篇7：Size distribution and element compos
Size distribution and element composition of dust aerosol in Chinese Otindag Sandland
Abstract：Part physical and chemical characteristics of dust aerosol were determined for samples collected from Otindag Sandland of China in spring, . Number concentration, mass concentration, chemical element concentration and size distribution of aerosol particles with 0.5 -m < Dp < 100.0 -m were examined. The average number and mass concentrations of aerosols were 274.8 cm-3 and 0.54 mg/m3 for the field period respectively, and 31.4 cm-3 and 0.07 mg/m3 for the non-dusty days. PM10 played a dominant role in the aerosol mass concentrations. The particles with Dp < 8.0 -m accounted for about 93.7% of total aerosol number loading in dusty days. The particle size distributions of aerosols were characterized by bi-modal logarithm normal function in heavy and moderate dusty days, and mono-modal in windblown and non-dusty days. Crustal elements such as Al, Fe, etc. in aerosols almost originated from soils. Pollutant elements of S, Pb, etc. associated with aerosols were affected by remote anthropogenic pollutant sources in upwind regions. Mo, V and Co in aerosols were possibly from other dust sources other than local soils. The aerosols over Otindag Sandland consisted of particles from local soils, upwind pollutant sources and other dust sources.作 者：CHENG Tiantao U Daren CHEN Hongbin WANG Gengchen 作者单位：CHENG Tiantao(Department of Environmental Science and Engineering, Fudan University, Shanghai 33, China)U Daren,CHEN Hongbin,WANG Gengchen(Division of Middle Atmosphere and Remote Sounding Theory and Technology, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China)

Identification of pore size in porous SiO2 thin film by positron annihilation
Positron annihilation lifetime and Doppler broadening of annihilation line techniques have been used to obtain information about the small pore structure and size of porous SiO2 thin film produced by sputtered A1-Si thin film and etched Al-Si thin film. The film is prepared by an Al/Si 75:25 at.-% (A175Si25) target with the radiofrequency (RF) power of 66 W at room temperature. A 5 wt.-% phosphoric acid solution is used to etch the A1 cylinders. All the Al cylinders dissolved in the solution after 15 h at room temperature, and the sample is subsequently rinsed in pure water. In this way, the porous SiO2 on the Si substrate is produced. From our results, the values of all lifetime components in the spectra of Al-Si thin film are less than 1 ns, but the value of one of the lifetime components in the spectra of porous SiO2 thin film is T = 7.80 ns. With these values of lifetime, RTE (Rectangular Pore Extension) model has been used to analyze the pore size.

篇10：THAT用法总结
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：
第一、that 用作形容词（后接复数名词时用those）。
它用来指已被提到的人或物；也可表对比，指两个中较远的那个。
what about that book you borrowed from me last month？
请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
that little son of his 他那个小宝贝儿子
that george！乔治那家伙！（含有轻蔑语气）
第二、that 用作代词。
1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
that is what he told me.
what is that (which) you have got in your hand?
the price of rice is higher than that of flour.
2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）
he talked about the teachers and schools that he had visited.
i think it one of the most wonderful films that the film company has ever produced.
she has little information that is useful for our research.
is there anything that i can do for you?
请注意，that 在定语从句中作宾语时通常可省略。
the books (that) i sent you will help you in your studies.
第三、that 用作连词，引导名词性从句,状语从句和强调句。
1. that名词性从句。
①引导宾语从句。及物动词后的引导词that可省略。

that the earth goes around the sun is known to everyone.
（it is known to everyone that the earth goes around the sun.）
③引导表语从句。
the trouble is that we are short of money.
④引导同位语从句。
引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明：
the news that he resigned from office surprised us.
the idea that he holds is very common nowadays on campus.
2. that引导状语从句
①引导目的状语从句。
bring it nearer that i may see it better.
②引导结果状语从句。

as作连词，相当于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。
2.引导原因状语从句，作“因为，由于”解，与because的用法相近。eg;
I must stop writing now，as I have rather a lot of work to do.我必须停笔了，因为我还有许多工作要做。
3.引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg：

He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。
My hometown is no longer the same as it was.我的家乡再也不像过去一样了。
2.引导非限制性定语从句，用来指代它前面的整个句子(即先行句)，意思是“这一点”。这个分句可以位于句首、句中或句末。eg：
As is well known，oceans cover more than 70% of the earth.我们知道，海洋占地球面积的百分之七十以上。
篇12：that用法总结
that还常用以代替who, whom, which,但that...which中的that用做关系代词的先行词。
that可以用作连词
that用作连词时可引导主语从句、宾语从句、表语从句、同位语从句和状语从句。
that还常引导间接引语或形容词后面的.从句。
that在以it作形式主语的句子中或引导宾语从句、状语从句时常可省略。

篇16：on用法总结
（2）on表示地点、位置,有“在.旁”、“接近”、“靠近”之意.如：
a house on the main road 临大街的房子,sit on my right 坐在我的`右边
（3）on表示状态,译为“处于.情况中,从事于.”等.如：
on duty 值日,on holiday 度假
（4）on表示“在.上面”,用在表示物体的名词前.如：
on the box 在盒子上
on和over都是介词,on表示“在.上面”,指一物体与另一物体表面相接触；over表示“在.上方”,指一物体与另一物体不接触.试比较：
There is a light on the desk．桌子上有盏台灯.（light与desk接触）
There is a light over the desk．桌子上方有一盏灯.（light与desk不接触）
表示“在.上”,介词on与in必须注意习惯用法,否则会出错.不妨比较一番：
on the tree／in the tree都译为“.在树上”.前者表示树上本身所长着的叶子、花、果实等；后者表示某物或某人在树上.
on the wall／in the wall都译为“在墙上”.由于介词不同,在使用上有区别.图画、黑板、风筝等“在墙上”,是因为它们在墙的表面上,故用on the wall；门窗、钉子、洞、孔等“在墙上”,是因为它们在墙的里面,故用in the wall.

篇17：Original component of grain size ind
Original component of grain size index in core sediment from southwestern slope of the South China Sea and its paleoenvi
A new approach to the basic composition character of deep sea sediment is discussed in this paper for indicating its paleoenvironment meaning. For this purpose high precision grain size character of sediments from core NS93-5 was analysed by using the Laser Diffraction Particle Size Analyzer, combining with results of micropalaeontologic counting and trace element and calcium carbonate testing, to illustrate some main grain size indexes and their relationship with micropalaeontologic makeup and terrigenous input. It was showed that the grain sizes of deep sea sediment may reflect materials properties and their buildup framework. There are obvious relations between indexes of grain size ranges and abundances of different micropalaeontologic groups and terrigenous matters, in which grain size of <2 μm represents terrigenous composition, that of >5 μm is mainly made up of various microfossil shells, except for containing volcanic dust layers, and median diameter (MD) of grain size may be taken as proxy of paleoproductivity or paleoecological dynamic. These index and proxy were consistent with micropaleontologic records for well indicating important features of paleoceanographic ecology, showing that the micropalaeontologic growth in the southwestern slope area of the South China Sea (SCS) was negatively correlated to terrigenous input since late Pleistocene and corresponded to glacial-interglacial global climatic changes incompletely, but had a regional particularity in this sea area.

as if 的用法
一、as if 从句的作用
1. 在look, seem 等系动词后引导表语从句。如： She looks as if she were ten years younger. 她看起来好像年轻了十岁。 It seems as if our team is going to win. 看来我们队要胜了。
2. 引导方式状语从句。如： She loves the boy as if she were his mother. 她爱这男孩，就好像她是他的母亲一样。 The child talked to us as if he were a grown?up. 那孩子跟我们谈起话来，像个成年人似的。
二、as if 还可用于省略句中 如果as if 引导的从句是“主语+系动词”结构，可省略主语和系动词，这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。
如： He acts as if (he was) a fool.
他做事像个傻子。
Tom raised his hands as if (he was going) to say something.
汤姆举起手好像要说什么。
She left the room hurriedly as if (she was)angry.
她匆忙离开房间好像生气的样子。
三、as if 从句的语气及时态
1. as if 从句用陈述语气的情况。 当说话者认为句子所述的是真实的或极有可能发生或存在的事实时。如： It sounds as if it is raining. 听起来像是在下雨。 He talks as if he is drunk. 从他谈话的样子来看他是醉了。
2. as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下：
(1)如果从句表示与现在事实相反，谓语动词用一般过去时。
如： You look as if you didn’ t care.
你看上去好像并不在乎。
He talks as if he knew where she was.
他说话的样子，好像他知道她在哪里似的。
(2)从句表示与过去事实相反，谓语动词用“had+过去分词”。
如： He talks about Rome as if he had been there before.
他说起罗马来好像他以前去过罗马似的。
The girl listened as if she had been turned to stone.
那女孩倾听着，一动也不动，像已经变成了石头似的。
(3)从句表示与将来事实相反，谓语动词用“would/could/might+动词原形”。
如： He opened his mouth as if he would say something.
他张开嘴好像要说什么。
It looks as if it might snow.
看来好像要下雪了。
