自发的

Therefore, the multi-stage interaction structures with losses and severed structure were more stability for absolute instability and gyrotron backward oscillations. This study presents a nonlinear analysis of typical oscillations, including absolute instability, gyrotron backward oscillation and reflective oscillation. The multi-stage gyro-TWT seem to increase effectively the start-oscillation currents of the absolute instability, gyro-BWO, and reflection oscillation.

所以在本研究分析中，藉由了解磁旋行波放大器中的自发振荡物理原因及特性，将有助於高功率放大器的设计，并且引用非线性程式进行磁旋行波放大器稳定分析，并且采用兼具隔离管及散布式损耗结构的磁旋行波放大器，同时提升绝对不稳定、磁旋返波振荡及反射振荡的稳定性能有效提升磁旋行波放大器输出功率和频宽。

Something that is ad-lib is spontaneous and improvised and therefore not part of a prepared script or score

ad-lib 的事物是自发产生的和即兴而作的，因而不是预先准备的手稿或记录的部分

He writes extremely musical music, of which the sound is fastidiously calculated and yet agreeably spontaneous and imaginative.

他创作很极端的配乐音乐，这种音乐的声音是经严格计算的，然而又是自发产生的，并且极富想象力，听起来很舒服。

The heavy elements in the theory of spontaneous metamorphosis immediate sensation around the world ;(4) is proposed to estimate the Earth's radiation age;(5) from the charge-mass ratio α which is derived helium ions;(6) from the scattering of α Bighorn recognized atomic mass concentrated in a radius of 10-12 meters in the nuclear, on positively charged core surrounded by negatively charged electrons;(7) with natural α-particles from the nitrogen nuclei in the outgoing protons, this is the first time human beings to change the chemical elements of artificial nuclear reactions;(8) predicted that heavy hydrogen and neutron sub-existence .

这一重元素自发蜕变理论立即轰动全世界；（4）提出用放射性估算地球年龄；（5）从α的荷质比得出它是氦离子；（6）从α大角散射认识到原子质量集中在半径为10－12米的核上，核带正电，周围是带负电的电子；（7）用天然α粒子从氮原子核中打出质子，这是人类第一次实现改变化学元素的人工核反应；（8）预言重氢子和中子存在。

The phenomenon was first reported in 1896 by Henri Becquerel for a uranium salt, and it was soon found that all uranium compounds are radioactive due to the uranium's radioactivity.

放射性：某些类的物质自发发射辐射的特性。1896年贝克勒耳第一个报告在铀盐中发现了这一现象，不久发现由于铀有放射性，所以所有的铀化合物都是放射性的。

"Radioactivity: Property exhibited by certain types of matter of emit ting radiation spontaneously. The phenomenon was first reported in 1896 by Henri Becquerel for a uranium salt, and it was soon found that all uranium compounds are radioactive due to the uranium's radioactivity."

放射性：某些类的物质自发发射辐射的特性。1896年贝克勒耳第一个报告在铀盐中发现了这一现象，不久发现由于铀有放射性，所以所有的铀化合物都是放射性的。

Sometimes it's snobbery, a reflexive sneer at anything popular with everyone from indie kids to housewives. Sometimes it's chippy resentment at their middle classness, their university education.

有时候是因为充内行，自发地嘲讽一切受大众欢迎的事物；有时候出于对中产阶级、大学教育的怨恨；有时候是因为老掉牙的男子气概、认为摇滚就是"烂醉＋扁人"的陈腐念头。

Self-heating effect in LDMOS is also investigated by using the special metal contact structure and a fast transient circuit.

接著，我们利用特殊的金属接触电极以及快速的暂态电路来研究LDMOS的自发热效应(self-heating effect)。

Otherwise, rigidly or narrowly emphasizing some certain "standard" will inevitably "spoil things through excessive enthusiasm", which might bring damages to the corporations along with the embedded community, which both could have developed with self-generation and inter-adaptation.

否则，僵化、片面地强调某种&标准&，势必会出现&拔苗助长&的效果，可能导致一些原来有本地社会基础并能够自发成长的企业及其所嵌入的社会遭受破坏。

The mechanism of this dissolution was attributed to Ostwald ripening.

讨论了铁氧化物自发溶解的原因，认为空心碳纳米棒的形成是由Ostwald熟化现象造成的。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
