在焦点上的

The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.

Previous researches didn't discuss the effects of payment ways on consumers' purchase intentions. Therefore, the first issue to be discussed is what the difference of the intentions to purchase is between two payment ways. The following is to investigate the cross effects between regulatory focus、payment timing and payment ways. The experiment is 2 x 2 x 2 x 2 x 2 mix –factor experiment of design. Every subject was assigned one of the two regulatory focus manipulations and had to judge four payment methods which were composed of two within-subject variables — payment timing and payment ways. At the same time, different product durability and product types were considered.

而以往的研究并没有针对付费方式做探讨，因此对於在「分期付款」与「一次付清」下的消费者购买意愿差异所知甚少，故本研究第一个要探讨的问题就是这两种付费方式下的消费者购买意愿是否有差别；再来由於以前关於调节焦点与付费时间对於购买意愿的影响的研究大多只集中特定产品种类上，并无全面性的探讨，因此本研究针对这部分做更深入全面性的研究；最后探讨付费方式、调节焦点与付费时间三个变数的交叉效果对於消费者购买意愿之影响。

Fixed: Some AI commands on dedicated server might be delayed when the server window had focus.

修正：修正了在专用服务器上一些AI指挥官在服务器窗口成为焦点时会产生延迟的问题。

Secondly, the research focus may be on the individual's response to the stress; in this sense stress acts as the independent variable. In the first case it is more likely to be a dependent variable, elements of the teaching and the working situation being the independent variables.

第二，这个研究的焦点可能在个人对压力的回应上，在这种意义上，压力是作为一个自变量，在第一种情况下，则更倾向于一个因变量，而教学元素和工作情况则是自变量。

Thus, Chinese is a kind of languages structuring the information focus to some extent from a typological view.

汉语的语序要适应焦点结构要求——信息焦点成分一般不能出现在动词之前，只允许其出现在动词之后，因此，汉语在某种程度上是将信息焦点结构化的语言。

Notice that a small amount of foreground focus can be gained by focusing the lens at a shorter distance than infinity known as Hyperfocal Focusing.

大多数定焦镜头在镜筒上都有超焦点刻表帮助调整最大的焦点。这就是为什么我们仍然不用变焦镜头而用定焦镜头的原因

Four aspects of research achievements include:(1)several imaging correction methods and strained estimation methods for biological tissues elasticity imaging were investigated as well as elasticity reconstruction and phantom, in vitro and in vivo elasticity imaging experiments;(2)in the fields of biological microsystem and perfusion evaluation for microvascular system, three kinds of microbubbles whose shell are albumin, sugar ester and surfactant respectively were designed and produced, then the methods to estimate the thickness of their shells were presented, moreover, the interacting mechanism of ultrasound contrast agents and tissues, as well as protein drug delivery under the condition of ultrasound sonification were studied in the molecular level;(3) At the aspect of high intensity focused ultrasound therapy system, we designed and constructed the 256-element HIFU transducers using 1-3 composite materials. And furthermore we developed the integrated HIFU system with 256-element HIFU transducers. And we made preliminary and important progresses in the research of HIFU bioeffect, lesion estimation, techniques of monitoring and imaging and characterizing of structure of HIFU transducer;(4)The real-time method of voice source regeneration based on compensative regulation of physiological parameters was investigated in the field of medical rehabilitation. We addressed the physiology and biophysics of vocalization, modeled voice source regeneration based on compensative regulation mechanism, and put forward an integrated evaluation about the speech rehabilitation and the regenerated voice source; Sixty-one archived journal papers were published, as well as ten in international journals, and eighteen publications were embodied by SCI.
