主要原因

Meanwhile, it makes it difficult to apply angle conversion system to practical goniometry curcuit. The paper makes improvement on the fast following-up conversion and proposes a high-precision dynamic goniometer system and a nonlinear high-speed following-up conversion mode based on inductosyn. It analyses the causes contributing to the error and deduces the expression bf the basic goniometry errors caused by output signal inaccuracy, and also puts forward the bounds on error of axis-to-angle converting.

It is because of no any vibration isolation measure adopted to the grinding wheel machine .

针对砂轮机运转所带来的办公楼噪声严重的问题，应用振动测试分析方法，找到了砂轮机未正确采取隔振措施是引起办公楼内严重噪声的主要原因。

The main reasons for the higher efficiency are the elimination of the water pump, the elimination of the water heat exchanger (which is a source of heat losses), and the phase change of the refrigerant in the ground itself, allowing a higher temperature gradient between loop and ground resulting in a higher rate of heat transfer.

为高效率的主要原因是水的泵，水的热交换（这是一个消除热损失的来源），以及本身在地面制冷剂相变，从而使一回路和地面之间的热传递率较高导致较高的温度梯度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
