Hammer shall be dropped freely and stricken the head of hemispheroid steel ball, then take test piece out and check if it fractures.

使重锤自由下落，撞击位于试件表面的冲头，然后将试件取出，检查试件是否穿孔，试验 3 块试件。

In the same way failure area is not single andis more complex with decrease of scale of specimens. And failure shape ismore close to quasi-brittle failure. It varies with homogeneousness that thescale of specimens at which failure shape changes.(3) The failure shape of homogeneous specimens with crack is controlledby crack. But that of heterogeneous specimens with crack is controlled bycrack and heterogeneousness.(4) Acoustic emission doesnt appear until homogeneous specimens fail.

但对于不同均质度，试件破坏形态发生变化的尺度也不同；(3)对于均质度较高的含裂纹试件，试件的破坏形态主要受裂纹控制，而对于均质度较差的含裂纹试件，试件的破坏形态由试件材料的非均匀性和裂纹共同控制；(4)均质度较高的试件，破坏前，试件内不出现声发射，破坏瞬间，声发射在某些部位同时出现，且随尺度增大，试件声发射能量增大，声发射区趋于集中。

The results indicated that (1) the 147Pm, 141Ce and 147Nd had strong adsorptivity in soil, so they were hard to transfer and easily accumulated in soil or sediment;(2) all the organisms (5 aquaties and 4 eatable plants) tested showed apparent 147Pm concentrating capabilities;(3)the residues of 147Pm, 141Ce and 147Nd were unevenly distributed in the animal's viscera and tissues, higher residues were found in bone, marrow, eye, brain, heart, adipose and testis, showing selective accumulation;(4) with intraperitioneal dosing of Nd or Ce 200mg ·kg -1 apparent inhibition to gonadial hormone secretion in mice was found and with 200 and 800mg·-1 of Ce added in feed, the malformation rate of spematozoon showed higher.

综合研究结果表明： 14 7Pm、14 1Ce和14 7Nd在土壤中具有强的吸附性，而且难以迁移，易于在土壤和底泥中积累；( 2 )供试的 5种水生生物、4种陆生食用植物对14 7Pm均具有明显的富集性；( 3) 14 7Pm、14 1Ce、14 7Nd在动物体内脏器和组织间呈不均匀分布，在骨骼、骨髓、眼、大脑、心脏、脂肪和睾丸中残留量较高，表现了明显的选择性蓄积；( 4 )一次性腹腔注射2 0 0mg·kg-1的Ce和Nd对小鼠性腺激素的分泌有明显的抑制作用，以 2 0 0和80 0mg·-1的Ce随饲料摄入对雄性小鼠精子畸形率明显升高。

Ing method. We found, after statisticsing the 91 tested preface classification data′s result, that Stress=0.13481＜0.20,DAF=0.86519＞0.60,and the model draws up to match well and has the certain rationality. Organizational management structure of the Jin-merchant in the Ming and Qing dynasty could be divided into five dimensionali?鄄ties:(1)the form of inspiritment methods is diverse;(2)the personnel system is enlightened;(3)the principle of the personnel selecting is objective and strict;(4)strategic measure of human resource can keep on the develop?

在对91名被试的有序分类数据结果进行统计处理后发现，Stress=0.13481＜0.20，DAF=0.86519＞0.60，表明模型拟合良好，具有一定的合理性，且明清晋商组织管理的结构可分为5个维度：（1）形式多样的激励手段；（2）开明的用人制度；（3）客观严格的选拔理念；（4）可持续发展的人力资源战略措施；（5）严格规范的制度与考核管理。

The paper discusses briefly the differences between testing of CBM well and the conventional oil and gas well in aspects of well testing objects,petrographical structure,level of extraction,well test model and analysis methods of well testing results.

本文从煤层气试井的对象、煤岩结构、开采阶段、试井模型、试井分析方法等方面简要讨论了煤层气试井和常规油气井试井的差别。

For dense grade the saturated-surface-dry method is more correct than the wax-enveloped method if fully soaped. For loose one, the latter is more correct than the former if the wax is not shed and the temperature is not too high. For sample with some holes, covered with talcum powder will be more correct, thus the talcum powder should be required for these ones, and the calculating formula should be amended referring to this paper.

研究结果表明，密级配试件表干法比蜡封法更趋准确，但试件应充分浸水；对于开级配试件，蜡封法结果比表干法更为准确，但要保证水不会由于蜡的脱落而进入试件，同时温度不宜过高；对于表面坑洞较多的试件，加滑石粉可以替代试件的开口空隙而使结果更加准确，故对沥青碎石试件最好强制添加滑石粉，而且计算公式应参考本文推荐公式进行修正。

First make the subjects give either right or wrong responses to the same question with different b value. When estimating the abilities of the subjects with the use of one-parameter or two-parameter Logistic model, it is found that there exists two kinds of unfits.(2) Estimate the abilities of the subjects after introducing c parameter on the basis of the two-parameter model. The first unfit can be rectified. However, the second unfit still exists and the third unfit appears.(3) Then estimate again after introducing y parameter. It is discovered that the second unfit is rectified, but the first unfit still exists and the fourth unfit appears.(4) Form Logistic four-parameter model by introducing c parameter and y parameter at the same time and estimate one more time. This model makes all kinds of unfits, including the first, second, third and fourth unfits, rectified.

1设计这批被试分别做对或做错一道b值不同的试题，用Logistic单、双参数模型对被试进行能力估计时，发现被试能力估计存在着两类失拟现象；(2)在双参数模型基础上增加c参数，对被试进行能力估计，发现c参数能有效纠正第一失拟现象，然而仍然存在第二失拟现象，同时还存在第三失拟现象；(3)在双参数模型基础上增加γ参数，再对被试进行能力估计，发现γ参数能有效纠正第二失拟现象，而仍然存在第一失拟现象，同时还存在第四失拟现象；(4)同时增加c、γ参数形成Logistic四参数模型，再对被试进行能力估计，这时该模型对各类失拟现象，包括第一、第二、第三、第四失拟现象都具有良好拟合能力。

The results showed that two of the ball cactuses tested could growth well in solution culture , in which the growth rate was significantly higher than or equal to that in peatmoss culture. Among the four solution culture formulae , formula 4 had the highest biomass increment and uptake of N , P and Kfor Ferocactu horridus. The biomass of Echinopsis calochlora did not differ significantly among the four formulae , but significantly increased higher than medium culture. This study indicated that ball cactuses could grow well in nutrient solution culture.
