不稳定性

Nowadays, adaptive rate control is the basic and significant technique of video multicast systems in the Internet. These adaptation approaches are all designed based on the best-effort service that today's Internet can provide, they present two drawbacks—unsteadiness of video receiving quality and no consideration of intersession fairness.

当前，自适应速率控制是因特网中视频组播系统采用的一种最基本和最重要的技术，但现有的自适应机制都是基于因特网提供的尽力而为服务来设计的，它们具有如下两个缺陷，即视频接收质量的不稳定性和无法实现会话间资源共享的公平性。

Downward continuation is an important operation in potential field data processing and inversion, but its instability problem influences its application in many processing and inversion techniques.

位场向下延拓是位场数据处理和反演中的重要运算，但是它的不稳定性影响了它在许多处理和反演方法技术中的应用。

This state of affairs not only leads to the unsteadiness of the development of the Chinese poems in the 20th century,but also displays the spiritual predicament faced by the Chinese people in the process of seeking modernization,in other words,the hesitation and the irresolution in the chosing of the individual value and the group value.

这一状况造成了20世纪中国诗歌发展的不稳定性，也反映了中国人在追求现代化的过程中所面临的精神困境，即在个体价值和群体价值选择中的徬徨和犹豫。20世纪中国诗歌语言观念的演变带给我们的启示是：既要坚持诗歌的文化批判立场，又要保持其作为艺术的独立性，就是要在语言的自我指涉和外在指涉之间找到一种能使诗成为艺术的平衡点，使诗能通过展现其自身的意义，同时又超越其语言自身的意义进入到新的意义的生产语境，进而参与到对现实世界的想象性建构过程中去。

It also covers two-fluid hydrodynamic plasma models, wave propagation in a magnetic field, kinetic theory, Vlasov plasma model, electron plasma waves and Landau damping, ion-acoustic waves, and streaming instabilities.

它也涵盖双流体的流体动力学的等离子体模型、磁场内的波传播现象、动力理论、Vlasov等离子体模型、等离子体波、蓝道阻尼、离子声波和串流不稳定性。

In the past century, people have devoted themselves to the worldwide problem——cancer, which does harm to people's health. Of late years, much research has been found that spindle checkpoint, which is a highly conservative mitotic watch system in the kinetochore of chromosome, has close correlations with chromosome instability and tumorigenesis.

近一个多世纪，人们一直在致力于攻克癌症这个危害全球健康的难题，近年来，大量的研究结果表明位于染色体动点上的一个高度保守的有丝分裂监督系统——纺锤体检验点，与染色体不稳定性及肿瘤的发生密切相关。

High expression of FAT10 can decrease the molecules positioning on the kinetochore MAD2 and then increase chromosomal instability in the early and mid-term cell cycle.

在细胞周期的前期和中期中，高表达FAT10减少定位在动粒上的MAD2分子，从而增加染色体的不稳定性。

Due to the potential lability of vinyl triflates, the availability of mild reaction conditions can be critical for efficient coupling of sensitive substrates.

鉴于乙烯基三氟甲磺酸酯潜在的不稳定性，保证反应条件温和对于敏感底物进行有效的交叉偶联反应而言，是至关重要的。

Nurses' work environment lability is closely related to somatization discomfort; likelihood of job unhealthy change and significance of unemployment are important factors influencing nurses' somatization discomfort.

护士工作环境的不稳定性与躯体化不适密切相关；工作不良改变的可能性和失去某一工作特性的重要性等因素是影响护士躯体化不适的重要因素。

Loiseau left the Ecole after a year of studies and enrolled at the studio of Fernand Quignon, a landscapist living in Paris.

这两种观察方法在这里是彼此对立的，而不是混合的；由此而产生了构图的不稳定性。

In this blasting, the bench with 3-5m length is always left at work face, simultaneously, the smooth blasting is implemented to reduce strength of explosion vibration and surround rock instability.

在采用微台阶的同时，采用光面爆破技术以降低爆破地震动强度，以尽量降低围岩的不稳定性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
