For trucks, the Double Dees Half-ups tire is perfect for a variety of track surfaces, which combines the unique Double Dee lug technology, together with the sticky yellow and blue compound, allow the flexibility necessary to compete on even the most demanding surfaces for an extended period of time.

对于卡车，双迪斯半制成品的轮胎是完美的各种赛道的表面，它结合了独特的双迪耳技术，再加上粘黄色和蓝色的化合物，允许必要的灵活性，竞争，即使是最苛刻的表面在较长的时间。

Solid desiccants Solid desiccants are characterized by an internal porous structure that contains very large internal surface areas with very small radii of curvature. The equilibrium partial pressure of water vapour above such concave surfaces is much less than that above plane surfaces and so solid desiccants exhibit a very great affinity for water.

坚实干燥剂坚实干燥剂为包含非常大内部表面以非常小半径曲度的一个内部多孔结构描绘。water.vapour 平衡部份压力在这样凹面表面之上是较少比那在平面表面之上和因此坚实干燥剂陈列非常巨大亲合力为水。

Between 4-9L exposures, C2H4 has a desorption channel at 155-180K. C2H4 desorption at 130K maybe results from BrCH2CH2Br absorbs in Br atom toward surfaces, after C-Br bond scission, because C2H4 has no opportunity to touch surfaces so it desorbs at low temperature. C2H4 desorption at 210K is likely to be desorption limited that, BrCH2CH2Br docomposes to C2H4, only to desorb at higher temperature. This C2H4 desorption channel maybe comes from defect site desorption.

曝露量在4-9L之间，C2H4在155至180K的范围内也有脱附的管道。130K的C2H4脱附可能是因为BrCH2CH2Br分子以Br原子朝向表面的方式吸附，在断了C-Br键后，C2H4分子没有机会接触到表面在低温就脱附了。210K的C2H4可能是脱附所决定的，亦即BrCH2CH2Br分解后在表面形成C2H4，随后温度升高至较高温才从表面脱附，此C2H4管道也许是来自缺陷位置上的脱附。

More often, we need to design subdivision schemes for certain known surfaces. Unfortunately subdivision scheme can do little for this, even for some simple but of basic importance curves and surfaces (such as ellipsoids and hyperboloids).

仅仅修改交点处的拓扑结构不能确保每条折痕整体的C〓连续性，所以我们在修改交点处拓扑结构的同时，还修改了交点附近的细分格式，从而确保了每条折痕整体的C〓连续性。
