查询词典 avoids

Accordingly, as catalyst of light oil sweetening,the binuclear cobalt sulfonate phthalocyanine was selected in this paper. Due to the double active centers in a plane, bi-CoSPc not only increases the solubility in alkaline, but also avoids its dimerisation, which expects to increase the catalyst activity in sweetening process.

为此，本文选用双核酞菁钴磺酸盐作为轻质油品脱臭催化剂，该催化剂具有平面双核的分子结构，这不仅增加了其在碱液中的溶解度，同时也减弱了二氧加合物的形成趋势，有望在轻质油品催化氧化脱臭工艺中具有更高的催化活性和使用寿命。

This algorithm provides a smooth transition between the Slow-Start and Congestion Avoidance, which avoids drop multiple packets from a window.

该算法实现了从慢启动到拥塞避免的平滑过渡，减少了在一个窗口中出现多个包丢失的现象。

The paper considers the Dugdale model in elasto-plastic fracture mechanics, and smoothness of the wedge profile, which suppress the stress singularities both at the edges of contact and at the sharp corners. The approach avoids the self-consistent numerical calculations for the real material potential.

研究中运用弹塑性断裂力学中的Dugdalc模型和对冲头尖角的连续化处理，消除了接触区边缘及尖角处的应力奇异性，并避开了自洽问题数值求解的困难，得到了完整的理论公式。

The work of projection from the ellipsoidal surface is not done, which avoids the projection distortion.

由于并未经过从椭球面到平面的投影，从而避免了投影变形。

It avoids the killing and enslavement of animals, and it helps protect the environment.

因为，素食不仅直接避免了动物的杀害和奴役，而且也非常有利于生态保护。

The system of blower performance auto-testing improves the stability of testing process, avoids the error of reading, the error of calculation and the error of result causing by relative dates can not be recorded at the same time, the precision and efficiency of testing is largely improved.

整个系统具有界面友好、操作方便、功能齐全等优点，试验结果表明研制基于虚拟仪器的风机状态自动测试系统，增加了试验过程的稳定性，避免了人为的读数误差、计算误差以及相关数据不能同时记录所引起的试验结果的偏差，提高了测试精度和试验效率。

The measuring method is not subject to limitations of meas uring environment and site and avoids from the error of manual reading, with adv antageous of high precision, easy realization, etc. However, the cost of measuri ng equipment is relatively high.

本测试方案具有测量精度高、容易实现、不受测量环境和场地的限制、排除了人工读取误差等优点，缺点是测量的设备成本相对较高。

Aiming at these problems, an expectation maximum based MAP algorithm is proposed and the performance is analyzed. The proposed algorithm avoids large matrix operations by using the EM algorithm to decompose the MIMO channel estimation problem into a series of single input single output problems. Besides, a joint estimation is carried out over multiple OFDM symbols in order to enhance the data transmission efficiency and the estimative performance of the proposed algorithm.

该算法利用EM算法把多输入输出信道估计问题化简为一系列独立的单输入输出问题，避免了大规模矩阵运算，降低了MAP算法的计算复杂度；为进一步改善MAP算法的数据传输效率及其估计性能，可通过对多个连续的OFDM符号进行联合信道估计。

Because of the ethylenediamine groups on the side chain of BEDAHQA, there is no direct interaction between the chelating group and the fluorophore, which avoids pH sensing.

The engine state is monitored by nonlinear method cooperated with model reference adaptive control, which avoids flameout or fly-off.

对发动机状态进行非线性参考模型自适应监测，可以有效地防止发动机熄火或失速。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
