Thus the light saturation of Anthurium andreanum could be at considered 500 mol.L-1.m-2, s-1 , and therefore 30% overshadow net at noon of Spring and 60% at Summer in the north of china should be suitable.

认为安祖花的光饱和点在500μmol.m~(-2)。s~(-1)。以此为依据确定在我国北方春天中午可采用30％的遮荫网，夏天应采用60％的遮荫网。

To these two types of BFP, the new schemes of towing and submergence were put forward: Type A BFP, added buoyancy with detachable cone-shaped pontoons, can be towed directly, and the self-ballast mooring submergence method can be applied into its submergence process. Type B BFP can be towed with the tied pontoons, and the submergence method is davit launch.

针对两种桶形基础平台海上作业的特殊需要，提出了新的拖航与沉放方案：A型平台由可拆卸的锥形浮筒提供浮力直接拖航，并采用自身压载系泊沉放法沉放到海底；B型平台采用绑缚浮筒拖航，吊放至海底。

An acceptable alternative is to use a demountable system which allows the filters and downstream distribution system to be removed, dried and steam sterilized between sessions. Disinfection after re-assembly to kill dislodged organisms should be carried out.

一种可接受的替代方法是采用可拆卸系统，使得过滤器和下水分配系统能在每次使用之间拆卸、干燥和蒸汽灭菌，然后在重新组装之后执行消毒，杀死游移的有机物。

On the other hand, if the damage position and the damage size are used for description of the structural damage, the mathematical model is actually stated as a discrete structural optimization problem with unknown number of design variables, since the number of damages can not be given in advance.

本文采用极大极小问题构造损伤识别的优化模型，通过凝聚函数将极大极小问题转化为一个目标函数连续可微的无约束优化问题，采用基于灵敏度分析的序列线性规划方法求解。

A power ultrasonic supply ,which can realize zero phase difference frequency tracing and fixedness of output power,is presented in this paper.

本文介绍了一种具有无相差频率自动跟踪和输出功率恒定功能的功率超声电源，此电源采用集成锁相环来实现无相差自动频率跟踪，采用 PWM方式控制 BUCK电路的斩波，达到恒功率及功率可调的目的。
