Through the analysis and research,it was found out that the gate position of the runner system should be selected properly.

经分析认为，模具的浇注系统要选择好浇口位置，浇口形式采用扇形浇口，其尺寸应与产品的有关尺寸相吻合，以保证后续工序的切断加工。

A model of continuous beam with spring supports is put forward to analyse time-dependent structural systems.

针对施工期现浇钢筋混凝土结构的时变性，定义楼板刚度与模板支撑的刚度比为施工时变结构体系的弹性特征值，建立了以施工时变结构体系弹性特征值为参数的现浇钢筋混凝土结构施工受力性能分析的弹性支撑连续梁模型，基于该模型，分析了施工期现浇钢筋混凝土结构的受力特性，发现在特定施工方案下，当施工时变结构体系的弹性特征值较小时，最大施工荷载出现的楼层位置会提前，而拆模时间也会改变最大施工荷载出现楼层的位置；施工时变结构体系的弹性特征值和拆模时间都影响楼层承担的最大施工荷载比率(荷载比率定义为结构承担荷载与楼板自重的比值)；施工期楼层承担的最大施工荷载随楼层位置呈现波动特性，随楼层位置增高波幅逐渐减小，最后趋于稳定。

In this paper, some factors affecting the finished product rate of CSP are analyzed, including the number of continuous-continuous casting heat, breakouts in casting, failures to start a casting process, accidents with rolling mill, molten steel remainders in ladle and tundish, and the percentage of abnormally termin...

本文对影响CSP短流程成材率的各个因素进行分析，包括连浇炉数、连铸漏钢与开浇失败等事故、轧机事故、大包中包注余、非正常终浇比例等，并分析了实际生产中影响成材率的各种情况，提出了提高电炉CSP短流程成材率的措施。

Suspensorily joined structure has the virtue that the construction progress is normally fast and does not hinder the traffic underbridge because Travelling Carriage is not used,but requiring comparatively large construction plant, high complexity in seam assembling, lower structural integrity compared to the suspensorilyplaced are its faults.

预应力混凝土T型刚构加挂梁结构是公路桥梁常用的一种桥梁结构型式，这种桥型根据施工方法的不同可分为悬浇和悬拼，悬浇结构需采用挂篮施工，优点是结构无干接缝，整体性好，刚度大，施工占用场地少，缺点是施工期间挂篮将影响桥下的通航通车，施工周期长；悬拼结构的优点是无需采用挂篮施工施工进度快，对桥下的通航通车影响较小，缺点是需占用较大的施工预制场地，拼装接缝处理难度大，结构整体性较悬浇差。

Six arrises than circular pencil work well, circular pencil market is diverted; straight teeth casting ladle than worm casting ladle work well; also are casting ladle is a popular in market.

六棱铅笔比圆形铅笔好用一点，就挤占了圆形铅笔市场；直齿浇包比蜗轮浇包好用，也会受到浇包市场的欢迎。

Six arrises than circular pencil work well, circular pencil market is diverted; straight teeth casting ladle than worm casting ladle work well; also are casting ladle is a popular in market.

六棱石墨笔比圆形石墨笔好用一点，就挤占了圆形石墨笔市场；直齿浇包比蜗轮浇包好用，也会遭到浇包市场的欢迎。

It can also be made by forging the chevrons of two different kinds of steel, one dark and not watered, and one light and watered. The different pieces are forged together, the blade is now etched, so the light parts show watering but the dark parts do not.

另外这种样式也可以通过锻造合熔两种不同的钢材而制成，一种是暗的没被浇打过的，另外一种是光亮的被浇打过的，将这两者锻打在一起，现在刀身被定型，光亮部分就显示出曾经被浇打过，但暗的却没有

Design methods of two representative runner-the fan gate and tapperd runner system are analysed.

Combined with the design of injection molds and actual production,technical gists ofinjection molding design are introduced on the number of gates,flow pattern,gate position, weldline position and runner design.

结合注塑模设计和生产的实际，重点介绍了注塑模模流设计在浇口数目、流动形态、浇口定位、熔接线位置、浇道设计等方面的技术要领。

However, the pin gate may only be used in certain types of moulds and these are generally more complex in design than the moulds in which sprue gating or side gating techniques are used.

可是，点浇口只能用于某些形式的模具，而且通常在设计上比采用主流道浇口或侧浇口技术的模具复杂得多。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
