The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.

Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.

通过改性剂B对粘结剂自硬砂的性能影响试验发现，改性剂B能显著提高粘结剂自硬砂的强度，在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外，但在较高环境温度下，改性剂M均降低粘结剂自硬砂的强度，但是适量的改性剂M有利于改善自硬砂的抗吸湿性，而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显，电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后，在粘结膜裂纹处会形成一种绒毛状物质，该物质对裂纹具有愈合作用，这种绒毛状物质中具有改性剂M中的某种成分，且含量很高，由此说明改性剂M对提高抗吸湿性有利。

结果表明，Fe-25Mn-6Si-7Cr形状记忆合金在含沙多相流中的失效机制主要是泥沙犁削，其损伤抗力因高的局域弹性和高的犁削抗力而优于不锈钢0Cr13Ni5Mo，局域弹性高是其损伤破坏速度效应低和空蚀与泥沙冲刷磨损交互作用小的根本原因。

High copper also can cause the decrease of ATPase activity and membrane fluidity. These revealed that high dose copper destroied function of erythrocytic membrane and cause haematolysis, which may be one of mechanisms of the toxic effect induced by high dose copper.

高铜使红细胞渗透脆性增加，在酸性甘油溶液中的溶血速度(AGLT50)升高，细胞膜ATPase活性降低和膜流动性降低，表明高铜能够破坏红细胞膜的功能，进而使得红细胞发生溶破，这可能是高铜对羊红细胞毒性作用的机制之一。

Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.
