As known as traditional viewpoint, microbe could produce hydrogen continuously only when microbic cell is fixed, so present tests of this process offen adopt this process fixed-cell technology of pure microbe and were in the scale of batch fermentation test. Now the larggest ability of bio-producing hydrogen was 20mLH〓/g biomass·h produced by Rhodospirillum rubrum and 1. 6mLH〓/g biomass·h produced by Clostridium butyricum .

传统观点认为，微生物惟有进行细胞固定化才能达到持续产氢，所以现有试验常采用纯种细胞固定化技术，且尚处于分批培养试验阶段，最大产氢能力深红螺菌为20mLH〓/g菌体·h，丁酸梭状芽孢杆菌为1.6mLH〓/g菌体·h。

However, compared with their parents, these plants showed some degeneration. Aside from pure diploid plants, mixoploid plants also were obtained by inducing of DMSO. Furthermore, there was much cytology behavior variation of mitosis between pure diploid and mixoploid plants.

DMSO诱导玉米孤雌生殖除获得纯合二倍体植株外，还获得了部分的混倍体，细胞染色体有丝分裂细胞学行为也相对有较大的变异。

The structure parameters of the component are further varied, to obtain multivarious frequency components. The resonance frequency of a component is reduced by filling high permittivity medium, and this makes it possible to keep the design of a component compact at low frequency even.

进一步改变结构参数，可获取不同谐振频率的器件，且可在腔体中填充高介电常数介质来减小器件的谐振频率，克服了以往使用腔体结构在低频段时体积过大等问题。

It shows that phytolith has its own advantage in paleoevironmental reconstruction of peat bogs, and will be of great help in discriminating the palaeoclimatic change.

对泥炭沉积中的植硅体进行了分析，初步证实植硅体对重建泥炭地古环境变迁模式起着重要的作用，对提高古气候变化的分辨率有很大的帮助。

Abundant peridotitic xenoliths had been found in the Dashihe Cenozoic basalts in Jiaohe of Jilin Province, northeastern China.

吉林省蛟河市境内大石河新生代玄武岩中含有丰富的地幔橄榄岩包体，详细的岩石学与矿物学研究显示，这些包体的主要岩石类型为尖晶石二辉橄榄岩-方辉橄榄岩，未发现石榴石橄榄岩。

Early hydration characteristics and paste structure of complex binding material containing high-volume steel slag were studied by the determination of hydration heat evolution, type of hydration products as well as micromorphology of hardened paste using calorimetry, X-ray diffraction, pressure porosimeter, and envirnoment scanning electron microscope.

通过对胶凝材料早期水化放热性能和水化产物种类的测定，以及对硬化浆体显微形貌和孔结构的观察，研究了大掺量钢渣复合胶凝材料的早期水化性能和硬化浆体结构。

The tested parameters included: the effect of preculture duration for explants, the type of microcarriers, density of microcarrier particles used for DNA preparation, the effects of osmotic treatments, and plasmids with various constructions. Parameters of biolistic device including the flight distance of microcarriers (6 and 9 cm) and macrocarriers (4, 8, and 12 mm) were investigated.

评估之因子包括：培植体预培养天数、微载体种类及用量、高渗透压处理及转殖质体对转殖之影响；基因鎗测试之条件有：微载体至射击目標之飞行距离(6、9 cm)，大载片至挡片之距离（4、8及12 mm）。

The results showed that 7-day-precultured embryogenic calli had the best responses for bombardment among 2-7 day' preculture duration. Enhanced transformation efficiency was found in the explants treated with high osmotic medium 4h prior to till 24 h after bombardment. Particles of gold and tungsten were both found suitable for rice transformation and there was no adverse effect when tungsten particles were reduced to 1/3 standard amount for DNA precipitation on transient GUS gene expression. However, it was found that gold particle had higher GUS expression at 120 h post-bombardment. A preliminary microprojectile transformation system with an average of 15-20 blue spots/explant GUS expression was routinely obtained for 'Tainung 67' by using the particle gun with 1,100 psi rupture disk, 6 or 9 cm microcarrier flight distance and 4 mm of macrocarrier flight distance setting.

初步结果显示，以预培养2~7日之胚性癒合组织逐日测试转殖率，以预培养7日之培植体表现最佳；培植体於转殖前4小时至转殖后24小时以高渗透压培养基处理，有助於转殖效率之提高；比较金、钨粒子对转殖率在转殖后48h並无不同，但转殖后120 h取样，则金粒子组有较高之蓝点数；钨粒子用量可减少至1/3標准用量对转殖率並无影响；利用基因鎗在使用1， 100 psi裂碟片、大载片至挡片之距离为4 mm、微载髁至射击目標之飞行距离6或9 cm之设定，GUS基因表现之平均蓝点数均可达15~20个／培植体。
