"There are two types of oyster farming: suspension culture, in which oysters are grown off bottom, in floating trays, is a labor-intensive form of cultivation that requires continuous tending and cleaning of both gear and shellfish, and bottom culture, which is similar to conventional crop farming on land; it involves selecting areas of the sea floor that provide a natural food supply, necessary currents, minimum exposure to predators, and proper temperature and then ""seeding" the bottom with shellfish stock that are left to grow to market size.

中文解释=有两种典型的牡蛎养殖场︰悬浮养殖,牡蛎不接触海水底部而在悬浮的箱架中生长,属於劳动力密集型式的养殖方式,工具和贝都需要经常照顾和清洗。底部养殖,类似於传统的在土地上种植农作物,需要选择能提供营养物、必须的水流、被捕食者接触的机会最小、和适宜的温度的海底地,然后将贝类&种植&在海底,让它生长到市场所需的大小。

研究结果表明,海藻酸钙包埋悬浮振荡培养(50r/min)是龙眼悬浮细胞原生质体培养的适宜培养方式,在含有多种生长调节剂的改良MS培养基(MP6)上,再生小克隆的形成频率可高达5%;采用龙眼胚性愈伤组织体胚诱导、成熟和萌发的优化方案,原生质体再生小克隆分化子叶形胚状体的频率达100%,萌发植株的频率一般大于45%。

The first control strategy has the disadvantages such as a large amount of computations, inherent pull-out torque, difficulties in realizing the adaptive control and so forth. For the rotor flux-oriented control, changing of load or the rotor speed will result in increased or decreased torque winding currents, which will change the magnetic field distribution in the air gap. Assumption that magnetic field is approximately equal to that generated by torque windings will affect the levitation performances.

分析表明:气隙磁场定向控制中存在最大转矩限制、非线性机械特性,难以实现自适应控制等问题;对转子磁场定向控制而言,当负载或转速变化时,由于转矩控制绕组转矩电流变化将导致气隙磁场发生改变,如果仍以转子磁场近似替代气隙磁场作为悬浮依据,必然影响到悬浮控制性能。

The last one is to change a YBCO bulk into a superconducting quasi-permanent magnet, levitation force of a YBCO bulk with 40 mm in diameter is up to 218.3N at 5mm gap over a NdFeB guideway at 77K by this method.

第三方法是将YBCO块材变成准永久磁体,此种情况下,直径为40mm的圆柱状YBCO块材在77K温度下5mm悬浮间距时的悬浮力高达218.3N。

The efficiency of re-extraction using reused EDTA reached the original level of chelating extraction only for sludge B.

Fe置换螯合铜后之DTPA悬浮液可再利用於萃取A、B或C污泥中之重金属,而Fe置换螯合铜后之EDTA悬浮液则仅可再利用於萃取B污泥中之重金属,这是B污泥中重金属结合型态多为易萃出之可交换态与碳酸盐态所致。

The results indicated that the isoelectric point of Al2O3 suspension shifted to acidic side and the absolute value of Zeta potential also increased when a dispersant was added into the suspension.

研究表明:加入分散剂使Al2O3悬浮液的等电点向酸性区移动,Zeta电位绝对值增大,其中pH值为9.56对应的Zeta电位绝对值最大,悬浮液最稳定。

When purify carries the suspension colloid grain of negative electric charge in natural raw water, it is OK that its element linear grows the positive electrical charge that contains in catenary to be opposite remove electric sex to counteract the double function that reachs adsorption to bridge at the same time, and water-solubility of starch of this kind of modified is good, burnt viscosity is stable, cast impose kind agile, it is a kind of function exceedingly good organic, inorganic and compound high polymer garrulous coagulates agent.
