本文通过不同品种和不同地点的二次旋转回归试验，分别建立了陕农7859、冀麦5418和百泉3039三品种和辉县、武陟、修武三地点的产量、蛋白质和赖氨酸含量三个性状的二次旋转回归数学模型，并通过计算机模拟仿真，分别筛选出了三个品种和三个地点的小麦高产、优质综合农艺措施实施方案，从而为河南小麦的高产优质栽培提供了依据。

Second: Comparetive study of ordinary X-ray film, CT and 3D-CT in the jaws fractures. Ordinary X-ray film, CT and 3D-CT was performed in 61 cases of jaws fractures. The diagnosis of these three imaging methods was compared with each other and with the operation findings. The result shows that the fractures in body and angle part of mandibal could be shown excellently by all these imaging methods. 3D- CT is the best method in showing the mandibular fractures. Ordinary X- ray film is poor, and the accuracy of CT and 3D-CT is similar in showing the macxillary fractures.

二。颌骨骨折的常规X线、CT和三维CT对比研究：通过对61例不同类型的上、下颌骨骨折常规X线、CT和三维CT显示情况的对比分析，同时与手术结果相对照，结果表明对下颌骨体部和角部的骨折三种影像学检查均显示准确；对下颌骨髁状突骨折的显示三维CT优于CT和常规X线；对上颌骨骨折的显示常规X线显示较差，CT和三维CT显示准确率相似。

In correspondence to the functions of the three phase, mathematics teaching is classified into three teaching patterns as theoretical teaching, empirical teaching and practical teaching, so that purposefulness.

三。三教学模式根据数学认知结构构成的三个要素及其相互关联和递进的关系，将数学学习和数学认知结构的形成分为知识习得、能力提高、素质养成三个阶段。

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.

三。选择25例拔除上颌第一双尖牙正畸患者治疗前、后的上颌模型进行三维重建，分别使用第三腭皱近心端局部腭穹隆和腭部对同一患者治疗前、后的数字化模型进行局域重叠，以治疗前后头颅侧位片的 best-fit重叠为评价标准，比较三种方法之间的差异，对应用三维数字化牙颌模型纵向重叠评价正畸治疗前、后的牙齿移动进行探索性研究。

Besides, the derivatives were synthesized successfully by the similar acid binding agent system, such as tris(4-nitrophenyl) thiophosphate, tris(4-toluene)thiophosphate. The derivative of maleic anhydride was synthesized by the simple method, and its yield was above 90%.

采用类似的缚酸剂体系成功地合成了硫代磷酸三(4-硝基苯)酯、硫代磷酸三(4-甲基苯)酯，并用简单的方法合成了硫代磷酸三(4-氨基苯)酯的马来酸酐衍生物——硫代磷酸三(4-马来酸氨基苯)酯，产率达90％以上。

For instance third-grade Iraq qi flickers with herd rushing current prosperous history et al., the similar third grade"s rogue twin three on two brothers, the motorized team arms of east a hillside front four devases the Xiu person group, as well as quite punctures head"s first-grade three person of group tung oil tree island Guang Hai, this city handsome Ming Heshan the original honest 0.1 days, in country divided into rival baroniess lily-of-the-valley high school, came a third grade to transfer the school suddenly to live the rapids valley head to govern.

The separation of tocopherols and tocotrienols by using the method of adsorption chromatography on silica and on silica impregnated with silver nitrate have been discussed. Satisfactory separation could be obtained with argentation column chromatography by eluting batchwise with n-hexane containing increasing amounts of diethyl ether. More than 90% of vitamin E amount in eluate was tocotrienols.

以乙醚正己烷混合溶液为淋洗液，探讨了硅胶柱层析和硝酸银硅胶柱层析分离生育三烯酚和生育酚的效果，结果表明：通过改变淋洗液中乙醚含量可以将生育酚和生育三烯酚大部分分离：硝酸银硅胶柱层析分离生育三烯酚和生育酚的效果明显高于硅胶柱层析，其洗脱液中生育三烯酚可占V〓总量的90％以上，最高达98.47％。

Wanfenghu reservoir has been polluted seriously, and waters are in a severe eutrophication condition. Whether physico-chemical indexes or biological indexes appraisal, it proved that the water quality of Wanfenghu is between IV-V. Wanfenghu contains high TN and TP which are 5 to 6 times of the national standard content, and the quantities construction of phytoplankton communities is deeply disequilibrium, the Cyanophyta and Charophyta occupying overwhelming

万峰湖水库已经受到了严重污染，水体处于严重富营养化状态，其水体中的溶解氧的三季变化范围在2.92-5.3mg·L之间、化学耗氧量三季平均值为34.77 mg·L~(-1)、总氮三季平均值为2.5 mg·L~(-1)、总磷的三季平均值为0.35 mg·L~(-1)、叶绿素a含量的三季平均值为23.64 mg·m~(-3)，以上各指标表明万峰湖水库水体处于Ⅳ-Ⅴ类水质；无论从浮游植物的群落数量上还是浮游植物种类组成上看，蓝藻和绿藻都占绝对优势，而其它各种藻类极少，是典型的蓝-绿藻型水

The glacial rock surface on the independent hill near Laolinkou Daoban was formed in MIS6. The roche moutonnee in the north of Mountain Tuershang was formed in MIS2. Normally , the distance glacial reached is further and the height of glacial is bigger, the scale of ice age is bigger.

根据三组样品所反映的三次冰期来看，形成于倒数第三次冰期的老终垄的保存，以及形成于倒数第二次冰期的冰川擦痕面的存在，说明最近三次冰期的规模由大到小依次为倒数第三次冰期、倒数第二次冰期和末次冰期。
