重量减轻

Description: Wood structure :responsibility for structure safety( stability ,absorb windforce and earthquake) Wall and Roof : shelter for wind , rain,and heat.it consist of soil and matchwood.

木架构：承担结构安全性。墙体和屋顶：遮风、避雨、隔热，主要成分为黏土、碎木料，可减轻墙体重量、增进隔热效果。

To get down to this low weight we used titanium and aluminum and removed the piezo ignition.

为尽可能的减轻重量，PRIMUS选择钛和铝作底材料，设计上精简了电子打火器。

One interconnection was between the engine's electrical systems. They were wired so if the electrical system of one engine failed, the other would power both engines. This was not an automatic function, however. Switches on the instrument panel allowed the pilot to cause one engine's electrical system to operate both engines. Because of this interconnection, some weight was saved by virtue of using one full-size battery and a smaller back-up, rather than two full sized ones.

两台发动机之间唯一联系的就是发动机电子系统，如果一台发动机的电子系统出问题了，另外一台的电子系统可以驱动两台发动机，但是这种转换不是自动的，是需要飞行员在仪表板上通过开关切换；这样安排的好处是可以使用一个全尺寸的电源和一个小的备份电源，与两个全尺寸的电源相比减轻了不少重量。

During the fabrication of big capacity and high lift crane, Crane Company is the first to use the advanced polygonal line technics-- American patent and the special machine for fabrication of polygonal line drum--national patent. The successful use of such advanced technics resolved completely the wire rope enwinding of high lift hoist. It reduced the crane weight and improved the performance of crane.

在大吨位高扬程起重机制造中，首先采用了美国专利的莱伯斯折线卷筒技术和获国家专利技术的折线卷筒加工专用机床，这些技术的成功运用，彻底解决了高扬程启闭机钢丝绳缠绕问题，减轻了起重机的重量，提高了设备性能，使用这项技术的几十个水电站起重设备均取得了良好的效果。

What's more, this type robot solve the coupling of robot's position and posture in mechanism and predigest the arithmetic on control.

在四连杆的实现机构上采用了新型丝传动方式，即简化了机构，又减轻了重量。

But you must reduce weight for 7"8"9 it is very very important.

但你必须减轻重量为7 " 8 " 9 ，它是非常重要的。

Sampling points were obtained by using optimal Latin hypercube design of experimental method,meantime,in order to improve computing efficiency,application of stepwise regression response surface approximate method in the MDO system of the vehicle crashworthiness and free mode of Body-In-White,the approximate model was optimized by using sequential quadratic programming method.

采用最优拉丁方试验设计方法进行样本数据设计，同时，为了提高计算效率，采用了一种新型的响应面构建方法——逐步回归响应面方法构建了整车耐撞性与白车身自由模态多学科系统的近似模型，利用序列二次规划优化方法对此近似模型进行优化，避免了整车碰撞传统优化设计方法计算量大，在碰撞非线性系统优化中常常易导致收敛缓慢甚至不收敛的缺点，在满足了CMVDR294安全法规的同时，使得白车身的扭转模态值得到提高，汽车重量得到较大程度的减轻。

In order to improve performance of uncooled thermal imager, diffractive optical elements are applied in high relative aperture IR lenses.

将衍射光学元件应用于非制冷热像仪的大相对孔径红外镜头与传统设计相比，衍射光学元件的引入，增强了此类镜头的色差校正能力，提高了镜头的成像质量，提高了镜头的透过率，减少了光学零件的数量，减轻了系统重量，为提高非制冷热像仪的性能奠定了坚实基础。

Third, in the fork root space, supplement of reinforcement plate to reduce the sagging amount. Fourth, increase the metal reinforcement on the fork spatial core to reduce the bending.

改善方案中，牙叉空心化具有最大效益，减轻内部与前端重量的影响，可减少近1mm的自重下垂量，不但提高共振频率且内部可增加补强材。

In the 50 cm plough layer per m2 area, the total rootstalk weight of L.

结果表明：赖草株高45~120 cm，单生或丛生，具下伸土壤30~50 cm耕层间有横走根群，每平方米内，深50 cm耕层内赖草根茎总重量为1129.3 g，根茎总长度为2783.3 cm，根茎上的新芽589.7个，使土壤严重缺水，肥力下降；土壤水分在13.4%左右时，对出苗影响不大，对生长发育有很大的影响；气温在-6~6℃，根茎萌发出土，高峰期为4月上旬，平均单株结种量为468.4粒；每平方米内有赖草120~160株时，大黄产量损失达15.8%~17.8%；田间每平方米内有赖草1株时，采用人工或机械深耕捡出地下根茎，减轻翌年危害来源。
