By using of dynamic fuzzy group method, the top coal cavability was evaluated according to the following seven factors, such as coal seam strength, mining depth, crack developing extent's features, dirt band height, filling situation of goaf, classification of main roof and the ratio of mining and caving height etc.

运用动态模糊聚类方法，以煤层强度、赋存深度、节理裂隙发育程度、夹矸厚度、采空区充满程度、老顶级别、采放比等7个因素按模糊最大隶属度原则综合评价顶煤冒放性。建立了模糊聚分析方法的数学模型，以上述7个指标为基础，对顶煤冒放性的模糊聚类分析进行运算，给出分类的实施过程。潞安矿区顶煤冒放性分类结果表明， 5对主要生产矿井主采3号煤层，其顶煤冒放性皆为好和较好，经潞安矿区综放开采实践证实，分类合理

By evaluating the stability parameters such as the upper wall thickness,solidness and the strength of the mine props,etc,dangerous area of the goafs are predicted. Practical and economic protection measures are proposed ...

针对采空区的顶板厚度、稳固性、矿柱强度等稳定性参数，预测了采空区危险地段，建议对采空区采取监测、封闭、排水、充填、联合支护等既安全又经济可行的防治措施。

Collect by hand : Include direct hand to pick, hook ／ small scissors is collected cut and clipper closes pick 3 kinds of way.

手工采：包含直接手摘。镰刀／小剪刀采割和大剪刀收采三种方式。

And then the designing process and method of the system are expatiated, including the analysis of the system performance, functional module partition, equipment selection and installation, dynamic real-time image acquisition, defect detection arithmetic, and so on. It is worth mentioning that, we have creatively achieve to capture the dynamic images of blood lancets automatically, and we have designed a simple but effective arithmetic for detecting defects according to the image features of blood lancets. Finally, we analyse the experimental results and evaluate the system performent.

在系统设计的过程中，创造性地实现了动态图像的自动采集，对采血针图像的特征进行了有效的分析，采用图像裁剪、直方图均衡化的图像增强方法、邻域平均法的平滑处理方法、基于迭代法自动确定阈值的图像分割方法等对采血针图像进行预处理，根据采血针缺陷的形状特征设计了简单易行精度较高的缺陷检测算法。

Because protein synthesis costs energy while protein canalso be used as a source of available energy,there is an interaction during growthbetween the utilization of dietary protein-free energy and protein.

在自由采食量的预测方面，提出了用累计采食能量对时间进行多项式拟合的方法。该方法可以避免预测自由采食量时的系统偏差，并可应用到对模型的调试和验证中去。

For the understanding of the kinetic variation and distribution of Cl in tobacco area soil of upland yellow-red earth in South Anhui ,soil samples were collected in 4 times of tobacco growth :early winter of 2002,before transplanting in next year, beginning midway, and leaf collecting .

通过对皖南旱地黄红壤烟区进行施Cl处理，施Cl后分别在初冬、次年移栽前、采烤开始、采烤中期、采烤结束后，分五次分别挖土壤剖面取土样；每次剖面层分别取0-20cm、20-40cm、40-60cm、60-80cm的土层土样，同一层同时取4-5点混匀作为一个样品，分析土壤Cl的动态变化。

By taking body-life as the criterion to re-estimate all value,Nietzsche overturned the whole western system of metaphysics,and called in question western speculative aesthetics.

尼采以&肉体——生命&为尺度重估一切价值，颠覆了西方的整个形而上学体系，也对西方的思辨美学提出了质疑，尼采主张应从&肉体——生命&的角度重新研究美和艺术对于人生的意义，尼采认为承担这一研究的学科应当是美学生理学。

By investigation the operatinq courses of taking blood,isolating plasma,and re-turn transfusion of blood cells at local plasmapheresis centers,Cross-contaimination of bloodwere found.and it was the main cause of HCV infection of malaria cases.

对当地单采浆血站进行调查，发现在采血、分离血浆和血细胞还输过程中存在血液交叉污染，这是导致有单采浆史的疟疾病例HCV感染的主要原因。

Although effects of nitrogen fertilizer on nitrogen accumulation and nitrate reductase in tobacco leaf had been extensively studied, impacts of nitrogen fertilizer on flue-cured tobacco leaf nitrogen metabolism in dry land and paddy field were not well documented.

试验采用裂区设计，以硝态氮和铵态氮两种氮素形态为主处理、5个供氮水平为副处理，在大田条件下研究了水田与旱地烤烟在团棵、旺长、脚叶采烤、腰叶采烤和顶叶采烤等5个生育期烟叶的总氮浓度、硝酸还原酶和谷酰胺合成酶活性的氮肥效应。

The text obtains some data that caving span of immediate roof is 30m, caving span of main roof at first weighting is 42m and caving span of main roof at periodic weighting is 14m. Mining influence range is determined about 40m through numerical modeling, namely about three advance pillars were in the range of mining influence.

利用数值模拟得出煤柱采场直接顶的垮落步距为30m，老顶的初次来压步距为42m，老顶的周期来压步距为14m；通过模拟超前支承压力，确定了采动影响范围约为40m，即采场超前的三个煤柱都在影响之内。

At the rear was an innovative combination transaxle with the gearbox, clutch, differential, and inboard-mounted drum brakes.

在后面是与变速箱，离合器，差的创新结合变速，和内侧安装鼓式制动器。
