脱落酸和赤霉素是两种重要的植物激素，脱落酸和赤霉素之间的相互关系是调节多种生理活动的关键因素。

The fruit abscission mechanism of plant is generally considered as one of the key factors maintaining system stability.

植物果实的脱落机制普遍被认为是维持系统稳定的关键因素之一。

Say for example, the search personnel that has 5% about is Absinthe mosaic Absinth, the word that adds this misspelling so serves as auxiliary key word (the word that spells correctly in order to complement) perhaps be more be helpful for website promotion.

比方说，约有5%的搜索人员把absinthe拼成absinth，所以添加这个拼错的单词作为辅助关键字也许是更有利于网站推广。

Say for example, the search personnel that has 5% about is Absinthe mosaic Absinth, the word that adds this misspelling so serves as auxiliary key word (the word that spells correctly in order to complement) perhaps be advisability lift.

比方说，约有5%的搜索人员把absinthe拼成absinth，所以添加这个拼错的单词作为辅助关键字也许是明智之举。

The key to feature extraction is to select the optimal feature combination from all the features. In this study, the optimal color feature combination,{/G,(R+4G+B)/6, H variance, S variance}, is selected using genetic neural network at first. Then the main texture features including the mean, variance, energy and entropy of the cooccurrence matrix, the secondary texture features including the maximum frequency number, absolute uniform, inertia and importance of the co-occurrence matrix are extracted.

在此基础上，提出适合多阈值和小目标图像分割的免疫遗传图像分割方法，该方法借鉴了生物免疫系统自调节、抗原识别和记忆功能，并结合了遗传算法对图像进行自适应区域的阈值分割，改善了遗传算法优化复杂问题时存在收敛速度慢和易陷于局部最优的不足，克服了传统阈值分割方法对目标大小的限制，是一种新型的有效的图像分割方法。

New US research indicates that the absolute humidity, which measures the amount of water present in the air, is the key to reducing the spread of flu.

美国最新研究表明，空气绝对湿度与流感病毒的传播有密切关系。

In the second chapter, we investigate propagations of desynchronous disturbances in synchronized chaotic one-way coupled map lattices. It is well known that spatiotemporally chaotic systems with large gradient couplings may show convective instability under the absolute stability condition of chaos synchronization. This convective instability is the key reason for the effective propagation of control signals.

时空混沌在不同的耦合系数情况下会表现出不同的动力学行为，用驱动实现具有强梯度耦合系数的时空混沌同步时，会观察到在绝对稳定条件下被驱动系统表现出对流不稳定性，这种对流不稳定性是在单个信号驱动下实现混沌同步的关键原因。

However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT.

对於高电流的影响，磁旋行波放大器将有可能引发绝对不稳定、磁旋返波振荡(gyrotron backward oscillation；gyro-BWO)及反射振荡，造成模式竞争而抑制原先操作模式的放大波，进而影响其输出功率、增益及效率。

However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT, therefore physical origins of spontaneous oscillations in the gyro-TWT are analyzed and characterized.

然而受限於操作高电流，磁旋行波放大器可能引发绝对不稳定性、磁旋返波振荡(gyrotron backward oscillation；gyro-BWO)及反射振荡，造成模式竞争而抑制原先操作模式的放大波，进而影响其输出功率、增益及效率。
