To ensure easy assembly, the seat and back of the Adirondack chair are pre-assembled and detailed instructions are included.

为了确保易于组装，座位和靠背座椅的阿迪朗达克预先组装和详细说明，均包括在内。

Adaptive subdivision is performed only in the areas facing to the viewpoint in the pre-process. And in the each adaptive subdivision, we choose the normal angle of the adjacent faces as the control error to detect whether the approximation is sufficient. Sharp edges are automatically tagged according to the given thresholdθand subdivision masks are designed based on different sharp degrees.

在预处理过程中，只选取面向视点的网格作为能够被进一步自适应细分的网格；在自适应细分过程中，用相邻面片的法向夹角作为控制误差来反映细分的逼近程度是否足够；并根据预设的阈值θ自动标记网格中的尖锐特征边，重新设计尖锐特征处的权值掩模。

In addition, Beers won pre-publication interest from Adolph Meyer, one of the most prominent psychiatrists of the era.

另外，在自传出版之前比尔斯赢得了Adolph Meyer 的注意，那个时代最重要的精神病学家之一。

Methods60 SD rats were divided into 6 groups at random by SAS, the rats were pre treated with drug or 0.3％CMC by lavage respectively according to the regulation, soaked after injection s.c with 0.08mg/100g adrenine into ice water for 5min to prepare rat model of acute blood stasis.

方法用SAS统计软件把60只大鼠随机分为6组，消栓降脂丸预防给药14 d，皮下注射肾上腺素，冰水浸泡建造急性血淤模型，采血测定血液流变学和血小板聚集指标。

The Pre-destined Match , closely assimilating Olympic medals to Liangzhu Culture which best represents the Jade culture, provides wider perspective to advertize the medals while making it more valuable to make Chinese culture widely known.

"金玉良缘"将奥运奖牌与玉文化最重要代表之一的良渚文化联系起来，为奥运奖牌的宣传创造了更为广阔的空间，同时也提升了奥运奖牌传递中华文化的功能。

32P isotope tracing technique was used in this study,and the results indicated that phosphorus stored or pre-existed in roots would be remobilized in maize under phosphorus deficiency from root cortical cells with lysis to shoot mostly rather than root apex during aerenchyma formation.

Kraus等的试验表明玉米根系从土壤中吸收的32P可在根皮层内保留15 d，之后逐渐减少[2]。这意味着与叶片的情形相似，根内也进行着磷的活化和再运转。当植物处于磷胁迫下时，根系吸收的磷素远不能满足植物各器官生长发
