The forecast result of biomass and stand growth by the equations was consistent with the actual situation.

经检验，生物量和林分生长预测方程的预测结果与实际基本吻合。

All the contents of Extractable heavy metal like Pb, Cu, Zn and Cd in limestone slagged wasteland are higher than those in contrapositive soil nearby. The slag filtrate has no effect on seed germination rate of Mung beans, Broad beans and Corns but restrains their germination vigor and protraction of hypocotyls with root restraint rate exceeding 30-50%; While it has an apparent effect on germination rate and germination vigor of sensitive seeds like Beans with P=0.05. Simulate to plant the 4 different seeds in pot for a month, Test groups have a lower data in total leaf area, plant height and weight but a much higher content of protective materials like PRO and MDA in biochemical mensuration experiment compared with CK group.

石灰炉渣废弃地中Pb、Cu、Zn、Cd重金属有效态含量均高于临近对照土壤，其炉渣淋出液对绿豆、蚕豆、玉米3种植物种子发芽率无影响，但均抑制其发芽势和下胚轴伸长，根长抑制率达30%~50%以上，对敏感种子黄豆的发芽率、发芽势（4d）影响明显，摸拟盆栽一个月苗期，4种植物试验组在总叶面积、株高、生物量方面均低于对照组；生理生化测定，4种植物其体内抗逆性保护物质脯氨酸和膜过氧化产物丙二醛含量试验组均高于对照组。

Species of zooplanktons were identified in Huangjiahu Lake (31 protozoa, 39 rotatoria, 13 cladocera, 5 copepod).

随着湖泊水草生物量的增加，浮游动物的多样性指数也随之而增加。

Water temperature was the most important factor for such seasonal variations of mcirozooplankton,especially for tintinnids and copepod nauplii.

宝珠屿海区(18测站)微型浮游动物丰度和生物量的周年变动为120～3920个/L和0.61～35.2μgC/L，胡里山外海区(27测站)分别为227～4590个/L和0.95～27.99μgC/L。

In copepod, Thermocyclops taihokuensis and Mesocyclops thermocyclopoides were dominant, and their average lengths were 730μm and 680μm, respectively. Nauplii and cyclopoid copepodites also had high abundance and biomass.

桡足类优势种为台湾温剑水蚤和温中剑水蚤，平均体长介于680~730μm之间，此外，无节幼体和剑水蚤幼体在数量和生物量上也比较高。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
