Typically, operator involvement in a computer controlled lyophilization cycle primarily occurs at the beginning. It consists of loading the chamber, inserting temperature probes in product vials, and entering cycle parameters such as shelf temperature for freezing, product freeze temperature, freezing soak time, primary drying shelf temperature and cabinet pressure, product temperature for establishment of fill vacuum, secondary drying shelf temperature, and secondary drying time.

包括前箱的摆放、向产品瓶中插入温度探头，输入循环参数，例如：板层冷冻温度、产品冷冻温度、追加冷冻时间、主干燥时的板层温度和前箱压力、开始抽真空时的产品温度、第二次干燥时的板层温度、第二次干燥的时间。

Increase the bearing box on exhaust diameter bearing box will help to maintain the pressure at atmospheric pressure, but will also have more pollutants to enter.

加大轴承箱上排气口口径有助于将轴承箱中的气压保持在大气压力，但是也会有更多的污染物进入。

The static and dynamic characteristics of the beam of a gantry-type machining center are analyzed by means of ADAMS and ANSYS. Considering effect of gravity and cutting forces, the static deformation of the beam is obtained after calculating the interacting forces between the guide and the slide block by ADAMS. Moreover, the contact parameters of the guide surface are acquired by dynamic tests and parameter identification, then they are applied to the simulation model of the beam-slide box system, whose natural frequencies and modal shapes are achieved by modal analysis. Furthermore, the effect of changes of the contact parameters on the dynamic behavior of the beam-slide box system is also investigated.

对一种国产龙门式加工中心的横梁关键部件，采用机械系统多刚体动力学仿真软件ADAMS和有限元分析软件ANSYS进行了静动态特性分析；在考虑重力和切削力作用下，由ADAMS计算出导轨与滑块间的作用力，从而计算出横梁部件的静态变形；通过动态测试和参数辨识方法获得导轨结合面特性参数并将其应用到横梁滑箱系统整体有限元模型中，经过模态分析得到系统固有频率和各阶振型图，并进一步分析了结合面参数变化对横梁滑箱系统整体动态特性的影响。

Against the curved box girder bridges in highway bridges and urban viaducts,the curved grillage model of the multi-cells curved box girder is built in terms of the shear-flexible grillage method,and the analysis for the vehicle-bridge interaction is performed.

针对公路和城市立交中的曲线箱梁桥，基于剪力柔性梁格法建立了曲线箱梁的梁格模型，进行了车桥相互作用分析。

Moreover, he adds, the gearbox is made from the same kind of steel that is already used in the small gearboxes that take power from turbofans for aircraft systems.

他还补充说：制作减速器所用钢材与已经用于涡扇发动机中的齿轮箱所用钢材是完全相同的。飞机上的其它系统靠这个小型齿轮箱从发动机获取动力。

In the project of cross-under the highway with pipe roof and culvert box method,the interspace between culvert box and pipe roof is limited by several factors.
