查询词典 speed limit

The experimental group received 10 weeks of walking exercise training, at 50 minuets per session, 5 days per week and at a exercise intensity limit between 60% and 70% maximum heart rate. The control group received ordinary special education curriculums. All participants completed three times of the PACER（Progressive Aerobic Cardiovascular Endurance Run）20-Meter Shuttle Run test and test for the average walking speed during 1600 meters:before the experiment started , after the experiment and the follow-up test at the fourteenth week of the experiment started. All results from these tests were recorded and analyzed by descriptive statistics; repeated measure t-test; the one way analysis of covariance .

实验组进行星期一至星期五每天一次，合计每周五次，每次50分钟，总共10周，运动强度为60％-70％最大心跳率的步行运动；控制组接受学校安排的特殊教育课程，两组学生在进行步行运动前、后以及实验处理结束后第四周，分别接受PACER渐进性心肺耐力跑-20 公尺和1600公尺的步行速度之测验，并将所得的成绩以描述性统计、重复量数t 考验、单因子共变数分析进行统计考验，评估实验处理之运动与维持成效。

Depending on the type of sailboat, often the weight of the ballast can be 30% or 40% of the total displacement of the boat. Heeling of the monohull will create water drag and will create necessity of a wider hull beam that will also in turn limit the speed, thing that was remarked by Archimede 220 years ago.

取决于船只的不同类型，通常压仓物的重量为船排水量的30%。220年前，阿基米德就曾指出过，独体船的倾斜会产生拖水现象和更宽的单体宽度，这样会导致速度受限。

Nowadays, the development of computer graphics systems tends towards features with much higher quality and high speed . Super-microcomputer system with uni-processor could no longer afford the processing capability in these high-end graphics technology fields. By using supermini even mainframe computer would be too expensive. All these factors limit the new application field of computer graphics.

在目前，计算机图形系统向着高质量和高速度发展过程中，由单处理机组成的超级微计算机系统已不能满足图形技术某些领域对处理能力的需求，而用中、小型以致于大型机实现的图形系统成本高，限制了图形系统的应用。

Therefore, the interconnections between chips often limit the performance of a system in applications such as network switches, routers, processor-memory interfaces, and multi-processor interconnects. For this reason, to integrate high speed serial links on chips can reduce the pin/wire count and power budget of a system significantly.

因此，连接晶片之间的传输通道时常限制了系统的效能，这些系统包括网路的切换器、路由器、处理器和记忆体之间的介面及多处理器的传输通道。

The limit to the quants' tinkering has been not mathematics but the speed, power and cost of computers.

数量分析师在此类修补上的局限已不是数学问题而是计算机的速度、能力与成本。

For the application of Balance of heat loss with limit high ,we can choose low a balanced current, high voltage start a balanced, low accuracy, as well as reduce the number of the battery in series to reduce heat loss of balance; In the situation that heat capacity of the battery pack requirements is easy , You can choose a higher balance of the current, low voltage start a balanced, high precision balance, as well as more battery in series to increase the number of battery-balanced speed.

对均衡热损耗限制高的应用，可选择低均衡电流、较高的均衡启动电压、较低的均衡精度以及较少的同时均衡电池数来减低均衡热损耗；而在电池包热容量宽裕的情况下，可以选择较高的均衡电流、较低的均衡启动电压、较高的均衡精度以及较多的同时均衡电池数来提高均衡的速度。
