可避免的

Since the varies of gun attitude angle and the vertical vector of the homograph plane are one-to-one, all the elements of modulation gun can be transformed into the calculation of the vertical vector angle, which avoids the calculation accuracy loss of the traditional approach under the condition of the tiny attitude angle disturbance.

由于火炮姿态角变化与相应平面的法向量是一一对应的，从而可将调炮诸元转化为法向量夹角来计算，这样可避免传统方案在微小姿态角扰动情形下导致的计算精度可能的损失。

At the bookish assembly hosted by Secretary General Huang Chin-ying on January 3, Mr. Chang Pei-chen presented the first report on the Secrets of the 17-year Cicada written by Japanese Jin Yoshimura, a specialist of eco-mathematical model and biological evolution. The book was adapted from Yoshimura』s paper published in American Scientist in 1996, exploring the causes of evolution of magicicadas. Based on the duration of dormancy, magicicadas fall into two groups: the 13-year and 17-year periodical cicadas. Based on the principle of the survival of the fittest, as the lowest common multiple was larger, there were fewer groups proliferating at the same time to prevent damage of their ecological regularity as a result of hybridization.

1月3日读书会在黄晋英秘书长主持下，第一篇由张培臣先生报告《17年蝉之谜》，作者为日本人吉村仁，专攻生态数学模型与生物演化理论，本书改写自吉村仁於1996发表於《美国自然学家》期刊的论文，探讨质数蝉的演化缘由；依若虫期蛰伏於土壤中年份的不同，质数蝉大致可分为13年及17年两类，在天择情形下，因为最小公倍数比较大，同一时间的繁殖群相对比较少，可避免杂交而破坏其生态规律。

Surcharging is one of the exsiting ground improvement techniques. It could be used to reduce long term settlement and also used to increase soil strength. But the rebound and recompression properties after surcharge removal are not well established.

超载工法为众多地盘改良工法之一，常被用来改良软弱土壤，不仅可增加土壤的强度，并可避免建物完成后因不均匀的沉陷而衍生问题，但是对於地盘受超载改良后的回胀与再压缩性质一直无法确实的了解。

It is concluded that m = 2 tearing mode is produced by the current gradient. Ifoptimized current gradients are retained in the vicinity of q = 2 singular surface, the disruption can be avoided. There is no need to select current density profile on the whole plasma section.

结果表明这种不稳定性由q=2奇异面附近电流梯度的增大引起，因此只要在奇异面附近保持适当的电流梯度就可避免破裂发生，即对电流分布实行局部控制就可实现对破裂的抑制，并不需要去选取某种特定的整体分布。

In fact using vats of bubble tea, a glass of wine could be the tea, and tea and water to avoid waste.

事实上用大桶茶的泡法，也可得到一杯香醇的茶汤，且可避免茶叶和水的浪费。

Blanch Coke Law: Flower is the woody branches will end on the candle flame, burning 2-3 minutes later, charred squid剪去point Add alcohol immersed one minute, out on the water after rinsing in clean inserted after bottle, flowers in hand to avoid the translocation organizations plug, prevent shear branches I was bacterial infection, has been continuously making flower water supply, extended preservation.

灼焦法：是将木本花卉的枝条末端放在蜡烛的火焰上烧2-3分钟后将烧焦的花枝剪去一点放入酒精中浸泡1分钟，取出后放在清水中漂洗干净后插入瓶中，这样既可避免花枝的输导组织堵塞，又可防止枝条剪口被细菌感染，使花朵不断得到水分供应，延长保鲜。

If the progress of the solvent front is monitored closely, itis also acceptable to draw start and stop lines on the plate before the chromatogram is run (A pencil should be used because ink is soluble). This prevents inaccuracies that occur when the solvent evaporates before the final solvent front can be marked. Sketch the chromatograms in your lab notebook.

如果要密切监测溶剂前沿前进过程，可在进行层析前可以先把起始线和终止线先标上，这方法是可以接受的(应该用铅笔，因为墨水是可溶解的)这样的话可以避免由于溶剂前沿在被作标记前已挥发掉所引起的不准确度。

Therefore, this system efficiently utilizes the low quality heat energy to save lots of energy. Its also applies the harmless sorbent as refrigeration material to avoid the greenhouse effect and avoid destroying ozonosphere caused by conventional cooling methods. So it is accordant with the policies of environmental protection.

该系统有效地利用低品位热能，可节约大量能源，而且采用了对环境无害的吸附质作为制冷剂，可避免传统制冷方式带来的温室效应及对臭氧层的耗散作用，符合了当前的能源和环保政策。

Based on traffic properties analysis in highway network,this paper proposes an inferrence model of OD distribution of highway traffic according to entropy maximisation principle.Being able to infer thoroughly from the effective information and parts of data to update the OD matrix the model can simplify the method of acquisition of OD distribution without over- emphasizing the OD survey as before.

本文在分析公路网交通特性的基础上，根据极大熵原理建立了公路交通量 OD 分布的推断模型，该模型可充分利用各种有效信息和局部资料对 OD 分布情况进行推断及追踪校正，因而可避免严重依赖 OD 调查数据的状况，使获取 OD 分布资料的方法得以简化。
