In order to study the intake air flow characteristics in four-valve diesel engines, in this dissertation hot-wire anemometer and PIV twodimension instantaneous measuring technique are used. Extensive experimental study on two intake valve exit flow fields and longitudinal section flow field in cylinder are performed for different type of diesel engines. Great researching progress have been made on the interaction between two intake ports, and the formation process of in-cylinder swirl and flow field structure of cross and longitudinal section for four valve diesel engines. These results are presented in China for the first time and without such kind of research work reported abroad as detailed and deepgoing as this dissertation. The author designs and makes a set of hot wire measuring velocity device to measure the velocity distribution around the intake valve annulus and the cross section flow field in cylinder.

为了研究四气门柴油机进气过程中气体流动的变化规律，本文利用热线测速和PIV二维瞬态测速技术，对四气门柴油机两进气门出口全圆周流速场和缸内横、纵剖面的气体流动流场进行了大量的试验研究，在四气门柴油机两进气道之间相互影响的变化规律，缸内涡流的形成过程及缸内横、纵剖面流场结构等方面取得了重大的研究进展，这一研究工作在国内尚属首次，在国外也未见有如此全面、深入的研究报道。

In this thesis, the studies for the formation, recovery and application of engine waste heat are emphasized, and the construction of engine-driven hybrid air conditioning system for Shanghai is given for the first time.

Therefore liquid CO_2 avoids gas-solid multiphase flow, and supplies continuous low temperature gas for cryoprobe. Experimental results show that the 2-dimension temperature distribution for the first time, it includes:(1) The cooling velocity and freezing zone increases along the flux up at certain size of the cryoprobe in the same biological tissue.(2) As the diameter of cryoprobe increases, the temperature will descend faster, freezing zone will be broader obviously, and ice ball become larger. Until it arrives heat balance, the temperature keeps invariability.(3) Single freezing-thaw results in biggish mechanical injury already for loosen tissue such as pork liver; Successive freeze-thaw circle could quicken freezing and thaw velocity for compact tissue, and it has proved the more mechanical injury of successive freeze-thaw circle than the single freezing-thaw treatment.

文中首次对生物组织进行了二维温度场分布实验研究，得出：(1)当刀头大小一定，对同一组织冷冻时，流量越大，降温速度越快，降温影响区域越大；(2)随着冷刀直径的增加，降温速度随着增加；温度影响区域明显增大；冰球直径也随着增大，热量平衡后温度几乎不随时间变化；(3)对于结构疏松组织比如猪肺脏，单次冻融对组织已造成较大的机械破损；对于结构较致密组织，多次反复冻融可以使降温和复温速率增加，单次冻融的热应力造成的机械破损较小，多次冻融后造成的机械破损比单次冻融所造成的机械破损大；(4)直喷式刀头比导热式节能约15％。

For the first time in his career, Will has turned his attention to the human voice, working with singers from around the world to create a whole new idiom of music, much as he did in creating Windham Hill's sound in 1976.The impetus for HEARING VOICES actually harkens back to 1998 when Will teamed with Ugandan singer Samite for a track on the album, SOUND OF WIND DRIVEN RAIN.

如同他1976 年创立& Windham Hill之声&一样，作为他职业生涯中的首次尝试，他已将注意力转向人类的声音，他与来自世界各地的歌手合作，创造出一个全新的音乐风格。1998年Will和乌干达歌手Samite合作录制了专辑《Sound of wind driven rain疾风暴雨之音》，此举大大推进了名为&Hearing Voices&的特色音乐。
