stationary

A point at which the derivative changes sign.See stationary point,in mathematics In mathematics,particularly in calculus,a stationary point or critical point is an input to a differentiable function where the derivative is zero (equivalently,the slope of the graph is zero):where the function "stops" increasing or decreasing (hence the name).For a differentiable function of several variables,a stationary or critical point is an input (one value for each variable) where all the partial derivatives are zero (equivalently,the gradient is zero. For the graph of a function of one variable,this corresponds to a point on the graph where the tangent is parallel to the x-axis.For function of two variables,this corresponds to a point on the graph where the tangent plane is parallel to the xy plane. The notion extends to differentiable maps from Rm into Rn and to differentiable maps between manifolds,but,in these case,only the term critical point (or sometimes bifurcation point) is used,not stationary point. This article focuses only to the case of the functions of a single variable.For the other cases,see Critical point.

更新1: 但系我系书上面又见到句咁既野:wave speed of the a stationary wave is not zero. It refers to the speed of the o wave travelling in oppostie direction which result in the stationary wave.咁姐系点? 更新2: if stationary wave 既speed系0既话 咁v=f入又可唔可以apply系佢度?另外 我系书度又见到以下呢一条mc: 一个stationary wave有个4个loops 入=0.4m A vibrator vibrates at 50Hz to produce a stationary wave. What is the wave speed of the stationary wave? A.10 ms^-1 B.20 ms^-1 C.30ms^-1 D.40ms^-1 答案是b 咁姐系点? speed of the stationary wave点解系呢度又唔系0?? 更新3: 很感谢你一直答我问题。我在维基看的:由于波的行进速度v为「其频率f和波长λ的乘积」，且为「弦所受张力F *** 的线密度μ的比值之平方根」，可知弦上形成驻波时，其频率f为：f=v/入=nv/2L 如果V of 驻波=0 那么frequency不就是0吗?这可行? As the name implies a "stationary wave" is NOT moving (though it has vibration of its particles). The speed of the wave is thus zero. A stationary wave is formed by o travelling waves moving in opposite direction to each other. The resultant wave has zero velocity as can be observed on any one of the crests (called antinodes) that always remains at the same position. The wer of 4.8 m/s is just the speed of one of the travelling wave that produces the resultant stationary wave. 2011-09-13 21:23:16 补充： The speed of a stationary wave is clearly NOT equal to the speed of the travelling waves from which the stationary wave is formed. The speed of a wave is the speed of motion of the crest (or trough). The crest (antinode) of a stationary wave possesses no trlational motion at all. 2011-09-18 15:48:32 补充： The equation: v =f.入 applies to a travelling wave. 2011-09-18 15:50:21 补充： The wer to your quoted question is certainly not right. 20 m/s is the speed of the travelling waves from which the stationary wave is formed. The speed of stationary wave = [20 + (-20)] m/s = 0 m/s 2011-09-18 15:51:21 补充： You cannot take the speed of a travelling wave as the speed of the stationary wave.

设置只有当车辆静止

stationary pendulum的中文翻译stationary pendulum 静止的钟摆

B.for等介词 后面肯定跟doing 形式,这个规律可以记住,很有用.另外knock off 是撞得掉下来的意思,knock on 是敲门的敲.意思上当然是B正确了.

what is “company stationary”什么是“公司文具”我是来自于“百度资源共享”芝麻团的团长：善良的我啊你答案满意请采纳谢谢思密达

意思是 保持静止

movelesscar是表示动也不动的车子，stationarycar是指静止的车子。moveless是不是那种本来可以动的但不动stationary是本来就不能动的。

应该可以用中文回答的吧,需要英文版追问我. 先求导f"(x)=4ax^3-6x^2+2bx+2 有因式（x+1）,即当x=-1,f(-1)=0=a+2+b-2=a+b (1) 当x=1/2时有极值,即f"(1/2)=0=4a*1/8-6*1/4+2b*1/2+2=a/2-3/2+b+2=0 (2) 由方程（1）（2）列方程组,即可解得a=1,b=-1

The o travelling waves must be of EQUAL AMPLITUDE. Stationary wave is characterized by the presence of nodes and antinodes. If the o waves forming the stationary wave are not of the same amplitude nodes (positions where there are entirely no vibration i.e. zero amplitude) would never be formed. Also the o waves need to be 180 degrees out of phase. This is the reason why stationary waves are usually formed from the superposition of a wave and its reflection. 不需要。 Stationary wave 是由两个同性质的波(wave of same nature)沿两个相反方向而互相干涉(interference)的效果。在一个closed system入面，只要wave的frequency乎合string的resonance frequency，stationary waves便可以出现。 两个wave一定要有以下的性质。 a. 它们有一个固定的相位差(phase difference)，简单说即要同频率(same frequency)。 b. 它们要是同性质的。 c. 它们的amplitude要是相似的(similar)，不一定要相同。

stationary 固定的;不能被移动的 still 静止的,静寂的 moving的反义词是stationary

stationary和stationery区别：1.Stationary一般作形容词使用，表示“不动的、静止的”例句：It is difficult for me to sit stationary for long periods.我很难长时间不动。He drove the car in a negligent way and hit a stationary lorry.他开车时一疏忽撞到了静止的卡车上。2.Stationery是名词，有两种含义，都和纸制品有关；文具；物品如纸、笔、文件夹、笔记本、等在办公室使用。例句：We supply office stationery for all types of companies and corporations.我们提供所有类型的公司和企业办公文具。

setup only when vehile is stationary.仅当车辆静止时设置。setup体制;组织方式;建制;陷害;栽赃;安装，

stationary point 就是y=5x^3-3x^5的一阶到等于0，然后就可以求出stationary point 的X的坐标，然后代进y=5x^3-3x^5求Y的坐标就行了。Nature就是 这个点是Local max 或者是local min

你好,为你解答,正确答案为：stationary bike健身车；固定自行车；固定脚踏车；固定式自行车不明白请及时追问，满意敬请采纳，O(∩_∩)O谢谢

事实上，这两个是一个意思，只不过stationary wave 是英国用法，standing wave 是美国用法。

翻译的话没有区别但是就原文讲，两个词还是有些微区别的，fixed就是完全不变，stationary是总体保持不变，允许一些轻微的细小的变化的。

意思区别很大阿。。。

你的问题前后好像不对应，题目写的是stationary，下面写的是Purchased stationery，这两者在会计学上不是一回事。如果是购买固定资产，当然是cash at bank 和 stationary，然后作为asset的一部分，列报在财务报告里了。如果是低值易耗品（如文具），那就是归于存货科目，当实际领用时，计入费用科目。

stationary和still都有”静止的”的意思,但前者强调”止”,后者强调”静”.static的反义词为dynamic，而stationary的反义词为moving.

stationary和still都有”静止的”的意思,但前者强调”止”,后者强调”静”.static的反义词为dynamic，而stationary的反义词为moving.

stationary财务预算是办公费的意思。还有部分英文和对应意思如下：满意请采纳。

stationary 固定的静止的不能被移动的；固定的不变的still n.寂静, 剧照, 照片adj.静止的, 静寂的adv.还, 仍, 更, 还要, 尽管如此, 依然静止画面,静态图片前面一个应该是moving的反义词

stationary = 静止不动的（固定物体）standing = 站着的（但可能是动的）

stationery英音：["steiu0283u0259nu0259ri]美音：["steu0283u0259n,u025bru026a] 名词 n.1.文具;信纸[U]不可数 stationery and envelopes 信纸信封

stationary这个单词的意思是1，Notmoving.静止的2，Notcapableofbeingmoved;fixed.不能被移动的；固定的射击打靶，移动靶子是与静止的靶子相对应，所以应该选stationary。从另一个角度来说，standing虽然也有固定的意思，但是它的固定是停滞不前的那层意思，如下：1，Notmovable;stationary.不动的；停滞的2，Notflowingorcirculating;stagnant.不流动或不循环的；停止不前的这回可以分清了吧：）

stationary是文具的意思。pencil铅笔 pen 钢笔ruler尺子 rubber 橡皮stapler 订书机 扩展资料 　　stationary其他意思： 　　adj.不动的;静止的;固定的`;不可移动的;不变的;稳定的 　　n.不动的人;驻军;固定物 　　复数： stationaries 　　例句： 　　Stationary cars in traffic jams cause a great deal of pollution 　　交通堵塞中静止不动的汽车产生了大量污染。 　　The car collided with a stationary vehicle. 　　小汽车撞到一辆停着的车上。 　　I remained stationary. 　　我待着没动。

意思是：固定的，静止不动的。另外还有个很相似的单词，Stationery,意思是：文具。

这些词其实严格来说，并不都是固定的意思，只不过字典上笼统这么解释了。每个词都有自己固定的用法和意思。fixed和settled有一层相近的意思，表示某某事情办妥了，某某问题解决了。当然fixed还表示某东西被固定好了 settled还表示人的生活或工作稳定下来了。constant有一层意思是持续的。stationary是表示静止的意思，就是物理学上那种。stable有一层意思是稳定的，比如某某趋势比较稳定，或者某某家具放在地上很稳，自身不会歪倒或摇晃，但并不像fixed是用螺丝或什么完全固定住的。
