Usually production tests of DLD are performed between 1 and 10 microwatts and then at 1Mw and again at a low load.

通常生产中测试DLD是用1~10mV测试后再用1mV测试，发生的阻抗变化可作为测试的标准。

Usually production tests of DLD are performed between 1 and 10 microwatts and then at 1 Mw and again at a low load.The relative change in resistance is then used as the test criterion.

DLD。通常生产中测试DLD是用1～lOmV测试后再用lmV测试，发生的阻抗变化可作为测试的标准。

These results suggest that the prescription reciped based on the theory of the correlation between spleen-stomach and mentality can effectively hold back the epileptogenesis. The antiepileptic mechanism of the prescription may relate with reducing the release of monoamines; regulating the level of cAMP and cGMP and diminishing gene and protein expression of c-fos、c-jun.

本文研究结果提示，根据脾胃与神志相关理论，以调理脾胃为主旨组成的复方能有效阻抗PTZ点燃大鼠EP发作；其抗痫机理可能与减少单胺类神经递质的释放、调节cAMP、cGMP水平，进而削弱c-fos、c-jun基因及蛋白的表达有关。

In series/parallel mode, you can wire 4 woofers to a single amp, for example, and still maintain a compatible impedance.

在series/parallel 方式下，您能架线4 台低音扬声器对一安培，例如，和仍然维护兼容阻抗。

This enables you to combine the AERMD-3 with our high-end woofers and passive crossovers without having a volume correction between your drivers.

这样可以更好的和我们的低音炮单元的阻抗相匹配来制作被动式二分频音箱。

Parallel wiring provides for maximum amplifier output, while series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance.

平行的接线提供最大放大器产品，当系列接线让您配置多台低音扬声器对一个放大器在可接受的阻抗。

Based on the characteristics of varistor, the influence of the different impedance values between the protective devices is discussed.

结合浪涌保护器的电压—电流特性，利用推导出的公式研究由压敏电阻组成的多级保护系统，分析两保护器之间的阻抗变化对暂态过电压在两级保护器上分配的影响。

So we should consider choosing the way to design it according to a variety of factors.A NLTL frequency tripler in Ka-band are designed by loading eleven varactors in a high impedance microstrip line in the thesis.

本文利用高阻抗微带线加载11个变容二极管实现了非线性传输线八毫米三倍频器，该倍频器的缺点就是管子太多，不利于小型化。

The microstructures of composite membranes were studied by XRD and SEM. The thermal stabilities, methanol permeabilities and proton conductivities were investigated. Water uptakes and dimensional stabilities were also studied. The results indicate that amorphous zirconium phosphates are formed in the composite membrane, and have a good combination with the organic phase.

采用扫描电镜观察复合膜的断面形貌；采用热重分析仪研究复合膜的热稳定性；采用气相色谱测量并计算了复合膜的阻醇性；采用交流阻抗法测量复合膜的质子传导率；同时还研究复合膜的吸水率、尺寸稳定性。

Furthermore, you may put the SN74HC595N output pins into TRI-STATE to achieve a high impedance state.

此外，您可投入三态输出引脚的SN74HC595N实现高阻抗状态。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
