然而 ，这种方法要受到两个因素的制约：一是增大超声换能器的功率，必然要增大超声换能器的尺寸，这在本身尺寸就很小的油井中是有一定限度的；二是当超声换能器辐射出的超声波的强度过大时，在超声换能器的周围要发生强烈的空化现象，产生大量的气泡，这些气泡将对超声波产生强烈的散射作用，导致超声波的衰减，反而降低超声波在岩层中的传播距离[1] 。

Slide shift fork shaft, mechanical abrasion, such as locking pin is too large, fork bending deformation or face groove with the ring gear grind open.

换档叉轴滑槽、锁销等机件磨蚀过大，拨叉弯曲变形或工作面与齿轮环槽磨旷。

Results show that a combustion technique by increasing upper half counter offsetting auxiliary airs progressively and biasing superheater division panels can eliminate gas imbalance and heat deviation , decrease slagging on furnace and reduce NOx emission effectively.

某300MW 逆时针切向布置燃烧器锅炉在不同二次风反切方式下分隔屏向左偏置一定角度时，炉膛、烟道气流流动特性模型试验和数值模拟的研究结果表明：燃烧器上半部分二次风递增反切分隔屏偏置一定角度的燃烧技术能显著改善烟道偏流现象，可防止过大热偏差引起高温对流受热面超温、爆管，同时能降低炉内燃烧器区域结渣程度、减少NOx 生成，且改造方便、效果明显。
