Fluidization and Sounding Pressure Characters Experimental Research on Pulsating Fluidized Bed After verifying experimentally the Rijke type self-exciting pulsating fluidized bed combustion, under different operating conditions (different empty cross-section wind speed and inaction bed height), experimental research the oscillation characters of sounding pressure in the pulsating fluidized bed. The results indicate that the sound characters in the Rijke type self-exciting pulsating fluidized bed combustor are the same with it in the Rijke type combustor, the pressure in the combustor oscillate up and down in the sinusoidal manner and the pressure is the superposition of the multiple harmonic waves.

脉动流化床流化与声学压力特性实验研究在实验验证了Rijke型自激脉动流化燃烧概念后，在不同运行条件(空截面风速、静止床层高度)下，实验研究了Rijke型自激式脉动流化床的声压振动特性，研究结果表明：脉动流化床内建立起的声波特性和Rijke型脉动燃烧器内的一样，各点压力呈正弦规律上下振动，且压力是基波幅值最大的多次谐波的叠加。

Little details of nature can send me shivers all the way up my spine and capture me in great joys: the delicate and fragile fresh yellow buds expanding in the chilly wind of early spring, the dew-bearing silvery hairs of a leaf shining in the sunlight of a summer morning, the red-capped flowering stalks of moss in the late summer, the flagging fluffy tail of a frolicking squirrel on the lawn in the fall, the foot prints of all kinds of animals in the snow, and the eager steps of early returning geese on the surface of thawing ice.

自然界的一些微小细节，可以给我带来透澈脊梁的震撼和极大的欢乐：在初春陡峭的寒冷中不断膨胀的精致而脆弱的鲜黄色的芽，夏日清晨的阳光下小草叶尖细细的银白色毛发上闪亮的露珠，夏末顶端戴红的苔鲜的嫩茎，秋季在草坪嬉戏的松鼠竖起的蓬松尾巴，冬天里雪地上清晰的各种动物的脚印，还有过早回飞的大雁在欲化还凝的冰面上渴望的脚步。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
