Figure 2 printing plate gaskets is higher than the 0.2 ~ 0.3mm hobber pillow, blanket below the occipital hobber 0.05mm, a2, B2 Department produces a smaller convex hull, of course, less friction and sliding, wear plates, no szlama and "" taping, fault-printing plates and high, less hierarchical dot gain, clearly, the life expectancy of the machine, the electrical power consumed less.

图2印版的衬垫矮于滚枕0.2～0.3mm，橡皮布矮于滚枕0.05mm，在A2、B2处爆发的凹包较小，当然摩擦和滑动也多，印版磨损较多，无不推不净和"杠子"障碍爆发，印版的耐印率矮、网不面放大多，条理纯楚，机械的寿命放大，电机耗电也多。

When purchasing a new loupe, it is important that you choose the correct magnification and working distance in order to ensure that you work in complete ergonomic harmony with your new loupe. Assuming the correct working posture reduces eye strain, back / shoulder / neck tension, and the related stress-induced headaches.

当你想要去购买一副手术放大镜之前，你需要确认精确的放大倍率和工作距离，这点很重要，可以确保你以后非常协调的使用这个仪器，并使得你保持正确的工作姿势、减少眼睛的疲劳度、后背，肩膀和脖子的紧张感以及避免由于相关压力导致的头痛。

MAIN OUTCOME MEASURES: Number of trabecular bone closely or not closely connected by bone cement section surrounding to calculate the rate of combination; condition of surfaces of marrow cavity and bone cement in the column by amplifier.

主要观察指标：观察CT片，测出骨水泥截面周围与骨小梁结合紧密者与非结合者的个数，计算结合率。用放大器材观察骨髓腔内表面及骨水泥内柱表面情况。

Filtering considerations are the same as for normal texturing; the size of the projected textures relative to screen pixels determines minification or magnification.

纹理过滤和普通的纹理映射是一样的。投影纹理相对屏幕像素是缩小和放大倍率来决定的。

A measure of the magnification of an optical instrument ,such as a microscope or telescope.

倍率光学仪器，如显微镜或望远镜的放大倍数电路导通器是一种简单的量测仪表，它只能检查电路的通断状况。

Therelationship of the amount of catalyst and the ee% of product was seen to be negative nonlin-ear. Catalyst 3 was used in the enantioselective addition of diethylzinc to aromatic aldehydesand gave good results. The configuration of products was determined by the configuration ofthe catalysts' chiral carbon linked with hydroxy group. Using β- amino alcohols bearing only one chiral center as catalysts for the enantiose-lective addition were studied. D-N, N-dialkyl-2-amino butanol gave poor catalytic effect be-cause of their structure. The configuration of the product is the same as the catalyst. Anotherkind of β- amino alcohols - phenylglycine derivatives and valine derivatives have chiralcenter on the carbon linked with amino group. Catalyzed by-phenylglycine derivatives 6,7, 9, 10, the reactions gave satisfied results. The optical yields exceeded 80%.

在探讨了含有两个手性中心的β-氨基醇之后，选择了只有一个手性中心的β-氨基醇，一是手性中心为连羟基的手性碳原子：D-N，N-二烷基-2-氨基丁醇；二是手性中心为连氨基的手性碳原子：D-苯基甘氨酸衍生物和L-缬氨酸衍生物。D-2-氨基丁醇的催化效果不太好，这与其结构的空间位阻较小有关系，反应产物与连羟基手性碳构型一致；由苯基甘氨酸和缬氨酸出发合成五种β-氨基醇6-10，研究了不同ee％的-6作用下的二乙基锌-苯甲醛加成反应，发现该催化剂具有不对称放大效应；-7，9，lO的催化效果也比较令人满意，光学产率80％以上，所得产物构型与催化剂构型一致。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
