The feasibility of determining the pentosan in pre-extraction liquor from eucalyptus chips by using Douglas colorimetric method was discussed in this paper. The visible spectrums of xylose, glucose, mannose, galactose and kraft lignin were compared under the same color reaction conditions. The results showed that the disturbance from hexoses and lignin can be eliminated when the pentosan is identified and determined by the maximal absorption at 553nm.

摘 要：探讨了 Douglas 比色法用于测定桉木半纤维素预提取液中戊聚糖的可行性，通过对木糖、葡萄糖、甘露糖、半乳糖和木素在相同条件下显色反应后的谱图进行比较，证明利用553 nm 处的最大吸收进行测定可以排除己糖和木素的干扰。

The possibility of dyeing with Indigo so readily and easily is due to the fact that Indigo Blue absorbs hydrogen from bodies that will yield it, and becomes, as we say, reduced to a body without colour, called Indigo White, a body richer in hydrogen than Indigo Blue, and a body that is soluble.

随即可用作靛蓝染料的可能性的事实，是由于靛蓝从本体吸收氢，使自身成分还原成无色，称为靛白，是一种可溶性、含氢量比靛蓝更丰富的物质。

According to measurement, in summer the temperature in the park is 7 to 8 degrees of centigrade lower than that in surrounding areas; in winter, the temperature gains 4 to 5 degrees of centigrade and the humidity has an increase of 10% to 20%. Such a green corridor can produce 6,000 kilolitres oxygen and absorb 8,000 kilolitres carbon dioxide everyday. It play an immeasurable role in improving the environment of the heart of capital by preventing dust, reducing noise, killing bacteria.

据测算，公园夏天的温度将比周边低7至8摄氏度，冬季温度则增加4至5摄氏度，平均湿度会增加10—20%，这条绿色长廊每天可制造氧气6000公升，吸收二氧化碳8000公升，并具有防尘、减噪、杀菌诸多功能，对改善首都中心地带的生态环境起到不可估量的作用。

It is safe to water deeply during the fall, and in fact is better than a shallow watering because the plants have taproots. It is important to let the soil dry out quite a bit between waterings: it should not still be wet when you water again.

在秋季将土壤浇水浇透比浅浅的浇水更加有利于生石花的生长，因为生石花是自根系的，有利于根系对水分的吸收。

The results show that when gravity wave's propagating in the homogenous winds, the nonlinearity is stronger in the fair wind than in the contrary wind, the background winds change the propagation velocity and path, and when gravity wave's propagating in the homogenous winds, the vertical wavelength decreases, the average upgoing energy flux reduces which implies the ambient winds absorb the energy of the wave, realizes coupling of the different atmosphere layers.

结果表明，当重力波在均匀风场中传播时，非线性效应在顺风场中比在逆风场中更显著，背景风会改变重力波在水平方向的传播速度和传播路径；当重力波在剪切风场中传播时，重力波在垂直方向上平均能流随高度的增高而减少，表明背景吸收了重力波的能量，在重力波向上传播的过程中，实现了大气各层之间的耦合。

N plus P addition gave some improved leaf N and P concentration, N ~ P ratio, and nutrient resorption efficiency.

氮、磷同添使叶片氮、磷浓度、化学计量比及其再吸收效率表现出不同程度的提高。

More water and salt are needed than normally, because these are no longer being reabsorbed.

更多的水和盐，需要比一般常见的，因为这些是不再被再吸收。

Hydrocephalus results when the fluid is produced faster than it can be reabsorbed.

脑积水的结果时，流体产生速度比可以再吸收。

Under the condition [0mmol/L,raise in vermiculite] of phosphorus stress, variation in root morphology and biomass among different soybean genotypes at seedling stage were studied, the result shows: At two-leaf age, higher P-efficiency genotypes(K1 and K2) don't develop their potential advantages; at four-leaf age, some characteristics of K1 and K2, such as lateral root number, lateral root length, root absorbent area and dry weight of shoot are all less reduced than those of intermediate P-efficiency genotypes(Z1 and Z2) and of lower P-efficiency genotypes(M1 and M2), and dry weight of root and R/S of higher P-efficiency genotypes are more increased than those of the others.

在磷胁迫[0mmol/L，砂培]条件下，对不同基因型大豆苗期在根系形态、生物量等方面的差异进行了研究，结果表明：磷高效基因型在两叶期并未发挥出其基因型潜力的优势；四叶期，磷高效基因型的侧根数、侧根长、根系吸收面积、茎叶干重等性状的受抑制程度均显著低于磷中、低效基因型，而地下干重、根冠比却受到了较中、低效基因型更强的诱导作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
