3. considering the shortcomings of hydrosoluble - cyclodextrin polymer, such as easily water - absorbed properties and poor endurance in a high electric field, two - cyclodextrin - starch resin electrorheological particles ( wss - - cdp and cls - - cdp ) were synthesized by copolymerization through a mixture of - cyclodextrin and epichlorohydrin in the presence of water - soluble and water - insoluble starch, respectively. the structures of these polymers were characterized by ft - ir and raman s
在4kv / mm直流電場作用下，由可溶性澱粉參與共聚的p一環糊精樹脂電流變液的屈服應力可達6 . 2kpa ，與不含澱粉的p一環糊精聚合物相比，約增加了35 % ，抗電場能力也可增至5kv / mm以上，且持續時間較長。 -
Conventional building - mortar is usually blent into in the construction local, which possesses many defects such as low accuracy of mixture ratio, poor stability of quality, contractility of bigness, broad fluctuation of felted strength, anti - penetrability of feebleness, collapse of easiness and ect, and it is vital reason, resulting in lots of engineering quality accidents as following : crack in the wall, swelling, penetration, and collapse. mortar made in the local is at the cost of wasting materials and contaminating environment
傳統的建築砂漿都是在施工現場拌制，現場拌制的砂漿各組分計量準確度低、質量穩定性差、收縮性大、粘結強度波動大、抗滲性差、易剝落，是建築工程墻面開裂、起殼、滲漏、甚至墻體倒塌等質量事故發生的主要原因；現場拌制砂漿還會造成材料浪費和污染施工環境。 -
The field emission property of carbon nanotubes could be increased by substitution of nitrogen for some of carbon, however, however, that of bcn nanotubes was poor. 1. study of disordered multi - wall carbon nanotube carbon nanotubes with different diameter distributions have been produced by thermal decomposition of a ferrocene - xylene mixture under different temperatures and different catalysts in an ar ( or n2 ) / h2 atmosphere
結合透射電鏡、掃描電鏡及拉曼光譜，系統地研究了以鈷二茂鐵為催化劑時不同溫度下、以及在860時，分別以鈷二茂鐵、鎳二茂鐵、鈷、鎳鈷不同催化劑、不同保護氣體對高溫熱解法制備的多壁碳納米管結構、產率等的影響，對產物的形態、結構進行分析。
