The Structure is similar to"Bird Cage", which can be used in higher resonance frequency.

其结构类似于"鸟笼"式，以在较高共振频率时使用。

Through the noise analysis between circular oscillators composed of general differential amplifer element and of capacitive coupling differential amplifier element, it is found that the later,due to its band-pass and dynatron characteristics,provides a better anti-noise performance,which can be used in VCO circuits having a high requirement on frequency stability.

通过对采用由普通差分放大器单元和容性耦合差分放大器单元构成的环行振荡器的噪声分析得出，由容性耦合差分放大器单元构成的环行振荡器，因其带通特性和负阻特性而具有较好的抗噪声能力，可用于对频率稳定度有较高要求的VCO等电路中。

For products such as laptops and monitors customized metal antennas can be integrated into the casework, although care must be taken to minimize signal losses due to cables and connectors, particularly at the higher frequencies.

对于产品，如笔记本电脑和显示器定制的金属天线可以融入个案，但必须注意尽量减少信号的损失由于电缆和连接器，特别是在更高的频率。

Analis presented in our 85 survey locations that were distributed in all counties on the Taiwan excluded the Taitung county, Hualien county, green island and orchid island. The altitude of P. analis habitats ranged from plain to the 400 m. The eleven types of habitats included bamboo plantation, windbreaks, orchard, dry riverbed, grassland, tea plantation, broadleaf forest, vegetable, paddy field, sugarcane field, and Arecae catechu showed the high diversity. The grassland was found in the highest ratio among 34 habitats and followed by the dry riverbed, which was found eleven sites.

经调查此虫在台湾分布情形，结果发现有栖地85处，台东县、花莲县、兰屿、绿岛除外，其余各县市皆有分布，从平原至海拔400公尺间；幼虫栖地类型有竹林、防风林、果园、河床、草地、茶园、阔叶树林、菜园、农田、蔗田及槟榔园等11型，显示其多样性高，其中草地型34处出现的频率最高，河床型13处次之。
