瓶颈

In this dissertation, a three-phase nonequilibrium model for packed column distillations is developed.

在三相共沸精馏过程建模仿真和优化计算中，由于两个液相可能同时出现，判断液相稳定性问题已成为了一个三相精馏过程计算的瓶颈问题，这也是本文的研究重点之一。

Systemic researching of these phenomena, finding the principle of them and decreasing the effections of the nonuniformly sampling with post data processing, will promote the development of the time-interleaved ADC system.

随着数字信号处理技术的发展，ADC的采样速率和精度成为各种电子系统的瓶颈，提高ADC的采样速率和精度成为学术界和仪器厂商的首要目标。

To transmit high speed pulse, limiting amplifier must have enough bandwidth. So a research about CMOS broadband amplifier, supported by Octillion Communications Inc.

为了在接收机前端CMOS芯片中传输极其高速的数据如OC—96和OC—192标准，需要克服的瓶颈之一是获得高速的限幅放大器。

Therefore,t he programming response which is not an independent processing stage d oes not constitute a bottleneck.

因此，反应组织不是独立的加工阶段，故它不具有瓶颈性质。

By the application server of MS, CATV operators can access the database server to independently manage the users. The network bottleneck, performance descent brought by the overabundant connection of database and load balance of business process is solved effectively, and the response time of database and system security is improved.

各有线电视网络运营商可通过管理系统的应用服务器，访问数据库服务器，达到了用户的独立管理，有效地解决了网络瓶颈和数据库连接数量过多造成的数据库性能下降的问题，实现业务处理负载均衡，提高了数据库响应速度，同时使系统的安全性得到提高。

The pharmic difference of air-dried Chinese herbs on the market is the bottleneck for Chinese medicine standardization, which arises from relative lag assay.

市场中药干品的药性差异一直是影响中药标准化的瓶颈，而检测技术相对落后是导致这一现象的主要原因。

Thus, the focus of our study is to design near-infrared fluorescent probe with good selectivity, high sensitivity, good photostability and working within the acidic pH range.

另外，用于检测酸性器官内的尤其是理想的pH探针几乎没有，这被认为是细胞生物学及医学发展的瓶颈。

It was seen that the condition of capital scarcity was a very important"bottleneck"which restricted Chinese economical develop, because the unbalance proportion capital formation process had led to huge gap between towns and countries during the time of prereform. After reform, more industries had conglomerated into inshore regions than inland regions attributed to the imbalance distribution of capital. The gaps between towns and countries and among regions have led to labor migration in order to get jobs.

资本是制约我国经济发展的一个很重要的&瓶颈&，在改革开放之前，资本形成在导致巨大的城乡差异过程中扮演了关键性角色；改革开放后，资本在我国地区间的分布不平衡导致了沿海地区的产业集聚和内陆与沿海之间地区差距的进一步形成；城乡差异和地区差距导致我国劳动力的大量而持续的转移。

The application of psychrophilic methanogens in anaerobic bio-treatment process could essentially break through the bottle-neck of anaerobic technology at lower temperature,greatly extend the application fields of anaerobic technology,and reduce the operational cost of wastewater treatment.

利用嗜冷产甲烷菌实现低温厌氧生物处理过程，可从本质上突破低温厌氧工艺的技术瓶颈，进而大大拓展厌氧生物处理技术的应用范围并降低废水处理的成本。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
