一种利用孤雌生殖进行裙带菜种苗培育的方法
2)将上述孤雌生殖成熟的孢子体的孢子叶置于海水中释放得到游孢子
3)上述附着游孢子的苗帘在光强50?80μmol?photons?m?2s?1
4)将雄配子体与附着在苗帘上的雌配子在50?80μmol?photonsm?2s?1光强下完成发育和受精过程
待幼孢子体达到200?500μm左右
其特征在于:1)将雌性配子体进行诱导培养至幼孢子体达到1mm以上转入充气培养条件下
待释放得到游孢子的海水颜色为黄褐色后
水温18-22℃
转到海上栽培
完成孤雌生殖孢子体的生活史
将游孢子附着在苗帘上
光周期12h白天:12h黑夜条件下培养13?15d
即实现裙带菜的培育。
形成孤雌生殖成熟的孢子体
而后将苗帘放入新鲜海水中
待萌发的游孢子全部发育成雌配子体并充分生长后
降低光强至2?10μmol?photons?m?2s?1
延缓配子体的发育使其度过高水温的夏季

Using a spherical mirror of 400mm diameter and 12mm thickness
active supporting technology of thin mirror is researched. The axial support of the mirror is composed of 12 active supports and 3 fixed supports. The force actuator
which is composed of displacement actuator and force sensor
is installed in the active support. The mirror surface is tested by Zygo interferometer. For calibration
each actuator exerts unit force alone
and the surface variation is tested and taken as the response function of the actuator. The response functions of all actuators compose the stiffness matrix. Then the stiffness matrix is used by damped least square method to determine the correction force of each active support. In order to analyze the correction capability of the active supports
14 Zernike modes of the mirror surface are generated and tested respectively
and 7 modes are selected for correction. Initially
the RMS error of mirror surface is 1.16 I( =0.6328nm)when all actuators exert the same force. After 5 iterations
the RMS error of mirror surface is reduced to 0.13
close to the original surface quality. 2010 Copyright SPIE - The International Society for Optical Engineering.

The replacement of CH4 from its hydrate in quartz sand with 90:10, 70:30, and 50:50 (W-CO2:W-H2O) carbon dioxide-in-water (C/W) emulsions and liquid CO2 has been performed in a cell with size of empty set 36 x 200 mm. The above emulsions were formed in a new emulsifier, in which the temperature and pressure were 285.2 K and 30 MPa, respectively, and the emulsions were stable for 7-12 h. The results of replacing showed that 13.1-27.1%, 14.1-25.5%, and 14.6-24.3% of CH4 had been displaced from its hydrate with the above emulsions after 24-96 It of replacement, corresponding to about 1.5 times the CH4 replaced with high-pressure liquid CO2. The results also showed that the replacement rate of CH4 with the above emulsions and liquid CO2 decreased from 0.543, 0.587, 0.608, and 0.348 1/h to 0.083, 0.077, 0.069, and 0.063 1/h with the replacement time increased from 24 to 96 h. It has been indicated by this study that the use of CO2 emulsions is advantageous compared to the use of liquid CO2 in replacing CH4 from its hydrate.

The design method and result are described for an infrared afocal zoom system. Its zoom ratio is 4
(2) Functions such as changing the field-of-view
and the corresponding field of view is 3-12. The working waveband is from 7.5m to 10.5m
focusing for objects at finite distances and athermalizing the system can be achieved by axially moving a single element in the system.
and its total length is required to be no more than 350mm. The final optical system consists of 7 elements
with aspheric surfaces and a diffractive optical element. It achieves diffraction-limited imaging at the far infrared waveband. Two conclusions can be drawn from the design. (1) Using diffractive optical elements in the design of an infrared optical system is an effective approach to control color aberrations
which eliminates the need to use exotic and expensive materials and helps to reduce the cost of the system
