It proved that yellow-mutant belongs to the type of absence of chlorophyll; etiolation had relation to the lack of chlorophyll.The biology characteristic of the yellow-mutant cultured in vitro was investigated. The results showed that the mutant behaved etiolation character in different temperature and illumination time condition.

在离体培养条件下，探讨了桑树黄化突变体的生物学特性，发现在不同温度及光照条件下均表现黄化特征，证明该突变体叶色黄化与否与温度变化无关，不属于温敏型或光敏型叶色突变体，但突变体的黄化程度受温度影响而有一定的变化。

ELISA method was used for the serum PSA measurement among the 3o cases of PC sufferers. Results: 5 cases of NP were all ploidy (2C and 3-4C); 23 out of 30 PC cases were euploidy. As PC levels increased, the ploidy rate increased accordingly; in 25 cases of PC sufferers, the serum PSA was higher than normal; in 6 Out of 7 ploidy sufferers, the serum PSA was abnormal; 4 out of 5 normal PSA are euploidy.

结果：5例NP中均为整倍体（2C和3-4C），30例PC中有23例出现非整倍体，并且随着PC分级的增高，其倍体率也增大；25例前列腺癌患者血清PSA值高于正常值。7例整倍体患者6例血清PSA不正常，5例PSA正常者中4例为非整倍体。

However, the difference between Hongge and Xinjie is also apparent, perhaps reflecting the source difference in the mantle. Relative to the Hongge intrusion the Xinjie intrusion is more depleted in Nd isotope ratio and enriched in REE and LILE. The Xinjie intrusion plots in the first quadrant in Sr-Nd diagram, which shows the Sr isotope-enriched and Nd isotope-depleted slightly feature. This indicates that the source of the Xinjie intrusion may had the mantle wedge signature.

但红格、新街岩体的源区又有所不同，新街岩体较红格岩体Nd同位素更亏损，稀土和大离子亲石元素更富集；新街岩体在Sr-Nd相关图上，位于第一象限，显示Sr同位素富集，Nd同位素略亏损特征，指示了新街岩体的源区可能有残留地幔楔的成分。

The objective of the thesis is to present newly developed AC driver and protection circuits for light emitting diode. The LED modules for each upper and low arm are with pulse-width modulation control in every half fundamental cycle. The indication and protection circuits act whenever short circuit and open circuit of LED module occur. Moreover, the current path is switched off when there is a short circuit of LED module.

目前一般白光发光二极体的驱动器，皆是使用直流电源驱动，本文利用发光二极体本身单向导通的特性，将发光二极体串接成桥式整流器的方式，只需控制流经中间路径的电流周期，就可达到调整发光二极体亮度之目的，并且增加发光二极体故障时的保护指示电路。

According to the statistics of 2615 enclaves in 53 enclave observation spots, enclaves in Fangshan granodiorite are divided into two categories, xenolith enclave and microgranular enclave.

依据53个观察点2615个包体的统计，将房山花岗闪长岩体中的包体划分为捕虏岩包体和微粒包体两大类。

If 〓mRNA positive expression, its DNA heteroploid type display as triploid or hypodiploidy, if 〓mRNA negative expression, its DNA heteroploid type display as hyperdiploidy、tetraploid or Bistem line. These from one flank demonstrate the role of 〓 gene suppress the proliferation of malignant tumor

表达阳性者，其DNA异倍体主要表现为三倍体或低二倍体，〓表达阴性者，其DNA异倍体主要表现为高倍体、四倍体和双干系，从一个侧面显示出〓基因的抑制恶性肿瘤细胞增殖的作用。

By using molecular dynamics simulation, the deposition process of cold spraying nano-scale Au particles on Au (001) surface and the morphological changes of the surface layers of the substrate and the particle are described, in which the many-body potential was used to calculate the interatomic force between the atoms.

通过对Au纳米粒子在Au基体上沉积过程的分子动力学模拟，再现了冷喷涂中Au纳米粒子在Au基体上沉积的过程以及粒子和基体表层的形貌变化；在撞击过程中，基体的局部区域有熔化现象，通过计算粒子原子进入基体表面层的数量及粒子与基体间的最终接触面积，探讨了影响喷涂粒子沉积过程的主要因素。

Molecular dynamics simulation was carried out to study transformation pseudoelasticity in NiAl alloy with a initial B2 structure, using EAM type interatomic potential for NiAl.

利用NiAl合金的嵌入原子势，进行了B2结构NiAl单晶中相变伪弹性的分子动力学模拟模拟过程中系统的径向分布函数和键连线原子分布图的变化表明，在外加拉应力的作用下，B2结构的奥氏体向L10结构的马氏体转变，马氏体在长大过程中发生了变体间的转化与合并，不同取向的变体之间由于自协调效应形成共格的孪晶界面。

Isothermal quenching treatment is one of effective methods to improve properties of austenitic-bainitic steel.

等温淬火是提高奥氏体-贝氏体钢性能的重要手段，选择合理的奥氏体化温度对提高奥氏体-贝氏体钢性能具有重要意义。

To find these memory mapped expansion ROMs during boot, PC BIOS implementations scan real memory from 0xC0000 to 0xF0000 on 2 kilobyte boundaries looking for a 0x55 0xaa signature, which is immediately followed by a byte indicating the number of 512 byte blocks the expansion ROM occupies in real memory.

为了在开机时找到这些记忆体映射的扩充唯读记忆体，PC BIOS 会扫描实体记忆体，从 0xC0000 到 0xF0000 的 2KB 边界中寻找 0x55 0xaa 记号，接在其后的是一个位元，表示有多少个扩充唯读记忆体的 512 位元区块占据真实记忆体空间。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
