To obtain quadratical convergence, however, strict complementarity condition at the Danskin point was used. The condition is too strict to be satisfied in many practical problems such as discrete semi-infinite minimax problem. Another kind of Newton method for finite minimax problems was presented by E. Polak and, without strict complementarity at the Danskin point, superlinear convergence (of order 3/2) was proven.

Polak等人提出了一种直接求解极大极小问题的二阶收敛的牛顿法，但是为获得二阶收敛速度要求在Danskin点处满足严格互补条件，这个条件太强，很多实际问题尤其是半无限极大极小问题的离散化不满足该条件；他们又给出另外一种牛顿法，在不假设严格互补条件成立的情况下，证明了它的超线性（3/2阶）收敛性。

Lighting is computed at the point using a combination of the normal from the center of the sphere at the point and the density gradient.

Alpha 通道包括密度，通过球心的法向量和斜率可以用来计算出光线位置。

Some metaphysicians contend that the relation between the lump and the statue, on the one hand, and the relation between Tib and Tibbles, on the other, cannot be fully understood in terms of the concepts of parthood and identity, but require a further concept, a non-mereological concept, the concept of "constitution": the pre-existent lump at a certain point in time comes to constitute the statue (or a certain quantity of gold or certain gold atoms that first constituted only the lump come to constitute them both); pre-existent Tib at a certain point in time comes to constitute Tibbles (or certain cat-flesh or certain molecules …).

一些形上学家承认在金块和雕像之间、Tib和Tibbles之间的关系，这些关系不能完全根据"parthood"和" identity"的概念进行理解，而必须要一个进一步的概念，一个non-mereological的概念，"构成"的概念：先在存在的金块在时间中的某个点构成了雕像（或，一定数量的金子或金粒子首先构成了金块，继而构成了这两个。）先在的Tib在某个时间点开始构成了Tibbles（或某些确定的猫肉、粒子等等）。

At last, based on the growth point theory and the institutional transformation' two ness, the paper constructs the compellent and the inductivity economic increasing point in the construction industry, definitions the system term in which the reciprocal transformation could be occurred between the compellent and the inductivity economic increasing point.

本文先从哲学和系统论的角度，辨证地思考了制度变迁的内生问题，提出了制度变迁的二重性、制度供给一般以及制度供给特殊，解释了强制性制度变迁和诱致性制度变迁二者之间的相互转化，然后构建了诱致性经济增长点和强制性增长点，并对两类增长点的转化及其转化的系统条件进行了界定。

An important property of the ROC of the globally optimized fusion system is obtained, that is, the slope of a curve in the ROC at a particular point can be used to determine the decision thresholds at fusion center and all the sensors required to achieve the detection and false alarm probabilities of that point.

5推导出了全局最优化融合系统工作特性曲线的一个重要性质，即根据融合系统检测概率对虚警概率的导数，可以确定使融合系统工作在该工作点所需的融合中心及各部传感器的判决门限。该性质是对单传感器检测系统ROC曲线性质的重要推广，从而丰富了检测融合理论的研究成果。

Suppose that is a point on a surface S with equation F=O and that the partial derivativesand are continuous and not all equal to zero at M, then the tangent plane to surface S at point M is given by

假设是方程所确定的曲面S上的一点，F的偏导数在该点连续且不同时为零，则曲面S在点M的切平面的方程是

在两个弹性部件呈点交联的情况，只要求两个部件在交联点的无阻尼阻抗数据(可由阻抗测试或计算确定)。

Of low strain rate under strain-controlled condition, an overshoot appears at the point and an undershoot at the point .

Since the 1664-point up to now, the average market cost line at approximately 2538 points, this point and also happened to be the lowest point May 25, and very coincidentally, the day also happened to be new shares floodgates day.

自1664点起来至今，市场平均成本线大致在2538点，这个点位也正好是5月25日最低点，而且非常巧合的是，那天也正好是新股开闸日。

The existing Frostbrood Vanquisher spells aren't really proper mount spells and at this point nothing says that we will be able to learn them like normal mounts, even if it wouldn't be very surprising to see a new set of flying mount as a reward for Glory of the Icecrown Raider (25 player) Objectives and rewards are obviously placeholders at this point

已存在的霜育镇压者的法术并不为正常的坐骑法术，就现在而已我们无法保证他是个可学的坐骑，但是我们不排除这将是最新的"冰冠堡：团队高手的荣耀"成就的奖励。任务名和奖励现在为暂命名

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。
