The results of absorption spectra of chloroplasts showed that NO alleviated the effects of Cd on absorption spectra of chloroplast by raising the relative absorbance at 436 nm,480 nm and 470 nm,which caused lower contents of carotinoid and chlorophyll.
结果发现,Cd对叶绿素a、叶绿素b和类胡萝卜素含量都有不同程度的降低,NO处理缓解了Cd的影响,使叶绿体室温吸收光谱的吸收率提高;Cd导致686 nm处峰偏移4 nm,峰值降低33%,734 nm处峰值降低23%,外源NO缓解了Cd对光合系统的影响,使得叶绿体低温荧光光谱在686和734 nm的峰值分别仅下降17%和10%;以DCPIP为人工电子受体, Cd处理的叶绿体中DCPIP还原速率较慢,光合电子传递(H2O→DCPIP)速率降低1.5倍,外源NO处理显著缓解了Cd对电子传递链的抑制,使其光合电子传递速率恢复到对照的水平。

Under the condition of running on the hard soil pavement with the total train mass, the riding comfort tests of the tractor-trailer combinations with the stiff and the flexible drawgear have been performed, and the dynamics longitudinal force has been studied. When the flexible drawgear was used, the theoretical results and the experimental data showed that the peak value of the dynamics longitudinal force, the peak value of the RMS of the dynamics longitudinal force, and the PSD both of the dynamics longitudinal force and of the longitudinal acceleration decreased largely.

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P<0.01~0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P<0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.
静息状态下收缩时间间期与年龄无相关性,负荷后即刻,老年组射血前期延长(P<0.05),射血前期与射血期比值加大(P<0.05),青年组无变化,提示年龄因素亦影响STI,但由于静息状态下得到代偿,STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化,而负荷后即刻老年组PEF延长,PEP/LVET加大,提示STI是检测左室收缩功能的敏感指标。4、随年龄增长,心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r=0.958、0.956、0.986及0.966,P均<0.001),舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r=-0.958、-0.875及-0.937,P<0.01~0.001)。

The study results indicate that as emission power increases, the peak power density on the section of a certain distance will increase firstly, then it will descend and that the peak light intensity on the section will increase with the increasing of spot radius of basic mode Gaussian beam. As the propagation distance increases, the peak light intensity on the section will descend gradually, and the laser energy will spread. The light intensity distribution exhibits straw hat shape on a certain conditions, in other word to say, the central light intensity is less than acroteric light intensity.
