Therefore it is necessary to research the mechanism of greensand used for high compacted molding methods thoroughly.This subject is one section of the National Natural Science Foundation subject ""Ivestigation on Predicting Method and Mechanism of Springback for High Compacted Sand Molds"", followed of the other completed one named ""Research on Microdeformation of Molding Sand"". A serious of experiments has been done on the reequipped three axial machine under certain technological conditions, and the mechanics, material science, rheologic science. It is systematically studied that the influences on the springback of sand mold were caused by the main influence factors: pressure, compacted rate and the content of soil. Through the analyzed experiments' data, the experienced stress-strain relationship concerning the main influence factors were obtained;under different technical parameter, the springback and spingback's potential energy are compared, the differences and indifferences between them are found out, and the springback's mechanism is discussed;according to the tests' data of YangGuoping coming from Tinghua University, experienced formula of molding sand's springback displacement is induced, the displacement and springback are compared, the margin of error's reasons are analyzed, and they are tested and verified mutually.

本课题为国家自然科学基金项目"高紧实度砂型预测方法及回弹机理的探讨"的一部分，是已结题的国家自然科学基金项目"铸造型砂微变形的研究"的后继，运用力学、材料学及流变学理论，利用改装的三轴仪，在一定的工艺条件下，作了大量系列实验，系统的研究了压实比压、紧实率和膨润土含量对砂型回弹的影响；对实验数据进行了分析和处理，得出了型砂关于压实比压、紧实率和膨润土含量的本构关系的经验公式；把各工艺参数下的型砂产生的回弹量与回弹势能进行比较，找出两者存在的异同点，并对回弹机理进行了探讨；通过清华大学杨国平的实验数据，推导出型砂回弹位移场的经验公式，并与实验测出的回弹量进行比较，分析误差造成的原因，并互相进行了验证。

The results show that under crop rotation of wheat and maize in damp soil and brown soil, stalks return to fields integrated with applying potash fertilizer can keep K balance within a cycle and K return rate reaches 109.1%～111.9%, annual wheat stalks return to fields can provide 226.5～261.0 kg/hm2 K, meanwhile the K return rate reaches 95.2%～97.1% for only applying potash fertilizer; under crop rotation of wheat and soy bean in grittiness black earth, only applying potash fertilizer can also keep K balance within a cycle, its K return rate reaches 119.9%, meanwhile the K return rate reaches 142.0% for stalks return to fields integrated with applying potash fertilizer, which result from maize being much more absorption to K than soy bean.

在砂姜黑土区小麦+大豆轮作制度下，即使小麦秸秆不还田，仅施用化学钾肥，亦能维持小麦-大豆轮作周期钾素的平衡。施钾配合秸秆还田处理，钾归还率达142.0%，施钾且秸秆不还田处理钾归还率达119.9%。主要是大豆不象玉米那样带走较多的钾造成的。

The tartar is a gums various tooth week the harmful germ stirs up a ratio can not little"carry a body", because the gum atrophies, but be disgusted with making oxygen germ can stir up, spread under the gums, hit gum and tooth over a long period of time the week organizes of health;In the meantime such as front say of because of the malnutrition of gum, this eliminates that long under, then cause the adult mouth cavity resist the disease violate of ability, along with age growth but significantly decadent result, thus cause various gum burning, tooth week burning, tooth Sui burning symptom.

牙石是龈下各种牙周有害病菌滋生比不可少的"载体"，由于牙龈萎缩，而令厌氧菌在龈下得以滋生、扩散，长期侵袭着牙龈和牙周组织的健康；同时如前面所说的由于牙龈的营养不良，此消彼长之下，进而导致成年人口腔抵抗疾病侵害的能力，随着年龄增长而大幅衰退的结果，从而引发各种牙龈炎、牙周炎、牙髓炎症状。

Experiment results indicate the more desirable orange-pomace bread can be produced if the orange pomaces are not washed in water, the sample is oven-dried and the particle diameter distribution of the orange pomaces in use is less than 250 μm. Due to the fact that the water-absorption ability of orange pomaces is strong, we may want to mix pomaces with the oil of the recipe first during the process of making orange-pomace bread and add the mixture later to the formation of the structure of gluten. Under the condition that orange pomaces account for 14% of the ingredients, the adjusted optimal condition calls for extra 2% of oil, 3% of water and 4% of gluten, the amount of yeast is increased to 2% and the fermentation time is 2 hours. The orange-pomace bread made under this condition has a specific volume of 5.19 cm3/g and receives a rating of 9.5 point. It is close to the American-style sweat bread of the control group. It is also found that the addition of orange pomaces can help slow down the rise in hardness, gumminess and chewyness of the bread during the time it is in storage.

实验结果显示，柳橙果渣於制备过程不经过清水漂洗、利用烘箱乾燥样品、使用粒径分布尺寸小於250 μm之柳橙果渣对於制作柳橙果渣面包有较理想之结果，另外由於柳橙果渣吸水性强，於制作果渣面包时需将柳橙果渣先与配方中之油脂混合，待面团搅拌成筋后再加入。14%柳橙果渣添加量下，配方上调整的最适条件为额外添加2%油脂、3%水量、4%面筋，并将酵母量增加为2%，发酵时间为2 h，所制作出之柳橙果渣面包比体积为5.19 cm3/g，评分为9.5分，接近控制组美式甜面包，并且发现添加果渣制作面包可以减缓面包於储藏期间硬度、胶性度、咀嚼度上升之程度。

It showed that the halophile of Kenyu7 were better than Wuming-5;(2)the contents of proline of the two Zea mays varieties increased significantly,and under high NaCl stress(150mmol/L NaCl or above) the increasing amount of the contents of proline of Kenyu7 was higher than Wuming-5 ,so it showed that the injuries of Wuming-5 imposed by NaCl stress was greater than Kenyu7;(3)the activities of CAT of the two varieties were no obviously changed,while the activities of CAT of Wuming-5 were all higher than Kenyu7 under all concentrations of NaCl solution,which hadn't showed the correlation between the activity of CAT and salinity tolerance.

结果表明，随NaCl溶液浓度的增加：（1）两品种玉米生长均受到严重抑制，发芽势降低，芽和根的长度均呈减小的趋势，总体来看，杂交种垦玉7的发芽势、芽和根的长势均好于自交系无名-5；（2）两品种玉米体内Pro含量均增加，且在NaCl浓度超过150mmol/L时，杂交种垦玉7体内Pro含量增加的幅度明显大于自交系无名-5，而使垦玉7对盐的适应能力强于无名-5；（3）两品种的CAT活性变化幅度均不大，但无名-5的CAT活性在各NaCl浓度条件下均高于垦玉7，这可能是由品种间本身差异造成的，而与品种的耐盐性无直接关系。
