起微波

In the acylation reaction between anisole with acetyl chloride, The catalyst of ZnCl〓/HY-98 prepared by MWI had the best catalytic activity and the selectivity of p-methoxy acetopheone. The catalytic active centers were ZnCl〓 dispersed in zeolite and the Bronsted acid sites in HY-98 zeolite itself.

在苯甲醚与乙酰氯的酰化反应中，微波固相法制备的ZnCl〓／Y催化剂有相对较好的催化活性和选择性，起催化作用的主要是分散在分子筛表面的ZnCl〓和分子筛本身的B酸。

A dr. sharp, a project pandora researcher for the us army, ran experiments whereby the human brain picked up words that were transmitted via microwaves, thus bypassing the ear. dr james lin of wayne state university discusses the possibilities of using such techniques to aid the deaf, but comments;"the capability of communicating directly with humans by pulsed microwaves is obviously not limited to the field of therapeutic medicine."

一个夏普公司的博士，一个美国军方的潘多拉计划的研究者，进行了试验，人脑拾起单词，那是通过微波传输的，因此，是不通过耳朵的。wayne 州立大学的james lin博士讨论了用这样的技术帮助聋子的可能性，但评论到，直接通过脉冲微波与人类直接交流在治疗医学领域是明显没有限制的。

Broad bands of rosy gold, as if daubed on with a gigantic brush, stretched across the dark, blue tinted fields; here and there shreds of fluffy, transparent clouds gleamed whitely, and the freshest and most enchanting of breezes barely stirred the surface of the grass, gentle as sea waves, and softly touched the cheek.

Microwave guideline in effect in 1970 for the public, 10,000 microwatts/^2 (now the industrial and military "guideline"), is proscribed from consideration of the rate that thermal effects are dissipated, the author, a specialist in modeling neural networks, states that scientific studies have consistently shown that humans exhibit behavioral disturbances when subjected to non-thermal levels of microwaves, well below this level.

The following main results are obtained: The TiO_2 photocatalyst with small crystallite size, high surface area, narrow and uniform pore size distribution, and microporous frameworks could be prepared out by applying MW radiation in the preparation process. The microwave-induced fluorescence technique verified for the first time that microwave enhanced the formation rate of hydroxyl radical, leading to the increase in the photocatalytic efficiency. Compared with the conventional catalyst, TiO_2 prepared by MW dielectric heating owns a higher UV absorption ability, and its optical absorption edge and photovoltaic response are shifted toward the short wavelength region, resulting in increase of photooxidation efficiency. The photocatalytic conversion and the mineralization ratio of acetaldehyde are increased respectively by 30% and 40% over the TiO2 prepared by MW radiation when compared to the TiO2 prepared by the conventional heating. For the MW-assisted photocatalytic reaction over the MW-prepared TiO2, production of hydroxyl radicals is enhanced by 22.5%, and the photocatalytic conversion is accordingly increased by 20%. Similarlly, applying MW also increased the photocatalytic conversion and the mineralization ratio of acetaldehyde over TiO2/Al2O3 sample.
