In the second part, emphasis is put on the multiple capacity of orthogonal coded spread-spectrum multiple access system with coherent and noncoherent demodulations. The multiple access capacities of uncoded system and error -correcting coded system are compared. The capacity improvements which result from the use of diversity techniques are also studied.

第二部针对正交码扩频多址系统中多址容量的问题，分析比较了采用纠错码和不加纠错码时OC-SSMA系统的多址容量，并研究了分集技术的采用对OC-SSMA系统容量的提高，指出在信息速率及码片速率相同的条件下，正交码扩频系统的性能明显优于常规扩频系统。

Valinomycin, a photophosphorylation uncoupler, decreased significantly the fast phase (related mainly to the membrane electric potential) millisecond delayed light emission of C. reinhardtii. Nigericin, another photophosphorylation uncoupler, decreased the slow phase (related mainly to the proton gradient) and partly also the fast phase of ms-DLE. Both valinomycin and nigericin can decrease the net ATP content under light and photosynthetic rate of C. reinhardtii, but the degree of inhibition of net ATP content and photosynthesis by nigericin was higher than that by valinomycin.

光合磷酸化解联剂缬氨霉素显著降低衣藻毫秒延迟发光的快相，对慢相影响不大；另一个光合磷酸化解联剂尼日利亚菌素则显著降低衣藻毫秒延迟发光慢相（主要与跨膜质子梯度有关），同时也降低部分快相。valinomycin和nigericin均可降低光下藻细胞中的ATP净含量和光合作用速率，但是nigericin对ATP含量和光合作用速率的抑制程度比valinomycin强。

Due to the fact that water molecule acquired energy from magnetic field and the molecule rotated faster after magnetization process, the growth speed of Escherichia-coli cultivated with magnetized water is faster than that cultivated by unmagnetized tri-distilled, which proved that magnetized water possesses stronger penetrability and solvency.

蛋白质水接触的几率也随之增加，所以磁化水对于蛋白质的结构将有一定的影响。由于磁化过的水水分子活动加快，并获得了高能量，使磁化水培养的大肠肝菌生长速率比普通三蒸水培养的大肠肝菌生长速率快，这就进一步证明了磁化水具有较强的渗透性和对可溶性物质的溶解能力。

The degradation of DDTs fitted pseudo-first-order kinetics equation. The constants of degradation rate of DDTs between sterilized control and unsterilized control as well as between sterilized laccase addition and unsterilized laccase addition were close respectively, with the latter much higher than the former.

DDTs的降解过程符合拟表观一级动力学方程，非灭菌对照处理和灭菌对照处理之间，以及非灭菌加酶处理和灭菌加酶处理之间DDTs的降解速率常数分别相近，且加酶处理的降解速率常数明显高于对照处理。

Markstein length increases with the increase of dilution ratio when equivalence ratio is less than 1.4, and the flame stability tends to increase with the increase of dilution ratio. The ratio of unstretched laminar burning velocity with and without diluent is only related to the dilution ratio and is little influenced by the equivalence ratio.

丙烷－空气－稀释气混合气随稀释系数的增加，火焰传播速率和层流燃烧速率降低，在当量比小于1.4时，随稀释系数的增加，马克斯坦长度值增加，火焰前锋面的稳定性趋势增加。

The activities of C4 photosynthesis enzymes in untransformed rice were very low,while those of corresponding enzymes in different transgenic rices were all highly expressed.

在高光条件下，与原种相比较，转PPDK基因水稻的光合速率未增加；转ME基因水稻的光合速率降低了6.1%；转PEPC+PPDK双基因水稻与转PEPC基因水稻相近。

Nearly all the ppc transgenic rice lines showed higher Pn （up to 68.8 %） than untransformed plants grown in dry field and full sunlight.

以上结果表明水稻中导入ppc基因可以提高其光合速率，特别是逆境条件下的光合速率。

Firstly, MRED compares the send rate upbound of the TCP throughput modal with the tartet rate of the UDP flows, and then the relation curves can be gained about throughput and packets drop probability. Secondly, by controlling the packets drop probability on the network nodes, the throughput of the UDP flows can be adjusted and transforms the response manners to the network congestion.

MRED算法根据TCP吞吐量模型发送速率上界与UDP业务流的目标速率比较，得到吞吐量与数据包丢失率关系曲线，通过在网络节点控制数据包丢失率来调节UDP业务流的吞吐量，可以改变其对于网络拥塞的响应方式。

The results show that the alloy undergoes obvious plastic elongation, the specimen fractures into four sections and the diameter changes from 16 mm to 12 mm. The fracture surfaces distribute randomly well developed and partially developed veinal patterns. The deformation behavior of alloy is non-Newtonian flow behavior. About 3% amorphous matrix of extruded specimen transforms crystal, the crystal particles with size of 10-20 mm are precipitated in the amorphous matrix, the thermostability of the extruded specimen was lowered. The failure of the alloy is mainly attributed to non-uniform viscous flow under high strain rate resulting from the hydrostatic extrusion process.

结果表明：非晶合金在高应变速率下产生了明显的塑性变形，直径从16 mm变为12 mm，断裂为4段，且样品断口上随机分布着充分发展与未充分发展的脉纹式切变带，由此可看出非晶合金的变形为非牛顿体变形行为；挤压后的样品约有3％的非晶相发生晶化，在非晶基体上析出10～20 nm的纳米晶粒，导致挤压后非晶合金的热稳定性降低；静液挤压高应变速率变形条件使非晶合金产生非均匀流变，是造成非晶合金断裂的主要原因。
