Known as the SENSIMED Triggerfish, the solution is based on a "smart" contact lens that uses a tiny embedded strain gauge to monitor the curvature of the eye over a period of, typically, 24 hours, providing valuable disease management data that is not currently obtainable using conventional ophthalmic equipment.

意法半导体宣布，瑞士Sensimed AG设计的突破性平台研制无线MEMS传感器，这款内建于隐形眼镜的独特传感器，可以作为该平台附加数据读取电子系统的换能器、天线以及机械支撑组件。

However,this may causes analysis errors for ultra-high frequency transducers.

但这种处理方法在分析超高频换能器时会带来较大的分析误差。

The wave front of the ultrasonic wave can be changed by using the sound lens.

目前 ，增大超声波在岩层中传播距离的方法是增大超声换能器的功率。

The result of experiment proves that the matching layer transducer can use in arrays in effect, its directive parameter is not unconventionality change, and its power function is all right.

实验证明匹配层换能器能够有效的进行布阵，布阵后的指向性参数没有异常变化，功率线性良好等。

After treatment with the above hormones, the rats were established anesthesia with urethan (1g/kg, i. p.); polyethylene catheters were inserted into the external jugular vein and the common carotid artery for drug administration, and then blood pressure was recorded. The arterial catheter was connected to a pressure transducer, and the blood pressure was displayed on the channel of BL-310 Experimental System of Biological Function through IBM computer. We assessed the changes of resting arterial blood pressure, the pressor responses of angiotensin Ⅱ(Ang Ⅱ, 0.01mg/kg), noradrenaline (NA, 0.01mg/kg) and adrenaline (Adr, 0.016mg/kg). The depressor responses of Ach (0.006mg/kg) and carotid sinus baroreflex were also discussed after treatment with the hormones in OVX rats.

用不同雌激素处理21天后，将动物用25％的氨基甲酸乙酯腹腔麻醉（1g／kg），做颈总动脉插管，通过压力换能器，将血压变化输入计算机，通过BL-310智能型生物信号显示与处理系统的压力测定模块，观察去势鼠及不同雌激素替代治疗大鼠静脉注射血管紧张素Ⅱ（AngⅡ，0.01mg／kg）、去甲肾上腺素（NA，0.01mg／kg）、肾上腺素（Adr，0.016mg／kg）的升压反应以及乙酰胆碱（Ach，0.006mg／kg）的降压反应和压力感受性反射的变化。

The liquid density sensors presented in this project are dependent on the Surface Acoustic Wave technics in the fabrication process. Considering the maturity of SAW technics and the easiness of high frequency BAW generation with the IDTs, it is convenient for sensors miniaturization.

本项研究工作提出的微量液体密度传感器在制作上仅需采用成熟的声表面波工艺即可，实现起来比较容易，叉指换能器容易激发较高频率的体声波，便于传感器小型化。

Place the die on model base, adjust the cross board and dragging board of transducer to make the steer needle insert into the model pole, then put on abrasive, open up the switch of ultrasonic power and model base circumrotation.

模具放在模座上，调节十字脱板及换能器上下拖板，使钢针插入模孔内，然后放上磨料，打开超声波电源开关和模座旋转开关。

In chapter two, we introduce the theory of SAW, and the basic constructure and operation principle of SAW-IDT.

第二章，介绍了SAW原理及其基本性质；给出了SAW叉指换能器的基本组成与主要参数等。

In this case, the power is supplied by piezoelectric flexural transducers.

在这个例子中，压电式受弯换能器提供电能。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
