Although the liquidation of nearly three billion dollars of brokers' loans contracted credit , and the Reserve Banks lowered the rediscount rate, and the way in which the larger banks and corporations of the country had survived the emergency without a single failure of large proportions offered real encouragement , nevertheless the poisons were there : over production of capital ; over ambitious expansion of business concerns; overproduction of commodities under the stimulus of installment buying and buying with stock-market profits; the maintenance of an artificial price level for many commodities; the depressed condition of European trade .

译文尽管清算了经纪人三十亿美元借贷增加了信用、国家储备银行拿出钱补贴降低了贴现率、大银行和大企业没有蒙受什么损失就渡过难关也使人振奋，但毒素仍然存在：投资过热、盲目上马、分期付款购物和凭股市收益购物造成商品生产过剩、人为调节价格以及对欧贸易不景气。投资过热、盲目上马。（运用我们现在的习惯用语）对欧（对字不能少，不是欧洲贸易）凭股市收益（凭字不能改为用字，文章本意是还未兑现，估计后市可能仍为多头市场，于是提前消费

The thermal property studies indicate that the mass loss of compound B was 54.39% at 242.2~750℃, and when the temperature was 1000℃, there was 25.11% char residue left, which showed that the title compound has a good thermal stability and char forming capability. Using acetonitrile as the solvent instead of trichloromethane or 1, 2-dichloethane gave higher yield. During the synthesis, the yield was very low when triethylamine was used as acid acceptor alone, and when a little amount of 4-dimethylaminopyridine was added at the same time, the yield could be 81%.

结果表明，所合成的化合物B的结构与预期的结构一致；热性能研究表明，化合物B在242.2~750℃质量损失为54.39%，1000℃时仍有25.11%的炭残渣，显示出优异的热稳定性和成炭性；在相同反应条件下，用乙腈作为溶剂的反应产率比使用氯仿和二氯乙烷为溶剂的高，并且在合成过程中，单独使用三乙胺作为缚酸剂时产率很低，而当同时加入少量4-二甲氨基吡啶时，产率可达81%。

In order to decrease copolymerization loss of isoprene during thermal dimerization of cyclopentadiene in C5-fraction,the effect of three inhibitors,diethylhydroxylamine,p-tert-butylcatechol and o-nitrophenol,on dienes' polymerization in the process was investigated by experiment with sealed glasstube.

Figure 9 shows the configuration of the experimental equipment employed in this research. The thermal input is provided primarily by a DC power supply. In addition, a 600W thermostatic tank at the heat exchange section is used to control the water temperature, and it works with a flow regulator to remove heat through the water jacket. Thermocouples are separately embedded at the inlet and outlet of the water jacket to monitor the temperature change. In the course of the experiment, each of the heat spreaders is enclosed by heat-insulating materials to prevent heat loss. The following are the main experimental parameters
