Several questions to select the magnetic float gauge for liquified gases tank are introduced,measurements and calculation of float part are suggested,which can provide some guides for the selection and inspcetion of magnetic float gauge .

介绍了液化气体储罐磁浮子式液面计的浮子元件选用应注意的问题和检验中对浮子元件检查、测量及相关的计算方法，为磁浮子式液面计的选用、检验提供借鉴。

All the actuators of the three-axis turntable are brushless torque motors, all the bearings are aerostatic air bearings, so the friction caused by these elements can be neglected. The main source of friction is the metal-to-metal friction on the slip rings. Hence the "Columb+Viscous+Static" friction model is used here for analysis.

由于三轴转台的驱动系统选用的是无刷电机，轴承则采用的是气浮轴承，轴系上的摩擦力已大大降低，三轴转台上的摩擦主要是滑环轴上金属对金属的摩擦，所以文中选用&库仑＋粘滞＋静摩擦&的摩擦模型来进行分析。

In the bead-on-plate experiment, the trial pieces were SAE1020 steel, the activating fluxes were oxide, Carbonate, Sulfide and fluoride, and the welding method was argon shielding gas tungsten arc welding without filler metal.

实验材料选用SAE1020，活性助焊剂选用氧化物、碳酸盐基、硫化物及氟化物，焊接方法采用不加填料金属的氩气保护钨极电弧焊来进行Bead-on-plate实验。

Grapeseed: A bit pricy, but keep in mind, grapeseed oil lowers cholesterol. Use it when you'd use olive oil, and since it has a higher smoke point, it's also good for frying and sautéing.

葡萄籽油：有点贵，但记住，它可以减低胆固醇，所以选用葡萄籽油就如选用橄榄油一样，同时它有一个较高的冒烟点，非常适合煎炸和中火炒。

A disinfectant Iodophors can be mixed with soft surfactants and additives to produce a new hand cleaner .

选用&碘伏&作为抗菌消毒剂，并选用多种温和表面活性剂和添加剂研制了新型洗手液。

Therefore, in order to guarantee the stability of production, but also to reduce the actual running costs, heat-conducting oil bellows system should be chosen cut-off valve can not be selected filler valve seal or valve.

因此，为了保证生产的稳定，也为了降低实际运行成本，导热油系统应该选用波纹管截止阀，不能选用填料密封的截止阀或闸阀。

If is the gentle introversion disposition, may select the thin flower, be light yellow or the hermosa pink series, on the flower, may select the lofty figured, or is craft good embroidering, in quality of material, best choice gentle silk-weaving, cotton and kapok, chemical fiber and so on.

如果是文静内向型的性格，可选用细花、鹅黄或浅粉色系列，花型上，可选用高雅的织花，或者是工艺良好的绣花，在质地上，最好选择柔和一点的丝织、棉、化纤等。

The first one is approach difference. More than 90% Chinese patients prefer to accept infra-axillary approach for they thought that the incision scar is unobvious. But western patients prefer to accept peri-areola approach and seldom accept infra-axillary approach. For they thought that they like to expose their infra-axillary and then the scar would be found more often.

切口选择：中国求美者大部分约90%愿意选用腋下切口，觉得腋下切口隐蔽；而西方求美者大多选用乳晕切口，很少用腋下切口，因为西方人穿着比较暴露，腋下暴露的机会比较多，会让人看到手术痕迹。2。

Dining and living room walls, the ground, the choice should be easy to clean and kitchen materials, the ground the best choice of floor tiles, floors and other materials to strengthen, Shun Putie wood floors, wood floors vulnerable to heat because of impact deformation, among easily picked up a trace oil pit.

餐厅和客厅的墙面、地面应与厨房一样选用容易清洁的材料，地面最好选用地砖、强化地板等材料，切忌铺贴实木地板，因为实木地板容易受热气影响产生变形，缝隙间也容易沾上油污。

Screw on the choice of friction loss, high efficiency, high precision, long life of the ball screw, the electrical selected stepper motor, motor and the ball screw with gear deceleration.The main to modify the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser. The whole control system with the CPU of JKW-15T is to control the machine for center, through a plait distance drive tool machine an equipments to carry on control to attain need of process degree.

整个改造过程主要对车床纵、横向进给系统进行改造，丝杠选用摩擦损失小，效率高，精度高，寿命长的滚珠丝杠，电机选用步进电机，电动机与滚珠丝杠用齿轮减速；刀架改造成能自动换刀的回转刀架，由脉冲发生器来加工所需要的螺纹；整个控制系统以JKW-15T型号的单片机为中心，通过编程对机床的驱动设备进行控制以达到所需要的加工程度。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
