By fitting of experimental data of concrete beams with 2-D composite cracks based on the fictitious crack model, mathematical expressions for parameters α and β in the 2-D composite inteneration equations for Ⅰ-Ⅱ,Ⅰ-Ⅲ, and Ⅱ-Ⅲ composite cracks are obtained, and based on the expressions, 2-D composite inteneration curves under different proportions of two stress intensity factors, that is under different weights, at the ends of 2-D composite cracks can be directly derived.

作者中文名：邵勇；王向东摘要：基于虚拟裂缝模型，通过对混凝土二维复合型裂缝梁试验数据的拟合，得到了ⅠⅡ，ⅠⅢ，ⅡⅢ3种二维复合型软化方程中参数α，β的数学表达式。据此表达式可直接求得二维复合型缝端2个应力强度因子之任意比值下混凝土二维复合型的软化曲线。

It also can be used as the controlling indicators for membrane bio-fouling in the prophase. When the bio-fouling membrane was anatomized, it shows that the bio-fouling membrane are meshy and coupling, whose primary ingredients are organics matter such as albumin, benzene ring, hydroxyl acid, fatty acid and so on, as well as microorganisms such as cocci, bacilli, leaf mold, alga and so on.

微生物污染解剖试验分析表明，严重的微生物污染薄膜成网状粘联结构，分析到的主要成分有白蛋白、苯环类、脂肪酸和芳香烃类等有机物，可观察到的微生物有球菌、杆菌、霉菌和藻类。

Through the preliminary study on the management of the population of Athyrium multidentatum, we found that the community of artificial Larix gmelinii forest has a high value of usage. Planting the population of Athyrium multidentatum may make us to improve the level of intensive management, and through the test this method is available. The population of the spacing in the row of forty cm in the community of Betulla platyphylla forest and the population of the spacing in the row of eighty cm in the community of artificial Larix gmelinii forest have the largest hight, leafstalk diameter and less herb coverage. The foodstuff technology of ferns is backward and the products are less, so we must improve the study on the usage of forest ferns.

通过对猴腿蹄盖蕨种群经营措施的初步研究，我们得出落叶松人工林群落是一个极具开发价值的群落；人工移栽猴蹄盖蕨种群，可提高集约化管理程度，经过试验，方法可行；白桦林群落株距40cm的猴腿蹄盖蕨种群高度、叶柄直径均最大，且杂草盖度较小；落叶松人工林群落株距80cm的猴腿蹄盖蕨种群高度、叶柄直径均最大；蕨菜食品加工技术落后、工艺简单、产品单一，今后应加强研究。

The fatigue life followed the logarithmic normal distribution or the two-parameter Weibull distribution by the probability regression method.

为研究预腐蚀对疲劳寿命的影响，进行30CrMnS iN i2A和LC4CS试件加速预腐蚀不同时间后的成组随机谱下的疲劳试验，采用概率回归方法对预腐蚀疲劳寿命分布特性进行检验，表明可采用对数正态分布和双参数威布尔分布描述疲劳寿命分布特性。

The developed oil and the reference oil are carried out respectively in two Mercury 60 hp out-board engines for 250 h- makefast bench test .

通过研制油和参比油在60 hp水星舷外机的250 h系泊试验结果表明：大连TC-WⅢ舷外机油性能优良，完全可替代进口的TC-WⅢ舷外机油作为"为民"舷外机的专用润滑油。

The experimental results showed that (1) UASB was able to apply on high concentration of malodor organosulfur compounds, and malodor was effectively removed.

试验表明，（1）UASB可承受很高浓度的恶臭物质，并能达到明显的除臭效果，两级串联的效果要优于一级的处理效果。

Both masker and probe were ramped on and off to avoid spectral splatter.

心理物理测量在依据以下情况实行：（1）频率1000赫兹、反应时间20毫秒的探测音其声音位准高于静音临界15分贝(如15分贝的感觉层次)，（2）将反应时间300毫秒的遮蔽音，其位准调整到可听闻试验中75%的探测音(如探测音仍然在其"遮蔽门槛"内)，遮蔽音和探测音两者断断续续地跳动，以避免频谱散射。3。
