Within day in the hereafter, eight hundred half's business has increased by one times than front the stage manner is full.

在以后的日子里，八百半的生意比台风前整整增加了一倍。

The analysis shows that vertical growth is achieved thanks to discrete contact points and regions with continuous contact, that the contact pressure creates tension in the stem as observed experimentally, and that there is a maximal radius of the pole around which a twiner can climb.

这个模型可以解释为什么藤蔓不能在半径大于一定值的树干上生长，他们计算出当树干半径大于3.3倍的藤蔓自然曲率半径时，藤的尖端便不能继续缠绕树干向上生长，而是自身卷曲起来。文章的后一页半研究了摩擦力的影响，很明显，摩擦力是使藤蔓植物能够支撑自身重量的主要原因。

Fast propagation of Balsamine was studied and the results were listed as below.

芫菁为鞘翅目芫菁科昆虫，其成虫和幼虫体内均含有一种倍半萜烯毒素——芫菁素 [1] ，因芫菁素不仅可以医治多种癌症，还可升高人体白血球，而成为一种重要的药用昆虫。

A fully ethoxy-terminated polymethylsilsesquioxane has been prepared via a dehydration ethanolysis reaction between absolute ethanol and an ordered ladder-like HO-Me-T, which improved long-term storage stability of HO-Me-T. Meanwhile, EtO-Me-T can still participate in the cross-linking reaction with hydroxy-terminated PDMS in the presence of catalyst.

利用含端羟基的LPS与无水乙醇之间的催化脱水反应合成了一种乙氧基为末端基团的活性梯形聚甲基倍半硅氧烷，有效地改善该类聚合物的长期稳定性；同时，该乙氧基封端聚合物仍然具有活性，可以代替常用的正硅酸乙酯与羟基硅油进行交联反应。
