Using matlab, the acoustic reflected pressure from a submerged elastic/piezoelectric bi-laminated plate is calculated.

本文采用matlab 软件，对水下弹性/压电双层板的声波反射进行了数值研究。

The strings act as part of the acoustic reflection when under the canopy, and then become acoustically transparent over the rest of the space.

作为声反射时的天篷下采取行动的一部分字符串，然后成为透明声学在剩余的空间。

But when this light beam was a point of view into a small acute angle, the light energy will be returned only on the surface of reflection, but merely illuminate the thin cell wall.

但是当这束光被折成一个角度很小的锐角时，光的能量就会仅从细胞表面反射回来，而仅仅照亮薄薄的细胞外壁。

As the system that upgrades ceaselessly and applied demand, collateral technology cannot all sorts of evasive problems, if signal ends restriction, the reflex of cable and connector, signal twist is mixed string of sound, and the problem such as equipment addressability becomes the obstacle that raises data to transmit function, also got restrict on efficiency and augment latent capacity.

随着不断升级的系统和应用需求，并行技术无法回避的各种新问题，如信号终止限制，电缆和连接器的反射，信号扭曲和串音，以及设备寻址能力等新问题都成为提高数据传输性能的障碍，在效能和扩充潜力上也受到了限制。

This problem has been overcome with an iterative inversion that uses an imaging operator and its adjoint along with a regularization operator.;The imaging operator used in the inversion process is a linear operator relating reflectivities to data.

这个问题已经克服了迭代反演，使用成像算子及其伴随连同正规化运营商。；的影像操作中使用的反演过程是一个线性算子有关的反射率的数据。

The optical recording behavior of 1-Azo nickel chelate was performed by adynamic optical recording tester utilizing signals of central frequency 500kHz and 1 ×recording speed under irradiation of 780 nm semiconductor laser. When the writingpower is 7-8 mW, the CNR reaches 45 dB.

采用光盘动态测试仪测定了具有支持盘片、以偶氮染料1-Azo镍螯合物为记录层、反射层的三层结构盘片的光记录性能，用780 nm半导体激光，中心频率500 kHz，1倍速转速，写入频率为7-8 mW时，载噪比为45 dB。

Based on the analysis, a new AFC system based on self-optimizing control is proposed with the experience of experts.

本文中简要分析锁相型自动频率控制系统的基本原理及其在实际应用当中遇到的问题，进而提出了一种新型的基于反射波极小值的AFC系统，并对其原理进行了深入的剖析。

Figure 41-7 shows two plates of glass separated by a wedge of air; we want to consider interference between the two light waves reflected from the surfaces adjacent to the air wedge, as shown.

如图41-7显示了两块被空气劈尖分开的玻璃盘，我们考虑发生在楔形空气两表面的反射光线的干涉，如图显示。

If the observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
