In another test device with visible male bird stimulus, females chose the male with the 3-alkanol blend of males over the other male with female preen gland secretion, whereas did not differentiate their responses between the males with either this blend or male preen gland secretions.

正如论文评阅人所说：尽管很久以来就推测有些鸟的尾脂腺可能产生性信息素，但是该论文第一次提供了这类信息素组成的实验证据，也为以后的同类研究提供了参考方法。

This new model eye can simulate the different state of refractive error, and offer the assistance for the teachers to demonstrate retinoscopy to students, which is an effective approach to solve the problem to observe the diverse movement of reflective light from model eye.

这种新型检影模拟眼不但能够模拟各种人眼屈光不正，而且该装置可以提供示教功能，能够提高检影验光学习的效率，使眼视光学检影验光教育培训带来了全新的方法成为可能，为解决检影模拟眼影动观察的示教提供了有效办法。

The revolution in digital technology has increased the ease of manipulation, reproduction, retransmission, and distribution of digital information.

数字化技术的革命在为数字信息的处理、复制、转发以及销售提供便利的同时，它也为非法复制和非法篡改提供了可能。

This paper studies optimal helicopter flight operations in the event one-engine failure. A three-dimensional point mass with a yawing motion of UH-60A has been used to study RTO and CTO from an elevated heliport or from a heliport, A first order dynamic of the OEI contingency power is considered. Flight after engine failure are formulated as nonlinear optimal control problems.

双发及多发直升机单发失效后，直升机飞行所需要的功率由剩余发动机提供，而在某些需要大功率的飞行状态时，如起飞状态、着陆状态等，剩余发动机提供的功率可能满足不了，这就需要对剩余发动机的可用功率进行合理利用。

As guiding organizational structure in post modernity society network typifies unfolding, dispersivity and schematization. It provides necessary premise and basic condition for urban and rural fair communication and offers chance and possibility for cultural integration.

网络作为后现代社会的主导组织结构有着开放性、分散性、系统性特征，为城乡间的平等交流提供了必要前提和基础条件，同时也为文化整合提供了机会和可能。

Traction: Indoor(8), outdoorwell !! the shoe does provide pretty good traction on a semi dust indoor floor. The small wave like pattern ( also the ten sign but i doubt that it provide any traction), it does give me the traction that i need to cut into the paint, but sometimes it is really hard to have a pull up jump when you are running at a fast speed. It will make you slip a little , and that will probably delay your jumping and the height that you jump will be reduced!!

嗯，即使是在蛮脏的室内木头地板上，这一双鞋仍然很实在的提供了相当好的抓地力，鞋底的小小波浪纹设计(还有十字纹路的设计不过我对它们所能提供的抓地力感到怀疑)，很实在的给予了我切入禁区时所需要的抓地力，但是当您高速奔跑时有些时候非常难全力跳起来，这种设计会让您感觉有些滑滑的，而且它可能会让您跳的更慢一些甚至是跳的没有以前高。

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。

It is essential to engross the firm's assents to offer sponsion, mortagage and fund, which will lead to change the manage achievement of firms since it has the non-constructive effect and positive relation to earnings management.

向关联方提供担保和抵押与提供资金，实质是占用了公司资产，对盈余管理起非建设性的效应，与盈余管理正相关，可能会导致企业的经营业绩的变化。

XML is a simplified version of SGML (Standard Generalized Markup Language). As a simple and flexible standard format, it provides an effective means for Web-based application. Meanwhile, Adobe Flex 2 is a rich Internet application framework based on Adobe Flash that enables you to productively create beautiful scalable applications.

XML是一个精简的SGML，作为一个简单而灵活的标准格式，为基于Web的应用提供了一个描述数据和交换数据的有效手段；而随着Web2.0的升温及RIA的广泛应用与发展，Adobe公司推出的Flex为开发人员构建下一代丰富互联网应用提供了无限的可能。

Weak and global supervenience were determined to be too weak to provide a dependency link.

就提供依赖性而言，弱的和普遍性的附生性太弱了，而强附生性作为唯一一种可能的选择，也并不能提供一种依赖关系，而只是一种持续的关联关系。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
