It is found that, compared with the vacuum sintering, the magnet sintering at argon protection has lower density, magnetic-energy product and remanence, but coerciveforces are higher. The magnet has more and bigger pores, and there obviously exist loose microstructure, the Nd-rich phases are clearly distributed along the grain boundaries mainly in the shape of lumpish and lamelliform.

研究发现，与真空烧结相比，采用Ar保护烧结时磁体的密度、磁能积和剩磁相对较低，矫顽力较高，磁体中形成的孔洞较多，孔径较大，并有明显的显微缩松存在，富Nd相的数量明显较多，且主要呈块状和片状沿晶界分布。

The advantages and limitations of every kind of methods for calculating the failure probability is reviewed. The frist order reliability method, the second order reliability method and many kinds of boundary method have achieved remarkable success and formed nature fields of reliability. However, the precision of these methods decrease as the increase of complexity of problem. The numrical methods are versatile, except numerical intergration is only adaptable to special problems which have small number variables and regular intergral domain. Particularly, the advanced variance reduction techniques own the following character: high precision and a small amount computation. But some questions remain to study in the future because only an initial work about these techniqes is developed.

全面评述了计算失效概率各种方法的优点和局限性，其中经典的解析法包括一次可靠性方法、二次可靠性方法、一阶边界法、Vanmarcke上边界、PENT上边界和Ditlevsen二阶窄边界法，这些方法对于多设计点、变量较多且相关、密度函数不是正态以及极限状态方程较复杂的情况，其计算精度较差；而已有的数值方法却是具有较好的通用性，其中除数值积分法只对变量较少、积分域较规则的特殊问题适用外，各种数值模拟方法均具有较广的适应性，特别是各种改进的方差减小技术，精度高、计算量小，但由于其处在研究的初级阶段，还有许多问题有待于解决。

Healthy spikes of high-resistant varieties had thicker cell wall and tissue of cortical sclerenchyma, more number of cortical sclerenchyma layers, more number of fibrovascular bundles, smaller area of green subcutaneous tissue in rachis, and theses differences, except number of fibrovascular bundles, enlarged over time. Considering inoculated spikes, cell wall and tissue layers of cortical sclerenchyma displayed different, and to how much extent the relationship between this difference and anti-extension ability of variety had not determined. 6. On the analysis of agronomical characters and molecular marking technology, more than 30 alien anti-Gibberella wheat materials and two mutants coming from this experiment were evaluated their hereditary multiplicity.

实验结果还证明，高抗品种和感病品种的穗轴组织结构确实存在一定差异，在健康穗中，主要表现在高抗品种的皮层厚壁细胞壁和皮层厚壁组织较厚，皮层厚壁细胞层数较多，维管束数目较多，穗轴表皮下绿色组织面积较小，抗、感品种间的差异达显著水平，随发育时间延长，高抗品种的皮层厚壁细胞壁厚度、厚壁组织厚度和厚壁细胞层数增加的幅度较大；在病穗中，主要表现在高抗品种的皮层厚壁组织细胞层数和厚壁细胞壁厚度增加的幅度较大。

Arsenic could be detected in the main organs and tissues of rats after administration of a single dose. The arsenic was most accumulated in the spleen, hair, lung and suprarenal gland organs, and kidney, heart, liver, bladder and skin came next. Brain, testis, muscle and tibia had the least amount of arsenic. After 15 continuous days of administration, arsenic contents in kidney and bladder tissues increased appreciably besides suprarenal gland, lung, hair and spleen.

单次给药后，在大鼠各主要脏器、组织中均可检测到砷，以脾、毛发、肺和肾上腺中分布较多，肾、心、肝、膀胱、皮肤次之；大脑、睾丸、肌肉、胫骨中分布较少，多次给药后砷除了同样在肾上腺、肺、毛发和脾分布较多外，在肾和膀胱的积累显著增加。

That if the process can produce much liquid phase during the sintering, and which can become into completely-crystal needle-shap or aborization or bar-shap calcium ferrite instead of glass in the cooling process; if the magnetite is interweaved by the caking into the melting corrosion structure, the granular structure or the eutectic structure instead of exiling in the massive isolation; if the mount of the poreis is little, and uniformitly distributing; if the grain is little; if the organizational structure is symmetrical, all of which can improve the quality of the sintering.

另外还归纳出有利于强度提高的工艺参数和操作制度。分析工业试验和水钢现行生产的矿物组成、结构表明，水钢烧结矿以他形晶磁铁矿为主，铁酸钙为主要的粘结相，多形成熔蚀结构、粒状结构和共晶结构，强度较高；而在台车边缘和表层，由于存在较严重边缘效应和点火温度较低，使该区域的烧结矿组织结构疏松，局部呈蜂窝状或薄壁大孔状，铁酸钙较少而硅酸二钙和玻璃质较多，形成骸晶状结构和磁铁矿连晶，强度较低，致使返矿升高。

The average of quality of life is 52.98 ± 11.87. The quality of life among Lizu elderly people is not enough high. There may be considered three reasons. Firstly, chronics are very popular in local area. The chronics greatly influence the health of Lizu elderly people and reduce their physiology functions. Secondly, education degree affects the health of Lizu elderly people. Most of Lizu elderly people are illiteracies (76.5%), and they lack the consciousness of self-health care. Thirdly, most of Lizu people have a big family. Children couldnt spend enough time to attend their parents. Local economic income is relatively low and lead to the low level quality of life. 3.13 main factors that may affect the quality of life were analyzed by analysis of variance and T-test.

考虑是该地区黎族老年人患有慢性病人数较多，慢性病患病率高，长期受疾病的侵扰，生理机能衰退，也可能是黎族老年人文盲率较高(76.5％)，文化程度较低，自我保健意识较弱，也可能是黎族同胞传统的大家庭结构，造成家庭人口数多，家庭经济负担重，子女照料老年人时间较少，导致黎族老年人生命质量不高。3、用t检验和F检验对可能影响黎族老年人生命质量的13个因素进行分析，这些因素包括性别、年龄、文化程度、婚姻状况、生活来源、经济状况、医疗费用负担形式、是否患有慢性病、家庭结构、吸烟、饮酒、居住环境、生活满意度。

All of the four plant types (forbs, graminoids, woody plants and forbs) were taken year-round with no significant differences, even though they were varied among seasons, however all types except woody plants showed significant variation among seasons.

獐在冬天较多选择木本植物，而其它季节较多选择草本植物，但木本植物和非禾草类草本植物在四季食物组成中均占较高比例，而禾草类植物所占的比例很小。

The results indicated that the highest yield of BOC-indigo was 97% in CH2Cl2, and the lowest one was in PGMEA. It showed that the yield of BOC-indigo increased with high polarity and low molecular volume of solvent.

从实验结果得知，以极性较强且分子体积较小的二氯甲烷作为反应溶剂，其合成隐性颜料产率可达到97.2%，较四氢呋喃产率多4.4%，且较丙二醇甲醚乙酸酯产率多7.4%。
