白种的

We choose the arid land of northwestern China as our study area because of its extensive area, specific geographical location, dry climate, varied topography, vulnerable ecosystems and long-term human disturbance, as well as the existence of current conflicts between economic development and environmental protection. Based on the literature, we choose ten desert species with clear and relatively accurate geographical distribution ranges to model their distributions:Anabasis brevifolia, Atraphaxis frutescens, Calligonum mon-golicum, Ephedra przewalskii, Gymnocarpos przewalskii, Haloxylon ammodendron, Haloxylon persicum, Ka-lidium cuspidatum, Salsola laricifolia, and Sympegma regelii.

：选择面积广阔、地理位置特殊、气候干旱、地形地貌多样、生态系统脆弱以及人类活动长期干扰，而且目前面临着西部大开发和环境保护双重矛盾的西北干旱区作为研究区域，通过收集西北干旱区多种优势种和常见种的地理分布资料，选取10种分布范围相对明确、资料相对齐备的荒漠植物种：短叶假木贼、木蓼(A- traphaxis frutescens)、沙拐枣、膜果麻黄、裸果木、梭梭柴、白梭梭、尖叶盐爪爪、松叶猪毛菜(Salsola lar- icifolia)和合头草，定量分析其地理分布与气候因子的关系，并据此估测其潜在中心分布区和潜在最大分布范围，与实际分布范围进行比较。

Eurasian plant apple-scented foliage and white-rayed flowers and feathery leaves used medicinally; in some classification systems placed in genus Anthemis.

Clau (5, 10, 20〓) was bound to rat plasma a greater extent than clau, while in rabbit plasma the reverse was the case. By Scatchard plots using bovine serum albumin, clau had a higher equilibrium constant and the greater numbers of binding sites than its antipode.

在与大鼠血浆蛋白的结合中，clau的结合率平均为28.37±0.31（n=3，三个剂量5，10，20μM），clau的结合率平均为38.05±2.61（n=3），clau结合率低于clau；而在与兔血浆蛋白的结合中，clau的结合率平均为47.21±4.91（n=3，三个剂量），clau的结合率平均为41.43±5.21（n=3），clau的结合率略高于clau；在与牛血清白蛋白的结合中，clau的结合率也高于clau，立体选择方向与兔血浆蛋白结合相同，而与大鼠血浆蛋白结合相反，提示存在种属差异；在与系列浓度的牛血清白蛋白结合中，通过Scatchard作图法求得蛋白结合点数和平衡常数；在clau，N和K分别为90.02±35.76和5.326±1.196（n=4）；在clau，N和K分别为59.92±20.39和4.203±1.250（n=4），两者的比值分别为1.50和1.27；进一步说明clau对映体的蛋白结合存在立体选择性差异。

Sampling points were obtained by using optimal Latin hypercube design of experimental method,meantime,in order to improve computing efficiency,application of stepwise regression response surface approximate method in the MDO system of the vehicle crashworthiness and free mode of Body-In-White,the approximate model was optimized by using sequential quadratic programming method.

采用最优拉丁方试验设计方法进行样本数据设计，同时，为了提高计算效率，采用了一种新型的响应面构建方法——逐步回归响应面方法构建了整车耐撞性与白车身自由模态多学科系统的近似模型，利用序列二次规划优化方法对此近似模型进行优化，避免了整车碰撞传统优化设计方法计算量大，在碰撞非线性系统优化中常常易导致收敛缓慢甚至不收敛的缺点，在满足了CMVDR294安全法规的同时，使得白车身的扭转模态值得到提高，汽车重量得到较大程度的减轻。

The thesis calcines process by the fact that the laboratory high temperature Stove simulates the rotary kilns producing ascent K2SO4 adds amounts H3PO4,calcination time and the kiln head calcine the temperature specifically for four kind of the mass affecting a titanium dioxide calcines a parameter mainly, take that white degree, eliminates the color force , PH value and attracts a water yield as main quality index ,adopt the homogeneous sample to follow the parameter having carried out an optimization on specially appointed composition and slanting mass metatitanic acid calcining the best calcination having tested, gaining a group of synthetical quality index.

本论文通过实验室高温炉模拟生产现场回转窑煅烧过程，针对影响钛白质量的四种主要煅烧参数K2SO4加量、H3PO4、煅烧时间和窑头煅烧温度，以白度、消色力、遮盖力和吸油量为主要质量指标，采用均匀是要法对特定组成和质量的偏钛酸进行了优化煅烧试验，获得了一组综合质量指标最好的煅烧参数。
