查询词典 at the maximum

The results show that new residual stress is about 6MPa under air-cooled normalizing; due to chilling effect of surface quenching, the temperature differences between coarse bar and thin bar in stress frame, and between surface and core of the coarse bar are tremendous; in quenching process, the stress of the certain areas in the coarse bar is maximum at 2s, more than 420MPa, the stress frame casting has the bigger possibilities of fracture.

结果表明，正火空冷时新产生的残余热应力约6MPa；淬火时由于表面激冷作用，应力框在粗细杆间及粗杆的表面和芯部都有巨大温差；铸件在淬火的过程中，粗杆的某些部位在2s时等效应力达到最大，超过了420MPa，极有可能导致铸件断裂。

The results show that the mill current and particle filling increased with the coal feed flow when ventilation rate remained the same, mill current started to decline after rising to a peak, the beginning of the decline region corresponded to the optimal particle filling, at this point, the gap between balls were just full of coal particles, the mill was running close to maximum power, and grinding efficiency reached the highest.

研究结果表明，磨煤机通风量不变时，随着给煤量增加，磨内存煤量增加，磨煤机电流升高，电流上升到峰值后又有所下降，开始下降的区域对应的料位是最佳运行料位，此时，钢球间隙中刚好充满了煤粉颗粒，磨煤机接近最大功率运行，粉碎效率达到最高。

Adding transition metals into the TiN films by arc ion plating (1) The hardnesses of theN films are higher that that of the TiN films, proving that the alloy hardening effect is a common phenomenon;(2) The structures of the alloyed films are determined by the added element properties such as covalent radius, electro negativity, free energy and lattice parameters of the MN compound;(3) theN film consists of a mixture of multi phases with high hardness but quite brittle, while the other MN films are composed of single phase with the fcc TiN structure and their hardesses, functions of the added amounts of the elements, manifest always a maximum at a certain M percentage.

一、将过渡金属M用电弧离子镀方法添加于TiN薄膜中：1。N薄膜硬度均高于TiN薄膜硬度，合金强化效应普遍存在；2。薄膜相结构决定于添加元素M的周期律信息，包括M的共价半径、电负性，及MN化合物的自由能、晶格常数等；3。N为多相混合结构，薄膜硬度高，但韧性差；其它N的相结构为TiN类型的单一fcc结构，薄膜硬度随M添加量变化并出现峰值；4。

Minimum investment for maximum interest is the internal origin of insurance swindling; the policy-holder, the insurant, the beneficiary or the clerk of the insurance company take advantages of the bugs in insurance contracts and insurance company management to aim at illegal income by means of inventing insurance object, producing false notice about the risk faced by the insurance object, repeating buying the same insurance item, or buying insurance services via insurance object without insurance interest.

投保人以较少的&投入&获得奇高的回报，是保险欺诈产生的内在基础；投保人、被保险人、受益人或者保险公司的工作人员利用保险合同与保险公司管理上的缺陷，通过虚构保险标的、对保险标的所面临的风险做虚假告知、购买重复保险、以不具有保险利益的保险标的投保。

Extrapolating the equation to the second phase of the Little Ice Age of the glacier, and inferring the equilibrium line altitude at that time from maximum elevation of lateral moraines, the climate condition during the phase can be determined. The result is closed to the previous outcomes deduced by other methods.

将公式外推到小冰期第二次冰进时的1号冰川，并运用侧碛垄最大高度法确定了小冰期第二次冰进时冰川的平衡线高度，给出了该次冰进时气候条件的半定量推算结果。

The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.

应用ADAMS软件对小麦免耕播种机悬挂机构提升过程进行了动态仿真，得到了工作部件的位置高度、工作部件与拖拉机后轮之间的间距、路面通过角以及悬挂点的受力等参数，找到了悬挂机构的关键参数，通过优化仿真，得到了悬挂机构的最佳工作参数，仿真结果表明，设计变量DV_2、DV_3在结构受限范围内分别取其最大值和最小值，悬挂机构悬挂点受力最小。

The set of feasible operations that allocate time optimally among the three heat conduction branches for the objective function be written in terms of the net effects and the finite-time constraint are explicitly described. The result generalizes the well-known result of Curzon and Ahlborn for the efficiency of a Carnot-like heat engine at maximum power.

描述了三个恒温热源之间一切可行的循环方式，在有限时间的约束下，根据净效果定义的目标函数对热传导分支运行时间进行了优化分配，推广了类卡诺热机在最大输出功率时Curzon和Ahlborn所得到的效率结果。
