7、 nanosphere, nanorod, helix, capsule and nanotube. we will focus on the preparation and catalytic application of mesoporous silica with nanotube morphology. p11 the sem images of samples: a1, a2, a3 are shown in the figure. it can be seen that sample a1 is nanowire-like with length of about 2m and d

23、de. p20 thanks篇二:来自公司人员们的ppt制作演讲经验 由于近来半年我在公司做ppt演讲也有近十次了,所以今天我也想谈一谈这个问题,补充一点我的看法。如何做好ppt演讲。 首先我们要先明白ppt在演讲中的作用。在演讲中ppt的重要作用同样是传递信息,不过它有其特殊性。ppt可以是演讲内容的一个简单的精明的框架。为演讲者减轻负担,也为听众提供了更简单的抓住演讲主要内容的方式。ppt在演讲中应该始终扮演着助手的角色,他的作用应该是辅助于演讲者的表达。如果我们把顺序反过来,事情就变了味道。但看起来却说的过去,比如我们的演讲是为我们的ppt添砖加瓦,用以说明它的“美丽”。这种观点也就是p
24、pt成了主角,我们要尽力把它描述清楚。但事实上我们是为了演讲而做的ppt,而不是为了ppt做演讲。前两天飞利浦公司来人到我们公司做了一场关于lcd的演讲。主讲者是个欧洲人。他一身标准的商务着装,虽然有啤酒肚,但标准的着装也使他在我们这群身着休闲装来工作的年轻人面前显得很有权威。他的演讲让我眼前一亮。他并没有按照标准的ppt从上到下按顺序演讲,而是让ppt跟随他的思想而动。没有固定的顺序,ppt总在上下翻动。 我所见过的几种糟糕的ppt演讲 1. 糟糕的文字。 这是一个女同事的ppt演讲。她有女人普遍具备的性格:认真,仔细。但她有些缺少自信。当上司让她准备一个演讲,并表示这关心到她的评价的时候,
25、她做了这样的一份ppt。从ppt第一页的目录后,每一页都密密麻麻写满了她找来的有关资料,直到最后一页结束。她害怕漏掉一点点自己辛勤的劳作。整个演讲成了她的阅读课,她把ppt从头念到了尾。出于尊重我没有退席,这也让我第一次意识到尊重一个人也要如此的痛苦。演讲结束我连她讲的题目都不记得了。 2. 糟糕的花样。 ppt软件的强大,也可以体现在它内容是“活”的。你可以设计出各种内容进入推出的方式,甚至你可以让一个字像地板上的乒乓球一样跳个不停。我曾经见过一个同事的ppt,那个ppt结合了各种特效,仿佛我在看一部好莱坞大片,但又不一样。我总在想,那种样式他是怎么做出来的,或者,原来ppt还可以干这个。最
26、后同样我不记得他讲过什么,只记得ppt是如此的强大。 3. 糟糕的形象。 有关形象的问题我以前说过一些。英格丽张在她的书中举过很多例子,为什么很多有才华的人失去他们本应该从vc那里得到的投资,只因为他们糟糕的形象。蓬乱的头发,落满灰尘没有光泽的皮鞋.人们普遍不相信形象糟糕的人,又怎么会把钱给这样的人。我总在告诫自己不能以貌取人,但有时候这些事情源于自然。我有的同事头发没梳就来上班,甚至去做ppt 的报告。有的人在做演讲的时候精神疲惫,说话有气无力。他们的形象一上来就在告诉我,他是一个不注重细节的人,他是一个身心疲惫的人,他是一个没有激情的人.同时我们也会把这些感情色彩无情的凌驾到他的演讲上。那
27、时他将很难翻身。这些多么无情,但很真实。另一种糟糕的形象发生在以下这样的情况。有的演讲在结束后你根本不知道演讲者的相貌,因为整个演讲过程中他总是用臀部对着观众,演讲结束后人们只认识到了他“伟大”的背影。 如何做一个好的ppt演讲 一个好的ppt演讲不是源于自然,有感而发。在我看来一个好的ppt演讲需要演讲者的精心策划与细致的准备,同样必须对ppt演讲的技巧有所了解。 我们辛辛苦苦准备的內容只占7;简报成功最主要的关键是能度/形象,占了58;其次是声音,占35。回想一下所谓的名嘴,那么这层道理也就不说自明了。 ppt制作技巧 1. 内容:演讲的骨架 多使用图形 少用术语ppt的内容应简洁而突出重
28、点,在10/20/30法则中强调使用30号字体。 我更同意如下建议: 大标题 44 点 粗体 标题一 32点 粗体 标题二 28点 粗体 标题三 24点 粗体 如果有必要请多以图形表达你的思想。因为图形更容易让人理解,同时也让听众印象深刻。当然图形也会帮助演讲者更好的进行阐述。但是同样你必须注意图形上标注字体的大小。 如果你的演讲内容比较专业,请考虑你的听众,避免使用你的听众群不理解的术 语。如果非要使用,请一定要解释清楚。还是上面提到的那次飞利浦来我公司的演讲,lcd本身包括了很多术语,加之语言不通,让我们很多人听得贩晕。讲师是好的,但没有考虑语言和术语这些东西,听众听不下去,演讲者也就白忙
29、活了。 2. 花样:正式场合不使用任何ppt动作非要使用最多不超过三种如果在非常正式的场合下进行ppt演讲,在ppt制作中我建议不使用任何“花样”,包括自定义动作,幻灯片切换样式等。一个朴素的,中规中矩的 ppt是不会引起非议的。这时你可能得不到别人对你ppt的夸奖,但决不会有人说你做的不好。当然如果在非正式场合你可以加上一些效果。但我建议最多不要超过三种。这样你的ppt还是简洁的,不至于落入“杂”的境地。 3. 形象:穿着正装 目光接触 保持微笑 请穿着正装进行ppt演讲,首先给听众一种权威的形象。我没见过余世维穿着牛仔裤去做演讲的,也没有见过那家公司过来演讲是穿着体恤的。你不要和我说比尔盖
30、茨,他可以这么做,如果你是比尔盖茨我也不介意你这么做。正确着装的同时,请你在演讲之前保持精神焕发的状态,你要有一种积极向上的态度,并相信这种态度同样的可以影响你的听众。在演讲过程中请始终保持与听众的目光接触,你可以在他们眼中读出自己下一步要做些什么,也可以让听众知道你关心他们。 最后讲一下制作ppt的两个原则 1. magic seven原则。每张幻灯片传达5个概念效果最好。 7个概念人脑恰恰好可以处理。 超过9个概念负担太重了,请重新组织。 2. kiss (keep it simple and stupid)原则。因为我们做ppt针对的是大众,不是小众。我们的目的是把自己的理解灌输给听众。
31、深入浅出才代表你对知识的真正掌握。 制作一个好的ppt并不简单,做一个好的演讲更难。掌握一点这里面的技巧是必须的。 cherie kerr 了解 powerpoint 在商务会议中振奋人心并具有说服力的原因所在。她也清楚地知道可能产生负面作用。 决窍:在powerpoint 中,通过选定您要改变的图形,可迅速将自选图形转换为另一个自选图形而不会改变格式,单击绘图按钮,指向“改变自选图形”,然后单击新的自选图形。 “她将成为您最好的朋友,” 在加利福尼亚担任公共关系顾问的 santa ana 说。 “前提是您必须正确使用。” kerr 对于这款广受欢迎的 微软演示和图形程序一分为二的看法也正反映
32、出了企业界和学术界长久以来对此问题的争论。很多人将 powerpoint 推崇为有价值的强大商业工具,但是也有一部分人认为它是实现有效互动的障碍,会搅乱、歪曲甚至毁掉沟通。 然而,正如 kerr 指出的那样,任何关于 powerpoint 优劣的讨论只是说明了利用此程序胜人一筹的重要性。 这里有 10 种使用 powerpoint 的方法,能够让您的业务更加出色。 采用强有力的材料支持您的演示。 在某种程度上,powerpoint 的易用性可以成为它最致命的弱点。 虽然利用它可以轻松创建引人注目的幻灯片和图形,但您需要知道 powerpoint 并非独立存在。 观众前来并不只是为了观看屏幕上显
33、示的影像,更多的是为了聆听您的演说。 您需要构建一组强有力的 powerpoint 程序,但也应确保您的口头评论同样引人入胜。 “powerpoint 不负责演示,只负责制作幻灯片,”弗吉尼亚中洛锡安 audience first总裁 matt thornhill 说。 “切记您创建幻灯片的目的是支持口头演示。” 简单化。 我们可能都曾见过演讲者在 powerpoint 和其他演示中似乎准备充分胸有成竹的情形。 毕竟,他引以为傲的明显只是各个功能、特殊效果以及其他可用的小技巧。 其实最有效的 powerpoint 很简单,只需要易于理解的图表和反映演讲内容的图形。 权威人士建议每行不超过五个字,每张幻灯片不超过 5 行。 “不要用太多的文字和图形破坏演示,”kerr 说。 “您真的需要在屏幕上显示出一切吗?”
