查询词典 transmission loss

Magnetic transmission power with increasing temperature is a continuous decline in the curve, usually the work of extreme temperature in the magnet below the decline of its transmission capacity is reversible, but above the limit temperature is irreversible, that is, magnetic cooling After the loss of transmission capacity can no longer be resumed.

磁钢传递的功率随温度的升高是一条连续下降的曲线，通常，在磁钢工作极限温度以下，其传递能力的下降是可逆的，而在极限温度以上则是不可逆的，即磁钢冷却后，丧失的传递能力再也不能恢复。

At the same time, in the transmission system of construction machinery up-to-date, the power transferred by the transmission is improved greatly, while the gear friction is adopted in the transfer structure, so the heat loss will influence both the lubrication and cooling of the system, and the working intensity of the structure components. Therefore, the correction of the heat balance is necessary to the system.

同时，在现代工程机械的变速传动系统中，由于行星变速箱所传递的功率有了大幅的提高，但传递结构依然大量采用齿轮摩擦传动，其热损失不仅对系统的润滑和冷却有影响，而且对结构元件的工作强度也具有很大的影响，因此，也需要对该系统进行热平衡校核。

A standard expected value model for multi-objective multi-stage transmission planning is presented to realize the transmission optimal planning with the control of line overloading risks. In this model, a constraint of overloading risks is built with expected value and standard deviation of random line active power and two objectives are given as expected value of the average power loss and discount value of the investment cost. By modeling uncertain informations with probability theory, the probabilistic DC power flow is adopted for the correlated calculations among random variables in the planning model.4 A novel multi-objective transmission planning approach that considers transmission investment profit is proposed. Requests for transmission investment profit and social welfare are involved in the proposed planning approach.

Due to the development of computer and the popularization of Internet, more and more enterprises have adopted the computer network for the data communication to achieve the commercial business transaction or factory control. However, the data transmission in network is complicated and unforeknown. Thus, it will get some problems or affect the system operation if data are lost during the data transmission. The TCP/IP protocol is currently one of the most popular communication protocols. And the service quality from user request will be higher and higher. Therefore, How to provide the high–quality data communication and avoid the data loss is the goal of this thesis.

随著电脑技术的进步以及电脑网路的普及，愈来愈多企业体系利用电脑网路来做资讯交换，以达到商业交易或工厂控制的目的，而网路传输状况难以预测，若在资料传输过程中发生资料遗失，小则造成资料不对，大则造成应用系统无法正常运作，现今工商业对网路应用的依赖度愈来愈大，稍有闪失，都有可能招致莫大的损失， TCP/IP协定是目前网际网路上最被广泛使用的通讯协定，而目前使用者对其服务品质的要求也愈来愈严格，因此，如何在现有的网路下避免资料遗失及提高通讯品质，就是本篇论文所要探讨的课题。

At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.

随着邻体数目的增加，病毒的感染力度变得更大而且在空间上形成聚集的波形；(5)生境破坏及其空间结构在一定范围内有利于疾病的控制，这暗示人为对生境的干扰可作为疾病控制的一个潜在方法；(6)生境破坏的数量以及不同类型生境的空间分布格局都显著地影响了寄生病毒的入侵和传播，生境破碎化程度越高(高丧失斑块的数量或低聚集程度)，将越有害于病毒的入侵和传播，这暗示了空间异质性是否有益于物种的入侵依赖于所考虑的生态过程；(7)由生境破坏引起的空间异质性的两个组分之间存在负偶联关系trade-off(8在适度的生境破坏范围内，宿主种群能够平衡生境破坏带来的正负两种效应并呈现增长趋势；(9)在捕食-食饵系统中，寄生感染病毒极有可能在生境破坏量较低时爆发；(10)物种在面临生境破坏或者其它环境压力时表现出更高的聚集分布策略；(11)寄生-宿主/食饵-捕食生态传染病系统与共位捕食食物网结构具有相似的生物机制，其中捕食者扮演共位捕食者的角色，已感染食饵作为共位食饵，易感染食饵扮作共同消耗的资源；(12)位于最高营养级水平的种群对生境破坏的响应不一定是最敏感的，这不仅依赖于内在的生物机制同时也依赖于外在的环境干扰。

It is found that comparing with compact single circuit transmission mode, T-type compact transmission mode of two circuits on the same tower and conventional transmission mode of two circuits on the same tower, the transmission mode of two circuits with same phase sequence in the same tower window need narrower corridror width, and the radio interference and audible noise caused by this transmisison mode is relatively lower, especially, the corona loss is reduced evidently, thus better economic and social effects can be obtianed by applying this transmission mode in a short distance under a centain condition.
