Certainly some of these individuals may have physical limitations that make activity extremely difficult , and others are engaged in time - consuming activities that until finished do not permit opportunities for recreation 译：当然，这些人中有些人可能有身体方面的限制，活动起来极为困难，有些人从事一些费时的活动，直到完成才有机会来娱乐休闲。
Cad is software that can help engineering in their designs for new products building , print circuit boards , civil works like bridge and airports , relieving them from the tedious , back = breaking and time consuming jobs like drafting and drawing Cad是这样的软件，可以帮助工程师设计新产品、建筑、印刷线路板、桥梁和机场等土木工程；使他们从绘图等繁琐、累人和费时的工作中解脱出来。
Of course , helping your baby drink from a cup is time - consuming ; unless you use a cup with a spill - proof top ( commonly known as sippy cups ) or a built - in straw , you ' ll have to help her drink and be prepared for the inevitable mess 当然，帮助小宝宝习惯从杯子中喝奶是非常费时的；除非你使用上端带有防溢设计（通常被称为吸管杯）或者带有一个内置的吸管的杯子，否则你就必须帮助他喝并准备好面对一团脏乱。
Fem and bem is very adapted to predict the noise level in lower frequency , but they need to describe the geometry of structure detailedly which is wasting - time for many modes in system and high frequency , wide band and random variable 有限单元方法和边界单元方法可以较好地预示低频环境噪声，但需要较为详细地描述结构的几何特性。对于时间上是随机的宽带高频分量，结构中存在大量模态的情况有时是费时的。
A team at the harvard school of public health could not find any studies showing whether the time - consuming process of x - raying carry - on luggage prevents hijackings or attacks . they also found no evidence to suggest that making passengers take off their shoes and confiscating small items prevented any incidents 研究人员称，目前没有看到有研究表明，对旅客行李费时的x光检查避免了劫机或恐怖袭击行为，让旅客脱鞋并没收小件物品也没有避免意外事故。
If a listener is going to perform a potentially time - consuming operation like processing a large document or doing something that may block , such as performing socket io , it should arrange to do that work in another thread so it can return to its caller quickly 如果侦听器要执行一个可能比较费时的操作，例如处理大型文本，或者要做的工作可能阻塞，例如执行socket io ，那么侦听器应当把这些操作安排在另一个线程中进行，这样它就可以迅速返回它的调用者。
Moreover , because of the weakness of taking too much time in fractal coding , zerotree wavelet has been used flexibly in the process of coding , which deleting a lot of predictable and unimportant coefficient , at the same time making them equal to zero , thus the coding time has been shortened 而且针对分形编码比较费时的弱点，在具体编码中灵活地运用了零树概念，舍弃了大量可预测的无意义数据，同时对这些无意义数据置零，从而达到缩短编码时间的目的。
5 . the seed fill algorithm in graphics was introduced into the between - rows weed detection to fill the areas connected with the centre of the crop row . in order to gain the faster processing speed , an improved scan - line seed fill algorithm was developed successfully 根据杂草多数分布于作物行之间的裸土区的位置特征，首次引入图形学中的种子填充算法识别行间杂草，并且针对传统种子填充算法比较费时的缺点，研究改进的扫描线种子填充算法，显著提高了填充速度。
Also , think beyond cooked and elaborate traditional breakfasts , and choose foods from the starchy cereals and grains ; high calcium ; fruit and vegetable food groups : quick , cold dishes such as breakfast cereal and dairy or soy milk or breakfast bars with a carton of juice or milk ; pots of yoghurt , fresh or dried fruit ; rice crackers with a sweet or savoury spread , buns or other lower fat bakery goods offer easy grab - and - go options , that can be eaten on the way to work or school if necessary 此外，不要只想到烹调的早餐和精心制作的传统早餐，从淀粉类谷产品高钙食品水果和蔬菜类食物中选择早餐：不费时的冷食物如谷类早餐奶制品或豆奶早餐棒外加一纸盒装的果汁或牛奶酸奶以及新鲜水果或干果加糖或涂了香料的米制饼干而小圆面包或其它低脂面包更容易吸引你去选择，因为必要时它们可以在上班或上学的路上吃。
Modeling of mechanics multibody system is the primary sustaning technology of virtual prototype . it is the base of virtual prototype to realize simulation . design and control . the technology of virtual prototype has changed the tradisional design based on physical prototype , and has greatly reduced the expensive and time wasting manufactrue and exprements of physical proto type . it allows the users analyse and compare rared of designe plans fastly . it can realize optimized design , and can find the potential questions in the early design . it is the effective method to improve qualities of products , to shorten the developing cycle , and to reduce the developing cost 机械多体系统动力学建模是虚拟样机的主要支持技术之一，它是虚拟样机实现仿真、设计制造和控制运行的基础。虚拟样机技术改变了传统以物理样机为基础的设计，大大减少了昂贵而费时的物理样机制造及试验过程，使用户可以直接在计算机上快速分析比较多种设计方案，进行优化设计，在设计的早期及时发现潜在的问题，是提高产品质量、缩短产品开发周期，降低产品开发成本的有效途径。
