solid-beam efficiency

By adopting spiral cutting instead of traditional barrel shaped cutting in the course of digging tunnels in the solid marble strata of Yinan Gold Mine, the blasting efficiency and result were improved besides the consumption of materials was lowered.

沂南金矿在较坚硬的大理岩层中掘进巷道时，采用螺旋掏槽替代传统的桶形掏槽，可改善爆破效果，提高爆破效率，降低材料单耗。

In this paper, Parameter Variable technique is used to establish finite element model for trailer frame of 60 ton heavy transport truck, and 10-Node Tetrahedral Structural Solid elements are used for FEM mesh, which greatly improves building efficiency, revisability and of model than tradition methods.

采用参数化建模方法建立了60t重型半挂车车架有限元模型，采用曲棱四面体等参单元比传统方法提高了建模效率和可修改性以及计算精度。

We specially prove that the reradiation efficiency and the resonance width are nearly proportional to th imaginary part of the corresponding pole for most solid objects immersed in water.

我们特别证明，对于大多数水中实弹性体，再辐射效率和共振宽度近似地正比于相应极点的虚部，这说明共振散射特性可以整个地由复频率极点确定。

The structural space of thrust termination mechanism in the solid motor is very limited. In order to meet the demand that negative thrust of the motor is not less than zero, efficiency of reverse thrust must be improved as far as possible.

某固体发动机推力终止装置结构空间十分有限，为保证推力终止时发动机负推力大于等于零的要求，必须尽可能地提高反推力效率。

Compared with the conventional alternator, homopolar inductor alternator was very suitable for the self-contained power system, for the solid forging rotor can run high speed, its moment of inertia is large, and its efficiency and power density are very high.

因为同性极感应子发电机的转子强度高适合高速旋转，转动惯量大，电机的功率密度和效率可以做的很高，这些对系统是很有利的。
