变化点

The derivative of a function can be interpreted either as a function whose value at x is equal to the gradient of the tangent line to the graph of y=f at x, or, alternatively, as a function that describes the instantaneous rate of change of y with respect to x at the point x.

一个函数的导数可以理解为一个函数的值无论是在x是等于切线的梯度的y图二F在x，或者，或者，作为一个函数描述瞬时速度y的变化的关于x的点x在f关于x的也可以表示为导数

If in recent several years, I wants to return to the files immediately the opportunity at present, believed this time period Japan's performance really does not acclaim by, no longer is several year ago situation, saw rises slowly Japan economy 225 indices to 10000 spots, pours into one to investor's confidence to inspire the morale the strong heart needle, indeed Japan is the present Asian stock market has not been fallen most to the very deep area, will look like this wave Japan's tidal current also to start to enter the stock market to return warm, no longer will be the topicality which panic does not want to look, you will buy was the initial dollar valuation, therefore also could not feel that kind of double's profit satisfies, if initially purchased Japanese Yen valuation in other places, is also the extra profit, I only may say that in the world to has not favored looked the difference the investment, has a change slightly, will dump tray successfully.

如果是在最近几年的话，我想马上回档的机会就在眼前，相信这阵子日本的表现真的赞叹不以，不再是好几年前的情况，看到日经225指数缓缓上升到10000点，对投资人的信心注入一股提振士气的强心针，的确日本是目前亚洲股市当中最没有被跌到很深的地区，看来这波日本的潮流也会开始进入股市回温当中，不再是令人恐慌不想看的地区性，你买的是当初的美金计价，所以还感觉不出来那种加倍的获利满足，若是当初在其他地方购买到日圆计价的话，也算是额外的获利，我只可以说天底下没有绝对看好看差的投资，稍微有个变化，就会翻盘成功。

The change in net income was primarily attributable to a $26.9 million decrease in research and development expenses related to the cessation of the development of Sulonex in March 2008, a $5.4 million decrease in research and development expenses related to KRX-0401, a $20.8 million increase in license revenue related to an amendment to the September 2007 sublicense agreement with Japan Tobacco Inc. and Torii Pharmaceutical Co., Ltd. which eliminated the Company's significant ongoing obligations included in the original agreement ($18.0 million) and a $3.0 million milestone payment from JT/Torii earned in the first quarter of 2009, and a $3.6 million increase in other revenue primarily related to the settlement of a dispute for $3.5 million.

在净收益的变化主要是由于2008年3月，在研究和开发费用与韩国证券期货交易所，0401（perifosine五百四十〇点〇〇万美元减少到1的研究和有关的发展的Sulonex停止开发费用二千六百九十点〇〇〇万美元减少），在涉及对2007年9月与日本烟草公司和鸟药业有限公司转授权协议，消除了公司的重大，持续的义务的修正案，授权收入二千零八十零点零零零万美元增加原协议中（$ 18.0万美元），由日本烟草300万美元的里程碑付款/鸟赚了2009年第一季度，并在其他收入主要是与一个以350万美元的争端解决三六○○○○○美元增加。

利用坐标变换法证明了一般三维塑性流动问题任意点应力状态，可以完全由三维最大剪应力迹线上的信息确定，进而利用共斜面法给出了三维塑性流动问题沿最大剪应力迹线正应力的变化规律。

Testing in terrain relief, and the algorithms can optimize the structure of TIN nicely.(2) According to the smoothness of the terrain and correlation between adjacency data points, the paper studied the possibility of smooth surface constructing of DEM based on TIN. Then based on Tayor fomula, vertical normal vector, triangular decomposition, continuous and smooth of surface and so on, a new kind of interpolate model of DEM was proposed based on TIN.

2分析原始地形起伏变化的连续光滑性以及邻近数据点之间的相关性，探讨了基于TIN的DEM光滑曲面构造的可行性，并基于二元泰勒公式、三角面剖分、曲面的连续光滑性等，提出了一种TIN上的DEM表面光滑插值模型，并通过构造数学曲面进行精度评估，并对模型进行了可视化分析。

The method of respiratory chamber has been applied to study the influences of water temperature on the oxygen consumption rate,the oxygen consumption and the asphyxiation point in Carassius auratus Triploid.

Some approved aneugens Trip terygiuwlIypogaucum (evelHutch, colchicine, thiabendazole, a tropine sulfate,d-ubocurarine was added into the reactive system respectively and the changes of their absorption values were taken down during different periods under the conditions of 37 0C and 350nm .

本研究通过多步聚合和解聚合反应从猪脑中分离纯化微管蛋白，建立微管蛋白的体外聚合和解聚合反应平衡体系，并将已证实的非整倍体诱发剂（昆明山海棠根部水抽提物、2-（4′-噻唑）苯丙咪唑、硫酸阿托品、d-筒箭毒碱）分别加入此反应平衡体系中，于37℃、350nm条件下，记录此体系不同时期的吸光值变化，与阳性对照物和溶剂对照处理平衡体系后的吸光值在相同时间点作比较，以此评估这几类非整倍体诱发剂对离体条件下的微管蛋白聚合的影响，寻求这几类非整倍体诱发剂是否可通过抑制微管蛋白聚合作用途径而诱发非整倍体。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
