Potassium-magnesium fertilizer contained a large number of calcium into the soil, but also play a role in disinfection, will be reduced as a result of continuous cropping and land compaction caused by bacteria, such as increasing the hazards of cotton, also contained potassium magnesium manganese fertilizer can reduce damping-off , and Verticillium wilt incidence, Mo can enhance the ability of cotton resistance to Verticillium wilt; and management of salinity through the potassium-magnesium fertilizer to improve the ecological balance of the soil environment, absorption of nutrients and more robust plants, their resistance to strong and difficult illness.

钾镁肥中所含的大量钙元素进入土壤后，也起到消毒作用，会减少由于重茬和土地板结等造成病菌增多对棉花的危害，同样钾镁肥中所含的锰可减少立枯病、黄萎病和枯萎病的发生，钼还能增强棉株抗黄萎病能力；而且钾镁肥通过治理盐碱，改善土壤生态平衡环境，吸收的养分多，植株健壮，本身抗逆性就强，不易生病。

Magnesium alloy AZ31 has good ductibility and medium intensity, the price is lower as compared with other magnesium alloys, it is the most widely used anamorphic magnesium alloy.

AZ31镁合金具有良好的延展性和中等高强度，而且价格便宜，是目前商业化应用最普遍的变形镁合金，但镁合金的耐蚀性差使它的应用受到很大的限制。

At the same time, the K, G, Vp, and Vs of forsterite decreased too because of density decrease 3.0% caused by H atoms replacing Mg atoms in the crystal. Water also increases the total energy of the forsterite system, i. e. the crystal stability and the power of bond were reduced at high pressure and temperature.

在常温常压下，2个氢原子置换1个镁原子会使镁橄榄石的密度降低3.0%，是波速及弹性模量减小的原因，同时使镁橄榄石体系的基态总能增加，降低矿物的稳定性和键之间的强度。

In this thesis, the crystal structure and phase transition behaviors of a andβforsterite (Mg2SiO4) at high temperature and high pressure were investigated by the first principle calculations and the quasi-harmonic Debye model. Variations of elastic properties, band structure, density of state, band gap ofαandβforsterite with pressure were calculated, and the effect ofα/βphase transition on these characters was analyzed. The effects of water on elastic modulus, sound velocity and band gap of forsterite were also simulated. Finally, the effect ofα/βphase transition and water on seismic discontinuity in earth was discussed.

To obtain more information of magnesium homeostasis in mitochondria, mTn-lacZ/LEU2 transposon library was transformed into mrs2 deletion mutant to screen for suppressor genes of MRS2. YMR166C, a member of mitochondrial carrier family, was identified as a suppressor gene of MRS2. Deletion of YMR166C gene can rescue the defects of mrs2 deletion mutant such as the decrease in mitochondrial magnesium concentration, Group II RNA splicing defect and growth defect on nonfermentable carbon source. For the first time we demonstrated YMR166C is involved in mitochondrial magnesium homeostasis.

为了增进对线粒体镁离子代谢调控基因的了解，利用酿酒酵母mTn-lacZ/LEU2转座子文库筛选MRS2的抑制基因，发现线粒体载体家族成员YMR166C基因的缺失可以挽救MRS2基因缺失的突变体的生长缺陷、II型内含子剪接缺陷，并可以调节线粒体镁离子浓度，首次发现YMR166C是线粒体镁代谢相关基因。

The multivariate linear regression analysis on specific absorption coefficients for pheophytin and chlorophyll a indicates that the specific absorption coefficients for pheophytin was much larger than chlorophyll a at 412 nm; slightly larger than pheophytin at 440nm; and about 3 times larger than pheophytin at 670 nm and 675 nm.

结果表明，412nm波段脱镁叶绿素的比吸收系数远大于叶绿素a；440nm波段，叶绿素a的比吸收系数略大于脱镁叶绿素；670、675nm波段，叶绿素a的比吸收系数约为脱镁叶绿素的3倍。

Because the atomic affinity energy of Ca-O and Be-O is lower than Mg-O,The Ca and Be aggregating on the surface of liquid Mg will priorly combined with O,forming compact oxides of Ca,Be and alloys of elements,which prevent Mg alloys from burning.

由于Ca，Be与氧的原子亲和能低于镁与氧的亲和能，聚集在液体表面的Ca，Be将优先与氧结合，生成致密的镁与合金元素的混合氧化物，阻止镁合金燃烧。
