In addition, if you want to set up a 2.35 format screen without an anamorphic lens, you can do that on both projectors by using the powered zoom lens adjustments to zoom back and forth when you change from 2.35 to 16:9 material.

此外，如果你想建立一个没有变形镜头一2.35格式的屏幕，你可以做两投影机使用电动变焦缩放调整镜头来回当您从2.35更改为16：9材料。

This eliminates the need to buy an anamorphic lens, but it introduces the nuisance factor of having to manually adjust the zoom lens and vertical picture height as well every time you change the format of the viewing material.

这消除了需要购买的变形镜头，但它引入了滋扰的因素，而不必手动调整变焦镜头和垂直图片高度以及每次改变格式的浏览材料。

The 1.5x zoom lens has enough range to move back and forth from 2.35 to 16:9 if the user wishes to set up a 2.35 CIH system with zoom changes rather than the anamorphic lens.

的1.5倍变焦镜头，有足够的范围，摆脱2.35来回16时09分，如果用户希望建立一个2.35 CIH病毒系统变焦的变化，而不是变形镜头。

If you have the extra $500 to spend on higher performance, stepping up to the HC3800 will reward you with a superior image as well as a variety of other features--a Diamond series glass lens with 1.5x zoom range, a 5000-hour lamp life in eco mode, anamorphic lens modes, and a two-year warranty with a one-year or 500-hour warranty on the lamp to name a few.

如果你有多余的500美元，升级到HC3800将会赋予你更号的图像以及很多其它功能－－Diamond系列的1.5倍变焦玻璃镜头，经济模式下5000小时的灯泡寿命，变形镜头模式，以及两年整机质保、一年或500小时的灯泡质保。

Luses for the Panasonic include a much better working Frame Interpolation scheme, the motorized zoom and focus, plus lens memory, which allows the PT-AE3000 to essentially emulate having an anamorphic lens, so that you can use a 2.35:1 screen, and watch Cinemascope movies without the letterboxing at top and bottom of the screen.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
