Cars that were usually gleaming stood dusty in their drives and lawns that were once emerald green lay parched and yellowing -for the use of hosepipes had been banned due to drought.

车道上，平日里锃亮光洁的汽车现在却落满了灰尘，本来碧绿如玉的草坪也变得焦黄枯干--由于缺水，水管里的水被禁止用来浇灌。

In order to accomplish this change, our research have made several important break-through by revising new formulation especially in (1) catalyst mix,(2) adjustment of water content,(3) addition of chain extenders and crosslinkers, and(4) utilization of long-chained polyols. By doing so, the general performances of our new non-yellowing foam products are comparable to those of the traditional TDI based products. In certain mechanical properties in areas such as tensile strength, split tear strength, and elongation our measured values of 1.89 kg/cm2, 1.47 kg/cm, and 355 % respectively have out-performed the old materials.

能在研究中突破的原因，是因针对聚胺酯发泡体配方中的催化剂、水含量、链长剂种类、交联剂及搭配商业之改质长链三元醇，做各式各样之配方调整而成，与传统商业用之芳香族发泡体相比较，基本的成泡指数及性质相比拟上已相近，在抗张(1.89 kg/cm2，比TDI系统增加2.2倍)、撕裂(1.47 kg/cm，比TDI系统增加1.7倍)、延伸率(355 %，比TDI系统增加1.6倍)等机械性质上甚至比芳香族发泡体有更佳的表现。

Leaves start yellowing and roots/stolons darken, and easily pull up.

叶片开始发黄，根/匍匐茎变黑，松动。

It was found that the main reason why SBS containing oil was easy to yellow was that there is plenty of polycyclic aromatic hydrocarbon in the extender oil,PAH can easily turned quinones with yellow.Antiyellowing performance of SBS can be only developed in a little extent when antioxidants were added.The anti-yellowing performanc...

研究结果表明，充油SBS产品变黄的主要原因是油品中的稠环芳烃在光氧环境中易转化为黄色的醌，添加抗氧剂对延缓产品变黄的作用不大，通过催化加氢消除填充油中的芳烃或添加适当的光稳定剂可以提高产品的耐黄变性能。

The metabolism of protein and nitrate nitrogen in tobacco leaf during curing was studied by using the electric-heated flue-curing barn designed and made by Henan Agricultural University in which the temperature and moisture were controlled automatically.The results indicated that the content of protein decreased gradually while the content of amino acid increased with the proceeding of curing.And either of them had a rapid-changing stage in the middle of yellowing period and color-fixing period.The activity of proteinase reached the peak respectively after curing 24 hours and 60 hours.

对烘烤过程中烤烟烟叶蛋白质与硝酸盐代谢规律的研究表明，蛋白质含量随烘烤进程发展逐渐减少，氨基酸含量逐渐增加，且均在变黄中期和定色期有一个快速变化阶段；烤后烟叶中氨基酸和可溶性蛋白的含量与鲜叶中可溶性蛋白的含量呈高度正相关；蛋白酶活性在烘烤开始后24h有一个高峰。

I agree with him, however, that the two-volume Business Cycles of 1939 was a massive failure, in both senses of the phrase. I still have the yellowing copy that I bought as a student.
