The substitution of triangle: used for conditions inequality proof, when given condition is relatively complex, a variable to use another variable representation, then can consider triangle substitution, the two variables are the same parameters.

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.

研究表明：桉树不同家系间木材物理力学性质和化学组成存在差异；粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异，株间、株内木材材色存在变异；桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异，在同一家系或同一无性系中，株间和株内也存在着相同的变化规律；桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关，侵填体含物越丰富，纹孔附物越多，桉材越容易皱缩；最大瞬间皱缩是能产生更大干燥降等的临界点，在制定干燥工艺时，必须在最大瞬间皱缩发生时，采用温和条件，使已产生最大瞬间皱缩的细胞尽可能多的恢复，尤其不能使其产生永久变定；在常温条件下，影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量；而对于瞬间皱缩和最大瞬间皱缩，几乎所有细胞都参与它们的形成过程；对于易皱缩的桉树木材，间歇干燥是最有前途的干燥方法。

Moreover, classical multigrid methods, such as W-cycle and Variable V-cycle, are shown to be convergent uniformly for this mortar type TRUNC element.

我们还用经典多重网格方法（可变的V-循环、W-循环）求解带mortar条件的TRUNC元解，证明所构造的网格转移算子满足收敛性条件，从而传统多重网格方法作预处理的条件数为一致有界。

System of calculation of number of boxes of spars for mechanic was improved, and now many factors will be taken into consideration: price, uniqueness, condition (if the item is in very poor condition you'll receive fewer points, if good - more points, and if the average - the usual number of points ), and presence of the SGM achievement "Mechanic Assistant".

数字系统的计算对机械进行了改进棒材的盒子，现在有很多因素需要考虑：价格，独特性，条件（如果该项目在十分恶劣的条件是你将获得较少的点，如果好-更多的积分，如果平均-通常的积分数），新成就"技工助手"

Should either of the parties of the contract be prevented from executing the contract by force majeure, such as earthquake, typhoon, flood, fire and war and other unforeseen events, and their happenings and consequences are unpreventable and unavoidable, the presented party shall notify the other party by a written notice without any delay, and within 15 days thereafter provide the detailed information of the events and a valid document for evidence issued by the relevant public notary organization for explaining the reason of its inability to execute or delay the execution of all or part of the contract.

该句子的英译文在表达原文内容上是没什么问题的，但是将句中的"解除合同"译成to terminate the contract有些不妥。因为，从法律意义上讲，to terminate the contract是指"终止合同"，而"终止合同"的法律行为，必须在出现了终止合同的法律事件后才能实行。按照《中华人民共和国合同法》的规定，"终止合同"的法定情形有七种（见《中华人民共和国合同法》第91条）。该条款主要说明的是，由于不可抗力事件'致使合同无法履行，这种事由不属于终止合同的条件，而属解除合同的条件。
