophone was used as energy converting equipment to collect wave of acoustic pressure in the field of ultrasound. 方法:采用水听器作为换能器,通过采集超声信号在空间声场内一点的声压波形。
- In circumstances like varying SNR, fluctuating acoustic pressure and excursive frequency, numerical simulation shows that the detection system works well. 在信噪比变化、声压起伏、线谱漂移等情况下,仿真结果表明双稳态随机共振系统都能较好地工作。
- By measuring the acoustic pressure at two points along the tube, the standing wave sound field in the resonator could be separated into incident and reflected components. 在该方法中,只要测量沿程两点的声压,便可将管内平面驻波声场分解为入射波和反射波两种分量。
- The Helmholtz integral formula shows that the acoustic pressure in an enclosed space can be treated as superimpose result of contribution of all boundary elements that act as sound sources. 由边界积分公式表明 ,封闭区域内某一点的声压可以看作由边界面上次级声源发出的声波在该点贡献的叠加。
- That's rather an effective use of color. 这种使用颜色的手法效果相当好。
- The arrangement is also effective acoustically, because the opening gives to the ceiling surface a naturally convex shape that scatters sound toward the periphery and reduces echoes. 同时在声学上也是有效的。因为开口赋予天花表面一个自然的凸圆面形状,这就将声音朝四周分散,有效地降低了反射波。
- decibels above reference acoustic pressure 超过准基声压的分贝数
- In the short term, the medicine may not be very effective. 从眼前来看,这药可能疗效不是很大。
- acoustic pressure and particle velocity 声压和质点振速
- Reconstruction of acoustic pressure fields 声场重构
- The radiated acoustic pressures are obtained by means of an expansion of independent functions generated by Gram - Schmidt orthonormalization using a group of spheroidal wave functions. 使用长旋转椭球函数得到一组独立函数,把声场中的声压表示为独立函数的线形叠加。
- When does the new system become effective? 新制度何时生效?
- The fear of ridicule is a very effective sanction. 人们不做违法乱纪的事,其中一个重要因素就是怕人耻笑。
