查询词典 viscous force

Our grab nickel production, nickel is mainly used to crawl,铁精粉, red clay minerals such as highly viscous due to the recent nickel 铁精粉, red clay and other minerals to be widely used, so Many major ports on the existence of such a problem, in which the ore handling when loading and unloading there is a low efficiency, has been a lot of ore grab adhesive wall, our company in order to solve this dilemma has been studied and produced by such a professional crawl very sticky ore grab, the principle is: grab the next 承梁 calculated to increase the adoption of two pieces of solder, including the specific location of board and grab the bucket to create a circular flap, so Open grab discharging, the fight is on board, including the body wall from the top down (no contact with body panels Doo), to stick the body in fighting the viscous wall down, including mine, so, which greatly improved the handling grab the efficiency of ports and factories to solve the problem, which is purpuratus grab a patent, other manufacturers can not be produced.

普通会员不能显示联方式，只能给他留言我公司生产的镍矿抓斗，主要用来抓取镍矿、铁精粉、红粘土等粘性很强的矿石，由于近来镍矿、铁精粉、红粘土等矿石在被人们广泛使用，因此，许多大港口就存在着这样一个问题，在装卸这此矿石的时候，存在着装卸效率低，抓斗内壁被很多矿石粘着，我公司为了解决这一难题，现已研究并生产出来这种专业抓取很粘的矿石抓斗，原理是：在抓斗的下承梁上通过计算得出要加焊俩块括板的具体位置，并要把抓斗的斗瓣做成圆形，这样在抓斗打开卸料时，括板就在斗体内壁从上而下，把粘在斗体内壁的粘矿括了下来，所以，这就大大提高了抓斗的装卸效率，为港口和工厂解决了这一难题，这种抓斗是紫石的一项专利，其它厂家是无法生产出来的。

In order to describe in detail the structure of mesoscale atmosphere circulation and its evolution, symmetry theory are extensively used in the past fifty years. A large number of wind tunnel and water tank experiments are practiced to reshow the physical process that often appear in the atmosphere and, to some extent, successfully explain many atmsophere circulation characters in surface layer. But because of the planetary reflection and small Re number deformation, these physical experiments can' t represent real conditions of the atmosphere, they also can' t distinct viscous boundary layer separation and non-viscous dynamical separation as well as show the circulation response to surface diurnal heating.

为了详细描述复杂地形区域大气中尺度环流的结构和特征，过去50年来人们广泛采用相似理论，利用风洞和水槽实验再现大气中的物理过程，并在一定程度上成功地给出了大气近地层的一些环流特征，然而由于边界层反射和小Re数形变作用的影响，物理实验的结果并不能真实地再现大气中的实际状况，尤其是不能正确区别边界粘性分离流场和大气非粘性动力分离气流，环流场对地形下垫面日周期热强迫的响应过程也难以再现。

In this paper, a "rigid bar relative movement model" was established to illustrate the traces of the helices in wire ropes. The angular speed of a moving particle of the model was relatives to curvature tensor to derive the curvature components and torsion of helices in multi-layer wire ropes. According to long and thin rod theory of Love and Yen-Chen's theoretical model considered the contact force and frictional force, the force-deformation or force-strain relative of wire in curved wire ropes subjected axial force is derived from the curvature components and curvature increment.

Chapter six presents such new concepts as margin utility contribution force, profit-risk exchange rate, state-expectation-variance utility function, long-term expectation-variance utility curve and optimal portfolio expansion curve. The state-expectation-variance analytical method is developed from the expectation-variance analytical method. The changing rate of profit-risk exchange rate to state variable is used to define and distinguish the decreasing, constant and increasing relative risk aversion. A decomposition formula about the margin contribution force of holding wealth to state-expectation-variance utility function is displayed. The decomposition formula demonstrates that the contribution force of investors' holding wealth to their utility is composed of the pure contribution force of holding wealth and the investment contribution force bronght about through investment portfolio.

The results show that there will be slight decrease of the control efforts when the mean absolute value or the root mean square value of the optimal control force is taken as the maximum designed control force, while the maximum control force of MR damper can be decreased by 85% compared with the maximum optimal control force. The decrease in the designed control force can not only significantly increase the capability of MR dampers, but also reduce the dimension of MR dampers for pratical application in engineering.
