The studies on analysis of the product shew GC analysis had better stability and recurrence.Column temperature was set 100℃ for 1 min and was programmed at 16℃/min to 260℃,then 10℃/min to 330℃,last at 5℃/min to 370℃. Results of study on different catalyzers shew phosphotungstic acid was the best catalyzer.

产物的分析测试研究表明：GC分析比RP-HPLC法的稳定性和重复性好，适宜的操作条件为：柱温在100℃下维持1分钟，先以16℃/min升到260℃，然后以10℃/min升到330℃，再以5℃/min升到370℃。

When pea ( Pisum sativum L.,Alaska strain) was grown in short\|day conditions,the apical bud senescence started with the transformation of the bud from vegetative to reproductive growth.DNA fragmentation was detected during the senescence using the terminal deoxynucleotidyl transferase\|mediated dUTP nick end in situ labeling method.The cell ultrastructural changes were similar to apoptosis in animal cells:the apical meristemetic cells underwent the programmed cell death.This wa...

显微、超微结构研究表明，短日照条件下豌豆顶芽的衰老过程是从营养生长锥向花芽的转化，而用DNA原位末端标记、Caspase 8WesternBlot和 14 0bpDNA片断积累的试验结果证明，转化为花芽的整个生长锥细胞发生了编程性死亡，而且其最顶端部分细胞首先发生PCD ，而顶端周围的分生组织细胞逐渐分化出花芽的各部分，但顶芽最后并没有发育成为完整的花，所有细胞就都发生PCD ，从而顶芽衰老

"The increased levels of apoptosis in the midbrain and pronephric kidney we observe suggest that atrazine may cause tissue malformation by inducing ectopic programmed cell death, either directly or indirectly through a mechanism that has not been identified," wrote the researchers.

&提高水平的细胞凋亡的脑和肾pronephric我们观察表明，莠去津可能会导致畸形组织异位诱导细胞程序化死亡，直接或间接地通过一种机制，还没有确定，&研究人员写道。

During temperature-programmed combustion, the evolution sequence of different sulfur forms is aliphatic sulfur, aromatic sulfur and pyritic sulfur, thiophenic sulfur and sulfatic sulfur.

2大同煤各形态硫燃烧逸出的基本顺序为：脂肪硫，芳香硫和黄铁矿硫，噻吩硫和硫酸盐硫。

When cells undergo programmed cell death, cell corpses adopt a refractile and disc like structure. Using this morphological change as a cell death marker, we analyzed the death of the first 13 cells in the AB cell lineage of wild type and cnx-1; crt-1 mutant embryos.

进一步以4D摄影分析线虫AB世系细胞中最早死亡的13颗细胞之相对死亡时间和细胞尸体持续的时间长短的结果则显示，此死亡细胞数量提高的现象应是源於吞噬步骤发生问题而非细胞死亡执行上的问题。

On the 12〓 day, classical DNA ladder appeared after electrophoresis. Fine structural observation showed that the senescence process in this system is a highly ordered programmed cell death process, and its function was speculated as nutrition remobilization. All these suggested that this system is a plant cell apoptotic system.

从第8天开始有些细胞核开始出现TUNEL阳性反应，在处理12天时，总DNA电泳中出现了典型的DNA ladder，超微结构观察发现其衰老过程是一个高度有序的程序化死亡过程，推测功能上是一个营养物质再利用的过程，因而这一体系是一个细胞凋亡体系。

NO+NH3 temperature-programmed reaction runs over reduced catalyst samples pretreated with various oxidizing species showed that both NO2 and HNO3 were able to reoxidize the V catalyst at much lower temperature than gaseous O2: furthermore, they significantly enhanced the NO + NH3 reactivity below 250 C via the buildup of adsorbed nitrates, which act as a surface pool of oxidizing agents but are decomposed above that temperature.

不+NH3 温度-规划反应奔跑结束减少催化剂样品预先处理与各种不同的氧种表示两者的没有 2 和 HNO3 能够到再氧化 V 催化剂在非常低的温度超过气体的 O2：此外，他们重要地可提高的那不+ NH3 反应度在下面 250？C 经由组织吸附硝酸盐，哪一个行为当做一表面池氧代理人但是被分解上方哪一温度。

The improved threshold retracking algorithm is optimized in the paper. Several waveform retracking algorithms are analyzed. Then a waveform retracking system is programmed. Several retracking methods are used to retrack the EnviSat waveform over the Mediterranean Sea. The improved threshold retracking algorithm is the most robust retracking method and more suitable for the EnviSat waveform retracking over the coastal Mediterranean.

分析了EnviSat雷达测高波形重定算法，并对Threshold算法进行了优化，开发了波形重定程序；以地中海为实验区，利用几种波形重定方法，对近岸海域的EnviSat测高波形进行重定，认为优化的Threshold算法是几种波形重定算法中最稳健的重定算法，适合于地中海近岸海域EnviSat测高波形的重定，对其他近岸海域的应用也有一定的参考意义。

Methods Eight hundred metres fast walking on a flat ground and semisupine cycling exercise test were performed in 18 patients randomly programmed to VVIR or VVI pacing mode and compared.

18例老年患者分别在具频率应答与无频率应答状态下做800米快速行走及症状记分和半卧位踏车运动评价。

Objective:To compare the response control and attention of Schizophrenic patients with that of the healthy controls by Integrated Visual and Auditorycontinuous performance test. To quantitate the impairment of cognitive function in patients, and to explore the relationship between cognitive function and the severity of the disorder.

目的：探讨精神分裂症病人在IVA持续操作测试中的反应控制能力、注意力等，并与健康人进行比较，从而量化精神分裂症病人的认知功能损害，并进一步探讨其认知功能与疾病严重程度的关系。
