易发生变化的

We do have a flight spare that we could practice with, but we know from our experience with the cometary aerogel that it has changed somewhat in space; it has become more brittle .

我们确实有大量可供练习的备用品，但是我们从彗星尘埃的凝胶那里得到的经验是：凝胶在太空里发生了一些变化，变得更加易碎了。

In order to deep holding the engineering characteristic of the coarse-grained soil, this paper researched object that is the coarse-grained soil of the diametre from 0.1mm to 20mm that was often applied in the dam body filter structure, using the experiment method, carrying out the experiment the research of the coarse-grained soil permeability characteristic.

粗粒土在水力作用下，是一种结构极不稳定的土体，在渗流作用下极易发生渗透变形，容易引起坝体的渗透变形破坏。从渗透系数的变化上分析，其渗透变形过程是一个连续的过程，土体的破坏形式大都属于管涌破坏，破坏坡降较小，一般破坏坡降都小于2.5，有的甚至小于1.0。

Have changed and times have changed, and now I am into thesunset, with the changes of the times have changed, more tears up,no more a child that looks like a hero, ha ha, but not the old manin tears ah.

世易时移，如今走进夕阳的我，随着时代的变化也发生了变化，眼泪多了起来，再也没有小时候那英雄模样了，哈哈，但可不是老泪纵横啊。

During the accident, the main steam pressure drops rapidly, the current and outlet temperature of pulverizer become abnormal.

明确了主蒸汽压力快速下降和磨煤机电流、出口温度异常变化是该类型事故的主要现象，指出石子煤冲洗系统冲洗水采用母管制和系统相关阀门工作环境恶劣造成阀门易磨损卡涩是导致磨煤机进水事故发生的根本原因。

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。

Although Pseudodactylogrus bini disease of European eel also occurred in winter, it mainly occurred in the end of spring, summer and the beginning of autumn when water temperature was above 26°C.

该病尽管在冬季也有发生，但水温在26°C以上的春末、夏季和秋初是最易发病的流行季节，流行出现明显的季节性变化。

The analysis of Vp and Vs sectional data of earthquake distribution suggests that the earthquakes are often centralized in the intersectant zones of faults with velocity change zone and faults with faults.

地震分布的Vp和Vs剖面资料的研究暗示，断裂与速度变化带、断裂与断裂的相交区域是地震易发生区域。

Process in the jasmine flower tea foundation in green tea but, especially the high class jasmine spends in process of process certain physics and chemistry in occurrence in quality in its inside function, such as:The polyphenol material in the tea, tea is single rather under the water the wet term of decomposition, do not dissolve to decline the solution in the aqueous protein amino acids, can die down that drink the hour of green tea feels, the function has the variety, the fresh and thick in its taste is thick and alter fluently, this is also a north to like to drink the jasmine flower tea causal a.

茉莉花茶在绿茶的基础上加工而成，特别是高级茉莉花在加工的过程中其内质发生一定的理化作用，如：茶叶中的多酚类物质、茶单宁在水湿条件下的分解，不溶于水的蛋白质降解成氨基酸，能减弱喝绿茶时的涩感，功能有所变化，其滋味鲜浓醇厚、更易上口，这也是北方喜爱喝茉莉花茶的原因的之一。

The three decades that spanned either side of 1800 (from the American revolution to the succession of the French citizen-king, Louis- Philippe) saw tumultuous change on both sides of the Atlantic.

18世纪70年代到19世纪30年代（从美国革命到法国&平民国王&路易·菲利普的继任），大西洋两岸均发生了令人眼花缭乱的变化。

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