查询词典 numerical technique

Numerical simulations by assemblies of circular panicles can qualitatively reflect the general characteristics of liquefaction behavior of sand. The interval effect of aspect ratio of elliptical panicle on the mechanical behavior of numerical sample is obtained, and the reason is related to the initial average co-ordination number. The regularity of evolution of fabric in the process of sand liquefaction under cyclic loading can be qualitatively achieved by using the numerical sample randomly mixed of panicles with different shapes. Numerical simulations can not only demonstrate the macro phenomenon of particle breakage, mostly importantly, it can also expose the evolution of particle breakage microscopically, and would contribute to further research of the micromechanics of particle breakage.

研究结果表明：Hertz-Mindlin非线性接触模型适用于变围压条件下砂土力学性质模拟；纯圆颗粒模拟能够定性地反映饱和砂土振动液化的一般规律；颗粒长短比变化对砂土力学性质的影响具有区间效应，其原因与粒间初始平均接触数有关；不同形状随机混合试样能够从定性规律上反映振动液化过程中砂土的细观组构演化规律；数值模拟不仅可得到颗粒破碎宏观响应，而且可以分析内部接触力变化和实现对粘结破裂位置的追踪，从而可进一步研究颗粒破碎细观力学机制。

The possiblehost objective reason all is very many, but, our country numericalcontrol engine bed function part development backwardness -- varietyfew, unit technical level low, performance quality insufficientlystable, the cost stays at a high level, the delivery insufficientlywas prompt and so on -- not to be able to satisfy the numericalcontrol engine bed main engine product need to develop, had noalternative but to say was most direct, the most main reason, Becauseall numerical controls engine bed all is by each kind of function part(including host 轴头, straight line rolls guide rail, ball bearingguide screw vice-, numerical control tool rest, knife storehousemanipulator, rotary table, numerical control servosystem, surveyfeedback as well as safe protective equipment and so on), the functionpart which on foundation rack and so on the lathe bed, column thecollection attire becomes is the numerical control engine bedimportant component, moreover is the indispensable part.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。

See the advertisement cost and technique cost of station-master, advertise cost mainly is beat of row form station is which, these are little then only several knifes(have a lot of cheap row form a station now), good of then several 100 knifes, opposite to say, the station-master of more willing to give up devotion at least he have a little capital, isn't a poor station-master, be unlikely to get a several knifes to run road;The technique cost is mainly SSL and DDOS technique, encrypting a technique is expensive to have cheapness, the only having of cheapness is several ten knifes, expensive of several then 100 knife a month, defend a DDOS attack's technique generally all more expensive.

看站长的广告成本和技术成本，广告成本主要是打的列表站是哪些，这些少则只有几刀，好的则几百刀，相对来说，越舍得投入的站长起码他有点本钱，不是个穷站长，不至于捞个几刀就跑路；技术成本主要是SSL和DDOS技术，加密技术有贵有便宜，便宜的只有几十刀，贵的则几百刀一个月，防DDOS攻击技术一般都比较贵。

In the procedure of gymnastics athletes' U.C., the functions of the conditional ability performing now are more and more important in the competitive abilities of the floor exercises; besides the sport technique and conditional ability, one should pay attention to the figure in the pommel horse; the importance of the conditional ability is far above the sport technique , and the requirements of the figure are also high in the rings; the characters of competitive abilities of the vaulting horse are similar to those of the floor exercise, in which conditional ability plays a very important role; the requirements of the sport technique in the parallel bars are above those of the conditional ability; the requires of sport technique in the horizontal bar are strikely above those of other individual events, and the psychological ability is above the conditional ability; uneven bars contains much techniques, which means, sport technique is above the conditional ability; balance beam also contains much techniques and requires the least in the conditional ability in women's events, but this individual event demands psychological ability badly. Therefore one should emphasize on the cultivation the psychological ability when U.C. is applied to the balance beam.
