Based on the summarizing of the exiting algorithms of the texture mapping and antialiasing, this paper goes deeply into the basic theory and processing of texture mapping. The texture compress algorithm which can satisfy the need of the memory and time is given for the stochastic sampling in the inverse texture mapping; the geometry transformation in the texture mapping are discussed and the concepts of the unitary parametrization and the patch parametrization is proposed, some kinds of the unitary parametrization methods of parametric surfaces and the geometry transformation in the patch parametrization are also presented; in order to solve the aliasing in the parametrization of intermediate surface-sphere in two-part texture mapping, an area-preserving transformation is presented also; to improve the quality of the graph the aliasing in the texture mapping is analyzed from the aspect of signal process, and the modified summed-area tables algorithms is proposed; the distortion of the scanline conversion algorithms under perspective transformation is analyzed and the proper interpolation algorithm is presented so the aliasing problem of the polyhedral object after the unitary parametrization is efficiently solved.

This regional community structure is simple. The shrub layer and the liana layer are undeveloped. The syngenesis time is short.

调查表明该区域群落结构简单，灌木层和层间结构不发达，群落演替时间短。

Scientists have only a vague understanding of this remarkable transition ,when our sense of time expands beyond this morning's feeding and last week's bath,but now they know a bit more:Conor Liston of Harvard University has determined that the beginnings of long--term recall arise between the ninth and the 17th month of a baby's life,coinciding with structural change in the memory--processing regions of the brain.

当我们的时间意识超越了早上的喂饭和上周的洗澡时，科学家们对于这个显著的转变只有模糊的理解，但是现在他们知道的多了一点，Conor Liston of Harvard University 已经断定长期记忆的开始于一个人的第九周至十七周之间，并且伴随着大脑的记忆过程区域的结构性变化。

In order to ensure intelligent landmine group's eflective b lockage for one region for longer time, it is necesong to optimize target distribution of intelligent landmine group. The o ptimization can reduce power consumption of intelliˉ gent landmine group and achieve fluent internal communication within intelligent landmine group.

为了保证利用智能雷群对某区域进行较长时间的有效封锁，须对智能雷群目标分配问题进行优化，以减小智能雷群整体的电量耗损和实现智能雷群内部的良好通信。

However, it reduced as sliding speed increased. Plastic deformation of stainless steel with testing duration followed A logarithmic function.

不锈钢试样在试验过程中的变形量与时间之间存在对数函数关系，且其摩擦中心区域的塑性变形大于端部变形量，其磨损机理以黏着磨损和磨粒磨损为主。

The tensile strength and the elastic modulus were assumed to obey Weibull and logarithmic normal distribution and the other mechanical parameters were taken as constant values in the simulations of three-graded-concrete supported beam. The random aggregate random parameters model was established, which is very close to the actual structure. The results show that the nonlinear behavior of higher homogeneous specimen appears later obviously; the influence of random distribution of elastic modulus on the mechanical character is very little in linear range, while great in nonlinear range; random distribution of tensile strength affects the strength and the damage threshold of concrete obviously.

对三级配混凝土简支梁进行数值模拟时，假定各相材料的抗拉强度和弹性模量服从Weibull、对数正态两种随机分布，其他力学参数取定值，生成和实际结构比较接近的随机骨料随机参数模型，数值模拟结果表明材料均质度较高的试件出现非线性行为的时间要明显滞后于均质度较低的试件；弹性模量分布的随机性对材料线弹性段力学性能的影响极小，而对非线性区域的影响较大；材料强度分布的随机性对混凝土的强度和损伤阈值有较大的影响。

Real life can be widely used for theft, dangerous goods, specific areas of warning, dweller building road lights of control, Specific turn away, through development that remind etc (such as increasing mercury switch etc.), can be used for any vibration alarm, earthquake, without alarm as previously the sort with artificial control method can greatly reduce manpower, and stable and reliable.

Curvilinear calcification suggests an aneurysm but is a less specific finding because it can also occur in craniopharyngiomas and sphenoidal masses. The intense enhancement of the residual lumen is relatively specific, but differentiation from other masses may be difficult on CT scans depending on the timing and degree of vascular enhancement. The MR imaging features are usually diagnostic, although they can be very subtle [2]. Significant signal heterogeneity is seen with T1 hyperintense signal due to subacute thrombus or flow related enhancement. Areas of T2 hypointensity can be seen due to intracellular deoxy or methemoglobin, calcification, or flow void.

线样钙化提示动脉瘤，但不是一个非常特异的征像，因为这也可以见于颅咽管瘤和蝶骨肿瘤，管腔样明显强化更特异些，但是在CT上与其他肿瘤鉴别可能是困难的，因为这取决与增强的时间与血管强化的程度，MR的特征性表现是更具有诊断意义的，即使有时候可能表现的非常细微，在T1上可以看到明显的不同信号成分，这是由于亚急性的血栓或流动相关增强效应，T2序列上可以看到低信号区域，这是由于细胞内脱氧或高铁血红蛋白，钙化，或流空效应。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
