Owing to various influential factors , a great deal of calculation and imperfect design theory , experience always plays an important part in the technical decision of ground improvement 在软基处理技术决策中，影响因素众多，计算工作量大，设计理论不完善，经验往往起重要的作用。
Original pattern and lively explanation . in order to show the teachers teaching level and charisma , they prepared actively and overcame many difficulties , such as short time and much work 为能充分展示我校教师的教学水平和风采，各位参赛教师克服时间紧，工作量大等种种困难，积极准备。
But its shortcoming is having many work to do . when the number of reservoir is raising , the disaster of dimension will be happen , and some other way should be adopt to reduce the dimension 但其缺点是计算工作量大，水库数目增加时，会产生“维数灾”问题，需要借助一定的方法来降维。
The popularize of cbt was embarrassed by the problems existing in current cbt courseware development tools , such as long development cycle , big amount of work , and low quality of courseware 现有的类似课件开发工具存在开发周期长、工作量大、课件质量不理想等问题,影响了cbt的推广和应用。
Previously , a highly - precise printing work of a4 with ink printers always needed 10 minutes to be printed . when the printing volume was large , a part of the printing task had to be contracted outside 以前用喷墨打印机打印高精度图像时，一张a4常常就需要10分钟，一旦工作量大，就需要将部分打印工作外包。
But at present , the design way is still rest on the two - dimensional stage , the workload is great , the course of design isn ’ t intuitionistic and the errors in design courses are not been detected easily 但是目前的设计手段还停留在二维阶段,工作量大、设计过程不直观、设计过程中的错误也不容易发现。
The relay regulation of power plant is very important , its workload is too heavy and the process is miscellaneous . the computation of regulation is still completed by hand at present 发电厂保护整定工作非常重要，但它的工作量大且过程繁杂，目前保护整定依然停留在人工手算阶段，这具有不可克服的缺陷。
For the long time , it had being used the human and computer reports mode to collect the production data in the hot strip mill , then reported to company after processed by human 长期以来,热轧板厂都是采用人工报表、计算机报表的方式对生产数据进行收集,然后经人工整理后上报公司,工作量大、数据收集不及时。
Time - history analysis requires much time , workload and high capability computers . the evaluation of result requires much theory knowledge . so , this way is hard to spread 时程分析工作量大，费时，对计算机性能要求较高，对分析结果的评估需要较高的理论知识，不便于推广应用，设计人员需要一种简单实用的简化分析方法。
In accordance with the question of big workload of drawing and difficult found of gallery of faclity in cad of coal preparation plant , this paper analyses the characteristics of the shape sameness and size unlikeness 就选煤厂计算机辅助设计中存在的绘图工作量大、设备图库建立困难的问题，分析了某些形状相同、大小不同的设备的特点。
