查询词典 set over

"A set of elements having two operations, designated addition and multiplication , satisfying the conditions that multiplication is distributive over addition and that both operations are associative and commutative for all elements of the set, with the exception of the additive identity element, which is not commutative in respect to multiplication ."

"一组元素，进行加法和乘法两种运算，满足条件：乘法运算需分配于加法之中，这组元素要将这两种运算结合且换进行，附加的就乘法而言不可交换的恒等元素除外。"

Mathematics A set of elements having two operations, designated addition and multiplication, satisfying the conditions that multiplication is distributive over addition and that both operations are associative and commutative for all elements of the set, with the exception of the additive identity element, which is not commutative in respect to multiplication.

域，体：进行加法和乘法两种运算的一组数，满足如下条件，即乘法分配律同样适用于加法分配律，各数在做加法和乘法两种运算中可相互结合并交换，但在乘法中不可交换的加性恒等幺元除外

Object: To solve the problem of the flux control set of unfitting GMP demand in large infusion filling machine for soft packaging. Method: Using methods of metage and electromagnetism flux-control to amend quantitive set. Result: The check-out rate of the finished product has achieved over 95% after modification.

目前，市面上所见的国产软包装大输液灌装机普遍存在一个致命的缺陷，即灌装机的定量控制都采用涡轮式流量计，该种流量计使用在大输液生产中，有两点不符合GMP要求：(1)该种流量计属于接触式流量计，与药液接触的元件——涡轮，由磁性材料做成，耐腐蚀性能差，而且会产生脱落物；(2)由于结构上的原因，涡轮流量计内部本身存在死角，不便于清洗干净。

If ris also irreducible in Z_nand f~n~κ≡fmodn,r(xfor all f∈Z_nthen we call n a Carmichael number of orderκmodulo r.Denote the set of all such numbers by C_κ,r(x.Define C_κ=∪_r(xC_κ,r(x,where rpasses through all monic irreducible polynomials over Z of degreeκ.We call elements of the set C_κCarmichael numbers of orderκ.ZHU and SUN[Journal of Sichuan University,42;1(2005), 47-51]first gave a necessary condition for Carmichael numbers of order 3.Then they gave a sufficient condition for Carmichael numbers of order 3,but did not find any such numbers less than 10~8 satisfying the sufficient condition.At last,they asked three questions;1.is the necessary condition also sufficient?

f∈Z_n，就称n是模r的κ阶Carmichael数，用C_κ，r(x表示所有这种数的集合，定义C_κ=∪_r(xC_κ，r(x，这里r跑遍Z中所有κ次首一不可约多项式，C_κ里面的元素就称为κ阶Carmichael数，C_κ称为κ阶Carmichael数集，朱文余和孙琦[四川大学学报，42；1(2005)，47-51]首先给出了3阶Carmichael数的一个必要条件；然后又给出了这种数的一个充分条件，并发现10~8内没有满足此充分条件的这种数；最后他们提出三个问题；一、问必要条件是否也是充分的？

A big red flag to signal a warning sign, is when ever an alien, or off plan et group of aliens claims that they can come and "set those of Earth on the right track"(by implying that Humans have botched the job so badly in managing their planet that now their galactic "creators" must come and take over the Earth and set it right).

When it was dark I set by my camp fire smoking, and feeling pretty well satisfied; but by and by it got sort of lonesome, and so I went and set on the bank and listened to the current swashing along, and counted the stars and drift logs and rafts that come down, and then went to bed; there ain't no better way to put in time when you are lonesome; you can't stay so, you soon get over it.

天黑了，我在营帐边上抽着烟，心里觉得挺满意的。慢慢地又感到有点儿寂寞。我便在河岸上坐下，倾听着流水冲刷河岸声，数数天上的星星，数数从上游漂下来的木头和木筏子，然后去睡觉。在寂寞的时候，这是消磨时间最好的办法了。你不会老是这样的，你很快就会习惯的。

Considering the characters of the viscoidal turbulent flow over high-speed train,the computing model of the outer fiow field for high-speed train has beenestablished based on the incompressible fluid Navier-StOkes epuation and theturbulent model of ke two equations.
