  3. The measurement system is made up of optical system, comparison system, control system and cooling system in the course of the temperature measurement of high temperature blackbody, we use filter radiometer that is a new approach to measure radiation temperature. the approach was adopted by ptb, npl and vniiofo in 1997 when they made international comparisions of spectral irradiance

    在測量高溫黑體溫度的過程中，使用了新型的輻射測溫法，濾光輻射計測量方法，該方法在1997年光譜輻照度國際比對時被ptb 、 npl 、 vn ofo等國家所採用，並得到一致認可。
  4. The results show : ( 1 ) the light compensation point and light saturation point of s1 s2 and s3 were in range of 12 ~ 27 mol / m2 s and 180 ~ 360 mol / m2 s, respectively, and they changed with the irradiance. ( 2 ) both light compensation point and light saturation point of s1 were higher than those of s2 and 83, and s1 showed greater capability against high irradiance than s2 and s3. ( 3 ) the optimal temperature of the three strains were 25, 35 and 30, respectively, and they had temporal effect. ( 4 ) respiratory rate rose as the temperature rising, and at about 40, it reached the peak

    結果表明： （ 1 ） s _ 1 、 s _ 2 、 s _ 3的光補償點和光飽和點的變化范圍分別為12 27 mol m ~ 2 ? s和144 360 mol m ~ 2 ? s ，二者可隨光照環境的變化而變化，其中s _ 1的光補償點和光飽和點均高於s _ 2和s _ 3 ，且表現出強于其餘兩個藻種的抵禦強光輻射的能力； （ 2 ）三個藻種的最適溫度分別為25 ， 35 ，和30 ，具有時間效應； （ 3 ）呼吸速率隨溫度的升高而升高，最大值出現在40附近；溫度低於25 ， s _ 1的光合速率最高，呼吸速率最低，表現出很強的低溫適應性； （ 4 ）螺旋藻的光合特性可隨光照環境的變化而變化，光強增強，可使螺旋藻的最適光照范圍增大，抵禦強輻射的能力增強； （ 5 ）螺旋藻受到溫度脅迫時，其最適光照范圍變窄，對光強的敏感性增加。
  5. Plants partitioned more biomass to the underground parts at high irradiance and more biomass to leaves at low irradiance. biomass partitioned to roots and leaves of plants at intermediate irradiance went between those of plants at high and low irradiance. defoliation of plants led to an increased partitioning of biomass to leaves, but the results were different at different time

    總體來說，在高光照水平下，植株加大了對根的生物量分配，在低光照水平下增加了對葉的生物量分配，中度光照條件下植株對根和葉的分配則處于兩者之間；葉組織損失使植株加大了對葉的生物量投資，不同處理階段結果有所不同；在低光照條件下，葉損失植株對葉的生物量分配顯著高於高光照下的葉損失植株。
  6. Generally speaking, leaf nitrogen content per unit leaf area increased under high irradiance and was significantly higher than those under low irradiance

    損傷處理可使植株葉單位葉面積n含量降低，而單位葉重n含量卻比未受損植株高。
  7. The temperature stress made the cells optimal irradiance range narrow and also made their sensitivity to irradiance. study on the daily variation of photosynthesis in different weather in four seasons in a year was carried out, too. the results showed that the daily variation curves of s1, s2 and s3 were two - peak curves in high irradiance, and the higher the irradiance was, the earlier the first peak appeared. in the weather with low irradiance ( for example, in cloudy day ), the photosynthetic rate varied with the irradiance changing

    四季溫室不同天氣（晴天、多雲天氣和陰天）螺旋藻光合速率日變化測定結果顯示，在光照較強的天氣（如晴天） ， s _ 1 、 s _ 2和s _ 3的光合速率日變化曲線呈雙峰曲線，且光照越強，峰值出現越早；在光強較弱的天氣，光合速率隨光強的升降而升降。
