With the development of digital image enciphering techniques,there appeared a lot of methods including those based on Arnold transformation and affine transformation and those based on theories of Hilbert curve,knight-tour problem,Gray code and etc.However,there are few criteria to measure the merits and demerits of these methods.

随着图像加密技术的发展，出现了各种各样的加密方法，其中有基于Arnold变换、仿射变换、Hilbert曲线、幻方、骑士巡游、Gray码、混沌序列和基于频域的置乱加密技术，但是却缺少一种能有效衡量这些方法的置乱程度及反映加密次数与置乱程度关系的标准。

The key problem for limb , skin or other composite tissues transplantation is to control posttransplantation rejection , which encumbers long term functional survival of transplanted organ and tissues .

作为皮肤复合组织移植的受者，术后出现排斥反应的几率很高，排斥反应发生的程度和频率将直接影响移植组织能否长期存活及功能能否及时恢复，而免疫抑制剂的个体化用药是否合理又直接影响术后免疫排斥反应发生的频率和程度，因此为受者&量体裁衣&制定免疫抑制剂术后个体化给药方案，是保证移植组织或器官有功能性的长期存活的关键因素之一。

The adsorption properties, wetting ability and electrochemical impedance spectrum properties of graphite felts in vanadium electrolyte were investigated.

研究了不同氧化程度下的石墨毡在钒溶液中的吸附性、润湿性及其交流阻抗图谱，结果发现随着氧化程度增加，吸附性和润湿性增强；交流阻抗谱包括两个半圆和一条直线，高频半圆对应离子的吸脱附反应，低频半圆对应电化学反应，直线对应离子在溶液中的扩散过程。

In researching of experiment,this study prove that that fragmentized technology can improve the compressive and tensile strength of pebble concrete .

通过试验研究证明，破碎工艺能改善卵石混凝土的抗压和抗拉强度，对抗压强度的改善程度在10%以内，而对抗拉强度的改善程度可达20%。

In 2003,the index of the landscape fragmentation has rised and the degree of the landscape fragmentation has changed seriously; the landscape of the soll and water loss has developed more and more multiple and fragmentized.

景观斑块个数增加，斑块平均面积出现不同程度的减少，景观斑块平均面积减少了5.7hm^2，景观破碎化指数1987年为0.914，2003年为0.922。破碎化指数增加，景观破碎程度加大。水土流失景观向多元化及破碎化方向发展。

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。

The result shows that: a positive correlation is found between the amount of application of chemical fertilizer and some factors, such as farming hours, attitude towards risks, total family incomes and the proportion of agricultural labour and non-agriculturallabour. A negative correlation is found between the amount of application of chemical fertilizer and other factors, such as farmers' educational background, their cognition of chemical fertilizer, and the channel of information. The agricultural incomes and planting areas seem to be not notable inflecting factors.

研究结果表明：户主的从农时间、风险态度、农户家庭总收入、以及劳力与非农比例情况对农户施肥量成正向相关关系；户主的教育程度、农户对于化肥的认知情况、信息渠道、施肥方式、是否施用有机肥、农户对于化肥利用率的认知以及农户对于污染认知程度等因素对农户施肥量成负向相关关系；农业收入和种植面积的影响则是不显著的。
