难解决的

He was at once chagrined and embarrassed;he said something lamely and beat a hasty retreat

逃避令人不愉快的现实，沉迷于舒适的幻想，是很难解决任何问题的。

Two problems were solved in numerical calculation, one was that a term of 1/r in Maxwell was divergence in cylindrical center where r=0, another was that the value of optical field at cylindrical center was difficult to decided when the cylindrical center set as a boundary condition in Maxwell equation, So the values of optical field need just calculate from cylindrical center to cylindrical boundary, comparing from cylindrical boundary to cylindrical boundary, near upon half CPU time and RAM saved.

计算中解决了在圆柱中心线上Maxwell方程存在发散项1/r以及用圆柱中心线作为边界条件时，中心线上光场值难确定的问题，因而光场只需从圆柱中心计算到圆柱边界，和以圆柱的两条边做为边界条件比较，节省了将近一半的计算时间和计算机存储空间。

This paper describes detailedly the method used in the software, and gives creative solutions to some difficult problems.

本文具体阐述了所采用的面向对象方法，并在一些较难实现的功能上提出了创新的解决方法。

The best advantage of the method is that it can solve the complex fractional order calculus equation which can hardly be answered by the general calculus knowledge.

该方法最大的优点是能够解决由一般的分数阶微积分知识所不能或是很难求解的复杂分数阶微积分问题，对于分数阶的钱性微积分方程也完全适用。

Overuse has become a problem difficult to manage. Although "quality control" practiced in the past improved accuracy and duplicability of test results somewhat, existing problems are not solved.

5%， 过度服务已成为很难管理的问题，既往推行的&质量控制&工作在一定程度上提高和促进了检验结果的准确性和重复性，但并未解决已存在问题。

Shao Qing points out, on Gu Chujun's problem, too much vimineous need manages clear, manage unluckily again however not clear, who to change to solve these problems very hard euqally, and relevant case already caused very big effect, couplet reachs place must scrupulous.

邵青指出，在顾雏军的问题上，有太多的枝节需要理清，却又偏偏理不清，换了谁都一样很难解决这些问题，而且相关案件已造成很大的影响，联交所不得不小心谨慎。

He'll get much longer sessions and the work will become more interesting every day - longer outruns and more challenging problems to overcome.

训练课的时间大大延长，而且工作的内容每天都变得更加有趣--跑步时间长了，需要解决的问题更难了。

It was discovered that proper amount of Nb could markedly increase the resistivity, and the problem of poling was solved.

实验中发现，适量的Nb掺杂可以显著提高BTO的电阻率，从而材料难极化的问题得以解决。

To throw more fuel on the fire: making games is hard.

更直接的说就是：做游戏很难（这就是我们想解决的问题）。

Autumn is quite pleasant, but winters are cold. Floods are common in November and December, presenting Venetia with one of their most difficult and ongoing problems.

秋天的气候宜人，冬天则寒冷。11月和12月常有水灾，给威尼斯人出了一个既最难解决、又拖延最久的问题。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
